Subject: [PATCH 4.8 16/49] net: icmp6_send should use dst dev to determine L3 domain
Date: Sat, 19 Nov 2016 10:23:08 +0100 [thread overview]
Message-ID: <20161119092039.182992597@linuxfoundation.org> (raw)
In-Reply-To: <20161119092036.698705716@linuxfoundation.org>
4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Ahern <dsa@cumulusnetworks.com>
[ Upstream commit 5d41ce29e3b91ef305f88d23f72b3359de329cec ]
icmp6_send is called in response to some event. The skb may not have
the device set (skb->dev is NULL), but it is expected to have a dst set.
Update icmp6_send to use the dst on the skb to determine L3 domain.
Fixes: ca254490c8dfd ("net: Add VRF support to IPv6 stack")
