From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx> 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.
