selftests: net/bridge : add tests for per vlan snooping with stp state changes

2025-04-23T12:02:20Z

Change ALL_TESTS definition to "test-per-line". Add the test case of per vlan snooping with port stp state change to forwarding and also vlan equivalent case in both bridge_igmp.sh and bridge_mld.sh.

selftests: net: bridge: increase IGMP/MLD exclude timeout membership interval

2024-05-15T10:42:17Z

When running the bridge IGMP/MLD selftests on debug kernels we can get spurious errors when setting up the IGMP/MLD exclude timeout tests because the membership interval is just 3 seconds and the setup has 2 seconds of sleep plus various validations, the one second that is left is not enough. Increase the membership interval from 3 to 5 seconds to make room for the setup validation and 2 seconds of sleep.

selftests: bridge_igmp: Remove unnecessary address deletion

2022-10-19T13:01:08Z

The test group address is added and removed in v2reportleave_test(). There is no need to delete it again during cleanup as it results in the following error message: # bash -x ./bridge_igmp.sh [...] + cleanup + pre_cleanup [...] + ip address del dev swp4 239.10.10.10/32 RTNETLINK answers: Cannot assign requested address + h2_destroy Solve by removing the unnecessary address deletion.

selftests: net: bridge: update IGMP/MLD membership interval value

2021-10-29T12:58:21Z

When I fixed IGMPv3/MLDv2 to use the bridge's multicast_membership_interval value which is chosen by user-space instead of calculating it based on multicast_query_interval and multicast_query_response_interval I forgot to update the selftests relying on that behaviour. Now we have to manually set the expected GMI value to perform the tests correctly and get proper results (similar to IGMPv2 behaviour).

selftests: net: bridge: factor out and rename sg state functions

2020-11-05T00:55:47Z

Factor out S,G entry state checking functions for existence, forwarding, blocking and timer to lib.sh so they can be later used by MLDv2 tests. Add brmcast_ suffix to their name to make the relation to the bridge explicit. Signed-off-by: Nikolay Aleksandrov Signed-off-by: Jakub Kicinski
