commit fbffb8c7c7bb4d38e9f65e0bee446685011de5d8 upstream.
When __auxiliary_device_add() fails, reset_add_gpio_aux_device()
calls auxiliary_device_uninit(adev).
The device release callback reset_gpio_aux_device_release() frees
adev, but the current error path then calls kfree(adev) again,
causing a double free.
Keep kfree(adev) for the auxiliary_device_init() failure path, but
avoid freeing adev after auxiliary_device_uninit().

commit 57ad0d4a00f5d3e80f33ba2da8d560c73d83dc22 upstream.
commit fcc43a7e294f ("s390/configs: Set HZ=1000") changed the interrupt
frequency of the system. On machines with heavy load and many perf event
overflows, this might lead to an exception. Dmesg displays these entries:
[112.242542] cpum_sf: Loading sampling controls failed: op 1 err -22
One line per CPU online.
The root cause is the CPU Measurement sampling facility overflow
adjustment. Whenever an overflow (too much samples per tick) occurs, the
sampling rate is adjusted and increased. This was done without observing
the maximum sampling rate limit. When the current sampling interval is
higher than the maximum sampling rate limit, the lsctl instruction raises
an exception. The error messages is the result of such an exception.
Observe the upper limit when the new sampling rate is recalculated.

commit c8d46f17c2fc7d25c18e60c008928aecab26184d upstream.
Tests showed that there is a memory leak if CCA cards are used as
accelerator for clear key RSA requests (ME and CRT). With the last
rework for the memory allocation the AP messages are allocated by
ap_init_apmsg() but for some reason on two places (ME and CRT) the
older allocation was still in place. So the first allocation simple
was never freed.

commit 59e1be1278f064d7172b00473b7e0c453cb1ec52 upstream.
cqspi_exec_mem_op() increments the runtime PM usage counter before all
refcount checks are performed. If one of these checks fails, the function
returns without dropping the PM reference.
Move the pm_runtime_resume_and_get() call after the refcount checks so
that runtime PM is only acquired when the operation can proceed and
drop the inflight_ops refcount if the PM resume fails.

commit c7596f9001e2b83293e3658e4e1addde69bb335d upstream.
There's no point letting the driver probe if there is no flash, as
trying to do a firmware upload will fail. Move the code that attempts
to get the flash from firmware upload to probe, and let it emit a
message to users stating why auto-update is not supported.
The code currently could have a problem if there's a flash in
devicetree, but the system controller driver fails to get a pointer to
it from the mtd subsystem, which will cause
mpfs_sys_controller_get_flash() to return an error. Check for errors and
null, instead of just null, in the new clause.

commit 3fb43a7a5b44713f892c58ead2e5f3a1bc9f4ee7 upstream.
`me4000_xilinx_download()` loads the firmware that was requested by
`request_firmware()`. It is possible for it to overrun the source
buffer because it blindly trusts the file format. It reads a data
stream length from the first 4 bytes into variable `file_length` and
reads the data stream contents of length `file_length` from offset 16
onwards.
Add a test to ensure that the supplied firmware is long enough to
contain the header and the data stream. On failure, log an error and
return `-EINVAL`.
Note: The firmware loading was totally broken before commit ac584af59945
("staging: comedi: me4000: fix firmware downloading"), but that is the
most sensible target for this fix.

commit 101ab946b79ad83b36d5cfd47de587492a80acf0 upstream.
If the driver's COMEDI "attach" handler function (`atmio16d_attach()`)
returns an error, the COMEDI core will call the driver's "detach"
handler function (`atmio16d_detach()`) to clean up. This calls
`reset_atmio16d()` unconditionally, but depending on where the error
occurred in the attach handler, the device may not have been
sufficiently initialized to call `reset_atmio16d()`. It uses
`dev->iobase` as the I/O port base address and `dev->private` as the
pointer to the COMEDI device's private data structure. `dev->iobase`
may still be set to its initial value of 0, which would result in
undesired writes to low I/O port addresses. `dev->private` may still be
`NULL`, which would result in null pointer dereferences.
Fix `atmio16d_detach()` by checking that `dev->private` is valid
(non-null) before calling `reset_atmio16d()`. This implies that
`dev->iobase` was set correctly since that is set up before
`dev->private`.

commit 4b9a9a6d71e3e252032f959fb3895a33acb5865c upstream.
`struct comedi_device` is the main controlling structure for a COMEDI
device created by the COMEDI subsystem. It contains a member `spinlock`
containing a spin-lock that is initialized by the COMEDI subsystem, but
is reserved for use by a low-level driver attached to the COMEDI device
(at least since commit 25436dc9d84f ("Staging: comedi: remove RT
code")).
Some COMEDI devices (those created on initialization of the COMEDI
subsystem when the "comedi.comedi_num_legacy_minors" parameter is
non-zero) can be attached to different low-level drivers over their
lifetime using the `COMEDI_DEVCONFIG` ioctl command. This can result in
inconsistent lock states being reported when there is a mismatch in the
spin-lock locking levels used by each low-level driver to which the
COMEDI device has been attached. Fix it by reinitializing
`dev->spinlock` before calling the low-level driver's `attach` function
pointer if `CONFIG_LOCKDEP` is enabled.

commit 29f644f14b89e6c4965e3c89251929e451190a66 upstream.
syzbot reported a memory leak [1], because commit 4e1da516debb ("comedi:
Add reference counting for Comedi command handling") did not consider
the exceptional exit case in do_cmd_ioctl() where runflags is not set.
This caused chanlist not to be properly freed by do_become_nonbusy(),
as it only frees chanlist when runflags is correctly set.
Added a check in do_become_nonbusy() for the case where runflags is not
set, to properly free the chanlist memory.

commit 93853512f565e625df2397f0d8050d6aafd7c3ad upstream.
The dt2815 driver crashes when attached to I/O ports without actual
hardware present. This occurs because syzkaller or users can attach
the driver to arbitrary I/O addresses via COMEDI_DEVCONFIG ioctl.
When no hardware exists at the specified port, inb() operations return
0xff (floating bus), but outb() operations can trigger page faults due
to undefined behavior, especially under race conditions:
BUG: unable to handle page fault for address: 000000007fffff90
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page
RIP: 0010:dt2815_attach+0x6e0/0x1110
Add hardware detection by reading the status register before attempting
any write operations. If the read returns 0xff, assume no hardware is
present and fail the attach with -ENODEV. This prevents crashes from
outb() operations on non-existent hardware.

commit f97e96c303d689708f7f713d8f3afcc31f1237e9 upstream.
This device has a union descriptor that is just garbage
and needs a custom descriptor.
In principle this could be done with a (conditionally
activated) heuristic. That would match more devices
without a need for defining a new quirk. However,
this always carries the risk that the heuristics
does the wrong thing and leads to more breakage.
Defining the quirk and telling it exactly what to do
is the safe and conservative approach.

commit 7f138de156b20d9f9da6f72f90b63c01941d97d3 upstream.
linedisp_release() currently retrieves the enclosing struct linedisp via
to_linedisp(). That lookup depends on the attachment list, but the
attachment may already have been removed before put_device() invokes the
release callback. This can happen in linedisp_unregister(), and can also
be reached from some linedisp_register() error paths.
In that case, to_linedisp() returns NULL and linedisp_release()
dereferences it while freeing the display resources.
The struct device released here is the embedded linedisp->dev used by
linedisp_register(), so retrieve the enclosing object directly with
container_of() instead.

Commit 61a11cf4812726aceaee17c96432e1c08f6ed6cb upstream.
Commit 96189080265e addressed one case of ctx->rings being potentially
accessed while a resize is happening on the ring, but there are still
a few others that need handling. Add a helper for retrieving the
rings associated with an io_uring context, and add some sanity checking
to that to catch bad uses. ->rings_rcu is always valid, as long as it's
used within RCU read lock. Any use of ->rings_rcu or ->rings inside
either ->uring_lock or ->completion_lock is sane as well.
Do the minimum fix for the current kernel, but set it up such that this
basic infra can be extended for later kernels to make this harder to
mess up in the future.

commit c32f8748d70c8fc77676ad92ed76cede17bf2c48 upstream.
When cdns3_gadget_start() fails, the DRD hardware is left in gadget mode
while software state remains INACTIVE, creating hardware/software state
inconsistency.
When switching to host mode via sysfs:
echo host > /sys/class/usb_role/13180000.usb-role-switch/role
The role state is not set to CDNS_ROLE_STATE_ACTIVE due to the error,
so cdns_role_stop() skips cleanup because state is still INACTIVE.
This violates the DRD controller design specification (Figure22),
which requires returning to idle state before switching roles.
This leads to a synchronous external abort in xhci_gen_setup() when
setting up the host controller:

This prevents potential crashes when ep_queue is called on endpoints

commit 0179c6da0793ae03607002c284b53b6d584172d0 upstream.
Commit 53a2d95df836 ("usb: core: add phy notify connect and disconnect")
causes double use of the 'usb3-phy' in certain cases.
Since that commit, if a generic PHY named 'usb3-phy' is specified in
the device tree, that is getting added to the 'phy_roothub' list of the
secondary HCD by the usb_phy_roothub_alloc_usb3_phy() function. However,
that PHY is getting added also to the primary HCD's 'phy_roothub' list
by usb_phy_roothub_alloc() if there is no generic PHY specified with
'usb2-phy' name.
This causes that the usb_add_hcd() function executes each phy operations
twice on the 'usb3-phy'. Once when the primary HCD is added, then once
again when the secondary HCD is added.
The issue affects the Marvell Armada 3700 platform at least, where a
custom name is used for the USB2 PHY:
$ git grep 'phy-names.*usb3' arch/arm64/boot/dts/marvell/armada-37xx.dtsi | tr '\t' ' '
arch/arm64/boot/dts/marvell/armada-37xx.dtsi: phy-names = "usb3-phy", "usb2-utmi-otg-phy";
Extend the usb_phy_roothub_alloc_usb3_phy() function to skip adding the
'usb3-phy' to the 'phy_roothub' list of the secondary HCD when 'usb2-phy'
is not specified in the device tree to avoid the double use.

commit 9bb4b5ed7f8c4f95cc556bdf042b0ba2fa13557a upstream.
dwc2_gadget_exit_clock_gating() internally calls call_gadget() macro,
which expects hsotg->lock to be held since it does spin_unlock/spin_lock
around the gadget driver callback invocation.
However, dwc2_hsotg_udc_stop() calls dwc2_gadget_exit_clock_gating()
without holding the lock. This leads to:
- spin_unlock on a lock that is not held (undefined behavior)
- The lock remaining held after dwc2_gadget_exit_clock_gating() returns,
causing a deadlock when spin_lock_irqsave() is called later in the
same function.
Fix this by acquiring hsotg->lock before calling
dwc2_gadget_exit_clock_gating() and releasing it afterwards, which
satisfies the locking requirement of the call_gadget() macro.

The responsibility of manipulating offload_usage now lies entirely with

commit 01af542392b5d41fd659d487015a71f627accce3 upstream.
When device_register() fails, ulpi_register() calls put_device() on
ulpi->dev.
The device release callback ulpi_dev_release() drops the OF node
reference and frees ulpi, but the current error path in
ulpi_register_interface() then calls kfree(ulpi) again, causing a
double free.
Let put_device() handle the cleanup through ulpi_dev_release() and
avoid freeing ulpi again in ulpi_register_interface().

commit 8c27b1bce059a11a8d3c8682984e13866f0714af upstream.
After commit 2cedb296988c ("mei: me: trigger link reset if hw ready is unexpected")
some devices started to show long resume times (5-7 seconds).
This happens as mei falsely detects unready hardware,
starts parallel link reset flow and triggers link reset timeouts
in the resume callback.
Address it by performing detection of unready hardware only
when driver is in the MEI_DEV_ENABLED state instead of blacklisting
states as done in the original patch.
This eliminates active waitqueue check as in MEI_DEV_ENABLED state
there will be no active waitqueue.

commit 679c04c10d65d32a3f269e696b22912ff0a001b9 upstream.
The st_lsm6dsx_hwfifo_odr_store() function, which is called when userspace
writes the buffer sampling frequency sysfs attribute, calls
st_lsm6dsx_check_odr(), which accesses the odr_table array at index
`sensor->id`; since this array is only 2 entries long, an access for any
sensor type other than accelerometer or gyroscope is an out-of-bounds
access.
The motivation for being able to set a buffer frequency different from the
sensor sampling frequency is to support use cases that need accurate event
detection (which requires a high sampling frequency) while retrieving
sensor data at low frequency. Since all the supported event types are
generated from acceleration data only, do not create the buffer sampling
frequency attribute for sensor types other than the accelerometer.

commit 630748afa7030b272b7bee5df857e7bcf132ed51 upstream.
The st_lsm6dsx_set_fifo_odr() function, which is called when enabling and
disabling the hardware FIFO, checks the contents of the hw->settings->batch
array at index sensor->id, and then sets the current ODR value in sensor
registers that depend on whether the register address is set in the above
array element. This logic is valid for internal sensors only, i.e. the
accelerometer and gyroscope; however, since commit c91c1c844ebd ("iio: imu:
st_lsm6dsx: add i2c embedded controller support"), this function is called
also when configuring the hardware FIFO for external sensors (i.e. sensors
accessed through the sensor hub functionality), which can result in
unrelated device registers being written.
Add a check to the beginning of st_lsm6dsx_set_fifo_odr() so that it does
not touch any registers unless it is called for internal sensors.

commit fdc7aa54a5d44c05880a4aad7cfb41aacfd16d7b upstream.
Rework vcnl4035_trigger_consumer_handler() so that we are not passing
what should be a u16 value as an int * to regmap_read(). This won't
work on bit endian systems.
Instead, add a new unsigned int variable to pass to regmap_read(). Then
copy that value into the buffer struct.
The buffer array is replaced with a struct since there is only one value
being read. This allows us to use the correct u16 data type and has a
side-effect of simplifying the alignment specification.
Also fix the endianness of the scan format from little-endian to CPU
endianness. Since we are using regmap to read the value, it will be
CPU-endian.

commit 86133fb1ec36b2f5cec29d71fbae84877c3a1358 upstream.
The switch statement in ade9000_write_raw() attempts to match
chan->address against ADE9000_REG_AWATTOS (0x00F) to dispatch
the calibration offset write for active power channels. However,
chan->address is set via ADE9000_ADDR_ADJUST(ADE9000_REG_AWATT,
num), so after masking the phase bits, tmp holds
ADE9000_REG_AWATT (0x210), which never matches 0x00F.
As a result, writing IIO_CHAN_INFO_CALIBBIAS for IIO_POWER always
falls through to the default case and returns -EINVAL, making
active power offset calibration silently broken.
Fix this by matching against ADE9000_REG_AWATT instead, which is
the actual base address stored in chan->address for watt channels.
Reference:ADE9000 datasheet (Rev. B), AWATTOS is the offset correction
register at 0x00F (p. 44), while AWATT is the total active power
register at 0x210 (p. 48).

resulting in ti_ads7950_get() only returning 0 as GPIO state (or error).
Fix this by introducing a separate variable to hold the state.

commit e2fa075d5ce1963e7cb7b0ac708ba567e5af66db upstream.
The GPIO get callback is expected to return 0 or 1 (or a negative error
code). Ensure that the value returned by ti_ads7950_get() for output
pins is normalized to the [0, 1] range.
Fixes: 86ef402d805d ("gpiolib: sanitize the return value of gpio_chip::get()")

commit e2b0ae529db4766584e77647cefe3ec15c3d842e upstream.
Add device IDs for the Razer Wolverine V3 Pro controller in both
wired (0x0a57) and wireless 2.4 GHz dongle (0x0a59) modes.
The controller uses the Xbox 360 protocol (vendor-specific class,
subclass 93, protocol 1) on interface 0 with an identical 20-byte
input report layout, so no additional processing is needed.
