[PATCH net-next 0/12] pull-request: can-next 2026-10-18

[Marc Kleine-Budde <mkl@pengutronix.de>]

Hello netdev-team,

this is a pull request of 12 patches for net-next/main.

The first patch is by Vincent Mailhol and drops CAN-XL frames on non
CAN-XL devices.

A patch by Sang-Heon Jeon removes a redundant NULL check before
netdev_hold() in the CAN RAW protocol.

Oliver Hartkopp's patch converts the unreliable ARPHRD_CAN type check
to the robust can_get_ml_priv().

A patch by Runyu Xiao for CAN proc resets the pkg_stats using atomics
individually. Oliver Hartkopp also contributes a patch for the CAN
proc to remove kernel pointers from the output.

A patch by Kaixuan Li for the CAN ISOTP protocol improves the check
for the correct CAN CC/FD frames.

Oliver Hartkopp series targets the CAN isotp, bcm and raw protocols
and fixes a use-after-free in the in isotp and bcm and converts the
raw protocol to the same locking scheme.

The next 3 patches are by Cunhao Lu and make CAN skb freeing safe in
any context in several CAN helper functions.

regards,
Marc
