Chromium 115 segfault and Firefox random crashes [SOLVED]

[NathanZachary]

Hello,

I just finished a world update, and now Chromium is segfaulting at startup:

Code: Select all

$ chromium

 Possibly a General Protection Fault, can be due to a non-canonical address dereference. See "Intel 64 and IA-32 Architectures Software Developer’s Manual", Volume 1, Section 3.3.7.1.

I found some bug reports regarding AMD GPUs, but they don't seem to be the same problem that I'm seeing.

I appreciate any help.

there are known bugs in mix with newer versions of glibc-2.37.* and also maybe gcc-13.1.* - don't know about chromium 115.* ?

IIRC, chromium 114.* is current stable and is working great here (ungoogled-chromium).

[NathanZachary]

Thanks for the information. I had previously been on Chromium 113, then upgraded to 115, bug with the segfaults I downgraded to 114 as a test. 114 seems to be working just fine. As I am using glibc-2.37 and gcc-13.1.1, I'll just stick to Chromium 114 for now. Maybe things will stabilise in the near future. If not, I'll look further into it.

This is the first I've heard of such a thing. Can you give a source?

[CooSee]

sorry, i can't find it anymore !

for a long time, i always used ~amd64 ebuilds, but someday i came across this annoying oh snap issue with ungoogled-chromium >>> every tab just crashed.

after some search i found out that this was caused by glibc from testing! - also tried a patch for glibc without luck.

reinstalled gentoo - thx to usepkg=y, but this time only stable and everything went as expected - same make.conf - no oh snap crashes anymore.

That might be an issue that has occasionally hit Firefox as well. In the Firefox case, and if Chromium is what I suspect, then in its case too, the problem is a design bug in the browser. They set a seccomp filter that kills the process if any library anywhere in the process uses any system call that was not on the allow-list shipped with the browser, then they're surprised when libraries they don't control, such as glibc, suddenly start using system calls they did not allow. The glibc project never promised the browser that it would not add use of new system calls as the glibc developers see fit, so it is a design bug in the browser to assume that they can build an exhaustive list that is valid not only on release day, but indefinitely into the future as new versions of other libraries, such as glibc, are put into use. Historically, this bug was exacerbated by needing a new release from the browser project to extend the allow-list to cover the newly used system calls. I don't know if they ever learned their lesson and added a mechanism to allow new system calls without requiring a new release. The only reason glibc testing is relevant in those cases is that it is the most likely place for new system calls to show up first, so it is the most likely to trigger the overzealous system call filter.

Yes, it's a fundamental flaw in seccomp. That said, I've heard 0 reports of this with glibc-2.37.

sultan, one of the Chromium maintainers in Gentoo, found this thread and identified it as bug 909198. That should fix your problem, thanks!

With Firefox 114 (and now 115), I'm getting random crashes. Unlike Chromium 115, Firefox will start without segfaulting. However, seemingly randomly it will crash:

Is it possible that these two problems are related?

[CooSee]

sometimes i get these too - Exiting due to channel error.

have you used Developer Tools in FF? - i read somewhere that this channel error also happens while using DT.

i still use glibc-2.36.* and gcc-12.* and i just compiled ungoogled-chromium (pf4public) and firefox (pg_overlay).

no (big) issues - no crashes - except, couple of days ago all of a sudden traps: chrome[9344] trap int3 ip:64573fb16f11 sp:7ffdfb1c2a00 error:0 in chrome[64573f149000+ab63000]

FF is more chatty now - i get many JavaScript errors or console.warn: LoginRecipes: "Falling back to a synchronous message for: https://forums.gentoo.org." etc.

other than that, everythings fine - using wayland only system here, no xwayland.

[NathanZachary]

Though I haven't seen reports of these problems being related to glibc-2.37, it's possible that that's when the problems started. Or maybe it's even related to glib-2.76 like the tint2 tray icon bug. At this point, I think I'm going to have to delve more deeply into things as there are several instability problems that I'm encountering. I haven't had it like this in a long time.

[CooSee]

don't want to confuse anyone, because i assume this is a glibc issue!

found this https://bugs.kde.org/show_bug.cgi?id=471559 and https://arcolinuxforum.com/viewtopic.php?p=14376 for those using nvidia + plasma - egl-wayland 1.1.12 seems to be the culprit.

[NathanZachary]

I'm not sure that it is going to do anything to help, but I decided to start with a trivial-to-implement potential fix: removing my profile and starting with a fresh one. It would be nice to have an easy fix, though.

EDIT: Nope, still crashing.

[CooSee]

@NathanZachary

if it's not much to ask, please try by downgrading gui-libs/egl-wayland to 1.1.11_p20230202-r1.

the ATTENTION Bug is explained here https://bugzilla.mozilla.org/show_bug.cgi?id=1744389

[NathanZachary]

I wouldn't mind doing any tests, but I'm using Xorg not Wayland (so egl-wayland isn't installed).

Please stop assuming! The 'illegal instruction' implies this is likely https://bugs.gentoo.org/908412 (caused by GCC LTO).

Also, when it gets to the point where you really have no clue & the forum suggestions have been exhausted, please do search bugzilla and if no duplicates exist, file a bug.

EDIT: I realise now you might've meant "I don't want to confuse anyone because I assumed before that it's a glibc issue"?

[NathanZachary]

I don't know that it is related to GCC LTO in my case:

@sam_
If it would be helpful, I can add anything you may need to Bug 908412. Please just let me know if you would like me to do any testing, and thanks for your insights.

Okay, so it's something new, or you have an old version of NSS installed (what version of dev-libs/nss do you have? If it's 3.90, please upgrade to 3.91.)

The only other thing which came to mind was the elfhack bug but that never applied to Clang anyway, and indeed, the GCC LTO one is irrelevant here for the same reason.

If you can consistently reproduce the "Illegal instruction" error, please file a new bug and we'll dig into it there.

[NathanZachary]

I'm running =dev-libs/nss-3.91. I can't reproduce the problem consistently by any means, but I would say that the crashes happen 10+ times per day. For now, I have filed Bug 909676 for tracking. I can run any troubleshooting tests that would be helpful; please just let me know in the bug.

Thanks again for your help.

i just noticed that i'am also using sys-libs/glibc-2.37-r3 - re-emerged FF and chromium - no crashes so far on my wayland only system.

it seems that this is happening more often, while using X11.

[gorg86]

Kernel 6.4.0 caused FF to crash on my machine, I downgraded to 6.3.9 and linux-headers 6.3. Got no problems since then.

I'm using 6.4.2. No crashes here.
Firefox 115 works well. What did you do to crash it?

[gorg86]

It crashed randomly, most of the time when opening a new tab. The error it spit out on the console was always the same GPU or mesa related thing (I don't remember exactly).

You have hwaccel forced?

[gorg86]

The checkbox "Use hardware acceleration when available" is activated. I can't reproduce that error right now, but I think AMDGPU was causing it.
