Subject: [PATCH net 0/4] pull-request: can 2023-04-05

Hello netdev-team,

this is a pull request of 4 patches for net/master.

The first patch is by Oleksij Rempel and fixes a out-of-bounds memory
access in the j1939 protocol.

The remaining 3 patches target the ISOTP protocol. Oliver Hartkopp
fixes the ISOTP protocol to pass information about dropped PDUs to the
user space via control messages. Michal Sojka's patch fixes poll() to
not forward false EPOLLOUT events. And Oliver Hartkopp fixes a race
condition between isotp_sendsmg() and isotp_release().

regards,
Marc
