ksmbd: fix listener task lifetime on netdev events
Get instant alerts when new vulnerabilities affect Linux - before attackers find them.
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix listener task lifetime on netdev events The listener thread exits when its listening socket is shutdown. The netdevice notifier shuts down the socket before calling kthread_stop(), so the task_struct can be freed before kthread_stop() gets its reference. Create the listener in a stopped state and hold an extra task_struct reference until kthread_stop_put() completes. Also stop and release listeners before freeing their interface records during TCP teardown.
