From 6ce0c8dfdfdacc4d370ccd51fa5d4cd28118a9cf Mon Sep 17 00:00:00 2001 From: David Stevens Date: Thu, 15 Sep 2005 13:46:06 -0600 Subject: [PATCH] [PATCH] fix IPv6 per-socket multicast filtering in exact-match case 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.
