Subject: [PATCH 5.4 02/13] net: qrtr: Fix port ID for control messages
Date: Mon, 22 Feb 2021 13:13:19 +0100	[thread overview]
Message-ID: <20210222121017.137917943@linuxfoundation.org> (raw)
In-Reply-To: <20210222121013.583922436@linuxfoundation.org>

From: Loic Poulain <loic.poulain@linaro.org>

[ Upstream commit ae068f561baa003d260475c3e441ca454b186726 ]

The port ID for control messages was uncorrectly set with broadcast
node ID value, causing message to be dropped on remote side since
not passing packet filtering (cb->dst_port != QRTR_PORT_CTRL).

Fixes: d27e77a3de28 ("net: qrtr: Reset the node and port ID of broadcast messages")
