This commit adds tests to cover the handling of Src Match entries,
including adding, removing and clearing of short addr entries and
extended addr entries.
This commit introduces a new mechanism for the TREL link to detect and
handle discrepancies between the IPv6 address and port used by a TREL
peer in a received TREL packet, and the information previously
reported by the platform layer (through DNS-SD discovery) for the
same peer.
Ideally, the platform underlying DNS-SD should detect changes to
advertised ports and addresses by peers. However, there are
situations where this is not detected reliably.
As a received frame over the TREL radio link is processed by the MAC
or MLE layers, if the frame passes receive security checks at either
layer (indicating it is a secure and authenticated/fresh frame from a
valid neighbor), the TREL peer socket address is automatically
updated from the received TREL packet info. This ensures the TREL
peer table is updated correctly if there are changes to TREL peer
addresses of valid Thread neighbors upon rx from such neighbor,
increasing the robustness of the TREL link.
This commit also introduces a new `otPlatTrel` platform API,
`otPlatTrelNotifyPeerSocketAddressDifference()`. The TREL
implementation now notifies the platform layer whenever it detects a
discrepancy in a TREL peer's socket address, regardless of whether
the peer table is automatically updated. This allows the platform
layer to take any appropriate action, such as restarting or
confirming DNS-SD service resolution query for the peer service
instance and/or address resolution query for its associated host
name.
This commit also adds a new test that validates the newly added
behavior, including the auto-update of peer table information and
notification of the platform through the new API, triggered by either
MLE or MAC messages over the TREL radio link.
When the ot-rcp enters the assert state, the host crashes and exits.
But the ot-rcp still runs in the dead loop and becomes an orphan
process.
This commit enables the platform assert so that the ot-rcp can
automatically exit when entering the assert state.
This commit adds some missing platform API implementation for
FakePlatform.
These are added so that FakePlatform can be used to write unit tests
in ot-br-posix.
The commit also guards the microSecondTimer code in `FakePlatform`
with the marcro `OPENTHREAD_CONFIG_PLATFORM_USEC_TIMER_ENABLE` because
`otPlatAlarmMicroFired` is only defined in OT timer.cpp when
`OPENTHREAD_CONFIG_PLATFORM_USEC_TIMER_ENABLE` is true.
This commit also removes some parameter names in the fake
implementation to avoid unused warnings.
This commit adds a fake platform for unit/component tests. This platform
uses virtual time so it should be able to run fast.
Note that the fake platforms leverage C++ virtual methods to allow mocking.
This commit verifies setting active dataset triggers the active dataset
change event by the notifier.
