[PATCH net-next 0/11] pull-request: can-next 2026-10-22

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

Hello netdev-team,

this is a pull request of 11 patches for net-next/main and obsoletes
pull-request: linux-can-next-for-7.4-20261021.

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.

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

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

A series by Oliver Hartkopp et al fixes several problems in the CAN
net-layer:

3 patches target the CAN procfs: A patch by Runyu Xiao resets the CAN
pkg_stats using atomics, a patch by Oliver Hartkopp fixes the stats
calculation after a statistics reset. Followed by a patch to remove
kernel pointers from the output.

The last 2 patches are by Oliver Hartkopp as well, they convert the
unreliable ARPHRD_CAN type check to the robust can_get_ml_priv() and
protect the CAN receive lists with a per-device lock.

regards,
Marc
