From 42cf93cd464e0df3c85d298c647411bae6d99e6e Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Tue, 21 Feb 2006 13:37:35 -0800 Subject: [NETFILTER]: Fix bridge netfilter related in xfrm_lookup The bridge-netfilter code attaches a fake dst_entry with dst->ops == NULL to purely bridged packets. When these packets are SNATed and a policy lookup is done, xfrm_lookup crashes because it tries to dereference dst->ops. Change xfrm_lookup not to dereference dst->ops before checking for the DST_NOXFRM flag and set this flag in the fake dst_entry. Signed-off-by: Patrick McHardy Signed-off-by: David S.
