If anyone has any objections, please let me know. ------------------ From: Matthieu Baerts (NGI0) 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.

The same operation can still be done at the same place, without using the new helper. ] Signed-off-by: Matthieu Baerts (NGI0) Signed-off-by: Greg Kroah-Hartman --- tools/testing/selftests/net/mptcp/pm_netlink.sh | 1 + 1 file changed, 1 insertion(+) --- a/tools/testing/selftests/net/mptcp/pm_netlink.sh +++ b/tools/testing/selftests/net/mptcp/pm_netlink.sh @@ -130,6 +130,7 @@ ip netns exec $ns1 ./pm_nl_ctl limits 1 check "ip netns exec $ns1 ./pm_nl_ctl limits" "$default_limits" "subflows above hard limit" ip netns exec $ns1 ./pm_nl_ctl limits 8 8 +ip netns exec $ns1 ./pm_nl_ctl flush check "ip netns exec $ns1 ./pm_nl_ctl limits" "accept 8 subflows 8" "set limits"
