Subject: [PATCH net 0/3] pull-request: can 2024-02-14

Hello netdev-team,

this is a pull request of 3 patches for net/master.

the first patch is by Ziqi Zhao and targets the CAN J1939 protocol, it
fixes a potential deadlock by replacing the spinlock by an rwlock.

Oleksij Rempel's patch adds a missing spin_lock_bh() to prevent a
potential Use-After-Free in the CAN J1939's
setsockopt(SO_J1939_FILTER).

Maxime Jayat contributes a patch to fix the transceiver delay
compensation (TDCO) calculation, which is needed for higher CAN-FD bit
rates (usually 2Mbit/s).

regards,
Marc
