Crash with chromium ozone #2056

travankor · 2020-03-03T10:17:57Z

I am using sway 1.4 with wlroots 0.10.0 and I notice that wlroots crashes when chromium (v80) ozone creates too many popups.

The issue can be reproduced by creating nested bookmarks (ie: bookmark folders inside the bookmarks toolbar) and then navigating to the nested bookmark and clicking on the bookmark. This bug is not 100% reproducible (sometimes chromium will crash and sway will still work). Chromium will be running in the background after sway crashes.

Here is the debug log of sway when it crashes (using a vanilla config).

Stacktrace is here.

wlroots has migrated to gitlab.freedesktop.org. This issue has been moved to:

It'll be very hard to understand what's going on without a stack trace.

travankor · 2020-03-03T10:25:07Z

Any idea why it's not being created?

emersion · 2020-03-03T10:26:24Z

No, sorry. Attaching with GDB via SSH may be a workaround.

emersion · 2020-03-03T10:26:56Z

Or just running Sway in GDB in Sway, since it's not DRM-related.

Here's a trace.

Seems like it hits this assert:

Just hit the WLR_XDG_SURFACE_ROLE_NONE false assert with Firefox. The surface->role is xdg_popup. Maybe this is related to popup destruction or something..?

valpackett · 2020-07-03T21:19:43Z

Or, wait, this is weird — there is a couple of early returns in between wlr_surface_set_role(xdg_surface->surface, &xdg_popup_surface_role…) and xdg_surface->role = WLR_XDG_SURFACE_ROLE_POPUP!

I'm especially not sure about the "xdg-surface has already been constructed" one. That check looks like it should happen before everything else. The other ones are wl_resource_post_no_memory so that object would be dead.

Hopefully fixes swaywm#2056

Hopefully fixes #2056

emersion · 2020-07-04T10:11:55Z

A fix has been merged to send a protocol error instead of dying on an assert.

valpackett · 2020-07-04T11:10:03Z

A fix has been merged to send a protocol error instead of dying on an assert.

???

#2318 hopefully fixes the root cause; #2057, which does the protocol error thing, has not been merged.

emersion · 2020-07-04T11:15:46Z

Hm, looking at it again, #2318 just swaps two function calls that send protocol errors. So it should have zero impact, shouldn't have merged it?

valpackett · 2020-07-04T11:24:19Z

Does wlr_surface_set_role send protocol errors?

My thinking was, in the original code it could be that wlr_surface_set_role successfully sets the xdg_popup_surface_role, then xdg_surface->role != WLR_XDG_SURFACE_ROLE_NONE does the protocol error and early return, the client ignores the protocol error or something (???) and somehow the surface is committed again

progandy · 2020-07-04T12:23:10Z

Does wlr_surface_set_role send protocol errors?

Yes.

wlroots/types/wlr_surface.c

Line 712 in 58df3ed

if (surface->role != NULL && surface->role != role) {

Former behaviour:

wlr_surface role is set and role is not popup (e.g. toplevel) -> XDG_WM_BASE_ERROR_ROLE
wlr_surface role_data is set and role_data is not the same popup implementation -> XDG_WM_BASE_ERROR_ROLE
xdg_surface role is set -> XDG_SURFACE_ERROR_ALREADY_CONSTRUCTED

New behaviour after #2318

xdg_surface role is set to any role, -> XDG_SURFACE_ERROR_ALREADY_CONSTRUCTED
xdg_surface role is not set, but wlr_surface role is set see first two steps above. (Can that happen?)

I confirm that this bug is still reproducible on wlroots-9feeb27 and sway-6991ac8.

../types/xdg_shell/wlr_xdg_toplevel.c:182:24: runtime error: member access within null pointer of type 'struct wlr_xdg_toplevel'

emersion · 2020-08-24T07:29:42Z

Weird, it seems like xdg_surface->role is set to TOPLEVEL but xdg_surface->toplevel is NULL. I don't understand how this can happen because both are always set together.

travankor · 2020-08-25T05:56:11Z

Wait, so is this bug related to the linked issues?

I can reproduce this crash with pcmanfm 0.15.1 and QT 5.15.0. The crash sometimes happens when pcmanfm creates a popup when you hover over icons.

The backtrace is the same as the originally reported backtrace, but I can post it again.
