cifs: do not disable interface polling on failure
When a server has multichannel enabled, we keep polling the server
for interfaces periodically. However, when this query fails, we
disable the polling. This can be problematic as it takes away the
chance for the server to start advertizing again.
This change reschedules the delayed work, even if the current call
failed. That way, multichannel sessions can recover.

cifs: serialize other channels when query server interfaces is pending
Today, during smb2_reconnect, session_mutex is released as soon as
the tcon is reconnected and is in a good state. However, in case
multichannel is enabled, there is also a query of server interfaces that
follows. We've seen that this query can race with reconnects of other
channels, causing them to step on each other with reconnects.
This change extends the hold of session_mutex till after the query of
server interfaces is complete. In order to avoid recursive smb2_reconnect
checks during query ioctl, this change also introduces a session flag
for sessions where such a query is in progress.

cifs: deal with the channel loading lag while picking channels
Our current approach to select a channel for sending requests is this:
1. iterate all channels to find the min and max queue depth
2. if min and max are not the same, pick the channel with min depth
3. if min and max are same, round robin, as all channels are equally loaded
The problem with this approach is that there's a lag between selecting
a channel and sending the request (that increases the queue depth on the channel).
While these numbers will eventually catch up, there could be a skew in the
channel usage, depending on the application's I/O parallelism and the server's
speed of handling requests.
With sufficient parallelism, this lag can artificially increase the queue depth,
thereby impacting the performance negatively.
This change will change the step 1 above to start the iteration from the last
selected channel. This is to reduce the skew in channel usage even in the presence
of this lag.

the mod->modname field and crash via UAF.
Fix this by still freeing the mod_maps that are attached to kallsyms

- Do not bother allocating mod_maps for kallsyms if ftrace_disable is
set

creates the code and data structures needed for that trace event.

When the dax_fault_actor() helper was factored out, it removed the calls
to the dax_pmd_insert_mapping and dax_insert_mapping events but never
removed the events themselves. As each event created takes up memory
(roughly 5K each), this is a waste as it is never used.
Remove the unused dax_pmd_insert_mapping and dax_insert_mapping trace

Pull LED updates from Lee Jones:
"LED Triggers:
- Allow writing "default" to the sysfs 'trigger' attribute to set an
LED to its default trigger
- If the default trigger is "none", writing "default" will remove the
current trigger
- Updated sysfs ABI documentation for the new "default" trigger
functionality
LED KUnit Testing:
- Provide a skeleton KUnit test suite for the LEDs framework
- Expand the LED class device registration KUnit test to cover more
scenarios, including 'brightness_get' behavior
- Add KUnit tests for the LED lookup and get API ('led_add_lookup',
'devm_led_get')
LED Flash Class:
- Add support for setting flash/strobe duration through a new
'duration_set' op and 'led_set_flash_duration()' function, aligning
with 'V4L2_CID_FLASH_DURATION'
Texas Instruments TPS6131x:
- Add a new driver for the TPS61310/TPS61311 flash LED controllers
- The driver supports the device's three constant-current sinks for
flash and torch modes
LED Core:
- Prevent potential 'snprintf()' truncations in LED names by checking
for buffer overflows
ChromeOS EC LEDs:
- Avoid a -Wflex-array-member-not-at-end GCC warning by replacing an
on-stack flexible structure definition with a utility function call
Multicolor LEDs:
- Fix issue where setting multi_intensity while software blinking is
active could stop blinking
PCA955x LEDs:
- Avoid potential buffer overflow when creating default labels by
changing a field's type to 'u8' and updating format specifiers
PCA995x LEDs:
- Fix a typo (stray space) in an 'of_device_id' entry in the
'pca995x_of_match' table
Kconfig:
- Prevent LED drivers from being enabled by default when
'COMPILE_TEST' is set
Device Property API:
- Split 'device_get_child_node_count()' into a new helper
'fwnode_get_child_node_count()' that doesn't require a device
struct, making the API more symmetrical
Driver Modernization (using 'fwnode_get_child_node_count()'):
- Update 'leds-pwm-multicolor', 'leds-ncp5623' and 'leds-ncp5623' to
use the new 'fwnode_get_child_node_count()' helper, removing their
custom implementation
- As above in the USB Type-C TCPM driver
Driver Modernization (using new GPIO setter callbacks):
- Convert 'leds-lgm-sso' to use new GPIO line value setter callbacks
which return an integer for error handling
- Convert 'leds-pca955x', 'leds-pca9532' and 'leds-tca6507' to use
new GPIO setter callbacks
Documentation:
- Remove the '.rst' extension for 'leds-st1202' in the documentation
index for consistency
LP8860 LEDs:
- Use 'regmap_multi_reg_write()' for EEPROM writes instead of manual
looping
- Use scoped mutex guards and 'devm_mutex_init()' to simplify
function exits and ensure automatic cleanup
- Remove default register definitions that are unused when regmap
caching is not active
- Use 'devm_regulator_get_enable_optional()' to handle the optional
regulator, simplifying enabling and removing manual disabling
- Refactor 'lp8860_unlock_eeprom()' to only perform the unlock
operation, removing the lock part and an unnecessary parameter
- Use a 'devm' action to disable the enable-GPIO, simplifying cleanup
and error paths, and remove the now-empty '.remove()' function
Turris Omnia LEDs:
- Drop unnecessary commas in terminator entries of 'struct attribute'
and 'struct of_device_id' arrays
MT6370 RGB LEDs:
- Use the 'LINEAR_RANGE()' for defining 'struct linear_range' entries
to improve robustness
Texas Instruments TPS6131x:
- Add new devicetree bindings for the TI TPS61310/TPS61311 flash LED
driver"

dm-stripe: small code cleanup
This commit doesn't fix any bug, it is just code cleanup. Use the
function format_dev_t instead of sprintf, because format_dev_t does the
same thing.
Remove the useless memset call.
An unsigned integer can take at most 10 digits, so extend the array size
to 22. (note that because the range of minor and major numbers is limited,
the size 16 could not be exceeded, thus this function couldn't write
beyond string end)

dm-mirror: fix a tiny race condition
There's a tiny race condition in dm-mirror. The functions queue_bio and
write_callback grab a spinlock, add a bio to the list, drop the spinlock
and wake up the mirrord thread that processes bios in the list.
It may be possible that the mirrord thread processes the bio just after
spin_unlock_irqrestore is called, before wakeup_mirrord. This spurious
wake-up is normally harmless, however if the device mapper device is
unloaded just after the bio was processed, it may be possible that
wakeup_mirrord(ms) uses invalid "ms" pointer.
Fix this bug by moving wakeup_mirrord inside the spinlock.

forever: the "master" device was not always present depending on a

absence of a Kconfig symbol to force its presence. This was a problem
for runtime PM operations which might not have the "master" device
available in all situation.
The SPI NAND subsystem has seen the introduction of DTR operations
(the equivalent of DDR transfers), which involved quite a few
preparation patches for clarifying macro names.
In the raw NAND subsystem, the brcmnand driver has been "fixed" for
old legacy SoCs with an update of the ->exec_op() hook, there has been
the introduction of a new controller driver named Loongson-1, and the
Qualcomm driver has received quite a few misc fixes as well as a new

strscpy(module_name, mod_map->mod->name, MODULE_NAME_LEN);
...
The problem is when a module triggers an issue with ftrace and
sets ftrace_disable. The ftrace_disable is set when an anomaly is
discovered and to prevent any more damage, ftrace stops all text
modification. The issue that happened was that the ftrace_disable stops
more than just the text modification.
When a module is loaded, its init functions can also be traced. Because
kallsyms deletes the init functions after a module has loaded, ftrace
saves them when the module is loaded and function tracing is enabled. This
allows the output of the function trace to show the init function names
instead of just their raw memory addresses.
When a module is removed, ftrace_release_mod() is called, and if
ftrace_disable is set, it just returns without doing anything more. The
problem here is that it leaves the mod_list still around and if kallsyms
is called, it will call into this code and access the module memory that
has already been freed as it will return:
strscpy(module_name, mod_map->mod->name, MODULE_NAME_LEN);
Where the "mod" no longer exists and triggers a UAF bug.

- Make the irqbypass hooks resilient to changes in the GSI<->MSI
routing, avoiding behind stale vLPI mappings being left behind. The
fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
and nuking the vLPI mapping upon a routing change.
- Close another VGIC race where vCPU creation races with VGIC
creation, leading to in-flight vCPUs entering the kernel w/o private
IRQs allocated.
- Fix a build issue triggered by the recently added workaround for
Ampere's AC04_CPU_23 erratum.
- Correctly sign-extend the VA when emulating a TLBI instruction
potentially targeting a VNCR mapping.
- Avoid dereferencing a NULL pointer in the VGIC debug code, which can
happen if the device doesn't have any mapping yet.

rtmutex_api: provide correct extern functions
Commit
fb49f07ba1d9 ("locking/mutex: implement mutex_lock_killable_nest_lock")
changed the set of functions that mutex.c defines when CONFIG_DEBUG_LOCK_ALLOC
is set.
- it removed the "extern" declaration of mutex_lock_killable_nested from
include/linux/mutex.h, and replaced it with a macro since it could be
treated as a special case of _mutex_lock_killable. It also removed a
definition of the function in kernel/locking/mutex.c.
- likewise, it replaced mutex_trylock() with the more generic
mutex_trylock_nest_lock() and replaced mutex_trylock() with a macro.
However, it left the old definitions in place in kernel/locking/rtmutex_api.c,
which causes failures when building with CONFIG_RT_MUTEXES=y. Bring over
the changes.

watchdog: iTCO_wdt: Update the heartbeat value after clamping timeout
When executing "modprobe iTCO_wdt heartbeat=700", the user-specified
'heartbeat' parameter exceeds the valid range, the driver clamps the
timeout to default 30s but fails to update the logged 'heartbeat' value,
resulting in misleading log output:
iTCO_wdt iTCO_wdt: timeout value out of range, using 30
iTCO_wdt iTCO_wdt: initialized. heartbeat=700 sec (nowayout=0)
After validating the range, update the 'heartbeat' value with the clamped
timeout value to ensure that log messages accurately reflect the actual
runtime parameters.

The hardware only supports timeouts slightly below 3mins, but by using
max_hw_heartbeat_ms we can let the kernel take care of supporting larger

Switching to max_hw_heartbeat_ms also means our set_timeout function now
needs to configure the hardware to the minimum of either the requested
timeout (in seconds) or the maximum supported by the user (in seconds).
