From 38f7efd52c4f3f0b22c460eadbfe7c42f9ebff82 Mon Sep 17 00:00:00 2001 From: Faidon Liambotis Date: Tue, 21 Nov 2006 21:46:02 -0800 Subject: [PATCH] [NETFILTER]: H.323 conntrack: fix crash with CONFIG_IP_NF_CT_ACCT H.323 connection tracking code calls ip_ct_refresh_acct() when processing RCFs and URQs but passes NULL as the skb. When CONFIG_IP_NF_CT_ACCT is enabled, the connection tracking core tries to derefence the skb, which results in an obvious panic. A similar fix was applied on the SIP connection tracking code some time ago. Signed-off-by: Faidon Liambotis Signed-off-by: Patrick McHardy Signed-off-by: David S.
