Hi!
Since alsa-lib commit dec428c352217010e4b8bd750d302b8062339d32, I've
occationally been hit by an EBADFD whenever any program tries to play
sound. The situation I get is that the first shmget succeds, so
dmix->shmid >= 0, therefore first_instance = 0.
But buf.shm_nattach = 1, so before the commit shmptr would have been
zeroed out, but isn't anymore. And since I still have:
dmix->shmptr->magic == SND_PCM_DIRECT_MAGIC, I don't get EINVAL, but
EBADFD, somewhere down the line.
>From what I understand, the race condition that was fixed would still
be avoided if shmptr was zeroed on (first_instance || buf.shm_nattch == 1).
If that is the case, would you please consider applying attached diff?
Regards,
Lars Lindqvist

I wonder how does this succeed? It's a leftover shmem?
But then why it contains the garbage...?

Could you give which line actually gives EBADFD?

This may work, but I still would like to see how another unexpected
situation happens.

I seem to be able to trigger it by having one client open, starting another,
and quickly closing the first one. I'm not sufficiently familiar with the
alsa source, but I would guess that shmget succeeds since someone is already
attached, and then the shmem gets deconstructed when the first one closes.
Leaving it in a bad state for the second client. So a new type of race
situation is possible.
However, in this scenario, if I just stop playback or kill the processes,
on the next startup of an alsa-lib user everything is fine again. So
first_instance == 1 and buf.shm_nattch == 1.
This is in contrast to the occational problem I've been having, that I don't
know exactly how to trigger, where shmget apparently always succeeds, giving
first_instace == 0 and buf.shm_nattch == 1. Which I've only been able to
fix by completely resetting the driver by rmmod + modprobe.

In the case where I can trigger it by will, it is from pcm_dmix.c:1074, where
snd_pcm_open_slave returns -EBADFD.
But I don't know where it comes from in the spontaneous, more persistent,
case. I'm sure it is not the same place, since SNDERR("unable to open slave")
is run when snd_pcm_open_slave() < 0, but I get no such message in this case.
I'll try to pinpoint it the next chance I get.

One possible case is that the second stream is opened almost at the
same time as the first stream, and the second stream reaches to the
point checking SND_PCM_DIRECT_MAGIC before the first one finishes the
initialization. Does a hackish patch like below make any difference?

No it doesn't, the magic check succeeds. The situation is that the first
one has been open for "a long time" when I open the second one. So I
would think that initialization has been completed properly. If the
second one opens just as the first closes, it might be that the second
assigns (correctly) first_instance = 0, but by the time it reaches the
"if (first_instance)" check, the first one has closed, and left garbage.

Actually we have a semaphore before shm access, so the race at two
opens shouldn't happen. I noticed it after I sent my previous mail.
But the semaphore is taken also at snd_pcm_dmix_close(). So I wonder
where the race actually happens. Both open and close must be
protected while another stream is opening or closing.
Could you try to check where you get the exact error...?

The execution tree, as far as I can find is the following:
snd_pcm_dmix_open:
* Line 1009 snd_pcm_direct_shm_create_or_connect with the code in question,
* which returns 0. So we end up in line 1058, dmix->shmtr->use_server is 0,
* so go to line 1072.. running:
snd_pcm_open_slave, running:
snd_pcm_open_named_slave, running:
snd_pcm_open_conf
* where snd_dlobj_cache_get gives open_func = snd_pcm_hw_open, so
snd_pcm_hw_open()
snd_open_device("/dev/snd/pcmC0D0p")
* where open() returns -1 with errno = EBADFD

OK, then the question is why other stream could be closed while this
is being opened and protected via semaphore. Maybe the semaphore
protection isn't perfect?
In anyway, in such a case, we may retry opening the stream as the
first element. This is safer than blindly assuming the first element
via nattach value (which is racy). An untested patch is below.
thanks,
Takashi

Yes, this seems to work. I'm at least not able to trigger the problem
myself anymore. I'll use this for a few days, and report back if I
happen to get any unexpected EBADFDs.

OK, I now applied the fix to git tree. Let's see whether this works
stably enough. Let me know if you still see a similar problem with
it.
