From 1a4ac9870fb82eed56623d0f69ec59aa5bef85fe Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Mon, 14 May 2012 10:55:03 +0200 Subject: [PATCH] netfilter: nf_ct_tcp: extend log message for invalid ignored packets Extend log message if packets are ignored to include the TCP state, ie. replace: [ 3968.070196] nf_ct_tcp: invalid packet ignored IN= OUT= SRC=... by: [ 3968.070196] nf_ct_tcp: invalid packet ignored in state ESTABLISHED IN= OUT= SRC=... This information is useful to know in what state we were while ignoring the packet.
