This commit implements DUA features of Thread 1.2 DUA that involves
sending and processing Backbone query and answer:
- Extend address query to the Backbone Link
- Send BB.qry for Thread address query
- Send ADDR_ANS.ntf for BB.ans
- DAD process
- PBBR to send BB.qry on the Backbone link (3 times if not answered)
- PBBR to receive and handle BB.qry and sends BB.ans
- PBBR to receive BB.ans and sends ADDR_ERR.ntf if duplicated
- PRO_BB.ntf
- Send PRO_BB.ntf when DUA registration is updated
- Handle PRO_BB.ntf
- Add test_dua_dad.py to test the DAD process when it was successful
or duplicated
- Verify the normal DAD process
- Verify Address Query can be extended to the Backbone link
- Verify DAD duplicate is handled correctly
- Verify PRO_BB.ntf for duplicated DUA is handled correctly
- backbone/test_mlr_multicast_routing.py verifies the basic features
of Backbone multicast routing
- backbone/test_mlr_multicast_routing_timeout.py verifies that MLR
timeout works
- backbone/test_mlr_multicast_routing_commissioner_timeout.py verifies
that Commissioner MLR timeout works
This commit enhances Backbone Router to send BMLR.ntf on the backbone
link for Multicast Listeners.
- Send BMLR.ntf to the Backbone link
- Add Backbone test with packet verification
- Includes some revision to the Thread 1.2 Backbone CI scripts to make
it more stable
This commit allows running packet verification on a test info (.json)
directly without running the test procedure, which can be helpful for
developing and debugging packet verification code.
Thread 1.2 CI with OTBR and Backbone link:
- Run OTBR in Dockers with Backbone link
- Enhance node.py to work with OTBR Docker
- Add Packet Verification for 5.11.1
- incomplete, some steps can not pass yet, just to make sure
Backbone traffic verification works
- Support running multiple tests simultaneously (default: each test
run 3 instances)
- Build OTBR Docker using OpenThread PR code
- Upload code coverage in Docker
Some implementation details:
- Most existing code of node.py is shared by OTBR Docker
- Backbone related test scripts are found in
tests/scripts/thread-cert/backbone
- A new script tests/scripts/thread-cert/run_bbr_tests.py is added to
manage multiple running tests
- Test configuration differs according to PORT_OFFSET
- Backbone interface name: Backbone{PORT_OFFSET}
- Backbone network prefix: 91{PORT_OFFSET:02x}::/64
- Docker instance name: otbr_{PORT_OFFSET}_{nodeid}
- Output Files:
- Pcap:
- Thread: {test_name}_{PORT_OFFSET}.pcap
- Backbone: {test_name}_{PORT_OFFSET}_backbone.pcap
- Merged: {test_name}_{PORT_OFFSET}_merged.pcap
- Log: {test_name}_{PORT_OFFSET}.log
This commit runs Thread 1.1 certification tests with packet
verification for 1.2 build because Thread 1.2 certified devices are
supposed to be able to pass Thread 1.1 certification first.
Note: changes to test TOPOLOGY:
- Original: nodes use version=1.1 by default
- Now: nodes use version according to ENV, except explicitly specified
This commit introduces the packet verification (PV) framework for
certification tests.
- Add packet verification framework code
- Implement packet verification for cert 5.1.7 as a minimal
example. There will be more 1.1/1.2 tests with PV submitted in the
future.
- Download pre-built thread-wireshark binaries from
openthread/wireshark/releases for packet dissecting (used by
pyshark)
- Added a Github Action job for Packet Verification
According to PEP8, constants should be written in all capital letters.
This commit capitalizes these constants:
- thread_cert.TestCase.topology
- thread_cert.TestCase.support_ncp
- Update all test cases to inherit thread_cert.TestCase and update
topologies accordingly. The topologies should all be correct because
they are automatically generated, not hand written.
- Use default Thread version: 1.1
- Cleanup node tmp files in tmp directory according to the current
PORT_OFFSET in setUp. This is required by
test_reed_address_solicit_rejected.py and test_coap_observe.py since
they define multiple test functions in one TestCase.
- Removed call to set_extaddr64 because it's not necessary and causing
failures.
- Introduce BACKBONE_ROUTER option for Backbone Router function.
- Implement Backbone Router service registration.
- Add basic Backbone Router service.
- Primary Backbone Router restores its Dataset when reattached after
short reset, increases sequence number and re-register to Leader.
- Add configurable jitter for Backbone Router service registration.
- Add Backbone Router service test.
This commit introduces the first Thread 1.2 feature - enhanced keep
alive.
This commit also introduces the build config
OPENTHREAD_CONFIG_THREAD_VERSION to include/exclude Thread 1.2 code.
