wpa_supplicant service does not stop

The first symptom of my problem was that my PC was not shutting down - it hung on a black screen with cursor blinking in the top left corner. To troubleshoot the issue I removed the quiet kernel parameter to see what is going on. I discovered that the system hangs on stopping Network Manager and WPA supplicant. This was consistent with the fact that if I performed a power off before the PC (laptop, actually) connected to wifi, the shutdown went normally. So, to test the theory further, I wanted to manually stop wpa_supplicant.service. However, when I do this

systemctl stop wpa_supplicant.service

the stopping does not complete, it hangs and does not return the control over the console. If I display the status of the service from another console, it shows as deactivating. Manually killing the wpa_supplicant process also does nothing. The only way I figured to get out of this situation is to issue the Alt+SysRq+B shortcut to force reboot the system. The wpa_supplicant logs for that particular boot when I attempted to stop the service look like this:

The log shows "Stopped WPA supplicant" but that is actually not the case, the process is still there. When the system shutdown fails, I think what is happening is that it "stops" the service like this but the process is still hanging there, causing the shutdown process to hang as well. But I don't know, I'm not very knowledgeable in these areas.

Another weird thing is that the wpa_supplicant.service is not enabled but is started anyway, even if NetworkManager.service is disabled. I cannot see it in systemctl list-dependencies either.

What could be the the problem? How is it possible that a service is started without it being neither enabled or wanted by another service? How can I make the service work as expected (i.e. stop it when I or the system tells it to stop)?

I'd be happy to provide additional info if instructed.

Re: wpa_supplicant service does not stop

Services can be started by invocation through other services which is e.g. what NetworkManager does, it calls wpa_supplicant itself. In general this reads like classic multiple networking services fighting for the interface. What's your output for

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

I have written, I found wpa_supplicant started just after reboot even when NetworkManager is disabled and not started.

Please post a complete system journal from a boot where wpa_supplicant is started despite NM being disablded.

Re: wpa_supplicant service does not stop

Invoked by geoclue (which is invoked by gnome-shell)

Most likely because wifi is enabled in /etc/geoclue/geoclue.conf - there's no effort to stop it in this journal, but I guess you need to stop geoclue first.

Re: wpa_supplicant service does not stop

Nice catch. I have disabled wifi in /etc/geoclue/geoclue.conf and wpa_supplicant.service is not starting anymore. However, the original problem remains - when I actually start NetworkManager.service, which in turn starts wpa_supplicant.service, I am unable to stop it. A manual attempt to do this (systemctl stop wpa_supplicant.service) looks like this:

čen 11 07:39:28 eddie systemd[1]: Stopping WPA supplicant...
čen 11 07:40:58 eddie systemd[1]: wpa_supplicant.service: State 'stop-sigterm' timed out. Killing.

čen 11 07:45:29 eddie systemd[1]: Stopped WPA supplicant.

And indeed, the process is still happily running.

By the way, basically the same thing happens with NetworkManager.service too:

The system refuses to shut down too (my very original problem).

Does it meet the PID wpa_supplicant.service thinks it has?

What's its state?

Re: wpa_supplicant service does not stop

It's likely waiting for some I/O ("D" state) - you could strace it to see where it's hanging around or check the dmesg for IO errors.

Does the wifi NIC work? Can you ping an IP over it? (Before trying to take it down)?
Is it in the "D" state before the attempt to terminate it?

Re: wpa_supplicant service does not stop

When wpa_supplicant and NetworkManager are up and running, everything works just fine, I can ping, wget, whatever. When I stop wpa_supplicant, I cannot ping anymore, even before systemd starts reporting the term/kill timeouts.
It seems not to be in the D state before the termination attempt:

Re: wpa_supplicant service does not stop

The context looks routing/filtering related…
Wild guess: disable docker & f@h and reboot - can you terminate wpa_supplicant now?

Though ultimately it's likely pipewire :-P

Re: wpa_supplicant service does not stop

Disabling docker and f@h did not help. Thinking about pipewire, I have a feeling that I first started to notice such problems some time around the switch to pipewire so it might be related. However, I disabled everything pipewire but wpa_supplicant still refuses to terminate when asked.
