From f833470c27832136d4416d8fc55d658082af0989 Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" matttbe@kernel.org Date: Sat, 27 Jul 2024 12:01:29 +0200 Subject: [PATCH] selftests: mptcp: join: check backup support in signal endp
Before the previous commit, 'signal' endpoints with the 'backup' flag were ignored when sending the MP_JOIN.
The MPTCP Join selftest has then been modified to validate this case: the "single address, backup" test, is now validating the MP_JOIN with a backup flag as it is what we expect it to do with such name. The previous version has been kept, but renamed to "single address, switch to backup" to avoid confusions.
The "single address with port, backup" test is also now validating the MPJ with a backup flag, which makes more sense than checking the switch to backup with an MP_PRIO.
The "mpc backup both sides" test is now validating that the backup flag is also set in MP_JOIN from and to the addresses used in the initial subflow, using the special ID 0.
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 validates the previous 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
