Date: Fri, 14 Jun 2013 18:56:31 +1200 From: Aydin Arik <aydin.arik@...iedtelesis.co.nz> To: "David S. Miller" <davem@...emloft.net>, Alexey Kuznetsov <kuznet@....inr.ac.ru>, James Morris <jmorris@...ei.org>, Hideaki YOSHIFUJI <yoshfuji@...ux-ipv6.org>, Patrick McHardy <kaber@...sh.net> Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Aydin Arik <aydin.arik@...iedtelesis.co.nz> Subject: [PATCH 1/1] 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.
