From 894c4a6fd95c9ea06bc78cf14702a7fb2d06ed09 Mon Sep 17 00:00:00 2001 From: Marc Schier Date: Mon, 15 Jun 2026 20:07:11 +0200 Subject: [PATCH 001/125] Phase 0: Scaffolding for Part 14 PubSub reimplementation Lays the groundwork for replacing the current Opc.Ua.PubSub library (v1.04-era, non-AOT, Newtonsoft-based) with a modern, AOT-clean, fluent, DI-integrated, Part 14 v1.05.07-compliant stack. Library scaffolding: - Add Libraries/Opc.Ua.PubSub.Udp/ (UDP transport, Part 14 sec.7.3.2). - Add Libraries/Opc.Ua.PubSub.Mqtt/ (MQTT transport, Part 14 sec.7.3.4). - Add Libraries/Opc.Ua.PubSub.Server/ (address-space integration, Part 14 sec.9). - All three are net472/net48/netstandard2.1/net8/net9/net10 multi-targeted. - IsAotCompatible=true on net10; EnableConfigurationBindingGenerator=true; MIT header on every file; CLSCompliant(false) per repo convention. Test scaffolding: - Rename existing Tests/Opc.Ua.PubSub.Tests to Tests/Opc.Ua.PubSub.Tests.Legacy (kept for reference; excluded from UA.slnx). Will be deleted in a later phase. - Add fresh Tests/Opc.Ua.PubSub.Tests/, plus parallel test projects for Udp, Mqtt, Server transports and a Bench project (BenchmarkDotNet). - All test projects target the Tests TFM matrix (net472;net48;net8;net9;net10) and use NUnit + Moq + coverlet as per repo convention. Solution wiring: - Add the 3 new lib + 5 new test projects to UA.slnx; old Tests path entry replaced by the new tests entries. Existing Libraries/Opc.Ua.PubSub library is untouched (transports/encoders will be modernised and migrated out in subsequent phases; the existing project continues to build with 0 warnings so the ConsoleReferencePublisher/Subscriber samples and consumers stay green throughout the migration). Verification: - dotnet restore UA.slnx and dotnet build UA.slnx both succeed (0 errors; warnings unchanged from baseline). - All 8 new csprojs build clean on net10 (0 warnings). ---

Sets the contract surface every subsequent phase (UADP encoder, JSON encoder, transports, SKS, server) hangs off. New namespaces under Libraries/Opc.Ua.PubSub: - StateMachine: PubSubState transition tracker (Part 14 sec.6.2.1, sec.9.1.10), parent-child cascade per sec.9.1.3.5, all 5 states, transition reason enum, event args, component-kind enum. - Diagnostics: IPubSubDiagnostics, PubSubDiagnostics default impl, counter enum with all Part 14 sec.9.1.11 counters. - MetaData: IDataSetMetaDataRegistry + DataSetMetaDataRegistry default impl + key/match-result types (Part 14 sec.5.2.3, sec.6.2.9.4, sec.7.2.4.6.4). - Encoding: INetworkMessageEncoder/Decoder, abstract PubSubNetworkMessage/PubSubDataSetMessage records, PublisherId discriminated union, field encoding/message type enums, context object. - Transports: IPubSubTransport, IPubSubTransportFactory, frame/address/direction types (factory keyed by TransportProfileUri, per plan section 4.10). - Security: IPubSubSecurityPolicy, IPubSubSecurityKeyProvider, ISecurityTokenWindow, INonceProvider, PubSubSecurityKey, PolicyUri constants (Part 14 sec.7.2.4.4.3, sec.8). - Scheduling: IPubSubScheduler + PubSubSchedule (Part 14 sec.6.4.1). - DataSets: IPublishedDataSet, IPublishedDataSetSource, IDataSetFieldSampler, ISubscribedDataSetSink, PublishedDataSetSnapshot. - Groups, Connections, Application: IDataSetWriter, IWriterGroup, IDataSetReader, IReaderGroup, IPubSubConnection, IPubSubApplication, PubSubApplicationOptions. - Configuration: IPubSubConfigurationStore + PubSubConfigurationSnapshot + change event args. Tests in Tests/Opc.Ua.PubSub.Tests: - StateMachine/PubSubStateMachineTests.cs (57 tests, 100% line and branch coverage) - Diagnostics/PubSubDiagnosticsTests.cs (30 tests, all 3 diagnostics levels exercised) - MetaData/DataSetMetaDataRegistryTests.cs (16 tests, all 4 MetaDataMatchResult outcomes covered) Every test fixture and method carries TestSpec attributes linking to the Part 14 clause it validates, per plan section 6.2 traceability convention. Polyfill notes: - Multi-TFM (net472/net48/netstandard2.1/net8/net9/net10) requires using longhand argument-null checks instead of ArgumentNullException.ThrowIfNull (.NET 6+ only). - Array.Clear(arr) single-arg overload guarded by #if NET5_0_OR_GREATER; non-generic Enum.GetValues used on older TFMs. Verification: - Libraries/Opc.Ua.PubSub multi-TFM build: 0 warnings, 0 errors. - Tests/Opc.Ua.PubSub.Tests multi-TFM build: 0 errors (2 pre-existing NU1701 warnings from external Microsoft.Extensions.TimeProvider.Testing package on net48 are unchanged). - All 103 new tests pass on net8/net9/net10. - Full UA.slnx build: 0 errors (676 unrelated pre-existing warnings unchanged). --- .../Application/IPubSubApplication.cs | 90 +++ .../Application/PubSubApplicationOptions.cs | 73 ++

Code is fully verified together (multi-TFM clean, 408 tests pass, coverage gates met). Phase 2 (UADP, Part 14 sec.7.2.4 and Annex A.2): - 19 production files in Libraries/Opc.Ua.PubSub/Encoding/Uadp/. - Flag enums (UadpFlags, ExtendedFlags1/2, GroupFlags, DataSetFlags1/2) with Combine/Split helpers. - Sealed records UadpNetworkMessage / UadpDataSetMessage inheriting Phase 1 abstract bases. - UadpEncoder + UadpBinaryWriter (ref-struct, Span-based, ArrayPool-backed) + UadpFieldEncoder (3 field-encoding modes per sec.7.2.4.5.4). - UadpDecoder + UadpBinaryReader + UadpFieldDecoder following the 9-step decoder algorithm in the research artifact sec.2. - UadpChunker (length-bounded splitter) + UadpReassembler (TTL-bounded, keyed by (PublisherId, WriterGroupId, NetworkMessageNumber), drops duplicates and incompatible offsets) per sec.7.2.4.4.4. - UadpDiscoveryRequestMessage / UadpDiscoveryResponseMessage / UadpDiscoveryCoder routed from main encoder/decoder via ExtendedFlags2 discovery bits, per sec.7.2.4.6.4/.7/.8/.9. - 10 NUnit fixtures with [TestSpec] coverage. 146 UADP-specific tests, 86 percent line coverage on the Uadp namespace. Phase 3 (JSON on System.Text.Json, Part 14 sec.7.2.5 and Annex A.3): - 12 production files in Libraries/Opc.Ua.PubSub/Encoding/Json/. - All 4 encoding modes (Reversible, NonReversible, Compact, Verbose); all 4 DataSetMessageType variants (ua-keyframe, ua-deltaframe, ua-event, ua-keepalive). - SingleMessageMode for MQTT DataSetWriter-specific topics (Annex A.3.3). - JsonMetaDataMessage for ua-metadata envelopes (sec.7.2.5.5). - JsonBufferWriter polyfill for net48/netstandard2.0 (ArrayBufferWriter internal there). - ZERO Newtonsoft.Json dependency in new code; old Newtonsoft-backed encoder/decoder kept untouched for the Phase 9 shim. - 74 NUnit tests including byte-for-byte parity tests against the legacy Newtonsoft encoder (JsonNewtonsoftParityTests) with three documented STJ-vs-Newtonsoft divergences: Variant envelope key remap (UaType/Value vs Type/Body) handled at the boundary, double formatting (shortest-round-trippable), property ordering (canonicalised pre-compare). 86 percent line coverage on the Json namespace. Phase 4 (Configuration validator + XML compat, Part 14 sec.6.2 / sec.9.1.3): - 8 production files in Libraries/Opc.Ua.PubSub/Configuration/. - PubSubConfigurationSnapshot extended with 6 O(1) lookup indices (ConnectionsByName, WriterGroupsById, DataSetWritersById, ReaderGroupsByName, DataSetReadersByName, PublishedDataSetsByName). - PubSubConfigurationValidator with rules covering: unique-id checks, supported TransportProfileUri, address scheme/transport match, SecurityMode<->SecurityGroupId<->SecurityKeyServices rules (sec.6.2.5.4), KeyFrameCount>0 warning, DatagramConnectionTransport2DataType v2-preference info. - PubSubConfigurationIssue / IssueSeverity / ValidationResult / Exception types with PSCxxxx error codes. - XmlPubSubConfigurationStore for IPubSubConfigurationStore using stack XmlEncoder/XmlDecoder directly (no legacy helper dependency). Atomic write-temp-then-move. - 86 NUnit tests, 93 percent line coverage on Phase 4 types. - Round-trip-tested against the two golden XML configurations from the legacy test project (now copied into the new tests project). Polyfill notes: - net472/net48 lack Guid(ReadOnlySpan) and Guid.TryWriteBytes(Span); UadpBinaryReader/Writer use ToByteArray + System.Buffer.BlockCopy. - net472/net48 lack RandomNumberGenerator.Fill; UadpChunkingTests now use the instance-API GetBytes. - net48/netstandard2.0 ArrayBufferWriter is internal; JsonBufferWriter is a custom IBufferWriter on ArrayPool. Verification: - Library multi-TFM build (net472/net48/netstandard2.1/net8/net9/net10): 0 warnings, 0 errors. - 408 tests pass (Phase 1 + 2 + 3 + 4 + cross-phase) on net10. - Full UA.slnx build: 0 errors, 458 warnings (all pre-existing in unrelated test projects). --- .../PubSubConfigurationException.cs | 108 + .../Configuration/PubSubConfigurationIssue.cs | 112 +

Both libraries implement Phase 1's IPubSubTransport / IPubSubTransportFactory abstractions. Phase 5 -- Opc.Ua.PubSub.Udp (Part 14 sec.7.3.2): - 8 production files. UdpEndpointParser detects multicast / broadcast / subnet-broadcast / unicast addresses (sec.7.3.2.2 / .3) for IPv4 and IPv6; rejects non-opc.udp schemes, malformed IPv6, port-out-of-range. - UdpDatagramTransport: async-first using Socket.ReceiveFromAsync / SendToAsync (no APM); ArrayPool-backed receive loop is allocation-free in steady state; Channel bounded queue; IPv4 + IPv6 + multicast group join with explicit NetworkInterface selection; Windows SIO_UDP_CONNRESET silenced. - UdpMessageRepeater: optional MessageRepeatCount / MessageRepeatDelay retransmission per sec.6.4.1. - UdpNetworkInterfaceResolver: by-name, by-IP, fallback to first up-and-running. - UdpPubSubTransportFactory implements IPubSubTransportFactory keyed on Profiles.PubSubUdpUadpTransport; reads the NetworkInterface property from connection.ConnectionProperties or directly from URL. - UdpTransportOptions bindable from IConfiguration. Phase 6 -- Opc.Ua.PubSub.Mqtt (Part 14 sec.7.3.4): - 17 production files. MqttTopicBuilder enforces sec.7.3.4.7.3 / .4 schema; rejects MQTT wildcards (#, +) in user-supplied tokens. - MqttBrokerTransport implements IPubSubTransport; subscribes only to the narrowest configured topics; sets ContentType (application/json or application/opcua+uadp) on MQTT 5; auto-applies Retain when Topics.RetainMetaDataMessages is true and topic matches the metadata pattern; QoS mapping (sec.7.3.4.5). - IMqttClientAdapter wraps MQTTnet v4 / v5 API differences. MqttClientAdapter compiles two arms (#if NET8_0_OR_GREATER chooses v5 MqttClientFactory + MqttClientOptionsBuilder; older TFMs use v4 MqttFactory). Both arms produce identical observable behaviour through the wrapper interface. - MqttPubSubTransportFactory implements IPubSubTransportFactory; takes the TransportProfileUri at construction so Phase 9 can register one factory per profile (Json vs UADP). - All credentials sourced via PasswordSecretId (looked up in ISecretStore at runtime); never plain Password property -- security check enforced by tests. - MqttConnectionOptions / MqttTlsOptions / MqttTopicOptions all bindable from IConfiguration. - Added MQTTnet.Server v5 reference to Directory.Packages.props for the embedded broker integration test (modern TFMs only -- legacy TFMs use the v4-pinned MQTTnet which already includes the broker). Verification: - Phase 5 multi-TFM build (net472/net48/netstandard2.1/net8/net9/net10): 0 warnings, 0 errors. - Phase 6 multi-TFM build: 0 warnings, 0 errors. Both MQTTnet v4 (net48 path) and v5 (net10 path) verified. - Phase 5: 95 NUnit tests pass on net10. Phase 6: 100 tests pass on net10. - Phase 5 line coverage: 79.8 percent on Opc.Ua.PubSub.Udp.* (the 0.2 percent gap to 80 percent is exclusively in defensive 'catch (SocketException) { LogDebug }' blocks around socket-option setting; these handlers fire only on environmental issues a unit test cannot reasonably reproduce without a Socket abstraction layer). - Phase 6 line coverage: 87.2 percent on Opc.Ua.PubSub.Mqtt.*. - Full UA.slnx build: 0 errors, 458 unrelated pre-existing warnings (unchanged from before). Out of scope (per phase boundaries): - Phase 7 owns security wrapping (signing/encryption); Phase 5/6 transports just shuttle bytes. - Phase 9 owns DI extension methods (UseUdpTransport, UseMqttTransport). --- Directory.Packages.props | 1 + .../Opc.Ua.PubSub.Mqtt/IMqttClientFactory.cs | 63 ++ .../Internal/IMqttClientAdapter.cs | 117 +++ .../Internal/MqttClientAdapter.cs | 424

Files: - Security/Policies/PubSubNonePolicy.cs / PubSubAes128CtrPolicy.cs / PubSubAes256CtrPolicy.cs / PubSubSecurityPolicyRegistry.cs (singleton policies; HMAC-SHA-256 for signing; AES-128/256-CTR via AesCtrTransform; CryptographicOperations.FixedTimeEquals for timing-safe verify with polyfill SecureComparison for net48). - Security/Internal/AesCtrTransform.cs (manual CTR using Aes ECB on counter blocks; nonce(12)||counter(4 BE); both per-spec and full-16-byte-counter overloads for NIST KAT). - Security/Internal/HmacSha256.cs / SecureComparison.cs (polyfills: HMACSHA256.HashData and CryptographicOperations.FixedTimeEquals are net5+ only). - Security/AesCtrNonceLayout.cs (Table 156 layout helpers; PublisherId-to-low-64 projection for stable nonce composition across PublisherId types). - Security/RandomNonceProvider.cs (RandomNumberGenerator-backed, instance-API for net48 compat, thread-safe via Lock). - Security/SecurityTokenWindow.cs (ISecurityTokenWindow impl with per-token sequence ring + global nonce-fingerprint set; bounded; thread-safe). - Security/PubSubSecurityKeyRing.cs / StaticSecurityKeyProvider.cs (key lifecycle without SKS pull; Phase 8 adds the dynamic provider). - Security/UadpSecurityFlagsEncodingMask.cs / UadpSecurityHeader.cs (Annex A.2.1.6 / A.2.2.5 layouts). - Security/UadpSecurityWrapper.cs (the integration point; WrapAsync/TryUnwrapAsync with the simple prefix+payload split contract; appends signature over prefix||header||ciphertext per spec). Tests (Tests/Opc.Ua.PubSub.Tests/Security/): - 12 fixtures, 109 assertions; all spec-tagged with [TestSpec(Part=14, Clause=...)]. - NIST SP 800-38A F.5.1 known-answer test for AES-128-CTR (Tests/Security/Internal/AesCtrTransformTests.cs). - Replay rejection, nonce-reuse rejection, unknown-token rejection, tampered-ciphertext rejection. Verification: - Library multi-TFM build: 0 warnings, 0 errors. - 517 PubSub tests pass on net10 (517 = Phases 1-7 cumulative). - Coverage on Phase 7 types: 94.63 percent line coverage. - Full UA.slnx build: 0 errors. Deviation noted: UadpSecurityWrapper currently passes header.SecurityTokenId as the sequenceNumber to ISecurityTokenWindow.TryAccept because the real per-DataSetMessage sequence is inside the still-encrypted payload at that point. Replay protection therefore relies on the spec-mandated nonce-uniqueness control.

Files (13 production, 8 tests): - Sks/SksKeyRequest.cs / SksKeyResponse.cs / SksSecurityGroup.cs (common record types; Response.Unpacked splits packed ByteStrings into PubSubSecurityKey instances via the resolved policy lengths). - Sks/ISecurityKeyService.cs / SksAvailabilityChangedEventArgs.cs / OpcUaSecurityKeyServiceClient.cs / OpcUaSksException.cs (OPC UA client that calls PubSubKeyServiceType.GetSecurityKeys via a ManagedSession; lazy session lifecycle; surfaces availability transitions). - Sks/PullSecurityKeyProvider.cs / PullSecurityKeyProviderOptions.cs (IPubSubSecurityKeyProvider implementation backed by PubSubSecurityKeyRing; scheduler-driven background refresh runs on a separate task; GetCurrentKeyAsync never blocks publish; opportunistic refresh for unknown future tokens; gracefully degrades when SKS unavailable). - Sks/IPubSubKeyServiceServer.cs / InMemoryPubSubKeyServiceServer.cs (server side; AddSecurityGroup with policy URI validation; GetSecurityKeysAsync with caller identity check; thread-safe via Lock). - Sks/SksKeyGenerator.cs (RandomNumberGenerator-backed key material generation; per-policy lengths from IPubSubSecurityPolicy). - Sks/SksMethodHandler.cs (sync-to-async bridge for hosting the SKS via the current stack method-handler API; Phase 10 will replace this with the async NodeManager path; documented in XML doc). Tests (Tests/Opc.Ua.PubSub.Tests/Security/Sks/): - 8 fixtures with FakeSecurityKeyService test double for the pull provider. - All replay / nonce-reuse / unknown-token / unknown-group / duplicate-group / unsupported-policy paths covered. Verification: - Library multi-TFM build (net472/net48/netstandard2.1/net8/net9/net10): 0 warnings, 0 errors. - 578 PubSub tests pass on net10 (cumulative Phases 1-8). Csproj changes: - Added ProjectReference to Libraries/Opc.Ua.Client for the SKS pull-client's ManagedSession usage. - Added true on net472/net48 to match Opc.Ua.Client's existing suppression of Microsoft.Extensions.Http.Resilience / Telemetry / AmbientMetadata 'doesn't support net48/net472' transitive warnings (same TODO to drop when the package matrix stops warning). --- Libraries/Opc.Ua.PubSub/Opc.Ua.PubSub.csproj | 12 + .../Security/Sks/IPubSubKeyServiceServer.cs | 119 +++++ .../Security/Sks/ISecurityKeyService.cs | 75 +++ .../Sks/InMemoryPubSubKeyServiceServer.cs | 412 ++++++++++++++++ .../Sks/OpcUaSecurityKeyServiceClient.cs | 397 +++++++++++++++ .../Security/Sks/OpcUaSksException.cs | 115 +++++ .../Security/Sks/PullSecurityKeyProvider.cs | 460 ++++++++++++++++++ .../Sks/PullSecurityKeyProviderOptions.cs | 75 +++ .../Sks/SksAvailabilityChangedEventArgs.cs | 90 ++++ .../Security/Sks/SksKeyGenerator.cs | 121 +++++ .../Security/Sks/SksKeyRequest.cs | 61 +++ .../Security/Sks/SksKeyResponse.cs | 210 ++++++++ .../Security/Sks/SksMethodHandler.cs | 189 +++++++ .../Security/Sks/SksSecurityGroup.cs | 152 ++++++ .../Security/Sks/FakeSecurityKeyService.cs | 115 +++++ .../InMemoryPubSubKeyServiceServerTests.cs | 236 +++++++++ .../Sks/OpcUaSecurityKeyServiceClientTests.cs | 291 +++++++++++ .../Sks/PullSecurityKeyProviderTests.cs | 349 +++++++++++++ .../Security/Sks/SksKeyGeneratorTests.cs | 119 +++++ .../Security/Sks/SksKeyRequestTests.cs | 71 +++ .../Security/Sks/SksKeyResponseTests.cs | 179 +++++++ .../Security/Sks/SksMethodHandlerTests.cs | 228 +++++++++ 22 files changed, 4076 insertions(+) create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/IPubSubKeyServiceServer.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/ISecurityKeyService.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/InMemoryPubSubKeyServiceServer.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/OpcUaSecurityKeyServiceClient.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/OpcUaSksException.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/PullSecurityKeyProvider.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/PullSecurityKeyProviderOptions.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/SksAvailabilityChangedEventArgs.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/SksKeyGenerator.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/SksKeyRequest.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/SksKeyResponse.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/SksMethodHandler.cs create mode 100644 Libraries/Opc.Ua.PubSub/Security/Sks/SksSecurityGroup.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/FakeSecurityKeyService.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/InMemoryPubSubKeyServiceServerTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/OpcUaSecurityKeyServiceClientTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/PullSecurityKeyProviderTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/SksKeyGeneratorTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/SksKeyRequestTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/SksKeyResponseTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Security/Sks/SksMethodHandlerTests.cs diff --git a/Libraries/Opc.Ua.PubSub/Opc.Ua.PubSub.csproj b/Libraries/Opc.Ua.PubSub/Opc.Ua.PubSub.csproj index aaaa5e9ddd..f49a633b54 100644 --- a/Libraries/Opc.Ua.PubSub/Opc.Ua.PubSub.csproj +++ b/Libraries/Opc.Ua.PubSub/Opc.Ua.PubSub.csproj @@ -9,6 +9,17 @@ true enable + + + true + @@ -17,6 +28,7 @@ + diff --git a/Libraries/Opc.Ua.PubSub/Security/Sks/IPubSubKeyServiceServer.cs b/Libraries/Opc.Ua.PubSub/Security/Sks/IPubSubKeyServiceServer.cs new file mode 100644 index 0000000000..e8598e7022 --- /dev/null +++ b/Libraries/Opc.Ua.PubSub/Security/Sks/IPubSubKeyServiceServer.cs @@ -0,0 +1,119 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

binds IPubSubDiagnostics counters to Diagnostics.TotalInformation.* Variables based on PubSubServerOptions.DiagnosticsExposure. - IPubSubServerBuilder + AddPubSub on IOpcUaServerBuilder; throws InvalidOperationException if Phase 9's AddPubSub has not been called first (the IPubSubApplication registration is mandatory). - WithSecurityKeyServiceServer convenience registers an InMemoryPubSubKeyServiceServer as IPubSubKeyServiceServer. - Documented gap: AddConnection/RemoveConnection/SetConfiguration mutation methods return BadNotImplemented because Phase 9 IPubSubApplication is a read-only runtime surface; a future phase will introduce a mutable configuration API. - 6 test fixtures, 60 tests, 90.26 percent line coverage. Phase 13 P3-S1 -- JsonEncodingMode v1.05.06 vocabulary (closes #3609): - Replaced Opc.Ua.PubSub.Encoding.Json.JsonEncodingMode 4-value enum (Reversible/NonReversible/Compact/Verbose) with v1.05.06 3-value enum (Verbose/Compact/RawData). - DROPPED Reversible and NonReversible outright (no [Obsolete] aliases) per user direction. - Updated every call site in Encoding/Json/* and the Phase 9 shim layer. - JsonVariantEncoder.IsReversible renamed WrapsInVariantEnvelope. - JSON test fixtures updated to use the new names; tests deduped to 3 modes; new RawData test cases added. - JsonNewtonsoftParityTests maps new <-> legacy enum (Verbose<->Reversible, Compact<->NonReversible) for backwards on-wire compatibility verification. - Docs/migrate/2.0.x/pubsub.md stub created with the rename table. Phase 13 P3-S2 -- UADP RawData padding (closes #3566): - UadpBinaryWriter.WriteRawScalar overload pads String/ByteString/XmlElement to FieldMetaData.MaxStringLength (writes fixed-length byte block with trailing NULs, length prefix suppressed) and arrays to FieldMetaData.ArrayDimensions per Part 14 v1.05.06 sec.7.2.4.5.11. - Symmetric UadpBinaryReader.ReadRawScalar reads fixed-length, trims trailing NULs to recover the original payload on String/ByteString/XmlElement; arrays read fixed-count then validate against expected. - UadpFieldEncoder.EncodeRawFields and EncodeDeltaFrame's RawData arm now pass the FieldMetaData bounds through. - New validator rule PSC0025 in PubSubConfigurationValidator: warns when DataSetFieldContentMask.RawData is selected but the field has no MaxStringLength/ArrayDimensions (breaks interop with strict v1.05.06 subscribers). - New Tests/Opc.Ua.PubSub.Tests/Encoding/Uadp/UadpRawDataPaddingTests.cs with 12 spec-tagged tests including a direct repro of issue #3566's configuration. - 4 new validator tests for PSC0025. - Docs/migrate/2.0.x/pubsub.md appended with the padding behaviour change. Csproj changes: - Libraries/Opc.Ua.PubSub.Server/Opc.Ua.PubSub.Server.csproj: added SuppressTfmSupportBuildWarnings=true on net472/net48 to match the same suppression on Libraries/Opc.Ua.PubSub.csproj and Libraries/Opc.Ua.Client.csproj (transitive Microsoft.Extensions.Http.Resilience / Telemetry don't declare net48 support but ship net462 assets).

Sample apps: - Applications/ConsoleReferencePublisher rewritten to Host.CreateApplicationBuilder + AddPubSubPublisher fluent API. <=200 LOC Program.cs split across PublisherConfigurationBuilder + SampleDataSetSource. System.CommandLine flags: --profile {udp-uadp|mqtt-uadp|mqtt-json}, --config-file, --publisher-id, --writer-group-id, --data-set-writer-id, --endpoint, --interval. PublishAot=true on net10. - Applications/ConsoleReferenceSubscriber rewritten to Host.CreateApplicationBuilder + AddPubSubSubscriber fluent API. ConsoleLoggingSink subscribes to received DataSetMessages and logs to console. SubscriberConfigurationBuilder constructs the configuration declaratively. - Both samples drop Serilog; switch to Microsoft.Extensions.Logging.Console. - Both samples updated READMEs with Quick-Start, XML-config-mode, fluent-builder walkthrough, and AOT publish instructions. AOT validation: - dotnet publish -c Release -r win-x64 of both samples and Opc.Ua.Aot.Tests yields 0 IL2026 / IL3050 / IL3051 warnings. - Both published exes start cleanly on win-x64 with --profile udp-uadp. AOT test coverage: - Tests/Opc.Ua.Aot.Tests/PubSubAotTests.cs adds 6 TUnit tests covering fluent builder construction (UDP + MQTT broker), XML config round-trip, publisher start/stop lifecycle, and UADP + JSON network-message round-trip. - Total AOT test count: 84 -> 90, all passing under SourceGenerated AOT engine. Notes: - Subscriber DataSetReader requires MessageReceiveTimeout > 0 (PSC0041) - sample now sets 5000 ms. - DatagramReaderGroupTransportDataType does not exist in schema; subscriber omits TransportSettings on UDP ReaderGroup (broker profiles use BrokerDataSetReaderTransportDataType per-reader). - ApplicationId is derived from configuration in PubSubApplication.ResolveApplicationId; tests assert non-empty rather than exact string.

Create an instance of the [UaPubSubApplication Class](../../Docs/PubSub.md#uapubsubapplication-class) using the configuration data from step 1. - - ```csharp - // Create an instance of UaPubSubApplication - UaPubSubApplication uaPubSubApplication = UaPubSubApplication.Create(pubSubConfiguration); - ``` - -3. Provide the data to be published based on the configuration of published data sets. This step is described in the [Publisher Data](#publisher-data) section. -4. Start PubSub application - - ```csharp - // Start the publisher - uaPubSubApplication.Start(); - ``` - -After this step the Publisher will publish data as configured. - -### Publisher Configuration - -The Publisher configuration is a subset of the [PubSub Configuration](../../Docs/PubSub.md#pubsub-configuration). A functional *Publisher* application needs to have a configuration (*PubSubConfigurationDataType* instance) that contains a list of published data sets (*PublishedDataSetDataType* instances) and at least one connection (*PubSubConnectionDataType* instance) with at least one writer group configuration (*WriterGroupDataType* instance). The writer group contains at least one data set writer (*DataSetWriterDataType* instance) pointing to a published data set from the current configuration. - -The diagram shows the subset of classes involved in an *OPC UA Publisher* configuration. - -![PublisherConfigClasses](../../Docs/Images/PublisherConfigClasses.png) - -### Publisher Data - -The [UaPubSubApplication Class](../../Docs/PubSub.md#uapubsubapplication-class) provides a property of type [IUaPubSubDataStore](../../Docs/PubSub.md#iuapubsubdatastore-interface) called DataStore. In **ConsoleReferencePublisher** there is no custom implementation provided for *IUaPubSubDataStore* therefore the pub sub application object is initialized using the default implementation of this interface, an instance of *UaPubSubDataStore*. - -The code responsible for generating the data values to be published is located in the [PublishedValuesWrites](/PublishedValuesWrites.cs) file from the **ConsoleReferencePublisher** project. It maintains a list of all the fields from the table below and uses a timer for writing the values to *UaPubSubApplication.DataStore* using the *WritePublishedDataItem*() method from *DataStore* class. The data values simulator component is initialized like: - - // Start values simulator - PublishedValuesWrites valuesSimulator = new PublishedValuesWrites(uaPubSubApplication); - valuesSimulator.Start(); - -The **Publisher** component from **ConsoleReferencePublisher** application will use the data generated by *PublishedValuesWrites* to create the *NetworkMessages* that will be published as configured in [Publisher Configuration](#publisher-configuration). - -Note: -The current PubSub implementation only supports *PublishedDataItemsDataType* as *DataSetSource* of a *PublishedDataSetDataType* from the configuration. *Events* will be added in a future version. - -The **ConsoleReferencePublisher** application is configured to use the following data sets and will generate values as specified in the table below if the default configuration method is used: - -#### PublishedDataSet 'Simple' - NamespaceIndex = 2 - -| Name | DataType | ValueRank |Behavior | -|--|--|--|--| -|BoolToggle |Boolean |Scalar |Toggles every 3 seconds| -|Int32|Int32|Scalar |Counts (1 per second) from 0 to 10,000 and then resets| -|Int32Fast|Int32Fast|Scalar |Counts (100 per second) from 0 to 10,000 and then resets| -|DateTime|DateTime|Scalar |Current time refreshed with every packet sent| - -The *CreatePublishedDataSetSimple*() method from [Program.cs](Program.cs) creates a *PublishedDataSetDataType* configuration object that contains the metadata information for *'Simple' DataSet*. - -#### PublishedDataSet 'AllTypes' - NamespaceIndex = 3 - -| Name | DataType | ValueRank |Behavior | -|--|--|--|--| -|BoolToggle |Boolean |Scalar |Toggles every second| -|Byte|Byte|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|Int16|Int16|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|Int32|Int32|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|SByte|SByte|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|UInt16|UInt16|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|UInt32|UInt32|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|UInt64|UInt64|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|Float|Float|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|Double|Double|Scalar |Counts (1 per second) from 0 to type-max and then resets| -|String|String|Scalar |Spells the aviation alphabet (Alpha, Bravo …) (1 per second)| -|ByteString|ByteString|Scalar |1 new random ByteString per second| -|Guid|Guid|Scalar |1 new random Guid per second| -|DateTime|DateTime|Scalar |Current time refreshed with every packet sent| -|UInt32Array|UInt32|OneDimension|Counts (1 per second on every element) from 0 to type-max and then resets.

Start PubSub application - - ```csharp - // Start the publisher - uaPubSubApplication.Start(); - ``` - -After this step the *Subscriber* will listen for *NetworkMessages* as configured. - -### Subscriber Configuration - -The Subscriber configuration is a subset of the [PubSub Configuration](../../Docs/PubSub.md#pubsub-configuration). A functional *Subscriber* application needs to have a configuration (*PubSubConfigurationDataType* instance) that contains at least one connection (*PubSubConnectionDataType* instance) with at least one reader group configuration (*ReaderGroupDataType* instance). The reader group contains at least one data set reader (*DataSetReaderDataType* instance) that describes a published data set that can be processed and retrieved by the *Subscriber* application. -The diagram shows the subset of classes involved in an *OPC UA Publisher* configuration. - -![SubscriberConfigClasses](../../Docs/Images/SubscriberConfigClasses.png) +# OPC UA Console Reference Subscriber + +A self-contained .NET 10 console application that subscribes to an OPC +UA Part 14 PubSub DataSet over UDP/UADP or MQTT (UADP or JSON) using +the fluent + DI hosting surface introduced in v2.0 of the .NET +Standard stack.

Phase 18 LOW-impact polish remains backlogged but is out of scope for this commit. Documentation: - Docs/PubSub.md replaced end-to-end (~768 LOC, was 254 on master) with v1.05.06 architecture overview, fluent builder walkthrough, DI hosting, transports, encodings, security, server-side integration, AOT, spec coverage table, cross-links. - Docs/migrate/2.0.x/pubsub.md expanded from stub to full migration sub-doc (~404 LOC) covering shim/Obsolete, AMQP removal, JSON encoder swap (Newtonsoft to System.Text.Json), JsonEncodingMode rename, UADP RawData padding, DataSetFieldContentMask, DataSetReader filters, Datagram-v2, chunking, KeepAlive, security wiring, MetaDataPublisher, server-side, mutation methods, diagnostics, DI, AOT, JSON modes, compatibility matrix. - Docs/migrate/2.0.x/README.md adds pubsub row + bullet to migration index. - Docs/MigrationGuide.md cross-link added (now 13 thematic sub-docs). - Docs/WhatsNewIn2.0.md adds Part 14 PubSub modernization section (AOT, DI, fluent, v1.05.06, diagnostics, security, mutation, retained metadata). - Docs/DependencyInjection.md reverts 'PubSub is not part of DI' note (line 22); adds AddPubSub, AddPubSubPublisher, AddPubSubSubscriber, AddPubSubSecurityKeyServiceClient/Server, AddUdpTransport, AddMqttTransport, AddPubSubAddressSpace rows to quick-reference table. - Docs/Profiles.md PubSub-transports section adds Datagram-v2 (DatagramConnectionTransport2DataType), SKS pull/push, AES-128-CTR/AES-256-CTR security facets; cites Part 7 section 4.3. - Docs/NativeAoT.md adds PubSubAotTests entry to project structure + dedicated Part 14 PubSub subsection. - Docs/README.md PubSub bullets repointed at PubSub.md, migrate/2.0.x/pubsub.md, DependencyInjection.md, Profiles.md PubSub facets. Benchmarks: - Tests/Opc.Ua.PubSub.Bench replaces ScaffoldingBenchmark with UadpEncodingBenchmarks, JsonEncodingBenchmarks, SchedulerBenchmarks, SecurityBenchmarks, plus shared BenchmarkContext.cs. - Tests/Opc.Ua.PubSub.Bench/Baselines/baseline-net10-dry.md commits smoke-pass summary tables for all four suites (29 benchmarks). - Tests/Opc.Ua.PubSub.Bench/README.md documents short/medium/long runs and the --inProcess requirement (BDN autogen disables source generators so InProcessEmitToolchain is required to keep Opc.Ua.Core source-generated NodeIds compiling). Coverage gate (acceptance criterion 5): - Opc.Ua.PubSub: 37.09 percent (1007 tests across 4 suites all pass; deficit concentrated in JSON discovery/Action paths, MetaDataPublisher edges, IPubSubConfigurationStore faults, SKS server pull endpoint). DOES NOT meet 80 percent gate. - Opc.Ua.PubSub.Udp: 62.84 percent. Deficit concentrated in multicast/broadcast send, DiscoveryAnnounceRate driver, QosCategory to DSCP fallback. - Opc.Ua.PubSub.Mqtt: 60.35 percent. - Opc.Ua.PubSub.Server: 52.16 percent. Deficit concentrated in Get/SetSecurityKeys, AddSecurityGroup, per-component diagnostic Variables. All four below 80 percent gate. Per Phase 12 instructions ('only add real tests; do NOT mass-disable analyzers or use ExcludeFromCodeCoverage'), the gap is documented honestly in Docs/PubSub.md 'Test coverage' section rather than padded with shallow tests. Closing the gap is bulk-mechanical fluent-builder smoke testing and is deferred to backlog Phase 18 polish.

Instead senders, called Publishers, categorize messages into classes without knowing which receivers, if any, there may be. Similarly receivers, called Subscribers, express interest in one or more classes and only receive messages that are of interest, without knowing which senders, if any, there are. - -In February 2018 the OPC Foundation published [Part 14 of the OPC UA Specification](https://reference.opcfoundation.org/v104/Core/docs/Part14/), version 1.04, specifying the OPC UA PubSub communication model. The OPC UA PubSub communication model defines an OPC UA Publish/Subscribe pattern instead of the client/server pattern defined by the services in [Part 4 of the OPC UA Specification](https://reference.opcfoundation.org/v104/Core/docs/Part4/). - -OPC UA PubSub is designed to be flexible and is not bound to a particular messaging system. - -## Decoupling by use of middleware - -In OPC UA PubSub the participating OPC UA applications can assume the roles of Publishers and Subscribers. Publishers are the sources of data, while Subscribers consume that data. Communication in OPC UA PubSub is message-based. Publishers send messages to a Message-Oriented Middleware, without knowledge of what, if any, Subscribers there may be. Similarly, Subscribers express interest in specific types of data, and process messages that contain this data, without knowledge of what Publishers there are. - -Message-Oriented Middleware is a software or hardware infrastructure that supports sending and receiving messages between distributed systems. The implementation of the message distribution depends on the Message-Oriented Middleware. - -The image bellow illustrates that for communication Publishers and Subscribers only interact with the Message-Oriented Middleware which provides the means to receive data from one or more senders and forward data to one or more receivers: -PubSub Overview - -![Decoupling by use of middleware](Images/MessageOrientedMiddleware.png) - -To cover a large number of use cases, OPC UA PubSub supports two largely different Message-Oriented Middleware variants. These are: - -- A broker-less Message-Oriented Middleware is a network infrastructure that is able to route datagram-based messages. Subscribers and Publishers use datagram protocols like UDP. - -- A broker-based Message-Oriented Middleware is a network infrastructure that uses a message Broker as core component. Subscribers and Publishers use standard messaging protocols like AMQP or MQTT to communicate with the Broker. All messages are published to specific queues (e.g. topics, nodes) that the Broker exposes and Subscribers can listen to these queues. The Broker may translate messages from the formal messaging protocol of the Publisher to the formal messaging protocol of the Subscriber. - -## Synergy of Models - -OPC UA PubSub and OPC UA Client/Server are both based on the OPC UA Information Model but there is no necessity for Publishers or Subscribers to be either an OPC UA Server or an OPC UA Client to participate in OPC UA PubSub communications. - -The PubSub implementation is part of OPC UA .NET Standard Stack from OPC Foundation. It is totally decoupled from the Client/Server implementation but any Publisher or Subscriber component can easily be integrated into OPC UA Servers and OPC UA Clients. - -Quite typically, a Publisher will be an OPC UA Server (the owner of information) and a Subscriber is often an OPC UA Client, but it is also possible that OPC UA Clients can be Publishers and OPC UA Servers can be Subscribers. - -The **OPC UA .NET Standard PubSub Library** supports both: UDP and MQTT. - -**Note:** *Even though the PubSub functionality has been tested against the popular MQTT broker MOSQUITTO running both: as a custom setup, and as the online available instance, it should be compatible with any MQTT broker that supports the MQTT versions V310, V311 and V500 that exposes anonymous or user and password authentication with or without TLS encryption based on CA or client certificates issued by a CA.* - -*The MQTT implementation from PubSub Library was successfully tested also against the MQTT broker running on the Azure IOT Hub platform.* - -## PubSub Concepts - -The following image provides an overview of the Publisher and Subscriber entities.

It is an enumeration and the possible values are described in the following table: - -| Value |Description | -|-----|-----| -| Disabled(0) |The PubSub component is configured but currently disabled. | -| Paused(1) |The PubSub component is enabled but currently paused by a parent component. The parent component is either Disabled or Paused. | -| Operational(2)|The PubSub component is operational. | -| Error(3) |PubSub component is in an error state. | - -The image below shows the PubSub components that have a PubSub state and their parent-child relationship. State changes of children are based on changes of the parent state. The root of the hierarchy is the PublishSubscribe component and, if part an on OPC UA server it is located under Server node and has the well known NodeId = ObjectIds.PublishSubscribe. - -![PubSubStateObjects](Images/PubSubStateObjects.png) - -The Configuration API from [UaPubSubConfigurator class](#uapubsubconfigurator-class) is responsible for changing PubSub components states using the Enable() and Disable() methods.

charset=UTF-8 Content-Transfer-Encoding: 8bit Added targeted tests across all 4 PubSub libraries to lift coverage: - PubSubApplicationFullMutationTests (39 tests): AddConnection/WriterGroup/ ReaderGroup/DataSetWriter/Reader/PublishedDataSet, RemoveXxx, Replace Configuration, GetConfiguration, validation paths - PubSubMethodHandlersFullCoverageTests (71 tests): all server-side standard methods (AddConnection, RemoveConnection, SetConfiguration, GetConfiguration, AddDataSetFolder, AddPublishedDataItems, RemovePublishedDataSet, Add/Remove WriterGroup/ReaderGroup/DataSetWriter/Reader, GetSecurityGroup, AddSecurity Group) with success/duplicate/bad-config/not-found paths - AggregatingPubSubDiagnosticsTests (5 tests): per-component aggregation - MqttBrokerTransportEdgeTests (15 tests): edge cases (null endpoint, invalid broker, disconnect mid-publish, retained metadata) - UdpDatagramTransportEdgeTests (15 tests): edge cases (invalid multicast, broadcast, interface resolution, repeat-count validation) - DI builder edge tests (+18): null-config, duplicate-transport, invalid- endpoint, missing-factory paths Fixed NoWarn in Legacy.csproj to suppress UA0023/CS0618/CS0612 (allows legacy tests to exercise [Obsolete] shim). Test totals: - PubSub: 826 (+92 from 734) - Udp: 119 (+15 from 104) - Mqtt: 119 (+19 from 100) - Server: 140 (+71 from 69) - Legacy: 9316 (unchanged) - **Total: 10 520 passing** (+163) Coverage after merge (5 projects, net10 only): - Opc.Ua.PubSub: 71.8% (vs 70.1% baseline, target 80%) - Opc.Ua.PubSub.Udp: 73.8% (vs 64.2% baseline, target 80%) - Opc.Ua.PubSub.Mqtt: 71.7% (vs 62.6% baseline, target 80%) - Opc.Ua.PubSub.Server: 79.3% (vs 52.1% baseline, target 80%) All 4 libs improved but still short of 80% gate. Remaining uncovered: - Legacy shim types (UaPubSubConnection, MqttPubSubConnection, UdpPubSubConnection, PubSubConnection — 0% coverage, covered only by legacy tests) - Discovery subscriber (UdpDiscoverySubscriber 0%, defensive catch blocks) - Some polyfill/edge-case branches (HmacSha256 net48 polyfill, deadband filter edge cases, scheduler timeout branches) Plan acceptance criteria §10.5 remains PARTIAL (72% aggregate vs 80% bar). Next iteration required to close final gaps or escalate for user decision on coverage bar relaxation for legacy-shim code. Spec compliance: 0 HIGH + 0 MEDIUM gaps (unchanged). Multi-TFM build: 0/0 (unchanged). --- .../MqttBrokerTransportEdgeTests.cs | 383 +++++ .../PubSubMethodHandlersFullCoverageTests.cs | 1379 +++++++++++++++++ .../Opc.Ua.PubSub.Tests.csproj | 5 + .../PubSubApplicationFullMutationTests.cs | 761 +++++++++ .../MqttTransportBuilderExtensionsTests.cs | 109 +- .../UdpTransportBuilderExtensionsTests.cs | 127 +- .../AggregatingPubSubDiagnosticsTests.cs | 201 +++ .../Transports/PubSubTransportAddressTests.cs | 324 ++++ .../UdpDatagramTransportEdgeTests.cs | 445 ++++++ 9 files changed, 3719 insertions(+), 15 deletions(-) create mode 100644 Tests/Opc.Ua.PubSub.Mqtt.Tests/MqttBrokerTransportEdgeTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Server.Tests/PubSubMethodHandlersFullCoverageTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Application/PubSubApplicationFullMutationTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Diagnostics/AggregatingPubSubDiagnosticsTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/Transports/PubSubTransportAddressTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Udp.Tests/UdpDatagramTransportEdgeTests.cs diff --git a/Tests/Opc.Ua.PubSub.Mqtt.Tests/MqttBrokerTransportEdgeTests.cs b/Tests/Opc.Ua.PubSub.Mqtt.Tests/MqttBrokerTransportEdgeTests.cs new file mode 100644 index 0000000000..0044664412 --- /dev/null +++ b/Tests/Opc.Ua.PubSub.Mqtt.Tests/MqttBrokerTransportEdgeTests.cs @@ -0,0 +1,383 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

Changed to FromUInt16(0) so Null.IsNull == true. Discovered via coverage testing. Tests: PubSub 1150, Udp 136, Mqtt 131, Server 141, Legacy 9358 = 10,916 passing. Multi-TFM build 0/0.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase S1 (CRITICAL — SA-DEFAULT-01/02, SA-MSGSEC-01): message security was implemented + unit-tested but orphaned from the runtime data path (no IPubSubSecurityWrapperResolver implementation; publisher emitted plaintext for SignAndEncrypt groups; subscriber accepted forged cleartext). - NEW PubSubSecurityWrapperResolver (sealed, DI-injectable + directly constructable): resolves policy/keyProvider/nonceProvider/SecurityTokenWindow into a UadpSecurityWrapper for secured groups; null for SecurityMode=None. - Wired via DI (OpcUaPubSubBuilderExtensions) + PubSubApplicationBuilder + PubSubApplication ctor (optional-null retained for direct-construct fallback). - Publish FAIL-CLOSED (PSC1401): secured group with no resolvable wrapper throws at build/start instead of sending plaintext. - Receive enforcement: secured reader drops frames whose SecurityEnabled is clear or whose verified level is below configured SecurityMode, before dispatch (closes the wire-flag-trust downgrade). Fail-soft chunk reassembly. - Samples wired to SignAndEncrypt via shared StaticSecurityKeyProvider (SampleSecurity.cs); AOT publish 0 IL2026/IL3050. Phase S3 (HIGH — SA-DOS-01/02/03/04): UADP reassembler/binary reader hardened against pre-auth hostile input. - Bound wire TotalSize by MaxReassembledMessageSize (8 MiB default); reject oversized + negative-cast-range (>=0x80000000) sizes without alloc/throw. - Cap MaxConcurrentReassemblies (1024) and MaxAggregatePendingBytes (64 MiB); reject/evict instead of unbounded growth (TTL sweep retained). - EnsureRemaining before allocating padded String/ByteString outer arrays. - All limits DI-injectable + directly constructable with backward-compatible defaults. Verification: Opc.Ua.PubSub builds net10 + net48 0/0; all 4 PubSub libs net10 0/0; both samples net10 0/0; Opc.Ua.PubSub.Tests net10 1217/1217 pass (incl. 32 new S1+S3 regression tests).

Nonce-reuse now compares the FULL nonce (dropped 8-byte truncation), checked before state mutation. - UadpSecurityWrapper: unwrap now extracts the authenticated SequenceNumber from the nonce and drives TryAccept with it (was passing the constant TokenId, so the Part 14 7.2.2 replay check never ran). - AesCtrNonceLayout / RandomNonceProvider / INonceProvider: MessageNonce suffix is now the monotonic per-key MessageSequenceNumber (was a fixed PublisherId projection), with KeyNonce folded in for domain separation. 96 bits now vary (64 deterministically unique) vs 32 before -> no birthday keystream reuse. Added an injectable send-side messages-per-key cap (default 1<<48) that errors before nonce repetition. Wire format stays 12 bytes (nonce carried in the security header) so publisher/subscriber interop is preserved. Phase S2b (HIGH — SA-SKS-01): - SksSecurityGroup: added AuthorizedCallerIdentities + WithAuthorizedCaller + IsCallerAuthorized; default empty = deny all (fail-closed). - InMemoryPubSubKeyServiceServer.GetSecurityKeysAsync: enforces per-group caller authorization before returning keys; unauthorized/unknown group -> BadUserAccessDenied (was: any authenticated caller could pull any group's keys).

fails closed (opt-out: allowInsecureChannel, default false). - SA-DEFAULT-03: PubSubConfigurationValidator emits a Warning for None (PSC0054) and for unset/Invalid (PSC0055, treated as None) SecurityMode, gated by SuppressInsecureSecurityModeWarnings; no longer silent. (Kept as Warning, not a hard error, to avoid breaking unset=insecure configs; security is enforced fail-closed only when a mode is actually requested - see S1.) - SA-DEFAULT-04: PSC0056 warns on plaintext mqtt:// without message-layer security. Phase S5 (Low/Info): - SA-CRYPTO-02: zeroize transient aes.Key / HMAC key copies (CryptographicOperations.ZeroMemory). - SA-SKS-03: PubSubSecurityKey is IDisposable and zeroizes signing/encrypting/nonce buffers; PubSubSecurityKeyRing disposes keys on eviction + dispose; PullSecurity KeyProvider disposes the ring (completes the disposal chain, CA2213). - SA-TRANSPORT-01: reject MQTT credentials over plaintext mqtt:// (opt-out flag). - SA-AUDIT-01: IPubSubSecurityEventSink (typed event: kind/outcome/token/group/ publisher/caller, no key bytes) raised on sig-failure, replay rejection, unknown token, and SKS issuance/denial; default null sink preserves logging behavior. - SA-DEP-01/02: migrated legacy PubSubJsonDecoder Newtonsoft.Json -> System.Text.Json; removed Newtonsoft.Json from PubSub product code entirely. - SA-DEP-03: retired System.Net.NetworkInformation 4.3.0 metapackage (framework reference on net48 only). - SA-DOS-05: added Fuzzing/Opc.Ua.PubSub.Fuzz target (UADP decode, chunk reassembly, JSON decode entrypoints + seeds). Verification: all 4 PubSub libs build net10 + net48 0/0; samples + fuzz project build 0/0; Opc.Ua.PubSub.Tests 1250/1250, Udp 140, Mqtt 133, Server 141; legacy suite 8396 pass (verified during migration).

New IPubSubBuilder + AddPubSub(this IOpcUaBuilder, Action); ConfigureApplication(Action) replaces the sample's manual IPubSubApplication factory ('a user would not know this'). AddUdpTransport/ AddMqttTransport moved onto IPubSubBuilder (old IOpcUaBuilder overloads kept as [Obsolete] forwarders). New PubSubConfigurationBuilder family; sample config builders shrink (Publisher 238->171, Subscriber 221->153) and both Program.cs use AddOpcUa().AddPubSub(pubsub => ...). DI/PubSub docs updated. Samples AOT-clean. P2 (review #3433865884): extract [Obsolete] legacy shim cluster (44 files) into new Libraries/Opc.Ua.PubSub.Legacy (Legacy -> Opc.Ua.PubSub one-way; consumers add the Opc.Ua.PubSub.Legacy package, documented in the migration guide). Namespaces preserved. P3 (review #3433806611): rename Tests/Opc.Ua.PubSub.Tests.Legacy (csproj literally named Opc.Ua.PubSub.Tests.csproj, dll-name clash) -> Opc.Ua.PubSub.Legacy.Tests (folder/csproj/assembly/namespace). P4 (review #3433832821): fold Tests/Opc.Ua.PubSub.Bench into Tests/Opc.Ua.PubSub.Tests/Benchmarks and remove the standalone project. P5 (review #3433814802): centralize TestSpecAttribute into Tests/Opc.Ua.Test.Common; remove the two PubSub copies. Integration: UA.slnx adds Opc.Ua.PubSub.Legacy and removes Opc.Ua.PubSub.Bench; updated the Udp/Mqtt transport-DI tests to the new IPubSubBuilder pattern. Verification: all 5 PubSub libs (incl. Legacy) build net10+net48 0/0; samples AOT 0 IL warnings; PubSub 1256 / Udp 140 / Mqtt 133 / Server 141 tests pass; legacy suite 9358 pass. --- .../ConsoleReferencePublisher/Program.cs | 68 +-

Drop the now-unused Newtonsoft.Json reference and CS0612 NoWarn from Opc.Ua.PubSub.Tests. - Rewrite Docs/migrate/2.0.x/pubsub.md sections 1-2 to state the legacy API is removed (no shim/package) and update the modern NugetREADME accordingly.

[Security considerations](#8-security-considerations) + +## 1. How capture works + +The PubSub transports (`Opc.Ua.PubSub.Udp`, `Opc.Ua.PubSub.Mqtt`) expose a +zero-cost, opt-in capture seam in the `Opc.Ua.PubSub.Transports` namespace: + +- `IPubSubCaptureObserver` — receives the raw wire bytes of every sent / + received frame together with a `PubSubCaptureContext` (direction, transport + profile, endpoint / topic, timestamp). +- `IPubSubCaptureRegistry` / `PubSubCaptureRegistry` — a lock-free holder for + the active observer. The transports do a single volatile read on their hot + send / receive path; when no observer is registered there is **no** runtime + cost beyond that read. + +A diagnostics capture session installs an observer on the shared registry; the +registry is registered as a DI singleton by `AddPubSub(...)`, so the transports +and the capture tooling share the same instance. + +## 2. Capturing in-process + +`InProcessPubSubCaptureSource` implements the observer and buffers every frame +into a bounded channel. `PubSubCaptureSessionManager` owns a single active +session: + +```csharp +using Opc.Ua.PubSub.Pcap; +using Opc.Ua.PubSub.Transports; + +// The registry shared with the PubSub transports (resolve from DI in a real app). +IPubSubCaptureRegistry registry = serviceProvider + .GetRequiredService(); + +await using var manager = new PubSubCaptureSessionManager(registry); + +IPubSubCaptureSource source = await manager.StartAsync(); +// ... run the publisher / subscriber ... +await manager.StopAsync(); + +await foreach (PubSubCaptureFrame frame in source.ReadCapturedFramesAsync( + maxFrames: null, CancellationToken.None)) +{ + Console.WriteLine($"{frame.Direction} {frame.TransportProfileUri} {frame.Data.Length} bytes"); +} +``` + +## 3. Dissecting captured frames + +`PubSubOfflineDissector` projects captured bytes into structured DataSets by +reusing the standard PubSub decoders (`UadpDecoder`, `JsonDecoder`). Malformed +input is returned as an undecodable result rather than throwing. + +```csharp +var dissector = new PubSubOfflineDissector(); +await foreach (PubSubCaptureFrame frame in source.ReadCapturedFramesAsync(null, ct)) +{ + PubSubDissectionResult result = await dissector.DissectAsync(frame, ct); + // result.MessageType, result.SecurityState, result.PublisherId, + // result.WriterGroupId, result.DataSets (field name/value pairs) +} +``` + +JSON PubSub messages have no message-level security in Part 14 (confidentiality +relies on the MQTT TLS transport), so JSON frames are always dissected as +cleartext. + +## 4. Decrypting encrypted UADP messages + +Encrypted UADP NetworkMessages +([Part 14 §8.3](https://reference.opcfoundation.org/specs/OPC-10000-14/v1.05.06/8.3), +[Annex A.2.2.5 PubSub-Aes-CTR](https://reference.opcfoundation.org/specs/OPC-10000-14/v1.05.06/A.2.2.5)) +are laid out as `[outerPrefix ‖ SecurityHeader ‖ ciphertext ‖ signature]`. The +`SecurityHeader` carries the `SecurityTokenId` that selects the key. The +dissector decrypts a secured frame when a key resolves for that token id; it +reuses the production `UadpSecurityWrapper` to verify the signature and decrypt, +then dissects the recovered cleartext. Decryption failures are flagged, never +thrown. + +Keys are supplied by an `IPubSubKeyResolver`: + +- `CapturedKeyLogKeyResolver` — resolves keys from a captured key log + (`PubSubKeyLogReader`) or from the keys buffered during capture. +- `SksKeyResolver` — wraps a live `IPubSubSecurityKeyProvider` (for example a + `PullSecurityKeyProvider` backed by `OpcUaSecurityKeyServiceClient`, which + calls `PublishSubscribe.GetSecurityKeys` on the SKS server). + +```csharp +// Build a resolver from captured key material (for example a key log). +var resolver = new CapturedKeyLogKeyResolver(); +var reader = new PubSubKeyLogReader("publisher.uakeys.json"); +await foreach (PubSubKeyMaterial key in reader.ReadAllAsync(ct)) +{ + resolver.AddKeyMaterial(key); +} + +// Dissect with the resolver so encrypted UADP frames are decrypted. +// 'context' is the PubSubNetworkMessageContext used by the decoders. +var dissector = new PubSubOfflineDissector(context, resolver); + +PubSubDissectionResult result = await dissector.DissectAsync(encryptedFrame, ct); +// result.SecurityState == Encrypted, but result.DataSets now contains the +// decrypted fields. +``` + +When no key resolves, the result reports `SecurityState = Encrypted` with the +`SecurityTokenId` and the marker `"encrypted (key required)"`. + +## 5. Writing pcap / pcapng files + +`PubSubPcapWriter` writes captured UDP frames to a libpcap / pcapng file, +synthesizing Ethernet/IPv4/UDP framing so Wireshark's OPC UA PubSub dissector +can read the capture. MQTT payloads are written to the JSON / text formats +(`PubSubJsonFormatter`, `PubSubTextFormatter`) rather than synthesizing broker +TCP framing. + +```csharp +var writer = new PubSubPcapWriter(); +long written = await writer.WritePcapAsync( + source.ReadCapturedFramesAsync(null, ct), "pubsub.pcap", ct); +``` + +Real-wire capture from a network interface (SharpPcap) is also supported for UDP +multicast traffic. + +## 6.

Direct refs to Opc.Ua.PubSub(+Udp+Mqtt) added; registered in Program.cs. Mirrors the ConsoleReferencePublisher/Subscriber configuration builders. S9 (coverage) - diagnostics library line coverage raised to 83.55% (>=80% acceptance criterion): - PubSubOfflineDissectorTests (cleartext UADP/JSON, malformed input, secured UADP with/without key resolver -> decrypted vs 'key required'). - KeyResolverAndKeyLogTests (CapturedKeyLogKeyResolver/SksKeyResolver resolve hit/miss; PubSubKeyLog round-trip base64/hex). - FormatterPcapAndDependencyInjectionTests (json/text/pcap writers; AddPubSubPcap + env auto-start hosted service). - 36/36 diagnostics tests pass; MCP builds net10 0/0. --- Applications/McpServer/Opc.Ua.Mcp.csproj | 4 +- Applications/McpServer/Program.cs | 3 +- .../McpServer/PubSubRuntimeManager.cs | 929 ++++++++++++++++++ .../McpServer/Tools/PubSubRuntimeTools.cs | 135 +++ .../Dissection/KeyResolverAndKeyLogTests.cs | 298 ++++++ .../Dissection/PubSubOfflineDissectorTests.cs | 368 +++++++ ...ormatterPcapAndDependencyInjectionTests.cs | 336 +++++++ 7 files changed, 2071 insertions(+), 2 deletions(-) create mode 100644 Applications/McpServer/PubSubRuntimeManager.cs create mode 100644 Applications/McpServer/Tools/PubSubRuntimeTools.cs create mode 100644 Tests/Opc.Ua.PubSub.Diagnostics.Tests/Dissection/KeyResolverAndKeyLogTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Diagnostics.Tests/Dissection/PubSubOfflineDissectorTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Diagnostics.Tests/Formats/FormatterPcapAndDependencyInjectionTests.cs diff --git a/Applications/McpServer/Opc.Ua.Mcp.csproj b/Applications/McpServer/Opc.Ua.Mcp.csproj index bc7db3b4ab..81c8ed0066 100644 --- a/Applications/McpServer/Opc.Ua.Mcp.csproj +++ b/Applications/McpServer/Opc.Ua.Mcp.csproj @@ -36,7 +36,10 @@ + + + @@ -46,4 +49,3 @@ - diff --git a/Applications/McpServer/Program.cs b/Applications/McpServer/Program.cs index caa9c13a9e..8d508286ba 100644 --- a/Applications/McpServer/Program.cs +++ b/Applications/McpServer/Program.cs @@ -135,6 +135,7 @@ static void ConfigureServices(IServiceCollection services, PcapOptions pcapOptio { services.AddOpcUa().AddClient(options => { }); services.AddSingleton(); + services.AddSingleton(); services.AddSingleton(_ => CreateMcpServerOptions()); services.AddPcap(options => { @@ -199,6 +200,7 @@ static void ConfigureMcpTools(IMcpServerBuilder mcpServerBuilder, bool diagnosti .WithTools() .WithTools() .WithTools() + .WithTools() .WithTools() .WithTools(); @@ -239,4 +241,3 @@ static void ConfigureLogging(ILoggingBuilder logging) }); } - diff --git a/Applications/McpServer/PubSubRuntimeManager.cs b/Applications/McpServer/PubSubRuntimeManager.cs new file mode 100644 index 0000000000..3fbe841d3f --- /dev/null +++ b/Applications/McpServer/PubSubRuntimeManager.cs @@ -0,0 +1,929 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

Removed the 3 redundant direct refs. #3 (architecture): replace the in-transport capture taps with a DI-injected capturing decorator so the UDP/MQTT transports carry NO capture code (mirrors the UA-SC CapturingMessageSocket): - New CapturingPubSubTransport (wraps IPubSubTransport, taps send/receive to the observer, delegates the rest) + CapturingPubSubTransportFactory. - AddPubSubPcap() decorates every registered IPubSubTransportFactory; capture is injected only when DI-configured (call after AddUdpTransport/AddMqttTransport). - Reverted the S1 taps from UdpDatagramTransport/MqttBrokerTransport, their factories, and core AddPubSub; moved the capture seam types (IPubSubCaptureObserver/Registry, PubSubCaptureContext/Direction) into the Diagnostics lib (namespace Opc.Ua.PubSub.Pcap). Moved the seam test + added a decorator test. McpServer PubSubRuntimeManager updated to the reverted factory. #1, #2 (docs): merged Docs/PubSubDiagnostics.md into Docs/Diagnostics.md as section 5 (with the decorator architecture); the in-doc MCP-tools section now links to McpServer.md, which gained a PubSub tool catalogue. Deleted the standalone file; updated README link + UA.slnx. Builds: diagnostics lib net8/9/10 0/0, MCP net10 0/0, core PubSub net48 0/0. Tests: diagnostics 48 (incl. decorator), PubSub 1058, no regressions. --- Applications/McpServer/Opc.Ua.Mcp.csproj | 3 - .../McpServer/PubSubRuntimeManager.cs | 5 +- Docs/Diagnostics.md | 108 +++++++- Docs/McpServer.md | 44 ++++ Docs/PubSubDiagnostics.md | 195 --------------- Docs/README.md | 2 +- .../Capture/CapturingPubSubTransport.cs | 176 +++++++++++++ .../CapturingPubSubTransportFactory.cs | 83 +++++++ .../Capture/IPubSubCaptureObserver.cs | 2 +- .../Capture/IPubSubCaptureRegistry.cs | 2 +- .../Capture/InProcessPubSubCaptureSource.cs | 1 - .../Capture/PubSubCaptureContext.cs | 2 +- .../Capture/PubSubCaptureDirection.cs | 2 +- .../Capture/PubSubCaptureFrame.cs | 1 - .../Capture/PubSubCaptureRegistry.cs | 2 +- .../Capture/PubSubCaptureSessionManager.cs | 1 - ...ubPcapEnvironmentAutoStartHostedService.cs | 1 - .../PubSubPcapServiceCollectionExtensions.cs | 59 ++++- .../Dissection/PubSubDissectionResult.cs | 1 - .../Formats/PubSubPcapWriter.cs | 1 - ...qttTransportServiceCollectionExtensions.cs | 6 +- .../Opc.Ua.PubSub.Mqtt/MqttBrokerTransport.cs | 38 +-- .../MqttPubSubTransportFactory.cs | 13 +- .../Opc.Ua.PubSub.Udp/UdpDatagramTransport.cs | 40 +-- .../UdpPubSubTransportFactory.cs | 14 +- .../OpcUaPubSubBuilderExtensions.cs | 1 - .../Capture/CapturingPubSubTransportTests.cs | 231 ++++++++++++++++++ .../Capture}/PubSubCaptureRegistryTests.cs | 3 +- UA.slnx | 1 - 29 files changed, 710 insertions(+), 328 deletions(-) delete mode 100644 Docs/PubSubDiagnostics.md create mode 100644 Libraries/Opc.Ua.PubSub.Diagnostics/Capture/CapturingPubSubTransport.cs create mode 100644 Libraries/Opc.Ua.PubSub.Diagnostics/Capture/CapturingPubSubTransportFactory.cs rename Libraries/{Opc.Ua.PubSub/Transports => Opc.Ua.PubSub.Diagnostics}/Capture/IPubSubCaptureObserver.cs (99%) rename Libraries/{Opc.Ua.PubSub/Transports => Opc.Ua.PubSub.Diagnostics}/Capture/IPubSubCaptureRegistry.cs (98%) rename Libraries/{Opc.Ua.PubSub/Transports => Opc.Ua.PubSub.Diagnostics}/Capture/PubSubCaptureContext.cs (99%) rename Libraries/{Opc.Ua.PubSub/Transports => Opc.Ua.PubSub.Diagnostics}/Capture/PubSubCaptureDirection.cs (98%) rename Libraries/{Opc.Ua.PubSub/Transports => Opc.Ua.PubSub.Diagnostics}/Capture/PubSubCaptureRegistry.cs (98%) create mode 100644 Tests/Opc.Ua.PubSub.Diagnostics.Tests/Capture/CapturingPubSubTransportTests.cs rename Tests/{Opc.Ua.PubSub.Tests/Transports => Opc.Ua.PubSub.Diagnostics.Tests/Capture}/PubSubCaptureRegistryTests.cs (98%) diff --git a/Applications/McpServer/Opc.Ua.Mcp.csproj b/Applications/McpServer/Opc.Ua.Mcp.csproj index 81c8ed0066..7d8ede6136 100644 --- a/Applications/McpServer/Opc.Ua.Mcp.csproj +++ b/Applications/McpServer/Opc.Ua.Mcp.csproj @@ -36,10 +36,7 @@ - - - diff --git a/Applications/McpServer/PubSubRuntimeManager.cs b/Applications/McpServer/PubSubRuntimeManager.cs index 3fbe841d3f..5ab0373335 100644 --- a/Applications/McpServer/PubSubRuntimeManager.cs +++ b/Applications/McpServer/PubSubRuntimeManager.cs @@ -278,13 +278,10 @@ private async ValueTask ReplaceAndStartAsync( private PubSubApplicationBuilder CreateBuilder(string applicationId) { var telemetry = new ServiceProviderTelemetryContext(m_services); - IPubSubCaptureRegistry? captureRegistry = m_services.GetService(); return new PubSubApplicationBuilder(telemetry) .WithApplicationId(applicationId) .AddTransportFactory(new UdpPubSubTransportFactory( - Options.Create(new UdpTransportOptions()), - diagnostics: null, - captureRegistry)) + Options.Create(new UdpTransportOptions()))) .AddEncoder(new UadpEncoder()) .AddDecoder(new UadpDecoder()); } diff --git a/Docs/Diagnostics.md b/Docs/Diagnostics.md index 527791a335..4b490faa09 100644 --- a/Docs/Diagnostics.md +++ b/Docs/Diagnostics.md @@ -12,7 +12,8 @@ It replaces the previous `Observability.md` and `PacketCapture.md` docs. - [2.

[Security considerations](#8-security-considerations) - -## 1. How capture works - -The PubSub transports (`Opc.Ua.PubSub.Udp`, `Opc.Ua.PubSub.Mqtt`) expose a -zero-cost, opt-in capture seam in the `Opc.Ua.PubSub.Transports` namespace: - -- `IPubSubCaptureObserver` — receives the raw wire bytes of every sent / - received frame together with a `PubSubCaptureContext` (direction, transport - profile, endpoint / topic, timestamp). -- `IPubSubCaptureRegistry` / `PubSubCaptureRegistry` — a lock-free holder for - the active observer. The transports do a single volatile read on their hot - send / receive path; when no observer is registered there is **no** runtime - cost beyond that read. - -A diagnostics capture session installs an observer on the shared registry; the -registry is registered as a DI singleton by `AddPubSub(...)`, so the transports -and the capture tooling share the same instance. - -## 2. Capturing in-process - -`InProcessPubSubCaptureSource` implements the observer and buffers every frame -into a bounded channel. `PubSubCaptureSessionManager` owns a single active -session: - -```csharp -using Opc.Ua.PubSub.Pcap; -using Opc.Ua.PubSub.Transports; - -// The registry shared with the PubSub transports (resolve from DI in a real app). -IPubSubCaptureRegistry registry = serviceProvider - .GetRequiredService(); - -await using var manager = new PubSubCaptureSessionManager(registry); - -IPubSubCaptureSource source = await manager.StartAsync(); -// ... run the publisher / subscriber ... -await manager.StopAsync(); - -await foreach (PubSubCaptureFrame frame in source.ReadCapturedFramesAsync( - maxFrames: null, CancellationToken.None)) -{ - Console.WriteLine($"{frame.Direction} {frame.TransportProfileUri} {frame.Data.Length} bytes"); -} -``` - -## 3. Dissecting captured frames - -`PubSubOfflineDissector` projects captured bytes into structured DataSets by -reusing the standard PubSub decoders (`UadpDecoder`, `JsonDecoder`). Malformed -input is returned as an undecodable result rather than throwing. - -```csharp -var dissector = new PubSubOfflineDissector(); -await foreach (PubSubCaptureFrame frame in source.ReadCapturedFramesAsync(null, ct)) -{ - PubSubDissectionResult result = await dissector.DissectAsync(frame, ct); - // result.MessageType, result.SecurityState, result.PublisherId, - // result.WriterGroupId, result.DataSets (field name/value pairs) -} -``` - -JSON PubSub messages have no message-level security in Part 14 (confidentiality -relies on the MQTT TLS transport), so JSON frames are always dissected as -cleartext. - -## 4. Decrypting encrypted UADP messages - -Encrypted UADP NetworkMessages -([Part 14 §8.3](https://reference.opcfoundation.org/specs/OPC-10000-14/v1.05.06/8.3), -[Annex A.2.2.5 PubSub-Aes-CTR](https://reference.opcfoundation.org/specs/OPC-10000-14/v1.05.06/A.2.2.5)) -are laid out as `[outerPrefix ‖ SecurityHeader ‖ ciphertext ‖ signature]`. The -`SecurityHeader` carries the `SecurityTokenId` that selects the key. The -dissector decrypts a secured frame when a key resolves for that token id; it -reuses the production `UadpSecurityWrapper` to verify the signature and decrypt, -then dissects the recovered cleartext. Decryption failures are flagged, never -thrown. - -Keys are supplied by an `IPubSubKeyResolver`: - -- `CapturedKeyLogKeyResolver` — resolves keys from a captured key log - (`PubSubKeyLogReader`) or from the keys buffered during capture. -- `SksKeyResolver` — wraps a live `IPubSubSecurityKeyProvider` (for example a - `PullSecurityKeyProvider` backed by `OpcUaSecurityKeyServiceClient`, which - calls `PublishSubscribe.GetSecurityKeys` on the SKS server). - -```csharp -// Build a resolver from captured key material (for example a key log). -var resolver = new CapturedKeyLogKeyResolver(); -var reader = new PubSubKeyLogReader("publisher.uakeys.json"); -await foreach (PubSubKeyMaterial key in reader.ReadAllAsync(ct)) -{ - resolver.AddKeyMaterial(key); -} - -// Dissect with the resolver so encrypted UADP frames are decrypted. -// 'context' is the PubSubNetworkMessageContext used by the decoders. -var dissector = new PubSubOfflineDissector(context, resolver); - -PubSubDissectionResult result = await dissector.DissectAsync(encryptedFrame, ct); -// result.SecurityState == Encrypted, but result.DataSets now contains the -// decrypted fields. -``` - -When no key resolves, the result reports `SecurityState = Encrypted` with the -`SecurityTokenId` and the marker `"encrypted (key required)"`. - -## 5. Writing pcap / pcapng files - -`PubSubPcapWriter` writes captured UDP frames to a libpcap / pcapng file, -synthesizing Ethernet/IPv4/UDP framing so Wireshark's OPC UA PubSub dissector -can read the capture. MQTT payloads are written to the JSON / text formats -(`PubSubJsonFormatter`, `PubSubTextFormatter`) rather than synthesizing broker -TCP framing. - -```csharp -var writer = new PubSubPcapWriter(); -long written = await writer.WritePcapAsync( - source.ReadCapturedFramesAsync(null, ct), "pubsub.pcap", ct); -``` - -Real-wire capture from a network interface (SharpPcap) is also supported for UDP -multicast traffic. - -## 6. Environment-variable auto-capture - -`AddPubSubPcapFromEnvironment()` auto-starts an in-process capture when an -environment variable is set, and flushes it to disk on host shutdown: - -| Variable | Effect | -| --- | --- | -| `OPCUA_PUBSUB_PCAP_FILE` | Auto-start capture; write to this `.pcap` / `.pcapng` on stop. | -| `OPCUA_PUBSUB_KEYLOGFILE` | Path for the captured PubSub key log (for offline decryption). | - -```csharp -builder.Services - .AddOpcUa() - .AddPubSub(pubsub => pubsub.AddPublisher().AddUdpTransport()); -builder.Services.AddPubSubPcapFromEnvironment(); -``` - -## 7.

Security considerations - -- The key log and any captured key material contain **live security keys**. - `PubSubKeyMaterial` defensively copies and zeroizes key bytes on dispose, but - the key-log file is plaintext JSON-lines — protect it like a private key and - delete it when no longer needed. -- Capture is opt-in and inert until an observer is registered; never enable it - in production without controlling access to the output files. -- Decryption is an offline diagnostic aid; it reuses the production security - primitives unchanged and does not weaken the runtime security path. diff --git a/Docs/README.md b/Docs/README.md index b1aff15a03..bf8970676e 100644 --- a/Docs/README.md +++ b/Docs/README.md @@ -38,7 +38,7 @@ Here is a list of available documentation for different topics: * [Migration sub-doc](migrate/2.0.x/pubsub.md) - 1.5.378 → 2.0 breaking API, transport, JSON, and field-encoding changes, plus the compatibility matrix. * [Dependency Injection extensions](DependencyInjection.md) - `AddPubSub`, `AddPubSubPublisher`, `AddPubSubSubscriber`, `AddPubSubSecurityKeyServiceClient/Server`, `AddPubSubAddressSpace`. * [Profiles](Profiles.md#pubsub-transports) - Datagram-v2, SKS pull / push, AES-128/256-CTR security facets. - * [PubSub Diagnostics](PubSubDiagnostics.md) - packet capture, dissection and replay of UDP / MQTT PubSub traffic, including decryption of encrypted UADP messages. + * [PubSub Diagnostics](Diagnostics.md#5-pubsub-packet-capture-and-dissection) - packet capture, dissection and replay of UDP / MQTT PubSub traffic, including decryption of encrypted UADP messages. ## Reference application related diff --git a/Libraries/Opc.Ua.PubSub.Diagnostics/Capture/CapturingPubSubTransport.cs b/Libraries/Opc.Ua.PubSub.Diagnostics/Capture/CapturingPubSubTransport.cs new file mode 100644 index 0000000000..96b8872734 --- /dev/null +++ b/Libraries/Opc.Ua.PubSub.Diagnostics/Capture/CapturingPubSubTransport.cs @@ -0,0 +1,176 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

E1 - removed the redundant PubSubActionTools + PubSubKeyServiceTools (thin Session.Call wrappers); PubSub configuration + SKS methods are now invoked via the generic 'Call' tool. Updated McpServer.md accordingly. E2 - PubSub discovery (Part 14 §7.2.4.6), built on the existing discovery coders: - Library: IPubSubApplication.RequestDiscoveryAsync(PubSubDiscoveryRequest, timeout) collects DataSetMetaData / DataSetWriterConfiguration / PublisherEndpoints responses into a typed PubSubDiscoveryResult; the connection receive loop routes discovery responses to the in-flight request, and publisher connections answer inbound discovery requests for all three types. - MCP: PubSubDiscoveryTools (pubsub_discover_metadata / _writer_config / _publisher_endpoints) via PubSubRuntimeManager.RequestDiscoveryAsync. - Docs: McpServer.md discovery tools + PubSub.md client discovery API. Part 14 Actions (request/response over PubSub) are designed for a follow-up PR in plans/28-pubsub-actions.md (only type stubs exist today; no runtime).

PubSubActionMethodRegistrar + WithActionMethodHandlers(dataSetWriterId, PublishedActionMethodDataType, connectionName) auto-register handlers on the running IPubSubApplication; wired into the PubSub server builder/DI/node-manager. S6 (DI + fluent): PubSubApplicationBuilder.AddActionResponder(target, handler) + delegate overload + DI equivalents (AddActionResponder/factory), mirroring the existing deferred-DI builder pattern. Builds PubSub + PubSub.Server net10/net48 0/0; server action method-binding tests (3) + fluent/DI responder tests pass. --- .../OpcUaServerBuilderPubSubExtensions.cs | 5 +- .../PubSubServerBuilderExtensions.cs | 33 +++ .../PubSubActionMethodRegistrar.cs | 106 +++++++ .../PubSubActionMethodRegistration.cs | 72 +++++ .../Opc.Ua.PubSub.Server/PubSubNodeManager.cs | 27 +- .../PubSubNodeManagerFactory.cs | 11 +- .../ServerMethodActionHandler.cs | 209 +++++++++++++ .../Application/PubSubApplicationBuilder.cs | 52 +++- .../DependencyInjection/IPubSubBuilder.cs | 37 +++ .../OpcUaPubSubBuilderExtensions.cs | 2 +- .../DependencyInjection/PubSubBuilder.cs | 57 ++++ ...OpcUaServerBuilderPubSubExtensionsTests.cs | 42 +++ .../ServerMethodActionHandlerTests.cs | 205 +++++++++++++ .../PubSubActionResponderBuilderTests.cs | 277 ++++++++++++++++++ 14 files changed, 1129 insertions(+), 6 deletions(-) create mode 100644 Libraries/Opc.Ua.PubSub.Server/PubSubActionMethodRegistrar.cs create mode 100644 Libraries/Opc.Ua.PubSub.Server/PubSubActionMethodRegistration.cs create mode 100644 Libraries/Opc.Ua.PubSub.Server/ServerMethodActionHandler.cs create mode 100644 Tests/Opc.Ua.PubSub.Server.Tests/ServerMethodActionHandlerTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Tests/DependencyInjection/PubSubActionResponderBuilderTests.cs diff --git a/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/OpcUaServerBuilderPubSubExtensions.cs b/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/OpcUaServerBuilderPubSubExtensions.cs index fbd728b4be..87750ecf59 100644 --- a/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/OpcUaServerBuilderPubSubExtensions.cs +++ b/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/OpcUaServerBuilderPubSubExtensions.cs @@ -28,6 +28,7 @@ * ======================================================================*/ using System; +using System.Collections.Generic; using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection.Extensions; using Microsoft.Extensions.Options; @@ -206,7 +207,9 @@ private static void RegisterCommonServices(IServiceCollection services) IPubSubApplication application = sp.GetRequiredService(); IPubSubKeyServiceServer? keyService = sp.GetService(); ITelemetryContext telemetry = sp.GetRequiredService(); - return new PubSubNodeManagerFactory(application, keyService, options, telemetry); + IEnumerable registrations = + sp.GetServices(); + return new PubSubNodeManagerFactory(application, keyService, options, telemetry, registrations); }); services.AddSingleton(sp => diff --git a/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/PubSubServerBuilderExtensions.cs b/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/PubSubServerBuilderExtensions.cs index 9892e2cf53..7a9026c26b 100644 --- a/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/PubSubServerBuilderExtensions.cs +++ b/Libraries/Opc.Ua.PubSub.Server/DependencyInjection/PubSubServerBuilderExtensions.cs @@ -88,5 +88,38 @@ public static IPubSubServerBuilder WithSecurityKeyServiceServer( return builder.ExposeSecurityKeyService(); } + + /// + /// Registers server Method handlers for every target in a PublishedActionMethod. + /// + /// PubSub server builder. + /// DataSetWriterId that owns the action metadata. + /// PublishedActionMethod metadata to bind. + /// Optional PubSub connection name used for runtime routing. + /// The same builder for chaining. + /// + /// or is . + /// + public static IPubSubServerBuilder WithActionMethodHandlers( + this IPubSubServerBuilder builder, + ushort dataSetWriterId, + PublishedActionMethodDataType publishedAction, + string connectionName = "") + { + if (builder is null) + { + throw new ArgumentNullException(nameof(builder)); + } + if (publishedAction is null) + { + throw new ArgumentNullException(nameof(publishedAction)); + } + + builder.Services.AddSingleton(new PubSubActionMethodRegistration( + dataSetWriterId, + publishedAction, + connectionName)); + return builder; + } } } diff --git a/Libraries/Opc.Ua.PubSub.Server/PubSubActionMethodRegistrar.cs b/Libraries/Opc.Ua.PubSub.Server/PubSubActionMethodRegistrar.cs new file mode 100644 index 0000000000..94726a3c45 --- /dev/null +++ b/Libraries/Opc.Ua.PubSub.Server/PubSubActionMethodRegistrar.cs @@ -0,0 +1,106 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

Reassembly is now a pre-step: the reassembled message's outer prefix is re-read and routed through the same fail-closed RequiresInboundSecurity/unwrap enforcement as single-datagram frames, blocking forged-plaintext injection on Sign/SignAndEncrypt subscribers and repairing the legit secured+chunked path. SA-ACT-01: inbound Action requests were served with no authn/authz. Action serving is now fail-closed: UADP Action requests are served only on a message-secured (verified) connection, JSON Action requests only when explicitly opted in via the new AllowUnsecured flag on RegisterActionHandler/AddActionResponder (MCP runtime opts in explicitly).

Exposes HasHighest/HighestSequenceNumber on DtlsAntiReplayWindow. HS-07: bound DtlsHandshakeReassembler allocations (max message length + max concurrent in-flight messages) so an attacker-controlled 24-bit MessageLength cannot drive unbounded allocation if reassembly is wired into the live path. SA-CERT-01 (Info, latent) intentionally NOT changed: a per-instance idempotent Dispose guard is incompatible with the Certificate AddRef-returns-this refcount model (breaks legitimate per-AddRef disposal, caught by the Core RefCounting leak test); a proper fix needs an ownership-model redesign.

Network and server load scale with the publish cadence and field count. | +| `ExternalReadMode.Subscription` | The adapter creates client Subscriptions, adds monitored items for the referenced PublishedDataSet variables, maintains a latest-value cache from data-change notifications, primes that cache with one initial `Read`, and samples the cache during publish cycles. | Lower publish-path latency and server-driven updates. More lifecycle state: Subscriptions and monitored items must be created, applied, primed, and kept alive by the managed session. | + +Cyclic mode is the default and is a good fit when the publish interval is modest, field counts are small, or the external server should only be sampled at the PubSub cadence. Subscription mode is a better fit when values change independently of the publish cadence, lower latency matters, or the external server can serve monitored items more efficiently than repeated Read calls. + +### Subscription affinity + +`ExternalSubscriptionAffinity` controls how subscription-mode monitored items are grouped. + +| Affinity | Behavior | Guidance | +| -------- | -------- | -------- | +| `WriterGroup` | One client Subscription per WriterGroup. The subscription publishing interval is the WriterGroup publishing interval, or 1000 ms when the WriterGroup interval is not set. This is the default. | Prefer this for most deployments because it aligns the client/server sampling group with the Part 14 WriterGroup cadence and reduces subscription count. | +| `DataSetWriter` | One client Subscription per DataSetWriter, using the owning WriterGroup publishing interval. | Use this when writers need isolation, when a server applies per-subscription limits or diagnostics that should map to one writer, or when you want to contain noisy datasets. | + +For each affinity group, the coordinator de-duplicates monitored items by node and attribute, uses `PublishedVariableDataType.SamplingIntervalHint` when set, otherwise uses the group publishing interval, applies the monitored items server-side, and then primes the cache with a one-shot `Read`. Until a value is primed or a data change arrives, the cache returns `UncertainInitialValue` for that field. + +## Subscriber adapter + +`AddExternalServerSubscriber` registers a sink for every configured DataSetReader whose `SubscribedDataSet` is `TargetVariablesDataType`. The normal PubSub subscriber resolves incoming DataSet fields to `FieldTargetDataType` entries; the adapter writes each resolved field to the configured external node, attribute, and write index range. + +```csharp +using Microsoft.Extensions.DependencyInjection; +using Microsoft.Extensions.Hosting; +using Opc.Ua; +using Opc.Ua.PubSub.Adapter.Session; + +HostApplicationBuilder builder = Host.CreateApplicationBuilder(args); +ApplicationConfiguration clientConfiguration = await LoadClientConfigurationAsync(); + +builder.Services.AddOpcUa() + .AddPubSub(pubsub => pubsub + .AddSubscriber() + .AddMqttTransport() + .UseConfigurationFile("subscriber.xml") + .AddExternalServerSubscriber(options => + { + options.Connection.EndpointUrl = "opc.tcp://localhost:4840"; + options.Connection.SecurityMode = MessageSecurityMode.SignAndEncrypt; + options.Connection.SecurityPolicyUri = SecurityPolicies.Basic256Sha256; + options.Connection.ApplicationConfiguration = clientConfiguration; + options.Connection.SessionName = "PubSub external subscriber"; + })); + +await builder.Build().RunAsync(); +``` + +The writer is fail-soft for service and transport faults: it logs the failure and returns a Bad status for that field so the receive loop can continue. Cancellation still propagates. + +## Action responder adapter + +`AddExternalServerActionResponder` maps inbound PubSub Actions to external OPC UA Method Calls. `Targets` lists the `PubSubActionTarget` values that should be handled. `MethodMap` resolves each target to an external object and method, either by `(DataSetWriterId, ActionTargetId)` or by `ActionName`. Action input fields are converted to method input arguments in order. Method output arguments are converted back to Action response fields using the configured output field names; positions without names become `Output0`, `Output1`, and so on. + +```csharp +using Microsoft.Extensions.DependencyInjection; +using Microsoft.Extensions.Hosting; +using Opc.Ua; +using Opc.Ua.PubSub.Adapter.Actions; +using Opc.Ua.PubSub.Adapter.Session; +using Opc.Ua.PubSub.Application; + +HostApplicationBuilder builder = Host.CreateApplicationBuilder(args); +ApplicationConfiguration clientConfiguration = await LoadClientConfigurationAsync(); + +var target = new PubSubActionTarget +{ + DataSetWriterId = 1001, + ActionTargetId = 1, + ActionName = "ResetMachine" +}; + +builder.Services.AddOpcUa() + .AddPubSub(pubsub => pubsub + .AddSubscriber() + .AddMqttTransport() + .UseConfigurationFile("actions.xml") + .AddExternalServerActionResponder(options => + { + options.Connection.EndpointUrl = "opc.tcp://localhost:4840"; + options.Connection.SecurityMode = MessageSecurityMode.SignAndEncrypt; + options.Connection.SecurityPolicyUri = SecurityPolicies.Basic256Sha256; + options.Connection.ApplicationConfiguration = clientConfiguration; + options.Targets.Add(target); + options.MethodMap.Add( + dataSetWriterId: 1001, + actionTargetId: 1, + objectId: new NodeId("ns=2;s=Machine1"), + methodId: new NodeId("ns=2;s=Machine1.Reset"), + outputFieldNames: new[] { "Accepted" }.ToArrayOf()); + options.AllowUnsecured = false; + })); + +await builder.Build().RunAsync(); +``` + +Action responders honor the Part 14 security posture of the Action exchange. `AllowUnsecured` defaults to `false`; keep it false unless the deployment explicitly accepts unsecured Action requests and responses. With the default, the responder fails closed for unsecured action paths. + +## Metadata behavior + +Publisher metadata is configuration-first and server-fallback. The adapter builds the field set, order, and names from the configured `PublishedDataSetDataType`, its `PublishedDataItemsDataType.PublishedData`, and any declared `DataSetMetaDataType`. If a field does not declare type information, `ExternalDataSetMetaDataBuilder` reads `DataType`, `ValueRank`, and `ArrayDimensions` from the external server. If the fallback read fails, the field remains conservative: `BaseDataType`, `Variant`, scalar. + +This behavior keeps Part 14 metadata stable when the configuration is complete and still lets a bridge infer missing type details from the source server during startup or the first publish sample. + +## Lifecycle and resilience + +The adapter registrations add `ExternalServerAdapterRuntime` and `ExternalServerAdapterHostedService`. The runtime owns sessions and subscription coordinators. On host start, subscription-mode publisher coordinators connect the session, create the client Subscriptions, add monitored items, apply changes, and prime caches. Cyclic publishers, subscribers, and action responders connect lazily on first service call. On host shutdown, coordinators and sessions are disposed. + +`ManagedSession` handles keep-alive and reconnect for the underlying client session. Adapter read, write, and call components are fail-soft for ordinary service or transport faults: publisher fields become Bad-quality values, subscriber writes return Bad field status, and action failures return Bad action status. Cancellation and disposal still propagate normally. + +## Security notes + +The external client session uses the same stack security configuration model as other OPC UA clients. Use the certificate manager and trust stores described in [Certificates](Certificates.md) for application instance certificates, issuers, trusted peers, and rejected certificates. Prefer `MessageSecurityMode.SignAndEncrypt` with a SHA-2 security policy such as `SecurityPolicies.Basic256Sha256` or stronger policies supported by the server. + +For Actions, leave `ExternalServerActionResponderOptions.AllowUnsecured` at its default `false` unless an application-specific risk assessment requires otherwise.

Add a regression test for the exact SA-CERT-01 scenario: with two live references + (root + `AddRef()`), double-`Dispose()` of ONE must not free the shared inner cert; + the other reference stays usable; full release disposes exactly once; counters balance. +4.

Supporting code merged + renamespaced to Quickstarts.ConsoleReferencePubSub; the two identical SampleSecurity files deduped. Removed the three old app folders + their UA.slnx entries; repointed Opc.Ua.Aot.Tests to the merged sample (single pubsubsample alias); updated README/Docs references.

The builder retries resolution on each publish cycle (`ResolveAsync`) until the server read succeeds, and exposes `RefreshAsync` to force a fresh resolution on demand (for example from a model-change subscription or a scheduled refresh).

A browse path is carried as a sentinel `NodeId` whose namespace-zero string identifier starts with `/` (hierarchical) or `.` (aggregates), for example `/2:Demo/2:CurrentTime`. Use `NodeBrowsePath.ToNodeId("/2:Demo/2:CurrentTime")`, or the `ActionMethodMap.Add(actionName, objectBrowsePath, methodBrowsePath)` overload. The adapter resolves browse paths against the server with `TranslateBrowsePathsToNodeIds` the first time the node is used and caches the result, so mappings can be authored without knowing the server-assigned identifiers in advance. Each segment is parsed with `QualifiedName.Parse`, so `2:Name` selects the target namespace; named reference types are not supported in this shorthand (supply a concrete `NodeId` for those). + +### Lifecycle and resilience + +The adapter registrations add `ServerAdapterRuntime` and `ServerAdapterHostedService`.

From 2768d69bba410d9c81da514efa7b6c2b66c2346e Mon Sep 17 00:00:00 2001 From: Marc Schier Date: Wed, 24 Jun 2026 19:54:37 +0200 Subject: [PATCH 105/125] PubSub adapter hot-reload, model-change monitoring, runtime data-set providers Adds incremental hot-reload and live model-change handling to the external-server PubSub adapter, plus the core enabler that lets sources/sinks be (re)registered at runtime. Opc.Ua.PubSub (additive): - IDataSetSourceProvider / IDataSetSinkProvider + MutableDataSetSourceProvider / MutableDataSetSinkProvider; PubSubApplication consults the provider on every (re)build (build-time dictionary still wins; null-provider path unchanged). DI registers them as singletons. - IPubSubApplication.ClearActionHandlers() so action-handler registrations can be rebuilt on reconfigure (fixes stale AllowUnsecured + unbounded growth). Opc.Ua.PubSub.Adapter: - ServerAdapterReloadCoordinator reacts to IPubSubConfigurationStore.Changed and named IOptionsMonitor changes; debounced + serialized; diffs old/new config and incrementally rewires only changed publisher sources / subscriber sinks / action responders via the mutable providers, then ReplaceConfigurationAsync. DisposeAsync coordinates with the reload lock. - ServerAdapterRuntime extended with a reference-counted session pool keyed by ServerConnectionOptions (now value-equatable incl. credentials) so unchanged connections reuse sessions and unreferenced sessions are disposed. - Configuration-bound named-options overloads AddServerAsPublisher/Subscriber/ActionResponder(name, IConfiguration); existing Action overloads preserved. - f11mc: IServerSession.ModelChanged + StartModelChangeMonitoringAsync (GeneralModelChangeEvents event-monitored item on Server, coalesced, fail-soft); DataSetMetaDataBuilder refreshes + re-emits metadata on model change with trailing-edge re-arm.

The configuration source is pluggable, so a change-feed-backed configuration service such as etcd can drive live reconfiguration. Full hot reload remains a planned follow-up and extension point; it is not fully implemented yet. +Adapter hot reload is coordinated by `ServerAdapterReloadCoordinator`. After the host starts, the coordinator listens to both `IPubSubConfigurationStore.Changed` and named `IOptionsMonitor`, `IOptionsMonitor`, and `IOptionsMonitor` changes. Reloads are debounced for about 250 ms and serialized so a burst of configuration-store and options reload tokens is applied as one ordered update. + +The coordinator diffs the previous binding state against the new `PubSubConfigurationDataType` and named options, then rewires only the affected publisher sources, subscriber sinks, or action responders. Publisher and subscriber rewires update the mutable data-set provider layer (`MutableDataSetSourceProvider` / `MutableDataSetSinkProvider`) and then call `IPubSubApplication.ReplaceConfigurationAsync` so the core runtime observes the same configuration document. Adapter sessions are pooled by `ServerConnectionOptions` value equality (`EndpointUrl`, `SecurityMode`, `SecurityPolicyUri`, `UserName`, `SessionName`, `SessionTimeout`, `ApplicationName`); unchanged connections keep their managed session, while sessions with no remaining binding references are disposed. + +Use `AddServerAsPublisher(string name, IConfiguration configuration)`, `AddServerAsSubscriber(string name, IConfiguration configuration)`, or `AddServerAsActionResponder(string name, IConfiguration configuration)` when adapter options should be bound from reloadable configuration. The existing `Action` overloads still work for code-set options. Object-typed members are intentionally code-set, not `IConfiguration`-bound: `ServerConnectionOptions.ApplicationConfiguration`, `ServerConnectionOptions.UserIdentity`, `ServerActionResponderOptions.MethodMap`, and `ServerActionResponderOptions.Targets`. + +Known limitation: removing an action target requires a host restart because the core `RegisterActionHandler` API has no unregister counterpart today. Adding targets and changing action mappings are applied live. + +#### Pluggable configuration sources (change feed) + +`IPubSubConfigurationStore` is the extension point for change-feed-backed configuration. A custom store loads and saves the current `PubSubConfigurationDataType`, exposes configuration-version helpers, and raises `Changed` with `PubSubConfigurationChangedEventArgs(previous, current)` whenever an external source changes. The reload coordinator consumes that event and applies the same incremental rewire path used for named-options changes. The external source can be etcd, Consul, a Kubernetes ConfigMap watch, a database notification, or a file.

Metadata refresh has three triggers: per-cycle retry (`ResolveAsync`) until a failed server read succeeds, source-server model-change events, and explicit `RefreshAsync` calls from application code or a scheduled refresh. For model changes, the adapter session creates an EventNotifier monitored item on the Server object with an `OfType(GeneralModelChangeEventType)` filter, coalesces notifications for about 250 ms, and fails soft when the source server does not support `GeneralModelChangeEvents`. A model change calls `DataSetMetaDataBuilder.RefreshAsync`. When any (re)resolution changes the enriched metadata, the source raises `IMetaDataChangeNotifier.MetaDataChanged`; the owning `PublishedDataSet` then rebuilds and re-emits a DataSetMetaData message so subscribers observe the corrected field types without a restart. ### Browse-path node mapping diff --git a/Libraries/Opc.Ua.PubSub.Adapter/DependencyInjection/OpcUaPubSubAdapterBuilderExtensions.cs b/Libraries/Opc.Ua.PubSub.Adapter/DependencyInjection/OpcUaPubSubAdapterBuilderExtensions.cs index 05ff4fcc93..30757903b0 100644 --- a/Libraries/Opc.Ua.PubSub.Adapter/DependencyInjection/OpcUaPubSubAdapterBuilderExtensions.cs +++ b/Libraries/Opc.Ua.PubSub.Adapter/DependencyInjection/OpcUaPubSubAdapterBuilderExtensions.cs @@ -29,9 +29,12 @@ using System; using System.Collections.Generic; +using System.Globalization; +using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection.Extensions; using Microsoft.Extensions.Hosting; using Microsoft.Extensions.Logging; +using Microsoft.Extensions.Options; using Opc.Ua; using Opc.Ua.PubSub.Adapter; using Opc.Ua.PubSub.Adapter.Actions; @@ -87,82 +90,92 @@ public static class OpcUaPubSubAdapterBuilderExtensions public static IPubSubBuilder AddServerAsPublisher( this IPubSubBuilder builder, Action configure) + { + return AddServerAsPublisher( + builder, Microsoft.Extensions.Options.Options.DefaultName, configure); + } + + /// + /// Adds an external-server PubSub publisher whose options are bound from + /// configuration under the supplied name. + /// + /// + /// The PubSub builder to add the publisher to. + /// + /// + /// The named-options registration name. + /// + /// + /// The configuration section that binds the publisher options.

Extend the existing IsUdpEnvironmentFailure -> Assert.Ignore guard to cover the action-invoke and discovery-request send paths so the tests degrade gracefully where multicast loopback is unroutable, while still exercising fully on platforms that support it. --- .../Application/PubSubActionRuntimeTests.cs | 5 ++ .../Application/PubSubDiscoveryTests.cs | 57 +++++++++++-------- 2 files changed, 39 insertions(+), 23 deletions(-) diff --git a/Tests/Opc.Ua.PubSub.Tests/Application/PubSubActionRuntimeTests.cs b/Tests/Opc.Ua.PubSub.Tests/Application/PubSubActionRuntimeTests.cs index 34fafbebcf..214fe740d4 100644 --- a/Tests/Opc.Ua.PubSub.Tests/Application/PubSubActionRuntimeTests.cs +++ b/Tests/Opc.Ua.PubSub.Tests/Application/PubSubActionRuntimeTests.cs @@ -135,6 +135,11 @@ public async Task UdpLoopbackActionResponderAnswersRequesterAsync() TimeSpan.FromSeconds(2), cts.Token).ConfigureAwait(false); } + catch (Exception ex) when (IsUdpEnvironmentFailure(ex)) + { + Assert.Ignore("UDP multicast loopback is not available in this environment: " + ex.Message); + return; + } catch (TimeoutException) { Assert.Ignore("UDP multicast loopback did not deliver Action responses."); diff --git a/Tests/Opc.Ua.PubSub.Tests/Application/PubSubDiscoveryTests.cs b/Tests/Opc.Ua.PubSub.Tests/Application/PubSubDiscoveryTests.cs index c582569a35..2dae5a4f57 100644 --- a/Tests/Opc.Ua.PubSub.Tests/Application/PubSubDiscoveryTests.cs +++ b/Tests/Opc.Ua.PubSub.Tests/Application/PubSubDiscoveryTests.cs @@ -126,29 +126,40 @@ public async Task UdpLoopbackDiscoveryPublisherAnswersSubscriberRequests() return; } - PubSubDiscoveryResult metaData = await subscriber.RequestDiscoveryAsync( - new PubSubDiscoveryRequest - { - DiscoveryType = UadpDiscoveryType.DataSetMetaData, - DataSetWriterIds = [DataSetWriterIdValue] - }, - TimeSpan.FromSeconds(1), - cts.Token).ConfigureAwait(false); - PubSubDiscoveryResult writerConfiguration = await subscriber.RequestDiscoveryAsync( - new PubSubDiscoveryRequest - { - DiscoveryType = UadpDiscoveryType.DataSetWriterConfiguration, - DataSetWriterIds = [DataSetWriterIdValue] - }, - TimeSpan.FromSeconds(1), - cts.Token).ConfigureAwait(false); - PubSubDiscoveryResult endpoints = await subscriber.RequestDiscoveryAsync( - new PubSubDiscoveryRequest - { - DiscoveryType = UadpDiscoveryType.PublisherEndpoints - }, - TimeSpan.FromSeconds(1), - cts.Token).ConfigureAwait(false); + PubSubDiscoveryResult metaData; + PubSubDiscoveryResult writerConfiguration; + PubSubDiscoveryResult endpoints; + try + { + metaData = await subscriber.RequestDiscoveryAsync( + new PubSubDiscoveryRequest + { + DiscoveryType = UadpDiscoveryType.DataSetMetaData, + DataSetWriterIds = [DataSetWriterIdValue] + }, + TimeSpan.FromSeconds(1), + cts.Token).ConfigureAwait(false); + writerConfiguration = await subscriber.RequestDiscoveryAsync( + new PubSubDiscoveryRequest + { + DiscoveryType = UadpDiscoveryType.DataSetWriterConfiguration, + DataSetWriterIds = [DataSetWriterIdValue] + }, + TimeSpan.FromSeconds(1), + cts.Token).ConfigureAwait(false); + endpoints = await subscriber.RequestDiscoveryAsync( + new PubSubDiscoveryRequest + { + DiscoveryType = UadpDiscoveryType.PublisherEndpoints + }, + TimeSpan.FromSeconds(1), + cts.Token).ConfigureAwait(false); + } + catch (Exception ex) when (IsUdpEnvironmentFailure(ex)) + { + Assert.Ignore("UDP multicast loopback is not available in this environment: " + ex.Message); + return; + } if (metaData.DataSetMetaDataEntries.Count == 0 || writerConfiguration.WriterConfigurations.Count == 0 From aca14d1a14bde21a2250bbd37adf874d763b16f4 Mon Sep 17 00:00:00 2001 From: Marc Schier Date: Sun, 28 Jun 2026 15:45:00 +0200 Subject: [PATCH 116/125] Harden DTLS Certificate handle ownership and disposal Audit + fix of the Certificate/CertificateCollection reference-counting and disposal in the PubSub DTLS subsystem (the only place in the PR that owns certificate handles). No direct X509Certificate2 usage exists in the PR; the last-mile key extraction (GetECDsaPrivateKey/PublicKey, RawData) is unchanged. - DtlsCertificateAuthenticator.DecodeCertificate now returns a CertificateCollection (owned, disposable) instead of List, and builds it leak-safely: each decoded handle is added (CertificateCollection.Add takes its own AddRef) and the transient handle disposed, with the whole collection disposed if decoding throws part way (previously the partially decoded handles leaked on the exception path). - DtlsHandshakeContext consumes the peer chain via `using CertificateCollection` on both client and server paths, replacing the manual try/finally foreach Dispose. - DefaultDtlsContextFactory.ResolveLocalCertificatesAsync returns a CertificateCollection and disposes it if resolution is cancelled mid-way (previously already-resolved handles leaked when ThrowIfCancellationRequested fired). ResolvedLocalCertificateDtlsContext owns and disposes that collection with a single Dispose; the DisposeCertificates helper is removed. Effective options hold documented borrowed aliases valid for the collection's lifetime. - DtlsTransportOptions.LocalCertificates documents its borrow contract (the registrant owns/disposes; the stack only AddRefs for the handshake duration). - Tests: peer-chain assertions use `using CertificateCollection`; added DecodeCertificateDisposesEveryDecodedHandle which asserts (via Certificate.InstancesCreated/InstancesDisposed) that disposing a decoded chain releases every handle it created.

Like ClientCertificateSubject, only public CA certs are referenced so no certificate material is embedded in configuration files. - IMqttTrustedIssuerResolver + default TrustedIssuerStoreResolver: resolve the subjects against SecurityConfiguration.TrustedIssuerCertificates into an owned CertificateCollection (AddRef'd; caller disposes). Optional, DI-registered, with a direct-construct fallback (mirrors the DTLS optional-DI pattern). - MqttClientAdapter wires the resolved chain into the handshake: MQTTnet v5 (net8+) via WithTrustChain; MQTTnet v4 (net48/net472/netstandard2.1) via a custom, fail-closed certificate-validation handler that only accepts a broker certificate that chains to a configured CA. The chain is consulted only while ValidateServerCertificate is true; otherwise the platform default trust store is used. The resolved CertificateCollection is converted last-mile to an owned X509Certificate2Collection that the adapter keeps alive for the connection and disposes on Dispose / reconnect. - Tests: MqttTlsOptions surface; resolver matches by subject and thumbprint, ignores unknown subjects, returns an independently disposable collection, and no-config/no-subjects paths return empty. - Docs: Docs/PubSub.md MQTT TLS configuration section.

Verified: Opc.Ua.PubSub.Mqtt builds 0-warning on net8.0/net10.0 (v5) and net48/netstandard2.1 (v4); Opc.Ua.PubSub.Mqtt.Tests 148/148 pass on net10.0 (incl. 9 new tests); test project builds under net48 and netstandard2.1 pins. --- Docs/PubSub.md | 28 +++ ...qttTransportServiceCollectionExtensions.cs | 2 + .../Internal/IMqttTrustedIssuerResolver.cs | 73 ++++++ .../Internal/MqttClientAdapter.cs | 144 +++++++++-- .../Internal/MqttClientAdapterFactory.cs | 17 +- .../Internal/TrustedIssuerStoreResolver.cs | 169 +++++++++++++ .../Opc.Ua.PubSub.Mqtt/MqttTlsOptions.cs | 17 ++ .../MqttTlsOptionsTests.cs | 78 ++++++ .../TrustedIssuerStoreResolverTests.cs | 225 ++++++++++++++++++ 9 files changed, 733 insertions(+), 20 deletions(-) create mode 100644 Libraries/Opc.Ua.PubSub.Mqtt/Internal/IMqttTrustedIssuerResolver.cs create mode 100644 Libraries/Opc.Ua.PubSub.Mqtt/Internal/TrustedIssuerStoreResolver.cs create mode 100644 Tests/Opc.Ua.PubSub.Mqtt.Tests/MqttTlsOptionsTests.cs create mode 100644 Tests/Opc.Ua.PubSub.Mqtt.Tests/TrustedIssuerStoreResolverTests.cs diff --git a/Docs/PubSub.md b/Docs/PubSub.md index 1b3b0b218c..f0d239e325 100644 --- a/Docs/PubSub.md +++ b/Docs/PubSub.md @@ -574,6 +574,34 @@ var options = new MqttConnectionOptions }; ``` +#### MQTT TLS configuration + +`MqttConnectionOptions.Tls` (`MqttTlsOptions`) controls the TLS handshake for `mqtts://` +and `wss://` endpoints. The broker certificate chain can be validated against a configured +set of certificate authorities via `TrustedIssuerCertificateSubjects` — a list of CA +subject distinguished names (or thumbprints) resolved from the application's trusted issuer +certificate store (`SecurityConfiguration.TrustedIssuerCertificates`).

The DTLS 1.3 handshake is implemented, including ECDHE negotiation, HelloRetryRequest cookies, and certificate authentication. The key schedule/HKDF, AEAD record protection, and anti-replay window are implemented for the registered runtime profiles. diff --git a/Libraries/Opc.Ua.PubSub.Mqtt/DependencyInjection/MqttTransportServiceCollectionExtensions.cs b/Libraries/Opc.Ua.PubSub.Mqtt/DependencyInjection/MqttTransportServiceCollectionExtensions.cs index 4fdd42c88b..a234bfa3fa 100644 --- a/Libraries/Opc.Ua.PubSub.Mqtt/DependencyInjection/MqttTransportServiceCollectionExtensions.cs +++ b/Libraries/Opc.Ua.PubSub.Mqtt/DependencyInjection/MqttTransportServiceCollectionExtensions.cs @@ -139,6 +139,8 @@ public static IPubSubBuilder AddMqttTransport( private static void RegisterShared(IServiceCollection services) { + services.TryAddSingleton(sp => + new TrustedIssuerStoreResolver(sp.GetService())); services.TryAddSingleton(); services.Add( ServiceDescriptor.Singleton(sp => diff --git a/Libraries/Opc.Ua.PubSub.Mqtt/Internal/IMqttTrustedIssuerResolver.cs b/Libraries/Opc.Ua.PubSub.Mqtt/Internal/IMqttTrustedIssuerResolver.cs new file mode 100644 index 0000000000..39422f1e26 --- /dev/null +++ b/Libraries/Opc.Ua.PubSub.Mqtt/Internal/IMqttTrustedIssuerResolver.cs @@ -0,0 +1,73 @@ +/* ======================================================================== + * Copyright (c) 2005-2026 The OPC Foundation, Inc.

It works for the encodeable types emitted by the source generators and for complex types that are added dynamically by the complex-type client. Schemas are produced in every supported encoding: + +- **XSD** for the XML encoding. +- **BSD** (OPC Binary, Part 6) for the binary encoding. +- **JSON Schema** (Part 6 Annex C, draft 2020-12) for the JSON encoding, in both the **compact** (reversible, BrowseName-keyed) and **verbose** flavors. + +Schemas are built as strongly-typed object models in code — there are no embedded schema strings — so unused generation paths are trimmed away and the whole library is NativeAOT compatible. The XSD object model is the in-box `System.Xml.Schema.XmlSchema`, the BSD object model is the existing `Opc.Ua.Schema.Binary.TypeDictionary`, and the JSON object model is `System.Text.Json.Nodes.JsonObject`. + +## Concepts + +Generation is driven by a type's runtime structure definition (`StructureDefinition` or `EnumDefinition`), which already captures every field, data type, value rank and optionality. The pieces fit together as follows: + +- `ISchemaProvider` is the entry point. It produces an `IUaSchema` for a requested `UaSchemaFormat` and `UaSchemaScope`. +- `IUaSchema` is the generated document. It exposes the strongly-typed object model (for example `JsonSchemaDocument.Root`, `XmlSchemaDocument.Schema`, `BinarySchemaDocument.Dictionary`) and can serialize itself with `WriteTo(Stream)`, `WriteTo(TextWriter)` or `ToSchemaString()`. +- `IDataTypeDefinitionResolver` maps a data type id to its `UaTypeDescription` (the type id, browse name and definition). The default implementation, `DataTypeDefinitionRegistry`, is an in-memory registry that generated and dynamically built types register their definitions with. The resolver is also used to follow field references and to enumerate the types of a namespace. + +`UaSchemaFormat` selects the encoding (`Xsd`, `Bsd`, `JsonCompact`, `JsonVerbose`). `UaSchemaScope` selects the document granularity: `Type` produces a document for a single type and the closure of the types it depends on; `Namespace` produces a dictionary document for all types in a namespace. + +## Registration + +The services are registered through the standard OPC UA dependency-injection surface: + +```csharp +IServiceProvider services = new ServiceCollection() + .AddOpcUa() + .AddSchemaGeneration() + .Services + .BuildServiceProvider(); + +ISchemaProvider provider = services.GetRequiredService(); +``` + +The provider can also be constructed directly when dependency injection is not used: + +```csharp +var registry = new DataTypeDefinitionRegistry(); +registry.Add(new UaTypeDescription(typeId, browseName, structureDefinition, namespaceUri)); + +ISchemaProvider provider = new DefaultSchemaProvider( + registry, + new IUaSchemaGenerator[] { new JsonSchemaGenerator() }); +``` + +## Registering data types + +Schema generation needs the runtime definition of a type. A type's `StructureDefinition` / `EnumDefinition` is registered with the resolver from whichever source has it: + +- **Server / browsed types** — a `DataTypeNode` obtained from a server (or the client node cache) carries its definition in `DataTypeNode.DataTypeDefinition`. Register it directly: + +```csharp +var registry = serviceProvider.GetRequiredService(); +registry.TryAddDataType(dataTypeNode, session.NamespaceUris); +``` + +- **Source-generated types** — the generated types expose their definition through the generated `DataTypeDefinitions.Create(namespaceUris)` factory. Wrap it in a `UaTypeDescription` and add it: + +```csharp +registry.Add(new UaTypeDescription(typeId, browseName, definition, namespaceUri)); +``` + +- **Dynamic complex types** — complex types built by the complex-type client carry a `StructureDefinition` (via `IStructureTypeInfo` / the structure-definition attribute) that can likewise be wrapped in a `UaTypeDescription` and registered. + +Once registered, fields that reference other registered types are resolved automatically and included in the generated document. + +## Generating a schema + +Once a type's definition is registered with the resolver, a schema can be produced from its type id: + +```csharp +if (provider.TryGetSchema(typeId, UaSchemaFormat.JsonCompact, UaSchemaScope.Type, out IUaSchema? schema)) +{ + string json = schema.ToSchemaString(); +} +``` + +The convenience extension methods read more naturally and make a type "expose" its schema: + +```csharp +IUaSchema xsd = provider.GetXmlSchema(type); +IUaSchema bsd = provider.GetBinarySchema(type); +IUaSchema jsonCompact = provider.GetJsonSchema(type); +IUaSchema jsonVerbose = provider.GetJsonSchema(type, verbose: true); + +// Resolve by type id and produce JSON in one call. +provider.TryGetJsonSchema(typeId, out IUaSchema? schema); +``` + +## Working with the object model + +Because the schema is an object model, callers can inspect or post-process it before serializing. For JSON: + +```csharp +var document = (JsonSchemaDocument)provider.GetJsonSchema(type); +JsonObject root = document.Root; // the draft 2020-12 schema +document.WriteTo(stream); // UTF-8, indented +``` + +## JSON encoding notes (Part 6) + +The JSON schemas follow the Part 6 JSON encoding faithfully, matching what the stack's `JsonEncoder` produces: + +- `Int64` and `UInt64` are encoded as JSON strings (to avoid precision loss), so they are typed as `string`. +- `Float`/`Double` accept the special string values `Infinity`, `-Infinity` and `NaN`, so they are typed as `["number", "string"]`. +- `ByteString` is a base64 `string`; `DateTime` is a `date-time` string; `Guid` is a `uuid` string. +- The standard structured built-ins (`NodeId`, `Variant`, `ExtensionObject`, `DataValue`, ...) are described once per document in the `$defs` section and referenced. +- Compact enums are integers (with the allowed values listed via `oneOf`); verbose enums are the `Name_Value` strings. + +## PubSub schemas + +The `Opc.Ua.PubSub.Schema` library generates JSON Schemas for the PubSub JSON message formats. It is registered with `services.AddOpcUa().AddPubSubSchema()` and exposes `IPubSubSchemaProvider`: + +- `CreateDataSetSchema(metaData, fieldContentMask, verbose)` — the per-DataSet payload object, one property per `FieldMetaData`. The field value shape follows the same Part 6 JSON rules as the core library, and `DataSetFieldContentMask` controls whether each field is the raw value or a `DataValue` object (with the mask-selected `StatusCode` / `SourceTimestamp` / ... members). +- `CreateDataSetMessageSchema(metaData, messageContentMask, fieldContentMask, verbose)` — a single DataSetMessage whose header fields are gated by `JsonDataSetMessageContentMask` and whose `Payload` is the DataSet schema above. +- `CreateNetworkMessageSchema(metaData, networkContentMask, messageContentMask, fieldContentMask, verbose)` — the `ua-data` NetworkMessage envelope, gated by `JsonNetworkMessageContentMask`; `Messages` is an array of DataSetMessage schemas, or a single object when `SingleDataSetMessage` is set. +- `CreateMetaDataMessageSchema(metaData, verbose)` — the `ua-metadata` message. + +The provider reuses the core `ISchemaProvider` to resolve complex (structured/enum) field data types, embedding them into the document `$defs` section. + +## Trimming and NativeAOT + +The library opts into `IsAotCompatible` and avoids reflection-based serialization. XSD is written with `System.Xml.Schema.XmlSchema`, BSD with a direct `System.Xml.XmlWriter`, and JSON with `System.Text.Json.Nodes` / `Utf8JsonWriter`. Schema generation is a configuration-time activity, not a hot path; documents are built lazily and can be cached by the caller. Because the generation logic lives in its own assembly, it is trimmed away entirely when an application does not generate schemas. diff --git a/Libraries/Opc.Ua.Client.ComplexTypes/Opc.Ua.Client.ComplexTypes.csproj b/Libraries/Opc.Ua.Client.ComplexTypes/Opc.Ua.Client.ComplexTypes.csproj index 61e363cef0..f95396548d 100644 --- a/Libraries/Opc.Ua.Client.ComplexTypes/Opc.Ua.Client.ComplexTypes.csproj +++ b/Libraries/Opc.Ua.Client.ComplexTypes/Opc.Ua.Client.ComplexTypes.csproj @@ -11,6 +11,14 @@ true enable + + + true + diff --git a/Libraries/Opc.Ua.Client/ComplexTypes/ComplexTypeSystem.cs b/Libraries/Opc.Ua.Client/ComplexTypes/ComplexTypeSystem.cs index 3f6672f9b0..2c66df8ce9 100644 --- a/Libraries/Opc.Ua.Client/ComplexTypes/ComplexTypeSystem.cs +++ b/Libraries/Opc.Ua.Client/ComplexTypes/ComplexTypeSystem.cs @@ -35,6 +35,7 @@ using System.Threading.Tasks; using System.Xml; using Microsoft.Extensions.Logging; +using Opc.Ua.Schema; namespace Opc.Ua.Client.ComplexTypes { @@ -396,6 +397,40 @@ public IEnumerable GetDefinedDataTypeIds() NodeId.ToExpandedNodeId(nodeId, m_complexTypeResolver.NamespaceUris)); } + /// + /// Registers the data type definitions loaded by this complex type system for schema generation. + /// + /// The registry to populate. + /// The registry to allow chaining. + /// is null. + public DataTypeDefinitionRegistry RegisterDataTypeDefinitions(DataTypeDefinitionRegistry registry) + { + if (registry == null) + { + throw new ArgumentNullException(nameof(registry)); + } + + foreach (KeyValuePair entry in m_dataTypeDefinitionCache) + { + NodeId nodeId = entry.Key; + string namespaceUri = m_complexTypeResolver.NamespaceUris.GetString(nodeId.NamespaceIndex) ??

Under the netstandard2.1 solution pin the library builds as netstandard2.1 (no Pcap) while Opc.Ua.PubSub.Eth.Tests builds as net8.0, so the test's NET8_0_OR_GREATER-guarded WithPcapReplacesChannelFactory referenced WithPcap()/Channels.Pcap which the referenced library does not expose (CS1061/CS0234), failing the linux all-TFM build. Introduce an ETH_PCAP compile constant (defined only when the test targets net8.0+ AND the solution is not pinned to netstandard2.1) and gate the Pcap test on it instead of the test's own TFM, mirroring the MQTTNET_V5 approach.

From f4ca52adaff31b791690c285ffdf29f575b2a23b Mon Sep 17 00:00:00 2001 From: Marc Schier Date: Tue, 30 Jun 2026 11:58:02 +0200 Subject: [PATCH 125/125] Consolidate TFM-support warning suppression to common.props (#3927) Microsoft.Extensions.Http.Resilience and its transitive Telemetry / AmbientMetadata / Diagnostics graph ship net462 assets that build and run on .NET Framework, but their buildTransitive support targets still emit "doesn't support net48/net472" warnings. These warnings were previously silenced by 12 scattered, inconsistent per-project SuppressTfmSupportBuildWarnings blocks that only covered a subset of the projects that actually emit them. Replace the per-project blocks with a single net472/net48-scoped suppression in common.props so every project is covered consistently, keeping full TFM support (no gating, no per-TFM public API change). Verified: a net48 UA.slnx build now emits zero "doesn't support net48" warnings (previously hundreds), and net10 builds remain unaffected (the suppression is net4x-only).
