Subject: [PATCH 04/13] Revert "netfilter: xt_connlimit: connlimit-above early loop termination"
Date: Wed,  2 Mar 2011 13:12:44 +0100	[thread overview]
Message-ID: <1299067973-15977-5-git-send-email-kaber@trash.net> (raw)
In-Reply-To: <1299067973-15977-1-git-send-email-kaber@trash.net>

From: Stefan Berger <stefanb@linux.vnet.ibm.com>

This reverts commit 44bd4de9c2270b22c3c898310102bc6be9ed2978.

I have to revert the early loop termination in connlimit since it generates
problems when an iptables statement does not use -m state --state NEW before
the connlimit match extension.
