This is causing SELinux errors.

Comment 1 Lennart Poettering 2009-07-24 12:07:09 UTC

PA stays around as long as it is being used and then terminates itself after 5s or so. "Being used" means that one or more of these conditions are true:

- The XSM session manager of the gdm session still is around

- The gdm session is listed as CK session

- At least one client connection is up, be it via the esd, the native proto or the CLI proto. 

If you want to know if any of the three conditions are true, simply send PA a SIGHUP in which case it will dump it's state to syslog. If you post that here, I can tell you what is keeping PA running.

Why have this logic? Because PA is a per-user, not a per-session daemon, and we want to share it between multiple sessions of the same user. Now, for the gdm user this probably doesn't make much sense, since there won't be more than one gdm user session at the same time. But from PA's perspective this is not really distuingishable. Maybe gdbm should run pulseaudio -k before leaving the gdm session?

And why does SELinux get annoyed by this?

Comment 2 Samuel Sieb 2009-07-25 06:29:38 UTC

I'm using a fully updated F11.  If I cause gdm to beep, then when I login, I will have no sound capability.  There is a pulseaudio process owned by gdm that won't go away.  Checking the log after I login, there are three clients: "GNOME Volume Control", another "GNOME Volume Control" which actually turns out to be gnome-settings-daemon, and libcanberra which is actually metacity.  All these processes use the native connection and are owned by me.

pulseaudio does not have the device open, I can play music if I tell the program to use the direct alsa hardware device.  But I can't start my own pulseaudio daemon because the ports are held by gdm's.  Any program trying to play audio triggers this in the log:

Jul 24 23:22:51 localhost pulseaudio[4905]: alsa-sink.c: Error opening PCM device front:0: Invalid argument
Jul 24 23:22:51 localhost pulseaudio[4905]: sink-input.c: Failed to create sink input: sink is suspended.

Process 4905 is gdm's pulseaudio.

I don't know about any selinux errors as I have it disabled.  It would seem that gdm should kill its pulseaudio daemon before starting the user session.

Which log? syslog after enabling the debug output? Are you sure that the data generated in syslog is actually the state data of the gdm pa process?

PA closes the audio devices when idle, to save power. Ports are held by gdm's? Uh? What do you mean by "ports"? IP ports? PA does not use IP, unless configured so, and the gdm PA certainly is not configured that way.

*** Bug 514992 has been marked as a duplicate of this bug. ***

Comment 5 Bastien Nocera 2009-08-01 01:37:58 UTC

PA should be using CK to go away too. In the default.pa:
### If autoexit on idle is enabled we want to make sure we only quit
### when no local session needs us anymore.
load-module module-console-kit

If PA used CK to know which is the current user session, then it could exit cleanly.

If anyone encounters this and could run:
killall -HUP pulseaudio
when the problem happens and post the resulting output in /var/log/messages, that would be appreciated.

Comment 7 Stephen 2009-08-01 02:43:59 UTC

btw, sound from gdm is incredibly laggy.

With the first name in the gdm chooser selected, press the up arrow. The 'bongo' sound bongs... anything up to 2 seconds later.  That horrible guitar strum login sound always stutters in the middle.

Logged-in desktop sounds are responsive. Music, videos also fine.

Comment 8 Samuel Sieb 2009-08-01 03:52:53 UTC

On a hunch, I checked my default.pa file and discovered that there was a default.pa.rpmnew in the directory.  I moved it into place and now there's no problem with logging in.  However, gdm doesn't make a sound anymore even though it still starts up pulseaudio.  The other part that was probably causing a problem was that I had turned on the native-tcp module, and that is the port that was conflicting.  So if I put that back in, this problem will most likely start all over again.  gdm should kill its pulseaudio daemon or else I will have to set pulseaudio up as a system daemon instead.

1) The gdm session is listed in CK which tells us that PA is still necessary

2) metacity runs as gdm user and is keeps PA running, too.

Where is the problem here?

Comment 10 Samuel Sieb 2009-08-01 20:12:39 UTC

Why is metacity running as the gdm user?

The problem is that metacity is being kept running, that stops gdm's PA from exiting, which stops the user's PA from running.

Can we have some proactivity isn't of gallic shrugging at problems?

Comment 12 Lennart Poettering 2009-08-07 13:46:21 UTC

Hm, so I really don't get what is considered a bug here, and why this is supposedly F12Blocker?

First of all, I don't see what the problem is with PA continuing to run for 5s after the gdm session exited. That's how we handle things for normal user sessions too, and I don't see how gdm should be handled differently here. Bastien, you mention "SELinux errors", could you please be a bit more elaborate about that?

I also get the idea that the output in #6 does not actually fit here. It suggests that the gdm session is actually active, given that metacity is still around and CK shows it as actvie still. In which case everything is fine. And if this indeed a dead session and CK is wrong and metacity some kind of orphan then the bug should be fixed in GDM or metacity or CK -- and not PA?

Bastien, please enlighten me what's the bug here!

The problem is that the GDM session isn't getting cleaned up properly.

Well, maybe it's not a bug in PulseAudio then, but in GDM not cleaning up it session properly. Or a bug in gnome-session.

You get errors through auditd about rejected messages. PulseAudio is trying to talk to bluetoothd, but as it belongs to GDM, it's not on the console. The bluetoothd D-Bus rules reject the message.

Hey, maybe not. A bit of swamp-draining would be appreciated. PA doesn't run in a vacuum.

> Bastien, please enlighten me what's the bug here!  

The problem is that, at the end of the day, audio doesn't work as expected once the user's logged in. That's a blocker.

Comment 15 Samuel Sieb 2009-08-07 14:37:48 UTC

I would be inclined to call this a gdm bug, that it should kill its pulseaudio daemon before logging the user in.  The problem is that if I enable the TCP protocol, the second pulseaudio session can't run.  Or should I just be running a --system pulseaudio daemon instead?  This also affects multi-user switching.

Hmm? How's that? I mean, PA tries its best to escape the session since it is supposed to be a user daemon, not a session daemon.

So I really don't see how this is a bug in gdm either. There is no way how gdm could cleanup PA, since it cannot keep track of processes that try to escape its session management. 

I mean, you can argue that PA escaping the session manager is a bad idea, but that's a different question, and as long as D-Bus lacks a user bus this is going to stay that way. Also this was already discussed in long in the past.

Also, I don't see why no cleaning up the session correctly is a bug at all.

But neither gdm nor gnome-session could keep track of PA here, since PA actively tries to escape them. (by doing double fork, yadda yadda).

Hmm, so this is about bluetoothd usng at_console?

How exactly does audio not work? What's broken? A lingering PA from gdm should not influence the PA of the user session. 

Please describe how exactly the user's PA instance fails to work.

No, you should not enable it globally for all sessions. I mean, if you enable it globally all sessons will fight for the TCP port, isn't that expected and obvious?

The way to go here is to enable it locally for your user. You can do that very easily via paprefs, or simple by editing ~/.pulse/default.pa.

It's a bug because it ends up causing problems in the user's session.

That causes errors that are popped back through auditd, and into the SELinux applet.

The bug is that gdm's PA isn't releasing the audio device, and the user's PA doesn't work.

Comment 19 Matthias Clasen 2009-08-07 17:37:25 UTC

Really, just make the gdm pa die with the login session. I realize there may be uses cases that require PAs odd per-user, session-escaping behaviour, but none of them involve the gdm user...

Comment 20 Lennart Poettering 2009-08-19 15:53:19 UTC

Hmm, there seems to be no way to synchronously kill PA from gdm when the gdm session ends. All we can do is do it asynchronously -- which we already do (although with a 2s delay).

So I am not sure how to fix this properly. Also, I am not really that concerned about this if all that this is about is that dbus logs a message.

No, the bug is that audio doesn't work in the user's session.

Comment 22 Lennart Poettering 2009-08-19 20:03:20 UTC

What exactly doesn't work? Could you please be more elaborate? Is PA unable to discover the device? Does it appear in g-v-c?

Comment 23 Lennart Poettering 2009-08-24 02:26:59 UTC

OK, I think I tracked this down. It's a race between gdm's PA closing of the audio devices and the user session's PA opening them. Is fixed now upstream and would be in rawhide too, but perl is broken and makes it impossible for me to buid PA in koji.

Comment 26 Lennart Poettering 2009-09-17 02:34:54 UTC

Hmpf, these are different bugs.

BlueZ is not really compatible with session switching. That all that is to it.

PA not dying is unrelated to it. which is what this bug is about. Or which i made it to be about given that originally it was about multiple unrelated things... Will split this now again.
