Description of problem: When opening system firefox after updating my laptop in Fedora 36 (I usually use Nightly), tab crashes. This doesn't happen with the Mozilla official builds. Restoring the tab seems to avoid it crashing again.

Version-Release number of selected component (if applicable): 99.0.1 (64-bit)

How reproducible: Always

Steps to Reproduce:
1. Open Firefox

Actual results: Your tab crashed.

Expected results: It doesn't?

Additional info:

See gdb stack above. Crash report: https://crash-stats.mozilla.org/report/index/60c7e227-6e7e-4aa4-bf24-583a40220415

It's failing when initializing system nss, in a similar fashion as bug 2074587, inside the gtprgnam("pkcs11") call.

In __GI___nss_lookup ni is 0x7fffbe8ae728, but *ni is null, and that gets dereferenced in __GI___nss_lookup_function.

Martin is this known? If not is there something I can do to help diagnose?

Comment 2 Martin Stransky 2022-04-19 12:57:03 UTC
Let's move to NSS for further investigation.

Comment 3 Bob Relyea 2022-04-19 16:19:43 UTC
Moving to p11-kit. The crash is in p11-kit, trying to look up an function in the other NSS (Name Switch System).

Comment 4 Daiki Ueno 2022-04-19 18:04:52 UTC
The crash is in a PKCS#11 module loaded by p11-kit, as p11-kit does not call getpwnam by itself. I suspect it is opencryptoki from the symbols appear in the backtrace:

Comment 5 Emilio Cobos Álvarez (:emilio) 2022-04-19 18:09:15 UTC
Note that I also hit another issue with that package after the update, reported as bug 2074587. This crash happened after working around that as described there.

I've updated my Fedora 36 install with latest packages, but I am still unable to use Firefox extensions. Every time I use an extension dmesg reports:

WebExtensions[5979]: segfault at 0 ip 00007f0b6b51581d sp 00007ffdfc714c70 error 4 in libc.so.6[7f0b6b403000+173000]

including the latest opencryptoki update? Does the workaround from https://bugzilla.redhat.com/show_bug.cgi?id=2074587#c5 fix your problem?

Hi Dan,
I've installed recent updates today, run `dnf distro-sync` to have all packages aligned with upstream, but that doesn't help with segfaults. I have version 3.17.0-7.fc36 of opencryptoki installed on my system and it's the main problem. Once I remove the package no more segfaults for me.
