We recently made "format" a u64 variable so now static checkers complain
that this shift will wrap around if format is more than 31. I don't
think it makes a difference for runtime, but it's simple to silence the

The previous fix 40cab6e88cb0 ("ALSA: pcm: Return -EBUSY for OSS
ioctls changing busy streams") introduced some mutex unbalance; the
check of runtime->oss.rw_ref was inserted in a wrong place after the
mutex lock.
This patch fixes the inconsistency by rewriting with the helper
functions to lock/unlock parameters with the stream check.

When trying to use the driver (e.g. aplay *.wav), the 4MiB DMA buffer
will get mmapp'ed in 16KiB chunks. But this fails with the 2nd 16KiB
area, as the page offset is outside of the VMA range (size), which is
currently used as size parameter in snd_pcm_lib_default_mmap(). By
using the DMA buffer size (dma_bytes) instead, the complete DMA buffer
can be mmapp'ed and the issue is fixed.
This issue was detected on an ARM platform (TI AM57xx) using the RME
HDSP MADI PCIe soundcard.

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.
Tested with a UAC2 audio device with connector control capability.

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.

Although we apply the params_lock mutex to the whole read and write
operations as well as snd_pcm_oss_change_params(), we may still face
some races.
First off, the params_lock is taken inside the read and write loop.
This is intentional for avoiding the too long locking, but it allows
the in-between parameter change, which might lead to invalid
pointers. We check the readiness of the stream and set up via
snd_pcm_oss_make_ready() at the beginning of read and write, but it's
called only once, by assuming that it remains ready in the rest.
Second, many ioctls that may change the actual parameters
(i.e. setting runtime->oss.params=1) aren't protected, hence they can
be processed in a half-baked state.
This patch is an attempt to plug these holes. The stream readiness
check is moved inside the read/write inner loop, so that the stream is
always set up in a proper state before further processing. Also, each
ioctl that may change the parameter is wrapped with the params_lock
for avoiding the races.
The issues were triggered by syzkaller in a few different scenarios,
particularly the one below appearing as GPF in loopback_pos_update.

Integrate the native DSD support quirk codes of "ITF-USB DSD" based DACs.
Now, "is_itf_usb_dsd_2alts_dac()" and "is_itf_usb_dsd_3alts_dac()" is
integrated into one function "is_itf_usb_dsd_dac()".
So, remove the logic to distinguish UD-501 and UD-501V2 by the
"Product Name".
The integration is possible by changing the following two functions.
- snd_usb_select_mode_quirk():
Change the determination condition of the DSD mode switch command,
from the altset number being used, to the audio format being played.
Actually, this operation is same as playback using ASIO driver in
Windows environment.
- snd_usb_interface_dsd_format_quirk():
To which altset supports native DSD is determined by the number of altsets.
Previously, it's a constant "2" or "3".

In loopback_open() and loopback_close(), we assign and release the
substream object to the corresponding cable in a racy way. It's
neither locked nor done in the right position. The open callback
assigns the substream before its preparation finishes, hence the other
side of the cable may pick it up, which may lead to the invalid memory
access.
This patch addresses these: move the assignment to the end of the open
callback, and wrap with cable->lock for avoiding concurrent accesses.

The aloop driver tries to stop the pending timer via timer_del() in
the trigger callback and in the close callback. The former is
correct, as it's an atomic operation, while the latter expects that
the timer gets really removed and proceeds the resource releases after
that. But timer_del() doesn't synchronize, hence the running timer
may still access the released resources.
A similar situation can be also seen in the prepare callback after
trigger(STOP) where the prepare tries to re-initialize the things
while a timer is still running.
The problems like the above are seen indirectly in some syzkaller
reports (although it's not 100% clear whether this is the only cause,
as the race condition is quite narrow and not always easy to
trigger).
For addressing these issues, this patch adds the explicit alls of
timer_del_sync() in some places, so that the pending timer is properly
killed / synced.

Recently released USB Audio Class 3.0 specification
introduces many significant changes comparing to
previous versions, like
- new Power Domains, support for LPM/L1
- new Cluster descriptor
- changed layout of all class-specific descriptors
- new High Capability descriptors
- New class-specific String descriptors
- new and removed units
- additional sources for interrupts
- removed Type II Audio Data Formats
- ... and many other things (check spec)
It also provides backward compatibility through
multiple configurations, as well as requires
mandatory support for BADD (Basic Audio Device
Definition) on each ADC3.0 compliant device
This patch adds initial support of UAC3 specification
that is enough for Generic I/O Profile (BAOF, BAIF)
device support from BADD document.

We've observed too long probe time with Coffee Lake (CFL) machines,
and the likely cause is some communication problem between the
HD-audio controller and the codec chips. While the controller expects
an IRQ wakeup for each codec response, it seems sometimes missing, and
it takes one second for the controller driver to time out and read the
response in the polling mode.
Although we aren't sure about the real culprit yet, in this patch, we
put a workaround by forcing the polling mode as default for CFL
machines; the polling mode itself isn't too heavy, and much better
than other workarounds initially suggested (e.g. disabling
power-save), at least.

Some HP laptops have a mute mute LED controlled by a pin VREF. The
Realtek codec driver updates the VREF via vmaster hook by calling
snd_hda_set_pin_ctl_cache().
This works fine as long as the driver is running in a normal mode.
However, when the VREF change happens during the codec being in
runtime PM suspend, the regmap access will skip and postpone the
actual register change. This ends up with the unchanged LED status
until the next runtime PM resume even if you change the Master mute
switch. (Interestingly, the machine keeps the LED status even after
the codec goes into D3 -- but it's another story.)
For improving this usability, let the driver temporarily powering up /
down only during the pin VREF change. This can be achieved easily by
wrapping the call with snd_hda_power_up_pm() / *_down_pm().

With the commit 1ba8f9d30817 ("ALSA: hda: Add a power_save
blacklist"), we changed the default value of power_save option to -1
for processing the power-save blacklist.
Unfortunately, this seems breaking user-space applications that
actually read the power_save parameter value via sysfs and judge /
adjust the power-saving status. They see the value -1 as if the
power-save is turned off, although the actual value is taken from
CONFIG_SND_HDA_POWER_SAVE_DEFAULT and it can be a positive.
So, overall, passing -1 there was no good idea. Let's partially
revert it -- at least for power_save option default value is restored
again to CONFIG_SND_HDA_POWER_SAVE_DEFAULT. Meanwhile, in this patch,
we keep the blacklist behavior and make is adjustable via the new
option, pm_blacklist.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
- Fix an uninitialized variable false warning in dm bufio
- Fix DM's passthrough ioctl support to be race free against an
underlying device being removed.
- Fix corner-case of DM raid resync reporting if/when the raid becomes
degraded during resync; otherwise automated raid repair will fail.
- A few DM multipath fixes to make non-SCSI optimizations, that were
introduced during the 4.16 merge, useful for all non-SCSI devices,
rather than narrowly define this non-SCSI mode in terms of "nvme".
This allows the removal of "queue_mode nvme" that really didn't need
to be introduced. Instead DM core will internalize whether
nvme-specific IO submission optimizations are doable and DM multipath
will only do SCSI-specific device handler operations if SCSI is in
use.
* tag 'for-4.16/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm table: allow upgrade from bio-based to specialized bio-based variant
dm mpath: remove unnecessary NVMe branching in favor of scsi_dh checks
dm table: fix "nvme" test
dm raid: fix incorrect sync_ratio when degraded
dm: use blkdev_get rather than bdgrab when issuing pass-through ioctl
dm bufio: avoid false-positive Wmaybe-uninitialized warning

Pull rdma fixes from Doug Ledford:
- Various driver bug fixes in mlx5, mlx4, bnxt_re and qedr, ranging
from bugs under load to bad error case handling
- There in one largish patch fixing the locking in bnxt_re to avoid a
machine hard lock situation
- A few core bugs on error paths
- A patch to reduce stack usage in the new CQ API
- One mlx5 regression introduced in this merge window
- There were new syzkaller scripts written for the RDMA subsystem and
we are fixing issues found by the bot
- One of the commits (aa0de36a40f4 “RDMA/mlx5: Fix integer overflow
while resizing CQ”) is missing part of the commit log message and one
of the SOB lines. The original patch was from Leon Romanovsky, and a
cut-n-paste separator in the commit message confused patchworks which
then put the end of message separator in the wrong place in the
downloaded patch, and I didn’t notice in time. The patch made it into
the official branch, and the only way to fix it in-place was to
rebase. Given the pain that a rebase causes, and the fact that the
patch has relevant tags for stable and syzkaller, a revert of the
munged patch and a reapplication of the original patch with the log
message intact was done.
