From f92f871989c97a24d284ac60b0f880222ddf87ac Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 27 Feb 2006 13:03:10 -0800 Subject: [PATCH] [NETFILTER]: nf_queue: check if rerouter is present before using it Every rerouter needs to provide a save and a reroute function, we don't need to check for them. But we do need to check if a rerouter is registered at all for the current family, with bridging for example packets of unregistered families can hit nf_queue.
