Works with VBoxSVGA and VMSVGA when 3D acceration is enabled but for some reason not VBoxVGA.

Why don't you just start onionshare from the application menu?

#2 Updated by scootergrisen 9 months ago

OnionShare in the application menu runs onionshare-gui.

The .desktop file says:

Exec=/usr/bin/onionshare-gui

If i select OnionShare in the application menu i see this with "sudo dmesg":

[ 879.075447] audit: type=1400 audit(1549231684.431:39): apparmor="DENIED" operation="file_mmap" profile="/usr/bin/onionshare-gui" name="/usr/lib/VBoxOGL.so" pid=11415 comm="onionshare-gui" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0

I won't have time to look into this soon unfortunately. But putting it on my radar anyway.

#4 Updated by scootergrisen 8 months ago

If you got some ideas on what i could try to get closed to what the problem might be i could try that in the mean time.

This seems to be a bug in the AppArmor profile we ship. It seems it's been upstreamed but is not shipped in the Debian package yet (see #11929#note-15) so let's fix it on our side for now. I'll check if the problem is in an abstraction.

#8 Updated by intrigeri 8 months ago

Reproduced.

#9 Updated by intrigeri 8 months ago

At first glance, it looks like /etc/apparmor.d/abstractions/base expects all shared libraries to be called lib*.so, while this one is called VBoxOGL.so.

Asked on https://gitlab.com/apparmor/apparmor/merge_requests/345 why the policy is the way it is.

  • Target version changed from Tails_3.13 to Tails_3.14

Pinged on the upstream discussion. I don't expect we'll reach a conclusion that we can implement in time for 3.13.

It seems that consensus was reached upstream. I'd rather resolve the conflicts of the proposed fix with our config/chroot_local-patches/apparmor-aliases.diff only once, so my plan is:

  1. get this merged upstream
  2. apply the fix in Debian, batch this with other bugfixes and get this unblocked for migration to Debian testing; I'll try to do this at the BSP at the end of March
  3. once it's in Debian testing, feature/buster will FTBFS and I'll have to resolve the merge conflict

#16 Updated by CyrilBrulebois 7 months ago

I think I now understand what the current (in feature/buster) patch does, but I'm not sure how to forward these changes with the new apparmor code (as of 2.13.2-10).

I'd be happy to get from you an updated hunk for the /etc/apparmor.d/abstractions/base file…

I've done one of the possible conflict resolutions and will push once I confirm it at least fixes the FTBFS. Then our test suite should tell us if my conflict resolution breaks stuff.

@CyrilBrulebois, @hefee I've pushed a candidate conflict resolution that allows the build to reach the next failure (#16604).

What this ticket was about has been fixed on feature/buster. Please file a new, dedicated ticket if I got the merge conflict resolution wrong :)
