From 2bbb21168a90c788e12fe722eb66f27e611e7df7 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Tue, 25 Mar 2008 20:24:24 -0700 Subject: [NETFILTER]: nf_conntrack_sip: introduce URI and header parameter parsing helpers Introduce URI and header parameter parsing helpers. These are needed by the conntrack helper to parse expiration values in Contact: header parameters and by the NAT helper to properly update the Via-header rport=, received= and maddr= parameters.
