Firefox crash on OpenBSD 6.6

[joancatala]

Hi,
I use OpenBSD as a Desktop system since many years. Now, I installed from zero the OpenBSD 6.6 on a laptop (I had 6.5 last week) and everything works well but the Firefox ESR crash all the time when I go to a video website (Youtube, Twitter with some videos, etc).

I recorded a video. On the right, OpenBSD 6.5 with Firefox ESR 60 and everything works well. ON the left OpenbBSD 6.6 with Firefox ESR 68 and crash all the time (on the video is the homepage of Youtube):

Can somebody tell me some trick?
Are you experimenting the same on 6.6?

Browser users should be running with login class "staff" to ensure they have enough resource to run the browser. The "default" class does not.


Also, review the pkg-readme. There are discussion for settings for amdgpu video cards, using HTML5 video, and graphic acceleration.

I change nothing, and my user is on staff login class by default:

x250$ userinfo joan                                                                                                                                                                                                 
login   joan

You may have made no changes since OpenBSD 6.5, but changes have occurred.

OpenBSD has had 519 significant changes between 6.5 and 6.6.

As for your browser: at OpenBSD 6.5-release, firefox-esr was 60.8.0. At OpenBSD 6.6-release, it was at 68.1.0. And there is a -stable port that was committed earlier today to bring that to 68.2.0. A -stable package will likely be available soon.

Try a different browser, or update to the -stable port/package.

Now it works. I can browse Youtube or Vimeo or Twitter withouth any problem.
How?

I added a USB bluetooth receptor (this ---> https://www.amazon.es/Creative-BT-W2...gateway&sr=8-1) and If I do dmesg:

firefox-esr[60046]: pledge "tty", syscall 54
firefox-esr[60046]: pledge "stdio", syscall 74
uaudio0 at uhub0 port 2 configuration 1 interface 1 "Creative Labs Creative Bluetooth Audio W2" rev 2.00/1.00 addr 6
uaudio0: class v1, full-speed, sync, channels: 2 play, 1 rec, 0 ctls
audio1 at uaudio0
uhidev0 at uhub0 port 2 configuration 1 interface 3 "Creative Labs Creative Bluetooth Audio W2" rev 2.00/1.00 addr 6
uhidev0: iclass 3/0, 3 report ids
uhid0 at uhidev0 reportid 1: input=2, output=0, feature=0
uhid1 at uhidev0 reportid 2: input=18, output=18, feature=0
uhid2 at uhidev0 reportid 3: input=64, output=64, feature=0

So, now I can use Mozilla Firefox 68 ESR without any problem.

I believe I may see the problem. It is not related to your added Bluetooth device. I see:

firefox-esr[60046]: pledge "tty", syscall 54
firefox-esr[60046]: pledge "stdio", syscall 74

The kernel is halting processes for violating pledge(2) restrictions. Last year, the port maintainer posted the following, in part:

If you get an abort from pledge, collect:
- what you were doing, on which website, etc etc
- firefox stdout, to figure out the various processes/pids running
- what process was killed, for which syscall (ie in dmesg)
- have a look at ~/firefox.core via egdb, try to get a meaningful trace of the
codepath that triggered the pledge. There might be dragons/hidden signal
handlers.
- try to reproduce the crash inside ktrace/kdump (ie start ffx via 'ktrace -di
-t cp -- firefox', thx kn@)
- the codebase is huge, but try to figure out where that codepath is.
https://dxr.mozilla.org/mozilla-release/source/ is here for that
