[PATCH 5.16 02/37] llc: fix netdevice reference leaks in llc_ui_bind()

[Greg Kroah-Hartman]

From: Eric Dumazet <edumazet@google.com>

commit 764f4eb6846f5475f1244767d24d25dd86528a4a upstream.

Whenever llc_ui_bind() and/or llc_ui_autobind()
took a reference on a netdevice but subsequently fail,
they must properly release their reference
or risk the infamous message from unregister_netdevice()
at device dismantle.

unregister_netdevice: waiting for eth0 to become free. Usage count = 3

[PATCH 5.16 03/37] ASoC: sti: Fix deadlock via snd_pcm_stop_xrun() call

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 455c5653f50e10b4f460ef24e99f0044fbe3401c upstream.

This is essentially a revert of the commit dc865fb9e7c2 ("ASoC: sti:
Use snd_pcm_stop_xrun() helper"), which converted the manual
snd_pcm_stop() calls with snd_pcm_stop_xrun().

The commit above introduced a deadlock as snd_pcm_stop_xrun() itself
takes the PCM stream lock while the caller already holds it.  Since
the conversion was done only for consistency reason and the open-call
with snd_pcm_stop() to the XRUN state is a correct usage, let's revert
the commit back as the fix.

[PATCH 5.16 04/37] ALSA: oss: Fix PCM OSS buffer allocation overflow

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit efb6402c3c4a7c26d97c92d70186424097b6e366 upstream.

We've got syzbot reports hitting INT_MAX overflow at vmalloc()
allocation that is called from snd_pcm_plug_alloc().  Although we
apply the restrictions to input parameters, it's based only on the
hw_params of the underlying PCM device.  Since the PCM OSS layer
allocates a temporary buffer for the data conversion, the size may
become unexpectedly large when more channels or higher rates is given;
in the reported case, it went over INT_MAX, hence it hits WARN_ON().

This patch is an attempt to avoid such an overflow and an allocation
for too large buffers.  First off, it adds the limit of 1MB as the
upper bound for period bytes.  This must be large enough for all use
cases, and we really don't want to handle a larger temporary buffer
than this size.  The size check is performed at two places, where the
original period bytes is calculated and where the plugin buffer size
is calculated.

In addition, the driver uses array_size() and array3_size() for
multiplications to catch overflows for the converted period size and
buffer bytes.

[PATCH 5.16 05/37] ALSA: usb-audio: add mapping for new Corsair Virtuoso SE

[Greg Kroah-Hartman]

From: Reza Jahanbakhshi <reza.jahanbakhshi@gmail.com>

commit cd94df1795418056a19ff4cb44eadfc18ac99a57 upstream.

New device id for Corsair Virtuoso SE RGB Wireless that currently is not
in the mixer_map. This entry in the mixer_map is necessary in order to
label its mixer appropriately and allow userspace to pick the correct
volume controls. For instance, my own Corsair Virtuoso SE RGB Wireless
headset has this new ID and consequently, the sidetone and volume are not
 working correctly without this change.

[PATCH 5.16 10/37] ALSA: pcm: Fix races among concurrent hw_params and hw_free calls

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 92ee3c60ec9fe64404dc035e7c41277d74aa26cb upstream.

Currently we have neither proper check nor protection against the
concurrent calls of PCM hw_params and hw_free ioctls, which may result
in a UAF.  Since the existing PCM stream lock can't be used for
protecting the whole ioctl operations, we need a new mutex to protect
those racy calls.

This patch introduced a new mutex, runtime->buffer_mutex, and applies
it to both hw_params and hw_free ioctl code paths.  Along with it, the
both functions are slightly modified (the mmap_count check is moved
into the state-check block) for code simplicity.

[PATCH 5.16 11/37] ALSA: pcm: Fix races among concurrent read/write and buffer changes

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit dca947d4d26dbf925a64a6cfb2ddbc035e831a3d upstream.

In the current PCM design, the read/write syscalls (as well as the
equivalent ioctls) are allowed before the PCM stream is running, that
is, at PCM PREPARED state.  Meanwhile, we also allow to re-issue
hw_params and hw_free ioctl calls at the PREPARED state that may
change or free the buffers, too.  The problem is that there is no
protection against those mix-ups.

This patch applies the previously introduced runtime->buffer_mutex to
the read/write operations so that the concurrent hw_params or hw_free
call can no longer interfere during the operation.  The mutex is
unlocked before scheduling, so we don't take it too long.

From: Jordy Zomer <jordy@pwning.systems>

commit 4fbcc1a4cb20fe26ad0225679c536c80f1648221 upstream.

It appears that there are some buffer overflows in EVT_TRANSACTION.
This happens because the length parameters that are passed to memcpy
come directly from skb->data and are not guarded in any way.

[PATCH 5.16 13/37] net: ipv6: fix skb_over_panic in __ip6_append_data

[Greg Kroah-Hartman]

From: Tadeusz Struk <tadeusz.struk@linaro.org>

commit 5e34af4142ffe68f01c8a9acae83300f8911e20c upstream.

Syzbot found a kernel bug in the ipv6 stack:
LINK: https://syzkaller.appspot.com/bug?id=205d6f11d72329ab8d62a610c44c5e7e25415580
The reproducer triggers it by sending a crafted message via sendmmsg()
call, which triggers skb_over_panic, and crashes the kernel:

skbuff: skb_over_panic: text:ffffffff84647fb4 len:65575 put:65575
head:ffff888109ff0000 data:ffff888109ff0088 tail:0x100af end:0xfec0
dev:<NULL>

Update the check that prevents an invalid packet with MTU equal
to the fregment header size to eat up all the space for payload.

The reproducer can be found here:

[PATCH 5.16 14/37] tpm: Fix error handling in async work

[Greg Kroah-Hartman]

From: Tadeusz Struk <tstruk@gmail.com>

commit 2e8e4c8f6673247e22efc7985ce5497accd16f88 upstream.

When an invalid (non existing) handle is used in a TPM command,
that uses the resource manager interface (/dev/tpmrm0) the resource
manager tries to load it from its internal cache, but fails and
the tpm_dev_transmit returns an -EINVAL error to the caller.
The existing async handler doesn't handle these error cases
currently and the condition in the poll handler never returns
mask with EPOLLIN set.
The result is that the poll call blocks and the application gets stuck
until the user_read_timer wakes it up after 120 sec.
Change the tpm_dev_async_work function to handle error conditions

[PATCH 5.16 15/37] ALSA: pcm: Fix races among concurrent prepare and hw_params/hw_free calls

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 3c3201f8c7bb77eb53b08a3ca8d9a4ddc500b4c0 upstream.

Like the previous fixes to hw_params and hw_free ioctl races, we need
to paper over the concurrent prepare ioctl calls against hw_params and
hw_free, too.

This patch implements the locking with the existing
runtime->buffer_mutex for prepare ioctls.  Unlike the previous case
for snd_pcm_hw_hw_params() and snd_pcm_hw_free(), snd_pcm_prepare() is
performed to the linked streams, hence the lock can't be applied
simply on the top.  For tracking the lock in each linked substream, we
modify snd_pcm_action_group() slightly and apply the buffer_mutex for
the case stream_lock=false (formerly there was no lock applied)
there.

[PATCH 5.16 16/37] ALSA: pcm: Fix races among concurrent prealloc proc writes

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 69534c48ba8ce552ce383b3dfdb271ffe51820c3 upstream.

We have no protection against concurrent PCM buffer preallocation
changes via proc files, and it may potentially lead to UAF or some
weird problem.  This patch applies the PCM open_mutex to the proc
write operation for avoiding the racy proc writes and the PCM stream
open (and further operations).

[PATCH 5.16 17/37] ALSA: pcm: Add stream lock during PCM reset ioctl operations

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 1f68915b2efd0d6bfd6e124aa63c94b3c69f127c upstream.

snd_pcm_reset() is a non-atomic operation, and it's allowed to run
during the PCM stream running.  It implies that the manipulation of
hw_ptr and other parameters might be racy.

This patch adds the PCM stream lock at appropriate places in
snd_pcm_*_reset() actions for covering that.

[PATCH 5.16 18/37] ALSA: usb-audio: Add mute TLV for playback volumes on RODE NT-USB

From: Lars-Peter Clausen <lars@metafoo.de>

commit 0f306cca42fe879694fb5e2382748c43dc9e0196 upstream.

For the RODE NT-USB the lowest Playback mixer volume setting mutes the
audio output. But it is not reported as such causing e.g. PulseAudio to
accidentally mute the device when selecting a low volume.

Fix this by applying the existing quirk for this kind of issue when the
device is detected.

[PATCH 5.16 20/37] ALSA: pci: fix reading of swapped values from pcmreg in AC97 codec

[Greg Kroah-Hartman]

From: Giacomo Guiduzzi <guiduzzi.giacomo@gmail.com>

commit 17aaf0193392cb3451bf0ac75ba396ec4cbded6e upstream.

Tests 72 and 78 for ALSA in kselftest fail due to reading
inconsistent values from some devices on a VirtualBox
Virtual Machine using the snd_intel8x0 driver for the AC'97
Audio Controller device.
Taking for example test number 72, this is what the test reports:
"Surround Playback Volume.0 expected 1 but read 0, is_volatile 0"
"Surround Playback Volume.1 expected 0 but read 1, is_volatile 0"
These errors repeat for each value from 0 to 31.

Taking a look at these error messages it is possible to notice
that the written values are read back swapped.
When the write is performed, these values are initially stored in
an array used to sanity-check them and write them in the pcmreg
array. To write them, the two one-byte values are packed together
in a two-byte variable through bitwise operations: the first
value is shifted left by one byte and the second value is stored in the
right byte through a bitwise OR. When reading the values back,
right shifts are performed to retrieve the previously stored
bytes. These shifts are executed in the wrong order, thus
reporting the values swapped as shown above.

This patch fixes this mistake by reversing the read
operations' order.

[PATCH 5.16 21/37] drivers: net: xgene: Fix regression in CRC stripping

[Greg Kroah-Hartman]

From: Stephane Graber <stgraber@ubuntu.com>

commit e9e6faeafaa00da1851bcf47912b0f1acae666b4 upstream.

All packets on ingress (except for jumbo) are terminated with a 4-bytes
CRC checksum. It's the responsability of the driver to strip those 4
bytes. Unfortunately a change dating back to March 2017 re-shuffled some
code and made the CRC stripping code effectively dead.

This change re-orders that part a bit such that the datalen is
immediately altered if needed.

  ACPI Error: Unsupported address space: 0x20 (*/hwregs-*)
  ACPI Error: AE_SUPPORT, Unable to initialize fixed events (*/evevent-*)
  ACPI: Unable to start ACPI Interpreter

This leaves the ACPI implementation in such a broken state that subsequent
kernel subsystem initialisations go wrong, resulting in among others
mismapped PCI memory, SATA and USB enumeration failures, and freezes.

As this is an older embedded platform that will likely never see any BIOS
updates to address this issue and its default shipping OS only complies to
ACPI 1.0, work around this by forcing `acpi=rsdt`. This patch, applied on
top of Linux 5.10.102, was confirmed on real hardware to fix the issue.

[PATCH 5.16 25/37] ACPI: battery: Add device HID and quirk for Microsoft Surface Go 3

[Greg Kroah-Hartman]

From: Maximilian Luz <luzmaximilian@gmail.com>

commit 7dacee0b9efc8bd061f097b1a8d4daa6591af0c6 upstream.

For some reason, the Microsoft Surface Go 3 uses the standard ACPI
interface for battery information, but does not use the standard PNP0C0A
HID. Instead it uses MSHW0146 as identifier. Add that ID to the driver
as this seems to work well.

Additionally, the power state is not updated immediately after the AC
has been (un-)plugged, so add the respective quirk for that.

[PATCH 5.16 26/37] ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNU

[Greg Kroah-Hartman]

From: Werner Sembach <wse@tuxedocomputers.com>

commit c844d22fe0c0b37dc809adbdde6ceb6462c43acf upstream.

Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working
native and video interface. However the default detection mechanism first
registers the video interface before unregistering it again and switching
to the native interface during boot. This results in a dangling SBIOS
request for backlight change for some reason, causing the backlight to
switch to ~2% once per boot on the first power cord connect or disconnect
event. Setting the native interface explicitly circumvents this buggy
behaviour by avoiding the unregistering process.

[PATCH 5.16 27/37] crypto: qat - disable registration of algorithms

[Greg Kroah-Hartman]

From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>

commit 8893d27ffcaf6ec6267038a177cb87bcde4dd3de upstream.

The implementations of aead and skcipher in the QAT driver do not
support properly requests with the CRYPTO_TFM_REQ_MAY_BACKLOG flag set.
If the HW queue is full, the driver returns -EBUSY but does not enqueue
the request.
This can result in applications like dm-crypt waiting indefinitely for a
completion of a request that was never submitted to the hardware.

To avoid this problem, disable the registration of all crypto algorithms
in the QAT driver by setting the number of crypto instances to 0 at
configuration time.

[PATCH 5.16 31/37] rcu: Dont deboost before reporting expedited quiescent state

[Greg Kroah-Hartman]

From: Paul E. McKenney <paulmck@kernel.org>

commit 10c535787436d62ea28156a4b91365fd89b5a432 upstream.

Currently rcu_preempt_deferred_qs_irqrestore() releases rnp->boost_mtx
before reporting the expedited quiescent state.  Under heavy real-time
load, this can result in this function being preempted before the
quiescent state is reported, which can in turn prevent the expedited grace
period from completing.  Tim Murray reports that the resulting expedited
grace periods can take hundreds of milliseconds and even more than one
second, when they should normally complete in less than a millisecond.

This was fine given that there were no particular response-time
constraints for synchronize_rcu_expedited(), as it was designed
for throughput rather than latency.  However, some users now need
sub-100-millisecond response-time constratints.

This patch therefore follows Neeraj's suggestion (seconded by Tim and
by Uladzislau Rezki) of simply reversing the two operations.

[PATCH 5.16 32/37] uaccess: fix integer overflow on access_ok()

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@arndb.de>

commit 222ca305c9fd39e5ed8104da25c09b2b79a516a8 upstream.

Three architectures check the end of a user access against the
address limit without taking a possible overflow into account.
Passing a negative length or another overflow in here returns
success when it should not.

Use the most common correct implementation here, which optimizes
for a constant 'size' argument, and turns the common case into a
single comparison.

[PATCH 5.16 33/37] mac80211: fix potential double free on mesh join

[Greg Kroah-Hartman]

From: Linus Lüssing <ll@simonwunderlich.de>

commit 4a2d4496e15ea5bb5c8e83b94ca8ca7fb045e7d3 upstream.

While commit 6a01afcf8468 ("mac80211: mesh: Free ie data when leaving
mesh") fixed a memory leak on mesh leave / teardown it introduced a
potential memory corruption caused by a double free when rejoining the
mesh:

  ieee80211_leave_mesh()
  -> kfree(sdata->u.mesh.ie);
  ...
  ieee80211_join_mesh()
  -> copy_mesh_setup()
     -> old_ie = ifmsh->ie;
     -> kfree(old_ie);

This double free / kernel panics can be reproduced by using wpa_supplicant
with an encrypted mesh (if set up without encryption via "iw" then
ifmsh->ie is always NULL, which avoids this issue). And then calling:

  $ iw dev mesh0 mesh leave
  $ iw dev mesh0 mesh join my-mesh

Note that typically these commands are not used / working when using
wpa_supplicant. And it seems that wpa_supplicant or wpa_cli are going
through a NETDEV_DOWN/NETDEV_UP cycle between a mesh leave and mesh join
where the NETDEV_UP resets the mesh.ie to NULL via a memcpy of
default_mesh_setup in cfg80211_netdev_notifier_call, which then avoids
the memory corruption, too.

The issue was first observed in an application which was not using
wpa_supplicant but "Senf" instead, which implements its own calls to
nl80211.

Fixing the issue by removing the kfree()'ing of the mesh IE in the mesh
join function and leaving it solely up to the mesh leave to free the
mesh IE.

[PATCH 5.16 34/37] tpm: use try_get_ops() in tpm-space.c

[Greg Kroah-Hartman]

From: James Bottomley <James.Bottomley@HansenPartnership.com>

commit fb5abce6b2bb5cb3d628aaa63fa821da8c4600f9 upstream.

As part of the series conversion to remove nested TPM operations:

https://lore.kernel.org/all/20190205224723.19671-1-jarkko.sakkinen@linux.intel.com/

exposure of the chip->tpm_mutex was removed from much of the upper
level code.  In this conversion, tpm2_del_space() was missed.  This
didn't matter much because it's usually called closely after a
converted operation, so there's only a very tiny race window where the
chip can be removed before the space flushing is done which causes a
NULL deref on the mutex.  However, there are reports of this window
being hit in practice, so fix this by converting tpm2_del_space() to
use tpm_try_get_ops(), which performs all the teardown checks before
acquring the mutex.

[PATCH 5.16 35/37] wcn36xx: Differentiate wcn3660 from wcn3620

[Greg Kroah-Hartman]

From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>

commit 98d504a82cc75840bec8e3c6ae0e4f411921962b upstream.

The spread of capability between the three WiFi silicon parts wcn36xx
supports is:

wcn3620 - 802.11 a/b/g
wcn3660 - 802.11 a/b/g/n
wcn3680 - 802.11 a/b/g/n/ac

We currently treat wcn3660 as wcn3620 thus limiting it to 2GHz channels.
Fix this regression by ensuring we differentiate between all three parts.

[PATCH 5.16 36/37] m68k: fix access_ok for coldfire

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@arndb.de>

commit 26509034bef198525d5936c116cbd0c3fa491c0b upstream.

While most m68k platforms use separate address spaces for user
and kernel space, at least coldfire does not, and the other
ones have a TASK_SIZE that is less than the entire 4GB address
range.

Using the default implementation of __access_ok() stops coldfire
user space from trivially accessing kernel memory.

[PATCH 5.16 37/37] nds32: fix access_ok() checks in get/put_user

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@arndb.de>

commit 8926d88ced46700bf6117ceaf391480b943ea9f4 upstream.

The get_user()/put_user() functions are meant to check for
access_ok(), while the __get_user()/__put_user() functions
don't.

This broke in 4.19 for nds32, when it gained an extraneous
check in __get_user(), but lost the check it needs in
__put_user().
