Original GitHub issue: https://github.com/netblue30/firejail/issues/6035

Description

Ubisoft connect doesn't work with Lutris's default profile.

Steps to Reproduce

  1. ln -s /usr/bin/firejail /usr/local/bin/lutris
  2. cp /etc/firejail/lutris.profile ~/.config/firejail/lutris.profile (to a whitelist a single folder)
  3. firecfg --fix
  4. Launch Lutris
  5. Start Ubisoft Connect [WINE- Latest Version]

Expected behavior

Ubisoft Connect should work without throwing an error

Actual behavior

Lutris gave an API error[lutris-upc]

Behavior without a profile

  1. rm /usr/local/bin/lutris

Ubisoft Connect starts fine without Firejail profile

Environment

  • Arch Linux x86-64
  • firejail version 0.9.72

Checklist

  • The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
  • I can reproduce the issue without custom modifications (e.g. globals.local).
  • The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
  • The profile (and redirect profile if exists) hasn't already been fixed upstream.
  • I have performed a short search for similar issues (to avoid opening a duplicate).
    • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
  • I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

Setting ignore to seccomp !modify_ldt and seccomp.32 !modify_ldt fixes this issue.

ignore seccomp !modify_ldt
ignore seccomp.32 !modify_ldt

Should I close this issue or keep it open?

Thank you for reporting. Disabling the seccomp filter like you did might fix your issue, but the lutris sandbox would be more hardened if we could ascertain an improved, working filter. Let's keep this open so people can chime in to try determining such a replacement seccomp filter.

Could you try to find a working seccomp filter? There's more info here.

@glitsj16
I don't know much about this to offer any help, I sort of found out by trial and error.
I followed the link your provided, and try to find out which seccomp was causing issues.
When I run:
firejail --seccomp-error-action=log /usr/bin/lutris
Everthing works fine, and journalctl doesn't list anything

When I run :
firejail /usr/bin/lutris
I get original issue

Anyhing in journalctl when you --seccomp-error-action=EPERM (the default) and --seccomp-log=yes?

Argh, my bad. You'll need to change the default # seccomp-log no to seccomp-log yes in /etc/firejail/firejail.config... Apologies for the confusion.

No worries, I edited firejail.config, rebooted and tried again.
Term1) sudo journalctl --grep=SECCOMP --follow

Term2) firejail --seccomp-error-action=EPERM /usr/bin/lutris

Original Issue and nothing was listed on journalctl

I tried: firejail --seccomp-error-action=log /usr/bin/lutris again

And it seems to work fine, but nothing is being listed in journalctl

I feel like this a problem is unique to me. If its not reproducible, then we can close this issue.

No problem. I'll try to reproduce over the weekend, although my hardware isn't any good for gaming & wine. We can keep this open for a while. Other collaborators/users might have input.

I un-commented allow-debuggers in .config/firejail/lutris.profile
Also have; seccomp-log yes in /etc/firejail/firejail.config

Then I re-ran the test.

Term1) sudo journalctl --grep=SECCOMP --follow

Term2) firejail --seccomp-error-action=EPERM /usr/bin/lutris

Now I no longer get the original issue, nothing is listed in journalctl

I tried: firejail --seccomp-error-action=log /usr/bin/lutris

I think I found the right syscalls for this issue: ptrace,clone3 (and optionally) process_vm_readv.

I had journalctl -f | grep "kernel" running, looking for syscalls lutris was using
I need to whitelist just ptrace and clone3, journalctl did list for process_vm_ready when a game was running, but it didn't crash the game.

seccomp !modify_ldt,!clone3,!ptrace,!process_vm_readv
seccomp.32 !modify_ldt
