====================
pull-request: can 2021-06-19

this is a pull request of 5 patches for net/master.

The first patch is by Thadeu Lima de Souza Cascardo and fixes a
potential use-after-free in the CAN broadcast manager socket, by
delaying the release of struct bcm_op after synchronize_rcu().

Oliver Hartkopp's patch fixes a similar potential user-after-free in
the CAN gateway socket by synchronizing RCU operations before removing
gw job entry.

Another patch by Oliver Hartkopp fixes a potential use-after-free in
the ISOTP socket by omitting unintended hrtimer restarts on socket
release.

Oleksij Rempel's patch for the j1939 socket fixes a potential
use-after-free by setting the SOCK_RCU_FREE flag on the socket.

The last patch is by Pavel Skripkin and fixes a use-after-free in the
ems_usb CAN driver.

All patches are intended for stable and have stable@v.k.o on Cc.
