message is possible output when system enters suspend and while
transferring data, because clearing TIE bit in SCSCR is not able to
stop any dmaengine transfer.

Note that this driver has already used some #ifdef in the .c file
so that this patch also uses #ifdef to fix the issue. Otherwise,
build errors happens if the CONFIG_SERIAL_SH_SCI_DMA is disabled.

commit 421a26f3d7a7c3ca43f3a9dc0f3cb0f562d5bd95 upstream.
The ltr559 chip uses only the lowest bit of the ALS_CONTR register to
configure between active and stand-by mode. In the original driver
BIT(1) is used, which does a software reset instead.
This patch fixes the problem by using BIT(0) as als_mode_active for
the ltr559 chip.

commit 2ac0b029a04b673ce83b5089368f467c5dca720c upstream.
The regmap is configured for 8 bit registers, uses a RB-Tree cache and
marks several registers as volatile (i.e. do not cache).
The ALS and PS data registers in the chip are 16 bit wide and spans
two regmap registers. In the current driver only the base register is
marked as volatile, resulting in the upper register only read once.
Further the data sheet notes:
| When the I2C read operation starts, all four ALS data registers are
| locked until the I2C read operation of register 0x8B is completed.
Which results in the registers never update after the 2nd read.
This patch fixes the problem by marking the upper 8 bits of the ALS
and PS registers as volatile, too.

commit c749d8c018daf5fba6dfac7b6c5c78b27efd7d65 upstream.
Currently css_wait_for_slow_path() gets called inside the chp->lock.
The path-verification-loop of slowpath inside this lock could lead to
deadlock as reported by the lockdep validator.
The ccw_device_get_chp_desc() during the instance of a device-set-online
would try to acquire the same 'chp->lock' to read the chp->desc.
The instance of this function can get called from multiple scenario,
like probing or setting-device online manually. This could, in some
corner-cases lead to the deadlock.
lockdep validator reported this as,
CPU0 CPU1

lock(&chp->lock);
lock(kn->active#43);
lock(&chp->lock);
lock((wq_completion)cio);
The chp->lock was introduced to serialize the access of struct
channel_path. This lock is not needed for the css_wait_for_slow_path()
function, so invoke the slow-path function outside this lock.

LLVM does not emit optimal byteswap assembly, which results in high
stack usage in kvmhv_enter_nested_guest() due to the inlining of
byteswap_pt_regs(). With LLVM 12.0.0:
arch/powerpc/kvm/book3s_hv_nested.c:289:6: error: stack frame size of
2512 bytes in function 'kvmhv_enter_nested_guest' [-Werror,-Wframe-larger-than=]

1 error generated.
While this gets fixed in LLVM, mark byteswap_pt_regs() as
noinline_for_stack so that it does not get inlined and break the build
due to -Werror by default in arch/powerpc/. Not inlining saves
approximately 800 bytes with LLVM 12.0.0:

commit 4c1daba15c209b99d192f147fea3dade30f72ed2 upstream.
With global filtering, we only allow an event to be scheduled if its
filter settings exactly match those of any existing events, therefore
it is pointless to reapply the filter in that case. Much worse, though,
is that in doing that we trample the event type of counter 0 if it's
already active, and never touch the appropriate PMEVTYPERn so the new
event is likely not counting the right thing either. Don't do that.

Privileged delegreturn task is queued to privileged list because all
the slots are assigned. If there has no enough slot to wake up the
non-privileged batch tasks(session less than 8 slot), then the privileged
delegreturn task maybe lost waked up because the found out task can't
get slot since the session is on draining.
So we should treate the privileged task as the emergency task, and
execute it as for as we can.

can_rx_register() callbacks may be called concurrently to the call to
can_rx_unregister(). The callbacks and callback data, though, are
protected by RCU and the struct sock reference count.
So the callback data is really attached to the life of sk, meaning
that it should be released on sk_destruct. However, bcm_remove_op()
calls tasklet_kill(), and RCU callbacks may be called under RCU
softirq, so that cannot be used on kernels before the introduction of
HRTIMER_MODE_SOFT.
However, bcm_rx_handler() is called under RCU protection, so after
calling can_rx_unregister(), we may call synchronize_rcu() in order to
wait for any RCU read-side critical sections to finish. That is,
bcm_rx_handler() won't be called anymore for those ops. So, we only
free them, after we do that synchronize_rcu().

commit d8ac76cdd1755b21e8c008c28d0b7251c0b14986 upstream.
During an incremental send operation, when processing the new references
for the current inode, we might send an unlink operation for another inode
that has a conflicting path and has more than one hard link. However this
path was computed and cached before we processed previous new references
for the current inode. We may have orphanized a directory of that path
while processing a previous new reference, in which case the path will
be invalid and cause the receiver process to fail.
The following reproducer triggers the problem and explains how/why it
happens in its comments:
$ cat test-send-unlink.sh

# This is because when send is processing inode 257, it generates the

# snapshot, and caches that path.
#
# Later when processing inode 258, it first processes its new reference
# that has the path of "/A", which results in orphanizing inode 260
# because there is a a path collision. This results in issuing a rename
# operation from "/A" to "/o260-6-0".
#
# Finally when processing the new reference "B/hard_link" for inode 258,
# it notices that it collides with inode 259 (not yet processed, because
# it has a higher inode number), since that inode has the name
# "hard_link" under the directory inode 260. It also checks that inode
# 259 has two hardlinks, so it decides to issue a unlink operation for
# the name "hard_link" for inode 259. However the path passed to the
# unlink operation is "/A/hard_link", which is incorrect since currently
# "/A" does not exists, due to the orphanization of inode 260 mentioned
# before. The path is incorrect because it was computed and cached
# before the orphanization. This results in the receiver to fail with
# the above error.
btrfs receive -f /tmp/snap2.send $MNT

When running the test, it fails like this:

ERROR: unlink A/hard_link failed: No such file or directory
Fix this by recomputing a path before issuing an unlink operation when
processing the new references for the current inode if we previously
have orphanized a directory.

commit f8f84af5da9ee04ef1d271528656dac42a090d00 upstream.
Even though we validate user-provided inputs we then traverse past
validated data when applying the new map. The issue was originally
discovered by Murray McAllister with this simple POC (if the following
is executed by an unprivileged user it will instantly panic the system):
int main(void) {
int fd, ret;
unsigned int buffer[10000];
fd = open("/dev/input/js0", O_RDONLY);
if (fd == -1)
printf("Error opening file\n");
ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer);
printf("%d\n", ret);
}
The solution is to traverse internal buffer which is guaranteed to only
contain valid date when constructing the map.

commit d98e4d95411bbde2220a7afa38dcc9c14d71acbe upstream.
When checking the file name attribute, we want to ensure that it fits
within the bounds of ATTR_RECORD. To do this, we should check that (attr
record + file name offset + file name length) < (attr record + attr record
length).
However, the original check did not include the file name offset in the
calculation. This means that corrupted on-disk metadata might not caught
by the incorrect file name check, and lead to an invalid memory access.
An example can be seen in the crash report of a memory corruption error
found by Syzbot:
https://syzkaller.appspot.com/bug?id=a1a1e379b225812688566745c3e2f7242bffc246
Adding the file name offset to the validity check fixes this error and
passes the Syzbot reproducer test.

The device (32a7:0000 Heimann Sensor GmbH USB appset demo) claims to be
a CDC-ACM device in its descriptors but in fact is not. If it is run
with echo disabled it returns garbled data, probably due to something
that happens in the TTY layer. And when run with echo enabled (the
default), it will mess up the calibration data of the sensor the first
time any data is sent to the device.
In short, I had a bad time after connecting the sensor and trying to get
it to work. I hope blacklisting it in the cdc-acm driver will save
someone else a bit of trouble.

commit f8fbcdfb0665de60997d9746809e1704ed782bbc upstream.
Asus Zenbook 14 UM431D has two speaker pins and a headphone pin, and
the auto-parser ends up assigning the bass to the third DAC 0x06.
Although the tone comes out, it's inconvenient because this DAC has no
volume control unlike two other DACs.
For obtaining the volume control for the bass speaker, this patch
enforces the mapping to let both front and bass speaker pins sharing
the same DAC. It's not ideal but a little bit of improvement.
Since we've already applied the same workaround for another ASUS
machine, we just need to hook the chain to the existing quirk.

commit 785b6f29a795f109685f286b91e0250c206fbffb upstream.
The current way of the scarlett2 mixer code managing the
usb_mixer_elem_info object is wrong in two ways: it passes its
internal index to the head.id field, and the val_type field is
uninitialized. This ended up with the wrong execution at the resume
because a bogus unit id is passed wrongly. Also, in the later code
extensions, we'll have more mixer elements, and passing the index will
overflow the unit id size (of 256).
This patch corrects those issues. It introduces a new value type,
USB_MIXER_BESPOKEN, which indicates a non-standard mixer element, and
use this type for all scarlett2 mixer elements, as well as
initializing the fixed unit id 0 for avoiding the overflow.
