[ Upstream commit d68886bae7 ]
The data type of loca_last_write_offset is newoffset4 and is switched
on a boolean value, no_newoffset, that indicates if a previous write
occurred or not. If no_newoffset is FALSE, an offset is not given.
This means that client does not try to update the file size. Thus,
server should not try to calculate new file size and check if it fits
into the segment range. See RFC 8881, section 12.5.4.2.
Sometimes the current incorrect logic may cause clients to hang when
trying to sync an inode. If layoutcommit fails, the client marks the
inode as dirty again.

[ Upstream commit f963cf2b91 ]
When pNFS client in the block or scsi layout mode sends layoutcommit
to MDS, a variable length array of modified extents is supplied within
the request. This patch allows the server to accept such extent arrays
if they do not fit within single memory page.
The issue can be reproduced when writing to a 1GB file using FIO with
O_DIRECT, 4K block and large I/O depth without preallocation of the
file. In this case, the server returns NFSERR_BADXDR to the client.

This patch adds the correct functions to handle the deviceid4 structure

Update inv_icm42600_disable_vddio_reg() to only disable the regulator if
the device is not suspended i.e. powered-down, preventing unbalanced

[ Upstream commit 284fb19a3f ]
PLL lockup and O_CMN_READY assertion can only happen after common state
machine gets enabled by programming DPHY_CMN_SSM register, but driver was
polling them before the common state machine was enabled which is
incorrect. This is as per the DPHY initialization sequence as mentioned in
J721E TRM [1] at section "12.7.2.4.1.2.1 Start-up Sequence Timing Diagram".
It shows O_CMN_READY polling at the end after common configuration pin
setup where the common configuration pin setup step enables state machine
as referenced in "Table 12-1533. Common Configuration-Related Setup
mentions state machine"
To fix this :
- Add new function callbacks for polling on PLL lock and O_CMN_READY
assertion.
- As state machine and clocks get enabled in power_on callback only, move
the clock related programming part from configure callback to power_on
callback and poll for the PLL lockup and O_CMN_READY assertion after state
machine gets enabled.
- The configure callback only saves the PLL configuration received from the
client driver which will be applied later on in power_on callback.
- Add checks to ensure configure is called before power_on and state
machine is in disabled state before power_on callback is called.
- Disable state machine in power_off so that client driver can re-configure
the PLL by following up a power_off, configure, power_on sequence.

[ Upstream commit e747883c7d ]
When mounting file systems with a log that was dirtied on i386 on
other architectures or vice versa, log recovery is unhappy:
[ 11.068052] XFS (vdb): Torn write (CRC failure) detected at log block 0x2. Truncating head block from 0xc.
This is because the CRCs generated by i386 and other architectures
always diff. The reason for that is that sizeof(struct xlog_rec_header)
returns different values for i386 vs the rest (324 vs 328), because the
struct is not sizeof(uint64_t) aligned, and i386 has odd struct size
alignment rules.
This issue goes back to commit 13cdc853c519 ("Add log versioning, and new
super block field for the log stripe") in the xfs-import tree, which
adds log v2 support and the h_size field that causes the unaligned size.
At that time it only mattered for the crude debug only log header
checksum, but with commit 0e446be448 ("xfs: add CRC checks to the log")
it became a real issue for v5 file system, because now there is a proper
CRC, and regular builds actually expect it match.
Fix this by allowing checksums with and without the padding.

[ Upstream commit 5a869d0177 ]
With TLS enabled, records that are encrypted and appended to TLS TX
list can fail to see a retry if the underlying TCP socket is busy, for
example, hitting an EAGAIN from tcp_sendmsg_locked(). This is not known
to the NVMe TCP driver, as the TLS layer successfully generated a record.
Typically, the TLS write_space() callback would ensure such records are
retried, but in the NVMe TCP Host driver, write_space() invokes
nvme_tcp_write_space(). This causes a partially sent record in the TLS TX
list to timeout after not being retried.
This patch fixes the above by calling queue->write_space(), which calls
into the TLS layer to retry any pending records.

[ Upstream commit 2b4eda7bf7 ]
Stress testing the audio jack hotplug handling on a few Steam Deck units
revealed that the debounce circuit is responsible for having a negative
impact on the detection reliability, e.g. in some cases the ejection
interrupt is not fired, while in other instances it goes into a kind of
invalid state and generates a flood of misleading interrupts.
Add new entries to the DMI table introduced via commit 1bc40efdaf
("ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect")
and extend the quirk logic to allow bypassing the debounce circuit used
for jack detection on Valve Steam Deck LCD and OLED models.
While at it, rename existing NAU8821_JD_ACTIVE_HIGH quirk bitfield to
NAU8821_QUIRK_JD_ACTIVE_HIGH. This should help improve code readability
by differentiating from similarly named register bits.

[ Upstream commit 9273aa85b3 ]
Instead of adding yet another utility function for dealing with the
interrupt clearing register, generalize nau8821_int_status_clear_all()
by renaming it to nau8821_irq_status_clear(), whilst introducing a
second parameter to allow restricting the operation scope to a single
interrupt instead of the whole range of active IRQs.
While at it, also fix a spelling typo in the comment block.
Note this is mainly a prerequisite for subsequent patches aiming to
address some deficiencies in the implementation of the interrupt
handler. Thus the presence of the Fixes tag below is intentional, to
facilitate backporting.

[ Upstream commit 6e54919cb5 ]
The microphone detection work scheduled by a prior jack insertion
interrupt may still be in a pending state or under execution when a jack
ejection interrupt has been fired.
This might lead to a racing condition or nau8821_jdet_work() completing
after nau8821_eject_jack(), which will override the currently
disconnected state of the jack and incorrectly report the headphone or
the headset as being connected.
Cancel any pending jdet_work or wait for its execution to finish before
attempting to handle the ejection interrupt.
Proceed similarly before launching the eject handler as a consequence of
detecting an invalid insert interrupt.

When adding a kprobe such as "p:probe/tcp_sendmsg _text+15392192",
arch_check_kprobe would start iterating all instructions starting from
_text until the probed address. Not only is this very inefficient, but
literal values in there (e.g. left by function patching) are
misinterpreted in a way that causes a desync.
Fix this by doing it like x86: start the iteration at the closest

[ Upstream commit bb642e2d30 ]
For queue-depth I/O policy, this patch fixes unbalanced I/Os across
nvme multipaths.
Issue Description:
The RETRY disposition incorrectly increments ns->ctrl->nr_active
counter and reinitializes iostat start-time. In such cases nr_active
counter never goes back to zero until that path disconnects and
reconnects.
Such a path is not chosen for new I/Os if multiple RETRY cases on a given
a path cause its queue-depth counter to be artificially higher compared
to other paths. This leads to unbalanced I/Os across paths.
The patch skips incrementing nr_active if NVME_MPATH_CNT_ACTIVE is already
set. And it skips restarting io stats if NVME_MPATH_IO_STATS is already set.

[ Upstream commit e07e10ae83 ]
Currently the Panthor driver needs the GPU to be powered down
between suspend and resume. If this is not done, then the
MCU_CONTROL register will be preserved as AUTO, which again will
cause a premature FW boot on resume. The FW will go directly into
fatal state in this case.
This case needs to be handled as there is no guarantee that the
GPU will be powered down after the suspend callback on all platforms.
The fix is to call panthor_fw_stop() in "pre-reset" path to ensure
the MCU_CONTROL register is cleared (set DISABLE). This matches
well with the already existing call to panthor_fw_start() from the
"post-reset" path.

[ Upstream commit 7f846c65ca ]
With async crypto, we rely on tx_work to actually transmit records
once encryption completes. But while send() is running, both the
tx_lock and socket lock are held, so tx_work_handler cannot process
the queue of encrypted records, and simply reschedules itself. During
a large send(), this could last a long time, and use a lot of memory.
Transmit any pending encrypted records before restarting the main
loop of tls_sw_sendmsg_locked.

[ Upstream commit b6fe4c29bb ]
When userspace wants to send a non-DATA record (via the
TLS_SET_RECORD_TYPE cmsg), we need to send any pending data from a
previous MSG_MORE send() as a separate DATA record. If that DATA record
is encrypted asynchronously, tls_handle_open_record will return
-EINPROGRESS. This is currently treated as an error by
tls_process_cmsg, and it will skip setting record_type to the correct
value, but the caller (tls_sw_sendmsg_locked) handles that return
value correctly and proceeds with sending the new message with an
incorrect record_type (DATA instead of whatever was requested in the
cmsg).
Always set record_type before handling the open record. If
tls_handle_open_record returns an error, record_type will be
ignored. If it succeeds, whether with synchronous crypto (returning 0)
or asynchronous (returning -EINPROGRESS), the caller will proceed
correctly.

If we hit an error during the main loop of tls_sw_sendmsg_locked (eg
failed allocation), we jump to send_end and immediately
return. Previous iterations may have queued async encryption requests
that are still pending. We should wait for those before returning, as
we could otherwise be reading from memory that userspace believes
we're not using anymore, which would be a sort of use-after-free.
This is similar to what tls_sw_recvmsg already does: failures during
the main loop jump to the "wait for async" code, not straight to the
unlock/return.

we may end up sending less, for example when splicing: if we're
getting the data from small fragments of memory, we may fill up all
the slots in the skmsg with less data than expected.
In this case, we need to trim the encrypted message to only the length
we actually need, to avoid pushing uninitialized bytes down the
