From 935ff5bb8a1cfcdf8e60c8f5c794d0bbbc234437 Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" matttbe@kernel.org Date: Sat, 27 Jul 2024 12:01:27 +0200 Subject: [PATCH] selftests: mptcp: join: validate backup in MPJ
A peer can notify the other one that a subflow has to be treated as "backup" by two different ways: either by sending a dedicated MP_PRIO notification, or by setting the backup flag in the MP_JOIN handshake.
The selftests were previously monitoring the former, but not the latter. This is what is now done here by looking at these new MIB counters when validating the 'backup' cases:
MPTcpExtMPJoinSynBackupRx MPTcpExtMPJoinSynAckBackupRx
The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it will help to validate a new fix for an issue introduced by this commit ID.
FYI, there is no need to backport this patch to v5.10: the modified tests are not in this version. Some CI will not use these selftests, but the ones from the last stable version, so no need to worry here.
Cheers, Matt
