syzkaller reported an invalid access in PCM OSS read, and this seems
to be an overflow of the internal buffer allocated for a plugin.
Since the rate plugin adjusts its transfer size dynamically, the
calculation for the chained plugin might be bigger than the given
buffer size in some extreme cases, which lead to such an buffer
overflow as caught by KASAN.
Fix it by limiting the max transfer size properly by checking against
the destination size in each plugin transfer callback.

The commit 609f548534 ("ALSA: hda: hdmi - preserve non-MST PCM
routing for Intel platforms") tried to restore the old behavior wrt
assignment of the PCM slot for Intel platforms, but this didn't do it
right. As found in the later discussion, a positive pipe id on Intel
platforms can be passed for single monitor attachment case.
This patch reverts the previous attempt and applies a simpler
workaround instead. Actually, for Intel platforms, we can handle as
if per_pin->dev_id=0, assign the primary slot at the first try. This
assures the compatible behavior with the previous versions regarding
the slot assignment.

The recent commit in HD-audio stream management for changing the
stripe control seems causing a regression on some platforms. The
stripe control is currently used only by HDMI codec, and applying the
stripe mask unconditionally may lead to scratchy and static noises as
seen on some MacBooks.
For addressing the regression, this patch changes the stream
management code to apply the stripe mask conditionally only when the
codec driver requested.

As part of the cleanup of some remaining y2038 issues, I came to

In completely unrelated work, I spent time on cleaning up parts of this

After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the rest

This series incorporates some of Al's work and many patches of my own,

the scsi ioctl handlers. I have patches for those as well, but they need

The auto-parser assigns the bass speaker to DAC3 (NID 0x06) which
is without the volume control. I do not see a reason to use DAC2,
because the shared output to all speakers produces the sufficient
and well balanced sound. The stereo support is enough for this
purpose (laptop).

Commit 5398e94fb7 ("ALSA: hda - Add DP-MST support for NVIDIA codecs")
introduced a slight change of behaviour how non-MST monitors are
assigned to PCMs on Intel platforms.
In the drm_audio_component.h interface, the third parameter
to pin_eld_notify() is pipe number. On Intel platforms, this value
is -1 for MST. On other platforms, a non-zero pipe id is used to
signal MST use.
This difference leads to some subtle differences in hdmi_find_pcm_slot()
with regards to how non-MST monitors are assigned to PCMs.
This patch restores the original behaviour on Intel platforms while
keeping the new allocation policy on other platforms.

Add additional check in hdmi_find_pcm_slot() to not return
a pcm index that points to unallocated pcm. This could happen
if codec driver is set up in codec->mst_no_extra_pcms mode.
On some platforms, this leads to a kernel oops in snd_ctl_notify(),
called via update_eld().

We've added the bass speaker support on Acer 8951G by the commit
00066e9733 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems
that the GPIO pin was wrongly set: while the commit turns off the bit
to power up the amp, the actual hardware reacts other way round,
i.e. GPIO bit on = amp on.
So this patch fixes the bug, turning on the GPIO bit 0x02 as default.
Since turning on the GPIO bit can be more easily managed with
alc_setup_gpio() call, we simplify the quirk code by integrating the
GPIO setup into the existing alc662_fixup_aspire_ethos_hp() and
dropping the whole ALC669_FIXUP_ACER_ASPIRE_ETHOS_SUBWOOFER quirk.

Fix regression in how intel_haswell_fixup_connect_list()
results are used in hda_read_pin_conn(). Use of
snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses
the cache and thus also bypasses the overridden pin connection
list. On platforms that require the connection list fixup,
mux list will be empty and HDMI playback will fail to -EBUSY
at open.
Fix the regression in hda_read_pinn_conn(). Simplify code
as suggested by Takashi Iwai to remove old
intel_haswell_fixup_connect_list() and copy the cvt_nid list

Static analysis tools (cppcheck and PVS Studio) report an error
in loopback_snd_timer_period_elapsed() regarding dpcm_play pointer
dereference earlier than its null-check. And although this is a result
of a formal check, and the pointer correctness is also protected
by having a corresponding bit set in the "running" mask, re-ordering
of the lines can imake the code even formally correct and eliminate
those static analysis error reports.

There have been some significant changes in the core side, both for
ALSA and ASoC, while lots of development have been seen in SOF, as
well as many small fixes/improvements for ASoC codecs and platforms.
Below is a highlight in this cycle:
Core:
- The unification of PCM vmalloc buffer allocation helpers into the
standard API
- Clean up of the default PCM mmap handling for vmalloc & SG-buffer
- Fix potential races at ALSA timer open
- A few new PCM API extensions; just preliminary core changes, the
actual changes in drivers will be merged in 5.6
- Continued ASoC componentization works; now almost everything is a
common ASoC component object. A lot of refactoring and
simplification have been done along with it.
ASoC:
- Many fixes to the Sound Open Firmware (SOF) code
- Wake on voice support for Chromebooks
- SPI support and trigger word detection for RT5677
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
HD-audio:
- Improved Intel DSP configuration / probe code for SOF
- Plumbing the legacy HD-audio driver with Intel SOF HDMI
- DP-MST support for Nvidia HDMI codecs
- Realtek quirks cleanups and new additions as usual
Others:
- Lots of refactoring and cleanups for FireWire; period-size sharing,
h/w IRQ interval configuration, clock recovery improvements, etc
- USB-audio: Scarlett mixer quirks
- Cleanups of PCM calls in various drivers (including media and USB)
to adapt the core API changes

Lots of stuff going on in the core for SPI this time around, the two big
changes both being around time in different forms:
- A rework of delay times from Alexandru Ardelean which makes the ways
in which they are specified more consistent between drivers so that
what's available to clients is less dependent on the hardware
implementation.
- Support for PTP timestamping of transfers from Vladimir Oltean,
useful for use with precision clocks with SPI control interfaces.
- Big cleanups for the Atmel, PXA2xx and Zynq QSPI drivers.

loopback_parse_timer_id() uses snd_card_ref(), that can lock on mutex,
also snd_timer_instance_new() uses non-atomic allocation, that can sleep.
So, both functions can not be called from loopback_snd_timer_open()
with cable->lock spinlock locked.
Moreover, most part of loopback_snd_timer_open() function body works
when the opposite stream of the same cable does not yet exist, and
the current stream is not yet completely open and can't be running,
so existing locking of loopback->cable_lock mutex is enough to protect
from conflicts with simultaneous opening or closing.
Locking of cable->lock spinlock is not needed in this case.

The old Nvidia chips have multiple HD-audio codecs on the same
HD-audio controller, and this doesn't work as expected with the current
audio component binding that is implemented under the one-codec-per-
controller assumption; at the probe time, the driver leads to several
kernel WARNING messages.
For the proper support, we may change the pin2port and port2pin to
traverse the codec list per the given pin number, but this needs more
development and testing.
As a quick workaround, instead, this patch drops the binding in the
audio side for these legacy chips since the audio component support in
nouveau graphics driver is still not merged (hence it's basically
unused).

Many PCI and other drivers performs snd_pcm_period_elapsed() simply in
its interrupt handler, so the sync_stop operation is just to call
synchronize_irq(). Instead of putting this call multiple times,
introduce the common card->sync_irq field. When this field is set,
PCM core performs synchronize_irq() for sync-stop operation. Each
driver just needs to copy its local IRQ number to card->sync_irq, and
that's all we need.

The standard programming model of a PCM sound driver is to process
snd_pcm_period_elapsed() from an interrupt handler. When a running
stream is stopped, PCM core calls the trigger-STOP PCM ops, sets the
stream state to SETUP, and moves on to the next step. This is
performed in an atomic manner -- this could be called from the interrupt
context, after all.
The problem is that, if the stream goes further and reaches to the
CLOSE state immediately, the stream might be still being processed in
snd_pcm_period_elapsed() in the interrupt context, and hits a NULL
dereference. Such a crash happens because of the atomic operation,
and we can't wait until the stream-stop finishes.
For addressing such a problem, this commit adds a new PCM ops,
sync_stop. This gets called at the appropriate places that need a
sync with the stream-stop, i.e. at hw_params, prepare and hw_free.
Some drivers already have a similar mechanism implemented locally, and
we'll refactor the code later.

This patch adds the support for the feature to automatically allocate
and free PCM buffers, so called "managed buffer allocation" mode.
It's set up via new PCM helpers, snd_pcm_set_managed_buffer() and
snd_pcm_set_managed_buffer_all(), both of which correspond to the
existing preallocator helpers, snd_pcm_lib_preallocate_pages() and
snd_pcm_lib_preallocate_pages_for_all(). When the new helper is used,
it not only performs the pre-allocation of buffers, but also it
manages to call snd_pcm_lib_malloc_pages() before the PCM hw_params
ops and snd_lib_pcm_free() after the PCM hw_free ops inside PCM core,
respectively. This allows drivers to drop the explicit calls of the
memory allocation / release functions, and it will be a good amount of
code reduction in the end of this patch series.
When the PCM substream is set to the managed buffer allocation mode,
the managed_buffer_alloc flag is set in the substream object. Since
some drivers want to know when a buffer is newly allocated or
re-allocated at hw_params callback (e.g. want to set up the additional
stuff for the given buffer only at allocation time), now PCM core
turns on buffer_changed flag when the buffer has changed.
The standard conversions to use the new API will be straightforward:
- Replace snd_pcm_lib_preallocate*() calls with the corresponding
snd_pcm_set_managed_buffer*(); the arguments should be unchanged
- Drop superfluous snd_pcm_lib_malloc() and snd_pcm_lib_free() calls;
the check of snd_pcm_lib_malloc() returns should be replaced with
the check of runtime->buffer_changed flag.
- If hw_params or hw_free becomes empty, drop them from PCM ops

Show and change sound card timer source with read-write info
file in proc filesystem. Initial string can still be set as
module parameter.
The timer source string value can be changed at any time,
but it is latched by PCM substream open callback (the first one
for a particular cable). At this point it is actually used, that
is the string is parsed, and the timer is looked up and opened.
The timer source is set for a loopback card (the same as initial
setting by module parameter), but every cable uses the value,
current at the moment of open.
Setting the value to empty string switches the timer to jiffies.

to do synchronous audio forwarding between hardware sound card and aloop
devices. Such an audio route could look like the following:
Sound card -> Loopback application -> ALSA loop device -> arecord
In this case the loopback device should use the sound timer of the sound
card. Without this patch the loopback application has to implement an
adaptive sample rate converter to align the different clocks of the
different ALSA devices.
The used timer can be selected by referring to a sound card, its device
and subdevice, when loading the module:
$ modprobe snd_aloop enable=1 timer_source=[<card>[.<dev>[.<subdev>]]]
<card> is the name (id) of the sound card or a card number.
<dev> and <subdev> are device and subdevice numbers (defaults are 0).
Empty string as a value of timer_source= parameter enables previous
functionality (using jiffies timer).
