7be34f6fee ALSA: ump: Fix evaluation of MIDI 1.0 FB info
The m1.0 field of UMP Function Block info specifies whether the given
FB is a MIDI 1.0 port or not.  When implementing the UMP support on
Linux, I somehow interpreted as if it were bit flags, but the field is
actually an enumeration from 0 to 2, where 2 means MIDI 1.0 *and* low
speed.

This patch corrects the interpretation and sets the right bit flags
depending on the m1.0 field of FB Info.  This effectively fixes the
missing detection of MIDI 1.0 FB when m1.0 is 2.

20c0c49720 ALSA: rawmidi: Fix kvfree() call in spinlock
At the conversion of locking with guard(), I overlooked that kvfree()
must not be called inside the spinlock unlike kfree(), and this was
caught by syzkaller now.

This patch reverts the conversion partially for restoring the kvfree()
call outside the spinlock.  It's not trivial to use guard() in this
context, unfortunately.

c2d188e137 ALSA: ump: Don't enumeration invalid groups for legacy rawmidi
The legacy rawmidi tries to enumerate all possible UMP groups
belonging to the UMP endpoint.  But currently it shows all 16 ports
when the UMP endpoint is configured with static blocks, although most
of them may be unused.

There was already a fix for the sequencer client side to ignore such
groups in the commit 3bfd7c0ba1 ("ALSA: seq: ump: Skip useless ports
for static blocks"), and this commit is a similar fix for UMP
rawmidi devices; it adds simply the check for the validity of each
group that has been already parsed.  (Note that the group info was
moved to snd_ump_endpoint.groups[] by the commit 0642a3c5ca
("ALSA: ump: Update substream name from assigned FB names")).

and allows for the serialization of operations.

a04dae6fa4 ALSA: silence integer wrapping warning
This patch doesn't change runtime at all, it's just for kernel hardening.

The "count" here comes from the user and on 32bit systems, it leads to
integer wrapping when we pass it to compute_user_elem_size():

	alloc_size = compute_user_elem_size(private_size, count);

However, the integer over is harmless because later "count" is checked
when we pass it to snd_ctl_new():

	err = snd_ctl_new(&kctl, count, access, file);

These days as part of kernel hardening we're trying to avoid integer
overflows when they affect size_t type.  So to avoid the integer overflow
copy the check from snd_ctl_new() and do it at the start of the
snd_ctl_elem_add() function as well.

cb787f4ac0 [tree-wide] finally take no_llseek out
no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

0b9f2bd00f ALSA: memalloc: Use proper DMA mapping API for x86 S/G buffer allocations
The fallback S/G buffer allocation for x86 used the addresses deduced
from the page allocations blindly.  It broke the allocations on IOMMU
and made us to work around with a hackish DMA ops check.

For cleaning up those messes, this patch switches to the proper DMA
mapping API usages with the standard sg-table instead.

By introducing the sg-table, the address table isn't needed, but for
keeping the original allocation sizes for freeing, replace it with the
array keeping the number of pages.

The get_addr callback is changed to use the existing one for
non-contiguous buffers.  (Also it's the reason sg_table is put at the
beginning of struct snd_dma_sg_fallback.)

And finally, the hackish workaround that checks the DMA ops is
dropped now.

use the standard DMA code primarily and the fallback is applied only
limitedly.  This made the Xen PV specific workarounds we took in the
commit 53466ebdec ("ALSA: memalloc: Workaround for Xen PV") rather
superfluous.

It was a hackish workaround for the regression at that time, and it
seems that it's causing another issues (reportedly memory
corruptions).  So it's better to clean it up, after all.

5ced8b914e ALSA: memalloc: Move snd_malloc_ops definition into memalloc.c again
The definition of struct snd_malloc_ops was moved out to
memalloc_local.h since there was another code for S/G buffer
allocation referring to the struct.  But since the code change to use
non-contiguous allocators, it's solely referred in memalloc.c, hence
it makes little sense to have a separate header file.

Let's move it back to memalloc.c.

090624b7dc ALSA: pcm: add more sample rate definitions
This adds a sample rate definition for 12kHz, 24kHz and 128kHz.

Admittedly, just a few drivers are currently using these sample
rates but there is enough of a recurrence to justify adding a definition
for them and remove some custom rate constraint code while at it.

The new definitions are not added to the interval definitions, such as
SNDRV_PCM_RATE_8000_44100, because it would silently add new supported
rates to drivers that may or may not support them. For sure the drivers
have not been tested for these new rates so it is better to leave them out
of interval definitions.

That being said, the added rates are multiples of well know rates families,
it is very likely that a lot of devices out there actually supports them.

40a024b81d ALSA: core: Drop superfluous no_free_ptr() for memdup_user() errors
We used to wrap with no_free_ptr() for the return value from
memdup_user() with errors where the auto cleanup is applied.  This was
a workaround because the initial implementation of kfree auto-cleanup
checked only NULL pointers.

Since recently, though, the kfree auto-cleanup checks with
IS_ERR_OR_NULL() (by the commit cd7eb8f83f ("mm/slab: make
__free(kfree) accept error pointers")), hence those workarounds became
superfluous.  Let's drop them now.

37745918e0 ALSA: timer: Introduce virtual userspace-driven timers
Implement two ioctl calls in order to support virtual userspace-driven
ALSA timers.

The first ioctl is SNDRV_TIMER_IOCTL_CREATE, which gets the
snd_timer_uinfo struct as a parameter and puts a file descriptor of a
virtual timer into the `fd` field of the snd_timer_unfo structure. It
also updates the `id` field of the snd_timer_uinfo struct, which
provides a unique identifier for the timer (basically, the subdevice
number which can be used when creating timer instances).

This patch also introduces a tiny id allocator for the userspace-driven
timers, which guarantees that we don't have more than 128 of them in the
system.

Another ioctl is SNDRV_TIMER_IOCTL_TRIGGER, which allows us to trigger
the virtual timer (and calls snd_timer_interrupt for the timer under
the hood), causing all of the timer instances binded to this timer to
execute their callbacks.

The maximum amount of ticks available for the timer is 1 for the sake of
simplicity of the userspace API. 'start', 'stop', 'open' and 'close'
callbacks for the userspace-driven timers are empty since we don't
really do any hardware initialization here.

1da91ea87a introduce fd_file(), convert all accessors to it.
For any changes of struct fd representation we need to
turn existing accesses to fields into calls of wrappers.
Accesses to struct fd::flags are very few (3 in linux/file.h,
1 in net/socket.c, 3 in fs/overlayfs/file.c and 3 more in
explicit initializers).
	Those can be dealt with in the commit converting to
new layout; accesses to struct fd::file are too many for that.
	This commit converts (almost) all of f.file to
fd_file(f).  It's not entirely mechanical ('file' is used as
a member name more than just in struct fd) and it does not
even attempt to distinguish the uses in pointer context from
those in boolean context; the latter will be eventually turned
into a separate helper (fd_empty()).

	NOTE: mass conversion to fd_empty(), tempting as it
might be, is a bad idea; better do that piecewise in commit
that convert from fdget...() to CLASS(...).

The recent addition of a sanity check for a too low start tick time

38ea4c3dc3 ALSA: control: Optimize locking for look-up
For a fast look-up of a control element via either numid or name
matching (enabled via CONFIG_SND_CTL_FAST_LOOKUP), a locking isn't
needed at all thanks to Xarray.  OTOH, the locking is still needed for
a slow linked-list traversal, and that's rather a rare case.

In this patch, we reduce the use of locking at snd_ctl_find_*() API
functions, and switch from controls_rwsem to controls_rwlock for
avoiding unnecessary lock inversions.  This also resulted in a nice
cleanup, as *_unlocked() version of snd_ctl_find_*() APIs can be
dropped.

snd_ctl_find_id_mixer_unlocked() is still left just as an alias of
snd_ctl_find_id_mixer(), since soc-card.c has a wrapper and there are
several users.  Once after converting there, we can remove it later.
