====================
pull-request: can 2026-11-03

this is a pull request of 15 patches for net/main.

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

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:

Oliver Hartkopp contributes a patch to convert the unreliable
ARPHRD_CAN type check to the robust can_get_ml_priv(). Further a patch
that adds missing error checking to the bind callback of the CAN
ISO-TP protocol. Followed by converting the CAN RAW, BCM and ISO-TP
protocol to protect the receive lists with a per-device lock. Then the
RAW and ISO-TP protocols are converted to copy the socket options
outside of lock_sock().

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.

ChunYuZhiQiang contributes 2 patches for the CAN netlink interfaces,
to prevent waking up the CAN device, if the interface is down.

The last patch is by Liu Changjie and fixes the decoding of bulk USB
URBs in the Peak USB CAN driver.
