Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ksmbd: fix WARNING "do not call blocking ops when !TASK_RUNNING"<br /> <br /> wait_event_timeout() will set the state of the current<br /> task to TASK_UNINTERRUPTIBLE, before doing the condition check. This<br /> means that ksmbd_durable_scavenger_alive() will try to acquire the mutex<br /> while already in a sleeping state. The scheduler warns us by giving<br /> the following warning:<br /> <br /> do not call blocking ops when !TASK_RUNNING; state=2 set at<br /> [] prepare_to_wait_event+0x9f/0x6c0<br /> WARNING: CPU: 2 PID: 4147 at kernel/sched/core.c:10099 __might_sleep+0x12f/0x160<br /> <br /> mutex lock is not needed in ksmbd_durable_scavenger_alive().
