ALSA: rawmidi: Fix missing input substream checks in compat ioctls
Some rawmidi compat ioctls lack of the input substream checks
(although they do check only for rfile->output). This many eventually
lead to an Oops as NULL substream is passed to the rawmidi core
functions.
Fix it by adding the proper checks before each function call.
The bug was spotted by syzkaller.

ALSA: pcm: Remove WARN_ON() at snd_pcm_hw_params() error
snd_pcm_hw_params() (more exactly snd_pcm_hw_params_choose()) contains
a check of the return error from snd_pcm_hw_param_first() and _last()
with snd_BUG_ON() -- i.e. it may trigger WARN_ON() depending on the
kconfig.
This was a valid check in the past, as these functions shouldn't
return any error if the parameters have been already refined via
snd_pcm_hw_refine() beforehand. However, the recent rewrite
introduced a kmalloc() in snd_pcm_hw_refine() for removing VLA, and
this brought a possibility to trigger an error. As a result, syzbot
caught lots of superfluous kernel WARN_ON() and paniced via fault
injection.
As the WARN_ON() is no longer valid with the introduction of
kmalloc(), let's drop snd_BUG_ON() check, in order to make the world
peaceful place again.

ALSA: pcm: Fix endless loop for XRUN recovery in OSS emulation
The commit
02a5d6925cd3 ("ALSA: pcm: Avoid potential races between OSS
ioctls and read/write") split the PCM preparation code to a locked
version, and it added a sanity check of runtime->oss.prepare flag
along with the change. This leaded to an endless loop when the stream
gets XRUN: namely, snd_pcm_oss_write3() and co call
snd_pcm_oss_prepare() without setting runtime->oss.prepare flag and
the loop continues until the PCM state reaches to another one.
As the function is supposed to execute the preparation
unconditionally, drop the invalid state check there.

ALSA: pcm: Fix UAF at PCM release via PCM timer access
The PCM runtime object is created and freed dynamically at PCM stream
open / close time. This is tracked via substream->runtime, and it's
cleared at snd_pcm_detach_substream().
The runtime object assignment is protected by PCM open_mutex, so for
all PCM operations, it's safely handled. However, each PCM substream
provides also an ALSA timer interface, and user-space can access to
this while closing a PCM substream. This may eventually lead to a
UAF, as snd_pcm_timer_resolution() tries to access the runtime while
clearing it in other side.
Fortunately, it's the only concurrent access from the PCM timer, and
it merely reads runtime->timer_resolution field. So, we can avoid the
race by reordering kfree() and wrapping the substream->runtime
clearance with the corresponding timer lock.

ASoC: Updates for v4.17
This is a *very* big release for ASoC. Not much change in the core but
there s the transition of all the individual drivers over to components
which is intended to support further core work. The goal is to make it
easier to do further core work by removing the need to special case all
the different driver classes in the core, many of the devices end up
being used in multiple roles in modern systems.
We also have quite a lot of new drivers added this month of all kinds,
quite a few for simple devices but also some more advanced ones with
more substantial code.
- The biggest thing is the huge series from Morimoto-san which
converted everything over to components. This is a huge change by
code volume but was fairly mechanical
- Many fixes for some of the Realtek based Baytrail systems covering
both the CODECs and the CPUs, contributed by Hans de Goode.
- Lots of cleanups for Samsung based Odroid systems from Sylwester
Nawrocki.
- The Freescale SSI driver also got a lot of cleanups from Nicolin
Chen.
- The Blackfin drivers have been removed as part of the removal of the
architecture.
- New drivers for AKM AK4458 and AK5558, several AMD based machines,
several Intel based machines, Maxim MAX9759, Motorola CPCAP,
Socionext Uniphier SoCs, and TI PCM1789 and TDA7419

With the merge window having been delayed for another week here's
another batch of updates that came in during that week. There's a few
important fixes in here, mainly a fix for I/O on a number of devices
caused by some of the component rework and a fix for a potential issue
if more than one component in a link provides compressed operations.

When trying to use the driver (e.g. aplay *.wav), the 4MiB DMA buffer

area, as the page offset is outside of the VMA range (size), which is

using the DMA buffer size (dma_bytes) instead, the complete DMA buffer

The issue is a lot deeper than a missing permission check. sb->s_user_ns
was is improperly set as well. So in addition to the filesystem being
mounted when it should not be mounted, so things are not allow that should
be.
We are practically to the release of 4.16 and there is no agreement between
Al Viro and myself on what the code should looks like to fix things properly.
So revert the code to what it was before so that we can take our time
and discuss this properly.

This implements UAC2 jack detection support, presenting
jack status as a boolean read-only mono mixer.
The presence of any channel in the UAC2_TE_CONNECTOR
control for a terminal will result in the mixer saying
the jack is connected.
Mixer naming follows the convention in sound/core/ctljack.c,
terminating the mixer with " Jack".
For additional clues as to which jack is being presented,
the name is prefixed with " - Input Jack" or " - Output Jack"
depending on if it's an input or output terminal.
This is required because terminal names are ambiguous
between inputs and outputs and often duplicated -
Bidirectional terminal types (0x400 -> 0x4FF)
"... may be used separately for input only or output only.
These types require two Terminal descriptors. Both have the same type."
(quote from "USB Device Class Definition for Terminal Types")
Since bidirectional terminal types are common for headphone adapters,
this distinguishes between two otherwise identically-named
jack controls.

ALSA: pcm: Return -EBUSY for OSS ioctls changing busy streams
OSS PCM stream management isn't modal but it allows ioctls issued at
any time for changing the parameters. In the previous hardening
patch ("ALSA: pcm: Avoid potential races between OSS ioctls and
read/write"), we covered these races and prevent the corruption by
protecting the concurrent accesses via params_lock mutex. However,
this means that some ioctls that try to change the stream parameter
(e.g. channels or format) would be blocked until the read/write
finishes, and it may take really long.
Basically changing the parameter while reading/writing is an invalid
operation, hence it's even more user-friendly from the API POV if it
returns -EBUSY in such a situation.
This patch adds such checks in the relevant ioctls with the addition
of read/write access refcount.
