From 3408404a4c2a4eead9d73b0bbbfe3f225b65f492 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 24 Jan 2011 14:37:46 -0800 Subject: [PATCH] inetpeer: Use correct AVL tree base pointer in inet_getpeer(). Family was hard-coded to AF_INET but should be daddr->family. This fixes crashes when unlinking ipv6 peer entries, since the unlink code was looking up the base pointer properly. Reported-by: Eric Dumazet Signed-off-by: David S.
