net: bridge: mcast: don't delete permanent entries when fast leave is enabled
When permanent entries were introduced by the commit below, they were exempt from timing out and thus igmp leave wouldn't affect them unless fast leave was enabled on the port which was added before permanent entries existed. It shouldn't matter if fast leave is enabled or not if the user added a permanent entry it shouldn't be deleted on igmp leave. Before: $ echo 1 > /sys/class/net/eth4/brport/multicast_fast_leave $ bridge mdb add dev br0 port eth4 grp 229.1.1.1 permanent $ bridge mdb show dev br0 port eth4 grp 229.1.1.1 permanent < join and leave 229.1.1.1 on eth4 > $ bridge mdb show $ After: $ echo 1 > /sys/class/net/eth4/brport/multicast_fast_leave $ bridge mdb add dev br0 port eth4 grp 229.1.1.1 permanent $ bridge mdb show dev br0 port eth4 grp 229.1.1.1 permanent < join and leave 229.1.1.1 on eth4 > $ bridge mdb show dev br0 port eth4 grp 229.1.1.1 permanent Fixes: ccb1c31a ("bridge: add flags to distinguish permanent mdb entires") Signed-off-by:Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by:
