[ Upstream commit 9764401bf6f8a20eb11c2e78470f20fee91a9ea7 ]
Some broken device return wrong dwMaxPayloadTransferSize fields as
follows:
[ 218.632537] uvcvideo: Device requested 2752512 B/frame bandwidth.
[ 218.632598] uvcvideo: No fast enough alt setting for requested bandwidth.
When dwMaxPayloadTransferSize is greater than maxpsize, it will prevent
the camera from starting. So use the bandwidth of maxpsize.

[ Upstream commit 649c033711d7fd6e1d5d69e4cfc3fceca7de2867 ]
To implement VIDIOC_QUERYCTRL, we need to know the minimum, maximum,
step and flags of the control. For some of the controls, this involves
querying the actual hardware.
Some non-compliant cameras produce errors when we query them. These
error can be triggered every time, sometimes, or when other controls do
not have the "right value". Right now, we populate that error to userspace.
When an error happens, the v4l2 framework does not copy the v4l2_queryctrl
struct to userspace. Also, userspace apps are not ready to handle any
other error than -EINVAL.
One of the main usecases of VIDIOC_QUERYCTRL is enumerating the controls
of a device. This is done using the V4L2_CTRL_FLAG_NEXT_CTRL flag. In
that usecase, a non-compliant control will make it almost impossible to
enumerate all controls of the device.
A control with an invalid max/min/step/flags is better than non being
able to enumerate the rest of the controls.
This patch:
- Retries for an extra attempt to read the control, to avoid spurious
errors. More attempts do not seem to produce better results in the
tested hardware.
- Makes VIDIOC_QUERYCTRL return 0 for -EIO errors.
- Introduces a warning in dmesg so we can have a trace of what has happened
and sets the V4L2_CTRL_FLAG_DISABLED.
- Makes sure we keep returning V4L2_CTRL_FLAG_DISABLED for all the next
attempts to query that control (other operations have the same
functionality as now).

The existing fixed value of 16 worked for UYVY 720P60 over
2 lanes at 594MHz, or UYVY 1080P60 over 4 lanes. (RGB888
1080P60 needs 6 lanes at 594MHz).
It doesn't allow for lower resolutions to work as the FIFO
underflows.
374 is required for 1080P24 or 1080P30 UYVY over 2 lanes @
972Mbit/s, but >374 means that the FIFO underflows on 1080P50
UYVY over 2 lanes @ 972Mbit/s.
Whilst it would be nice to compute it, the required information
isn't published by Toshiba.

[ Upstream commit 377cc006a364dfdab2f3f221cfad63a9265200b8 ]
When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
to choose a valid format. However that sets the colorspace
based on information read back from the chip, not the colour
format requested.
The result was that if you called try or set format for UYVY
when the current format was RGB3 then you would get told SRGB,
and try RGB3 when current was UYVY and you would get told
SMPTE170M.
The value programmed in the VI_REP register for the colorspace
is always set by this driver, therefore there is no need to read
back the value, and never set to REC709.
Return the colorspace based on the format set/tried instead.

The probe for the TC358743 reads the CHIPID register from
the device and compares it to the expected value of 0.
If the I2C request fails then that also returns 0, so
the driver loads thinking that the device is there.
Generally I2C communications are reliable so there is
limited need to check the return value on every transfer,
therefore only amend the one read during probe to check
for I2C errors.

[ Upstream commit 57b5a302b5d529db96ddc52fbccec005092ebb3d ]
The driver checks if "vq->max_num_buffers + *nbuffers < 3", but
vq->max_num_buffers is (by default) 32, so the check is never true. Nor
does the check make sense.
The original code in the BSP kernel was "vq->num_buffers + *nbuffers <
3", but got mangled along the way to upstream. The intention was to make
sure that at least 3 buffers are allocated.
Fix this by removing the bad lines and setting q->min_reqbufs_allocation
to three.

[ Upstream commit 04caad5a7ba86e830d04750417a15bad8ac2613c ]
With the ATA error model, an NCQ command failure always triggers an abort
(termination) of all NCQ commands queued on the device. In such case, the
SAT or the host must handle the failed command according to the command
sense data and immediately retry all other NCQ commands that were aborted
due to the failed NCQ command.
For SAS HBAs controlled by the mpi3mr driver, NCQ command aborts are not
handled by the HBA SAT and sent back to the host, with an ioc log
information equal to 0x31080000 (IOC_LOGINFO_PREFIX_PL with the PL code
PL_LOGINFO_CODE_SATA_NCQ_FAIL_ALL_CMDS_AFTR_ERR). The function
mpi3mr_process_op_reply_desc() always forces a retry of commands
terminated with the status MPI3_IOCSTATUS_SCSI_IOC_TERMINATED using the
SCSI result DID_SOFT_ERROR, regardless of the ioc_loginfo for the
command. This correctly forces the retry of collateral NCQ abort
commands, but with the retry counter for the command being incremented.
If a command to an ATA device is subject to too many retries due to other
NCQ commands failing (e.g. read commands trying to access unreadable
sectors), the collateral NCQ abort commands may be terminated with an
error as they run out of retries. This violates the SAT specification and
causes hard-to-debug command errors.
Solve this issue by modifying the handling of the
MPI3_IOCSTATUS_SCSI_IOC_TERMINATED status to check if a command is for an
ATA device and if the command ioc_loginfo indicates an NCQ collateral
abort. If that is the case, force the command retry using the SCSI result
DID_IMM_RETRY to avoid incrementing the command retry count.

[ Upstream commit 4051ead99888f101be92c7ce90d2de09aac6fd1c ]
Syzkaller can create many uhid devices that trigger
repeated warnings like:
"hid-generic xxxx: unknown main item tag 0x0"
These messages can flood the system log, especially if a crash occurs
(e.g., with a slow UART console, leading to soft lockups). To mitigate
this, convert `hid_warn()` to use `dev_warn_ratelimited()`.
This helps reduce log noise and improves system stability under fuzzing
or faulty device scenarios.

[ Upstream commit e19bdbaa31082b43dab1d936e20efcebc30aa73d ]
DMA operates in Double Buffer Mode (DBM) when the transfer is cyclic and
there are at least two periods.
When DBM is enabled, the DMA toggles between two memory targets (SxM0AR and
SxM1AR), indicated by the SxSCR.CT bit (Current Target).
There is no need to update the next memory address if two periods are
configured, as SxM0AR and SxM1AR are already properly set up before the
transfer begins in the stm32_dma_start_transfer() function.
This avoids unnecessary updates to SxM0AR/SxM1AR, thereby preventing
potential Transfer Errors. Specifically, when the channel is enabled,
SxM0AR and SxM1AR can only be written if SxSCR.CT=1 and SxSCR.CT=0,
respectively. Otherwise, a Transfer Error interrupt is triggered, and the
stream is automatically disabled.

[ Upstream commit 0370395d45ca6dd53bb931978f0e91ac8dd6f1c5 ]
Probing peripherals in the AON and PERI domains, such as the PVT thermal
sensor and the PWM controller, can lead to boot hangs or unresponsive
devices on the LPi4A board. The root cause is that their parent bus
clocks ('CLK_CPU2AON_X2H' and the 'CLK_PERISYS_APB' clocks) are
automatically gated by the kernel's power-saving mechanisms when the bus
is perceived as idle.
Alternative solutions were investigated, including modeling the parent
bus in the Device Tree with 'simple-pm-bus' or refactoring the clock
driver's parentage. The 'simple-pm-bus' approach is not viable due to
the lack of defined bus address ranges in the hardware manual and its
creation of improper dependencies on the 'pm_runtime' API for consumer
drivers.
Therefore, applying the'`CLK_IGNORE_UNUSED' flag directly to the
essential bus clocks is the most direct and targeted fix. This prevents
the kernel from auto-gating these buses and ensures peripherals remain

This change fixes the boot hang associated with the PVT sensor and
resolves the functional issues with the PWM controller.

Not all tasks have an ABI associated or vDSO mapped,
for example kthreads never do.
If such a task ever ends up calling stack_top(), it will derefence the
NULL ABI pointer and crash.
This can for example happen when using kunit:
mips_stack_top+0x28/0xc0
arch_pick_mmap_layout+0x190/0x220
kunit_vm_mmap_init+0xf8/0x138

usercopy_test_init+0xb8/0x240
kunit_try_run_case+0x5c/0x1a8
kunit_generic_run_threadfn_adapter+0x28/0x50
kthread+0x118/0x240
ret_from_kernel_thread+0x14/0x1c
Only dereference the ABI point if it is set.
The GIC page is also included as it is specific to the vDSO.
Also move the randomization adjustment into the same conditional.

[ Upstream commit 99f2211a9d89fe34b3fa847fd7a4475171406cd0 ]
probe() requests the reset GPIO to be set to high when getting it.
Immeditately after this hi556_resume() is called and sets the GPIO low.
If the GPIO was low before requesting it this will result in the GPIO
only very briefly spiking high and the sensor not being properly reset.
The same problem also happens on back to back runtime suspend + resume.
Fix this by adding a sleep of 2 ms in hi556_resume() before setting
the GPIO low (if there is a reset GPIO).
The final sleep is kept unconditional, because if there is e.g. no reset
GPIO but a controllable clock then the sensor also needs some time after
enabling the clock.

When the bfad_im_probe() function fails during initialization, the memory
pointed to by bfad->im is freed without setting bfad->im to NULL.
Subsequently, during driver uninstallation, when the state machine enters

it attempts to free the memory pointed to by bfad->im again, thereby
triggering a double-free vulnerability.

[ Upstream commit 40efc43eb7ffb5a4e2f998c13b8cfb555e671b92 ]
The driver probes with the invalid timeout value when
'iTCO_wdt_set_timeout()' fails, as its return value is not checked. In
this case, when executing "wdctl", we may get:
Device: /dev/watchdog0
Timeout: 30 seconds
Timeleft: 613 seconds
The timeout value is the value of "heartbeat" or "WATCHDOG_TIMEOUT", and
the timeleft value is calculated from the register value we actually read
(0xffff) by masking with 0x3ff and converting ticks to seconds (* 6 / 10).
Add error handling to return the failure code if 'iTCO_wdt_set_timeout()'
fails, ensuring the driver probe fails and prevents invalid operation.

sprintf() is discouraged for use with bounded destination buffers
as it does not prevent buffer overflows when the formatted output
exceeds the destination buffer size. snprintf() is a safer
alternative as it limits the number of bytes written and ensures
NUL-termination.
Replace sprintf() with snprintf() for copying the debug string
into a temporary buffer, using ORANGEFS_MAX_DEBUG_STRING_LEN as
the maximum size to ensure safe formatting and prevent memory
corruption in edge cases.
EDIT: After this patch sat on linux-next for a few days, Dan
Carpenter saw it and suggested that I use scnprintf instead of
snprintf. I made the change and retested.

[ Upstream commit 88828c7e940dd45d139ad4a39d702b23840a37c5 ]
On newer boards featuring the A523 SoC, the AXP323 (related to the
AXP313) is paired with the AXP717 and serves as a secondary PMIC
providing additional regulator outputs. However the MFD cells are all
registered with PLATFORM_DEVID_NONE, which causes the regulator cells
to conflict with each other.
Commit e37ec3218870 ("mfd: axp20x: Allow multiple regulators") attempted
to fix this by switching to PLATFORM_DEVID_AUTO so that the device names
would all be different, however that broke IIO channel mapping, which is
also tied to the device names. As a result the change was later reverted.
Instead, here we attempt to make sure the AXP313/AXP323 regulator cell
does not conflict by explicitly giving it an ID number. This was
previously done for the AXP809+AXP806 pair used with the A80 SoC.
