Merge tag 'linux-can-fixes-for-6.1-20221107' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can
Marc Kleine-Budde says: ==================== can 2022-11-07 The first patch is by Chen Zhongjin and adds a missing dev_remove_pack() to the AF_CAN protocol. Zhengchao Shao's patch fixes a potential NULL pointer deref in AF_CAN's can_rx_register(). The next patch is by Oliver Hartkopp and targets the CAN ISO-TP protocol, and fixes the state handling for echo TX processing. Oliver Hartkopp's patch for the j1939 protocol adds a missing initialization of the CAN headers inside outgoing skbs. Another patch by Oliver Hartkopp fixes an out of bounds read in the check for invalid CAN frames in the xmit callback of virtual CAN devices. This touches all non virtual device drivers as we decided to rename the function requiring that netdev_priv points to a struct can_priv. (Note: This patch will create a merge conflict with net-next where the pch_can driver has removed.) The last patch is by Geert Uytterhoeven and adds the missing ECC error checks for the channels 2-7 in the rcar_canfd driver. * tag 'linux-can-fixes-for-6.1-20221107' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: can: rcar_canfd: Add missing ECC error checks for channels 2-7 can: dev: fix skb drop check can: j1939: j1939_send_one(): fix missing CAN header initialization can: isotp: fix tx state handling for echo tx processing can: af_can: fix NULL pointer dereference in can_rx_register() can: af_can: can_exit(): add missing dev_remove_pack() of canxl_packet ==================== Link: https://lore.kernel.org/r/20221107133217.59861-1-mkl@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>
