Subject: [PATCH 06/11] ip6tnl: move route updating for redirect to ndisc layer
Date: Thu, 12 Sep 2013 18:49:24 +0800 [thread overview]
Message-ID: <52319C34.8000902@cn.fujitsu.com> (raw)
In-Reply-To: <52319A6E.6090503@cn.fujitsu.com>
From: Duan Jiong <duanj.fnst@cn•fujitsu.com>
In rfc2473, we can know that the tunnel ICMP redirect
message should not be reported to the source of the
original packet, so after calling ip6_tnl_err(), the
rel_msg is set to 0 in function ip4ip6_err(), and the
redirect will never be handled.
In order to deal with this, we move route updating for
redirect to ndisc layer.
