From ffed53d25bf36efb0571f7d9109f2e95df7f8b33 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Tue, 9 Jan 2007 14:33:49 -0800 Subject: [PATCH] [NETFILTER]: nf_nat: fix hanging connections when loading the NAT module When loading the NAT module, existing connection tracking entries don't have room for NAT information allocated and packets are dropped, causing hanging connections. They really should be entered into the NAT table as NULL mappings, but the current allocation scheme doesn't allow this. For now simply accept those packets to avoid the hanging connections.
