Subject: [PATCH 2.4.37] iptables: handle IPT_RETURN from user target
Date: Wed, 18 Mar 2009 15:32:29 +0200 [thread overview]
Message-ID: <49C0F7ED.40106@expand.com> (raw)
This patch handles IPT_RETURN retcode for user's iptables' targets
(modules).
Up until now it was handled only for the built-in RETURN iptables' target
and IPT_RETURN in a user target resulted in a NF_DROP.
