(Resending this, as the mail seems to have been eaten on the way to the
linux-usb mailing list.)

Hi Pierre,

I'm forwarding this to the linux-usb mailing list, as they might have
some insight into your issue.  I think this is a kernel issue since it
involves a kernel crash.  It looks like an issue with UHCI or the USB
audio driver.

I suspect it might be the audio driver, as someone on the alsa mailing
list suggested the USB sound driver can't handle when one isochronous
buffer in an URB has an error, but the URB status is 0.  I think Pierre
is running with the latest alsa code, which perhaps triggers the crash?

But I'm not an alsa or a USB sound expert, so could Jaroslav, Takashi,
or Clemens look at this issue?

Attached is Pierre's dmesg from the original crash, along with lsusb
output.  Note that the patch below is supposed to be against
sound/usb/urb.c.

Subject: [PATCH] ALSA: usb - prevent kernel panic on disconnect

Fix 100% reproducible kernel panic when a USB audio device is
disconnected during playback. When the PCM substream is NULL, any
dereference causes a kernel panic. This isn't a recent problem, the crash
happened with a 2.6.35 kernel as well

Note that this is only a work-around, it does not address the
root cause of this inconsistency between urbs and PCM states. The
dmesg below shows two calls to snd_urb_complete, the substream is
NULL and the state is either running or stopped. This doesn't make
any sense.

Thanks to Sarah Sharp <sarah.a.sharp-VuQAYsv1563Yd54FQh9/CA@public.gmane.org> for her
help.

I'd guess the audio driver, because that's where the crash occurs.

I don't think that can happen.  The URB status won't be 0 unless all 
the individual buffers have 0 status.

It's most likely a matter of the device being disconnected but the
device file still being open.  Perhaps not everything gets cleaned up
the way it should when that happens.

Clemens is the best person to fix this.

In any case, the driver would then just copy garbage samples out of the
buffer; this wouldn't affect the driver's data structures.

subs->pcm_substream == NULL happens only when the device file _has_
been closed.

There seems to be a race between snd_usb_pcm_close() and
snd_usb_stream_disconnect().  I think a mutex taken by both functions
should fix this; and all functions that check 'shutdown' probably need
serializing.

More exactly, it's cleared the PCM close callback, so during it's
being closed :)
Looks like a race as you mentioned below, indeed.

Or, rather make sure that snd_usb_release_substreams() is finished
before PCM close; actually it should be called in hw_free callback,
but currently it's skipped by the shutdown flag check.  I guess this
check isn't right.

The serialization of shutdown check is a good point, but this won't
hit actual bugs, I suppose.

Ok.  I don't have the audio expertise to make a patch; can you or
Clemens make one for Pierre to try out?

Well, a simple one like the follow is good to check at first.
If this works, it's indeed a race between disconnect callback and PCM
close (hw_free is always called before close).

We can refine it in a better form later once after it's confirmed :)

ALSA: usb-audio: fix oops due to cleanup race when disconnecting

[Clemens Ladisch]

From: Takashi Iwai <tiwai-l3A5Bk7waGM@public.gmane.org>

When a USB audio device is disconnected, snd_usb_audio_disconnect()
kills all audio URBs.  At the same time, the application, after being
notified of the disconnection, might close the device, in which case
ALSA calls the .hw_free callback, which should free the URBs too.

Commit de1b8b93a0ba prevented snd_usb_hw_free() from freeing the URBs to
avoid a hang that resulted from this race, but this introduced another
race because the URB callbacks could now be executed after
snd_usb_hw_free() has returned, and try to access already freed data.

Fix the first race by introducing a mutex to serialize the disconnect
callback and all PCM callbacks that manage URBs (hw_free and hw_params).

Doesn't work for me. same oops as before. Either I made a mistake when
merging this patch manually (there were some rejects), or the problem
is still there.

Which kernel version were you trying to patch?  Was it a vanilla kernel,
or did you have some other changes applied?

Added some additional traces, the dereference takes place before the
mutex is unlocked.

Discard my other messages, the patch seems to work fine when I don't
skip any steps...  I need more coffee and stop multitasking... I spent
15mn pluging and unpluging my headset without any issues.
Thanks Takashi and Clemens for the fix

Hmm.  Is snd_usb_release_substream_urbs() is called properly before
these errors?  Is force=1 set?

Also, in your log, it shows subs->running = 0.  So, there is no
NULL dereference.  But, it's still strange since all active URLs
must have been killed beforehand in deactivate_urbs() and the
succeeding call of wait_clear_urbs()...

OK, I committed the patch to sound git tree now.
Thanks for testing!
