--- Comment #9 from Arturo Borrero Gonzalez <arturo at debian.org> ---
One more question.

In this line
http://lxr.free-electrons.com/source/net/netfilter/nf_conntrack_proto_tcp.c?v=4.1#L935

the code calls tcp_options() which parses the TCP header to fill our conntrack
entry (the 'seen' one).

In that function we don't put IP_CT_TCP_FLAG_BE_LIBERAL into flags, so a
later
check if (seen.flags & IP_CT_TCP_FLAG_BE_LIBERAL) should always fail.

It seems I'm missing something.
