Original GitHub issue: https://github.com/netblue30/firejail/issues/3464

Bug and expected behavior

  • Describe the bug.
    Upgrading from atom 1.46.0 to 1.48.0 breaks starting atom under firejail.
  • What did you expect to happen?
    atom to start normally.

No profile or disabling firejail

  • What changed calling firejail --noprofile PROGRAM in a shell?
    atom starts-up normally.
  • What changed calling the program by path=without firejail (check whereis PROGRAM, firejail --list, stat $programpath)?
    atom starts-up normally.

Reproduce
Steps to reproduce the behavior:

  1. Run in bash firejail atom
  2. See error:

No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 10 (buster)
Release:	10
Codename:	buster
  • Firejail version (output of firejail --version) exclusive or used git commit (git rev-parse HEAD)
firejail version 0.9.58.2

Compile time support:
	- AppArmor support is enabled
	- AppImage support is enabled

  • What other programs interact with the affected program for the functionality?
    To my knowledge: git, GVFS Trash
  • Are these listed in the profile?
    Yes.

Additional context
I have a strong feeling that the issue is related to change in PR#20799, which fixes the Issue#20756.

My atom.profile:

# Other fixes

I gradually commented out certain entries in my atom.profile just to test, the following does not prevent atom from starting-up:

Originally created by @kmotoko on GitHub (Jun 11, 2020). Original GitHub issue: https://github.com/netblue30/firejail/issues/3464 **Bug and expected behavior** - Describe the bug. Upgrading from `atom` `1.46.0` to `1.48.0` breaks starting `atom` under `firejail`. - What did you expect to happen? `atom` to start normally. **No profile or disabling firejail** - What changed calling `firejail --noprofile PROGRAM` in a shell? `atom` starts-up normally. - What changed calling the program *by path*=without firejail (check `whereis PROGRAM`, `firejail --list`, `stat $programpath`)? `atom` starts-up normally. **Reproduce** Steps to reproduce the behavior: 1. Run in bash `firejail atom` 2. See error: ``` Reading profile /etc/firejail/atom.profile Reading profile /etc/firejail/atom.local Reading profile /etc/firejail/globals.local Reading profile /etc/firejail/disable-common.inc Reading profile /etc/firejail/disable-passwdmgr.inc Reading profile /etc/firejail/disable-programs.inc Warning: networking feature is disabled in Firejail configuration file Parent pid 13545, child pid 13546 Child process initialized in 47.07 ms /usr/bin/atom: line 190: 14 Trace/breakpoint trap nohup "$ATOM_PATH" --executed-from="$(pwd)" --pid=$$ "$@" > "$ATOM_HOME/nohup.out" 2>&1 [14:0611/105406.114486:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly.

Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster ``` - Firejail version (output of `firejail --version`) exclusive or used git commit (`git rev-parse HEAD`) ``` firejail version 0.9.58.2 Compile time support: - AppArmor support is enabled - AppImage support is enabled - chroot support is enabled - file and directory whitelisting support is enabled - file transfer support is enabled - networking support is enabled - overlayfs support is enabled - private-home support is enabled - seccomp-bpf support is enabled - user namespace support is enabled - X11 sandboxing support is enabled ``` - What other programs interact with the affected program for the functionality? To my knowledge: `git`, `GVFS Trash` - Are these listed in the profile? Yes. **Additional context** I have a strong feeling that the issue is related to change in [PR#20799](https://github.com/atom/atom/pull/20799), which fixes the [Issue#20756](https://github.com/atom/atom/issues/20756). My `atom.profile`: ``` # Firejail profile for atom # Description: A hackable text editor for the 21st Century # This file is overwritten after every install/update # Persistent local customizations

Other fixes noblacklist ${HOME}/.pythonrc.py ``` I gradually commented out certain entries in my `atom.profile` just to test, the following does not prevent `atom` from starting-up: ``` # Firejail

The upstream profile exists (`find / -name 'firejail' 2>/dev/null`/`fd firejail` to locate profiles ie in `/usr/local/etc/firejail/PROGRAM.profile`) - [ x] Programs needed for interaction are listed.

Is force-nonewprivs set in /etc/firejail/firejail.config?

It was commented out, I tried both force-nonewprivs no and force-nonewprivs yes with no luck (the error did not change).

I'm out of ideas for now. Maybe you need to also ignore nogroups

firejail --ignore=nonewprivs --ignore=noroot --ignore=nogroups --ignore=protocol --ignore=seccomp --ignore=caps.drop --caps.keep=sys_admin,sys_chroot /usr/bin/atom

That didn't work either. I will keep playing with the rules and post if I find something.

Because --noprofile works, we know that it is caused by one (or more) command in the profile. If you comment the full profile and then uncomment it line for line you will find it. However, I'm afraid, that it is a interaction between more commands, that is harder to debug.

@rusty-snake I'm able to get it to work if I comment out
caps.drop all
nonewprivs
noroot
protocol unix,inet,inet6,netlink
seccomp

Naturally I want to tighten this down a bit but hopefully I can get a fix in within a day or so.

@rusty-snake thanks for catching that! I'll put in a fix under etc-fixes for 0.9.58 and the other distro-supported releases (0.9.52, 0.9.58, and 0.9.60). This would skip 0.9.44, but since Debian 9 goes EOL in less than a month and 0.9.58 is in its backports, it may be better not to patch this one...
