Subject: [PATCH 3.10 20/41] rtnetlink: fix fdb notification flags
Date: Fri, 11 Apr 2014 09:09:51 -0700 [thread overview]
Message-ID: <20140411160934.268844793@linuxfoundation.org> (raw)
In-Reply-To: <20140411160932.865173041@linuxfoundation.org>
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolas Dichtel <nicolas.dichtel@6wind.com>
[ Upstream commit 1c104a6bebf3c16b6248408b84f91d09ac8a26b6 ]
Commit 3ff661c38c84 ("net: rtnetlink notify events for FDB NTF_SELF adds and
deletes") reuses the function nlmsg_populate_fdb_fill() to notify fdb events.
But this function was used only for dump and thus was always setting the
flag NLM_F_MULTI, which is wrong in case of a single notification.
Libraries like libnl will wait forever for NLMSG_DONE.
