- Summary
- ksmbd: fix WARNING "do not call blocking ops when !TASK_RUNNING"
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix WARNING "do not call blocking ops when !TASK_RUNNING"
waiteventtimeout() will set the state of the current task to TASKUNINTERRUPTIBLE, before doing the condition check. This means that ksmbddurablescavengeralive() will try to acquire the mutex while already in a sleeping state. The scheduler warns us by giving the following warning:
do not call blocking ops when !TASKRUNNING; state=2 set at [<0000000061515a6f>] preparetowaitevent+0x9f/0x6c0 WARNING: CPU: 2 PID: 4147 at kernel/sched/core.c:10099 _mightsleep+0x12f/0x160
mutex lock is not needed in ksmbddurablescavenger_alive().
