Subject: [PATCH 3.16 20/55] ipv6: restore the behavior of ipv6_sock_ac_drop()
Date: Mon, 13 Oct 2014 04:24:34 +0200 [thread overview]
Message-ID: <20141013022444.586003834@linuxfoundation.org> (raw)
In-Reply-To: <20141013022443.729870634@linuxfoundation.org>
3.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: WANG Cong <xiyou.wangcong@gmail.com>
[ Upstream commit de185ab46cb02df9738b0d898b0c3a89181c5526 ]
It is possible that the interface is already gone after joining
the list of anycast on this interface as we don't hold a refcount
for the device, in this case we are safe to ignore the error.
What's more important, for API compatibility we should not
change this behavior for applications even if it were correct.
Fixes: commit a9ed4a2986e13011 ("ipv6: fix rtnl locking in setsockopt for anycast and multicast")
