The datasheet specifies, that the IRQ_B pin is pulled low when any
unmasked interrupt bit status is changed, and it is released high once
the application processor reads the INT1 register. As it specifies a
level-low behavior, it should not force a falling-edge interrupt.
Remove the IRQF_TRIGGER_FALLING to not force the falling-edge interrupt
and instead rely on the flag from the device tree.

So far the driver populated the struct can_priv::do_set_bittiming() and
struct can_priv::fd::do_set_data_bittiming() callbacks.
Before bringing up the interface, user space has to configure the bitrates.
With these callbacks the configuration is directly forwarded into the CAN
hardware. Then the interface can be brought up.
An ifdown-ifup cycle (without changing the bit rates) doesn't re-configure
the bitrates in the CAN hardware. This leads to a problem with the
CANable-2.5 [1] firmware, which resets the configured bit rates during
ifdown.
To fix the problem remove both bit timing callbacks and always configure
the bitrates in the struct net_device_ops::ndo_open() callback.

If a broken ucan device gets a message with the message length field set
to 0, then the driver will loop for forever in
ucan_read_bulk_callback(), hanging the system. If the length is 0, just

This has been fixed in the kvaser_usb driver in the past in commit

When looking at the data in a USB urb, the actual_length is the size of
the buffer passed to the driver, not the transfer_buffer_length which is
set by the driver as the max size of the buffer.
When parsing the messages in ems_usb_read_bulk_callback() properly check
the size both at the beginning of parsing the message to make sure it is
big enough for the expected structure, and at the end of the message to
make sure we don't overflow past the end of the buffer for the next
message.

esd_usb_probe() constructs bulk pipes for two endpoints without
verifying their transfer types:
- usb_rcvbulkpipe(dev->udev, 1) for RX (version reply, async RX data)
- usb_sndbulkpipe(dev->udev, 2) for TX (version query, CAN frames)
A malformed USB device can present these endpoints with transfer types
that differ from what the driver assumes, triggering the WARNING in
usb_submit_urb().
Use usb_find_common_endpoints() to discover and validate the first
bulk IN and bulk OUT endpoints at probe time, before any allocation.
Found pipes are saved to struct esd_usb and code uses them directly
instead of making pipes in place.

The mcp251x_open() function call free_irq() in its error path with the
mpc_lock mutex held. But if an interrupt already occurred the
interrupt handler will be waiting for the mpc_lock and free_irq() will
deadlock waiting for the handler to finish.
This issue is similar to the one fixed in commit 7dd9c26bd6cf ("can:
mcp251x: fix deadlock if an interrupt occurs during mcp251x_open") but
for the error path.
To solve this issue move the call to free_irq() after the lock is
released. Setting `priv->force_quit = 1` beforehand ensure that the IRQ
handler will exit right away once it acquired the lock.

In mt6363_regulator_probe(), devm_add_action_or_reset() is used to
automatically dispose of the IRQ mapping if the probe fails or the
device is removed.
The manual call to irq_dispose_mapping() in the error path was redundant
as the reset action already triggers mt6363_irq_remove(). Furthermore,

Recent changes linux mainline resulted in warning:
"genirq: Warn about using IRQF_ONESHOT without a threaded handler"
when HID sensor hub is used.
When INDIO_BUFFER_TRIGGERED is used, the core attaches a poll function
when enabling the buffer. This poll function uses request_threaded_irq()
with both bottom half and top half handlers. But when using HID
sensor hub, bottom half (thread handler) is not registered.
In HID sensors, once a sensor is powered on, the hub collects samples
and pushes data to the host when programmed thresholds are met. When
this data is received for a sensor, it is pushed using
iio_push_to_buffers_with_ts().
The sensor is powered ON or OFF based on the trigger callback
set_trigger_state() when the poll function is attached. During the call
to iio_triggered_buffer_setup_ext(), the HID sensor specifies only a
handler function but provides no thread handler, as there is no data
to read from the hub in thread context. Internally, this results in
calling request_threaded_irq(). Recent kernel changes now warn when
request_threaded_irq() is called without a thread handler.
To address this issue, fundamental changes are required to avoid using
iio_triggered_buffer_setup_ext(). HID sensors can use
INDIO_BUFFER_SOFTWARE instead of INDIO_BUFFER_TRIGGERED, as this can
work in trigger-less mode.
In this approach, when user space opens the buffer, the sensor is powered
on, and when the buffer is closed, the sensor is powered off using
iio_buffer_setup_ops callbacks.

In ad4062_request_irq(), when request irq for "gp1", the code uses
IRQF_ONESHOT flag, which is not appropriate for a primary handler
that does not have a secondary threaded handler.
And since commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT
without a threaded handler"), the IRQ core checks IRQF_ONESHOT flag
in IRQ request and gives a warning if there is no threaded handler.
Since there is no threaded handler, replace devm_request_threaded_irq
with devm_request_irq, and replace IRQF_ONESHOT with IRQF_NO_THREAD.
Also remove an extraneous semicolon at the end of

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.

accelerometer and gyroscope; however, since commit c91c1c844ebd ("iio: imu:

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.

not touch any registers unless it is called for internal sensors.

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).

ds1119_single_conversion()
In ads1119_single_conversion(), if pm_runtime_resume_and_get() fails,
the code jumps to the pdown label, which calls
pm_runtime_put_autosuspend().
Since pm_runtime_resume_and_get() automatically decrements the usage
counter on failure, the subsequent call to pm_runtime_put_autosuspend()
causes an unbalanced reference counter.

In flush_write_buffer, &p->frag_sem is acquired and then the loaded store
function is called, which, here, is target_core_item_dbroot_store(). This
function called filp_open(), following which these functions were called
(in reverse order), according to the call trace:
down_read
__configfs_open_file
do_dentry_open
vfs_open
do_open
path_openat
do_filp_open
file_open_name
filp_open
target_core_item_dbroot_store
flush_write_buffer
configfs_write_iter
target_core_item_dbroot_store() tries to validate the new file path by
trying to open the file path provided to it; however, in this case, the bug
report shows:
db_root: not a directory: /sys/kernel/config/target/dbroot
indicating that the same configfs file was tried to be opened, on which it
is currently working on. Thus, it is trying to acquire frag_sem semaphore
of the same file of which it already holds the semaphore obtained in
flush_write_buffer(), leading to acquiring the semaphore in a nested manner
and a possibility of recursive locking.
Fix this by modifying target_core_item_dbroot_store() to use kern_path()
instead of filp_open() to avoid opening the file using filesystem-specific
function __configfs_open_file(), and further modifying it to make this fix
compatible.

The Iomega ZIP 100 (Z100P2) can't process IO Advice Hints Grouping mode
page query. It immediately switches to the status phase 0xb8 after
receiving the subpage code 0x05 of MODE_SENSE_10 command, which fails
imm_out() and turns into DID_ERROR of this command, which leads to unusable
device. This was tested with an Iomega ZIP 100 (Z100P2) connected with a
StarTech PEX1P2 AX99100 PCIe parallel port card.
Prior to this fix, Test Unit Ready fails and the drive can't be used:

The driver retains reset history even after the IOC has successfully
reached the READY state. That leaves stale reset information active during
normal operation and can mislead recovery and diagnostics. In addition, if
the IOC becomes READY just as the ready timeout loop exits, the driver
still follows the failure path and may retry or report failure incorrectly.
Clear reset history once READY is confirmed so driver state matches actual
IOC status. After the timeout loop, recheck the IOC state and treat READY
as success instead of failing.

Extend the MAC_TCR_SS (Speed Select) register field width from 2 bits
to 3 bits to properly support all speed settings.
The MAC_TCR register's SS field encoding requires 3 bits to represent
all supported speeds:
- 0x00: 10Gbps (XGMII)
- 0x02: 2.5Gbps (GMII) / 100Mbps
- 0x03: 1Gbps / 10Mbps
- 0x06: 2.5Gbps (XGMII) - P100a only
With only 2 bits, values 0x04-0x07 cannot be represented, which breaks
2.5G XGMII mode on newer platforms and causes incorrect speed select
values to be programmed.

speed is not 1G
When both eth interfaces with links up are added to a bridge or hsr
interface, ping fails if the link speed is not 1Gbps (e.g., 100Mbps).
The issue is seen because when switching to offload (bridge/hsr) mode,
prueth_emac_restart() restarts the firmware and clears DRAM with
memset_io(), setting all memory to 0. This includes PORT_LINK_SPEED_OFFSET
which firmware reads for link speed. The value 0 corresponds to
FW_LINK_SPEED_1G (0x00), so for 1Gbps links the default value is correct
and ping works. For 100Mbps links, the firmware needs FW_LINK_SPEED_100M
(0x01) but gets 0 instead, causing ping to fail. The function
emac_adjust_link() is called to reconfigure, but it detects no state change
(emac->link is still 1, speed/duplex match PHY) so new_state remains false
and icssg_config_set_speed() is never called to correct the firmware speed
value.
The fix resets emac->link to 0 before calling emac_adjust_link() in
prueth_emac_common_start(). This forces new_state=true, ensuring
icssg_config_set_speed() is called to write the correct speed value to
firmware memory.

Commit 31a7a0bbeb00 ("dpaa2-switch: add bounds check for if_id in IRQ

access. If an out-of-bounds if_id is detected, the interrupt status is
not cleared. This may result in an interrupt storm.
Clear the interrupt status after detecting an out-of-bounds if_id to avoid
the problem.

KVM/arm64 fixes for 7.0, take #1
- Make sure we don't leak any S1POE state from guest to guest when
the feature is supported on the HW, but not enabled on the host
- Propagate the ID registers from the host into non-protected VMs
managed by pKVM, ensuring that the guest sees the intended feature set
- Drop double kern_hyp_va() from unpin_host_sve_state(), which could
bite us if we were to change kern_hyp_va() to not being idempotent
- Don't leak stage-2 mappings in protected mode
- Correctly align the faulting address when dealing with single page
stage-2 mappings for PAGE_SIZE > 4kB
- Fix detection of virtualisation-capable GICv5 IRS, due to the
maintainer being obviously fat fingered...
- Remove duplication of code retrieving the ASID for the purpose of
S1 PT handling
- Fix slightly abusive const-ification in vgic_set_kvm_info()
