[ Upstream commit f1fae475f10a26b7e34da4ff2e2f19b7feb3548e ]
i2sbus_add_dev() is supposed to return the number of probed devices,
i.e. either 1 or 0. However, i2sbus_add_dev() has one error handling
that returns -ENODEV; this will screw up the accumulation number
counted in the caller, i2sbus_probe().
Fix the return value to 0 and add the comment for better understanding
for readers.

commit ee03c0f200eb0d9f22dd8732d9fb7956d91019c2 upstream.
With char becoming unsigned by default, and with `char` alone being
ambiguous and based on architecture, signed chars need to be marked
explicitly as such. This fixes warnings like:
sound/pci/au88x0/au88x0_core.c:2029 vortex_adb_checkinout() warn: signedness bug returning '(-22)'
sound/pci/au88x0/au88x0_core.c:2046 vortex_adb_checkinout() warn: signedness bug returning '(-12)'
sound/pci/au88x0/au88x0_core.c:2125 vortex_adb_allocroute() warn: 'vortex_adb_checkinout(vortex, (0), en, 0)' is unsigned
sound/pci/au88x0/au88x0_core.c:2170 vortex_adb_allocroute() warn: 'vortex_adb_checkinout(vortex, stream->resources, en, 4)' is unsigned
As well, since one function returns errnos, return an `int` rather than
a `signed char`.

commit f0a868788fcbf63cdab51f5adcf73b271ede8164 upstream.
The current code for freeing the emux timer is extremely dangerous:
CPU0 CPU1
---- ----
snd_emux_timer_callback()
snd_emux_free()
spin_lock(&emu->voice_lock)
del_timer(&emu->tlist); <-- returns immediately
spin_unlock(&emu->voice_lock);
[..]
kfree(emu);
spin_lock(&emu->voice_lock);
[BOOM!]
Instead just use del_timer_sync() which will wait for the timer to finish
before continuing. No need to check if the timer is active or not when
doing so.
This doesn't fix the race of a possible re-arming of the timer, but at
least it won't use the data that has just been freed.

commit 6382da0828995af87aa8b8bef28cc61aceb4aff3 upstream.
When the driver hits -ENOMEM at allocating a URB or a buffer, it
aborts and goes to the error path that releases the all previously
allocated resources. However, when -ENOMEM hits at the middle of the
sync EP URB allocation loop, the partially allocated URBs might be
left without released, because ep->nurbs is still zero at that point.
Fix it by setting ep->nurbs at first, so that the error handler loops
over the full URB list.

commit a70aef7982b012e86dfd39fbb235e76a21ae778a upstream.
The register_mutex taken around the dev_unregister callback call in
snd_rawmidi_free() may potentially lead to a mutex deadlock, when OSS
emulation and a hot unplug are involved.
Since the mutex doesn't protect the actual race (as the registration
itself is already protected by another means), let's drop it.

commit 97d917879d7f92df09c3f21fd54609a8bcd654b2 upstream.
We took sound_oss_mutex around the calls of unregister_sound_special()
at unregistering OSS devices. This may, however, lead to a deadlock,
because we manage the card release via the card's device object, and
the release may happen at unregister_sound_special() call -- which
will take sound_oss_mutex again in turn.
Although the deadlock might be fixed by relaxing the rawmidi mutex in
the previous commit, it's safer to move unregister_sound_special()
calls themselves out of the sound_oss_mutex, too. The call is
race-safe as the function has a spinlock protection by itself.

Hans reported that his Sony VAIO VPX11S1E showed the broken sound

that the position reporting is inaccurate, and very likely hitting on

The patch applies the workaround for Poulsbo generically to switch to

commit d29f59051d3a07b81281b2df2b8c9dfe4716067f upstream.
The voice allocator sometimes begins allocating from near the end of the
array and then wraps around, however snd_emu10k1_pcm_channel_alloc()
accesses the newly allocated voices as if it never wrapped around.
This results in out of bounds access if the first voice has a high enough
index so that first_voice + requested_voice_count > NUM_G (64).
The more voices are requested, the more likely it is for this to occur.
This was initially discovered using PipeWire, however it can be reproduced
by calling aplay multiple times with 16 channels:
aplay -r 48000 -D plughw:CARD=Live,DEV=3 -c 16 /dev/zero

commit 3e7e04b747adea36f349715d9f0998eeebf15d72 upstream.
It's been reported that there is a possible data-race accessing to the
global card_requested[] array at ALSA sequencer core, which is used
for determining whether to call request_module() for the card or not.
This data race itself is almost harmless, as it might end up with one
extra request_module() call for the already loaded module at most.
But it's still better to fix.
This patch addresses the possible data race of card_requested[] and
client_requested[] arrays by replacing them with bitmask.
It's an atomic operation and can work without locks.

commit 22dec134dbfa825b963f8a1807ad19b943e46a56 upstream.
ALSA OSS sequencer refers to a global variable max_midi_devs at
creating a new port, storing it to its own field. Meanwhile this
variable may be changed by other sequencer events at
snd_seq_oss_midi_check_exit_port() in parallel, which may cause a data
race.
OTOH, this data race itself is almost harmless, as the access to the
MIDI device is done via get_mdev() and it's protected with a refcount,
hence its presence is guaranteed.
Though, it's sill better to address the data-race from the code sanity
POV, and this patch adds the proper spinlock for the protection.

Currently the call of kill_fasync() from an interrupt handler might
lead to potential spin deadlocks, as spotted by syzkaller.
Unfortunately, it's not so trivial to fix this lock chain as it's
involved with the tasklist_lock that is touched in allover places.
As a temporary workaround, this patch provides the way to defer the
async signal notification in a work. The new helper functions,
snd_fasync_helper() and snd_kill_faync() are replacements for
fasync_helper() and kill_fasync(), respectively. In addition,
snd_fasync_free() needs to be called at the destructor of the relevant
file object.

As i2c_add_driver could return error if fails, it should be
better to check the return value.
However, if the CONFIG_I2C and CONFIG_SPI_MASTER are both true,
the return value of i2c_add_driver will be covered by
spi_register_driver.
Therefore, it is necessary to add check and return error if fails.

When the driver fails in snd_card_register() at probe time, it will free
the 'bcd2k->midi_out_urb' before killing it, which may cause a UAF bug.

commit 5c1733e33c888a3cb7f576564d8ad543d5ad4a9e upstream.
Currently the standard memory allocator (snd_dma_malloc_pages*())
passes the byte size to allocate as is. Most of the backends
allocates real pages, hence the actual allocations are aligned in page
size. However, the genalloc doesn't seem assuring the size alignment,
hence it may result in the access outside the buffer when the whole
memory pages are exposed via mmap.
For avoiding such inconsistencies, this patch makes the allocation
size always to be aligned in page size.
Note that, after this change, snd_dma_buffer.bytes field contains the
aligned size, not the originally requested size. This value is also
used for releasing the pages in return.

Put the SGTL5000 in a silent/safe state on shutdown/remove, this is
required since the SGTL5000 produces a constant noise on its output
after it is configured and its clock is removed. Without this change
this is happening every time the module is unbound/removed or from
reboot till the clock is enabled again.
The issue was experienced on both a Toradex Colibri/Apalis iMX6, but can
be easily reproduced everywhere just playing something on the codec and
after that removing/unbinding the driver.

commit 5faa0bc69102f3a4c605581564c367be5eb94dfa upstream.
Currently the Conexant codec driver sets up the beep NID after calling
snd_hda_gen_parse_auto_config(). It turned out that this results in
the insufficient setup for the beep control, as the generic parser
handles the fake path in snd_hda_gen_parse_auto_config() only if the
beep_nid is set up beforehand.
For dealing with the beep widget properly, call cx_auto_parse_beep()
before snd_hda_gen_parse_auto_config() call.
