commit 452690be7de2f91cc0de68cb9e95252875b33503 upstream.
This modification is linked to the parent commit where the received ADD_ADDR limit was accidentally reset when the endpoints were flushed.
To validate that, the test is now flushing endpoints after having set new limits, and before checking them.
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.

Signed-off-by: Jakub Kicinski kuba@kernel.org [ Conflicts in pm_netlink.sh, because some refactoring have been done later on: commit 3188309c8ceb ("selftests: mptcp: netlink: add 'limits' helpers") and commit c99d57d0007a ("selftests: mptcp: use pm_nl endpoint ops") are not in this version. The same operation can still be done at the same place, without using the new helper. ] Signed-off-by: Matthieu Baerts (NGI0) matttbe@kernel.org --- Note: this patch is validating the upstream's parent patch, commit 68fc0f4b0d25 ("mptcp: pm: kernel: flush: do not reset ADD_ADDR limit"), which has not been queued in the v5.10 queue yet. I'm already sending this patch, because I got the FAILED notification, and the resolution is the same as previous patches I sent earlier today. --- tools/testing/selftests/net/mptcp/pm_netlink.sh | 1 + 1 file changed, 1 insertion(+)
