<content type='text'>
A deadlock can be initiated by userspace via ioctl(SNDCTL_SEQ_OUTOFBAND)
on /dev/sequencer with TMR_ECHO midi event.

In this case the control flow is:
sound_ioctl()
-&gt; case SND_DEV_SEQ:
   case SND_DEV_SEQ2:
     sequencer_ioctl()
     -&gt; case SNDCTL_SEQ_OUTOFBAND:
          spin_lock_irqsave(&amp;lock,flags);
          play_event();
          -&gt; case EV_TIMING:
               seq_timing_event()
               -&gt; case TMR_ECHO:
                    seq_copy_to_input()
                    -&gt; spin_lock_irqsave(&amp;lock,flags);

It seems that spin_lock_irqsave() around play_event() is not necessary,
because the only other call location in seq_startplay() makes the call
without acquiring spinlock.

So, the patch just removes spinlocks around play_event().
By the way, it removes unreachable code in seq_timing_event(),
since (seq_mode == SEQ_2) case is handled in the beginning.

Compile tested only.

<title>ALSA: control: Fix replacing user controls</title>

(commit 82262a46627bebb0febcc26664746c25cef08563 upstream)

There are two issues with the current implementation for replacing user
controls. The first is that the code does not check if the control is actually a
user control and neither does it check if the control is owned by the process
that tries to remove it. That allows userspace applications to remove arbitrary
controls, which can cause a user after free if a for example a driver does not
expect a control to be removed from under its feed.

The second issue is that on one hand when a control is replaced the
user_ctl_count limit is not checked and on the other hand the user_ctl_count is
increased (even though the number of user controls does not change). This allows
userspace, once the user_ctl_count limit as been reached, to repeatedly replace
a control until user_ctl_count overflows. Once that happens new controls can be
added effectively bypassing the user_ctl_count limit.

Both issues can be fixed by instead of open-coding the removal of the control
that is to be replaced to use snd_ctl_remove_user_ctl(). This function does
proper permission checks as well as decrements user_ctl_count after the control
has been removed.

Note that by using snd_ctl_remove_user_ctl() the check which returns -EBUSY at
beginning of the function if the control already exists is removed. This is not
a problem though since the check is quite useless, because the lock that is
protecting the control list is released between the check and before adding the
new control to the list, which means that it is possible that a different
control with the same settings is added to the list after the check. Luckily
there is another check that is done while holding the lock in snd_ctl_add(), so
we'll rely on that to make sure that the same control is not added twice.

A control that is visible on the card-&gt;controls list can be freed at any time.
This means we must not access any of its memory while not holding the
controls_rw_lock. Otherwise we risk a use after free access.

[ Upstream commit 07f4d9d74a04aa7c72c5dae0ef97565f28f17b92 ]

The user-control put and get handlers as well as the tlv do not protect against
concurrent access from multiple threads. Since the state of the control is not
updated atomically it is possible that either two write operations or a write
and a read operation race against each other. Both can lead to arbitrary memory
disclosure. This patch introduces a new lock that protects user-controls from
concurrent access. Since applications typically access controls sequentially
than in parallel a single lock per card should be fine.

<title>ALSA: control: Handle numid overflow</title>

Each control gets automatically assigned its numids when the control is created.
The allocation is done by incrementing the numid by the amount of allocated
numids per allocation. This means that excessive creation and destruction of
controls (e.g. via SNDRV_CTL_IOCTL_ELEM_ADD/REMOVE) can cause the id to
eventually overflow. Currently when this happens for the control that caused the
overflow kctl-&gt;id.numid + kctl-&gt;count will also over flow causing it to be
smaller than kctl-&gt;id.numid. Most of the code assumes that this is something
that can not happen, so we need to make sure that it won't happen

The ALSA control code expects that the range of assigned indices to a control is
continuous and does not overflow. Currently there are no checks to enforce this.
If a control with a overflowing index range is created that control becomes
effectively inaccessible and unremovable since snd_ctl_find_id() will not be
able to find it. This patch adds a check that makes sure that controls with a
overflowing index range can not be created.

commit 66efdc71d95887b652a742a5dae51fa834d71465 upstream.

snd_seq_timer_open() didn't catch the whole error path but let through
if the timer id is a slave.  This may lead to Oops by accessing the
uninitialized pointer.

commit 66efdc71d95887b652a742a5dae51fa834d71465 upstream.

snd_seq_timer_open() didn't catch the whole error path but let through
if the timer id is a slave.  This may lead to Oops by accessing the
uninitialized pointer.

FSC Amilo Pi 1505 has a buggy BIOS and doesn't set up the HP and
speaker pins properly.  Add the pinfix entry for that.

[2.6.32: additional background from Jonathan below]
&gt; Hi Willy,
&gt;
&gt; Please consider
&gt;
&gt;   cfc9b06f0bef ALSA: hda - Add a pin-fix for FSC Amilo Pi1505
&gt;
&gt; for application to the 2.6.32.y tree.  Without this patch, the Amilo
&gt; Pi 1505's internal speaker is silent unless a jack is plugged into its
&gt; headphone jack.
&gt;
&gt; Jose Manuel Castroagudin noticed[1] that 2.6.30 is not affected, so
&gt; this seems to be a regression.
&gt;
&gt; The patch was applied upstream during the 2.6.33 merge window, where
&gt; it worked.  That said, I didn't manage to track down anyone with a
&gt; Pi1505 to test it against 2.6.32, so thoughts from alsa folks on
&gt; whether this is appropriate for 2.6.32.y would be useful.
&gt;
&gt; Hope that helps,
&gt; Jonathan
&gt;

1. Add more ASUS NB model.
2. Fixed alc663_m51va_setup
   M51VA has Digital Mic that NID is 0x12. The record source index is
   0x9 for ALC663.
   So, to modify the alc663_m51va_setup function to index 0x9
   and add analog Mic aupport function alc663_mode1_setup.
3. Add ASUS mode7 and mode8 modules for ALC663
