Description Alexander Larsson 2021-04-14 08:47:49 UTC 
I'm running F34 (xorg-x11-server-Xwayland-21.1.0-1.fc34.x86_64), and when I open the xterm context menu (ctrl-middle-click on xterm window) the Xwayland server dies. I'm using the nvdidia driver on top of the wayland gnome-shell.

Here is the crash:

Comment 2 Olivier Fourdan 2021-04-14 09:14:09 UTC 
This is not actually a crash but rather an Wayland error which leads to an abort (Wayland errors are always fatal):

#5  0x000055ff255fbf40 in xwl_log_handler (format=<optimized out>, args=<optimized out>) at ../hw/xwayland/xwayland.c:238
#6  0x00007ffb1cd60cca in wl_log (fmt=fmt@entry=0x7ffb1cd6629f "%s@%u: error %d: %s\n") at ../src/wayland-util.c:404
#7  0x00007ffb1cd611cb in display_handle_error (data=<optimized out>, display=0x55ff26349950, object=0x55ff26c10ce0, code=2, message=<optimized out>) at ../src/wayland-client.c:911

So that backtrace (and the retrace) are pretty much useless I'm afraid (other that telling this is a Wayland protocol error).

I would instead prefer to see the journalctl logs at the time of the abort (Xwayland messages should shows up as "gnome-shell", because gnome-shell spawns Xwayland), that should show the actual message posted by that wl_log() there.

Also, as stated (and as seen in the backtrace) you're using the NVidia closed source driver and hence the EGLStrem backend, is that reproducible with the GBM backend with open source drivers as well? Reason I ask is because I cannot reproduce here (and I use xterm quite often).
Comment 3 Alexander Larsson 2021-04-14 09:29:31 UTC 
Before the crash:

I've not tried with the GBM backend, but could not reproduce on my intel laptop. That, combined with the above seems to say that this is some form of nvidia driver issue.
Comment 4 Alexander Larsson 2021-04-14 09:32:50 UTC 
For the record, this is nvidia kernel driver version:

NVRM version: NVIDIA UNIX x86_64 Kernel Module  460.67  Thu Mar 11 00:11:45 UTC 2021
GCC version:  gcc version 11.0.1 20210405 (Red Hat 11.0.1-0) (GCC)

Nevermind, this is a dupe of bug 1943936

Would you be willing to test some more test builds for me, which would log debugging statements? (I do not have any nvidia hardware at hand here)
Comment 6 Alexander Larsson 2021-04-14 09:37:08 UTC 
Sure, just point me at them and I'll try them.
Comment 7 Olivier Fourdan 2021-04-14 13:11:29 UTC 
FTR, what happens here is that when we get to use the EGLStream, the stream is not in a valid state anymore, it got disconnected.

But I do not know yet why that is, which part gets the stream disconnected (Xwayland itself, the Wayland compositor or maybe some other issue in EGLStream), so the build here is mostly to log what is going on, it won't fix anything:

https://koji.fedoraproject.org/koji/taskinfo?taskID=65915941

The idea would be for you to install that build, reproduce the issue and post the content of journalctl which hopefully might give some hint of what is going on (eg. if this is Xwayland itself closing the stream by mistake).

TIA!
Comment 8 Alexander Larsson 2021-04-14 13:25:27 UTC 
So, with that rpm I don't get a crash, but when i update I get:

Can you please give this build a try:

and post the logs?

at this point gnome-shell is locked up and just shows black (but the machine lives fine via a remote login).
Comment 13 Olivier Fourdan 2021-04-15 07:06:20 UTC 
Oh, I know it may sound surprising, but I believe we're on the right track here, only if I was paying more attention…

FTR, we want to keep the EGLStream around until it's released by the compositor, even when the X11 window content changes which invalidates the window pixmap.

That part was (mistakenly, I reckon) dropped with a patch in master/xwayland-21.x and I reason to believe this is the root cause of the issue here, so my fix is to increase the refcount on the pixmap so it's kept around along with the EGLStream until released.

But the logs clearly show the problem with my fix:

eglstream: xwl_eglstream_queue_pending_stream: win 0x800055 begins new eglstream for pixmap=0x55602b87bc90/xwl_pixmap=0x55602b86f5a0
eglstream: xwl_eglstream_set_window_pixmap: win 0x800055 changes, pixmap=0x55602b883010/xwl_pixmap=0x55602b86f5a0 now invalid
eglstream: xwl_glamor_eglstream_destroy_pixmap: pixmap=0x55602b87bc90/xwl_pixmap=0x55602b86f5a0 refcnt=1

Notice how the xwl_pixmap is the same but the pixmap is different? That's because my patch increases the refcount on the pixmap in xwl_eglstream_set_window_pixmap() but that pixmap there is the *new* one, whereas we want to keep a reference on the *old* one, so it increases the refcount on the wrong pixmap there <facepalm>. That explains why the pixmaps show high values in refcount (hence leaks) but the issue still occurs, well, because the old pixmap is still discarded too early.

So, ahummm, long story short, mind giving this new build a try…?

(and also provide the logs, well, as usual).

Comment 15 Alexander Larsson 2021-04-15 07:32:24 UTC 
It would be awesome if we had a printf debugging helper that converted %p into "<ptr n>" or something where n was an incrementing number unique to that particular pointer value out of the set that was ever printed... Would make logs more reproducible/diffable and easier to spot issues like this.
Comment 16 Alexander Larsson 2021-04-15 07:34:33 UTC 
FTR, this latest version also makes emacs-x11 crash Xwayland on startup, in a similar way to the above.
Comment 17 Olivier Fourdan 2021-04-15 07:51:58 UTC 
sigh, I actually had hopes in that one…
Comment 18 Olivier Fourdan 2021-04-15 09:36:17 UTC 
Can you please give this build a try:

Comment 20 Alexander Larsson 2021-04-15 10:58:17 UTC 
Just for fun I made a unique pointer printf formatter:

https://gist.github.com/alexlarsson/e50260525b866d54896a2fbc57aad6e8

Just call unique_pointer_printf_init() and use %P as formater to g_print/printf (assumes glibc printf).
Comment 21 Alexander Larsson 2021-04-15 10:59:49 UTC 
IE:
  printf ("p: '%-20p' '%20p' %p\n", &a, &b, &c);
  printf ("P: '%-20P' '%20P' %P\n", &a, &b, &c);
  printf ("P: '%-20P' '%20P' %P\n", &a, &b, &c);

Prints:

p: '0x7ffea11ec40f      ' '      0x7ffea11ec40e' 0x7ffea11ec40d
P: '0u1                 ' '                 0u2' 0u3

Actually not true. I get a context menu, but its not rendered. I can ctrl-right-drag-release and change the font size. I just have to do it blindly, because nothing changes on the screen.

eglstream: xwl_glamor_eglstream_remove_pending: removing stream for xwl_pixmap=0x56208a64f2f0
eglstream: xwl_eglstream_destroy_pixmap_stream: destroying stream for xwl_pixmap=0x56208a64f2f0

…works as intended, the window pixmap got changed before we had a chance to use the stream, the pixmap and the stream are kept until released, where it eventually gets all destroyed, no fuss, no more drama.

And then that occurs:

EGLStream: Framebuffer incomplete 0x8219, not posting damage
glamor: Failed to post damage

0x8219 is GL_FRAMEBUFFER_UNDEFINED.

We're not posting damage, so no wonder the window doesn't show anything.
Comment 28 Olivier Fourdan 2021-04-15 15:00:59 UTC 
Right, the reason for this is quite obvious, actually.

To tell whether it can post damage, xwayland uses the xwl_glamor_eglstream_post_damage() which will look for an existing pending and its validity, and return TRUE (ie. it is OK to post damage) if there is an xwl_pixmap and there is no pending for it.

Now, that logic hasn't changed. But we have not tied the xwl_pixmap with the x11 pixmap.

Anyway, mind giving this new build a try:

https://koji.fedoraproject.org/koji/taskinfo?taskID=65998416

Note it may break completely, get you a complete black screen, or worse... (I know, that sounds very encouraging).
Comment 29 Alexander Larsson 2021-04-15 15:46:58 UTC 
It kinda works, but the damage tracking still seem off. The inital menu shows up completely. However, once i start navigating the menu it starts flickering badly, sometimes not updating the region.

Like so: https://share.icloud.com/photos/0ToLZ8aya4USI71HsQeGE6IEw

Comment 30 Olivier Fourdan 2021-04-16 09:27:35 UTC 
Right I think all our trouble here come from the removal of the separate ref counter for the EGLStream xwl_pixmap.

Previously, we would have pending streams associated with top level X11 windows, keeping temporary accounting for the pending streams before they get fully initialized for the xwl_pixmap which would be associated with X11 pixmaps.

If the window content changes before the stream is ready, the corresponding pending stream would be marked as invalid and the pending stream would be eventually removed once the stream becomes ready.

Since commit affc47452 - "xwayland: Drop the separate refcount for the xwl_pixmap", we no longer keep a separate reference counter for the xwl_pixmap, but rather tie it to the X11 pixmap lifespan. Yet, the pending stream would still be associated with the X11 toplevel window and I think this is what is causing confusion.

I think we should instead just tie the xwl_pixmap with the pixmap, and the pending stream with the xwl_pixmap. That sounds more logical, now that we don't keep a separate refcounting for the xwl_pixmap.

Alex, if I may, would you mind giving this new build a try:

https://koji.fedoraproject.org/koji/taskinfo?taskID=66052822

(Note, if that still fails, I'll probably have to wait for the hardware here, I mean, debugging without being able to test myself does not really scale, I think this is fairly complex as it is).

Yikes, my bad, the current (old) pixmap on a window is NULL at first.

Hopefully this one should go a bit farther:

No crashes now, but it still gets wrong damage for the context menu, and also now for the main window.

Comment 36 Olivier Fourdan 2021-04-16 15:03:05 UTC 
Humm, sad, it's a shame that it does not work, the logs look very sensible to me now!

I'll have to wait for the hardware to complete the fix I'm afraid, thanks a lot for your help!
Comment 37 Alexander Larsson 2021-04-19 06:24:29 UTC 
Well, this is vastly better than an XWayland crash.
Comment 38 Olivier Fourdan 2021-04-19 13:46:39 UTC 
Would that new build help with the visual glitches seen in the xterm menu:

  https://koji.fedoraproject.org/koji/taskinfo?taskID=66260063

A word of caution though, I changed the code once again, so it may very well break in new and creative ways.

My goal is to get back to the same level that we were with Xwayland in the stable server-1.20-branch (i.e. Xwayland does not crash and damages are not not completely off target as with the video from comment 29).
Comment 39 Alexander Larsson 2021-04-19 14:47:29 UTC 
-16 is similarly broken with glitches in the menu, but additionally it crashes when closing the menu:

Comment 40 Olivier Fourdan 2021-04-21 09:14:50 UTC 
(In reply to Alexander Larsson from comment #39)
> -16 is similarly broken with glitches in the menu,

OK, that's very interesting, it would mean that the glitches are not related to the changes I introduced to fix the original crash. That's very interesting.

So based on that, let's take another approach, back to the logic from -15 (the one which did not crash and where the logs seemed sound) and add some more logs to show which area we damage and from which pixmap/xwl_pixmap/wl_buffer, hopefully that'll shed some light on why you see the glitches.

https://koji.fedoraproject.org/koji/taskinfo?taskID=66397726

(Please note this is a new release 21.1.1 as the package has now reached stable)

The idea would be for you to install that test package, and redo the test with the xterm menu and post the corresponding logs (well, basically, as usual).
Comment 41 Alexander Larsson 2021-04-21 11:23:05 UTC 
Here is just poping up the context menu, slowly mouse down and then release. It looks similarly to the previous video. I.e. some repaints are ok, but many seem completely missing or wrong.

Comment 42 Alexander Larsson 2021-04-21 11:26:36 UTC 
It looks to me like the posted damage regions are correct, but they just don't get repainted.
Comment 43 Alexander Larsson 2021-04-21 11:32:17 UTC 
For the record, i have a dual monitor setup with the left monitor rotated and both at 200% scale, however disabling the scale and using just one monitor i got the same menu flickering.
Comment 44 Alexander Larsson 2021-04-21 11:42:50 UTC 
Its interesting how it seems to be reproducible.

The first three damages in the log are ok. They are: 1 paint everything, 2 highlight first item, 3 unhighlight first item & highlight second.
But the third is completely broken, instead of unhighlighting item 2 and highlighting item 3 it just render the area of item 2 & 3 completely white.

This happens *every* time. Additionally, if instead of mousing from 1->2->3 I go 1->2->1 then item 1&2 go white. Or if i go item 1-> menu header -> item 1, then item 1 goes white. 

Its like if the third damage event always goes wrong...
Comment 45 Alexander Larsson 2021-04-21 11:56:34 UTC 
I can reproduce also by running "xdvi" and triggering damage events by typing in the path entry that is focused on window open. The first two keys i press are ok, but then the whole window starts getting partially transparent differently for each new key i press.
Comment 46 Olivier Fourdan 2021-04-21 12:50:22 UTC 
I see, as if it was using freed data, except that I don't see it reusing freed pixmaps in the logs.

Can you please retry with that text build, it also logs the callback and the stream, maybe it gets confused with those…

Comment 47 Alexander Larsson 2021-04-21 13:37:44 UTC 
Not a lot different:
Is there a way for me to manually run an Xwayland so i can valgrind it?

Comment 48 Olivier Fourdan 2021-04-21 14:01:16 UTC 
Could you please post a bit more of the logs? I'd like to match the pending stream queue, invalidation, until callback gets eventually triggered.

For running Xwayland within valgrind, best is to prepare a script that does exactly that:

1. Rename the current "Xwayland" binary to "Xwayland.bin"

    cp /usr/bin/Xwayland /usr/bin/Xwayland.bin

2. And then replace the Xwayland binary with a script that run valgrind, e.g.:

    exec valgrind --track-origins=yes --log-file=xwayland.%p /usr/bin/Xwayland.bin "$@"

Comment 51 Olivier Fourdan 2021-04-21 15:09:53 UTC 
Yikes! I must be missing something, the logs look just fine to me :/
Comment 52 Olivier Fourdan 2021-04-21 15:55:41 UTC 
I wonder if that could be on the compositor side maybe…
Comment 53 Olivier Fourdan 2021-04-22 09:41:08 UTC 
Haha! So I asked Jonas if he could run some more tests for me.

So far, I reckoned those glitches were a regression in Xwayland 21.1 or possibly in mutter, so I asked Jonas if he could test Xwayland 21.1 with mutter 3.38, but it's the same, so that rules out a regression in mutter.

Then Jonas tried Xwayland from 1.20 with mutter 3.38 and the result is… actually worse.

So that means that those glitches are not a regression, and probably not directly related to the crash, meaning that the patches which fix the crash are probably good enough!

Hi Alex, mind giving this last build a try:

https://koji.fedoraproject.org/koji/taskinfo?taskID=66794294

This is just to make sure the latest set of patches I posted in https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/646 do not regress any further wrt. the initial issue (i.e. it won't address the visual glitches, but it should not crash anymore).

Nevermind, I received the hardware and did the test.
Comment 56 Olivier Fourdan 2021-05-03 12:59:14 UTC 
This test build should fix the crash and help with rendering issues:
