ACPI / x86: Work around broken XSDT on Advantech DAC-BJ01 board
commit e702196bf85778f2c5527ca47f33ef2e2fca8297 upstream.
On this board the ACPI RSDP structure points to both a RSDT and an XSDT,
but the XSDT points to a truncated FADT. This causes all sorts of trouble
and usually a complete failure to boot after the following error occurs:
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.

ACPI: battery: Add device HID and quirk for Microsoft Surface Go 3
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.

ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNU
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.

ALSA: pci: fix reading of swapped values from pcmreg in AC97 codec
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.

ALSA: pcm: Add stream lock during PCM reset ioctl operations
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.

crypto: qat - disable registration of algorithms
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.

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.

llc: only change llc->dev when bind() succeeds
commit 2d327a79ee176930dc72c131a970c891d367c1dc upstream.
My latest patch, attempting to fix the refcount leak in a minimal
way turned out to add a new bug.
Whenever the bind operation fails before we attempt to grab
a reference count on a device, we might release the device refcount
of a prior successful bind() operation.
syzbot was not happy about this [1].
Note to stable teams:
Make sure commit b37a46683739 ("netdevice: add the case if dev is NULL")
is already present in your trees.

mac80211: fix potential double free on mesh join
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.

In rare cases the display is flipped or mirrored. This was observed more
often in a low temperature environment. A clean reset on init_display()
should help to get registers in a sane state.

thermal: int340x: fix memory leak in int3400_notify()
commit 3abea10e6a8f0e7804ed4c124bea2d15aca977c8 upstream.
It is easy to hit the below memory leaks in my TigerLake platform:
unreferenced object 0xffff927c8b91dbc0 (size 32):
comm "kworker/0:2", pid 112, jiffies 4294893323 (age 83.604s)
hex dump (first 32 bytes):
4e 41 4d 45 3d 49 4e 54 33 34 30 30 20 54 68 65 NAME=INT3400 The
72 6d 61 6c 00 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b a5 rmal.kkkkkkkkkk.

Fix it by calling kfree() accordingly.
