Description Matt Fagnani 2019-06-08 21:28:05 UTC
Description of problem:

I booted the F30 KDE Plasma spin, and I logged into Plasma 5.15.5 on Wayland from sddm 0.18.1. I installed the firefox-wayland-67.0-4 rpm. I added the Firefox on Wayland icon from the menu to the desktop. I ran Firefox on Wayland. Firefox on Wayland was frequently unresponsive. I loaded the Troubleshooting information screen. I closed Firefox. coredumpctl showed segmentation faults of Firefox 4 of 4 times after I closed it. abrt ran gdb on the core dump, and gdb used about 6-7 GB of memory. I logged out of Plasma and stopped sddm and other processes. gdb didn't finish after 1.5 hours so I stopped it. When I ran coredumpctl debug on the core dumps, gdb used about 7 GB of ram. I haven't been able to get a trace in gdb yet for those reasons. I've installed the firefox, glibc, glib2, nspr, mesa, pulseaudio debug rpms for the programs in the traces. The traces shown by coredumpctl info were all like the following:

Process 5098 (firefox) of user 1000 dumped core.

I suspect the segmentation faults involved the shutdown terminator thread because audit messages like the following were shown in the journal after each crash.

audit[5098]: ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=5 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=5098 comm="Shutdow~minator" exe="/usr/lib64/firefox/firefox" sig=11 res=1


Version-Release number of selected component (if applicable):
firefox-wayland-0:67.0-4.fc30.x86_64
glib2-0:2.60.3-1.fc30.x86_64
glibc-0:2.29-15.fc30.x86_64
nspr-0:4.21.0-1.fc30.x86_64
plasma-desktop-0:5.15.5-1.fc30.x86_64
pulseaudio-0:12.2-3.fc30.x86_64

How reproducible:
The segmentation faults and freezing occurred 4 of 4 times when I ran Firefox on Wayland on Plasma and Wayland.

Steps to Reproduce:
1. Boot the F30 KDE Plasma spin
2. Log in to Plasma on Wayland from sddm
3. sudo dnf upgrade --refresh --enablerepo=updates-testing
4. sudo dnf install firefox-wayland
5. reboot
6. Log in to Plasma on Wayland from sddm
7. Run Firefox on Wayland
8. Close Firefox
9. coredumpctl
10. gnome-abrt

Actual results:
Segmentation faults occurred each time I closed Firefox on Wayland in Plasma on Wayland.

Expected results:
No crashes or freezing would occur.

Additional info:

Firefox on X doesn't crash in this way or become unresponsive when I've ran it on Plasma on Wayland. Firefox on X had some odd graphical patterns for less than a second when I've started it in Plasma on Wayland.

The system is an HP laptop with AMD A10-9620P CPU and RADEON R5 GPU.

I tried to use gnome-abrt to submit the information, but the trace generation failed on the server. I submitted the crash information archive. I could attach the abrt files here. The gnome-abrt output was as follows.

Comment 1 Martin Stransky 2019-06-13 08:38:26 UTC
I'm afraid Wayland Firefox is anything but stable on KDE, don't expect anything from it. There are KDE compositor specific issues there and I'm going to look at it when Gnome version is finished.

Comment 2 Martin Stransky 2019-11-05 13:04:21 UTC
Can you please test latest mozilla nightly binaries under Wayland? [1]
Thanks.

Martin, I haven't seen shutdown crashes with the trace as I originally reported with 72.0a1 or 70.0-1.fc31 on Wayland in Plasma 5.16.5 on Wayland in F31. I did get one shutdown crash with 72.0a1 (20191024) which looked to have a different trace I reported at https://crash-stats.mozilla.org/report/index/5e570194-f0d9-4cd5-87e6-8468f0191024  I don't remember if that was with 72.0a1 on Wayland or X though. I think some other processes were taking a lot of resources when I had shutdown firefox which led to its shutdown taking longer than the shutdown timeout length and the shutdown terminator thread killing it as shown by the ShutDownKill signature.

I've seen several segmentation faults when closing thunderbird 60.8.0-1.fc31 to 68.2.0-1.fc31 after the ethernet connection locked up which had similar traces of the crashing threads as in the firefox crashes I reported here. https://bugzilla.redhat.com/show_bug.cgi?id=1755092

The thunderbird segmentation faults involved mozilla::(anonymous namespace)::RunWatchdog(void*) at /usr/src/debug/thunderbird-68.1.0-1.fc31.x86_64/toolkit/components/terminator/nsTerminator.cpp:213  The Shutdown Hang Terminator thread is dealt with in that part of RunWatchdog. CrashReporter::SetMinidumpAnalysisAllThreads(); is called at nsTerminator.cpp:211 to crash the process. thunderbird-68.1.0-1 has the option --disable-crashreporter. thunderbird might've been trying to call the crash reporter which was disabled. The firefox crashes might have had a related reason in that the shutdown was taking longer than the default shutdown timeout length. Thanks.

Comment 4 Ben Cotton 2020-04-30 20:45:22 UTC
This message is a reminder that Fedora 30 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '30'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 30 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 5 Ben Cotton 2020-05-26 17:47:39 UTC
Fedora 30 changed to end-of-life (EOL) status on 2020-05-26. Fedora 30 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
