Robert Jarzmik 6bd25aae3a ASoC: wm97xx: fix compilation corner case
When the old AC97 is not used, CONFIG_SND_SOC_AC97_BUS is not
defined. As a consequence, in the error path, snd_soc_free_ac97_codec()
is not defined and triggers a compilation error.

Fix it for wm9705 and wm9712, as wm9713 is correctly written.

Takashi Iwai 6ca73de7eb ALSA: pcm: Forcibly stop at disconnect callback
So far we assumed that each driver implements the hotplug PCM handling
properly, e.g. dealing with the pending PCM stream at disconnect
callback.  But most codes don't care, and it eventually leaves the PCM
stream inconsistent state when an abrupt disconnection like sysfs
unbind happens.

This patch is simple but a big-hammer solution: invoke snd_pcm_stop()
at the common PCM disconnect callback always when the stream is
running.

Takashi Iwai 8b645e4a40 ALSA: pcm: Don't call register and disconnect callbacks for internal PCM
The internal PCM (aka DPCM backend PCM) doesn't need any registration
procedure, thus currently we bail out immediately at dev_register
callback.  Similarly, its counterpart, dev_disconnect callback, is
superfluous for the internal PCM.  For simplifying and avoiding the
conflicting disconnect call for internal PCM objects, this patch drops
dev_register and dev_disconnect callbacks for the internal ops.

The only uncertain thing by this action is whether skipping the PCM
state change to SNDRV_PCM_STATE_DISCONNECT for the internal PCM is
mandatory.  Looking through the current implementations, this doesn't
look so, hence dropping the whole dev_disconnect would make more
sense.

Ben Hutchings 8009d506a1 ALSA: seq: Enable 'use' locking in all configurations
The 'use' locking macros are no-ops if neither SMP or SND_DEBUG is
enabled.  This might once have been OK in non-preemptible
configurations, but even in that case snd_seq_read() may sleep while
relying on a 'use' lock.  So always use the proper implementations.

Takashi Iwai c44027c89e ALSA: add snd_card_disconnect_sync()
In case of user unbind ALSA driver during playing back / capturing,
each driver needs to stop and remove it correctly. One note here is
that we can't cancel from remove function in such case, because
unbind operation doesn't check return value from remove function.
So, we *must* stop and remove in this case.

For this purpose, we need to sync (= wait) until the all top-level
operations are canceled at remove function.
For example, snd_card_free() processes the disconnection procedure at
first, then waits for the completion. That's how the hot-unplug works
safely. It's implemented, at least, in the top-level driver removal.

Now for the lower level driver, we need a similar strategy. Notify to
the toplevel for hot-unplug (disconnect in ALSA), and sync with the
stop operation, then continue the rest of its own remove procedure.

This patch adds snd_card_disconnect_sync(), and driver can use it from
remove function.

Note: the "lower level" driver here refers to a middle layer driver
(e.g. ASoC components) that can be unbound freely during operation.
Most of legacy ALSA helper drivers don't have such a problem because
they can't be unbound.

Note#2: snd_card_disconnect_sync() merely calls snd_card_disconnect()
and syncs with closing all pending files.  It takes only the files
opened by user-space into account, and doesn't care about object
refcounts.  (The latter is handled by snd_card_free() completion call,
BTW.)  Also, the function doesn't free resources by itself.

Takashi Iwai 7110599884 ALSA: seq: Fix use-after-free at creating a port
There is a potential race window opened at creating and deleting a
port via ioctl, as spotted by fuzzing.  snd_seq_create_port() creates
a port object and returns its pointer, but it doesn't take the
refcount, thus it can be deleted immediately by another thread.
Meanwhile, snd_seq_ioctl_create_port() still calls the function
snd_seq_system_client_ev_port_start() with the created port object
that is being deleted, and this triggers use-after-free like:

We may fix this in a few different ways, and in this patch, it's fixed
simply by taking the refcount properly at snd_seq_create_port() and
letting the caller unref the object after use.  Also, there is another
potential use-after-free by sprintf() call in snd_seq_create_port(),
and this is moved inside the lock.

This fix covers CVE-2017-15265.

Actually such a URB is killed properly at disconnection when the
device gets probed successfully, and what we need is to apply it for
the error-path, too.

In this patch, we apply snd_usb_mixer_disconnect() at releasing.
Also introduce a new flag, disconnected, to struct usb_mixer_interface
for not performing the disconnection procedure twice.

Takashi Iwai 19b592dae8 ALSA: seq: Add sanity check for user-space pointer delivery
The sequencer event may contain a user-space pointer with its
SNDRV_SEQ_EXT_USRPTR bit, and we assure that its delivery is limited
with non-atomic mode.  Otherwise the copy_from_user() may hit the
fault and cause a problem.  Although the core code doesn't set such a
flag (only set at snd_seq_write()), any wild driver may set it
mistakenly and lead to an unexpected crash.

This patch adds a sanity check of such events at the delivery core
code to filter out the invalid invocation in the atomic mode.

Arnd Bergmann 667ebc97c9 ASoC: dapm: add initialization for w_param_text pointer
We now allocate the array conditionally, but we always pass
the pointer to the new snd_soc_dapm_free_kcontrol() function,
which introduces a warning for the case that it is not
initialized:

sound/soc/soc-dapm.c: In function 'snd_soc_dapm_new_pcm':
sound/soc/soc-dapm.c:3940:2: error: 'w_param_text' may be used uninitialized in this function [-Werror=maybe-uninitialized]

As snd_soc_dapm_free_kcontrol() is global, it doesn't get inlined
and gcc fails to notice that we don't actually access the array
in that case, so the code is actually safe. Adding an initialization
for the array pointer shuts up the warning.

While line6_probe() may kick off URB for a control MIDI endpoint, the

in a leftover URB action that is eventually triggered later and causes
an Oops like:

Since the whole clean-up procedure is done in line6_disconnect()

open-coding the whole again.  It'll fix such an issue automagically.

Takashi Iwai 5803b02388 ALSA: seq: Fix copy_from_user() call inside lock
The event handler in the virmidi sequencer code takes a read-lock for
the linked list traverse, while it's calling snd_seq_dump_var_event()
in the loop.  The latter function may expand the user-space data
depending on the event type.  It eventually invokes copy_from_user(),
which might be a potential dead-lock.

The sequencer core guarantees that the user-space data is passed only
with atomic=0 argument, but snd_virmidi_dev_receive_event() ignores it
and always takes read-lock().  For avoiding the problem above, this
patch introduces rwsem for non-atomic case, while keeping rwlock for
atomic case.

Also while we're at it: the superfluous irq flags is dropped in
snd_virmidi_input_open().

anish kumar 19ad683abc ASoC: dapm: Avoid creating kcontrol for params
Currently in codec to codec dai link if there are multiple
params defined then dapm can use created kcontrol to
decide which param to apply at runtime.

However, in case there is only single param configuration
then there is no point in creating the kcontrol and also there
is no point in allocating memory for kcontrol.

In the snd_soc_dapm_new_pcm function, there is memory
allocation happening for kcontrol which is later used
or not used based on num_param. It is better to not
allocate memory when there is only a single configuration.
This change is to remedy that anomaly.

Kuninori Morimoto 7dd5d0d954 ASoC: soc-core: add component lookup functions
ALSA SoC platform/codec will be replaced to component soon.
This means 1 device might have multiple components. But current
unregister component function only checks "dev" to find it.
This means, unexpected component might be unregistered by current
function.
But, it is no problem if driver registered only 1 component.

To prepare avoid this issue, this patch adds new component
lookup function. it finds component by "dev" and "driver name".

Here, the reason why it uses "driver name" is that "component name"
was created by fmt_single_name() and difficult to use it from driver.
Driver of course knows its "driver name", thus, using it is more easy.

Takashi Iwai 7682e39948 ALSA: usx2y: Suppress kernel warning at page allocation failures
The usx2y driver allocates the stream read/write buffers in continuous
pages depending on the stream setup, and this may spew the kernel
warning messages with a stack trace like:
  WARNING: CPU: 1 PID: 1846 at mm/page_alloc.c:3883
  __alloc_pages_slowpath+0x1ef2/0x2d70
  Modules linked in:
  CPU: 1 PID: 1846 Comm: kworker/1:2 Not tainted
  ....

It may confuse user as if it were any serious error, although this is
no fatal error and the driver handles the error case gracefully.
Since the driver has already some sanity check of the given size (128
and 256 pages), it can't pass any crazy value.  So it's merely page
fragmentation.

This patch adds __GFP_NOWARN to each caller for suppressing such
kernel warnings.  The original issue was spotted by syzkaller.

Takashi Sakamoto 51db452df0 Revert "ALSA: echoaudio: purge contradictions between dimension matrix members and total number of members"
This reverts commit 275353bb68 to fix a regression which can abort
'alsactl' program in alsa-utils due to assertion in alsa-lib.

alsactl: control.c:2513: snd_ctl_elem_value_get_integer: Assertion `idx < sizeof(obj->value.integer.value) / sizeof(obj->value.integer.value[0])' failed.

alsactl: control.c:2976: snd_ctl_elem_value_get_integer: Assertion `idx < ARRAY_SIZE(obj->value.integer.value)' failed.

This commit is a band-aid. In a point of usage of ALSA control interface,
the drivers still bring an issue that they prevent userspace applications
to have a consistent way to parse each levels of the dimension information
via ALSA control interface.

Let me investigate this issue. Current implementation of the drivers
have three control element sets with dimension information:
 * 'Monitor Mixer Volume' (type: integer)
 * 'VMixer Volume' (type: integer)
 * 'VU-meters' (type: boolean)

Although the number of elements named as 'Monitor Mixer Volume' differs
depending on drivers in this group, it can be calculated by macros
defined by each driver (= (BX_NUM - BX_ANALOG_IN) * BX_ANALOG_IN). Each
of the elements has one member for value and has dimension information
with 2 levels (= BX_ANALOG_IN * (BX_NUM - BX_ANALOG_IN)). For these
elements, userspace applications are expected to handle the dimension
information so that all of the elements construct a matrix where the
number of rows and columns are represented by the dimension information.

The same way is applied to elements named as 'VMixer Volume'. The number
of these elements can also be calculated by macros defined by each
drivers (= PX_ANALOG_IN * BX_ANALOG_IN). Each of the element has one
member for value and has dimension information with 2 levels
(= BX_ANALOG_IN * PX_ANALOG_IN). All of the elements construct a matrix
with the dimension information.

An element named as 'VU-meters' gets a different way in a point of
dimension information. The element includes 96 members for value. The
element has dimension information with 3 levels (= 3 or 2 * 16 * 2). For
this element, userspace applications are expected to handle the dimension
information so that all of the members for value construct a matrix
where the number of rows and columns are represented by the dimension
information. This is different from the way for the former.

As a summary, the drivers were not designed to produce a consistent way to
parse the dimension information. This makes it hard for general userspace
applications such as amixer to parse the information by a consistent way,
and actually no userspace applications except for 'echomixer' utilize the
dimension information. Additionally, no drivers excluding this group use
the information.

The reverted commit was written based on the latter way. A commit
860c1994a7 ('ALSA: control: add dimension validator for userspace
elements') is written based on the latter way, too. The patch should be
reconsider too in the same time to re-define a consistent way to parse the
dimension information.

Damien Riegel d430a7e3ab ASoC: codecs: msm8916-wcd-analog: use btn0 released detection
msm8916-wcd-analog uses button0 to differentiate between headphone and
headset. Under some circumstances, button pressed and released
interrupts are not fired as the driver expects it.

For instance, with some connectors, there are spurious button-pressed
interrupts when unplugging a headphone, without the corresponding
button-released interrupt. But the codec always alternates between
button pressed and released interrupts, it cannot fire two interrupts of
the same kind in a row. That means that when the headphone is plugged
back, only a button-released interrupt will be fired instead of pressed
then released. This causes the driver to report headphone as headset.

By changing the logic and relying on button 0 release interrupt, the
driver could be made more robust for connectors that differ from the one
used on the Dragonboard's audio mezzanine.

In current ALSA SoC, Codec only has set_bias_level feature.
Codec will be merged into Component in next generation ALSA SoC,
thus current Codec specific feature need to be merged into it.
This is glue patch for it.

Codec driver has .idle_bias_off for dapm bias. But Component
driver doesn't have it, and dapm->idle_bias_off is set as "true".
To keep compatibility, this patch adds "idle_bias_on" instead of
".idle_bias_off" on Component driver.
dapm->idle_bias_off will be set by inverted idle_bias_on.

When we replace Codec to Component, the driver which has
".idle_bias_off = true" is just remove it,
and the driver which doesn't have it will have new
".idle_bias_on = true".

Takashi Iwai 5d61f0ba65 ASoC: pcm: Sync delayed work before releasing resources
When ASoC driver is unbound dynamically during its operation (i.e. a
kind of hot-unplug), we may hit Oops due to the resource access after
the release by a delayed work, something like:

  Unable to handle kernel paging request at virtual address dead000000000220
  ....

Charles Keepax d24e95f875 ASoC: wm8998: Correct handling of input muxes
Currently, wm8998 has two input mux controls on IN1 and attempts to
switch these together when the A position is configured to be in digital
mode. This is because the digital mode requires pins from both the L and
R channels. However, this doesn't work as intended because whilst the
registers on the chip are changed the corresponding DAPM
representation is only updated for the mux actually being changed by the
user. The DAPM graph being out of sync with the hardware can cause some
odd issues with incorrect things being powered etc.

To avoid this issue and simplify the code somewhat, simply let the user
set the muxes as they desire. If they set an invalid configuration they
might not get audio from the DMIC but most of the chip requires you to
set a valid audio route to get audio.

Kuninori Morimoto 81cb71240e ASoC: rsnd: add rsnd_dma_alloc()
R-Car sound DMA will be used from SSI/SRC.
dma.c doesn't alloc DMA handler in .probe timing, because we don't
know what kind of DMA transfer will be used then.
Thus, SSI/SRC have *rsnd_mod for DMA. rsnd_dma_attach() will allocate
it and attach it to system.
It will be PIO mode if it can't alloc DMA handler.

In case of MIX is used, rsnd_dma_attach() will be called twice from SSI.
To avoid duplicate allocation, current rsnd_dma_attach() is checking
allocated DMA handler. This DMA related operation is a little bit
difficult to understand.
This patch adds new rsnd_dma_alloc() and separates allocation and attach
for readable code.

jiada wang 957ce0c6b8 ASoC: soc-pcm: check symmetry after hw_params
hw_params may be fixup by be_hw_params_fixup, calling
soc_pcm_params_symmetry() before hw_params will have issue
if there is hw_params changes in be_hw_params_fixup.

For example, with following use case
1. a dai-link which is able to convert sample rate on BE side
2. set BE playback and capture sample rate to 44100Hz
3. play a 48000Hz audio stream with this dai-link
4. record from this dai-link with 44100Hz sample rate

Got following error message when record starts
[  495.013527]  be_link_ak4613: ASoC: unmatched rate symmetry: 48000 - 44100
[  495.021729]  be_link_ak4613: ASoC: hw_params BE failed -22
[  495.028589]  rsnd_link0: ASoC: hw_params BE failed -22

Because in soc_pcm_hw_params(), FE rate is still having value before
it is fixup by be_hw_params_fixup(), when soc_pcm_params_symmetry() checks
symmetry, thus soc_pcm_params_symmetry() complains about the unmatched rate
between the active stream and the new stream tries to start.

This patch moves soc_pcm_params_symmetry() after hw_params to resolve the
above issue.

Sriram Periyasamy 5a5d718f95 ALSA: hda - program ICT bits to support HBR audio
On recent Intel platforms (Haswell, Broadwell, Skylake, ApolloLake,
KabyLake, ...), the IEC Coding Type (ICT) bitfield in the Digital
Converter Control #3 needs to be set explicitly for HDMI/DisplayPort
High Bit Rate (HBR) audio playback to work. This was not required in
earlier platforms when HBR was first introduced. The ICT bits are
defined in Section 7.3.3.9 of the HDaudio 1.0a specification.

Since the ICT bitfield was not specified for HDAudio 1.0 devices
(before 2009), we only program it on machines more recent than
Haswell.

We tested that this fix is not needed on Baytrail-I (MinnowBoard
Turbot) and believe by extension it also does not apply to Braswell.

Meng Xu e1af344df4 ALSA: asihpi: fix a potential double-fetch bug when copying puhm
The hm->h.size is intended to hold the actual size of the hm struct
that is copied from userspace and should always be <= sizeof(*hm).

However, after copy_from_user(hm, puhm, hm->h.size), since userspace
process has full control over the memory region pointed by puhm, it is
possible that the value of hm->h.size is different from what is fetched-in
previously (get_user(hm->h.size, (u16 __user *)puhm)). In other words,
hm->h.size is overriden and the relation between hm->h.size and the hm
struct is broken.

This patch proposes to use a seperate variable, msg_size, to hold
the value of the first fetch and override hm->h.size to msg_size
after the second fetch to maintain the relation.

Add specific cpu_dai_name to dai_link because samsung i2s driver registers
two dais and components. Selecting one of them clearly is needed more

to use 'samsung-i2s' for cpu_dai is that 'samsung-i2s-sec' doesn't have a

name will follow their parent dev name, if the name isn't described.  In
case of this driver, each dais will have same name like '11440000.i2s0' by

The problem having same name is that TM2 machine driver can't detect
capture devices correctly. Machine driver doesn't know which one is proper
to use for cpu dai. The driver just selects to use 'samsung-i2c-sec' that
doesn't have capture functionality because the component of
samsung-i2s-sec is located in the first of the component_list.

I add dai name like 'samsung-i2s', 'samsung-i2s-sec' for each dais. The
reason why adding dai id to 1 is that it doesn't allow to use particular
dai name in case of when I use 0 for dai id.

The legacy byt-max98090 machine driver is still maintained but can

Nicolin Chen b0a7043d5c ASoC: fsl_ssi: Caculate bit clock rate using slot number and width
The set_sysclk() now is used to override the output bit clock rate.
But this is not a common way to implement a set_dai_sysclk(). And
this creates a problem when a general machine driver (simple-card
for example) tries to do set_dai_sysclk() by passing an input clock
rate for the baud clock instead of setting the bit clock rate as
fsl_ssi driver expected.

So this patch solves this problem by firstly removing set_sysclk()
since the hw_params() can calculate the bit clock rate. Secondly,
in order not to break those TDM use cases which previously might
have been using set_sysclk() to override the bit clock rate, this
patch changes the driver to calculate the bit clock rate using the
slot number and the slot width from the via set_tdm_slot().

The patch also removes an obsolete comment of the dir parameter.

Guneshwor Singh a931b9ce93 ALSA: compress: Remove unused variable
Commit 04c5d5a430 ("ALSA: compress: Embed struct device") removed
the statement that used 'str' but didn't remove the variable itself.
So remove it.

Dan Carpenter c4fd43793b ALSA: hwdep: prevent a harmless shift wrapping bug
The "info.index" variable represents a bit in hw->dsp_loaded which is
an unsigned int.  If it's higher than 31 we hit a shift wrapping bug.
This seems harmless, but I wanted to silence the static checker warning.

If this sanity check fails, we must free the memory that has already been

if 'se = kzalloc()' fails in the 'for' loop, we will branch to 'err'.
But in this case, 'kc[i].private_value' will still be NULL. A NULL pointer
dereference will then occur is the error handling path.

In such a case, it is safe to just 'continue' in order to skip this entry
and free the other ones.

Linus Torvalds d969443064 sound updates for 4.14-rc1
We have touched quite a lot of files but with fewer changes at this
 cycle; as you can see, most of changes are trivial fixes, especially
 constification patches.  Among the massive attacks by constification
 gangs, we had a few core changes (mostly for ASoC core), as well the
 fixes and the updates by major vendors.  Some highlights are below:
 
 ALSA core:
 - Fix possible races in control API user-TLV codes
 - Small cleanup of PCM core
 
 ASoC:
 - Continued work for componentization; still half-baked, but we're
   certainly progressing
 - Use of devres for jack detection GPIOs, rather as a cleanup
 - Jack detection support for Qualcomm MSM8916
 - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake

Ricard Wanderlof 1e6f4fc06f ASoC: adau17x1: Workaround for noise bug in ADC
The ADC in the ADAU1361 (and possibly other Analog Devices codecs)
exhibits a cyclic variation in the noise floor (in our test setup between
-87 and -93 dB), a new value being attained within this range whenever a
new capture stream is started. The cycle repeats after about 10 or 11
restarts.

The workaround recommended by the manufacturer is to toggle the ADOSR bit
in the Converter Control 0 register each time a new capture stream is
started.

I have verified that the patch fixes this problem on the ADAU1361, and
according to the manufacturer toggling the bit in question in this manner
will at least have no detrimental effect on other chips served by this
driver.

Commit fb087eaaef ("ALSA: hda - hdmi eld control created based on pcm")
forget to filter out invalid pcm numbers, if there is only one invalid pcm
number, then this issue causes we create eld control for invalid pcm silently,
but when there are more than one invalid pcm numbers, then this issue bring
probe error looks like below dmesg:

Quentin Schulz 4ab6cf11e7 ASoC: atmel-classd: remove aclk clock
Since gclk (generated-clk) is now able to determine the rate of the
audio_pll, there is no need for classd to have a direct phandle to the
audio_pll while already having a phandle to gclk.

Thus, remove all mentions to aclk in classd driver and update macros and
variable names.
