4b037851ed leds: rgb: leds-qcom-lpg: Fix calculation of best period Hi-Res PWMs
commit 2528eec7da upstream.

When determining the actual best period by looping through all
possible PWM configs, the resolution currently used is based on
bit shift value which is off-by-one above the possible maximum
PWM value allowed.

So subtract one from the resolution before determining the best
period so that the maximum duty cycle requested by the PWM user
won't result in a value above the maximum allowed by the selected
resolution.

5ae9e361e2 leds: rgb: leds-qcom-lpg: Fix pwm resolution max for Hi-Res PWMs
commit b7881eacc0 upstream.

Ideally, the requested duty cycle should never translate to a PWM
value higher than the selected resolution (PWM size), but currently the
best matched period is never reported back to the PWM consumer, so the
consumer will still be using the requested period which is higher than
the best matched one. This will result in PWM consumer requesting
duty cycle values higher than the allowed PWM value.

For example, a consumer might request a period of 5ms while the best
(closest) period the PWM hardware will do is 4.26ms. For this best
matched resolution, if the selected resolution is 8-bit wide, when
the consumer asks for a duty cycle of 5ms, the PWM value will be 300,
which is outside of what the resolution allows. This will happen with
all possible resolutions when selected.

Since for these Hi-Res PWMs, the current implementation is capping the PWM
value at a 15-bit resolution, even when lower resolutions are selected,
the value will be wrapped around by the HW internal logic to the selected
resolution.

Fix the issue by capping the PWM value to the maximum value allowed by
the selected resolution.

e94314b727 kbuild: exclude .rodata.(cst|str)* when building ranges
commit 87bb368d06 upstream.

The .rodata.(cst|str)* sections are often resized during the final
linking and since these sections do not cover actual symbols there is
no need to include them in the modules.builtin.ranges data.

When these sections were included in processing and resizing occurred,
modules were reported with ranges that extended beyond their true end,
causing subsequent symbols (in address order) to be associated with
the wrong module.

9eaec071f1 jbd2: remove wrong sb->s_sequence check
commit e6eff39dd0 upstream.

Journal emptiness is not determined by sb->s_sequence == 0 but rather by
sb->s_start == 0 (which is set a few lines above). Furthermore 0 is a
valid transaction ID so the check can spuriously trigger. Remove the
invalid WARN_ON.

e6bba32857 i3c: Add NULL pointer check in i3c_master_queue_ibi()
commit bd496a44f0 upstream.

The I3C master driver may receive an IBI from a target device that has not
been probed yet. In such cases, the master calls `i3c_master_queue_ibi()`
to queue an IBI work task, leading to "Unable to handle kernel read from
unreadable memory" and resulting in a kernel panic.

Typical IBI handling flow:
1. The I3C master scans target devices and probes their respective drivers.
2. The target device driver calls `i3c_device_request_ibi()` to enable IBI
   and assigns `dev->ibi = ibi`.
3. The I3C master receives an IBI from the target device and calls
   `i3c_master_queue_ibi()` to queue the target device driver’s IBI
   handler task.

However, since target device events are asynchronous to the I3C probe
sequence, step 3 may occur before step 2, causing `dev->ibi` to be `NULL`,
leading to a kernel panic.

Add a NULL pointer check in `i3c_master_queue_ibi()` to prevent accessing
an uninitialized `dev->ibi`, ensuring stability.

0327683c55 ima: limit the number of ToMToU integrity violations
commit a414016218 upstream.

Each time a file in policy, that is already opened for read, is opened
for write, a Time-of-Measure-Time-of-Use (ToMToU) integrity violation
audit message is emitted and a violation record is added to the IMA
measurement list.  This occurs even if a ToMToU violation has already
been recorded.

Limit the number of ToMToU integrity violations per file open for read.

Note: The IMA_MAY_EMIT_TOMTOU atomic flag must be set from the reader
side based on policy.  This may result in a per file open for read
ToMToU violation.

Since IMA_MUST_MEASURE is only used for violations, rename the atomic
IMA_MUST_MEASURE flag to IMA_MAY_EMIT_TOMTOU.

9a264e4a59 smb311 client: fix missing tcon check when mounting with linux/posix extensions
commit b365b9d404 upstream.

When mounting the same share twice, once with the "linux" mount parameter
(or equivalently "posix") and then once without (or e.g. with "nolinux"),
we were incorrectly reusing the same tree connection for both mounts.
This meant that the first mount of the share on the client, would
cause subsequent mounts of that same share on the same client to
ignore that mount parm ("linux" vs. "nolinux") and incorrectly reuse
the same tcon.

fbda9cac1b svcrdma: do not unregister device for listeners
commit 750037aa0a upstream.

On an rdma-capable machine, a start/stop/start and then on a stop of
a knfsd server would lead kref underflow warning because svc_rdma_free
would indiscriminately unregister the rdma device but a listening
transport never calls the rdma_rn_register() thus leading to kref
going down to 0 on the 1st stop of the server and on the 2nd stop
it leads to a problem.

a1dde7457d f2fs: fix to avoid atomicity corruption of atomic file
commit f098aeba04 upstream.

In the case of the following call stack for an atomic file,
FI_DIRTY_INODE is set, but FI_ATOMIC_DIRTIED is not subsequently set.

f2fs_file_write_iter
  f2fs_map_blocks
    f2fs_reserve_new_blocks
      inc_valid_block_count
        __mark_inode_dirty(dquot)
          f2fs_dirty_inode

If FI_ATOMIC_DIRTIED is not set, atomic file can encounter corruption
due to a mismatch between old file size and new data.

To resolve this issue, I changed to set FI_ATOMIC_DIRTIED when
FI_DIRTY_INODE is set. This ensures that FI_DIRTY_INODE, which was
previously cleared by the Writeback thread during the commit atomic, is
set and i_size is updated.

	size += map[i].size;
	move++;
}

'i' in this case could go down to -1, in which case sum of active entries
wouldn't exceed half the block size, but previous behaviour would also do
split in half if sum would exceed at the very last block, which in case of
having too many long name files in a single block could lead to
out-of-bounds access and following use-after-free.

a77955f770 bus: mhi: host: Fix race between unprepare and queue_buf
commit 0686a818d7 upstream.

A client driver may use mhi_unprepare_from_transfer() to quiesce
incoming data during the client driver's tear down. The client driver
might also be processing data at the same time, resulting in a call to
mhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs
after mhi_unprepare_from_transfer() has torn down the channel, a panic
will occur due to an invalid dereference leading to a page fault.

This occurs because mhi_gen_tre() does not verify the channel state
after locking it. Fix this by having mhi_gen_tre() confirm the channel
state is valid, or return error to avoid accessing deinitialized data.

commit 9a6f56762d upstream.

Fix deadlock in ivpu_ms_cleanup() by preventing runtime resume after

During a failure in runtime resume, a cold boot is executed, which
calls ivpu_ms_cleanup_all(). This function calls ivpu_ms_cleanup()
that acquires file_priv->ms_lock and causes the deadlock.

commit e5182305a5 upstream.

This patch adds the HP OMEN 16 Laptop xd000xx to enable mute led.
it uses ALC245_FIXUP_HP_MUTE_LED_COEFBIT with a slight modification
setting mute_led_coef.off to 0(it was set to 4 i guess
in that function) which i referred to your previous patch disscusion
https://bugzilla.kernel.org/show_bug.cgi?id=214735 .
i am not sure whether i can modify the current working function so i
added another version calling
ALC245_FIXUP_HP_MUTE_LED_V1_COEFBIT. and both works for me.

d2a2076d9c ASoC: qdsp6: q6asm-dai: fix q6asm_dai_compr_set_params error path
commit 7eccc86e90 upstream.

In case of attempts to compress playback something, for instance,
when audio routing is not set up correctly, the audio DSP is left in
inconsistent state because we are not doing the correct things in
the error path of q6asm_dai_compr_set_params().

So, when routing is not set up and compress playback is attempted
the following errors are present (simplified log):

q6routing routing: Routing not setup for MultiMedia-1 Session
q6asm-dai dais: Stream reg failed ret:-22
q6asm-dai dais: ASoC error (-22): at snd_soc_component_compr_set_params()
on 17300000.remoteproc:glink-edge:apr:service@7:dais

After setting the correct routing the compress playback will always fail:

q6asm-dai dais: cmd = 0x10db3 returned error = 0x9
q6asm-dai dais: DSP returned error[9]
q6asm-dai dais: q6asm_open_write failed
q6asm-dai dais: ASoC error (-22): at snd_soc_component_compr_set_params()
on 17300000.remoteproc:glink-edge:apr:service@7:dais

0x9 here means "Operation is already processed". The CMD_OPEN here was
sent the second time hence DSP responds that it was already done.

Turns out the CMD_CLOSE should be sent after the q6asm_open_write()
succeeded but something failed after that, for instance, routing
setup.

Fix this by slightly reworking the error path in
q6asm_dai_compr_set_params().

Tested on QRB5165 RB5 and SDM845 RB3 boards.

not. Add a flag signifying whether a request wants to post multiple

commit 1ebc8e1ef9 upstream.

Implement the workaround for erratum
  3.3 RGMII timing may be out of spec when transmit delay is enabled
for the 6320 family, which says:

  When transmit delay is enabled via Port register 1 bit 14 = 1, duty
  cycle may be out of spec. Under very rare conditions this may cause
  the attached device receive CRC errors.

91e1405088 mptcp: sockopt: fix getting freebind & transparent
commit e2f4ac7bab upstream.

When adding a socket option support in MPTCP, both the get and set parts
are supposed to be implemented.

IP(V6)_FREEBIND and IP(V6)_TRANSPARENT support for the setsockopt part
has been added a while ago, but it looks like the get part got
forgotten. It should have been present as a way to verify a setting has
been set as expected, and not to act differently from TCP or any other
socket types.

Everything was in place to expose it, just the last step was missing.
Only new code is added to cover these specific getsockopt(), that seems
safe.

1b4ecd033e mptcp: sockopt: fix getting IPV6_V6ONLY
commit 8c39633759 upstream.

When adding a socket option support in MPTCP, both the get and set parts
are supposed to be implemented.

IPV6_V6ONLY support for the setsockopt part has been added a while ago,
but it looks like the get part got forgotten. It should have been
present as a way to verify a setting has been set as expected, and not
to act differently from TCP or any other socket types.

Not supporting this getsockopt(IPV6_V6ONLY) blocks some apps which want
to check the default value, before doing extra actions. On Linux, the
default value is 0, but this can be changed with the net.ipv6.bindv6only
sysctl knob. On Windows, it is set to 1 by default. So supporting the
get part, like for all other socket options, is important.

Everything was in place to expose it, just the last step was missing.
Only new code is added to cover this specific getsockopt(), that seems
safe.

commit 035371c9e5 upstream.

The Wave5 521C variant does not support 10 bit decoding. When 10 bit
decoding support was added for the 515 variant, a section of the code
was removed which returned an error. This removal causes a timeout for
the 521 variant, which was discovered during HEVC 10-bit decoding tests.

6f77a6d2ea media: i2c: imx214: Rectify probe error handling related to runtime PM
commit ccc888d169 upstream.

There were multiple issues in the driver's probe function related to
error handling:

- Device's PM runtime status wasn't reverted to suspended on some errors
  in probe.

- Runtime PM was left enabled for the device on some probe errors.

- Device was left powered on if a probe failure happened or when it
  was removed when it was powered on.

- An extra pm_runtime_set_suspended() was issued in driver's remove
  function when the device was suspended.

Fix these bugs.
