Here, the "del/add id 0" steps are done 3 times to unsure this case is validated. 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. Fixes: 3ad14f54bd74 ("mptcp: more accurate MPC endpoint tracking") Cc: stable@vger.kernel.org Reviewed-by: Mat Martineau Signed-off-by: Matthieu Baerts (NGI0) --- v2: - Make the connection longer, to have time to finish all the endpoints manipulations when executed in slow environments. At the end of the operations, the connection is killed, so it doesn't make the test longer.
