Subject: [NETFILTER 04/04]: nf_nat_sip: don't drop short packets
Date: Tue, 14 Aug 2007 18:40:19 +0200 (MEST) [thread overview]
Message-ID: <20070814164011.14668.44375.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070814164004.14668.43960.sendpatchset@localhost.localdomain>
[NETFILTER]: nf_nat_sip: don't drop short packets
Don't drop packets shorter than "SIP/2.0", just ignore them. Keep-alives
can validly be shorter for example.
