Subject: [PATCH 2/7] netfilter: nf_nat_proto_icmpv6:: fix wrong comparison in icmpv6_manip_pkt
Date: Wed, 18 Sep 2013 00:07:29 +0200 [thread overview]
Message-ID: <1379455654-3905-3-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1379455654-3905-1-git-send-email-pablo@netfilter.org>
From: Phil Oester <kernel@linuxace.com>
In commit 58a317f1 (netfilter: ipv6: add IPv6 NAT support), icmpv6_manip_pkt
was added with an incorrect comparison of ICMP codes to types. This causes
problems when using NAT rules with the --random option. Correct the
comparison.
This closes netfilter bugzilla #851, reported by Alexander Neumann.
