From b59c270104f03960069596722fea70340579244d Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Fri, 6 Jan 2006 23:06:10 -0800 Subject: [NETFILTER]: Keep conntrack reference until IPsec policy checks are done Keep the conntrack reference until policy checks have been performed for IPsec NAT support. The reference needs to be dropped before a packet is queued to avoid having the conntrack module unloadable. Signed-off-by: Patrick McHardy Signed-off-by: David S.
