Podman container exit killing Sway WM (running as a systemd service)

README.md

the issue

sway process stops as soon as podman container exits, eg podman run --rm -it bash -c 'exit 0'

see resolution.md

background

For the last 1-2 years after switching XFCE on Arch Linux to Sway (Wayland) on NixOS I had on and off issues with podman container exits resulting in sway window manager exiting.

It might have been caused by moving sway process inside a systemd service, but at the beginning I was not using enough containers to pinpoint the time.

findings

container's exit code doesn't matter

podman run --rm -it bash -c 'exit 1' has the same effect

the issue is not triggered until container exits

it can run indefinitely, but as soon as container exits Sway closes down

executing from SSH session doesn't trigger the issue

podman run --rm -it bash -c 'exit 0' executed from within SSH session does not impact anything (there is no issue)

container exit results in a clean shutdown of the WM

Nov 08 13:12:10 oams sway[5909]: 00:08:59.248 [DEBUG] [sway/ipc-server.c:386] Sending shutdown::exit event

processes end up in the wrong systemd *.slice when running under Sway

see cgroups-sway.md

they end up in the proper slice when running under SSH, see cgroups-ssh.md

something connects to Sway's IPC when container starts

oci-containers issues on NixOS

Remco> I ended up at https://github.com/NixOS/nixpkgs/issues/249332
Remco> And through that on https://github.com/NixOS/nixpkgs/pull/248315
Remco> Which has:
Remco> "This probably usually goes unnoticed because systemd follows up by sending SIGTERM to all processes in the control group and this is respected. But if this signal is ignored, the container isn't stopped until systemd's timeout of 120 seconds expires."
Remco> So if it sends a sigterm not just for the containers but also for conmon/slirp, that means sway would shut down

resolution.md

Resolution

there are a many ways to problem's resolution:

1. kdn-sway.service:
   1. replace NotifyAccess=all with something else (main/exec)
   2. do not export NOTIFY_SOCKET to dbus-update-activation-environment --systemd
      1. alternatively rename or clear it completely
   3. integrate session manager like sway-systemd to automatically distribute cgroups among applications
      • this might not work for short-lived containers
2. operating system/podman configuration:
   1. operating system: change podman defaults/OS configuration to make it run with --sdnotify=ignore
3. podman implementation:
   1. modify detection of running within systemd service less eager to properly discover this case

Root cause

The root cause is combination of:

1. my window manager (Sway) is running as a systemd service kdn-sway.service of Type=notify and NotifyAccess=all
2. podman by default is sending systemd notifications (sdnotify/systemd-notify)
   • sdnotify implementation
   • setting MAINPID=
3. sending MAINPID= notification results in takeover of the service, search the man page for MAINPID=
   • in effect the latest started container becomes kdn-sway.service's primary process
   • which in turn results in cleanly shutting down Window Manager upon that latest container's exit

follow-up actions

1. implement a working solution:
   1. preferably NotifyAccess=exec or NotifyAccess=main
   2. confirm whether removing NOTIFY_SOCKET export works at all
2. create a https://github.com/containers/podman issue asking for comments/possible resolutions
3. ease discovery of the issue for other people:
   1. create issue at https://github.com/swaywm/sway
      1. add documentation pieces at systemd-integration page https://github.com/swaywm/sway/wiki/Systemd-integration
   2. create issue at https://github.com/NixOS/nixpkgs
4. add a warning to NotifyAccess=all documentation at https://github.com/systemd/systemd
