[PATCH 03/10] [PATCH] fix IPv6 per-socket multicast filtering in exact-match case

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


-stable review patch.  If anyone has any objections, please let us know.

per-socket multicast filters were not being applied to all sockets
in the case of an exact-match bound address, due to an over-exuberant
"return" in the look-up code. Fix below. IPv4 does not have this problem.

Thanks to Hoerdt Mickael for reporting the bug.
