rtmutex deadlock and memory corruption when running gcc testsuite in next-20260303

rtmutex deadlock and memory corruption when running gcc testsuite in next-20260303

[Bert Karwatzki]

I tried building gcc-14 from the debian repositories (fetched via apt-get 
source gcc-14) on my new and shiny zen5 machine (Cpu: "AMD Ryzen 9 9950X 
16-Core Processor) running debian stable/trixie and linux-next-20260303 
(PREEMPT_RT=y) with the following command:

$ time dpkg-buildpackage --no-sign -B -nc

after about ~1.45h, during the testsuite, the following error happens:

After this error the system does not work properly anymore (htop and ps
don't work anymore, xfce still works, evolution refuses to start and shutting down also hangs) 

I recently successfully compiled gcc-14 from debian on linux-6.18.13, so I'm going to bisect this.
Depending on wether I can single out the offending test this could take a while so I'm
reporting this before the bisection is finished.

As the first splat was a general protection fault, it likely killed the
task from the kernel.

So, the KILL signal likely broke it out of the blocked lock, and I believe
the code treated it as a deadlock:

rt_mutex_slowlock_block() has:

		if (signal_pending_state(state, current)) {
			ret = -EINTR;
			break;
		}

Which would return on SIG_KILL even if in the TASK_UNINTERRUPTABLE state.
Then the code after that has:

	if (likely(!ret)) {
		/* acquired the lock */
		if (build_ww_mutex() && ww_ctx) {
			if (!ww_ctx->is_wait_die)
				__ww_mutex_check_waiters(rtm, ww_ctx, wake_q);
			ww_mutex_lock_acquired(ww, ww_ctx);
		}
		lockevent_inc(rtmutex_slow_acq2);
	} else {
		__set_current_state(TASK_RUNNING);
		remove_waiter(lock, waiter);
		rt_mutex_handle_deadlock(ret, chwalk, lock, waiter);
		lockevent_inc(rtmutex_deadlock);
	}

ret is set to -EINTR so it would enter the else block. And then the
rt_mutex_handle_deadlock() prints that a deadlock was detected.

Thus, I don't think this really has anything to do with rtmutex but has to
do with whatever caused that initial general protection fault.

Re: rtmutex deadlock and memory corruption when running gcc testsuite in next-20260303

[Bert Karwatzki]

I've got no results on the bisection, yet, and this bug is not 100% reproducible:

I did 3 test runs with the gcc-14 source code from debian and:
$ time dpkg-buildpackage --no-sign -b

On the first run I got no error.
On the second run this smaller error happended, but the rest of the system
was not impacted:
