Zhang Changzhong 875609ad80 can: j1939: j1939_can_recv(): ignore messages with invalid source address ... commit a79305e156 upstream. According to SAE-J1939-82 2015 (A.3.6 Row 2), a receiver should never send TP.CM_CTS to the global address, so we can add a check in j1939_can_recv() to drop messages with invalid source address. Fixes: 9d71dd0c70 ("can: add support of SAE J1939 protocol") Link: https://lore.kernel.org/all/1635431907-15617-3-git-send-email-zhangchangzhong@huawei.com Cc: stable@vger.kernel.org Signed-off-by: Zhang Changzhong <zhangchangzhong@huawei.com> Acked-by: Oleksij Rempel <o.rempel@pengutronix.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-11-18 14:03:48 +01:00
