WARNING: CPU: 0 PID: 91 at kernel/sched/core.c:7253 __might_sleep()
Hi Peter and Steven,
This time the debug patch hits the event_trace_self_tests.

commit 2f85d1824897a3fe2c0d726946f91e0e1f0e0eac
Author: Peter Zijlstra <[email protected]> AuthorDate: Wed Sep 24 10:18:55 2014 +0200 Commit: Peter Zijlstra <[email protected]> CommitDate: Tue Oct 7 19:09:07 2014 +0200
sched: Debug nested sleeps
Validate we call might_sleep() with TASK_RUNNING, which catches places where we nest blocking primitives, eg. mutex usage in a wait loop.
Since all blocking is arranged through task_struct::state, nesting this will cause the inner primitive to set TASK_RUNNING and the outer will thus not block.
Another observed problem is calling a blocking function from schedule()->sched_submit_work()->blk_schedule_flush_plug() which will then destroy the task state for the actual __schedule() call that comes after it.

Steve, wth is that thing supposed to do?
set_current_state(TASK_INTERRUPTIBLE); while (!kthread_should_stop()) schedule();
That looks broken alright. It'll revert to a yield() 'spin' loop if it ever gets a wakeup for anything other than the kthread_stop().
Did you mean to write something like:
set_current_state(TASK_INTERRUPTIBLE);
while (!kthread_should_stop()) {
schedule();
set_current_state(TASK_INTERRUPTIBLE);
}
__set_current_state(TASK_RUNNING);?

Wow, what a blast from the past. That code hasn't been touched since 2009!
Anyway, all that thread did was call test work on each cpu, and then waits to be killed. It should only get a single wake up and that should be from the kthread_stop() call. IOW, that loop should never be executed more than once.
What exactly is the bug here?

The bug is as explained, the loop is wrong and will revert to a yield 'spin' loop after a single wakeup.
The debugging that caught it is that you exit the loop without setting TASK_RUNNING.

I understand that it becomes a yield if something sends a wakeup before killing it. I highly doubt that would ever happen since it doesn't call anything that should wake it up and it only runs at boot up.
Looking at the original email that has the trace, I'm betting it hit the race where kthread_stop() was called on the thread before it set its state to TASK_INTERRUPTIBLE and then the first call to kthread_should_stop() returned true and schedule() was never called and the task exited with the TASK_INTERRUPTIBLE state.
Really no harm here. If we had called set_task_state(TASK_RUNNING) before exiting this never would have been seen.
Anyway, as for a fix, if you want to do it fully with setting TASK_INTERRUPTBILE again in the loop, I'm fine with it. I still don't see any possible way it can be woken up before kthread_should_stop() being true, but hey, lets make it more robust. Then if we ever extend on the tests that are run, which could add a delayed wake up, it would not turn into a yield.

Still we should always assume spurious wakeups, its fragile not to and has so far made life sad a few times.

Right, I'll send the patch. While looking I found another issue, trace_selftest.c:trace_wakeup_test_thread() has a schedule() without a loop around. We should really not do that.

Subject: trace: Robustify wait loop
From: Peter Zijlstra (Intel) <[email protected]>
Date: Wed Oct 8 18:44:26 CEST 2014
The pending nested sleep debugging triggered on the potential stale TASK_INTERRUPTIBLE in this code.
While there, fix the loop such that we won't revert to a while(1) yield() 'spin' loop if we ever get a spurious wakeup.
And fix the actual issue by properly terminating the 'wait' loop by setting TASK_RUNNING.

I'll see if I can get this in this merge window before I leave to Dusseldorf.
BTW, what do you think of this solution? Feel free to ack it if you like it.
