Original GitHub issue: https://github.com/netblue30/firejail/issues/3351

Bug Description

I can not play files using mplayer unless adding the directory of the video file as whitelisted directory.
I can not whitelist any directory so that I may play a video file in any ($HOME) (sub-)directory.

This is my /home/vk/.config/firejail/mplayer.profile showing the error behavior:

noblacklist ${HOME}/.mplayer                                                                                                                                                                                                                                                              
noblacklist /etc/mplayer/                                                                                                                                                                                                                                                                 
noblacklist /run/user/1000/pulse
net none

Behavior change on disabling firejail

vk@host ~2d % firejail --noprofile mplayer video.mp4 
Parent pid 9825, child pid 9826
Error: /home/vk/.config is a symbolic link
Error: proc 9825 cannot sync with peer: unexpected EOF
Peer 9826 unexpectedly exited with status 1
1 vk@host ~2d %

To Reproduce

mplayer profile:

noblacklist ${HOME}/.mplayer                                                                                                                                                                                                                                                              
noblacklist /etc/mplayer/                                                                                                                                                                                                                                                                 
noblacklist /run/user/1000/pulse
net none
  1. having the mplayer profile as above
  2. invoking /usr/bin/firejail --debug --profile=/home/vk/.config/firejail/mplayer.profile mplayer video.mp4
  3. I get error
Error: /home/vk/.config is a symbolic link
Error: proc 7521 cannot sync with peer: unexpected EOF
Peer 7522 unexpectedly exited with status 1

For detailed debug output, see http://paste.grml.org/hidden/ecc96efa/

Expected behavior

Expected behavior would be that I may play back video files without whitelisting the directory of that video file.

Workaround

mplayer profile:

noblacklist ${HOME}/.mplayer                                                                                                                                                                                                                                                              
noblacklist /etc/mplayer/                                                                                                                                                                                                                                                                 
noblacklist /run/user/1000/pulse

# Additional line fixing the issue with this workaround: this is the directory of "video.mp4"
whitelist ${HOME}/tmp/2del/

net none
  1. having the mplayer profile as above
  2. invoking /usr/bin/firejail --debug --profile=/home/vk/.config/firejail/mplayer.profile mplayer video.mp4
  3. mplayer does play back video file

Desktop

  • Linux distribution and version: Linux Debian 10 buster
  • Firejail version: 0.9.58.2

Additional context

I freshly upgraded from Debian oldstable yesterday. Before the upgrade, my custom profile without the additional whitelist did work fine. Unfortunately, I did not write down the previous firejail version.

Broken down: firejail can not local user profiles if ~/.config is a symlink.

I also did some experiments because my ~/.config is a symlink:

whitelist ${HOME}/.config/firejail
whitelist ${HOME}/hosts/sherri/config/dot-config/firejail

However, when video playback worked with just adding the whitelist for the video directory (and not the whitelist lines for the .config folder), I don't think that the symlink issue of .config is related to my issue.

Correct me if I'm wrong.

Could you try with the noautopulse option? It should get you rid of the error.
I'll try to add a fix for that aspect.

Hi @smitsohu,

Adding noautopulse to my profile file did resolve the issue. Without knowing the exact details, I consider this to be a solution and not a workaround, closing the ticket for now.

Thanks!
