Please:
 - add some RT developers on Cc:
 - add lkml
 - use [PATCH RT] instead just [PATCH] so it is visible that you target
   the RT tree.

So you are saying:
	T0			T1			    T2
	wait_for_completion()
	 do_wait_for_common()
	  __prepare_to_swait()
	   schedule()
	    		       complete()
			        x->done++ (0 -> 1)
				raw_spin_lock_irqsave()
				 swake_up_locked()           wait_for_completion()
				  wake_up_process(T0)
				  list_del_init()
				raw_spin_unlock_irqrestore()
	                                                      raw_spin_lock_irq(&x->wait.lock)
	 raw_spin_lock_irq(&x->wait.lock)                      x->done != UINT_MAX, 1 -> 0
							       return 1
							      raw_spin_unlock_irq(&x->wait.lock)
	 while (!x->done && timeout),
	 continue loop, not enqueued
	 on &x->wait

The difference compared to the non-swait based implementation is that
swake_up_locked() removes woken up tasks from the list while the other
implementation (wait_queue_entry based, default_wake_function()) does
not. Buh

One question for the upstream completion implementation:
completion_done() returns true if there are no waiters. It acquires the
wait.lock to ensure that complete()/complete_all() is done. However,
once complete releases the lock it is guaranteed that the wake_up() (for
the waiter) occurred. The waiter task still needs to be remove itself
from the wait-queue before the completion can be removed.
Do I miss something?

you can keep DECLARE_SWAITQUEUE remove just __prepare_to_swait()

Yes, exactly.  I was wondering if swait could be changed to not remove
the waiter, but that seemed like a bad idea.  It is an unusual semantic,
though.

I thought some more about this, wondering why everything isn't keeling
over because of this.  I'm guessing that just about everything using
completions has a single waiter, so it doesn't matter.  I just wrote
some code that has a bunch of waiters, so I hit it.

Now.. that will fix it, but I think it is also wrong.

The problem being that it violates FIFO, something that might be more
important on -RT than elsewhere.

The regular wait API seems confused/inconsistent when it uses
autoremove_wake_function and default_wake_function, which doesn't help,
but we can easily support this with swait -- the problematic thing is
the custom wake functions, we musn't do that.

(also, mingo went and renamed a whole bunch of wait_* crap and didn't do
the same to swait_ so now its named all different :/)

Something like the below perhaps.

Wouldn't -RT be more about waking the task with the highest priority
instead the one that waited the longest?

This still violates FIFO because a task can do wait_for_completion(),
not enqueue itself on the list because it noticed a pending wake and
leave. The list order is preserved, we have that.
But this a completion list. We have probably multiple worker waiting for
something to do so all of those should be of equal priority, maybe one
for each core or so. So it shouldn't matter which one we wake up.

Corey, would it make any change which waiter is going to be woken up?

Possibly, but that's a far larger patch. Also, even with that
completions do not avoid inversions and thus don't really make nice RT
primitives anyway.

In the application that found this, the wake order probably isn't
relevant.

For other applications, I really doubt that very many are using multiple
waiters.  If so, this bug would have been reported sooner, I think.

As you mention, for RT you would want waiter woken by priority and FIFO
within priority.  I don't think POSIX says anything about FIFO within
priority, but that's probably a good idea.  That's no longer a simple
wait queue  The way it is now is probably closer to that than what Peter
suggested, but not really that close.

This is heavily used in drivers and fs code, where it probably doesn't
matter.  I looked through a few users in mm and kernel, and they had
one waiter or were init/shutdown type things where order is not important.

So I'm not sure it's important.

See. So it does not really matter if a particular waiter ends up at the
end of the queue.
Anyway, I don't really think we need this but if you want it, let me add
it.
What about the other question I had regarding completion_done()?

most other do either one waiter/waker pair or one waker and multiple
waiter. And then reinit_completion() is used for the next round.

Why did you bring POSIX into this? This isn't an API exported to
userland which would fall into that category.

Peter's suggestion for FIFO is that we probably don't want to starve one
thread/waiter if it is always enqueued at the end of the list. As you
said, in your case it does not matter because (I assume) each waiter is
equal and the outcome would be the same.

My understanding is that POSIX.1b scheduling classes affect everything.
So if you have two processes blocked on the same things for any reason,
you need to wake up the higher priority one first.  In reality, it
probably doesn't matter unless something more critical uses completions.

Yeah, my case is not relevant to this, I'm more concerned with the cases
that are.

So you mean:

	init_completion(&done);


	wait_for_copmletion(&done)
	  spin_lock()
	   __add_wait_queue()
	  spin_unlock()
	  schedule()

					complete()
								completion_done()
	  spin_lock()
	  __remove_wait_queue()
	  spin_unlock()

Right?

I think that boils down to that whenever you have multiple waiters,
someone needs to be in charge of @done's lifetime.

The case that matters is:

	DECLARE_COMPLETION_ONSTACK(done)

	while (!completion_done(&done))
		cpu_relax();

Where there is but a single waiter, and that waiter is
completion_done(). In that case it must not return early.

Now, I've also seen a ton of code do:

	if (!completion_done(done))
		complete(done);

And that makes me itch... but I've not bothered to look into it hard
enough.

The commit 90e1b18eba2ae4a729 is delta of reverting your patch and
adding Peter's patch instead. If you look into the queue
  https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git/diff/patches/swait-Delete-the-task-from-after-a-wakeup-occured.patch?h=linux-5.0.y-rt-patches&id=8ef6644ae2ac8fc18f157c3deb70fa9acb95a486

is what Peter suggested in the thread and this
  https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git/diff/patches/sched-completion-Fix-a-lockup-in-wait_for_completion.patch?h=linux-5.0.y-rt-patches&id=8ef6644ae2ac8fc18f157c3deb70fa9acb95a486

is the removal.

Just to avoid confusion... it wasn't my patch 1921ea799b7dc56
(sched/completion: Fix a lockup in wait_for_completion()) that caused
the issue, nor was it Peter's version of it.  Instead, it was the patch
mentioned above, 90e1b18eba2ae4a729 ("swait: Delete the task from after a
wakeup occured"), which came from someone else.  I can verify by visual
inspection that that patch is broken and it should definitely be removed.
Just don't want someone to be confused and remove the wrong patch.

Okay. So the original Corey fix as in v5.0.14-rt9 works for everyone.
Peter's version as I picked it up for v5.0.21-rt14 is causing problems
for two persons now.

I'm leaning towards reverting it back to old version for now…

I'm having the same problem on a Cyclone V based ARM board. Reverting
this commit solves the boot issue for me as well.

Yeah.  d_wait_lookup() does not use __SWAITQUEUE_INITIALIZER() to
intitialize it's queue item, but uses swake_up_all(), so it goes
into an infinite loop since it won't remove the item because remove
isn't set.

I'd suspect there are other places this is the case.

In fact, my system doesn't boot with this commit in 5.0-rt.

If I revert 90e1b18eba2ae4a729 ("swait: Delete the task from after a
wakeup occured") the machine boots again.

Sebastian, I think that's a bad commit, please revert it.

Thanks!

No, I did reply to the right email, but it wasn't the top patch I was
having issues with. It was the patch I replied to:

This change below that Sebastian marked as stable-rt is what is causing
me an issue. Not the patch that started the thread.

Bah, I'm replying to the wrong commit that I'm having issues with.

I searched your name to find the patch that is of trouble, and picked
this one.

I'll go find the problem patch, sorry for the noise on this one.

I show that patch is already applied at

    1921ea799b7dc561c97185538100271d88ee47db
    sched/completion: Fix a lockup in wait_for_completion()

git describe --contains 1921ea799b7dc561c97185538100271d88ee47db
v4.19.37-rt20~1

So I'm not sure what is going on.

Yes, it wont boot. There is no testcase as I don't even make it to a
boot prompt. I applied the patch and it crashes, I remove the patch and
it boots without issue.

Attached is the full dmesg and the config used. I applied it to

  ae97a0ba0197fb424008a317b79bebacd6a50213
  Linux 4.19.56-rt23

It works fine for 5.0.14-rt9 where it was added.

Thanks a bunch.  Do I need to do anything for backports?  I'm pretty
sure this goes back to 4.4.

From: Corey Minyard <cminyard@mvista.com>

The function call do_wait_for_common() has a race condition that
can result in lockups waiting for completions.  Adding the thread
to (and removing the thread from) the wait queue for the completion
is done outside the do loop in that function.  However, if the thread
is woken up, the swake_up_locked() function will delete the entry
from the wait queue.  If that happens and another thread sneaks
in and decrements the done count in the completion to zero, the
loop will go around again, but the thread will no longer be in the
wait queue, so there is no way to wake it up.

Visually, here's a diagram from Sebastian Andrzej Siewior:
  T0                    T1                       T2
  wait_for_completion()
   do_wait_for_common()
    __prepare_to_swait()
     schedule()
                        complete()
                         x->done++ (0 -> 1)
                         raw_spin_lock_irqsave()
                         swake_up_locked()       wait_for_completion()
                          wake_up_process(T0)
                          list_del_init()
                         raw_spin_unlock_irqrestore()
                                                  raw_spin_lock_irq(&x->wait.lock)
  raw_spin_lock_irq(&x->wait.lock)                x->done != UINT_MAX, 1 -> 0
                                                  raw_spin_unlock_irq(&x->wait.lock)
                                                  return 1
   while (!x->done && timeout),
   continue loop, not enqueued
   on &x->wait

Basically, the problem is that the original wait queues used in
completions did not remove the item from the queue in the wakeup
function, but swake_up_locked() does.

Fix it by adding the thread to the wait queue inside the do loop.
The design of swait detects if it is already in the list and doesn't
do the list add again.

Changes since v1:
* Only move __prepare_to_swait() into the loop.  __prepare_to_swait()
  handles if called when already in the list, and of course
  __finish_swait() handles if the item is not queued on the
  list.
