Subject: [PATCH 3.16 01/55] netlink: reset network header before passing to taps
Date: Mon, 13 Oct 2014 04:24:15 +0200 [thread overview]
Message-ID: <20141013022443.786497525@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: Daniel Borkmann <dborkman@redhat.com>
[ Upstream commit 4e48ed883c72e78c5a910f8831ffe90c9b18f0ec ]
netlink doesn't set any network header offset thus when the skb is
being passed to tap devices via dev_queue_xmit_nit(), it emits klog
false positives due to it being unset like:
...
[ 124.990397] protocol 0000 is buggy, dev nlmon0
[ 124.990411] protocol 0000 is buggy, dev nlmon0
...
So just reset the network header before passing to the device; for
packet sockets that just means nothing will change - mac and net
offset hold the same value just as before.
