From 40796c5e8f2a93008e9034b3110a7e7b1fa0fba0 Mon Sep 17 00:00:00 2001 From: David L Stevens Date: Wed, 14 Sep 2005 21:10:20 -0700 Subject: [PATCH] [IPV6]: Fix per-socket multicast filtering in sk_reuse 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. Signed-off-by: David L Stevens Signed-off-by: David S.
