Subject: Task exit via rt_task_suspend()?
Date: Fri, 18 Aug 2023 11:28:29 +0200	[thread overview]
Message-ID: <48358551.MN2xkq1pzW@somecomputer> (raw)

Hi!

I have a not yet understood deadlock in a Xenomai application on my desk.
It looks like the deadlock is caused by the fact that rt_task_suspend()
can cause the calling thread to exit.

So, a thread puts itself into suspend and never returns (and exists).
Debugging indicates that ret = __RT(kill(pid, SIGSUSP)); in threadobj_suspend()
is the place where it enters the kernel and never return and inside the
kernel exits.

Can this be? :-S

Thanks,
//richard
