From c0353c7b5da4cbd2ab8227e84bbc9c79890f24ce Mon Sep 17 00:00:00 2001 From: Aydin Arik Date: Fri, 14 Jun 2013 18:56:31 +1200 Subject: [PATCH] ipv4: Fixed MD5 key lookups when adding/ removing MD5 to/ from TCP sockets. MD5 key lookups on a given TCP socket were being performed incorrectly. This fix alters parameter inputs to the MD5 lookup function tcp_md5_do_lookup, which is called by functions tcp_md5_do_add and tcp_md5_do_del. Specifically, the change now inputs the correct address and address family required to make a proper lookup. Signed-off-by: Aydin Arik Signed-off-by: David S.
