Subject: [PATCH 4.1 09/29] net/ipv6: Correct PIM6 mrt_lock handling
Date: Thu, 1 Oct 2015 11:31:45 +0200 [thread overview]
Message-ID: <20151001093146.114903747@linuxfoundation.org> (raw)
In-Reply-To: <20151001093145.730759857@linuxfoundation.org>
4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Laing <richard.laing@alliedtelesis.co.nz>
[ Upstream commit 25b4a44c19c83d98e8c0807a7ede07c1f28eab8b ]
In the IPv6 multicast routing code the mrt_lock was not being released
correctly in the MFC iterator, as a result adding or deleting a MIF would
cause a hang because the mrt_lock could not be acquired.
This fix is a copy of the code for the IPv4 case and ensures that the lock
is released correctly.
