Zhang Changzhong 24d8a24f56 can: j1939: j1939_tp_cmd_recv(): check the dst address of TP.CM_BAM ... commit 164051a6ab upstream. The TP.CM_BAM message must be sent to the global address [1], so add a check to drop TP.CM_BAM sent to a non-global address. Without this patch, the receiver will treat the following packets as normal RTS/CTS transport: 18EC0102#20090002FF002301 18EB0102#0100000000000000 18EB0102#020000FFFFFFFFFF [1] SAE-J1939-82 2015 A.3.3 Row 1. Fixes: 9d71dd0c70 ("can: add support of SAE J1939 protocol") Link: https://lore.kernel.org/all/1635431907-15617-4-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 19:16:03 +01:00
