7c1543f6b5 ALSA: dice: add stream format parameters for Mytek devices
--nextPart3916812.EicPReet6m
Content-Transfer-Encoding: 7Bit
Content-Type: text/plain; charset="us-ascii"

Mytek manufactures some equipment with DICE-based firewire ports. These
devices contain old versions of DICE firmware which lacks detailed
stream format reporting for all sampling clock modes.

Building upon the recent work by Takashi Sakamoto, hard-coded parameters
are added for the Stereo 192 DSD-DAC. When the device vendor and model
match the coded parameters are copied into the stream format cache.

9d4d207d13 ALSA: timer: Assure timer resolution access always locked
There are still many places calling the timer's hw.c_resolution
callback without lock, and this may lead to some races, as we faced in
the commit a820ccbe21 ("ALSA: pcm: Fix UAF at PCM release via PCM
timer access").

This patch changes snd_timer_resolution() to take the timer->lock for
avoiding the races.  A place calling this function already inside the
lock (from the notifier) is replaced with the
snd_timer_hw_resolution() accordingly, as well as wrapping with the
lock around another place calling snd_timer_hw_resolution(), too.

21244e3d6a ALSA: seq: Avoid open-code for getting timer resolution
Instead of open-coding for getting the timer resolution, use the
standard snd_timer_resolution() helper.

The original code falls back to the callback function when the
resolution is zero, but it must be always so when the callback
function is defined.  So this should be no functional change.

ASoC: Intel: bytcr_rt5640: Set card long_name based on quirks
Many X86 devices using a BYT SoC + RT5640 codec are cheap devices with
generic DMI strings, causing snd_soc_set_dmi_name() to fail to set a
long_name, making it impossible for userspace to have a correct UCM
profile which only uses inputs / outputs which are actually hooked up
on the device.

Our quirks already specify which input the internal mic is connected to
and if a single (mono) speaker is used or if the device has stereo
speakers.

This commit sets a long_name based on the quirks so that userspace can
have UCM profiles doing the right thing based on the long_name.

Note that if we ever encounter the need for a special UCM profile for
some device we can add a quirk to set a specific long_name for the
device,

ASoC: Intel: bytcr_rt5640: Add quirks for various devices
Even with our recently tweaked defaults, quite a few bytcr_rt5640 devices
still need quirks to be fully functional. This commits adds quirks where
necessary for the 16 bytcr_rt5640 devices I have access to.

The quirks are added for the following reasons:

1) Devices with only one speaker need the mono quirk to avoid driving an
unused and potentially short-circuited output. 8 of my sample of 16 devs
are mono, 4 of these would work with the defaults if it were not for their
mono speaker.

2) Devices using a different input for the internal mic then the default,
this is the case for 6 of my sample of 16 devices.

3) BYTCR devices without an ACPI channel map, which do not work with the
default of SSP0-AIF2, this is the case for 2 of my sample of 16 devices.

4) Devices which need non-default jack-detect settings, this is the case
for 6 of my sample of 16 devices.

This commit add quirks for the following devices:

ASoC: Intel: bytcr_rt5640: Unify BYTCR input defaults
Currently we've 2 places with BYTCR defaults: 1. The generic catch-all
DMI_SYS_VENDOR=="Insyde" DMI quirk which selects SSP0-AIF1 for generic
Insyde BYTCR tablets without the ACPI channel package; and 2. the
defaults in the if (is_bytcr) {} code block.

Currently these are not identical, both select IN3 as the internal mic
output, but the "Insyde" DMI quirk leaves out the DIFF_MIC quirk. The
DIFF_MIC quirk should be enabled by default, because enabling diff. input
helps a lot for devices with a differential mic, where as it is a nop on
devices with a normal mic.

This commit adds the DIFF_MIC quirk to the "Insyde" DMI quirk path, by
adding a new BYTCR_INPUT_DEFAULTS define and using that in both code paths
which set BYTCR defaults.

Having a single place where the BYTCR input defaults are defined also
allows defining jack-detect defaults in a single place in a follow-up
commit.

dc82e52492 ALSA: core: Assure control device to be registered at last
The commit 289ca025ee ("ALSA: Use priority list for managing device
list") changed the way to register/disconnect/free devices via a
single priority list.  This helped to make behavior consistent, but it
also changed a slight behavior change: namely, the control device is
registered earlier than others, while it was supposed to be the very
last one.

I've put SNDRV_DEV_CONTROL in the current position as the release of
ctl elements often conflict with the private ctl elements some PCM or
other components may create, which often leads to a double-free.
But, the order of register and disconnect should be indeed fixed as
expected in the early days: the control device gets registered at
last, and disconnected at first.

This patch changes the priority list order to move SNDRV_DEV_CONTROL
as the last guy to assure the register / disconnect order.  Meanwhile,
for keeping the messy resource release order, manually treat the
control and lowlevel devices as last freed one.

Additional note:
The lowlevel device is the device where a card driver creates at
probe.  And, we still keep the release order control -> lowlevel, as
there might  be link from a control element back to a lowlevel object.

1d38f5d828 ALSA: usb-audio: UAC3 Add support for connector insertion.
This adds support for the UAC3 insertion controls. The status
is reported as a boolean value in the same way it used to do
for UAC2. Hence, the presence of any connector in the response
will make the control saying the jack is connected.

The UAC2 support for this control has been moved to a dedicated
control for connectors as both UAC2 and UAC3 follow a specific
Control Request Parameter Block for this control. This parameter
block for UAC3 could not be read in the same simplistic
manner as in UAC2.

This implementation is not requesting additional information
from the HIGH CAPABILITY Connectors descriptor.

Tested with an UAC3 device with UAC2 as legacy configuration.
The connector status can be read with `amixer` and the interrupt
is also caught with `alsactl monitor`.

This patch adds extra functions for shutdown on the Sound Blaster Z and
Recon3Di. The Recon3Di only has one specific functions, which sets the
GPIO data pins to 0 to prevent a popping noise.

The Sound Blaster Z exit sequence was taken from Windows. Without this
exit function, the card will not reload properly unless the PC has been
shutdown to clear the onboard memory. There are commented out functions
currently in the sbz_exit_chip function that are added in a later patch.

Also, a reboot notify function has been added, to make sure these
functions are ran before a reboot. This helps when using the card
through VFIO in a virtual machine, to make sure the card reloads the DSP
properly.

3f12888dfa ALSA: control: fix a redundant-copy issue
In snd_ctl_elem_add_compat(), the fields of the struct 'data' need to be
copied from the corresponding fields of the struct 'data32' in userspace.
This is achieved by invoking copy_from_user() and get_user() functions. The
problem here is that the 'type' field is copied twice. One is by
copy_from_user() and one is by get_user(). Given that the 'type' field is
not used between the two copies, the second copy is *completely* redundant
and should be removed for better performance and cleanup. Also, these two
copies can cause inconsistent data: as the struct 'data32' resides in
userspace and a malicious userspace process can race to change the 'type'
field between the two copies to cause inconsistent data. Depending on how
the data is used in the future, such an inconsistency may cause potential
security risks.

For above reasons, we should take out the second copy.

ASoC: cirrus: i2s: IRQ-based stream watchdog
I2S controller on EP93xx seems to have undocumented HW issue. According to
"EP93xx User’s Guide", controller can handle underflow and either transmit
last sample or zeroes in such case until FIFO is filled again. In reality
undeflow conditions seem to confuse internal state machine from time to
time and the whole stream gets shifted by one byte (as captured by logic
analyser on the I2S outputs). One could only hear noise instead of original
stream and this continues until the FIFO is disabled and enabled again.

Work this around by watching underflow interrupt and resetting I2S TX
channel + fill FIFO with zero samples until DMA catches up again. This is

ASoC: rt5640: Move checking of device-properties to component probe callback
On some platforms the platform code may need to add device-properties,
rather then relying only on properties set by the firmware.

This commit moves the parsing of the device-properties from the i2c-driver
probe() function, which may be called at any time, to the component-driver
probe() function, which gets called after the platform code calls
snd_soc_register_card().

This allows the platform code to attach extra device-properties before
the device-properties are parsed.

ASoC: rt5640: Remove is_sys_clk_from_pll, it has ordering issues
is_sys_clk_from_pll() is used as a snd_soc_dapm_route.connected callback,
checking RT5640_GBL_CLK to determine if the sys-clk is PLL1 and thus the
PWR_PLL bit in reg PWR_ANLG2 must be set.

RT5640_GBL_CLK is changed by rt5640_set_dai_sysclk(), which gets called by
the pre_pmu / post_pmd functions of the "Platform Clock" dapm-supply.

This creates an ordering issue, during a dapm transition first all
connected() callbacks are called to build a list of supplies to enable
and then the complete list is walked to enable the supplies. Since the
connected() check happens before enabling any supplies,
is_sys_clk_from_pll() ends up deciding if the PWR_PLL bit should be set
based on the state the "Platform Clock" supply had *before* the transition.
This sometimes results in PWR_PLL being off, even though *after* the
transition PLL1 is configured as sys-clk.

This commit removes is_sys_clk_from_pll() instead simply setting / clearing
PWR_PLL in rt5640_set_dai_sysclk() based on the selected sys-clk, which
fixes this and as a bonus results in a nice cleanup.

ASoC: Intel: bytcr_rt565: fix missing assignment to ret_val
Currently, the check that ret_val is not -ENOENT is always true and
the quirk bit BYT_RY5651_MCLK_EN is never being cleared because ret_val
is always zero at this point from a previous assignment earlier on.
I believe that ret_val should actually be assigned to the return from
devm_clk_get() as this can return -ENOENT (from a deeper call to
clk_get_sys) and that was the original intention to check this.

07eca5fc3e ALSA: usb-audio: Allow to override the longname string
Historically USB-audio driver sets the card's longname field with the
details of the device and the bus information.  It's good per se, but
not preferable when it's referred as the identifier for UCM profile.

This patch adds a quirk profile_name field to override the card's
longname string to a pre-defined one, so that one can create a unique
and consistent ID string for the specific USB device via a quirk table
to be used as a UCM profile name.

The patch does a slight code refactoring to split out the functions to
set shortname and longname fields as well.

4120fbedbb ALSA: usb-audio: Add "Keep Interface" control
This patch adds "Keep Interface" control for each USB-audio device.
The control element is with SND_CTL_IFACE_CARD, so that it won't
appear on any sane mixer applications.  For a device that is confirmed
to work well with "keep-interface" mode, user can flip the control via
amixer, e.g.
  % amixer -c1 cset iface=CARD,name='Keep Interface' on

and save/restore the state via alsactl.

The reason to provide this via control API is that the behavior must
be pretty depending on the device (and the firmware in it), so it's
not ideal to apply via module option.

For a device that certainly works, we may set it statically via a
quirk table entry.  But a device like Dell WD15 dock behaves so
differently depending on the firmware, and we can't set it
statically.  So leave this as a dynamic switch each user can adjust
freely.

8a463225b1 ALSA: usb-audio: Add keep_iface flag
Introduce a new flag to struct snd_usb_audio for allowing the device
to skip usb_set_interface() calls at changing or closing the stream.
As of this patch, the flag is nowhere set, so it's just a place
holder.  The dynamic switching will be added in the following patch.

A background information for this change:

Dell WD15 dock with Realtek chip gives a very long pause at each time
the driver changes the altset, which eventually happens at every PCM
stream open/close and parameter change.  As the long pause happens in
each usb_set_interface() call, there is nothing we can do as long as
it's called.  The workaround is to reduce calling it as much as
possible, and this flag indicates that behavior.

In the early commit adcdd0d5a1 ("ALSA: usb-audio: Skip volume

for Dell dock to skip two mixer FU's for playback.  This supposed that
the device has always the proper initial volume, but it doesn't seem
always correct.

This patch adds the explicit initialization of the volumes to the
fixed 0dB at the device probe time.  Also, such a fixup is needed
after the resume, so a new function is hooked to the resume callback
as well.

9c367c01d3 ALSA: dice: remove local frag of force_two_pcms
At present, to add PCM substreams for each of available tx/rx streams,
this driver uses a condition based on model-name. This is not enough
to support unknown models.

In former commits, this driver gains cache of stream formats. For models
which support protocol extension, all of available steam formats are
cached. For known models, hard-coded stream formats are used to generate
the cache. For unknown models, stream formats at current mode of sampling
transmission frequency is cached.

Anyway, at least, the cached formats are used to expose constrains of PCM
substreams for userspace applications. Thus, The cached data can be also
used to add PCM substreams themselves, instead of the name-based
conditions.

This commit obsoletes local frag of force_two_pcms.

52759c0963 ALSA: dice: fix kernel NULL pointer dereference due to invalid calculation for array index
At a commit f91c9d7610 ('ALSA: firewire-lib: cache maximum length of
payload to reduce function calls'), maximum size of payload for tx
isochronous packet is cached to reduce the number of function calls.

This cache was programmed to updated at a first callback of ohci1394 IR
context. However, the maximum size is required to queueing packets before
starting the isochronous context.

As a result, the cached value is reused to queue packets in next time to
starting the isochronous context. Then the cache is updated in a first
callback of the isochronous context. This can cause kernel NULL pointer
dereference in a below call graph:

(sound/firewire/amdtp-stream.c)
amdtp_stream_start()
->queue_in_packet()
  ->queue_packet()
    (drivers/firewire/core-iso.c)
    ->fw_iso_context_queue()
      ->struct fw_card_driver.queue_iso()
      (drivers/firewire/ohci.c)
      = ohci_queue_iso()
        ->queue_iso_packet_per_buffer()
          buffer->pages[page]

The issued dereference occurs in a case that:
 - target unit supports different stream formats for sampling transmission
   frequency.
 - maximum length of payload for tx stream in a first trial is bigger
   than the length in a second trial.

In this case, correct number of pages are allocated for DMA and the 'pages'
array has enough elements, while index of the element is wrongly calculated
according to the old value of length of payload in a call of
'queue_in_packet()'. Then it causes the issue.

This commit fixes the critical bug. This affects all of drivers in ALSA
firewire stack in Linux kernel v4.12 or later.

8f22e52528 ALSA: seq: Fix races at MIDI encoding in snd_virmidi_output_trigger()
The sequencer virmidi code has an open race at its output trigger
callback: namely, virmidi keeps only one event packet for processing
while it doesn't protect for concurrent output trigger calls.

snd_virmidi_output_trigger() tries to process the previously
unfinished event before starting encoding the given MIDI stream, but
this is done without any lock.  Meanwhile, if another rawmidi stream
starts the output trigger, this proceeds further, and overwrites the
event package that is being processed in another thread.  This
eventually corrupts and may lead to the invalid memory access if the
event type is like SYSEX.

The fix is just to move the spinlock to cover both the pending event
and the new stream.

The bug was spotted by a new fuzzer, RaceFuzzer.

ASoC: compress: Only call free for components which have been opened
The core should only call free on a component if said component has
already had open called on it. This is not presently the case and most
compressed drivers in the kernel assume it will be. This causes null
pointer dereferences in the drivers as they attempt clean up for stuff
that was never put in place.

This is fixed by aborting calling open callbacks once a failure is
encountered and then during clean up only iterating through the
component list to that point.

This is a fairly quick fix to the issue, to allow backporting. There
is more refactoring to follow to tidy the code up a little.

8a7d6003df ALSA: hda - Skip jack and others for non-existing PCM streams
When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited
number of devices available, and HD-audio, especially with HDMI/DP
codec, will fail to create more than two devices.

The driver warns about the lack of such devices and skips the PCM
device creations, but the HDMI driver still tries to create the
corresponding JACK, SPDIF and ELD controls even for the non-existing
PCM substreams.  This results in confusion on user-space, and even may
break the operation.

Similarly, Intel HDMI/DP codec builds the ELD notification from i915
graphics driver, and this may be broken if a notification is sent for
the non-existing PCM stream.

This patch adds the check of the existence of the assigned PCM
substream in the both scenarios above, and skips the further operation
if the PCM substream is not assigned.

f526afcd8f ALSA: rme9652: Hardening for potential Spectre v1
As recently Smatch suggested, one place in RME9652 driver may expand
the array directly from the user-space value with speculation:
  sound/pci/rme9652/rme9652.c:2074 snd_rme9652_channel_info() warn: potential spectre issue 'rme9652->channel_map' (local cap)

This patch puts array_index_nospec() for hardening against it.
