From 1752057d3a756ca6e9027ddbaedfa682037c7d3e Mon Sep 17 00:00:00 2001 From: Marc Date: Tue, 28 Jul 2026 12:37:53 +0200 Subject: [PATCH 01/53] Add experimental OPC UA data channel framing and services to the stack The OPC UA Data Channels errata defines a streaming primitive OPC UA does not have: a named, authorized, flow-controlled, bidirectional stream of opaque bytes multiplexed onto an existing SecureChannel. Nothing had ever implemented it, so nothing had pressure-tested it. This adds the framing layer and the generated Service, DataType and StatusCode surface it needs. Generated from the model compiler inputs rather than hand-written, so the new Services take exactly the path every standard Service takes: UA Core Services.xml OpenDataChannel, ModifyDataChannel, CloseDataChannel, the three enums and the four structures StandardTypes.xml HasDataChannel, IDataChannelSourceType, DataChannelSourceType, DataChannelCapabilitiesType, the three event types and the ServerCapabilities instance StandardTypes.csv NodeIds pinned in the provisional 65000+ block the errata assigns, so a future assignment by the OPC Foundation is a one-line change UA Status Codes.xml the twelve new StatusCodes KeyValuePair moves from StandardTypes.xml to UA Core Services.xml. It has to: a ServiceType parameter is resolved against the type dictionary alone, and DataChannelParametersDataType.ContentParameters is a KeyValuePair array. The generated type is unchanged, which the whole solution building against it demonstrates. The engine lives in Opc.Ua.Core/Stack/DataChannels: Framing the STR MessageChunk, the twelve-byte stream header, the optional Deadline, seven frame types, five flags, and a decoder that bounds-checks every field against the length its own FrameType and flags imply before reading it Sequencing serial arithmetic over 2^32-1 rather than 2^32, because zero is excluded from the value space and using 2^32 turns the wrap into a spurious gap; the replay window and the absolutely bounded GAP-run set FlowControl per-direction channel and connection credit, the zero-start bootstrap, and the replenishment obligation without which a receiver can legally stall a channel forever Scheduling the send queue, FrameSequenceNumber assignment at enqueue, and deadline expiry that reports one GAP run per contiguous discard DataChannel the per-direction state machine, including that Paused and Closing are both per-direction and that receiving END never starts the local drain clock Manager deficit round robin, the connection window, ChannelId allocation and the bounded buffering of frames that overtake their own OpenDataChannel response Service traffic keeps its precedence structurally rather than by a second scheduler: the transport already serializes writes in arrival order, so a MSG, OPN or CLO chunk that becomes ready while a frame is being written is admitted immediately after it. STR dispatch is wired into both channel implementations but is inert until EnableDataChannels is called, which is what the interoperability rule requires of a peer that does not implement the errata: a capable peer never speaks first. Every new public type carries [Experimental("DataChannels")] under #if NET8_0_OR_GREATER, matching the existing KeyCredentialBridge pattern. Verified against the specification's own bytes: the thirteen published hex vectors decode to the expected fields and re-encode byte for byte, and the framing and sequencing test assertions carry their DCF and DCP identifiers in the test names. Found while implementing: the errata gives OpenDataChannel a transportChannelId parameter in both the request and the response. No OPC UA service reuses a parameter name across the two, and the model compiler enforces it, so the response parameter is revisedTransportChannelId here and the specification needs the same correction.

Negotiation (Part 4 errata 5.1.1). The server revises rather than rejects wherever it can, because a client that asked for more than it can have usually wants the largest amount available. Direction and DeliveryMode are the two exceptions and are rejected outright: silently downgrading to a stronger guarantee adds unbounded latency to a media channel, and silently downgrading to a weaker one loses data. Zero means "no preference" in every numeric member -- except Priority, where zero is the lowest of the eight real priorities and 255 is the sentinel. Without that distinction IDataChannelSourceType.Priority could never take effect. InitialCredit is revised *up* to at least MaxFrameSize, because a window smaller than one frame is an immediate deadlock: the channel opens Paused and the first frame can never be sent. Service handler. Every Service in the set is scoped to both the SecureChannel and the authorizing Session, not to the SecureChannel alone. OPC 10000-4 permits several Sessions on one SecureChannel and they share one ChannelId space; since ChannelIds are allocated monotonically from one and are therefore trivially guessable, SecureChannel-only scoping would let one user enumerate and seize another's channels. A channel owned by another Session returns Bad_DataChannelIdInvalid, indistinguishable from an unassigned identifier. Authorization is re-evaluated rather than granted once, because a channel is long-lived and moves content out of the server continuously and outside the Service path -- a permission checked only at open is a permission that cannot be revoked. The SecurityMode floor is enforced by the *server*: a rule only the attacker is asked to obey is not a rule. Offers are single-use, scoped to their SecureChannel and expiring, so an unsubscribed client leaks nothing. QUIC peer binding (Part 6 errata 7.6.1). The TransportSecured profile rests on the premise that the TLS connection carrying the frames terminates at the same application the control stream authenticated. That premise is not self-evident: any party able to terminate QUIC between the two byte-forwards the end-to-end-secured control stream so that OpenSecureChannel, CreateSession and ActivateSession all succeed and every certificate check passes, while reading, modifying, dropping and injecting every frame in the clear. Both ends would report a fully authenticated SignAndEncrypt channel. So the binding is by key, not by name. Equality of an ApplicationUri subjectAltName is necessary but not sufficient -- CA and GDS implementations commonly populate that SAN from the requester's own CSR without checking it against an authoritative registry, so an attacker holding any certificate from an accepted anchor could otherwise name the victim's ApplicationUri. The test for DCQ-007 builds exactly that certificate and shows the two are separated only by the key comparison. Six more tests, 76 in total, all green. Documented in docs/DataChannels.md, including what is implemented and what is not.

A multi-chunk frame would sit in the existing chunk assembler +and block every other Message on the connection until it completed — the precise failure +a streaming layer exists to avoid. + +**Service traffic keeps precedence structurally, not by a second scheduler.** The +transport already serializes writes in arrival order, so a `MSG`, `OPN` or `CLO` chunk +that becomes ready while a frame is being written is admitted immediately after it. The +maximum delay is one frame, which is exactly what the specification requires. + +**The sequence arithmetic uses modulus 2^32−1, not 2^32.** Zero is excluded from the +`FrameSequenceNumber` value space, so with modulus 2^32 the wrap from `4294967295` to +`1` computes as a distance of two and the receiver reports a gap that did not happen. + +**Only `DATA` advances `HighestReceived`.** If a `GAP` advanced it, the `GAP` announcing +an expiry would push `HighestReceived` past a lower-numbered frame that survived and is +still to be transmitted, and the receiver would discard as a duplicate precisely the +frame the per-run rule exists to protect. + +**`Paused` and `Closing` are both per direction.** Receiving `END` marks the *peer's* +direction ended and nothing more: it never starts the local drain clock and never stops +the local application enqueueing. That is what makes `END` a half-close rather than a +close, and it is why a long upload survives the other end half-closing. + +**`IsFinal` is `F` and nothing else.** An Abort chunk's secured body is `Error` followed +by `Reason` per OPC 10000-6 §6.7.3, so accepting `A` would let that parser read a 32-bit +string length out of the attacker-controlled `FrameType`, `Flags` and `Reserved` bytes +of the stream header. + +## Deviation from the errata + +`OpenDataChannel` in the errata carries `transportChannelId` in both the request and the +response. No OPC UA service reuses a parameter name across the two, and the model +compiler enforces it, so the response parameter here is `revisedTransportChannelId`.

The SequenceNumber budget. OPC 10000-6 6.7.2.4 forbids reusing a SequenceNumber under one TokenId and discharges that by assuming the token lifetime is short relative to the chunk rate. Data channels invalidate the assumption, not the rule: STR frames consume SequenceNumbers at the data rate of the channel rather than at Service call rate. On a 10 Gbit/s link minimum-size frames exhaust the 32-bit space in about two and a half minutes, well inside a one-hour token. That is not cosmetic. Where a SecurityPolicy derives a per-chunk IV or AEAD nonce from the SequenceNumber, reuse under one key is a cryptographic failure; where it does not, replay detection silently degrades, because a stack checking only "incremented by exactly one" accepts the wrap. The budget renews early *and* stalls late, because a slow renewal can be overtaken by a fast channel: SendDataChannelFrameAsync refuses the chunk that would reuse a value rather than renumbering it. The renewal threshold is the lesser of 2^30 values and one minute of measured traffic, which is what makes it work at both ends of the rate range -- a slow channel renews on the fixed headroom and never renews needlessly, a channel fast enough to burn 2^30 inside a minute renews on its own rate. The opc.quic binding, in its own net8.0+ assembly because System.Net.Quic needs a runtime Opc.Ua.Core cannot require. It carries the UACP conversation on the first client-initiated bidirectional stream byte for byte as over opc.tcp -- so it implements IUaSCByteTransport and the UASC pipeline above it is unchanged -- and adds IMultiplexedByteTransport for the stream-per-data-channel mapping that the chunk-at-a-time interface cannot express. RESET is realized as QUIC RESET_STREAM carrying the StatusCode as its application error code. Fallback is not permitted to be a downgrade. Blocking UDP on 4840 is a single firewall rule, so an unconditional fallback would hand an off-path attacker a downgrade primitive; IsAcceptableFallback refuses any endpoint weaker than the one required of the QUIC endpoint. Unreliable datagrams are *not* implementable here and the binding says so rather than pretending. QuicConnection exposes no RFC 9221 datagram API through .NET 10, so MaxDatagramSize is zero, SupportsUnreliableDatagrams is false, and a request for Unreliable or PartiallyReliable is refused with Bad_DeliveryModeUnsupported -- which is what the errata requires, because silently carrying them on the channel's stream would deliver a reliability guarantee the application did not ask for and did not budget latency for. A loopback suite that runs two managers against each other over an in-memory transport, encoding and decoding every frame on the way so the loop exercises the real codec rather than passing objects across. It is what turns the per-clause unit tests into evidence that the parts compose: the connection-credit bootstrap actually unblocks both directions, ascending delivery holds under load, a PING is answered while credit is exhausted, receiving END really does leave the receiver's own direction open, and a RESET carrying Good reaches Closed on both peers while a Bad one reaches Faulted. Close, Reset and TryPing move from internal to public on DataChannel. An application holding a channel has to be able to close it; that they were internal was an oversight the loopback tests exposed immediately. 98 tests on net8.0 and net10.0, 93 on net472, all green. Solution builds across all six target frameworks with no new warnings.

This makes opc.quic a transport a client can actually connect over: connect, open a SecureChannel, create a Session, call Services, and carry data channels on per-channel QUIC streams. The listener is plumbing rather than a rewrite. Opc.Ua.Bindings.Https already proves an ITransportListener can live outside Core and drive a TcpServerChannel through Attach and StartReceiveLoop, so the QUIC listener accepts a connection, accepts its first bidirectional stream as the control stream, and hands that to the existing UASC server implementation. Chunking, security, token renewal and session dispatch are reused untouched. The binding targets net9.0 and net10.0. System.Net.Quic is still behind [RequiresPreviewFeatures] on net8.0, and opting in would emit an assembly attribute that every consumer would have to opt into in turn. Core itself still builds for all six target frameworks. ALPN is offered and enforced. A QUIC endpoint serving some other protocol on the same port is abandoned rather than mistaken for an OPC UA Server. Data channels over QUIC set HasTransportFlowControl, so no CREDIT frame is sent or expected and Paused follows QUIC's own blocking; duplicating the window in two layers gains nothing and deadlocks when the two disagree. RESET becomes RESET_STREAM carrying the StatusCode as its application error code. Unreliable datagrams stay refused with Bad_DeliveryModeUnsupported. QuicConnection exposes no RFC 9221 datagram API through .NET 10, so SupportsUnreliableDatagrams is False. Refusing is what the errata requires; silently carrying an unreliable channel on a reliable stream is not. Fix a scheduler bug that capped a channel at one quantum per idle tick. A round's deficit is (Priority + 1) x MaxFrameSize, one frame, and the loop then waited 20 ms for the next tick, so a saturated channel moved about fifty frames a second. A round that leaves payload queued now schedules the next one immediately. The sample measured 0.5 Mbit/s before and 1.3 Gbit/s after, and ManyFramesDrainWithoutWaitingForTheIdleTick fails if the wake is dropped again. The unit tests never caught this because none of them measured time; the bug surfaced the first time the sample was run. Also wires the DataChannelCapabilities Object, whose absence is precisely how a server declares it does not support data channels, and adds samples/ConsoleDataChannelStreaming, which drives the same application code over --transport tcp and --transport quic against the same server. 103 data channel tests pass on net9.0 and net10.0, 94 on net472 and net8.0 where the QUIC tests do not apply. Every QUIC test is guarded by QuicConnection.IsSupported so an agent without msquic skips rather than fails. Opc.Ua.Core.Tests shows no regression at 4134 passing.

All rights reserved. * From 217428d363b174f7c0803854eb2354a9796e3234 Mon Sep 17 00:00:00 2001 From: Marc Date: Wed, 29 Jul 2026 08:49:03 +0200 Subject: [PATCH 05/53] Raise data channel and QUIC test coverage to 87.6%, fixing three defects Coverage of the data channel and opc.quic code was 49.6%. The existing 103 tests concentrated on framing, sequencing and negotiation -- the parts easiest to unit test -- while roughly a quarter of the code had no test referencing it at all. This adds 123 tests across eleven files and takes line coverage to 87.6%. The gaps that mattered were not the largest ones. DataChannelServiceHandler is the whole server-side Open/Modify/CloseDataChannel surface, the most specification-visible code in the change, and none of its eleven StatusCode branches were asserted. QuicTransportListener is the accept path, and the existing QUIC harness built raw System.Net.Quic listeners itself, so the listener had never run in a test. Both are now covered end to end, which retires the standing caveat that the listener had never been exercised through a real server flow. Measuring first also found a file the reference map had missed entirely: Stack/Tcp/UaSCBinaryChannel.DataChannels.cs, the inline TCP STR dispatch, at 0% across 115 lines. It sits outside Stack/DataChannels/ and only the coverage report caught it. Writing the tests found three defects, all in code the pre-existing end-to-end tests had executed without asserting. QuicTransportListener captured the TLS certificate in the accept callback's closure, so CertificateUpdate moved the UASC layer to the rotated certificate while TLS kept presenting the retired one. That breaks the very key-equality check of Part 6 errata 7.6.1 that the errata exists to enforce, and leaves a revoked or expired certificate in use until restart. The callback now reads a field, endpoint descriptions are refreshed the way the TCP listener already did, and retired certificates are held until close so an in-flight handshake is never pulled out from under. QuicConnectionBuilder.ConnectAsync caught only QuicException. An ALPN or certificate rejection surfaces from the TLS handshake as AuthenticationException, so it escaped as a raw platform exception and callers using the stack's catch (ServiceResultException) idiom missed ALPN failures entirely. It now maps to Bad_SecurityChecksFailed. DataChannel.TryPing had no channel-state guard although Write guards Closed and Faulted. On a dead channel it took a sequence number, enqueued a PING, re-woke the scheduler and latched m_pingOutstanding, so the channel could later be declared dead by a ping that should never have been sent. TryPing is public API. It now returns false, matching the Try* contract. Also guards the discard-path receive credit Release with !HasTransportFlowControl, matching TryAccount. Over QUIC the two were asymmetric, so discarded frames accumulated credit that was never accounted. Inert in practice because the only consumer sits behind the same guard, but it published a misleading diagnostic. The tests assert behaviour rather than reachability, because this code has already shown that the difference matters: the 2600x scheduler throughput bug fixed earlier on this branch had every line of the scheduling loop executed by the suite and still shipped, since nothing measured the rate. 226 tests pass on net9.0 and net10.0 and 184 on net472 and net8.0, where QUIC does not apply. Every QUIC test is guarded by QuicConnection.IsSupported so an agent without msquic skips rather than fails, and there is deliberately no build-time coverage gate because a gate would fail exactly those agents. Opc.Ua.Core.Tests shows no regression at 4134 passing, and the streaming sample still runs over both framings.

One is a deadlock that would have stopped every long-lived stream in production. Connection credit was granted once and never replenished. Part 6 errata §5.8.2 says a CREDIT frame on a non-zero ChannelId grants ChannelCredit to that channel "and, if ConnectionCredit is non-zero, that amount to the connection as well". The sender put the connection grant on the wire and the encoder wrote it, but the receiver read only ChannelCredit and dropped the rest: the connection window was reachable solely through the one-shot EnsureConnectionCreditGranted. On inline framing that window is MaxCreditPerChannel x MaxDataChannels, 16 MiB by default, after which every channel stalls permanently with no way to recover. Nothing caught it because no test and neither sample moved more than a megabyte, and the streams this errata exists to carry run for hours. The manager now applies the connection grant when it dispatches a per-channel CREDIT, and faults every channel if that grant would overflow, since the connection window belongs to no single channel. The QUIC Message header sent a zero SecureChannelId. The reasoning was that the QUIC connection already identifies the SecureChannel, but §5.1 requires the field to carry the enclosing SecureChannel under both framings, and the specification's own quic_datagram_unreliable vector carries 41340. The vectors did not catch this because SpecVectors.QuicPrefix skips the first twelve bytes, so the codec was checked from the stream header onward and the message header was never compared against anything. A test now compares the emitted header to the vector, and asserts the vector's own SecureChannelId is non-zero so the comparison cannot quietly become vacuous. A same-key certificate re-issue tore down every connection. The listener matched on thumbprint, but a re-issue that keeps the key produces a new thumbprint and an unchanged subjectPublicKeyInfo. Since the binding of §7.6.1 is by key, such a connection remains consistent and §7.6.2 requires it be left alone; matching on the thumbprint aborted every live media stream on an ordinary scheduled renewal. The listener now compares the key. Unsupported frame types and payload on a frame that carries none both mapped to Bad_DataChannelLimitsExceeded, which describes neither. The errata now names Bad_DataChannelFrameTypeUnsupported and Bad_DataChannelFrameInvalid for these two faults, and they are added to the model compiler inputs as provisional 1111 and 1112. 230 tests pass on net9.0 and net10.0, 186 on net472 and net8.0. Opc.Ua.Core.Tests shows no regression at 4134 passing.

Several obligations were implemented correctly, covered by tests, and never invoked from any production path: QuicPeerBinding.Verify had eight test references and no callers, DataChannelServiceHandler was never constructed, DataChannelManager.Remove was never called. This connects them, and fixes what connecting them exposed. Security -------- The TLS peer binding of Part 6 errata 7.6.1 now runs. That check is the whole premise of the TransportSecured profile - it is what proves the TLS peer is the OPC UA peer - and without it a TLS terminating relay would read and inject every media frame while both ends reported an authenticated SignAndEncrypt SecureChannel. The comparison itself moved from X509Certificate2.GetPublicKey, the raw subjectPublicKey bits, to PublicKey.ExportSubjectPublicKeyInfo, which is the artifact the clause names and which additionally covers the AlgorithmIdentifier. A subjectAltName check against the EndpointUrl host was added beside it. Certificate rotation now behaves as 7.6.2 requires: a key change closes the connections bound to the superseded key with a QUIC application CONNECTION_CLOSE carrying Bad_SecurityChecksFailed rather than per-stream resets that may not survive the close, connection admission is fenced against an activation epoch so a handshake in flight cannot be admitted under a retired key, and a connection is closed when its own bound certificate becomes revoked, untrusted or expired. A same-key re-issue still disturbs nothing. TLS resumption is disabled for opc.quic because .NET exposes no way to invalidate outstanding tickets at activation; the errata now names that as the conforming fallback. Correctness ----------- Securing a STR chunk is now serialized against Service traffic under the channel's DataLock. Sharing the SequenceNumber sequence, which the errata already required, also means sharing the symmetric keys and the counter that produces it, and nothing serialized the two writers. The scheduler thread and a Service response reached the same HMAC concurrently: on Windows the CNG hash provider refuses outright and faulted the scheduler round, and where it did not throw it raced for SequenceNumbers and emitted duplicates, which a peer is obliged to treat as a replay. Found by running a Client against a Server, not by any test. The Session layer rejected the DataChannel request types as an unexpected RequestType, so a real Client could not reach the Service handler even once the dispatch was wired. Also found by running it. MaxDataChannels counted channels that had already ended, so a SecureChannel refused every new channel after sixteen open-close cycles with none open. The limit now counts only non-terminal states and ended channels are released. Their identifiers are never reissued, which is what still lets a Close on one return Bad_DataChannelClosed rather than Bad_DataChannelIdInvalid. DCF-006 and DCF-007 now emit the RESET the errata requires instead of silently dropping the frame; buffered frames are replayed with their real FrameType rather than as zero-length DATA, so a buffered RESET still resets; the unknown-ChannelId buffer is bounded by encoded frame size rather than payload, so zero-payload frames cannot be queued without limit; and MaxBitrate is revised against the source instead of always returning 0, which in the same table means unconstrained. MaxBitrate could not be revised before because DataChannelParametersDataType had no such field. QUIC transport -------------- Data channel direction now maps to QUIC stream type and initiator as 7.4 requires, keyed off the OPC UA role rather than the QUIC role, so reverse connect inverts the stream types without mis-assigning channels. A SourceToSink channel allocates a server-initiated unidirectional stream and returns its id in revisedTransportChannelId; a Client-initiated direction that omits transportChannelId is refused. opc.tcp is unaffected. Server side ----------- StandardServer now serves OpenDataChannel, ModifyDataChannel and CloseDataChannel, aborts a Session's channels when it closes, raises the audit events, and drives the authorization recheck on its interval and on role changes. The sample gained a server mode that opens a data channel through a real Session over opc.tcp and streams over it, which is what found the two bugs above; the direct-manager mode is kept, since that is what found the scheduler throughput bug earlier. Not fixed, deliberately ----------------------- The non-downgrading fallback rule of 7.9 has nothing to attach to: Opc.Ua.Client contains no reference to opc.quic and no cross-scheme fallback exists anywhere in it, so a Client that never falls back conforms vacuously. Wiring the predicate would mean first inventing the fallback, which is a feature rather than a fix. Client-side 0-RTT refusal is likewise unreachable: .NET exposes no early-data control on QuicClientConnectionOptions. 255 tests pass on net9.0 and net10.0 and 196 on net472 and net8.0. Opc.Ua.Core.Tests is unchanged at 4134. The one failure in Opc.Ua.Server.Tests, ConfigureApplicationBuildsSharedClientAndServerConfiguration, was verified to fail identically on the parent commit and is not a regression from this change.

Getting there needed two production fixes and one missing seam. StandardServer created listeners only for schemes in the hardcoded Utils.DefaultUriSchemes list, so a base address using any other scheme was silently ignored and no listener was ever created for it. Registering the QUIC binding therefore appeared to succeed and did nothing. It now derives the schemes from the base addresses actually configured, which fixes the general case rather than only opc.quic: any transport binding outside the built-in set was previously unusable with StandardServer, with no error to say so. ServerBase did not map opc.quic to a transport profile, so even a listener that had been created advertised an endpoint with no ProfileUri. Neither is reachable from a unit test that constructs a listener directly, which is why both survived a green suite and surfaced the first time a Client tried to reach a Server over QUIC. The missing seam was on the client. The Server reaches its data channel transport through UseQuicDataChannelTransport; a Client had no equivalent, so binding its DataChannelManager to the QUIC stream the Server named in revisedTransportChannelId meant unwrapping the transport by reflection. QuicClientChannelExtensions is the mirror of the server extension, and QuicPeerBindingTransport.Inner exposes the connection the 7.6.1 peer binding wraps, so the unwrapping is part of the contract rather than a trick. Both transports verified by running them: tcp : framing Inline, transport chan id 0, 300/300 frames, 0 stalls quic : framing Quic, transport chan id 3, 300/300 frames, 0 stalls The QUIC transport channel id is the server-initiated unidirectional stream 7.4 requires for a SourceToSink channel, allocated by the Server and returned to the Client; the zero on inline framing is correct, since there is no per-channel stream there. Zero credit stalls on QUIC is also the expected reading rather than an absence of evidence: QUIC owns the flow control on that path and no CREDIT frame is exchanged. 255 tests pass on net9.0 and net10.0, 196 on net472 and net8.0. Opc.Ua.Core.Tests unchanged at 4134.

Adds the four defects that running it found and that the suite could not reach, with why each was invisible to a test - concurrent securing of a STR chunk against Service traffic, Session refusing the request types, and StandardServer and ServerBase both ignoring any transport scheme outside the built-in list. Coverage is restated at 80.1 percent, down from 87.6 while the test count rose from 226 to 255. Wiring the uncalled obligations added production code faster than tests were added for it.

The shipped default authorizer granted everything. StandardServer fell back to a permissive IDataChannelAuthorizer that returned true unconditionally, and no other implementation existed anywhere in the tree. Part 4 §7.2 is explicit that a Server shall not grant a data channel where it would refuse a Read of the same content, so any Session - Anonymous included - could open a channel on a source whose RolePermissions deny it, and because the same object backs the periodic recheck, revocation never took effect either. The default now resolves the Session, builds the OperationContext a Service call would, and asks the owning NodeManager to validate PermissionType.Read against the source Node, so RolePermissions, UserRolePermissions and AccessRestrictions all apply without reimplementing any of them. It fails closed: an unresolvable Session or an error during validation denies. A source that is not a Node in the AddressSpace has no permissions to evaluate and remains governed by its registration, matching what ValidateRolePermissionsAsync already does for unknown Nodes. Reverse connect performed neither half of the §7.6.1 peer binding. The forward client path gets it because the transport is wrapped in QuicPeerBindingTransport; RunReverseConnectAsync built a bare transport, so QuicPeerBinding.Verify was never reached, and with ServerCertificateValidation left unset the TLS check degraded to the machine root store rather than the OPC UA trust list. An on-path attacker holding any certificate chaining to any CA in the host's store, with a SAN for the configured name, could therefore terminate TLS and byte-forward the control stream: OpenSecureChannel, CreateSession and ActivateSession all succeed with genuine certificates, both ends report an authenticated SignAndEncrypt channel, and every data channel frame - carrying no UA-SC security under TransportSecured - is readable and injectable. Reverse connect now uses the application's certificate validator and runs the two-artifact binding §7.6.2 defines for the inverted TLS roles. Per-SecureChannel data channel state was never released. The dictionary is keyed by SecureChannelId and only cleared at shutdown, and each entry holds a DataChannelManager with a running scheduler, so a peer that repeatedly opened and closed a SecureChannel accumulated them without bound. State is now reaped once no Session remains on that SecureChannel, which is also the point past which no data channel could be authorized on it anyway. The negotiated MaxFrameSize was unenforced on receive until a conforming frame happened to arrive, because the tracking field started at uint.MaxValue and was only ever lowered by a frame that already fit. A sender that never set MessageStart kept it unbounded. It now starts at the negotiated value, and the §5.2 grace window applies only from an actual ModifyDataChannel reduction. The delivery queue that compounded this over QUIC - where transport flow control means no credit accounting - is now bounded with blocking backpressure rather than a reset, so reliable delivery is preserved and QUIC's own flow control does the throttling. Pre-authentication QUIC admission state accumulated. The activation-epoch snapshot is inserted from the TLS handshake callback, before any authentication, and was only removed for connections that completed the handshake, so an unauthenticated peer that offered the right ALPN and then abandoned the handshake left an entry permanently. Entries now expire at the handshake timeout and hold a certificate reference rather than a copy. A test that asserted the old reverse-connect behaviour was rewritten rather than deleted: it configured an accept-all validator and expected rejection, which only held while the code ignored the configured validator and fell through to OS trust. It now configures a validator that genuinely refuses, which is what "fails closed when the peer is untrusted" has to mean. 258 tests pass on net9.0 and net10.0, 197 on net472 and net8.0. The sample still moves 300/300 frames over both opc.tcp and opc.quic. Opc.Ua.Core.Tests unchanged at 4134.

Four findings in the reference implementation, plus two bugs found while fixing them. Authorization no longer fails open. The default authorizer treated a source with no owning NodeManager as authorized, on the reasoning that registration is a deliberate server-side act. That was wrong: registration says the source exists, not that this user may read it. It now denies, and evaluates AccessRestrictions alongside RolePermissions as MasterNodeManager does for a real Read. Registry-only sources need an explicit authorizer, which the sample now demonstrates. The QUIC listener now performs the mutual TLS binding that Part 6 errata 7.6.1 requires, on the normal accept path and not only under reverse connect. The rule is two obligations, not one: request a client certificate on every connection, and refuse OpenDataChannel where the connection completed without one. Collapsing them into a handshake failure would make the Discovery Services unreachable, since GetEndpoints runs on a SecurityPolicy None channel that has no certificate to present. The refusal therefore lands at OpenDataChannel, with Bad_SecurityChecksFailed, rather than silently degrading to a Service-only transport. The SequenceNumber budget now observes every symmetric chunk. MSG, OPN, CLO and STR all draw from one space, and reuse under one TokenId reuses the AEAD nonce derived from it. GetNewSequenceNumber is the single chokepoint, so the hook lives there, and the client brings token renewal forward when the space runs low instead of waiting on the lifetime timer. A stream already bound to a data channel can no longer be rebound to another; it previously returned success. Two bugs found while fixing the above: The budget never actually reset. OnTokenActivated zeroed the counter, but the next synchronization re-observed the channel-lifetime m_sequenceNumber and restored it, so a per-token budget behaved as a channel-lifetime one: renewal would latch on permanently and data channels would eventually stall for good on a long-lived channel. The budget is now rebased on the counter value at activation. Wrapping the accept path in QuicPeerBindingTransport silently broke data channels over QUIC. The wrapper is what the channel holds, and it did not forward IUaSCSecureChannelBoundTransport, so the QUIC transport never registered against its SecureChannel and OpenDataChannel fell back to a Service-only transport. Caught by the sample, not by the unit suite. Validated: data channel tests 273/273 on net9.0 and net10.0, 203/203 on net472, net48 and net8.0; Opc.Ua.Core.Tests 4134; Opc.Ua.Server.Tests 3575; Opc.Ua.Client.Tests 2104; and the sample end to end over both --transport tcp and --transport quic.

The sending side did not guarantee it. A chunk's SequenceNumber was drawn inside WriteSymmetricMessage under the securing lock, but the send was deliberately awaited outside that lock so a slow peer could not block Service traffic, and TcpByteTransport.SendChunkAsync then serialized the socket write on a SemaphoreSlim that is not FIFO-fair. Assignment order and transmission order were therefore decoupled, and chunk N+1 could win the semaphore ahead of chunk N. This needs two concurrent writers on one channel to show, which is why it survived: the data channel scheduler alone stays ordered by luck. Add a Subscription and the Publish responses supply the second writer, and the channel dies with ProcessStreamMessage - Duplicate sequence number: 13907 <= 13908 ForceChannelFault ... 'a data channel frame violated the framing rules: MalformedHeader' A per-channel FIFO send gate now spans every path that hands secured chunks to the transport. A ticket is taken at the instant the SequenceNumber is drawn and under the same mutual exclusion, and a writer waits for its turn before writing and releases it afterwards, including on the failure paths - a stranded ticket would deadlock the channel. The "secure under the lock, send outside it" property is preserved. The benchmark that found it is added as --mode benchmark in the streaming sample. It measures data channel throughput against a competing Publish load at 10 ms, 100 ms and 1000 ms. Most of the work in it is refusing to report numbers that look fine and mean nothing, because this measurement fails quietly in several ways: - An early version reported that Publish load made the channel twice as fast. Every loaded case had received zero notifications: a ManagedSession defaults to the newer subscription engine, where a classic Subscription is accepted, reports itself Created, reports no item errors, and never causes a single Publish request to be sent. The benchmark now counts the notifications it actually received and says so when there are none. - The Server revises a publishing interval below its minimum and rounds it to the publishing resolution, both 100 ms by default, so a 10 ms case silently becomes a second 100 ms case that agrees with the first for entirely the wrong reason. The revised value is reported next to the requested one. - Cases run sequentially on a warming process produce a clean monotonic curve that is an artefact of the order. Cases are round-robined inside each pass. - Four medians in a column invite ranking. Where a loaded case overlaps the baseline's own run-to-run spread the benchmark states that the ranking is not supported by the data. - The Publish rate under load means nothing without the rate the same subscription reaches while the channel is idle, so that control is measured and both are reported. Measured on this machine over loopback: about 768 Mbit/s over opc.quic against 390 Mbit/s inline over opc.tcp, and no resolvable effect of the Publish load on either transport in either direction. One defect is recorded rather than fixed: the credit-stall counter is incremented over opc.quic, where credit is not in force and CREDIT frames are neither sent nor expected, so it reports hundreds of thousands of stalls on the runs with the highest throughput measured. The counter is wrong, not the transport. Validation: Opc.Ua.Core.Tests 4134, Opc.Ua.Core.DataChannels.Tests 274, Opc.Ua.Server.Tests 3575, and the sample end to end over both --transport tcp and --transport quic with no ordering faults.

Nothing had stalled. DataChannelCredit.TryConsume counts a stall whenever the send window is smaller than the payload, and the window was still consulted over QUIC, where the transport provides its own per-stream and per-connection flow control and CREDIT frames are neither sent nor expected. Both the Part 6 errata and this repository's own documentation state the counter should stay at zero there. The window is now simply not consulted where HasTransportFlowControl is true, rather than being consulted and its answer discarded - the latter is how the defect arose, and it had already been half-applied by seeding the window with uint.MaxValue, which hid the intent without removing the counting. The inline path is untouched: over opc.tcp and opc.wss the credit window is the flow control and its stall counter is a real signal. The defect was diagnostic only. The QUIC send path already bypassed credit blocking, so the ignored result never gated a send and no throughput figure was affected. Validated: the new regression test fails against the previous code and passes now; data channel tests 206 on net472, net48 and net8.0 and 276 on net9.0 and net10.0; Opc.Ua.Core.Tests 4134; and the QUIC benchmark now reports zero stalls in every case.

Four are implementation faults; two of them also exposed gaps in the draft, which are proposed separately in the drafts repository. Validate transportChannelId where the result is visible (Part 6 7.4) QuicServerDataChannelTransport.BindClientStreamAsync discarded the task carrying every 7.4 check, so a Client could name the control stream, a stream it did not initiate, or one already bound, and the Server answered Good and echoed the value. The checks were right; nothing consumed them. Validation and stream reservation now run inline where a refusal becomes the Service result. Only the wait for the stream to materialize stays deferred, because a peer-initiated QUIC stream is observable only once the peer writes to it and a Client writes only after it has the response - awaiting it would deadlock the exchange rather than order it. Stop one unread channel stalling the SecureChannel (Part 6 5.8) The delivery queue was bounded in frames but sized from a byte credit, and it blocked when full. Small frames therefore filled it long before credit ran out, and the block landed on the reader that also carries MSG, OPN and CLO, so a slow consumer on one channel stalled every Session, Subscription and Publish on the connection - the opposite of "stalls that stream and nothing else". The queue is now bounded by encoded frame bytes, as 7.4 bounds the unknown-ChannelId buffer and for the same reason, and a peer that exceeds the bound is reset rather than waited on. This also removes a sync-over-async violation. Open the channel when the response is dispatched, not before (Part 4 5.1) OnResponseSent ran before the response object was encoded, so MarkOpen could wake the scheduler and put a frame for a ChannelId on the wire ahead of the response naming it. SecureChannelContext gains an optional ResponseDispatched callback that both listeners invoke after handing the response to the transport; it is inert when unset. The scheduler additionally refuses to serve a channel still Opening, which is what the 5.13 state table already said. Carry inline data channels instead of discarding them (Part 6 5.16) A Server advertised opc.tcp, accepted OpenDataChannel, and then dropped every frame through a transport whose send path did nothing - the silent drop 5.16 forbids. InlineServerDataChannelTransport resolves the UASC channel behind the request and enables the engine on it, so channels ride the connection the Client already holds. A SecureChannel that can carry no frames is now refused with Bad_DataChannelTransportUnsupported. Give Uncertain_DataDiscarded its own identifier It shared identifier 1111 with Bad_DataChannelFrameTypeUnsupported. The two differ only in severity bits, so the collision produced valid but wrong constants instead of a build error; it is now 1113. The generator fails on a duplicate identifier and a test asserts the emitted constants are unique. Every regression test added here goes through the production entry point rather than the component, because that is precisely what the existing component-level tests missed in all four wiring defects. Opc.Ua.Core.DataChannels.Tests 284 pass on net10.0 and 212 on net48; Opc.Ua.Server.Tests 4072 pass; Opc.Ua.Sessions.Tests 776 pass with test discovery unchanged.

None of that is reachable from another assembly, so the code could not be lifted out. This adds the extension point and reroutes the existing code through it, without moving a single file. A green suite here is what proves the seam is faithful; the move that follows is then mechanical. The seam names no data channel concept. ISecureChannelMessageExtension owns a MessageType that is neither a Service call nor part of establishing the SecureChannel; ISecureChannelMessageHost is what the channel offers it. A chunk is decrypted, verified and sequence-checked before the extension sees it, so an extension never handles content the channel has not authenticated, and a MessageType with no registered owner stays a protocol error - which is what OPC 10000-6 6.7.2.2 requires of a receiver that does not implement it. The send is the delicate part. Assigning the SequenceNumber and applying message security stay serialized against Service traffic, because both draw on the same keys and the same counter, and the callback the extension passes runs inside that serialization so it can refuse the send atomically. That is what the data channel SequenceNumber budget of Part 6 5.1.1 needs, and it is why the callback exists rather than a plain "encode then send". The write itself is still awaited outside the serialization, so a slow peer on an extension cannot stall Service traffic. The callback is cached, so a frame allocates no closure on the send path. The budget splits along the same line: the mechanism, how many SequenceNumbers this channel has issued under the token in force, belongs to the channel; the policy of when to stall belongs to the extension. DataChannelExtension is now the only thing that knows the frame format, and the protected virtual OnDataChannelProtocolFault it replaces becomes an event, so which framing rule was broken is still observable - a transport error alone does not carry it. Opc.Ua.Core.Channels is scaffolded here but still empty; the engine moves into it next. Opc.Ua.Core.DataChannels.Tests 284 pass on net10.0 and 212 on net48; Opc.Ua.Sessions.Tests 777 pass, which is the suite that would notice a change to the shared receive and send path.

Opc.Ua.Core.Channels references Opc.Ua.Core and nothing else, ships as OPCFoundation.NetStandard.Opc.Ua.Core.Channels, and targets the same six frameworks as Core so the net48 coverage survives. What moved: the twenty-one engine files, the data channel half of the UASC partial - now extension methods, because a partial class cannot span assemblies - and IServerDataChannelTransport with InlineServerDataChannelTransport, which turned out to touch only SecureChannelContext, Profiles and the engine. What deliberately did not. StandardServer.DataChannels.cs is a partial of StandardServer, so it cannot move at all; its Service overrides and the authorizer and auditor that read ServerInternal, MasterNodeManager and node states are server concerns and stay. Opc.Ua.Bindings.Quic stays its own net9.0+ package: System.Net.Quic is behind RequiresPreviewFeatures on net8.0, and it references Opc.Ua.Server, so folding it into a Core.* package would put that package above the Server layer. Two things moved the other way, because they are the SecureChannel's own concerns rather than the feature's. DataChannelSequenceBudget becomes SequenceNumberBudget in Core: the space is shared by MSG, OPN, CLO and every extension alike, and the client channel already used it to decide when to renew a token. Keeping one instance on the channel also removes the second, redundant budget the seam had briefly introduced. The SecureChannel registry becomes UaSCSecureChannelRegistry, since mapping an identifier to the channel that owns it says nothing about data channels. Core loses EnableDataChannels and DataChannels on both channel types, MaxDataChannelBodySize, SequenceBudget's data channel name, and the CoreEventIds.DataChannel blocks; TransportChannelFeatures.DataChannels becomes MessageExtensions. The feature is [Experimental], so removing rather than forwarding is allowed. Log EventIds keep their existing numbers in ChannelsEventIds so an operator's filters keep working across the move. DataChannelFeature carries the experimental marker in Core, because it marks the generated Service Set that Clients call, not the engine. expected-packages.txt gains Core.Channels and Bindings.Quic - the latter was packable but missing, which the file itself says should be a conscious act.

The security fix is the one that matters most. Security * Authorization was direction-blind. IDataChannelAuthorizer.IsAuthorizedAsync took no direction and the default authorizer always evaluated PermissionType.Read, so a user permitted to read a source could open a SinkToSource or Bidirectional channel and write into the Server. Part 4 errata section 7.2 names this exact failure. The interface now carries the direction, the call moved to after TryRevise so the negotiated direction is known while still preceding any ChannelId or stream allocation, and each required permission is validated on its own - ValidateRolePermissions treats a combined mask as "any of these", so asking for Read|Write in one call would have passed for a Read-only user. Wiring * AddQuicTransport() now registers the server-side data channel transport, and DependencyInjectionStandardServer resolves the transport, authorizer, auditor and sources from DI. UseQuicDataChannelTransport() stays as the direct-construction fallback. * A closed SecureChannel or lost transport now faults every data channel riding on it, on both the inline and opc.quic paths (section 5.13). This was unimplemented; only the Session-close and identity-change rows of that table were covered. * IServerDataChannelTransport.AbortSecureChannel had no caller and the QUIC implementation closed the whole connection, contradicting its own contract and section 5.11 ("a failed stream is not a failed connection"). It is now invoked when the Server tears down a SecureChannel's state, and tears down the data channels rather than the connection. Tests * DataChannelIntegrationTests: the end-to-end leg the repo requires and this feature lacked. A real Client Session drives Open, Modify and Close against a live StandardServer over opc.tcp, and payload crosses the same SecureChannel inline. It is the only coverage of the Service dispatch, per-SecureChannel state and authorization chain by a request that arrived off a socket. * DataChannelGapTests and DataChannelRefusalTests cover the GAP lifecycle and the receive-side refusals, both of which were entirely at zero: the section 5.10 protocol error, the section 5.2.1 unbounded-state guard, DATA after END, wrong-direction DATA, receive credit exhaustion and credit release on discard. * QuicListenerTests gains the public client seam (QuicClientChannelExtensions was 0/21 despite being the API a consumer uses) and the transfer handoff. * CloseChannelsForCertificateReturnsAffectedChannelIdsOnAKeyChangeAsync never called the method it was named after; renamed to what it verifies, and a real test of CloseChannelsForCertificateAsync added. * Two fixed-sleep assertions replaced with waits on an observable scheduler round counter, so the negatives are evidence rather than timing. Coverage: Opc.Ua.Core.Channels 89.8% -> 92.9% line, Opc.Ua.Bindings.Quic 79.5% -> 80.7% line, which clears the repo's 80% bar it previously missed. 311 tests on net10.0 and 237 on net48, up from 284 and 216.

Reading the errata back shows it is not merely hardening: section 5.11 states the obligation and names the attack. "PING is exempt from flow control and compels a PONG ahead of queued payload, which without a bound is an amplification surface: a peer could emit PING at line rate on every open ChannelId and compel the other end to answer at line rate ahead of its own traffic, with no window to close against it. A peer shall not have more than one unanswered PING outstanding per ChannelId, and shall not emit PING on a given ChannelId more than once per second. A receiver may discard a PING that violates either bound, and may RESET the channel with Bad_DataChannelLimitsExceeded if the violation persists." Only the sending half was implemented (TryPing, TryPingConnection). The receiving half answered every PING unconditionally, which bounds a well-behaved peer and leaves a hostile one unbounded - the responder does the work, so a rule the sender enforces on itself protects nobody. Both halves are now enforced, on the per-channel path and on ChannelId 0, which is a ChannelId and was otherwise left as a connection-level amplification surface once the data channels bounded themselves. * A PING inside the interval is discarded rather than answered. The prober keeps no state on the responder, so a dropped PONG costs it one measurement it was not entitled to take. * A peer that keeps flooding after being ignored MaxPingRateViolations times is reset with Bad_DataChannelLimitsExceeded - the errata's "if the violation persists". A single burst is absorbed silently. * The response interval carries a tolerance below the nominal one second. The sender measures the bound on its clock and the receiver on its own, so a conformant peer still delivers the occasional PING a few milliseconds early; without the tolerance ordinary jitter would be punished as a violation. * "Never answered" is tracked with an explicit flag rather than a zero timestamp sentinel, because a TimeProvider is not required to start above zero and the bound would silently never engage if it did. Tests Five tests in DataChannelRefusalTests: the verbatim Timestamp echo, the discard, recovery once the interval elapses, the escalation to RESET, and the control channel. Verified as guards by reverting the production change and confirming three of them fail. UnknownChannelBufferIsBoundedByEncodedFrameBytes counted the PONGs that a replayed PING burst produced as a proxy for how many frames had survived the unknown-channel buffer. The rate limit correctly invalidates that proxy, so it now sends DATA frames - which encode to exactly the same size, leaving the bound arithmetic untouched - and asserts FramesReceived. It measures the buffer bound it is named for rather than the ping rate limit. 316 tests pass on net10.0 and 242 on net48; Opc.Ua.Server.Tests is unchanged at 4072 passed, because this sits on the shared receive path.

A UA.slnx build pinned with CustomTestTarget builds the rest of the stack for that one TFM, which broke this project three different ways: * pinned net10.0 - the project's net9.0 leg referenced a stack built only for net10.0, so restore failed with NU1201. This is what failed the ubuntu Core.DataChannels job in 32 seconds. * pinned net472/net48 - the net9.0 leg resolved the net472 assets of Opc.Ua.Core and failed with CS0012 on IAsyncDisposable. * pinned net8.0 - System.Net.Quic is behind RequiresPreviewFeatures there, so the project cannot take part at all. The project now follows the pin when the pin can host it, and otherwise opts into the existing RestrictForLegacyTfm no-op shape that samples/ConsoleDataChannelStreaming already uses. That mechanism only knew about the .NET Framework and netstandard pins - the right floor for a .NET 8+ project - so it gains RestrictForLegacyTfmAdditionalTargets for a project whose floor is higher. The shipped package shape is unchanged: an unpinned build still produces net9.0;net10.0. Verified by running the same matrix the CI legs run. All seven pinned UA.slnx builds succeed: net10.0, net9.0, net8.0, net48, net472, netstandard2.0, netstandard2.1. That matrix also caught a break the earlier per-project validation missed: SampleDataChannelAuthorizer was never updated for the direction-aware IDataChannelAuthorizer signature, so the sample did not compile. It now grants only the SourceToSink direction it actually publishes, which is the point of the Part 4 errata 7.2 rule it demonstrates. Seam simplification The Stack/Tcp change was carrying weight it did not need. Three removals, no behaviour change: * SecureChannelMessage is gone. It crossed the boundary with exactly one producer and one consumer, was never stored or compared, and carried IEquatable, ==, != and GetHashCode purely to satisfy CA1815 - about sixty lines of ceremony. OnMessageReceived now takes the three values directly. * The onSecuring callback is gone, and with it the SequenceBudget member of the host interface. It was the subtlest part of the contract - a callback that runs inside the send serialization and may veto atomically - and its only implementation consumed the budget. Core already owns SequenceNumberBudget and is the code doing the securing, so it now claims the number itself under the same lock. The guarantee is identical and the extension no longer has to reason about the serialization at all. * GlobalChannelId is gone. It had no reader. The host interface drops from nine members to six, and Stack/Tcp from 1358 added lines to 1270. Moving the engine back into Opc.Ua.Core was considered and rejected: it would remove about 330 of those lines, none of them the hard parts - the FIFO send gate exists because there is a second writer on one sequence counter, not because of an assembly boundary - while moving 7241 lines of engine into Core on every TFM for an experimental feature. 316 tests pass on net10.0 and 242 on net48. Opc.Ua.Server.Tests (4072) and Opc.Ua.Sessions.Tests (777) are unchanged, which is the check that matters because the seam sits on the send and receive path of all Service traffic.

Both are this PR: OpenDataChannel, ModifyDataChannel and CloseDataChannel are three new Session-category Services, so the counts moving by exactly three is the intended behaviour rather than a regression. The category test now also names the three Services it expects to find, so a future change to the figure has to say which Service moved in or out of the category instead of silently renumbering.

Most of the shortfall is structural rather than untested code: Opc.Ua.Bindings.Quic is 29.8% of the changed source lines and 60 of the 316 data channel tests skip on the CI runner because msquic is not installed there, so that assembly reads close to zero in the merged report while measuring 80.65% locally, where QUIC runs. Two genuine gaps were in that list and are closed here. ManagedSession and RedundantClientSession each forward the three data channel Services to the session they wrap, and neither forwarder was exercised: the existing integration test drives ISession directly, so it never passes through either facade. A dropped forwarder would be invisible until a caller found the Service silently doing nothing, and on the redundant facade it would leave a channel opened against a session the caller can no longer reach after failover. Both fixtures already assert this obligation for every other Service, so the new cases join the table-driven passthrough suite rather than standing alone. The [Experimental("DataChannels")] opt-in is scoped to the new cases with a pragma rather than switched on for the whole test project, so the attribute keeps its meaning everywhere else. Opc.Ua.Client.Tests 2126 pass, Opc.Ua.Redundancy.Client.Tests 123 pass.

Checking every one of its symbols against Opc.Ua.Bindings.Quic gives zero references to ISecureChannelMessageHost, ISecureChannelMessageExtension, SequenceNumberBudget, the send gate and UaSCSecureChannelRegistry alike - a QUIC data channel rides its own stream and never becomes a UASC chunk, so none of it applies. The seam therefore exists to keep the engine out of Core, not to invite other implementers: there is exactly one, and no prospect of a second. Publishing it would commit Core to an abstraction with a single implementer for ever. Core already grants InternalsVisibleTo to its sibling first-party assemblies - Opc.Ua.Client, Opc.Ua.Bindings.Quic, Opc.Ua.Bindings.Https, Opc.Ua.Core.Diagnostics - and Opc.Ua.Core.Channels had simply never been added to that list, which is the only reason the seam had to be public. Adding it lets the following become internal with no code moving at all: * ISecureChannelMessageHost and ISecureChannelMessageExtension * SequenceNumberBudget, and UaSCUaBinaryChannel.SequenceBudget * RegisterMessageExtension and TryGetMessageExtension * DataChannelExtension and TryGetDataChannelExtension, which are the inline adapter rather than API - a consumer reaches the channels through EnableDataChannels and GetDataChannels, which return the engine UaSCSecureChannelRegistry stays public deliberately. An application writing its own IServerDataChannelTransport for inline framing needs it to resolve the channel behind a request, which samples/ConsoleDataChannelStreaming demonstrates; making it internal would break a real extension point to tidy an API surface. The public surface this PR adds to Opc.Ua.Core is now UaSCSecureChannelRegistry and IUaSCSecureChannelBoundTransport, the latter being a transport extension point alongside the existing public IUaSCByteTransport. This captures the main benefit of folding the engine back into Core - not owing compatibility on a single-implementer abstraction - without moving 4866 lines of experimental engine into Core on every TFM from net472 upward, and without touching the send gate or the sequence budget, both of which are inherent to inline framing wherever its code lives. UA.slnx builds pinned to net10.0, 316 data channel tests pass, and Opc.Ua.Server.Tests is unchanged at 4072.

That is correct, and checking it against the only other transport settles it: Opc.Ua.Bindings.Quic references none of ISecureChannelMessageHost, ISecureChannelMessageExtension, SequenceNumberBudget or the send gate, because a QUIC data channel rides its own stream and never becomes a UASC chunk. The seam had exactly one implementer and no prospect of a second; it existed only because the engine sat in another assembly. So the engine comes home rather than the seam being dressed up as general. The destinations are the ones commit cfaa34fa8 recorded as renames: * Opc.Ua.Core.Channels/DataChannels/** (engine, framing, flow control, sequencing, scheduling, model and Services/) to Opc.Ua.Core/Stack/DataChannels * IServerDataChannelTransport and InlineServerDataChannelTransport back to Opc.Ua.Server/Server, where the latter came from * ChannelsEventIds folded into CoreEventIds, keeping 600/620 so existing log filters are unaffected Deleted outright: * ISecureChannelMessageExtension.cs, both interfaces. This also answers the request to rename that file after its interface: it no longer exists. * UaSCBinaryChannel.MessageExtensions.cs, replaced by UaSCBinaryChannel.DataChannels.cs, which owns the DataChannelManager directly and dispatches STR after the existing decrypt, signature and sequence checks. * DataChannelExtension, the adapter that existed only to bridge assemblies. Its IDataChannelTransport half is now a small private InlineDataChannelTransport that hands the channel to the engine. * The Opc.Ua.Core.Channels project, its UA.slnx entry, its expected-packages line and its reference from the reference server Dockerfile. The package is new in this branch and never shipped, so nothing is owed compatibility. EnableDataChannels and the channel accessors become ordinary members instead of extension methods over a published seam, and the framing fault surfaces as UaSCUaBinaryChannel.DataChannelProtocolFault, so a test no longer has to reach through a registry to observe which rule was broken. This supersedes the InternalsVisibleTo narrowing in 18a30770d: the types it made internal are deleted here, and the entry it added to Opc.Ua.Core is removed. SequenceNumberBudget stays internal, which the move now justifies on its own. UaSCSecureChannelRegistry stays public because a server writing its own IServerDataChannelTransport needs it, as the sample does. Separately, per the review of the QUIC csproj, opc.quic now targets net8.0 as well and opts into preview features there, so a net8.0 consumer can do the same rather than being excluded. The three file wide NET9_0_OR_GREATER guards are gone; only QuicServerConnectionOptions.HandshakeTimeout, which is genuinely .NET 9+, stays guarded, and the listener's own admission expiry still bounds a stalled handshake on net8.0. UA.slnx builds pinned to net10.0 and 316 data channel tests pass.

The rest: Sample layout and a second sample The data channel samples now live under samples/Core, and a new ConsoleDataChannelAudio joins the throughput benchmark. It stands up a Server and a Client in one process, synthesises a short melody as 16-bit PCM once at startup and streams it on repeat over a data channel while the Client plays it back. Nothing binary enters the repository. The source writes in real time rather than as fast as the channel will take it, because a media source is paced by its own clock and writing faster only adds latency; the progress line reports frames, bytes and credit stalls so a consumer that cannot keep up is visible rather than silently buffered. Measured over 31 seconds: 1582 frames, 2725 KiB, zero credit stalls, which is exactly real time for 20 ms frames. Playback uses NAudio 2.3.0 (MIT), referenced only by that sample - nothing under src/ gains a dependency. NAudio's output devices are Windows interfaces and 2.x has no ALSA or CoreAudio backend, so on Linux and macOS the sample writes the received stream to a WAV instead and says which it is doing on startup. The Windows-only paths sit behind OperatingSystem.IsWindows() rather than a CA1416 suppression. Documentation "Where the code lives" describes where the code is rather than where it moved from, and the same edit removes "rather than in ...", "remains" and the rest of the change narration. Two sections that were a development diary - the tables of defects found while writing tests and while running the sample - are gone entirely: they recorded history rather than the state of the implementation. Logging The response-dispatched callback logged through a message that reads "Failed to send fault response to client", which is not what happened, and on the HTTPS listener it invented a requestId of 0 to fit that signature. All three listeners now have a named message that says what actually failed. net8.0 for the QUIC binding Rather than excluding net8.0, the binding targets it and enables preview features, so a net8.0 consumer opts in the same way for System.Net.Quic. The three file-wide NET9_0_OR_GREATER guards are gone; only QuicServerConnectionOptions.HandshakeTimeout stays guarded because it is genuinely .NET 9+, and the listener's own admission expiry still bounds a stalled handshake there. Removing the #if around [Experimental] ExperimentalAttribute is a .NET 8 type, and the repo's rule is to polyfill rather than fork with #if, so it joins the existing polyfills in Opc.Ua.Types. Verified that this is a real opt-in and not just something that compiles: with the suppression removed, a net48 caller of a data channel Service fails the build with "error DataChannels", which is the same behaviour as net10.0. Validated with the matrix CI runs: all seven pinned UA.slnx builds (net10.0, net9.0, net8.0, net48, net472, netstandard2.0, netstandard2.1), 316 data channel tests on net10.0 and 242 on net48, Opc.Ua.Server.Tests 4072, Opc.Ua.Client.Tests 2126, Opc.Ua.Redundancy.Client.Tests 123, and the reference server Docker image end to end.

Now mapped to `Bad_SecurityChecksFailed`. | -| `QuicTransportListener` captured the TLS certificate in the accept callback's closure | `CertificateUpdate` moved the UASC layer to the rotated certificate while TLS kept presenting the retired one — breaking the very key-equality check of §7.6.1 that the errata exists to enforce. The callback now reads a field, endpoint descriptions are refreshed, and retired certificates are held until close so an in-flight handshake is never pulled out from under. | - -The one lesson worth carrying forward: none of these were caught by coverage of the -*happy path*.

The ticket then became the tail every later send chains behind, so MSG, OPN and CLO for every Session on that SecureChannel stalled for good. Nothing recovered from it: the scheduler logs a send fault rather than faulting the channel, so the stall was silent. The ticket is now released on every path out. Releasing twice is safe because the ticket completes under Interlocked. MaxDataChannelBodySize approximated the chunk budget instead of computing it, and missed the cipher block rounding WriteSymmetricMessage applies: a 65535 byte send buffer under a 16 byte block loses its last 15 bytes. A body at the advertised size therefore spilled into a second chunk, which carries the Intermediate chunk type that the frame codec rejects, after the SequenceNumber had already been spent. It now mirrors that arithmetic. The audio sample wrote to a fixed name under the shared temp directory and truncated whatever was already there, so a local user could pre-create the path as a symlink and have the sample overwrite the target. It now writes into a directory created for the run and opens the file with CreateNew. Both channel fixes are covered by tests proven to fail without them.

"localhost" resolves to ::1 before 127.0.0.1 on the CI agents, so the handshake was sent where nothing was listening and 26 tests failed. .NET surfaces a QUIC handshake that never completes as "Application layer protocol negotiation error", which pointed the investigation at ALPN rather than at the address the listener was bound to (dotnet/runtime#85412). The listeners now bind IPv6Any, which is dual stack and is what QuicTransportListener already does, so the harnesses match the deployment they stand in for. MismatchedAlpnListenerIsRefused had been passing for the wrong reason: it asserts that a connection is refused, and a connection that never arrives is also refused. Added a test that connects over IPv6 explicitly, because a host that resolves IPv4 first never exercises this and would let the same regression back in.

The transport was effectively untested in CI, and because the coverage report is merged from the ubuntu legs, all of Opc.Ua.Bindings.Quic counted as uncovered: 1314 of the 1600 uncovered changed lines the coverage gate was complaining about. Measured in a container on the same image family: without libmsquic 260 pass and 61 skip; with it 321 pass and none skip. The tests needed no changes to run on Linux, where QUIC mutual TLS is better supported than on Windows Server 2022 Schannel. A silent skip is the honest outcome where msquic is genuinely absent, but not on a machine that is supposed to have it - that is what hid this. The setup step sets UA_REQUIRE_QUIC, which turns the skip into a failure, so a future image or package change cannot quietly return the QUIC binding to zero coverage. Verified both ways: with the variable set and no msquic the suite reports 61 failures rather than 61 skips. The eleven copies of the skip check are now one shared helper.

SSH.NET 2025.1.0 carries a high severity path traversal: ScpClient.Download trusts the file and directory names the remote server sends during a recursive download, so a malicious or man-in-the-middle SCP server can escape the download directory and overwrite arbitrary files the client can write. SSH.NET arrives transitively through Testcontainers 4.13.0, which asks for [2025.1.0, ) and therefore resolves the lowest, vulnerable version. The patched 2026.0.0 satisfies that same range, so a central pin is enough and no consumer changes; transitive pinning is already enabled repository-wide. The pin should be removed once Testcontainers itself requires a fixed version. This is not part of the data channel work. The advisory was published while the branch was open and breaks master and every other open branch equally, but it blocks every check here, so it is fixed rather than waited on.

The prior whole-source substring assertion incorrectly rejected that metadata even though Objects.Thing retained its correct identifier 1. Parse the generated Objects.Thing initializer and require its exact identifier, with a second namespace URI containing 4242. Both cases pass with captured CI metadata and fail when claimed-sidecar isolation is deliberately reversed. No production or CI configuration changes. Validated the complete generator suite on net10.0 and net48: 264 passed on each, no failures or skips.

This guide describes the +implemented composition, not certification or an unqualified two-carrier result. + +Native QUIC and WebTransport data contexts do not require a UA SecureChannel, +Session, or AddressSpace. An application that also needs ordinary Client/Server +Services can explicitly enable the reserved Client/Server resource on either +native carrier. + +The lane uses the existing UACP/UASC and Client/Server implementations. It does +not start a TCP listener, forward traffic over loopback, or encode a second +Service protocol. Each common DATA payload carries exactly one complete UACP +MessageChunk, including HEL, ACK, OPN, MSG, CLO, or ERR. Normal UASC chunking, +security sequencing, request correlation, buffer ownership, and Session +processing remain in the existing stack. + +This implementation follows the OPC 10000-28 draft's optional native lane and +its OPC 10000-6 transport text, +`OPCF-Members/OPC10000-Core@673b3cfde6b2c8d6510d5b598dec1180c0add205`, +`source/data-channels/OPC-UA-Part6-Data-Channel-Transport.md`, +“Native peer binding and connection lifetime” and “Optional Client/Server lane.” + +## Independent opt-ins + +There are three separate choices: + +1.

This performs actual native TLS/mTLS and + profile confirmation, not UASC or Session establishment. +2. Optionally authorize and open a Client/Server lane using + `DataChannelClientServerClient` and `DataChannelClientServerListener`. +3. Independently enable the optional data-channel model and Session control + using `ServerDataChannelProvider` and the Server hosting APIs. + +Installing a lane service does not open a lane. Native-only Publisher/Subscriber +applications need neither the lane nor a Session. A configured native payload +flow can remain active while a lane on the same context opens or closes. + +## Security and resource policy + +Both peers must explicitly authorize this exact descriptor: + +| Field | Required value | +|---|---| +| ResourceUri | `urn:opcfoundation:ua:flow:resource:client-server:1` | +| Protocol | `urn:opcfoundation:ua:flow:payload:opaque:1` | +| Direction | Duplex | +| Delivery | Ordered | +| Protection | Confidential | +| AllowQueueExpiry | false | + +Other opaque resources are never interpreted as Services. + +The inner lane cannot create another Data Channel carrier or context. Client +and listener configuration reject flow profiles, reserved `/flow` resources and +nested context factories. The complete-chunk adapter rejects FLO on both send +and receive before passing bytes to UASC. This check applies only to the +reserved Client/Server lane, not to arbitrary opaque or PubSub payload bytes. +Registering a `ServerDataChannelProvider` for outer flows and optional Session +control does not inject it into the inner lane's listener settings. The server +supplies a context factory only to TCP/WSS listeners advertising an explicit +UASC Data Channel profile; the inner ordinary Service endpoint remains separate. + +The outer native connection remains confidential and mutually authenticated. +The inner SecureChannel has its own tokens, sequence numbers, policy and +reservations. This composition deliberately requires an inner `Sign` or +`SignAndEncrypt` policy and ordinary certificate-manager validation. In +addition, both inner application certificates must match the corresponding +native application's authenticated URI and SHA-256 SPKI identity. Trusting a +third application's certificate does not authorize it to forward a UASC +conversation through the native peer. + +`Sign` does not mean the native transport is unencrypted. Conversely, outer TLS +does not silently select an inner `None` policy. Discovery descriptions of a +native **data-only** endpoint must not be reused as the inner Service +description. + +## Client composition + +Keep the native connection alive while the lane is in use. Supply an explicit +virtual Service URL and ordinary UACP/UASC endpoint description. For example, +the native WebTransport CONNECT URL may be `opc.wt://host:4840/flow/v1` while +the configured inner Service URL is `opc.wt://host:4840/ua`. The latter is +selected by HEL inside the flow; it is not another HTTP CONNECT or socket. + +The following uses already initialized application configuration, certificate +managers, and a ready native connection: + +```csharp +using CertificateEntry own = + clientCertificates.AcquireApplicationCertificateBySecurityPolicy( + SecurityPolicies.Basic256Sha256) + ?? throw new InvalidOperationException("The application certificate is unavailable."); + +using Certificate peer = Certificate.FromRawData( + nativeConnection.NativeConnection.VerifiedPeerCertificateChain[0]); + +ServiceMessageContext messageContext = configuration.CreateMessageContext(); +var settings = new TransportChannelSettings +{ + Description = serviceEndpointDescription, + Configuration = EndpointConfiguration.Create(configuration), + ClientCertificate = own.Certificate, + ServerCertificate = peer, + CertificateValidator = clientCertificates, + Factory = messageContext.Factory, + NamespaceUris = messageContext.NamespaceUris +}; + +var lanes = new DataChannelClientServerClient(telemetry); +await using DataChannelClientServerConnection lane = await lanes.ConnectAsync( + nativeConnection.Context, + new Uri(serviceEndpointDescription.EndpointUrl), + settings, + cancellationToken); + +ISessionFactory sessions = new DefaultSessionFactory(telemetry) + .WithSubscriptionEngine(DefaultSubscriptionEngineFactory.Instance); + +using ISession session = sessions.Create( + lane.Services, + configuration, + new ConfiguredEndpoint(null, lane.Services.EndpointDescription, + lane.Services.EndpointConfiguration), + own.Certificate.AddRef()); + +await session.OpenAsync( + "Native Client/Server lane", 60000, userIdentity, [], + checkDomain: true, closeChannel: false, cancellationToken); + +// Use ordinary generated Session APIs: ReadAsync, CreateSubscriptionAsync, +// CreateMonitoredItemsAsync, PublishAsync, CallAsync, and others. + +await session.CloseAsync(10000, closeChannel: false, cancellationToken); +``` + +`serviceEndpointDescription` must describe the intended application, its real +certificate, its configured user-token policies, and its selected inner +security policy. Its transport profile is `Profiles.UaTcpTransport`, identifying +the ordinary virtual UACP/UASC stack, **not** the outer native data profile. +Its URL must exactly match the Service URL passed to `ConnectAsync`. + +The client's settings and certificate handles are borrowed during connection +establishment; the lane retains independent certificate references for its +own lifetime. + +## Server composition and routing + +Register the reserved resource with an explicit `IDataChannelSourcePolicy`, +alongside any independently authorized native resources. Inject the same +application-wide `DataChannelApplicationBudget` into the native binding and +the `ServerDataChannelProvider`. Use the provider as the native transport's +`IDataChannelContextFactory`. + +The provider is the **sole** consumer of each registered context's accept +queue. The listener consumes only its exact resource/protocol/carrier route: + +```csharp +var listener = new DataChannelClientServerListener( + DataChannelCarrierKind.WebTransport, + telemetry, + source: dataChannelProvider); + +var bindings = new DefaultTransportBindingRegistry(); +bindings.RegisterListenerFactory( + new DataChannelClientServerListenerFactory(listener)); + +server.TransportBindings = bindings; +server.UseDataChannels(dataChannelProvider, enableModel: false); + +// BaseAddresses contains one explicit virtual Service URL for this factory: +// opc.wt://host:4840/ua. Configure the ordinary signed policies and identities. +await server.StartAsync(serverConfiguration, cancellationToken); + +// Separately start/adopt the real native listener and accept native connections. +// Pass dataChannelProvider to that transport as its context factory. +``` + +The factory supplies its ordinary Service transport profile through +`ITransportListenerProfile`; it does not invent a native profile or change the +native data-only endpoint's discovery metadata. One factory serves one virtual +Service endpoint. A different listener/factory can serve the other carrier. + +For a standalone application that already owns routing, construct the listener +without a source, open it using `TransportListenerSettings` and the ordinary +`ITransportListenerCallback`, then pass an already routed flow: + +```csharp +await using DataChannelClientServerLane lane = + await listener.AcceptAsync(reservedFlow, cancellationToken); +``` + +Alternatively, `AcceptAsync(IDataChannelAcceptedFlowSource, CancellationToken)` +accepts one reserved lane from a shared router. Do not concurrently consume +`DataChannelContext.AcceptAsync` when a provider owns that queue. + +## Dependency injection + +The client can be resolved through `IDataChannelClientServerClient`: + +```csharp +services.AddOpcUa() + .AddDataChannelClientServer(new DataChannelClientServerOptions + { + MaxChunkSize = 32768, + MaxReceiveBytes = 262144, + MaxLanes = 16, + MaxPendingRequests = 128 + }) + .AddDataChannelClientServerListener(listener); +``` + +This registration preserves existing context factories and resource policies. +It does not register native credentials, load native images, start a native +listener, enable the model, or establish a Session. Those remain explicit +application decisions. Inject `IBufferManagerFactory`, `TimeProvider`, and +`ITelemetryContext` for client behavior; the direct listener constructor accepts +the same providers. + +## Limits and lifetime + +- Each lane reserves an independent flow and ordinary UASC admission resources. + Native connection/application limits still apply. +- Negotiated UACP chunk size is bounded by the admitted flow's payload size. + The common-record overhead is outside that payload. The default native + 65,536-byte record capacity therefore cannot carry a 65,536-byte UACP chunk. + A lane cannot operate below the UACP minimum of 8,192 bytes. +- Client lane count, listener lane count and outstanding client Service requests + have finite limits. The listener also reuses ordinary handshake deadlines, + connection admission, reassembly budgets and server resource isolation. + The client request limit includes Session keep-alive and background Publish + requests; leave capacity for those when selecting a lower limit. +- Closing or disposing a lane resets only its flow. Asynchronous disposal joins + native flow release and active writes; it never disposes the shared context. +- A standard Session may dispose its Service transport. The lane's + `DisposeAsync` remains the ownership join before the host tears down the + native connection. +- Cancelling an open or request does not abandon owned cleanup or retract a + secured, numbered chunk after commitment. +- Reconnection is explicit: create a newly authorized lane, then use the + ordinary Session reactivation APIs as appropriate. An old flow, security + sequence, or native context is never silently reused as a replacement. +- Stop/dispose the Server and its lane listeners before disposing the native + connections.

One `DataChannelApplicationBudget` shared across the +application bounds aggregate contexts, flows, bytes, messages, operations, grants, +probes and streams. `DataChannelOptions` bounds each context and flow, with an +injected `TimeProvider` for timers. Do not create a fresh application budget per +connection and expect an application-wide limit. + +For UASC, supply `TransportChannelSettings.DataChannels` and connect through +`UascDataChannelClient`. Its `UascDataChannelConnection` exposes the ready +`Context`; `Services` is available only for Shared UASC. Server hosting attaches +the provider through `UseDataChannels(provider, enableModel: false)` or the +`IOpcUaServerBuilder.AddDataChannels` and `AddDataChannelSource` extensions. +No provider means no flow endpoint. + +For native transport construction and deployment, see the +[QUIC binding](../src/Opc.Ua.Bindings.Quic/NugetREADME.md) and +[WebTransport binding](../src/Opc.Ua.Bindings.WebTransport/NugetREADME.md). +Native dependencies remain outside Core, ordinary Client/Server and base PubSub. + +### Complete-message I/O + +Once a channel is ready, application code uses the same facade for every carrier. +The following send assumes `flow`, a complete `ByteString payload` and a +`CancellationToken cancellationToken` supplied by the application: ```csharp -DataChannel channel = channels.Channels[0]; +DataChannelResult result = await flow.SendAsync( + payload, + cancellationToken: cancellationToken); +if (result != DataChannelResult.Good) +{ + throw new InvalidOperationException($"Data Channel send failed: {result}."); +} +``` -// Send.

Enforcing only the sending half would bound a well-behaved peer and leave a hostile one with an amplification surface, since PING is credit-exempt and compels a PONG ahead of queued payload | -| SequenceNumber budget, renewal threshold, stall-rather-than-reuse | Complete for the sender and the client-side renewal trigger; the `revisedLifetime` obligation of §5.1.1 is not implemented | -| `OpenDataChannel`, `ModifyDataChannel`, `CloseDataChannel` | Complete, and served by `StandardServer`: a real Client opens a channel through a real Session | -| Inline framing (`opc.tcp`, `opc.wss`) on the Server | Complete on the raw-socket `opc.tcp` listener. `InlineServerDataChannelTransport` resolves the UASC channel behind the request and enables the engine on it, so a Server with no transport configured still carries channels over the connection the Client already holds. A SecureChannel that can carry no frames is refused with `Bad_DataChannelTransportUnsupported` rather than accepted and then drained silently, which §5.16 requires | -| Authorization | Complete, and **direction-aware**: `SourceToSink` requires Read on the source, `SinkToSource` requires Write, `Bidirectional` requires both (Part 4 errata §7.2, DCS-023). Re-evaluated on an interval, on `ActivateSession` and on role change | -| Parameter negotiation, Session scoping, authorization recheck, audit | Complete, and driven from the Server. **Server-initiated offers (Part 4 §6) are not implemented**: the registry exists but nothing creates an offer or raises `DataChannelOfferedEventType`, so `TryRedeem` can only fail | -| `opc.quic` — url scheme, ALPN negotiation and enforcement, control stream, client channel and factory | Complete (`Opc.Ua.Bindings.Quic`, **net8.0+**) | -| `opc.quic` — listener, service host, endpoint discovery, reverse connect, certificate rotation | Complete | -| `opc.quic` — data channels bound to per-channel streams, `RESET_STREAM` carrying the StatusCode | Complete. The stream is released when the channel reaches a terminal state, so an orderly close completes the writes and a `RESET` becomes a `RESET_STREAM` carrying the StatusCode | -| `opc.quic` — direction to stream type and initiator (§7.4), `revisedTransportChannelId` | Complete; `SourceToSink` gets a server-initiated unidirectional stream whose id is returned to the Client | -| `opc.quic` — TLS-to-OPC-UA key binding (§7.6.1) | Complete. The binding is verified on the connect path, comparing the TLS peer's subjectPublicKeyInfo against the OPN senderCertificate in constant time | -| `DataChannelCapabilities` model projection | **Not wired.** `DataChannelModel` builds the values, but the Object is never instantiated under `ServerCapabilities`, so a Client cannot read the capabilities or discover the feature through the address space (Part 3 §6, Part 4 §10) | -| Worked samples | `samples/Core/ConsoleDataChannelStreaming` (throughput benchmark) and `samples/Core/ConsoleDataChannelAudio` (looping audio, played back by the Client) | -| Unreliable datagrams (§7.5) | **Not implementable on .NET.** `QuicConnection` exposes no RFC 9221 datagram API through .NET 10, so `SupportsUnreliableDatagrams` is `False` and the Server refuses `Unreliable` and `PartiallyReliable` with `Bad_DeliveryModeUnsupported` — which is what the errata requires rather than silently carrying them on the stream | -| DI / fluent builder extension | Complete. `AddQuicTransport()` registers the listener and channel factories **and** the server-side data channel transport, so a DI-built Server carries channels on `opc.quic` streams with no further wiring. `UseQuicDataChannelTransport()` is the direct-construction fallback | -| Connection loss and SecureChannel close | Complete. A closed SecureChannel or lost transport faults every data channel riding on it (§5.13), on both the inline and `opc.quic` paths | - -## Why the QUIC binding is net8.0+ - -`System.Net.Quic` carries `[RequiresPreviewFeatures]` on net8.0, so the binding enables -preview features for that target and a net8.0 consumer sets `EnablePreviewFeatures` in -its own project to use it. On net9.0 and net10.0 the API is stable and no opt-in applies. -`QuicServerConnectionOptions.HandshakeTimeout` is .NET 9+, so on net8.0 the platform -default bounds the handshake and the listener's own admission expiry still releases a -stalled peer's slot. `Opc.Ua.Core` is unaffected and builds for all six TFMs. - -## Running the sample - -### Audio streaming - -`samples/Core/ConsoleDataChannelAudio` is the shortest path to seeing the feature do -something a Subscription cannot. It stands up a Server and a Client in one process, -synthesises a short melody as 16-bit PCM, and streams it on repeat over a data channel -while the Client plays it: - -```sh -cd samples/Core/ConsoleDataChannelAudio -dotnet run # 20 ms frames -dotnet run -- 60 # 60 ms frames -``` - -The source writes in real time rather than as fast as the channel will take it, because a -media source is paced by its own clock and writing faster would only add latency. The -progress line reports frames, bytes and credit stalls, so a consumer that cannot keep up -is visible rather than silently buffered. - -Playback uses NAudio, whose output devices are Windows interfaces; on Linux and macOS the -sample writes the received stream to a WAV in the temp directory instead and says so on -startup. +`null` means directional EOF, not a reset or authorization success fallback. +Disposal releases both byte and message-count capacity. Do not retain payload +memory after disposing its message. `EndAsync` drains the local sending direction; +the other direction of a duplex flow can continue. Observe its result and the +peer's EOF before reporting orderly completion. `ResetAsync` and asynchronous +disposal join flow resource release without closing unrelated flows. + +`Parameters`, `GetStatus`, `GetDiagnostics` and `StateChanged` expose the admitted +descriptor, outcomes and lifecycle. `UpdateAsync` performs the revision transaction; +changing a local descriptor object is not a negotiated update. A repeated +operation uses the same nonzero operation ID and proposal. A committed update +cannot be rolled back by caller cancellation. + +### Connection and Session ownership + +A flow borrows its `Context`; owning one flow does not authorize disposing the +association used by other flows. The UASC connection or native transport owner +owns that association. + +To create a Session on Shared UASC, use the ordinary session factory's +transport-taking `Create` overload with `connection.Services`, then open the +Session. A configuration-only `CreateAsync` opens another transport and does not +demonstrate sharing. The samples check transport identity and SecureChannel IDs +as well as actual Read/Publish traffic. + +Finish the flows before disposing their transport. When closing only a shared +Session, use `CloseAsync(..., closeChannel: false)`; its later disposal still owns +the supplied transport. The samples close the Session, close the connection, +then dispose the Session. Certificate handles passed to transport settings are +owning handles: use independent `AddRef()` handles when retaining the originals, +and release handles not transferred during failed establishment. + +After native WebTransport ingress is attached, readiness failures retain the +HTTP/3 or CONNECT rejection instead of being masked by the transport's close +token. Caller cancellation and the configured establishment deadline remain +independent. + +## Optional model and Session authorization + +Configured authorization uses an explicit `IDataChannelAuthorizer` on both peers. +Server applications can register exact resources and an `IDataChannelSourcePolicy` +with `DataChannelSourceRegistry` and `ServerDataChannelProvider`. Unknown resources +are denied. Configured flows do not become dependent on Sessions merely because +the application also exposes an ordinary server. + +The independently enabled model provides the generated manager, sources, +capabilities, offers, events and per-Session diagnostics. The manager's +`OpenDataChannel`, `ModifyDataChannel` and `CloseDataChannel` are **Methods invoked +through normal Call**, not request/response Service types. + +`DataChannelSessionControl` uses the generated manager proxy. Given an ordinary +Session, a `SessionDataChannelAuthorizer` wrapping the local resource policy and +the same clock used by that authorizer: -### Throughput benchmark - -```sh -cd samples/Core/ConsoleDataChannelStreaming -dotnet run -- --transport tcp --mode server --frames 2000 --size 1200 -dotnet run -- --transport quic --mode server --frames 2000 --size 1200 +```csharp +var control = new DataChannelSessionControl(session, authorizer, clock); +DataChannel flow = await control.OpenAsync( + context, sourceNodeId, parameters, cancellationToken); ``` -`--mode server` is the one that matters: it stands up a real `StandardServer`, -connects a real Client, creates a Session, and opens the channel through -`OpenDataChannel` — so it exercises the Service dispatch, the Session binding and -the negotiation, not just the framing. `--mode direct` drives `DataChannelManager` -directly and is kept because that is the shorter path for measuring the scheduler. - -The same application code drives both framings; only the transport differs. The -sample reports throughput, discarded frames and the credit-stall counter, and the -stall counter staying at zero over `opc.quic` is the visible consequence of QUIC -owning the flow control there. - -## Measuring throughput against a competing Publish load - -`--mode benchmark` answers a narrower question: what does a data channel sustain -while the Session is also carrying Service traffic? It runs four cases — no -subscription, then monitored items publishing at 10 ms, 100 ms and 1000 ms — for -the transport given by `--transport`, and prints them as one table. - -```sh -dotnet run -- --transport tcp --mode benchmark --frames 60000 --size 1200 \ - --monitored-items 100 --repeat 5 -dotnet run -- --transport quic --mode benchmark --frames 60000 --size 1200 \ - --monitored-items 100 --repeat 5 +The helper reserves an ID, obtains and validates the single-use grant, and waits +for actual flow readiness. Both peers still enforce resource policy. Session +permissions are additional checks, not replaced by application policy. +`control.ModifyAsync` stages the complete update through Call and waits for its +data-path outcome; the Call response alone is not a committed revision. + +Grants are bound to the authenticated context, peer, challenges and ChannelId. +They do not carry an AuthenticationToken or private key. A disconnected control +transport is not a closed Session. Session expiry, closure or revoked +identity/permission invalidates its grants and dependent flows; configured +neighbours remain independent. Context loss invalidates all flows on that context. +Reconnect requires fresh context identity, IDs and authorization. + +The provider owns one accepted-flow router. Consumers select their exact +resource/protocol/carrier through that router; they must not race separate +`Context.AcceptAsync` calls against it. + +## PubSub over the flow + +The adapter in `Opc.Ua.PubSub.Transports.DataChannels` implements the existing +`IPubSubTransportFactory` / `IPubSubTransport` contracts. It reuses Part 14 +**1.05.06** writers, readers, metadata, diagnostics, encoders and security. +This feature does not upgrade the Part 14 version. + +Configure the connection with `DataChannelPubSubConfiguration.Configure` or +`PubSubConnectionBuilder.WithDataChannel`. Register the provider using +`PubSubApplicationBuilder.UseDataChannelTransport` or +`IPubSubBuilder.AddDataChannelTransport`. See the +[configuration example](../src/Opc.Ua.PubSub/NugetREADME.md#brokerless-datachannel-transport) +and [PubSub guide](PubSub.md#data-channels-experimental). + +The negotiated payload protocol selects UADP or JSON; the carrier URI cannot +choose the encoding. One complete encoded NetworkMessage is one flow payload, +with every byte preserved. ChannelId never replaces PublisherId, WriterGroupId +or DataSetWriterId. Multiple writers can share an authorized flow; different +resource permissions, delivery contracts or lifetimes need separate flows. + +The PubSub adapter rejects `AllowQueueExpiry=true`. Dropping a key frame or +metadata can invalidate later messages, so enabling expiry requires a +Publisher-side dependency and recovery policy that this adapter does not yet +provide. It neither silently clears the option nor parses or rewrites payloads +to simulate recovery. Default no-expiry UADP and JSON delivery is unchanged. + +Carrier encryption is independent of optional Part 14 message security. +SecureChannel protection alone requires no broker or SKS. Existing UADP +signing/encryption remains available through its normal key provider; JSON does +not silently satisfy a UADP message-security requirement. + +## Optional native Client/Server lane + +Native configured flows do not create UASC or Sessions. An application can +explicitly select `DataChannelProfiles.ClientServerResource` for an ordered, +duplex, confidential, opaque flow with no queue expiry. The common byte adapter +carries one complete UACP/UASC chunk per DATA message and reuses ordinary +Client/Server dispatch inside it. + +The lane, optional model and Session authorization are separate choices. See +[Client/Server lane integration](DataChannelClientServer.md) for direct and DI +composition and its native prerequisites. Do not start competing accepted-flow +readers when hosting the lane beside PubSub or other resources. + +## Wire and resource boundaries + +The common record has a 13-byte header and either opaque DATA or binary CONTROL. +CONTROL uses opcodes `0..14`, ordered little-endian fields, OPC UA Binary Guid +layout, strict length-prefixed UTF-8 strings, and an exactly 32-byte challenge. +Booleans are `0` or `1`; rates must be finite and nonnegative, with both zero +representations treated as unlimited for ordered delivery. Datagram rates must +be strictly positive. A Configured OPEN has no grant bytes; +a Session OPEN has exactly one Guid. There is no JSON CONTROL fallback. + +Both dedicated and shared UASC use `FLOF`, RequestId zero, and a four-byte +ChannelId followed by exactly one common record. Dedicated UASC admits only +management zero and DATA one, never ordinary MSG Services or CREDIT. Native +datagrams also carry an external ChannelId. +The runtime rejects malformed framing, noncanonical control values, invalid +association/stream ownership and premature application data; applications do +not implement a second parser. + +Shared FLO credit starts at zero and counts encoded flow bytes. Both UASC +carriers and native datagrams have 17 bytes of DATA overhead; native ordered +streams have 13. Native ordered flows backpressure at the record header before +allocating the body. Physical UASC ingress reserves a bounded context/application +queue and waits at most `DrainTimeout` for DATA queue capacity. If the application +does not drain it, the affected flow fails instead of indefinitely preventing +later management processing. Native datagrams +have finite admission, rate and replay budgets rather than stream-credit +semantics. + +Native parser staging, incomplete records, queued messages and application-held +leases share one application budget. DATA queue handoff transfers the existing +ingress allocation and reservation; control admission covers overlapping encoded +and decoded-value storage. Both new revision directions stay reserved until +their directional barriers complete, and retained old messages keep their old +revision charged. + +Each context withholds **512 bytes and four message slots** for fixed-field +management/control progress, including a directional revision exchange and its +CREDIT/ACK replies. DATA and generic carrier allocations cannot borrow this +headroom. Unused headroom is not reported as retained `BufferedBytes` or +`Messages`; it returns when the context closes. Larger establishment controls +still need additional application admission. Native streams also reserve their +two 13-byte parser staging areas before allocation. + +UASC flow chunks are final chunks and use the same per-sender security sequence +as MSG/OPN/CLO. Numbering and writer admission remain atomic. The unsealed writer +selects a pending control after at most eight consecutive Service messages; +Services remain ahead of DATA. Already numbered or in-flight writes, including +coalesced writes, cannot be reordered. FLO CONTROL on opc.wss is binary +application data, not an RFC6455 control frame. These policies imply no +wall-clock latency or one-frame Service-delay guarantee. +Benchmark results include their actual load, pacing and loopback setup; +numbers from the discarded framing are not evidence for this protocol. + +## Native deployment + +The optional native bindings target .NET 8 or newer. Native execution qualification +uses .NET 10 on Windows x64 and glibc Linux x64. The backend packages and their +deployment contracts are: + +- [Native.QuicGo](../src/Opc.Ua.Native.QuicGo/NugetREADME.md): pinned quic-go, + mutual-authentication and confirmed-handshake evidence, real datagrams and + reliable-reset observation.

Thus the default descriptor is **AcceptorToOpener**. `--publisher client` +selects **OpenerToAcceptor** without changing connection initiation. This is payload +role reversal, not reverse-transport UASC, whose ambiguous shared combination is +not offered by the sample. + +All messages use Ordered delivery, Confidential protection, no queue expiry, one +exact opaque resource and explicit finite bounds. `--size` accepts 4–32768 bytes. +The first four bytes are a little-endian sample counter, not an OPC UA payload +standard. Every received byte and decoded counter is checked. A transient +`WouldBlock` send or `END` result is retried through the same public facade under +the finite deadline; it is not treated as successful delivery or a reason to +discard/reframe data. + +`--revise` changes priority halfway through the messages. It waits until the first +half has arrived, then uses the opener's actual revision transaction and requires +revision 2 on both peers. In Session mode the generated control helper stages the +proposal using `Call`; the data-path ACK, not the Call response, completes it. +Dedicated/native Session mode explicitly opens a **separate ordinary TCP control +connection**. Configured dedicated/native mode creates no Session and needs no model. + +## Native QUIC and WebTransport prerequisites + +**The current native acceptance gate is blocked.** The managed native loader now +requires ABI 4, while the last completed sample checkpoint below used a coherent +ABI 3 closure. A qualified matching ABI 4 closure and resolution of WebTransport's +peer-STOP/minimum-reliable-header requirement are still required. Do not reuse an +old ABI 3 runtime as a fallback or treat the historical passing sample runs as +proof that this newer transport-conformance gate is satisfied. + +Native modes require matching reviewed **Windows x64 or Linux x64** assets and the optional +binding dependencies. The generic QUIC backend must expose +the strict ABI required by the matching managed loader (**currently ABI 4**), +including actual reset/peer-STOP observation and verified mutual-authentication +evidence. Older ABIs are intentionally rejected; do not mix an old native image +with the current managed binding. WebTransport additionally needs +the matching native HTTP/3 **draft-16** implementation. BCL QUIC, WSS, Kestrel +draft-02 and browser WebTransport are not substitutes. + +Select assets through these environment variables, or equivalent command-line +options: + +| Environment variable | Required value | +| --- | --- | +| `OPCUA_QUIC_LIBRARY` | Absolute path to the independently reviewed `opcua_quic_go.dll` or `libopcua_quic_go.so` | +| `OPCUA_QUIC_SHA256` | Expected 64-hex SHA-256 from the deployment/review receipt | +| `OPCUA_HTTP3_LIBRARY` | Absolute path to the reviewed `opcua_http3.dll` or `libopcua_http3.so` | +| `OPCUA_HTTP3_SHA256` | Expected HTTP/3 image SHA-256 from that receipt | + +The native CI fixture names are accepted aliases: `OPCUA_QUIC_NATIVE_PATH`, +`OPCUA_QUIC_NATIVE_SHA256`, `OPCUA_HTTP3_NATIVE_PATH` and +`OPCUA_HTTP3_NATIVE_SHA256`. Expected hashes are required in addition to paths; +there is no implicit trust of whichever binary happens to exist. + +Do not derive a trusted expected hash from an arbitrary file being loaded. +The sample does not search `PATH`, download assets, accept an unknown certificate, +or silently change carrier. Missing assets, unsupported platform/key capability, +hash mismatch or handshake failure produce a nonzero exit. + +With those explicit deployment inputs already set: + +```powershell +if (!(Test-Path $env:OPCUA_QUIC_LIBRARY)) { throw 'Select the reviewed QUIC asset first.' } +dotnet run --project samples\Core\ConsoleDataChannelStreaming --no-build --no-restore -- --carrier quic --count 8 --size 64 --revise + +if (!(Test-Path $env:OPCUA_HTTP3_LIBRARY)) { throw 'Select the reviewed draft-16 HTTP/3 asset first.' } +dotnet run --project samples\Core\ConsoleDataChannelStreaming --no-build --no-restore -- --carrier webtransport --count 8 --size 64 --revise + +# Native payload role reversal and independently selected ordinary Session authorization. +dotnet run --project samples\Core\ConsoleDataChannelStreaming --no-build --no-restore -- --carrier quic --publisher client --count 8 --size 64 --revise +dotnet run --project samples\Core\ConsoleDataChannelStreaming --no-build --no-restore -- --carrier webtransport --authorization session --count 8 --size 64 --revise +``` + +Native configured modes use mTLS directly, with no implicit UASC or Client/Server +lane. WebTransport explicitly permits **absent Origin only** and authorizes the +exact loopback CONNECT endpoint and authenticated peer. The library performs +SETTINGS, CONNECT, stream association and protected HELLO. + +The certificate-manager native bridge currently requires an exportable software +application key. HSM/non-exportable keys unsupported by that ABI are refused; +there is no raw-PFX, system-trust or alternate-key fallback. + +## Trust, measurements and cleanup + +Each run creates two owned application identities using `ApplicationInstance`, +certificate managers/stores and a random password held by the secret provider. +Each manager trusts only the other application's public certificate. Resource +policies separately pin the peer application URI and public-key SHA-256, payload +direction, content type, bounds and selected authorization mode. Session control +uses the client certificate as an explicitly trusted X.509 user identity. + +State is created in a fresh repository-local directory and removed on normal +completion, failure or cooperative cancellation. `--state NEW-DIRECTORY` selects +that owned directory explicitly; an existing path is refused. Keys and passwords +are never embedded in code or printed. + +Success produces one `SUMMARY` JSON line **after cleanup**: + +- exact message/byte counts, independent sent/received SHA-256 and committed revision; +- actual ContextId, flow ChannelId and UASC SecureChannelId; +- ordinary Service SecureChannelId plus transport-reference equality in shared mode; +- real server Session/Read/Publish/Call counters and decoded notification counts; +- first-send through directional-EOF time and measured received-payload throughput; +- zero application budget/native ownership evidence. + +Benchmark lines are separate `BENCHMARK` records for unloaded/loaded runs. Each +run uses a fresh authenticated connection; setup time is excluded. A loaded run +with no completed competing Read/Publish cycle is rejected, not advertised as a +successful scheduling measurement. Increase count/pacing for such a run. +These loopback numbers include application verification and any requested pacing; +they make **no one-frame Service-latency claim**. + +## Acceptance tests and validation status + +The process tests run the actual executables, compare known exact bytes, check +Session/model independence and real shared-channel identities, parse finalized +WAV data, exercise refusal/cancellation, and rebind released ports. + +```powershell +dotnet test tests\Opc.Ua.DataChannel.Samples.Tests\Opc.Ua.DataChannel.Samples.Tests.csproj -f net10.0 --filter 'TestCategory!=NativeDataChannelSamples' +# Requires the reviewed native asset environment variables above; missing assets fail, never skip. +dotnet test tests\Opc.Ua.DataChannel.Samples.Tests\Opc.Ua.DataChannel.Samples.Tests.csproj -f net10.0 --filter 'TestCategory=NativeDataChannelSamples' +``` + +Historical **ABI 3 integration checkpoint**, preceding the blocked ABI 4 gate, +verified independently on **Windows x64 and Linux x64/.NET 10**: +**53 passed, +0 failed, 0 skipped on each platform**, covering all four real carriers, both payload +roles, configured/Session control, live revision, actual shared Read/Publish traffic, +headless WAV output, rejection and cancellation/cleanup. Separate finite Windows +CLI runs also completed for every carrier. Actual Windows playback completed a +200 ms run and drained the device. Earlier ABI 2 receipts are retained separately +as historical evidence, not reused for this checkpoint. A correctly hashed ABI 2 +image was also explicitly refused by the current executable with a nonzero exit, +no listener and no success summary. + +The coherent ABI 3 runs used the matching Core/QUIC/WebTransport managed outputs +and these independently supplied native-image hashes: + +| Asset | Windows x64 SHA-256 | Linux x64 SHA-256 | +| --- | --- | --- | +| QUIC ABI 3 | `1027ed447b30c1447595df907fc081ed797f0ee4f2536ed4d16374274e5780a8` | `764e401b8280d384d401c9367e3186b9d73ea2d004418ffeb19e7c830929a726` | +| HTTP/3 draft-16 | `e4d27eef05b32727d6946b197ba504b852e4a92e1538447a6554b968dc941c49` | `3da96b4a830be760e2fa3589844b6495208b471e5cb99698899cdcb0578aa8ff` | + +This is historical sample integration evidence for that candidate closure, +**not current whole-carrier/lane conformance or approval of a final native +distribution**, signing/SBOM or NativeAOT package gate. In particular, the later +peer-STOP/minimum-header regression is not covered by those passing receipts. + +Linux acceptance executed the portable managed outputs, not just a cross-build. +The bounded runner below uses the already cached qualified public SDK 10.0.401 +image. It never pulls an image, restores packages, builds a repository mirror or +installs a native toolchain. Point the four environment variables at the reviewed +**Linux ELF assets on the host**, then run: + +```powershell +.\tests\Opc.Ua.DataChannel.Samples.Tests\Test-NativeLinux.ps1 ` + -QuicLibrary $env:OPCUA_QUIC_NATIVE_PATH -QuicSha256 $env:OPCUA_QUIC_NATIVE_SHA256 ` + -Http3Library $env:OPCUA_HTTP3_NATIVE_PATH -Http3Sha256 $env:OPCUA_HTTP3_NATIVE_SHA256 ` + -ResultsDirectory .git\testagent\dc-samples\linux-validation +``` + +Build the portable sample/test outputs and restore the existing centralized +`coverlet.collector` reference first. Results must name a new or empty directory: +stale reports cannot satisfy acceptance. The runner copies only portable output +closures, the existing collector and native assets (about 85 MiB in the verified +run), limits the container to two CPUs/2 GiB/240 seconds, uses no external network, +and removes its exact container and staging directory.

The private-key password is +random and process-local, backed by the existing secret store. Owned demo PKI +is deleted during cleanup. The default flow uses +`/flow/v1/dedicated`, confidential protection, and the exact +`DataChannelProfiles.DedicatedUasc` profile. It creates **no Session**, installs +**no DataChannel address-space model**, and sends **no ordinary Services**. + +The production transport performs HEL/ACK/OPN and protected context/flow +establishment.

Cancellation, invalid options, mismatched decoded values, failed +authorization, and failed teardown return a nonzero exit code. There is no +alternate-transport fallback. + +## What it demonstrates + +- Two ordinary PublishedDataSets, one WriterGroup (`7`), two DataSetWriters + (`101`, `202`), and a stable UInt16 PublisherId (`42`). The fields are Int32 + `Counter`, Boolean `Toggle`, and Double `Temperature`, with metadata version + `1.0`. The two readers receive distinct, changing values. Unmatched + PublisherId and DataSetWriterId readers receive nothing. +- UADP and JSON use the existing standard encoders, metadata registry, writers, + readers and sinks. A complete encoded NetworkMessage is a complete flow + payload. There is no new NetworkMessage wrapper, flow-ID substitution, + custom encoder, or decode/re-encode bridge. JSON has no UADP numeric + WriterGroupId header; the sample does not invent one. +- The existing metadata publisher's announcements are retained, so the total + NetworkMessage count can exceed `--count`. Finite progress observes the + standard WriterGroup's completed data publishing cycles, not raw packet + counts. Exact byte comparison includes metadata announcements too. +- Half the real messages cross revision 1. The opener then reduces + `MaxMessageSize` from 32768 to 16384 and `MaxReceiveBytes` from 262144 to + 131072 through the library transaction. The remaining messages cross + committed revision 2 on the same flow. Both peers perform orderly END and + cleanup. +- By default, the **server publishes while the client initiates the transport + and opens the flow** (`AcceptorToOpener`). With `--reverse`, the client + publishes (`OpenerToAcceptor`). Publisher, transport initiator and flow opener + are separate roles. This is not transport reverse-connect. +- `--shared` constructs the actual Session on + `UascDataChannelConnection.Services`, not a second service socket. While the + PubSub flow is live, it reads server time and receives changing monitored + notifications through ordinary Publish. The summary and evidence expose + actual SecureChannel/context identifiers, same-transport identity, and + client/server service counters. Client counters cover the explicit probe; + server Session counters also include initialization Reads. +- `--authorization session` uses a certificate-authenticated ordinary Session, + the generated manager proxy and normal Call service to acquire a fresh, + context/peer/challenge-bound grant. The local Session authorizer and server + source policy both validate admission. The Session route also stages its + revision through the generated proxy. Dedicated mode uses a separate + ordinary `/control` endpoint; Services are never sent to its flow endpoint. + The optional model is installed only for this authorization mode. + +Both peers independently allow-list the exact resource, protocol, direction, +protection, limits, expected application URI and peer public key. The server +additionally restricts Session authorization to its configured X.509 caller; +there is no anonymous grant bypass. UASC protects confidentiality, so this +sample does not require an SKS or introduce extra Part 14 message-security keys. + +Certificate wrappers supplied to `TransportChannelSettings` are independent +`AddRef()` handles: the transport owns them, not the manager's borrowed handles. +Failed connection attempts release any untransferred handles. Shared teardown +finishes the flows, checks `Session.CloseAsync(..., closeChannel: false)`, closes +the owning connection, then disposes the Session. Disposal cannot turn a failed +close into a successful sample result. + +## Separate processes + +Build once. Choose a fresh PKI directory and readiness filename. The same +private-key password must be supplied privately to setup and both processes; +the sample resolves it through the secret-store-backed certificate password +provider. It is never a command-line argument, source constant, or report field. + +```powershell +dotnet build samples\PubSub\ConsoleSecureChannelPubSub --property:CustomTestTarget=net10.0 +$app = "samples\PubSub\ConsoleSecureChannelPubSub\bin\Debug\net10.0\ConsoleSecureChannelPubSub.dll" + +# Example provisioning input; use an appropriately protected secret source in deployment. +$env:OPCUA_SAMPLE_KEY_PASSWORD = [Convert]::ToBase64String( + [System.Security.Cryptography.RandomNumberGenerator]::GetBytes(32)) +dotnet $app setup --pki .git\testagent\pubsub-pki +``` + +In a server terminal with that same environment secret: + +```powershell +$app = "samples\PubSub\ConsoleSecureChannelPubSub\bin\Debug\net10.0\ConsoleSecureChannelPubSub.dll" +dotnet $app server --pki .git\testagent\pubsub-pki --ready .git\testagent\pubsub-ready.json --count 8 --result .git\testagent\pubsub-server.json +``` + +In a client terminal with that same environment secret: + +```powershell +$app = "samples\PubSub\ConsoleSecureChannelPubSub\bin\Debug\net10.0\ConsoleSecureChannelPubSub.dll" +dotnet $app client --pki .git\testagent\pubsub-pki --ready .git\testagent\pubsub-ready.json --count 8 --result .git\testagent\pubsub-client.json +``` + +The client waits for the atomic readiness file written only after the real +listener starts. An automatically selected loopback port is the default; +`server --port 48420` selects a fixed data port. Both processes must agree on +`--shared`, `--encoding`, `--authorization`, `--reverse`, and `--count`. +Use a fresh readiness filename on the next run. Setup refuses to overwrite an +existing identity/trust directory. Process-mode PKI is retained for explicit +reuse; delete only that owned directory when finished and clear the environment +secret. Missing state or an incorrect password is an actionable error, not a +reason to create a new identity or accept an arbitrary certificate. + +## Real-process tests and byte evidence + +```powershell +dotnet test tests\Opc.Ua.PubSub.Samples.Tests --framework net10.0 --property:CustomTestTarget=net10.0 +``` + +The tests launch the compiled sample in both single- and two-process modes, +covering both codecs, carriers, authorization routes and application roles. +They compare **every byte of every actual successful transport send** with +the corresponding complete receive, independently of decoded-value assertions. +The diagnostic decorator forwards the real transport's encoding/limit +capabilities and yields its original receive frames without changing lease +ownership. It does not inspect Core records or implement READY/credit. +Reports also retain per-message revisions, decoded changing values and service +counters. Setup, invalid-option and finite-deadline cases exercise owned PKI +cleanup and real listener release. + +This sample is deliberately UASC-only. It makes no claim about native QUIC, +WebTransport or unresolved transport reverse-connect combinations. diff --git a/samples/PubSub/ConsoleSecureChannelPubSub/SampleAuthorization.cs b/samples/PubSub/ConsoleSecureChannelPubSub/SampleAuthorization.cs new file mode 100644 index 0000000000..91e0197d7c --- /dev/null +++ b/samples/PubSub/ConsoleSecureChannelPubSub/SampleAuthorization.cs @@ -0,0 +1,137 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

Registration does not start listeners, install +Service transport factories, or advertise endpoints. Hosts with optional +model/control routing can register their `IDataChannelContextFactory` instead of +the direct common factory. + +Discovery uses `DataChannelProfiles.Quic`. Native discovery descriptors use +SecurityPolicy `None` and MessageSecurityMode `None` to indicate **no UASC**, +not unprotected transport. They must still identify the actual TLS application +certificate. An `opc.quic` data endpoint is not an ordinary discovery endpoint. + +## Native credential and lifetime helpers + +`Opc.Ua.Bindings.Native` contains reusable `NativeQuicCertificateProvider`, +`NativeQuicListener`, `NativeQuicConnection` and `NativeQuicStream`. They have no +flow, Session or HTTP/3 framing requirement and can also host the optional +WebTransport binding. + +Credentials are explicit DER leaf/intermediates, trusted roots, application URI, +peer URI/SPKI rules and software PKCS8 signing material. The native signer supports exportable +RSA2048..4096 and ECDSA P256/P384/P521. Non-exportable/hardware keys and unsupported +curves are refused, not silently substituted. Exported key buffers are cleared +after native listener/connect creation completes. + +The native engine checks chain, validity, EKU, hostname and peer pins. The bridge +also awaits the stack certificate manager's validation, including its configured +revocation policy. Selected certificate/trust/CRL changes invalidate affected +associations; periodic revalidation and certificate expiry bound their lifetime. +A selected certificate replacement conservatively requires a fresh native +association, including a same-key reissue. Unrelated trust scopes do not revoke it. + +Native completion results retain accepted byte counts and racing cancellation +outcomes. A committed flow write retains its input until the real native result +is drained. Close wakes native I/O, drains pending operations, releases streams, +then releases the connection. A blocked native datagram send can close its +connection on failure; that actual context loss is propagated. + +Peer RESET and STOP are observed independently of a backpressured application +reader or an earlier local reset, using actual received native frames rather +than a fabricated EOF or local cancellation cause. The binding +requires native ABI4 (operation revision3); older libraries are refused before +opening a listener or connection. High-level connection `Completion` also waits +for ingress and its reserved host capacity to drain. + +The raw helper reports reset frame type, final size and reliable size exactly as +sent. Generic QUIC permits an ordinary RESET_STREAM in response to peer +STOP_SENDING, including after an earlier reliable reset. Such evidence is not +automatically sufficient for a higher-level protocol's reliable-prefix policy; +the WebTransport binding must enforce its additional requirements independently. + +## Bounds and platform scope + +`QuicDataChannelOptions` and `NativeQuicConnectionSettings` bound stream handles, +unbound-stream lifetime, anti-reuse history, record size, operations and +establishment/recheck deadlines. The common application budget independently +bounds contexts, flows, messages, bytes and control operations. Backend global +limits also apply; they are not replaced by larger application settings. + +Management uses the actual first initiator-created bidirectional stream. A +common OPEN on each new flow stream makes it physically observable before +ACCEPT/READY. Association requires the actual connection-owned handle and +correct stream identifier, direction and opener. There is no extra QUIC flow +header, fabricated stream ID or empty-write/FIN announcement workaround. + +Supported managed targets are .NET 8, 9 and 10; legacy solution matrix legs are +inert and do not claim native .NET Framework support. Native assets are currently +win-x64 and glibc linux-x64. No musl, ARM or macOS support is implied. +The Go native image is process-lifetime and must not be unloaded. Asset loading +checks the selected path, SHA256 receipt and ABI. Packaging requires the backend's +`NativeQuicAssetRoot`; no native binary or test credential belongs in source. + +See the native backend's `NATIVE_ABI.md` for asset prerequisites and production +signing, per-RID security/SBOM and minimum-host acceptance requirements. A source +build or backend test alone is not whole-product distribution approval. diff --git a/src/Opc.Ua.Bindings.Quic/Opc.Ua.Bindings.Quic.csproj b/src/Opc.Ua.Bindings.Quic/Opc.Ua.Bindings.Quic.csproj index baea18a29b..53445750cb 100644 --- a/src/Opc.Ua.Bindings.Quic/Opc.Ua.Bindings.Quic.csproj +++ b/src/Opc.Ua.Bindings.Quic/Opc.Ua.Bindings.Quic.csproj @@ -1,13 +1,6 @@ - + net8.0;net9.0;net10.0 $(CustomTestTarget) $(LibCoreTargetFrameworks) @@ -15,29 +8,22 @@ $(AssemblyPrefix).Bindings.Quic $(PackagePrefix).Opc.Ua.Bindings.Quic Opc.Ua.Bindings - Experimental OPC UA QUIC Binding Library.

Older native images are refused, not assigned +synthetic capabilities. ABI4's truthful observations do not resolve the +minimum-header limitation above. + +The application supplies `INativeQuicBackend`, `INativeQuicCredentialProvider`, +`NativeHttp3Library`, `IDataChannelContextFactory`, one shared +`DataChannelApplicationBudget`, and explicit `WebTransportDataChannelOptions`. +The certificate provider in `Opc.Ua.Bindings.Native` reuses the stack certificate +manager, secret stores, trust validation and rotation.

Use `DataChannelDeliveryMode.Datagram` only when the +resource policy explicitly admits genuinely unreliable application datagrams. + +Native endpoint discovery can use SecurityMode None / SecurityPolicy None to +describe the absence of a UASC envelope. It does **not** mean unprotected traffic: +confirmed TLS 1.3 mutual application authentication and exact expected keys +remain mandatory. + +One CONNECT/session and one application pair are permitted per fresh connection. +No pooling, resumption, 0-RTT, redirects or retry on a rejected/closed CONNECT is +performed. Listener disposal stops accepts but does not kill returned connections. +Dispose each connection to drain Core messages, native jobs, H3 leases and handles. +Per-flow reset is intended to leave unrelated flows open; the peer-STOP case +above still blocks acceptance of that guarantee. TLS/trust/key loss closes the context. + +Native assets are separately packaged and hash-bound. Select an absolute trusted +RID asset using `NativeHttp3Library`; there is no PATH/current-directory probing. +Supported asset targets are x64 Windows and glibc Linux (minimum 2.34), not macOS, +ARM, musl or browsers. The Go image remains loaded for process lifetime. Source +checkout packaging retains the native-only HTTP/3 dependency and copies its +RID assets through NuGet. Product signing and release integration remain gated; +staged local proofs do not establish final-hash SBOM/SCA/VEX or minimum-host approval. + +The binding reserves conservative, finite additional H3/native/host capacity from +the shared application budget before H3 creation. Core application message/flow +reservations remain separate. Tune the explicit limits for the application's +concurrency rather than creating a separate budget for every connection. diff --git a/src/Opc.Ua.Bindings.WebTransport/Opc.Ua.Bindings.WebTransport.csproj b/src/Opc.Ua.Bindings.WebTransport/Opc.Ua.Bindings.WebTransport.csproj new file mode 100644 index 0000000000..1e79c4e799 --- /dev/null +++ b/src/Opc.Ua.Bindings.WebTransport/Opc.Ua.Bindings.WebTransport.csproj @@ -0,0 +1,34 @@ + + + net8.0;net9.0;net10.0 + $(CustomTestTarget) + $(LibCoreTargetFrameworks) + true + $(AssemblyPrefix).Bindings.WebTransport + $(PackagePrefix).Opc.Ua.Bindings.WebTransport + Opc.Ua.Bindings + Optional native WebTransport draft-16 binding for the common OPC UA flow runtime. + true + NugetREADME.md + true + true + true + + + $(PackageId).Debug + + + + + + + + + + + + + + diff --git a/src/Opc.Ua.Bindings.WebTransport/WebTransportDataChannelConnection.Http3.cs b/src/Opc.Ua.Bindings.WebTransport/WebTransportDataChannelConnection.Http3.cs new file mode 100644 index 0000000000..0c9a47925c --- /dev/null +++ b/src/Opc.Ua.Bindings.WebTransport/WebTransportDataChannelConnection.Http3.cs @@ -0,0 +1,476 @@ +// Copyright (c) OPC Foundation.

The runtime owns context confirmation, flow admission, revisions, +queues, lifetime and resource accounting. Identifiers in `DataChannelProfiles` +are provisional version-one profile and payload identifiers. + +There is one internal record/control implementation, under `Wire`. Generated +`Opc.Ua.DataChannel*` types are the public model; applications must not introduce +another serializer or replace opaque/PubSub payload bytes with custom framing. +The OPC 10000-28 wire revision uses binary CONTROL opcodes and FLO/ChannelId +envelopes for both UASC profiles.

Dependency injection registration +is available through `services.AddOpcUa().AddDataChannels(...)`; register the +authorizer explicitly. `IDataChannelContextFactory.Create` returns an unstarted +context so a provider can register it before transport attachment. `WaitForReadyAsync` +only waits; it never starts a handshake. + +`OpenAsync` returns after the opener's READY write, and `AcceptAsync` exposes a +remotely opened flow only after READY receipt. `AcceptAsync` may be called before +`StartAsync`. Transport, opener and Publisher roles are independent. A flow's +`Context` property is borrowed identity/routing access, not ownership of other +flows or of the underlying connection. + +## Message ownership and closure + +- Each DATA payload is a complete immutable message. `SendAsync` copies it into + bounded owned storage before awaiting transmission. +- Public `SendAsync` retains its immediate `WouldBlock` admission result. Internal + complete-chunk transports can use `SendWithAdmissionAsync` to retain the same + borrowed chunk while authorization or queue capacity is temporarily unavailable. + The caller retains its buffer until completion. Waiting uses context/application + capacity signals, not polling; no DATA identifier or message reservation is + consumed before admission, and an already admitted send is never resubmitted. +- A received `DataChannelMessage` retains both byte and message-count capacity + until disposed. Reading alone does not release credit. A reset does not reclaim + messages already handed to application code. +- Queue expiry is opt-in and local. After the carrier's `DataChannelWrite.TryCommit` + cut-off, cancellation can abandon the caller's wait but cannot free writer-owned + storage or retract numbered UASC chunks. +- `EndAsync` drains and ends the local data direction. The reverse direction and + required control can remain active. `ResetAsync` discards unsecured queues and + terminates the selected flow. + A committed revision still awaiting acknowledgement makes `EndAsync` return + `WouldBlock`; retrying the same facade is idempotent and must retain the caller's + overall deadline. +- Reset/disposal joins actual per-flow native release and outstanding writer + ownership. Repeated disposal joins the same release; a flow owner must not + destroy a shared host while that join is pending. Cleanup failures are observable. + An explicit native reset starts native stream interruption before waiting for + the common RESET record, which can itself be blocked by connection byte credit. +- Native flow/reset failures remain flow-scoped. Native management failure, + invalid authentication, and failed committed UASC chunks invalidate the context. + A datagram rejected after a path-capacity reduction is not reported as delivered. + +## Revisions and admission + +Only the opener updates a flow. Pass a complete generated descriptor to +`UpdateAsync`; immutable fields must remain equal. Explicit operation IDs enable +idempotent retries. Updates use per-direction ordered barriers and retain bounded +outcomes. A committed operation is not rolled back by timeout or ABORT. + +Old application-held messages keep their reservation after a revision changes. +Both newly admitted directions remain reserved between the first and second +directional barriers; activating one direction cannot free the other. +Datagram reception retains the prior revision for the configured monotonic grace, +bounded by the sender's old-message barrier. A third live revision is refused +until the previous network state retires. + +Shared UASC DATA credit starts at zero and includes the record and ChannelId. +Aggregate connection grants use flow/revision zero independently of per-flow +grants, so an opposite-direction revision barrier cannot strand connection credit. +Native ordered paths use actual backpressure. Physical UASC ingress transfers +its owned DATA buffer and reservation into the application queue. Capacity waits +are bounded by `DrainTimeout` from ingress admission; expiration resets the flow +rather than indefinitely stalling later controls. Datagrams use admitted +rate, burst, capacity and replay policies; they are never emulated over a reliable +stream. The application budget also offers atomic carrier reservations for +additional native/host buffers and jobs: +`DataChannelApplicationBudget.DataChannelCarrierReservation`. +Do not count logical flow/management streams twice. + +Each context reserves 512 bytes and four message slots of management headroom +against the application limits. Unused headroom is withheld from DATA and +carrier admission but is not reported as retained message storage. Control +ownership includes encoded/decoded overlap; a COMMIT also reserves its later +barrier re-encoding. Both native parser headers are admitted before allocation, +and their storage is released on stream failure or closure. + +## Authorization + +Configured policy does not require a Session or model nodes. Session providers +may use `DataChannelGrantStore` for bounded, single-use context/key/challenge-bound +grants and must independently enforce live Session permission and staged updates. +Loss of a control connection alone is not Session revocation. + +`DataChannelAuthorization.Lifetime` limits the freshness of authorization +evidence. At its deadline admission pauses while a live recheck renews or denies +permission. `RevocationToken` is an authoritative immediate revocation signal, +including during establishment. Grant redemption expiry remains a separate hard +deadline. All protocol deadlines use the injected `TimeProvider`. + +## Carrier integration + +Reliable ingress calls must preserve stream order and retain input storage until +the asynchronous receive returns. Native OPEN is itself the first common record +on a new bidirectional flow stream; bounded provisional decoding validates that +its claimed stream matches actual ingress before ACCEPT. READY and revision +barriers use the bound flow stream. There is no extra QUIC association prefix or +dummy DATA/FIN announcement. + +Adapters deliver actual native RESET/STOP signals through +`ReceiveStreamResetAsync`; this out-of-band path releases blocked ingress without +fabricating stream data or EOF. Scoped management refusals do not discard later +records in the same segment. A non-Good per-flow receive outcome is not permission +to invalidate an otherwise ready context. + +UASC adapters use the existing security sequence and single writer. Service and +control precedence applies only before DATA is secured; already numbered chunks +retain their order. SecurityMode.None is rejected. Integrity-only UASC additionally +requires explicit application and resource-policy approval. +Shared Service requests remain unsealed until arbitration; a pending control +is selected after at most eight consecutive Services, even within a coalesced +send. This is a selection bound, not a wall-clock latency guarantee. + +Reverse shared-UASC with divergent transport/UASC initiator roles is intentionally +fail-closed pending clarification of the pinned context-selector/first-HELLO rules. +Ordinary reverse Services are unaffected. This unresolved applicability is not +claimed as reverse-flow conformance. diff --git a/src/Opc.Ua.Core/Stack/DataChannels/Scheduling/DataChannelSendQueue.cs b/src/Opc.Ua.Core/Stack/DataChannels/Scheduling/DataChannelSendQueue.cs deleted file mode 100644 index 95a4519842..0000000000 --- a/src/Opc.Ua.Core/Stack/DataChannels/Scheduling/DataChannelSendQueue.cs +++ /dev/null @@ -1,393 +0,0 @@ -/* ======================================================================== - * Copyright (c) 2005-2025 The OPC Foundation, Inc.

Counts cannot decrease or +exceed the lease. Datagram acceptance is zero or full length. Progress retains the +whole lease quota. Identical terminal replays are idempotent within bounded receipt +history; stale, conflicting, unleased and unknown tokens fail without releasing credit. + +Cancellation removes only unleased body/FIN writes, preserves the association prefix, +and never frees caller-leased buffers. Once the prefix is transport-confirmed, reset +can be polled while a body write is still in flight. A failed prefix aborts the +connection; there is no unreliable-reset downgrade. + +After reset, first complete every outstanding body lease. Then submit command 22 from +the transport's **locally sent** reset observation. Never use a received peer reset, +the last write's count, queued length, or merely accepted cumulative bytes as final size. +Final size may be smaller than buffered accepted bytes; it must remain within the +cumulative accepted/admitted range and at least the reliable prefix. Only the admitted +size minus actual final size returns reserved payload credit. Header bytes are excluded. +Repeated identical confirmations are harmless; conflicting or premature confirmations +cannot create credit. + +## Resource limits and teardown + +The exact accepted overlay retains 64KiB request/capsule storage per stream/session and +128KiB aggregate bounds. This adapter permits only session zero and may impose stricter +caller-selected ingress budgets. Limits are checked **before copies**. QPACK dynamic +tables and blocked streams are disabled. Header count/bytes, input calls, uni-control +lifetime bytes, early session bytes, output bytes/events, sends, receipts and lifetime +stream/tombstone records are finite. + +Request/control input admission conservatively reserves possible decoded event counts. +Configuration rejects an event budget smaller than `header_bytes / 32 + 8`; otherwise +even a one-byte fragmented header could never be admitted. +If one input cannot fit, split the transport read into smaller ordered chunks without +altering bytes or FIN position; if current output is full, drain/complete and retry. +Do not use an input rejection as permission to drop stream bytes. Production transports +must also enforce process/connection/stream idle and lifetime policies. + +Up to 1MiB queued plus leased payload and 512 pending sends are permitted by the reviewed +maximum policy. Zero-byte writes still consume descriptors. At most 256 completion +receipts and 4096 lifetime stream records are retained. Stream IDs are never evicted and +reused; reaching the lifetime quota requires a fresh authenticated connection. +Session closure uses retained stream records as a bounded reset/STOP work list, so a +large session does not require an unbounded output batch. Unleased datagrams are dropped; +leased datagrams still require release acknowledgements. + +The host must stop new I/O, cancel transport operations, drain/acknowledge leases and +observe actual local reset completions before normal handle destruction. Dropping a +handle releases state but does not cancel real transport operations.

It is not a web server, QUIC implementation, TLS implementation, or +authentication provider. Core, ordinary Client/Server, and base PubSub do not depend +on it. No Go runtime is embedded or linked here. + +The managed WebTransport binding must separately use the one native QUIC runtime, +the stack's certificate manager, actual peer application verification, and asynchronous +transport pumps.

Static MSVC CRT. | +| `linux-x64` | glibc **2.34 or later**, `libgcc_s.so.1` with GCC ABI 3.0/3.3/4.2.0. No bundled system libraries. | + +These are the only accepted RIDs. There is no claim for musl, ARM, macOS, browsers, +older WebTransport drafts, or execution on the minimum OS version. The lower glibc +symbol requirement is not a minimum-host execution test. + +## Integration + +Use `include/opcua_http3.h` and `docs/ABI.md`. Check ABI/layouts before creation. +Pass an explicit immutable authority/resource/Origin/application-protocol policy, +resource limits, actual authenticated transport facts and externally allocated stream IDs. +One application pair and one CONNECT lifetime are pinned to each TLS connection; +cross-origin/application pooling and 0-RTT CONNECT are forbidden. + +All calls are serialized, nonblocking and callback-free. Buffers belong to the caller. +Polling a write leases a token: command 20 must acknowledge actual cumulative accepted +bytes and release. Cancellation credit is reconciled only by command 22 using the +backend's actual **local** reset final/reliable sizes. Keep leased memory alive until +the transport releases it, including during cancellation and connection teardown. + +## Source and servicing + +The package includes selected pinned HTTP3 source, the exact eight-file receive overlay, +production adapter source, public toolchain pins, build recipes, per-RID hashes/SBOMs, +and complete selected-runtime notices. See `THIRD-PARTY-NOTICES.txt`; the aggregate +package is **not MIT-only**. + +The selected upstream is `shiguredo/http3-rs` commit +`99a8c71d396b718a922f5108abe9c453c2671905`, Apache-2.0, version +`2026.1.0-canary.12`.

Both contain the same qualified native images and no managed library. +The packaging project's `netstandard2.0` target is compatibility metadata, not +a claim of a managed HTTP/3 implementation or additional platform support. +Its ordinary build needs no native compiler; packaging still requires both +verified native assets and their current receipts. + +`native-src` permits library-only reproduction (`cargo build --offline --locked --release --lib`). +Full tests and managed NativeAOT probes live in the repository's +`tests\Opc.Ua.Native.Http3.Tests`; test binaries and test identities are not shipped. + +**Release gate:** local validation packages are unsigned prereleases.

Notwithstanding that, Target Code does not include data in any +format that is used as a compiler intermediate representation, or used +for producing a compiler intermediate representation. + +The "Compilation Process" transforms code entirely represented in +non-intermediate languages designed for human-written code, and/or in +Java Virtual Machine byte code, into Target Code. Thus, for example, +use of source code generators and preprocessors need not be considered +part of the Compilation Process, since the Compilation Process can be +understood as starting with the output of the generators or +preprocessors. + +A Compilation Process is "Eligible" if it is done using GCC, alone or +with other GPL-compatible software, or if it is done without using any +work based on GCC.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. But first, please read +. diff --git a/src/Opc.Ua.Native.Http3/notices/linux/LGPL-2.1.txt b/src/Opc.Ua.Native.Http3/notices/linux/LGPL-2.1.txt new file mode 100644 index 0000000000..4362b49151 --- /dev/null +++ b/src/Opc.Ua.Native.Http3/notices/linux/LGPL-2.1.txt @@ -0,0 +1,502 @@ + GNU LESSER GENERAL PUBLIC LICENSE + Version 2.1, February 1999 + + Copyright (C) 1991, 1999 Free Software Foundation, Inc. + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + +[This is the first released version of the Lesser GPL. It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It applies to a given file (the "Runtime Library") that +bears a notice placed by the copyright holder of the file stating that +the file is governed by GPLv3 along with this Exception. + +When you use GCC to compile a program, GCC may combine portions of +certain GCC header files and runtime libraries with the compiled +program. The purpose of this Exception is to allow compilation of +non-GPL (including proprietary) programs to use, in this way, the +header files and runtime libraries covered by this Exception. + +0. Definitions. + +A file is an "Independent Module" if it either requires the Runtime +Library for execution after a Compilation Process, or makes use of an +interface provided by the Runtime Library, but is not otherwise based +on the Runtime Library. + +"GCC" means a version of the GNU Compiler Collection, with or without +modifications, governed by version 3 (or a specified later version) of +the GNU General Public License (GPL) with the option of using any +subsequent versions published by the FSF. + +"GPL-compatible Software" is software whose conditions of propagation, +modification and use would permit combination with GCC in accord with +the license of GCC. + +"Target Code" refers to output from any compiler for a real or virtual +target processor architecture, in executable form or suitable for +input to an assembler, loader, linker and/or execution +phase. Notwithstanding that, Target Code does not include data in any +format that is used as a compiler intermediate representation, or used +for producing a compiler intermediate representation. + +The "Compilation Process" transforms code entirely represented in +non-intermediate languages designed for human-written code, and/or in +Java Virtual Machine byte code, into Target Code. Thus, for example, +use of source code generators and preprocessors need not be considered +part of the Compilation Process, since the Compilation Process can be +understood as starting with the output of the generators or +preprocessors. + +A Compilation Process is "Eligible" if it is done using GCC, alone or +with other GPL-compatible software, or if it is done without using any +work based on GCC. For example, using non-GPL-compatible Software to +optimize any GCC intermediate representations would not qualify as an +Eligible Compilation Process. + +1. Grant of Additional Permission. + +You have permission to propagate a work of Target Code formed by +combining the Runtime Library with Independent Modules, even if such +propagation would otherwise violate the terms of GPLv3, provided that +all Target Code was generated by Eligible Compilation Processes. You +may then convey such a combination under terms of your choice, +consistent with the licensing of the Independent Modules. + +2. No Weakening of GCC Copyleft. + +The availability of this Exception does not imply any general +presumption that third-party software is unaffected by the copyleft +requirements of the license of GCC. + + +libquadmath/*.[hc]: + + Copyright (C) 2010 Free Software Foundation, Inc. + Written by Francois-Xavier Coudert + Written by Tobias Burnus + +This file is part of the libiberty library. +Libiberty is free software; you can redistribute it and/or +modify it under the terms of the GNU Library General Public +License as published by the Free Software Foundation; either +version 2 of the License, or (at your option) any later version. + +Libiberty is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

2026, AND TRIAL EDITION +Last Updated: October 1, 2025. +These license terms are an agreement between you and Microsoft Corporation (or based on where you live, one of its affiliates). They apply to the software named above. The terms also apply to any Microsoft services and updates for the software, except to the extent those have different terms. +Unless otherwise stated, these license terms remain in effect for this version of Visual Studio and any updates or revisions released. Microsoft may update or modify these license terms at any time. It is your responsibility to regularly review the license terms and any related announcements. The most current version of the license terms will always be available at https://aka.ms/VisualStudioLicenses. By continuing to use the software after changes are posted, you agree to the updated terms. +BY USING THE SOFTWARE, YOU ACCEPT THESE TERMS. IF YOU DO NOT ACCEPT THEM, DO NOT USE THE SOFTWARE. INSTEAD, RETURN IT TO THE RETAILER FOR A REFUND OR CREDIT. If you cannot obtain a refund there, contact Microsoft about Microsoft’s refund policies. See www.microsoft.com/worldwide. In the United States and Canada, call (800) MICROSOFT or see aka.ms/nareturns. + +TRIAL EDITION TERMS OF USE. If you have not acquired a valid full-use license, the software is a trial edition, and this Section I applies to your use of the trial edition. In addition to the terms of this Section I, the terms of Sections II.4–5, II.6(d) – (g), II.8–10, II.15, and II.17–18 apply to the trial edition, and Section II.3 applies to Previews (as defined in in Section II.3 below) made available to you as part the trial edition. +TRIAL EDITIONS. You may use any number of copies of the trial edition or Insiders Channel Software on your devices for internal evaluation purposes during the trial period (as described herein). You may not distribute or deploy into production any applications you make with the trial edition to a production environment. You may run load tests of up to 250 virtual users during the trial period. +TRIAL PERIOD AND CONVERSION. The trial period for the trial edition lasts for 30 days after you first install a trial edition, plus any permitted extension period. After the expiration of the trial period, the trial edition will stop running. You may extend the trial period an additional 90 days if you sign in to the software. You may not be able to access data used with the trial edition after it stops running. You may convert your trial rights at any time to the full-use rights described in Section II below by acquiring a valid full-use license. +Disclaimer of Warranty. The TRIAL EDITION IS licensed “as-is”. You bear the risk of using IT. Microsoft gives no express warranties, guarantees or conditions. To the extent permitted under your local laws, Microsoft excludes the implied warranties of merchantability, fitness for a particular purpose and non-infringement. +FOR AUSTRALIA – You have statutory guarantees under the Australian Consumer Law and nothing in these terms is intended to affect those rights. +SUPPORT. Because the trial edition is “as is”, we may not provide support services for it. +Limitations on Damages. You can recover from Microsoft and its suppliers only direct damages up to U.S. $5.00. You cannot recover any other damages, including consequential, lost profits, special, indirect or incidental damages. +This limitation applies to (a) anything related to the trial version, services, content (including code) on third party Internet sites, or third party applications; and (b) claims for breach of contract, breach of warranty, guarantee or condition, strict liability, negligence, or other tort to the extent permitted by applicable law. +It also applies even if Microsoft knew or should have known about the possibility of the damages. The above limitation or exclusion may not apply to you because your country may not allow the exclusion or limitation of incidental, consequential or other damages. + + +FULL-USE LICENSE TERMS OF USE FOR THE SOFTWARE: When you acquire a valid license and either enter a product key or sign in to the software, the terms in this Section II apply instead of the terms in Section I. You may not share your product key or access credentials. +OVERVIEW +Software. The software includes developmental tools, applications, and documentation. +License Model. The software is licensed on a per user basis. +INSTALLATION AND USE RIGHTS. +General. One user (referred to as “you” or “your”) may install and use copies of the software on your devices to develop and test applications. This includes using copies of the software on your own internal servers that remain fully dedicated to your own use. You may not, however, separate the components of the software (except as otherwise stated in these license terms) and run those in a production environment, or on third party devices, or for any purpose other than developing and testing your applications. Running the software on Microsoft Azure may require separate usage fees. +Workloads. These license terms apply to your use of the workloads made available to you within the software, except to the extent a workload or a workload component comes with different license terms and support policies. +Backup Copy. You may make one backup copy of the software, for reinstalling the software. +Demo Use. The uses permitted above include use of the software to demonstrate your applications. +INSIDERS, PREVIEWS, AND PRE-RELEASE SOFTWARE. Microsoft may make the software available to you through the Insiders Channel (“Insiders Channel Software”) or may make available to you pre-release or preview features or components (“Preview Features”) through the Stable Channel. Insiders Channel software and Preview Features (collectively, “Previews”), the Insiders Channel, and Stable Channel are further described at https://aka.ms/vs/18/channels-overview. +You may use any number of copies of Insiders Channel Software only for internal evaluation purposes. +Preview Features may be used consistent with your use rights to the software. +Previews are experimental and may be substantially different from the commercially released version. They may not operate correctly or work the way a final version will. Microsoft may change Previews for the final, commercial version, if any. +Microsoft is not obligated to provide maintenance, technical support or updates to you for Previews. +Any separate components, such as frameworks, runtimes, or compilers, that are marked as “Insiders”, “preview”, “pre-release”, or “beta” (collectively, “Unreleased Components”) included with Previews are solely for internal evaluation purposes. You may not distribute or deploy into production software that depends on them. Unreleased Components may be subject to separate terms. +FEEDBACK. If you give feedback, suggestions, or recommendations (collectively, “Feedback”) about the software to Microsoft, you give to Microsoft, without charge, the right to use, share, and commercialize your Feedback in any way and for any purpose. You will not give Feedback that is a third party’s confidential information or subject to a license that requires Microsoft to license its software or documentation to third parties because we include your Feedback in them. These rights survive this agreement. +ONLINE SERVICES IN THE SOFTWARE. Some features of the software make use of online services to provide you information about updates to the software or extensions, or to enable you to retrieve content, collaborate with others, or otherwise supplement your development experience. As used throughout these license terms, the term “software” includes these online service features, and by using them, you consent to the transmission of information as described in Section 9, DATA. +GitHub Copilot. The software enables you to interact with the GitHub Copilot service (“Copilot”) offered by GitHub, Inc. (“GitHub”). You must separately obtain access to Copilot to use this functionality, and your use of Copilot is pursuant to the separate agreement(s) between you and GitHub, including any of its data collection provisions +TERMS FOR SPECIFIC COMPONENTS. +Separation of Components; Workloads. Except as otherwise stated in these license terms, (i) the components of the software are licensed as a single unit, and (ii) you may not separate the components and install them on different devices. These license terms apply to your use of the workloads made available within the software, except to the extent that a workload or a workload component comes with different terms. +Utilities. The software contains items on the Utilities List at https://aka.ms/vs/18/utilities (“Utilities”). You may copy and install those items onto your devices to debug and deploy your applications and databases you develop with the software. The Utilities are designed for temporary use. Microsoft may not be able to patch or update Utilities separately from the rest of the software. Some Utilities by their nature may make it possible for others to access the devices on which the Utilities are installed. You should delete all Utilities you have installed after you finish debugging or deploying your applications and databases. Microsoft is not responsible for any third party use or access of devices, or of the applications or databases on devices, on which Utilities have been installed. +Build Devices and Visual Studio Build Tools. You may copy and install files from the software or from Visual Studio Build Tools onto your build devices, including physical devices and virtual machines or containers on those devices, whether on-premises or remote machines that are (i) owned by you, (ii) hosted on Microsoft Azure for you, or (iii) under the day-to-day management and control of an Authorized Outsourcer (as defined below) and dedicated solely to your use (collectively, “Build Devices”). You and others in your organization may use these files on your Build Devices solely to compile, build, and verify applications developed by using the software, or run quality or performance tests of those applications as part of the build process. +“Authorized Outsourcer” means any third party service provider that is not a Listed Provider and is not using Listed Provider as a Data Center Provider as part of the outsourcing service. +“Listed Providers” include entities identified by Microsoft at http://aka.ms/listedproviders. Microsoft may identify additional Listed Providers at http://aka.ms/listedproviders from time to time; however, if you are using an outsourcer at the time its Authorized Outsourcer status is terminated, then you may temporarily continue to use the same entity in its former Authorized Outsourcer capacity for one year from the date of that change in status. +“Data Center Provider” means an entity that provides infrastructure or software services, directly or indirectly, to another service provider. Microsoft may also serve as a Data Center Provider through Microsoft Azure. +Code Inspection. This software includes functionality that enables you to inspect binary code and reproduce source code from original binary code. Use of these features of the software is entirely optional. By using this functionality, you acknowledge that the binary code and source code may be protected by copyright and trademark laws. You also agree not to violate any applicable copyright and trademark laws or license agreements, and represent that you will have obtained permission or otherwise be permitted to inspect binary code and reproduce source code if you use this functionality. Microsoft is not responsible for any uses by you in violation of applicable laws or license agreements. +Fonts. While the software is running, you may use its fonts to display and print content. You may only: (i) embed fonts in content as permitted by the embedding restrictions in the fonts; and (ii) temporarily download them to a printer or other output device to print content. +IntelliSense Service. This service provides a base model trained on publicly available open source code that enables you to receive AI-assisted IntelliSense suggestions. You may only use the base model, in whole or in part, with the software. AI-assisted IntelliSense analyzes your application locally to generate a summary file with metadata on the types and their usage across your application which illustrate your patterns of usage. The summary file contains information about the names of classes, methods, and how often they are used in your application (“Your Data”). You retain ownership of all aspects of Your Data, including, but not limited to, all right, title and interest in and to the underlying application code. +Licenses for Other Components. +Microsoft Platforms. The software may include components from Microsoft Windows, Microsoft Windows Server, Microsoft SQL Server, Microsoft Exchange, Microsoft Office, Microsoft SharePoint, Microsoft Visual C++, or other Microsoft software. These components are governed by separate agreements and their own product support policies, as described in the Microsoft “Licenses” folder accompanying the software, or at https://aka.ms/vs/18/AdditionalLicenses, except that, if separate license terms for those components are included in the associated installation directly, those license terms control. +Third Party or Open Source Components. The software may include third party or open source components with separate legal notices or governed by other agreements, as may be described in the notices file(s) accompanying the software. +Package Managers. The software includes package managers, like NuGet and vcpkg, that give you the option to download other Microsoft and third party software packages to use with your applications. Those packages are under their own licenses, and not these license terms. Microsoft does not distribute, license or provide any warranties for any of the third party packages. +DISTRIBUTABLE CODE. The software contains code that you may distribute in applications you develop as described in this Section. For purposes of this Section, the term “distribution” also means deployment of your applications for third parties to access over the Internet. +Right to Use and Distribute. The code and text files listed in (i) and (ii) below are “Distributable Code”. +Distributable List. You may copy and distribute the object code form of code listed on the Distributable List located at https://aka.ms/vs/18/redistribution. +Sample Code, Templates, and Styles. You may copy, modify, and distribute the source and object code form of code marked as “sample”, “template”, “simple styles”, and “sketch styles”. +Third Party Distribution. You may permit distributors of your applications to copy and distribute the Distributable Code as part of those applications. +Distribution Requirements. For any Distributable Code you distribute, you must: +add significant primary functionality to it in your applications; +require distributors and external end users to agree to terms that protect the Distributable Code at least as much as these license terms; and +indemnify, defend, and hold harmless Microsoft from any claims, including attorneys’ fees, related to the distribution or use of your applications, except to the extent that any claim is based solely on the Distributable Code. +Distribution Restrictions. You may not: +distribute Unreleased Components; +distribute software developed with Insiders Channel Software or that depends on Unreleased Components; +use Microsoft’s trademarks in your applications’ names or in a way that suggests your applications come from or are endorsed by Microsoft; or +modify or distribute the source code of any Distributable Code so that any part of it becomes subject to an Excluded License. An Excluded License is one that requires, as a condition of use, modification or distribution of code, that (i) it be disclosed or distributed in source code form; or (ii) others have the right to modify it. +DEVELOPING EXTENSIONS. +Limits on Extensions. You may not develop or enable others to develop extensions for the software (or any other component of the Visual Studio family of products) which circumvent the technical limitations implemented in the software. If Microsoft technically limits or disables extensibility for the software, you may not extend the software by, among other things, loading or injecting into the software any non-Microsoft add-ins, macros, or packages; modifying the software registry settings; or adding features or functionality equivalent to that found in the Visual Studio family of products. +No Degrading the Software. If you develop an extension for the software (or any other component of the Visual Studio family of products), you must test the installation, uninstallation, and operation of your extension to ensure that such processes do not disable any features or adversely affect the functionality of the software (or such component) or of any previous version or edition of thereof. +DATA. +Data Collection. The software may collect information about you and your use of the software, and send that information to Microsoft (“Usage Data”). Microsoft may use this information to provide services and improve our products and services. You may opt out of many of these scenarios, but not all, as described in the software documentation. There are also some features in the software that may enable you and Microsoft to collect data from users of your applications. If you use these features, you must comply with applicable law, including providing appropriate notices to users of your applications together with a copy of Microsoft’s privacy statement. Our privacy statement is located at http://aka.ms/privacy. You can learn more about data collection and its use from the software documentation and our privacy statement. Your use of the software operates as your consent to these practices. +Processing of Personal Data. To the extent Microsoft is a processor or subprocessor of personal data in connection with the software, Microsoft makes the commitments in the European Union General Data Protection Regulation Terms of the Microsoft Products and Services Data Protection Addendum to all customers effective May 25, 2018, at https://docs.microsoft.com/legal/gdpr. +Data Sharing with GitHub: If you give Feedback about the software to Microsoft, and Microsoft determines that your feedback directly relates to Copilot, Microsoft may, without charge, share the Feedback and Usage Data with GitHub, and you give to GitHub (i) the right to use, share, and commercialize your Feedback in any way and for any purpose, and (ii) the right to use Usage Data for the purpose of improving GitHub offerings. +SCOPE OF LICENSE. The software is licensed, not sold. These license terms only give you some rights to use the software. Microsoft reserves all other rights. Unless applicable law gives you more rights despite this limitation, you may use the software only as expressly permitted in these license terms. In doing so, you must comply with any technical limitations in the software that only allow you to use it in certain ways. In addition, you may not: +work around any technical limitations in the software; +reverse engineer, decompile, or disassemble the software, or otherwise attempt to derive the source code for the software, except and to the extent required by third party licensing terms governing use of certain open-source components that may be included with the software; +remove, minimize, block, or modify any notices of Microsoft or its suppliers in the software; +use the software in any way that is against the law; +share, publish, rent, or lease the software; or +provide the software as a stand-alone offering or combine it with any of your applications for others to use. +NOT FOR RESALE SOFTWARE. You may not sell the software if it is marked as “NFR” or “Not for Resale”. +PREVIOUS VERSIONS OR OTHER EDITIONS. These license terms do not supersede your right to use validly licensed previous versions or other editions of the software subject to the applicable license terms. You may use the software and those previous versions or other editions of the software concurrently. +PROOF OF LICENSE. If you purchased an online copy of the software, your proof of license is the Microsoft product key you received with your purchase and your receipt and/or being able to access the software service through your Microsoft account. To identify genuine Microsoft software, see www.howtotell.com. +TRANSFER TO A THIRD PARTY. If you are a valid licensee of the software, you may transfer it and this agreement directly to another party. Before the transfer, that party must agree that these license terms apply to the transfer and use of the software. The transfer must include the software, this agreement, the genuine Microsoft product key, and (if applicable) the Proof of License label. The transferor must uninstall all copies of the software after transferring it from the device. The transferor may not retain any copies of the genuine Microsoft product key to be transferred, and may only retain copies of the software if otherwise licensed to do so. If you have acquired a non-perpetual license to use the software, Visual Studio Subscriptions software, or if the software is marked Not for Resale you may not transfer the software or the software license agreement to another party. +COMPLIANCE WITH TRADE LAWS. Microsoft products, software, technology, and services (“Items”) may be subject to U.S. and other countries’ export jurisdictions. Each party will comply with all laws and regulations applicable to the import or export of the Items, including, without limitation, trade laws of the U.S., EU, and UK, such as the U.S. Export Administration Regulations, sanctions regulations administered by the U.S. Office of Foreign Assets Control, the EU Dual Use Regulation 2021/821, and/or other end-user, end use, and destination restrictions (“Trade Laws”) as well as the global legal compliance standards detailed in the Microsoft Standards of Business Conduct. You will not, and will ensure your Affiliates will not, take any action that causes Microsoft to violate applicable Trade Laws. Microsoft may suspend or terminate this agreement immediately without notice to the extent that Microsoft reasonably believes that performance would cause it to violate Trade Laws or put it at risk of becoming subject to sanctions and penalties under such laws. You remain responsible for its and for your Affiliates’ compliance with this section. For additional information, see www.microsoft.com/exporting. +You must ensure that you, any of your directors or officers, or to the best of your knowledge, your employees or agents, Affiliates, or Affiliates’ directors, officers, employees, or agents are not sanctioned persons designated under applicable Trade Laws. +You shall provide Microsoft with prompt written notice if you or any of your Affiliates receive notice from any government agency of any investigation, inquiry, or proceeding for any actual or alleged noncompliance of or with any Trade Laws related to activities subject to this Agreement. +You shall comply with global use restrictions in Microsoft’s product or service terms relevant to this agreement, as updated from time to time. +You shall not make available Microsoft Items to any entity or individual designated on any export or sanctions restriction lists under Trade Laws, in each case, without specific government authorization required by Trade Laws. +For the purposes of this Section 15, “Affiliate” means any legal entity that directly or indirectly owns, is owned by, or is commonly owned with the applicable party. “Own” means having more than 50% ownership or the right to direct the management of the entity. +SUPPORT. Microsoft provides support for the software as described at https://support.microsoft.com. +ENTIRE AGREEMENT. These license terms (including the warranty below), and the terms for supplements, updates, Internet-based services, and support services, are the entire agreement for the software and support services. +APPLICABLE LAW. If you acquired the software in the United States, Washington state law applies to interpretation of, and claims for breach of these license terms, and the laws of the state where you live apply to all other claims. If you acquired the software in any other country, its laws apply. +CONSUMER RIGHTS; REGIONAL VARIATIONS. These license terms describe certain legal rights. You may have other rights, including consumer rights, under the laws of your state or country. Separate and apart from your relationship with Microsoft, you may also have rights with respect to the party from which you acquired the software. These license terms do not change those other rights if the laws of your state or country do not permit it to do so. For example, if you acquired the software in one of the below regions, or if mandatory country law applies, then the following provisions apply to you: +Australia. References to “Limited Warranty” are references to the express warranty provided by Microsoft. This warranty is given in addition to other rights and remedies you may have under law, including your rights and remedies in accordance with the statutory guarantees in the Australian Consumer Law. +In this section, “goods” refers to the software for which Microsoft provides the express warranty. Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure. +Canada. You may stop receiving updates on your device by turning off Internet access. If and when you re-connect to the Internet, the software will resume checking for and installing updates. The product documentation, if any, may also specify how to turn off updates for your specific device or software. +Germany and Austria. +Warranty. The properly licensed software will perform substantially as described in any Microsoft materials that accompany it. However, Microsoft gives no contractual guarantee in relation to the software. +Limitation of Liability. In case of intentional conduct, gross negligence, claims based on the Product Liability Act, as well as, in the case of death or personal or physical injury, Microsoft is liable according to the statutory law. +Subject to the preceding sentence (ii), Microsoft will only be liable for slight negligence if Microsoft is in breach of such material contractual obligations, the fulfillment of which facilitate the due performance of these license terms, the breach of which would endanger the purpose of these license terms and the compliance with which a party may constantly trust in (so-called "cardinal obligations"). In other cases of slight negligence, Microsoft will not be liable for slight negligence. + +******************************************************************************************** +LIMITED WARRANTY +Microsoft warrants that properly licensed software will perform substantially as described in any Microsoft materials that accompany the software. This limited warranty does not cover problems that you cause, that arise when you fail to follow instructions, or that are caused by events beyond Microsoft’s reasonable control. The limited warranty starts when the first user acquires the software, and lasts for one year. Any supplements, updates, or replacement software that you may receive from Microsoft during that year are also covered, but only for the remainder of that one-year period or for 30 days, whichever is longer. Transferring the software will not extend the limited warranty. +Microsoft gives no other express warranties, guarantees, or conditions. Microsoft excludes all implied warranties and conditions, including those of merchantability, fitness for a particular purpose, and non-infringement. If your local law does not allow the exclusion of implied warranties, then any implied warranties, guarantees, or conditions last only during the term of the limited warranty and are limited as much as your local law allows. If your local law requires a longer limited warranty term, despite this agreement, then that longer term will apply, but you can recover only the remedies this agreement allows. +If Microsoft breaches its limited warranty, it will, at its election, either: (i) repair or replace the software at no charge, or (ii) accept return of the software (or at its election the Microsoft branded device on which the software was preinstalled) for a refund of the amount paid, if any. These are your only remedies for breach of warranty. This limited warranty gives you specific legal rights, and you may also have other rights which vary from state to state or country to country. +Except for any repair, replacement, or refund Microsoft may provide, you may not recover under this limited warranty, under any other part of this agreement, or under any theory, any damages or other remedy, including lost profits or direct, consequential, special, indirect, or incidental damages. The damage exclusions and remedy limitations in this agreement apply even if repair, replacement or a refund does not fully compensate you for any losses, if Microsoft knew or should have known about the possibility of the damages, or if the remedy fails of its essential purpose. Some states and countries do not allow the exclusion or limitation of incidental, consequential, or other damages, so those limitations or exclusions may not apply to you. If your local law allows you to recover damages from Microsoft even though this agreement does not, you cannot recover more than you paid for the software (or up to $50 USD if you acquired the software for no charge). +Warranty Procedures +For service or a refund, you must provide a copy of your proof of purchase and comply with Microsoft’s return policies, which might require you to uninstall the software and return it to Microsoft or return the software with the entire Microsoft branded device on which the software is installed; the certificate of authenticity label including the product key (if provided with your device) must remain affixed. +1.United States and Canada. For limited warranty service or information about how to obtain a refund for software acquired in the United States or Canada, contact Microsoft via telephone at (800) MICROSOFT; via mail at Microsoft Customer Service and Support, One Microsoft Way, Redmond, WA 98052-6399; or visit (aka.ms/nareturns). +2.Europe, Middle East, and Africa. If you acquired the software in Europe, the Middle East, or Africa, Microsoft Ireland Operations Limited makes the limited warranty. To make a claim under the limited warranty, you must contact either Microsoft Ireland Operations Limited, Customer Care Centre, Atrium Building Block B, Carmanhall Road, Sandyford Industrial Estate, Dublin 18, Ireland, or the Microsoft affiliate serving your country (aka.ms/msoffices). +3.Australia. If you acquired the software in Australia, contact Microsoft to make a claim at 13 20 58; or Microsoft Pty Ltd, 1 Epping Road, North Ryde NSW 2113 Australia. +4.Other countries. If you acquired the software in another country, contact the Microsoft affiliate serving your country (aka.ms/msoffices). + +EULAID: VS2026_EntPro_ENU.1033 diff --git a/src/Opc.Ua.Native.Http3/notices/microsoft/vs2026-pro-enterprise.txt b/src/Opc.Ua.Native.Http3/notices/microsoft/vs2026-pro-enterprise.txt new file mode 100644 index 0000000000..eec969726e --- /dev/null +++ b/src/Opc.Ua.Native.Http3/notices/microsoft/vs2026-pro-enterprise.txt @@ -0,0 +1,352 @@ + + + + + + + + License Terms | Microsoft Visual Studio Enterprise 2026, Visual Studio Professional 2026, and Trial Edition - Visual Studio + + + + + + + + + + + + + + + + + + + + + + + + + Skip to main content + + + + + + Visual Studio + +Overview +Features +Editions +Extensions +Get StartedFAQ Support +Documentation +Service Status +Blog + + Downloads + + Buy + + + + Overview + Support + Administrator Portal + Subscriber Portal + Dev Essentials + + + Free Visual Studio + + + + + + Microsoft Security + Azure + Dynamics 365 + Microsoft 365 + Microsoft Teams + Windows 365 + + + Microsoft AI + Azure Space + Mixed reality + Microsoft HoloLens + Microsoft Viva + Quantum computing + Sustainability + + + Education + Automotive + Financial services + Government + Healthcare + Manufacturing + Retail + + + Find a partner + Become a partner + Partner Network + Microsoft Marketplace + Software companies + + + Blog + Microsoft Advertising + Developer Center + Documentation + Events + Licensing + Microsoft Learn + Microsoft Research + + + View Sitemap + + + + + + + + + + + + + + + + + This device is not currently supported for these products. + + + + + Visual Studio IDE + + + + Visual Studio Insiders + + + + + + + + + To continue downloading, click here + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + License Terms | Microsoft Visual Studio Enterprise 2026, Visual Studio Professional 2026, and Trial Edition2025-10-31T15:31:48-07:00 + + + + + + + + + + + + + + + + + + + + + + + + + Follow us + + + + + + + + + Dev Essentials + + Developer Community + + + + + Blogs: + Visual Studio + .NET + C++ + + + + + + + + + + + + + + + + + + + + + + + + Surface Laptop Ultra + Surface Pro + Surface Laptop + Surface RTX Spark Dev Box + Explore Copilot + Explore Microsoft products + Windows 11 apps + + + Account profile + Download Center + Microsoft Store support + Returns + Order tracking + Certified Refurbished + Why buy from Microsoft Store + Flexible Payments + + + Microsoft in education + Devices for education + Microsoft Teams for Education + Microsoft 365 Education + How to buy for your school + Educator training and development + Deals for students and parents + AI for education + + + + + + Microsoft AI + Microsoft Security + Dynamics 365 + Microsoft 365 + Microsoft Power Platform + Microsoft Teams + Microsoft Copilot + Small Business + + + Azure + Microsoft Developer + Microsoft Learn + Support for AI marketplace apps + Microsoft Tech Community + Microsoft Marketplace + Software companies + Visual Studio + + + Careers + About Microsoft + Company news + Privacy at Microsoft + Investors + Diversity and inclusion + Accessibility + Sustainability + + + + English (United States) + + + + + Your Privacy Choices Opt-Out Icon + + + + + + Your Privacy Choices + + + + + Your Privacy Choices Opt-Out Icon + + + + + + Your Privacy Choices + + + + Consumer Health Privacy + + Contact us + Privacy & cookies + Manage cookies + Terms of use + Trademarks + About our ads + + + + + + + + diff --git a/src/Opc.Ua.Native.Http3/notices/microsoft/vs2026-redist.txt b/src/Opc.Ua.Native.Http3/notices/microsoft/vs2026-redist.txt new file mode 100644 index 0000000000..9248fced01 --- /dev/null +++ b/src/Opc.Ua.Native.Http3/notices/microsoft/vs2026-redist.txt @@ -0,0 +1,863 @@ + + + + + Visual Studio Redistribution | Microsoft Learn + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Skip to main content + + + + Skip to Ask Learn chat experience + + + + + + + + + This browser is no longer supported. + + + Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. + + + + Download Microsoft Edge + + + More info about Internet Explorer and Microsoft Edge + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Table of contents + + + + Exit editor mode + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Ask Learn + + + + + + Ask Learn + + + + + + + + + + + + + + + + Reading mode + + + + + Table of contents + + + + + + + Read in English + + + + + + + + Add + + + + + + + Add to Plans + + + + + + + + + + + + Copy Markdown + + + + + + + Print + + + + + + + + + + + + + + + + + + + + Note + + + Access to this page requires authorization.

+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+   copyright notice that is included in or attached to the work

+   form, that is based on (or derived from) the Work and for which the
+   editorial revisions, annotations, elaborations, or other modifications
+   represent, as a whole, an original work of authorship. For the purposes

+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,

+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+

+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and

+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+   form, that is based on (or derived from) the Work and for which the
+   editorial revisions, annotations, elaborations, or other modifications
+   represent, as a whole, an original work of authorship. For the purposes

+
+   "Contributor" shall mean Licensor and any individual or Legal Entity

+
+2. Grant of Copyright License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of

+   by such Contributor that are necessarily infringed by their

+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+

+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and

+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of

+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,

+
+7. Disclaimer of Warranty. Unless required by applicable law or

+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not

+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.

+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.

+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not

+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution

+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or

+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,

+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed

+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of

+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)

+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate

+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:

+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and

+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed

+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each

+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.
+
+END OF TERMS AND CONDITIONS

+   by such Contributor that are necessarily infringed by their

+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:

+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+   as of the date such litigation is filed.
+

+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with

+5. Submission of Contributions. Unless You explicitly state otherwise,

+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,

+   implied, including, without limitation, any warranties or conditions

+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)

+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not

+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and

+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or

+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+   including but not limited to software source code, documentation
+   source, and configuration files.
+
+   "Object" form shall mean any form resulting from mechanical
+   transformation or translation of a Source form, including but
+   not limited to compiled object code, generated documentation,
+   and conversions to other media types.
+
+   "Work" shall mean the work of authorship, whether in Source or
+   Object form, made available under the License, as indicated by a
+   copyright notice that is included in or attached to the work
+   (an example is provided in the Appendix below).
+
+   "Derivative Works" shall mean any work, whether in Source or Object
+   form, that is based on (or derived from) the Work and for which the
+   editorial revisions, annotations, elaborations, or other modifications
+   represent, as a whole, an original work of authorship. For the purposes
+   of this License, Derivative Works shall not include works that remain
+   separable from, or merely link (or bind by name) to the interfaces of,
+   the Work and Derivative Works thereof.
+
+   "Contribution" shall mean any work of authorship, including
+   the original version of the Work and any modifications or additions

+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   (except as stated in this section) patent license to make, have made,
+   use, offer to sell, sell, import, and otherwise transfer the Work,
+   where such license applies only to those patent claims licensable
+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+

+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

Releasing + a stream removes its facts; allocator high-water rejects late recreation of them. +- Persistent native state is separately bounded by the handle/handshake/window limits. + `retained_bytes` is not a claim to measure all Go/TLS/socket memory. + +One read and one write can operate concurrently on a stream. A reset cannot overtake +an active write; release cannot invalidate any referencing job, even an unreleased +terminal job. Connection close interrupts its native I/O, but connection release +requires all child streams and referencing jobs to be released. Listener close drains +unaccepted peers and releases its own socket reference; accepted connections retain +their transport independently until they close. Counters can be used to verify complete +shutdown (allowing finite background transport cleanup). + +## Security and transport evidence + +Every endpoint has a supplied leaf, intermediates, private key, trust anchors and local +URI. Every peer rule requires an exact certificate URI SAN **and** SHA256 SPKI pin. +TLS performs ordinary chain/lifetime/EKU validation, plus connector hostname validation. +Unknown roots, malformed material, missing key capability and empty policy fail closed. +The listener's rule array is explicit and extensible to multiple applications/key rotations; +there is no single hardcoded client and no authorization based on application records. +Policies are immutable snapshots. Providers must enforce any additional revocation, +trust-list or authorization rules before supplying a snapshot and close affected live +connections when such policy changes. Online revocation fetches are not implemented. + +TLS 1.3 only; no tickets, resumption or early/0RTT endpoint API. Successful connector +admission requires observation of a CertificateRequest, selection of the configured local +certificate, completed TLS Certificate/CertificateVerify/Finished processing, verified expected +peer identity, and authenticated HANDSHAKE_DONE receipt. A pinned/trusted server that omits +CertificateRequest is refused, not treated as mutually authenticated. Server admission requires +its own per-connection certificate selection and native post-client-auth handshake completion. +Higher-layer application acceptance/authorization remains separate. + +The ABI2 layout, retained by ABI3 and ABI4, appends independent observations to the first 904 info bytes: +`handshake_confirmed` at904, `mutual_tls_authenticated` at908, `local_certificate_used` at912, +and zero `reserved` at916. Offset16 remains **local TLS HandshakeComplete**, not QUIC +confirmation. Managed loading requires ABI4/info920. ABI1 lacks the authentication facts, +ABI2 lacks the independent received-reset watcher, and ABI3 lacks the actual peer-STOP +watcher; none is silently assumed. The ten export signatures and structure sizes are +unchanged by these additive operation revisions. + +Peer facts return the actual verified certificate chain, authorized URI, leaf/SPKI hashes, +ALPN and TLS/transport facts. Exact **remote** TP `0x1d` comes from the observation overlay, +not the native merged draft07/09 capability. Local emission is the source-pinned native +encoder, golden-tested for empty TP `0x1d`. No wire encoder/decoder behavior is patched. +Typed `HandshakeConfirmed`, `MutualTlsAuthenticated` and `LocalCertificateUsed` properties +reflect those new native fields. Typed reset09 flags map to empty TP `0x1d` and frame `0x24`; +that protocol mapping is not an observation that a reset has already been transmitted. + +## Stream completion and reliable reset + +Native allocation supplies real bidirectional/unidirectional IDs. For H3, the host reserves +client bidi0 for CONNECT and three actual uni IDs for control/QPACK before allocating +application streams. This backend does not reserve or interpret H3/flow records. + +Write completion reports **actual accepted bytes**, including partial errors. FIN is +reported successful only after the native send Close succeeds. Boundary flag2 writes +the entire supplied prefix, then calls native `SetReliableBoundary` before returning. +Immediate cancellation cannot overtake this marking. A failed partial prefix closes +that connection rather than emitting an unassociated reset. Reset/close outcomes never +derive final size from leased payloads. + +`WaitResetSent` waits for the actual **local** native packetizer frame and returns final +size, reliable size, application error and original native encoder codepoint `0x24` +or `0x04`. An ordinary reset can follow an actual peer STOP_SENDING even after a reliable +boundary was established; see the policy limitation below. Reads return data before FIN/reset outcome. +Received reset metadata is independently observed; it is not substituted for local +send confirmation. `SentOffset` reports transmitted STREAM high-water, not Write counts. + +`WaitResetReceived` (stream operation28, operation revision2) independently waits for actual +peer RESET_STREAM/RESET_STREAM_AT metadata already captured by the native packet recorder. +It can run while Read is paused by application backpressure, or concurrently with Read/Write. +It returns `Remote=true`, reset outcome, actual error/final/reliable/frame values and no payload. +It neither consumes bytes nor cancels either direction; reliable prefix bytes may still be +buffered and must retain their normal ownership/processing rules. It is distinct from +`WaitPeerStopped`, which observes a peer STOP_SENDING directed at the local send half. +Cancelling/timing out this watcher produces no invented EOF/reset evidence. + +Operation28 was introduced with ABI3/revision2. Keep the watcher bounded and drain/release +it before releasing its stream. + +### Actual peer STOP and crossed resets + +`WaitPeerStopped` (stream operation29, operation revision3) observes the first authenticated +received STOP_SENDING frame for a send-capable stream. Success returns `Remote=true`, the +actual stream ID and peer application error, including error zero. Payload, byte count, +final size, reliable size and reset frame type remain zero: a STOP is not a reset. +It is independent of Read, Write and local send cancellation. A local Reset or FIN cannot +complete it as peer evidence. Cancellation, timeout or connection closure without a +recorded STOP fails without inventing a peer error. Repeated completed observations retain +the first peer error, and concurrent same-kind watchers are bounded by the normal Busy rule. + +The older `WaitStopped` operation25 is retained as a send-context observer. It reports the +first cancellation cause, which can be local. If local Reset wins first, a subsequent peer +STOP cannot replace that context cause. Use operation29 for actual peer STOP, including +crossed shutdown; do not interpret the legacy local context result as remote evidence. + +ABI4 is the runtime gate for operation29. The managed loader rejects ABI3 or older before +admitting operations. Receipt revision3 is additional provenance, not a substitute for that +runtime gate. Export signatures and all structure sizes remain unchanged. + +### STOP and application reliable-minimum policies + +The pinned native `handleStopSendingFrame` deliberately clears its reliable size and sends +ordinary RESET_STREAM after STOP_SENDING. This is not an acknowledgement-driven optimization. +An earlier local reset's error remains authoritative if STOP arrives later, while the +subsequent actual reset can reduce reliable size to zero. The recorder reports these actual +frames; it never substitutes the earlier reliable boundary or received reset metadata. + +[Reliable-reset draft09 section5.4](https://www.ietf.org/archive/id/draft-ietf-quic-reliable-stream-reset-09.txt) +recommends ordinary RESET_STREAM in response to STOP; section5.2 permits application protocols +to impose minimum reliable sizes. +[WebTransport draft16 section4.4](https://www.ietf.org/archive/id/draft-ietf-webtrans-http3-16.txt) +requires header-sized reliable reset for WebTransport data streams. Generic QUIC correctness +alone does **not** establish an exception to that application requirement. + +This pinned backend currently has no native policy setting that preserves a minimum reliable +size after peer STOP. The new observation does not add such a policy or authorize a +WebTransport binding to accept ordinary resets as reliable-prefix confirmation. That use +requires an authoritative normative reconciliation or separately approved and qualified +native policy support. No QUIC protocol behavior or the three-file observation overlay is +changed here. + +### Late application-error cancellation + +An H3 ResetSend event can arrive while a body write still owns its lease. Attach a +one-shot `NativeQuicCancellation` to the request rather than waiting for the send +before attempting the conflicting `Reset` operation: + +```csharp +using var reset = new NativeQuicCancellation(); +var request = new NativeQuicRequest(timeout, body) +{ + Cancellation = reset +}; +Task writing = backend.StreamAsync( + stream, NativeQuicStreamOperation.Send, request, lifetimeToken).AsTask(); + +// When the application learns the mapped wire error: +await reset.CancelAsync(wireError); +NativeQuicCompletion sent = await writing; +``` + +`CancelAsync` publishes the full 62-bit error before invoking cancellation callbacks. +It awaits **only signalling callbacks**, not the native write or its body lease. +The callback uses the existing C `opcua_quic_cancel(operation, error)` export, so it +interrupts only the send direction and leaves the native prefix critical section intact. +Passing `reset.Token` separately is optional. The first control request wins; repeat +calls cannot overwrite its `ErrorCode`. Keep the control alive until its operation drains. + +The ordinary lifetime token continues using `CancellationErrorCode` unless the dynamic +control has already been requested. A cancellation already delivered to native code +remains authoritative: a later control request cannot replace that earlier wire error. +For a send that already completed, cancellation may lose the race without emitting any +reset. After draining, the host must use ordinary `Reset` if still required by stream state. +Never infer reset transmission from successful signalling. + +For H3: reconcile the actual terminal write bytes with operation20, then obtain +`WaitResetSent` **local** final/reliable/error evidence for operation22. Do not release +the H3 lease early, cancel the receive half or manufacture reset metadata. No native +ABI/export/library change is needed for this managed cancellation control. + +## Reproduction + +Use verified public Go1.27.2 and Zig0.17.0 Windows archives from `build\native-pins.json`. +No installer or global PATH/configuration change is required. `ToolRoot` contains +`go\bin\go.exe` and `zig\zig.exe`. `CacheRoot` is an existing writable Go/Zig cache; +`QuicSourceRoot` is the exact source tree from the checksum-verified module zip. +Reuse a reviewed tree instead of duplicating a full mirror. Every source file is compared +with the verified Go module, then only the three pinned observation files are overlaid. +Go forbids overlays directly in its module cache; an output-local small shim source tree +uses a junction to the reviewed QUIC tree with a stable `./quic-go` replacement. This +avoids embedding private source paths in native module build-info and makes no upstream +source mirror. The committed go.mod/go.sum remain canonical, without local replacement. + +```powershell +.\build\Build-Native.ps1 -ToolRoot $tools -CacheRoot $cache -QuicSourceRoot $quicSource ` + -OutputRoot $output -RuntimeIdentifier win-x64 +.\build\Build-Native.ps1 -ToolRoot $tools -CacheRoot $cache -QuicSourceRoot $quicSource ` + -OutputRoot $output -RuntimeIdentifier linux-x64 +.\build\Pack-Native.ps1 -ToolRoot $tools -CacheRoot $cache -QuicSourceRoot $quicSource ` + -OutputRoot $packageOutput -UnsignedDevelopment +``` + +The scripts verify executable/source/module/overlay pins, run Go vet, build with +`-trimpath -buildvcs=false -buildmode=c-shared`, restrict/inspect actual exports and +emit path-free per-RID receipts plus asset SHA256 sidecars.

The separate HTTP/3 engine +reuses this runtime rather than loading another Go image. + +The backend uses pinned quic-go **0.64.0**, Go **1.27.2** and Zig **0.17.0**, with only +the reviewed three-file exact-reset-09 **observation** overlay.

A successful +race stays successful. Resource handles require explicit asynchronous release; there is +no finalizer that closes unrelated resources. Stream release cannot race a pending job. + +For servers, `ListenAsync` creates a real UDP listener; the `Address` listener operation +returns its bound endpoint and `Accept` independently returns each authenticated connection. +Closing a listener does not close accepted connections. Its immutable policy supports +multiple application/key rules. New trust/revocation decisions require a fresh validated +snapshot and explicit closure of affected connections. Native X.509 verifies chain, +lifetime, usage and connector hostname; **CRL/OCSP fetching and online revocation are +not provided**, and must not be claimed by a policy provider. + +For an error learned after a send starts, set +`new NativeQuicRequest(timeout, body) { Cancellation = reset }`, where `reset` is a +caller-owned `NativeQuicCancellation`. Later `await reset.CancelAsync(wireError)` signals +the existing native cancellation entry without waiting for the body lease. Await the +send separately and inspect its actual result and `WaitResetSent` evidence. The first +requested/delivered cancellation remains authoritative; completed-send races may require +ordinary Reset afterward. Dispose the control only after the operation drains. + +ABI4 adds `WaitPeerStopped`, which observes an actual authenticated peer STOP_SENDING +even if local cancellation happened first. The older `WaitStopped` observes the first +send-context cause and is not sufficient for crossed shutdown. Actual STOP and reset +evidence remain distinct; no final/reliable size is invented for a STOP. + +**Application-policy limitation:** the pinned QUIC implementation responds to peer STOP +with ordinary RESET_STREAM, including after a reliable prefix was marked. This follows +reliable-reset draft09's transport guidance but does not establish an exception to +WebTransport draft16's application-level header minimum. There is currently no native +setting to preserve a minimum reliable size after peer STOP. See `native/NATIVE_ABI.md` +before selecting this backend for a protocol with that requirement; the observer does +not add such a policy or turn ordinary resets into reliable-prefix confirmation. + +## Deployment and ownership + +Only **win-x64** and **glibc linux-x64** are included. The source-adoption execution +matrix is serviced Windows/.NET and Linux glibc 2.38/2.39. The Linux compiler target is +glibc 2.28; this is **not minimum-host execution evidence**.

Never call `NativeLibrary.Free`, `FreeLibrary` or `dlclose` on it. +Restart to upgrade. `NativeQuicLibrary` checks absolute trusted paths, SHA256 and ABI +layouts; it never searches PATH.

Direction is relative +to the **flow opener**, not the Publisher or transport initiator: +`AcceptorToOpener` also supports a remotely opened publishing flow. +`PubSubConnectionBuilder.WithDataChannel(...)` provides the same nested +configuration API. A bound context needs no connection Address; a +connector-backed `IDataChannelPubSubFlowProvider` can use the standard +Address to locate the actual endpoint. + +DI uses `IPubSubBuilder.AddDataChannelTransport(carrierKind, provider)` for +a caller-owned provider, or its factory overload for a DI-owned provider. +Custom providers return an actual ready `DataChannelPubSubFlow`; they +must clean up failed or cancelled establishment. An optional +`IDataChannelPubSubGrantProvider` obtains a fresh Session grant through +the model-control API. The default configured path never creates a +Session or reads an address space. + +The context-backed accept provider exclusively owns `AcceptAsync` for its +context, routing by exact resource and payload protocol with bounded +pending admission. A host that also accepts other application flows +must use its shared router instead; `Opc.Ua.PubSub.Server` supplies a +server-router adapter. Disposing a transport closes only its flow, not +unrelated flows or shared Client/Server Services. After context loss a +connector must acquire a new authenticated context and fresh flow. + +Several writers may share one flow. Separate resources, permissions, +queue budgets, delivery contracts, or lifetimes require separate flows. +ChannelId never replaces PublisherId, WriterGroupId, or DataSetWriterId. +The adapter validates the negotiated descriptor before enabling groups, +preserves every encoded byte, and retains received message credit until +decoding and sink processing finish. UADP chunking/reassembly remains +Part 14 processing. Opaque flows are not a PubSub encoding. +`AllowQueueExpiry=true` is rejected until a Publisher-side policy can preserve +or recover metadata/key-frame/delta dependencies. The adapter never silently +disables requested expiry or parses and rewrites NetworkMessages to compensate. +An orderly remote END drains accepted messages through reader delivery before +disconnect notifications pause the connection. Directional EOF alone does not +disconnect a still-open duplex flow; its remaining direction and control stay +available. Authorization and protocol faults still take effect immediately. + +Carrier confidentiality needs neither a broker nor an SKS. Existing +UADP signing/encryption remains available when explicitly configured +with its normal key provider; JSON cannot silently satisfy a configured +UADP message-security requirement. + +For live revisions, directional end, and flow diagnostics, a transport +observer can retain the concrete `DataChannelPubSubTransport` created by +the factory and use its borrowed `Channel` property after opening. The +property is null before opening and after closing; ownership remains +with the transport. Session-authorized updates still need the normal +model-control authorization. + +Raw-byte diagnostics belong at `IPubSubTransport.SendAsync` and +`ReceiveAsync`, after Part 14 encoding/security/chunking. A decorator +must preserve the yielded frame lifetime and forward +`IPubSubEncodingTransport.EncodingProfileUri` and +`MaxNetworkMessageSize`; otherwise it hides negotiated capabilities. + ## Target frameworks `net48`, `net8.0`, `net9.0`, `net10.0`. diff --git a/src/Opc.Ua.PubSub/Security/AesCtrNonceLayout.cs b/src/Opc.Ua.PubSub/Security/AesCtrNonceLayout.cs index c4094d52cd..eec9509db2 100644 --- a/src/Opc.Ua.PubSub/Security/AesCtrNonceLayout.cs +++ b/src/Opc.Ua.PubSub/Security/AesCtrNonceLayout.cs @@ -251,24 +251,18 @@ public static ulong ToLow64(in PublisherId publisherId) private static ulong ProjectString(string value) { Span buffer = stackalloc byte[PublisherIdLength]; - int written = 0; #if NET6_0_OR_GREATER - written = SystemEncoding.UTF8.GetBytes(value.AsSpan(), buffer); - if (written < PublisherIdLength) - { - buffer[written..].Clear(); - } + // The extra UTF-16 unit preserves a surrogate pair crossing the eight-byte prefix. + Span utf8 = stackalloc byte[SystemEncoding.UTF8.GetMaxByteCount(PublisherIdLength + 1)]; + int written = SystemEncoding.UTF8.GetBytes( + value.AsSpan(0, Math.Min(value.Length, PublisherIdLength + 1)), utf8); + ReadOnlySpan prefix = utf8[..Math.Min(written, PublisherIdLength)]; #else byte[] utf8 = SystemEncoding.UTF8.GetBytes(value); - int copy = utf8.Length < PublisherIdLength ? utf8.Length : PublisherIdLength; - utf8.AsSpan(0, copy).CopyTo(buffer); - if (copy < PublisherIdLength) - { - buffer[copy..].Clear(); - } - written = copy; + ReadOnlySpan prefix = utf8.AsSpan(0, Math.Min(utf8.Length, PublisherIdLength)); #endif - _ = written; + prefix.CopyTo(buffer); + buffer[prefix.Length..].Clear(); return BinaryPrimitives.ReadUInt64LittleEndian(buffer); } diff --git a/src/Opc.Ua.PubSub/Transports/DataChannels/DataChannelContextPubSubFlowProvider.cs b/src/Opc.Ua.PubSub/Transports/DataChannels/DataChannelContextPubSubFlowProvider.cs new file mode 100644 index 0000000000..fafa2bdb3c --- /dev/null +++ b/src/Opc.Ua.PubSub/Transports/DataChannels/DataChannelContextPubSubFlowProvider.cs @@ -0,0 +1,390 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

The content uses neutral example identifiers and test values. +It contains no specification prose, third-party reference implementation, private +fixture catalog, absolute file path or environment-dependent fixture lookup. + +Expected bytes are assembled only from **fixed hexadecimal headers** and literal +JSON or binary bodies. Header lengths are frozen literals, not calculated by the +codec or generated at test time. Typed expected controls are constructed +independently of those bytes.

The detailed tests also cover bounds, UTF-8, numeric and enum values, + member ordering, stream segmentation/EOF and body ownership. + +The opaque sample is `k9!`. The UADP-shaped sample uses publisher `0x3412`, writer +group `0x2244`, group version `0x01020304`, network-message number `0x0506`, +sequence `0x0708`, writer `0x0910` and one Int32 field `-19`. The JSON-shaped +sample uses publisher `bench-7`, writer `57` and value `-19`, with intentional +outside whitespace. These are byte-preservation specimens, **not** Part 14 +validation or authentication oracles. A separate all-byte-values case checks +that no inner framing, decoding or normalization is introduced. + +UASC specimens contain only the plaintext codec input.
