Comment 1 Michael Jones 2024-07-19 06:27:11 UTC
the build log, even when compressed with `xz -9` is larger than the 1000kb limit.

I think it's time for bugzilla to have a larger filesize limit...

Comment 3 r7l 2024-07-19 20:23:03 UTC
Can confirm this issue. Having the same problem.
Comment 4 Joonas Niilola gentoo-dev 2024-07-22 13:59:30 UTC
Our Firefox "rapid" is way more open with sandbox restrictions compared to esr.

Rapid: https://gitweb.gentoo.org/repo/gentoo.git/tree/www-client/firefox/firefox-128.0.ebuild#n543
ESR: https://gitweb.gentoo.org/repo/gentoo.git/tree/www-client/firefox/firefox-115.13.0.ebuild#n584

Basically you'll want to add:
  addpredict /dev

or
  addpredict /dev/udmabuf 

to the ebuild under this "if use pgo ; then" block. I don't think this will be fixed for 115esr as 128.1.0 esr ebuilds will be out in a couple of weeks, and those are going to carry the more lenient sandbox accesses.

There was something similar for libreoffice.

Thanks, I was able to build firefox-115.13.0:esr with pgo after adding addpredict /dev/udmabuf to the ebuild:

		if use pgo ; then
			# Update 105.0: "/proc/self/oom_score_adj" isn't enough anymore with pgo, but not sure
			# whether that's due to better OOM handling by Firefox (bmo#1771712), or portage
			# (PORTAGE_SCHEDULING_POLICY) update...
			addpredict /proc

			# May need a wider addpredict when using wayland+pgo.
			addpredict /dev/dri
			addpredict /dev/udmabuf



 # emerge -vp firefox

These are the packages that would be merged, in order:

Comment 7 Maksym Sditanov 2024-08-06 18:15:28 UTC
Looks like this issue fixed in ebuild firefox-128.0.3.ebuild in line 548:

 541         if use pgo ; then
 542             # Update 105.0: "/proc/self/oom_score_adj" isn't enough anymore with pgo, but not sure

 544             # (PORTAGE_SCHEDULING_POLICY) update...
 545             addpredict /proc
 546 
 547             # Clear tons of conditions, since PGO is hardware-dependant.

Maybe, it has sense to backport this fix to www-client/firefox-115.13.0:esr::gentoo

If you make a PR updating that in 115.14.0 before it's stabilized, I'll merge it. Otherwise I'm too lazy to touch 115esr anymore, since 128.1.0esr is in the tree already and 115esr will be cleaned ~soon altogether.

It's not a huge change but it requires testing and I'd rather focus on 129+ and 128esr+.

That being said, 128.1.0esr should work for everyone since it has more relaxed sandbox restrictions.
