From d4156e8cd93f5772483928aaf4960120caebd789 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 7 Jul 2007 22:31:32 -0700 Subject: [NETFILTER]: nf_conntrack: reduce masks to a subset of tuples Since conntrack currently allows to use masks for every bit of both helper and expectation tuples, we can't hash them and have to keep them on two global lists that are searched for every new connection. This patch removes the never used ability to use masks for the destination part of the expectation tuple and completely removes masks from helpers since the only reasonable choice is a full match on l3num, protonum and src.u.all.
