commit 21c02e8272 upstream.
Recently, during a debugging session using local MPTCP connections, I
noticed MPJoinAckHMacFailure was not zero on the server side. The
counter was in fact incremented when the PM rejected new subflows,
because the 'subflow' limit was reached.
The fix is easy, simply dissociating the two cases: only the HMAC
validation check should increase MPTCP_MIB_JOINACKMAC counter.

commit 443041deb5 upstream.
When testing valkey benchmark tool with MPTCP, the kernel panics in
'mptcp_can_accept_new_subflow' because subflow_req->msk is NULL.
Call trace:
mptcp_can_accept_new_subflow (./net/mptcp/subflow.c:63 (discriminator 4)) (P)

...
According to the debug log, the same req received two SYN-ACK in a very
short time, very likely because the client retransmits the syn ack due
to multiple reasons.
Even if the packets are transmitted with a relevant time interval, they
can be processed by the server on different CPUs concurrently). The
'subflow_req->msk' ownership is transferred to the subflow the first,
and there will be a risk of a null pointer dereference here.
This patch fixes this issue by moving the 'subflow_req->msk' under the
`own_req == true` conditional.
Note that the !msk check in subflow_hmac_valid() can be dropped, because
the same check already exists under the own_req mpj branch where the
code has been moved to.

commit 8b46fdaea8 upstream.
The split_sg_phys function was incorrectly setting the offsets of all
scatterlist entries (except the first) to 0. Only the first scatterlist
entry's offset and length needs to be modified to account for the skip.
Setting the rest entries' offsets to 0 could lead to incorrect data
access.
I am using this function in a crypto driver that I'm currently developing
(not yet sent to mailing list). During testing, it was observed that the
output scatterlists (except the first one) contained incorrect garbage
data.
I narrowed this issue down to the call of sg_split(). Upon debugging
inside this function, I found that this resetting of offset is the cause
of the problem, causing the subsequent scatterlists to point to incorrect
memory locations in a page. By removing this code, I am obtaining
expected data in all the split output scatterlists. Thus, this was indeed
causing observable runtime effects!
This patch removes the offending code, ensuring that the page offsets in
the input scatterlist are preserved in the output scatterlist.

that nr_unused_locks != 0 but no unused lock class is active in the
system, and when `cat /proc/lockdep_stats`, a WARN_ON() will

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.

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.

commit 6afdc60ec3 upstream.
Smatch noticed that inode_getblk() can return 1 on successful mapping of
a block instead of expected 0 after commit b405c1e58b ("udf: refactor
udf_next_aext() to handle error"). This could confuse some of the
callers and lead to strange failures (although the one reported by
Smatch in udf_mkdir() is impossible to trigger in practice). Fix the
return value of inode_getblk().

commit a6097e0a54 upstream.
create_user_mr() has correct code to count the number of null keys
used to fill in a hole for the memory map. However, fill_indir()
does not follow the same to cap the range up to the 1GB limit
correspondingly. Fill in more null keys for the gaps in between,
so that null keys are correctly populated.

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.

'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

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 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.

commit d00c0c4105 upstream.
Since the new_metric and last_hop_metric variables can reach
the MAX_METRIC(0xffffffff) value, an integer overflow may occur
when multiplying them by 10/9. It can lead to incorrect behavior.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.
Fixes: a8d418d9ac ("mac80211: mesh: only switch path when new metric is at least 10% better")
