From 54b18f984364a0b33640786c795be853d4650d09 Mon Sep 17 00:00:00 2001 From: Tennessee Carmel-Veilleux Date: Tue, 21 Jun 2022 14:38:11 -0400 Subject: [PATCH 01/44] Implement shadow fail-safe data in FabricTable - FabricTable management during commissioning did not properly handle the fact that committing needs to only be done on CommissioningComplete, which prevented the AddTrustedRootCertificate, UpdateNOC and AddNOC command semantics to be implemented properly and prevented proper state observation of operational credential clusters server Fixes #7695 Issue #8905 Fixes #18633 Issue #17208 Fixes #15585 This PR: - Removes direct access to FabricInfo from everywhere, which caused possibly stale FabricInfo references during commissioning. - Remove immediate committing of fabric table on UpdateNOC. - Make Fabrics, NOCs and TrustedRootCertificates attributes reflect proper partial state during fail-safe, by using the shadow data capabilities of OperationalCertificateStore and by updates to FabricInfo - Make it possible to unit test fabric table by providing the necessary lifecycle public APIs to test every modality of the commissioning flow - Make Server and DeviceController use OperationalCertificateStore to allow proper external lifecycle management of the operational cert chain. - Update all examples/controller code to new API - Remove dangerous internal APIs from FabricTable and replace with direct accessors where needed - Add more of the necessary spec validations to the UpdateNOC and AddNOC flows Testing done: - Updated all unit tests, all pass - Cert tests still pass as before - Working on further integration tests and unit tests as a follow-up noting that current state has not regressed on existing test coverage, and that new usage of OperationalCertificateStore class in FabricTable gains a large amount of additional coverage transitively via some of the existing tests making use of FabricTable. --- .../chip-tool/commands/common/CHIPCommand.cpp | 21 +- .../chip-tool/commands/common/CHIPCommand.h | 2 + examples/chip-tool/commands/group/Commands.h | 2 +- examples/platform/linux/CommissionerMain.cpp | 12 +- examples/shell/shell_common/cmd_ping.cpp | 460 +----- examples/shell/shell_common/cmd_send.cpp | 385 +---- src/app/clusters/bindings/BindingManager.cpp | 6 +- .../door-lock-server/door-lock-server.cpp | 6 +- .../group-key-mgmt-server.cpp | 2 +- .../operational-credentials-server.cpp | 244 ++- src/app/server/Server.cpp | 14 +- src/app/server/Server.h | 24 +- src/app/tests/TestWriteInteraction.cpp | 2 +- .../tests/integration/chip_im_initiator.cpp | 3 - .../tests/integration/chip_im_responder.cpp | 3 - src/app/tests/integration/common.cpp | 28 + src/controller/CHIPDeviceController.cpp | 197 ++- src/controller/CHIPDeviceController.h | 79 +- .../CHIPDeviceControllerFactory.cpp | 26 +- src/controller/CHIPDeviceControllerFactory.h | 22 +- .../java/AndroidDeviceControllerWrapper.cpp | 27 +- .../java/AndroidDeviceControllerWrapper.h | 3 + .../ChipDeviceController-ScriptBinding.cpp | 7 +- src/controller/python/OpCredsBinding.cpp | 9 +- .../python/chip/internal/CommissionerImpl.cpp | 16 +- src/credentials/FabricTable.cpp | 1422 +++++++++++------ src/credentials/FabricTable.h | 436 +++-- src/credentials/OperationalCertificateStore.h | 45 + .../PersistentStorageOpCertStore.cpp | 2 +- .../PersistentStorageOpCertStore.h | 28 +- src/credentials/tests/TestFabricTable.cpp | 200 ++- .../TestPersistentStorageOpCertStore.cpp | 82 +- src/crypto/CHIPCryptoPAL.h | 1 + .../PersistentStorageOperationalKeystore.h | 4 + .../Framework/CHIP/CHIPDeviceController.mm | 20 +- .../Framework/CHIP/MatterControllerFactory.mm | 1 + src/lib/core/DataModelTypes.h | 9 + src/lib/core/PeerId.h | 13 +- .../support/TestPersistentStorageDelegate.h | 165 +- src/messaging/tests/MessagingContext.cpp | 28 +- src/messaging/tests/MessagingContext.h | 5 + src/messaging/tests/echo/echo_requester.cpp | 3 - src/messaging/tests/echo/echo_responder.cpp | 3 - src/protocols/secure_channel/CASESession.cpp | 18 +- .../secure_channel/tests/TestCASESession.cpp | 82 +- src/transport/tests/TestSessionManager.cpp | 190 ++- 46 files changed, 2346 insertions(+), 2011 deletions(-) diff --git a/examples/chip-tool/commands/common/CHIPCommand.cpp b/examples/chip-tool/commands/common/CHIPCommand.cpp index 4e10e67e74b2e8..475e3647d2a3d0 100644 --- a/examples/chip-tool/commands/common/CHIPCommand.cpp +++ b/examples/chip-tool/commands/common/CHIPCommand.cpp @@ -72,11 +72,13 @@ CHIP_ERROR CHIPCommand::MaybeSetUpStack() ReturnLogErrorOnFailure(mDefaultStorage.Init());

This reworks Last known Good Time to use the same strategy. Now, instead of persisting both last known good time and a fail-safe backup at the time of certificate installation, a single, updated last known good time is stored in RAM at the time of certificate installation. Then, on commit, this is persisted, but never before. --- .../operational-credentials-server.cpp | 10 -- src/credentials/FabricTable.cpp | 27 +++-- src/credentials/FabricTable.h | 18 ---- src/credentials/LastKnownGoodTime.cpp | 75 +++----------- src/credentials/LastKnownGoodTime.h | 44 ++------- src/credentials/tests/TestFabricTable.cpp | 98 +++++++------------ 6 files changed, 79 insertions(+), 193 deletions(-) diff --git a/src/app/clusters/operational-credentials-server/operational-credentials-server.cpp b/src/app/clusters/operational-credentials-server/operational-credentials-server.cpp index b6cbb81af5e861..6d306d381a22ce 100644 --- a/src/app/clusters/operational-credentials-server/operational-credentials-server.cpp +++ b/src/app/clusters/operational-credentials-server/operational-credentials-server.cpp @@ -338,11 +338,6 @@ void FailSafeCleanup(const chip::DeviceLayer::ChipDeviceEvent * event) { ChipLogError(Zcl, "OpCreds: failed to delete fabric at index %u: %" CHIP_ERROR_FORMAT, fabricIndex, err.Format()); } - err = Server::GetInstance().GetFabricTable().RevertLastKnownGoodChipEpochTime(); - if (err != CHIP_NO_ERROR) - { - ChipLogError(Zcl, "OpCreds: failed to revert Last Known Good Time: %" CHIP_ERROR_FORMAT, err.Format()); - } } // If an UpdateNOC command had been successfully invoked, revert the state of operational key pair, NOC and ICAC for that @@ -351,11 +346,6 @@ void FailSafeCleanup(const chip::DeviceLayer::ChipDeviceEvent * event) if (event->FailSafeTimerExpired.updateNocCommandHasBeenInvoked) { // TODO: Revert the state of operational key pair, NOC and ICAC - CHIP_ERROR err = Server::GetInstance().GetFabricTable().RevertLastKnownGoodChipEpochTime(); - if (err != CHIP_NO_ERROR) - { - ChipLogError(Zcl, "OpCreds: failed to revert Last Known Good Time: %" CHIP_ERROR_FORMAT, err.Format()); - } } } diff --git a/src/credentials/FabricTable.cpp b/src/credentials/FabricTable.cpp index f860221ec3db62..87155fa7546385 100644 --- a/src/credentials/FabricTable.cpp +++ b/src/credentials/FabricTable.cpp @@ -852,7 +852,18 @@ FabricTable::AddOrUpdateInner(FabricIndex fabricIndex, Crypto::P256Keypair * exi static_cast(fabricEntry->GetFabricIndex()), ChipLogValueX64(fabricEntry->GetNodeId())); } - mPendingLastKnownGoodTime = notBeforeCollector.mLatestNotBefore; + // Failure to update pending Last Known Good Time is non-fatal.
