commit a2ff19f7b70118ced291a28d5313469914de451b upstream.
When releasing a client, we need to clear the clienttab[] entry at
first, then call snd_seq_queue_client_leave(). Otherwise, the
in-flight cell in the queue might be picked up by the timer interrupt
via snd_seq_check_queue() before calling snd_seq_queue_client_leave(),
and it's delivered to another queue while the client is clearing
queues. This may eventually result in an uncleared cell remaining in
a queue, and the later snd_seq_pool_delete() may need to wait for a
long time until the event gets really processed.
By moving the clienttab[] clearance at the beginning of release, any
event delivery of a cell belonging to this client will fail at a later
point, since snd_seq_client_ptr() returns NULL. Thus the cell that
was picked up by the timer interrupt will be returned immediately
without further delivery, and the long stall of snd_seq_delete_pool()
can be avoided, too.

commit d0f833065221cbfcbadf19fd4102bcfa9330006a upstream.
Although we've covered the races between concurrent write() and
ioctl() in the previous patch series, there is still a possible UAF in
the following scenario:
A: user client closed B: timer irq
-> snd_seq_release() -> snd_seq_timer_interrupt()
-> snd_seq_free_client() -> snd_seq_check_queue()
-> cell = snd_seq_prioq_cell_peek()
-> snd_seq_prioq_leave()
.... removing all cells
-> snd_seq_pool_done()
.... vfree()
-> snd_seq_compare_tick_time(cell)
... Oops
So the problem is that a cell is peeked and accessed without any
protection until it's retrieved from the queue again via
snd_seq_prioq_cell_out().
This patch tries to address it, also cleans up the code by a slight
refactoring. snd_seq_prioq_cell_out() now receives an extra pointer
argument. When it's non-NULL, the function checks the event timestamp
with the given pointer. The caller needs to pass the right reference
either to snd_seq_tick or snd_seq_realtime depending on the event
timestamp type.
A good news is that the above change allows us to remove the
snd_seq_prioq_cell_peek(), too, thus the patch actually reduces the
code size.

commit 40088dc4e1ead7df31728c73f5b51d71da18831d upstream.
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.

commit 01c0b4265cc16bc1f43f475c5944c55c10d5768f upstream.
snd_pcm_oss_get_formats() has an obvious use-after-free around
snd_mask_test() calls, as spotted by syzbot. The passed format_mask
argument is a pointer to the hw_params object that is freed before the
loop. What a surprise that it has been present since the original
code of decades ago...

commit d7789f5bcdb298c4a302db471b1b20f74a20de95 upstream.
Normal 512-byte get/set of a TLV isn't supported but we were
registering the normal get/set anyway and relying on omitting
the SNDRV_CTL_ELEM_ACCESS_[READ|WRITE] flags to prevent them
being called.
Trouble is if this gets broken in the core ALSA code - as it has
been since at least 4.14 - the standard get/set can be called
unexpectedly and corrupt memory.
There's no point providing functions that won't be called and
it's a trivial change. The benefit is that if the ALSA core gets
broken again we get a big fat immediate NULL dereference instead
of a memory corruption timebomb.

commit 7bd80091567789f1c0cb70eb4737aac8bcd2b6b9 upstream.
This patch is an attempt for further hardening against races between
the concurrent write and ioctls. The previous fix d15d662e89fc
("ALSA: seq: Fix racy pool initializations") covered the race of the
pool initialization at writer and the pool resize ioctl by the
client->ioctl_mutex (CVE-2018-1000004). However, basically this mutex
should be applied more widely to the whole write operation for
avoiding the unexpected pool operations by another thread.
The only change outside snd_seq_write() is the additional mutex
argument to helper functions, so that we can unlock / relock the given
mutex temporarily during schedule() call for blocking write.

commit d85739367c6d56e475c281945c68fdb05ca74b4c upstream.
This is a fix for a (sort of) fallout in the recent commit
d15d662e89fc ("ALSA: seq: Fix racy pool initializations") for
CVE-2018-1000004.
As the pool resize deletes the existing cells, it may lead to a race
when another thread is writing concurrently, eventually resulting a
UAF.
A simple workaround is not to allow the pool resizing when the pool is
in use. It's an invalid behavior in anyway.

commit e312a869cd726c698a75caca0d9e5c22fd3f1534 upstream.
The dock line-out pin (NID 0x17 of ALC3254 codec) on Dell Precision
7520 may route to three different DACs, 0x02, 0x03 and 0x06. The
first two DACS have the volume amp controls while the last one
doesn't. And unfortunately, the auto-parser assigns this pin to DAC3,
resulting in the non-working volume control for the line out.
Fix it by disabling the routing to DAC3 on the corresponding pin.

commit ae104a21e52b1f9aab342cf6924405177b720069 upstream.
This platform was only one phone Jack.
Add dummy lineout verb to fix automute mode disable.
This just the workaround.
[ More background information:
since the platform has only a headphone jack without speaker, the
driver doesn't create the auto-mute control. Meanwhile we do update
the headset mode via the automute hook in the driver, thus with this
setup, the headset won't be updated any longer.
By adding a dummy line-out pin here, the auto-mute is added by the
driver, and the headset update is triggered properly.
Note that this is different from the other
ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, which has the real line-out pin,
while this quirk adds a dummy line-out pin. -- tiwai ]

commit 71db96ddfa72671bd43cacdcc99ca178d90ba267 upstream.
We've added a quirk to enable the recent Lenovo dock support, where it
overwrites the pin configs of NID 0x17 and 19, not only updating the
pin config cache. It works right after the boot, but the problem is
that the pin configs are occasionally cleared when the machine goes to
PM. Meanwhile the quirk writes the pin configs only at the pre-probe,
so this won't be applied any longer.
For addressing that issue, this patch moves the code to overwrite the
pin configs into HDA_FIXUP_ACT_INIT section so that it's always
applied at both probe and resume time.

commit 1ba8f9d308174e647b864c36209b4d7934d99888 upstream.
On some boards setting power_save to a non 0 value leads to clicking /
popping sounds when ever we enter/leave powersaving mode. Ideally we would
figure out how to avoid these sounds, but that is not always feasible.
This commit adds a blacklist for devices where powersaving is known to
cause problems and disables it on these devices.
Note I tried to put this blacklist in userspace first:
https://github.com/systemd/systemd/pull/8128
But the systemd maintainers rightfully pointed out that it would be
impossible to then later remove entries once we actually find a way to
make power-saving work on listed boards without issues. Having this list
in the kernel will allow removal of the blacklist entry in the same commit
which fixes the clicks / plops.
The blacklist only applies to the default power_save module-option value,
if a user explicitly sets the module-option then the blacklist is not
used.
[ added an ifdef CONFIG_PM for the build error -- tiwai]

commit 5a23699a39abc5328921a81b89383d088f6ba9cc upstream.
The patch "ALSA: control: code refactoring for ELEM_READ/ELEM_WRITE
operations" introduced a potential for kernel memory corruption due
to an incorrect if statement allowing non-readable controls to fall
through and call the get function. For TLV controls a driver can omit
SNDRV_CTL_ELEM_ACCESS_READ to ensure that only the TLV get function
can be called. Instead the normal get() can be invoked unexpectedly
and as the driver expects that this will only be called for controls
<= 512 bytes, potentially try to copy >512 bytes into the 512 byte
return array, so corrupting kernel memory.
The problem is an attempt to refactor the snd_ctl_elem_read function
to invert the logic so that it conditionally aborted if the control
is unreadable instead of conditionally executing. But the if statement
wasn't inverted correctly.
The correct inversion of
if (a && !b)
is
if (!a || b)

commit d15d662e89fc667b90cd294b0eb45694e33144da upstream.
ALSA sequencer core initializes the event pool on demand by invoking
snd_seq_pool_init() when the first write happens and the pool is
empty. Meanwhile user can reset the pool size manually via ioctl
concurrently, and this may lead to UAF or out-of-bound accesses since
the function tries to vmalloc / vfree the buffer.
A simple fix is to just wrap the snd_seq_pool_init() call with the
recently introduced client->ioctl_mutex; as the calls for
snd_seq_pool_init() from other side are always protected with this
mutex, we can avoid the race.

commit fdcc968a3b290407bcba9d4c90e2fba6d8d928f1 upstream.
These laptops have a combined jack to attach headsets, the U727 on
the left, the U757 on the right, but a headsets microphone doesn't
work. Using hdajacksensetest I found that pin 0x19 changed the
present state when plugging the headset, in addition to 0x21, but
didn't have the correct configuration (shown as "Not connected").
So this sets the configuration to the same values as the headphone
pin 0x21 except for the device type microphone, which makes it
work correctly. With the patch the configured pins for U727 are
Pin 0x12 (Internal Mic, Mobile-In): present = No
Pin 0x14 (Internal Speaker): present = No
Pin 0x19 (Black Mic, Left side): present = No
Pin 0x1d (Internal Aux): present = No
Pin 0x21 (Black Headphone, Left side): present = No

commit 447cae58cecd69392b74a4a42cd0ab9cabd816af upstream.
The layout of the UAC2 Control request and response varies depending on
the request type. With the current implementation, only the Layout 2
Parameter Block (with the 2-byte sized RANGE attribute) is handled
properly. For the Control requests with the 1-byte sized RANGE attribute
(Bass Control, Mid Control, Tremble Control), the response is parsed
incorrectly.
This commit:

commit 290df4d3ab192821b66857c05346b23056ee9545 upstream.
The soc_compr_copy callback is currently broken. Since the
changes to move the compr_ops over to the component the return
value is not correctly propagated, always returning zero on
success rather than the number of bytes copied. This causes
user-space to stall continuously reading as it does not believe
it has received any data.
Furthermore, the changes to move the compr_ops over to the
component iterate through the list of components and will call
the copy callback for any that have compressed ops. There isn't
currently any consensus on the mechanism to combine the results
of multiple copy callbacks.
To fix this issue for now halt searching the component list when
we locate a copy callback and return the result of that single
callback. Additional work should probably be done to look at the
other ops, tidy things up, and work out if we want to support
multiple components on a single compressed, but this is the only
fix required to get things working again.

commit 20a1ea2222e7cbf96e9bf8579362e971491e6aea upstream.
I got the following kernel warning when loading snd-soc-skl module on
Dell Latitude 7270 laptop:
memremap attempted on mixed range 0x0000000000000000 size: 0x0
WARNING: CPU: 0 PID: 484 at kernel/memremap.c:98 memremap+0x8a/0x180

It seems that the machine doesn't support the SKL DSP gives the empty
NHLT entry, and it triggers the warning. For avoiding it, let do the
zero check before calling memremap().

commit c66234cfedfc3e6e3b62563a5f2c1562be09a35d upstream.
When restoring registers during runtime resume, we must not write to
I2S_TXDR which is the transmit FIFO as this queues up a sample to be
output and pushes all of the output channels down by one.
This can be demonstrated with the speaker-test utility:
for i in a b c; do speaker-test -c 2 -s 1; done
which should play a test through the left speaker three times but if the
I2S hardware starts runtime suspended the first sample will be played
through the right speaker.
Fix this by marking I2S_TXDR as volatile (which also requires marking it
as readble, even though it technically isn't). This seems to be the
most robust fix, the alternative of giving I2S_TXDR a default value is
more fragile since it does not prevent regcache writing to the register
in all circumstances.
While here, also fix the configuration of I2S_RXDR and I2S_FIFOLR; these
are not writable so they do not suffer from the same problem as I2S_TXDR
but reading from I2S_RXDR does suffer from a similar problem.

The ACPI/machine-driver code refactoring introduced in 4.13 introduced

machine driver (the BIOS reports an invalid HID). The fix is just to
make sure the results of the quirk are actually used.

commit 1c9609e3a8cf5997bd35205cfda1ff2218ee793b upstream.
ALC256 has its own quirk to override the shutup call, and it contains
the COEF update for pulling down the headset jack control. Currently,
the COEF update is called after clearing the headphone pin, and this
seems triggering a stall of the codec communication, and results in a
long delay over a second at suspend.
A quick resolution is to swap the calls: at first with the COEF
update, then clear the headphone pin.

The ALSA sequencer ioctls have no protection against racy calls while
the concurrent operations may lead to interfere with each other. As
reported recently, for example, the concurrent calls of setting client
pool with a combination of write calls may lead to either the
unkillable dead-lock or UAF.
As a slightly big hammer solution, this patch introduces the mutex to
make each ioctl exclusive. Although this may reduce performance via
parallel ioctl calls, usually it's not demanded for sequencer usages,
hence it should be negligible.

muldiv32() contains a snd_BUG_ON() (which is morphed as WARN_ON() with
debug option) for checking the case of 0 / 0. This would be helpful
if this happens only as a logical error; however, since the hw refine
is performed with any data set provided by user, the inconsistent
values that can trigger such a condition might be passed easily.
Actually, syzbot caught this by passing some zero'ed old hw_params
ioctl.
So, having snd_BUG_ON() there is simply superfluous and rather
harmful to give unnecessary confusions. Let's get rid of it.

PCM OSS read/write loops keep taking the mutex lock for the whole
read/write, and this might take very long when the exceptionally high
amount of data is given. Also, since it invokes with mutex_lock(),
the concurrent read/write becomes unbreakable.
This patch tries to address these issues by replacing mutex_lock()
with mutex_lock_interruptible(), and also splits / re-takes the lock
at each read/write period chunk, so that it can switch the context
more finely if requested.

The loops for read and write in PCM OSS emulation have no proper check
of pending signals, and they keep processing even after user tries to
break. This results in a very long delay, often seen as RCU stall
when a huge unprocessed bytes remain queued. The bug could be easily
triggered by syzkaller.
As a simple workaround, this patch adds the proper check of pending
signals and aborts the loop appropriately.

The aloop driver tries to update the hw constraints of the connected
target on the cable of the opened PCM substream. This is done by
adding the extra hw constraints rules referring to the substream
runtime->hw fields, while the other substream may update the runtime
hw of another side on the fly.
This is, however, racy and may result in the inconsistent values when
both PCM streams perform the prepare concurrently. One of the reason
is that it overwrites the other's runtime->hw field; which is not only
racy but also broken when it's called before the open of another side
finishes. And, since the reference to runtime->hw isn't protected,
the concurrent write may give the partial value update and become
inconsistent.
This patch is an attempt to fix and clean up:
- The prepare doesn't change the runtime->hw of other side any longer,
but only update the cable->hw that is referred commonly.
- The extra rules refer to the loopback_pcm object instead of the
runtime->hw. The actual hw is deduced from cable->hw.
- The extra rules take the cable_lock to protect against the race.

The extra hw constraint rule for the formats the aloop driver
introduced has a slight flaw, where it doesn't return a positive value
when the mask got changed. It came from the fact that it's basically
a copy&paste from snd_hw_constraint_mask64(). The original code is
supposed to be a single-shot and it modifies the mask bits only once
and never after, while what we need for aloop is the dynamic hw rule
that limits the mask bits.
This difference results in the inconsistent state, as the hw_refine
doesn't apply the dependencies fully. The worse and surprisingly
result is that it causes a crash in OSS emulation when multiple
full-duplex reads/writes are performed concurrently (I leave why it
triggers Oops to readers as a homework).
For fixing this, replace a few open-codes with the standard
snd_mask_*() macros.

The aloop runtime object and its assignment in the cable are left even
when opening a substream fails. This doesn't mean any memory leak,
but it still keeps the invalid pointer that may be referred by the
another side of the cable spontaneously, which is a potential Oops
cause.
Clean up the cable assignment and the empty cable upon the error path
properly.

The commit 9027c4639ef1 ("ALSA: pcm: Call ack() whenever appl_ptr is
updated") introduced the possible error code returned from the PCM
rewind ioctl. Basically the change was for handling the indirect PCM
more correctly, but ironically, it caused rather a side-effect:
PulseAudio gets pissed off when receiving an error from rewind, throws
everything away and stops processing further, resulting in the
silence.
It's clearly a failure in the application side, so the best would be
to fix that bug in PA. OTOH, PA is mostly the only user of the rewind
feature, so it's not good to slap the sole customer.
This patch tries to mitigate the situation: instead of returning an
error, now the rewind ioctl returns zero when the driver can't rewind.
It indicates that no rewind was performed, so the behavior is
consistent, at least.
