Pull x86 RFDS mitigation from Dave Hansen:
"RFDS is a CPU vulnerability that may allow a malicious userspace to
infer stale register values from kernel space. Kernel registers can
have all kinds of secrets in them so the mitigation is basically to
wait until the kernel is about to return to userspace and has user
values in the registers. At that point there is little chance of
kernel secrets ending up in the registers and the microarchitectural
state can be cleared.
This leverages some recent robustness fixes for the existing MDS
vulnerability. Both MDS and RFDS use the VERW instruction for
mitigation"

Pull MSI updates from Thomas Gleixner:
"Updates for the MSI interrupt subsystem and initial RISC-V MSI
support.
The core changes have been adopted from previous work which converted
ARM[64] to the new per device MSI domain model, which was merged to
support multiple MSI domain per device. The ARM[64] changes are being
worked on too, but have not been ready yet. The core and platform-MSI
changes have been split out to not hold up RISC-V and to avoid that
RISC-V builds on the scheduled for removal interfaces.
The core support provides new interfaces to handle wire to MSI bridges
in a straight forward way and introduces new platform-MSI interfaces
which are built on top of the per device MSI domain model.
Once ARM[64] is converted over the old platform-MSI interfaces and the
related ugliness in the MSI core code will be removed.
The actual MSI parts for RISC-V were finalized late and have been
post-poned for the next merge window.
Drivers:
- Add a new driver for the Andes hart-level interrupt controller
- Rework the SiFive PLIC driver to prepare for MSI suport
- Expand the RISC-V INTC driver to support the new RISC-V AIA
controller which provides the basis for MSI on RISC-V
- A few fixup for the fallout of the core changes"

RFDS is a CPU vulnerability that may allow userspace to infer kernel
stale data previously used in floating point registers, vector registers
and integer registers. RFDS only affects certain Intel Atom processors.
Intel released a microcode update that uses VERW instruction to clear
the affected CPU buffers. Unlike MDS, none of the affected cores support
SMT.
Add RFDS bug infrastructure and enable the VERW based mitigation by
default, that clears the affected buffers just before exiting to
userspace. Also add sysfs reporting and cmdline parameter
"reg_file_data_sampling" to control the mitigation.
For details see:

Since commit 43a7206b0963 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the block_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically
allocated at boot time.

- devlink fixes for reported issues with 6.8-rc1
- topology scheduling regression fix that has been reported by many
- kobject loosening of checks change in -rc1 is now reverted as some
codepaths seemed to need the checks
- documentation update for the CVE process. Has been reviewed by
many, the last minute change to the document was to bring the .rst
format back into the the new style rules, the contents did not
change.
All of these, except for the documentation update, have been in
linux-next for over a week. The documentation update has been reviewed
for weeks by a group of developers, and in public for a week and the
wording has stabilized for now. If future changes are needed, we can

Provide functions to create and remove per device MSI domains which replace
the platform-MSI domains. The new model is that each of the devices which
utilize platform-MSI gets now its private MSI domain which is "customized"
in size and with a device specific function to write the MSI message into
the device.
This is the same functionality as platform-MSI but it avoids all the down
sides of platform MSI, i.e. the extra ID book keeping, the special data
structure in the msi descriptor. Further the domains are only created when
the devices are really in use, so the burden is on the usage and not on the
infrastructure.
Fill in the domain template and provide two functions to init/allocate and
remove a per device MSI domain.
Until all users and parent domain providers are converted, the init/alloc
function invokes the original platform-MSI code when the irqdomain which is
associated to the device does not provide MSI parent functionality yet.

During the cache sync test we verify that values we expect to have been
written only to the cache do not appear in the hardware. This works most
of the time but since we randomly generate both the original and new values
there is a low probability that these values may actually be the same.
Wrap get_random_bytes() to ensure that the values are different, there
are other tests which should have similar verification that we actually
changed something.
While we're at it refactor the test to use three changed values rather
than attempting to use one of them twice, that just complicates checking
that our new values are actually new.
We use random generation to try to avoid data dependencies in the tests.

The raw noinc write test places a known value in the register following
the noinc register to verify that it is not disturbed by the noinc
write. This test ensures this value is distinct by adding 100 to the
second element of the noinc write data.
The regmap registers are 16-bit, while the test value is stored in an
unsigned int. Therefore, adding 100 may cause the register to wrap while
the test value does not, causing the test to fail. This patch fixes this
by changing val_test and val_last from unsigned int to u16.

The links in a cycle are not all logged in a consistent manner or not
logged at all. Make them consistent by adding a "cycle:" string and log all
the link in the cycles (even the child ==> parent dependency) so that it's
easier to debug cycle detection code. Also, mark the start and end of a
cycle so it's easy to tell when multiple cycles are logged back to back.

fw_devlink can detect most overlapping/intersecting cycles. However it was
missing a few corner cases because of an incorrect optimization logic that
tries to avoid repeating cycle detection for devices that are already
marked as part of a cycle.
Here's an example provided by Xu Yang (edited for clarity):
usb
+-----+
tcpc | |
+-----+ | +--|
| |----------->|EP|
|--+ | | +--|
|EP|<-----------| |
|--+ | | B |
| | +-----+
| A | |
+-----+ |
^ +-----+ |
| | | |
+-----| C |<--+
| |
+-----+
usb-phy
Node A (tcpc) will be populated as device 1-0050.
Node B (usb) will be populated as device 38100000.usb.
Node C (usb-phy) will be populated as device 381f0040.usb-phy.
The description below uses the notation:
consumer --> supplier
child ==> parent
1. Node C is populated as device C. No cycles detected because cycle
detection is only run when a fwnode link is converted to a device link.
2. Node B is populated as device B. As we convert B --> C into a device
link we run cycle detection and find and mark the device link/fwnode
link cycle:
C--> A --> B.EP ==> B --> C
3. Node A is populated as device A. As we convert C --> A into a device
link, we see it's already part of a cycle (from step 2) and don't run
cycle detection. Thus we miss detecting the cycle:
A --> B.EP ==> B --> A.EP ==> A
Looking at it another way, A depends on B in one way:
A --> B.EP ==> B
But B depends on A in two ways and we only detect the first:
B --> C --> A
B --> A.EP ==> A
To detect both of these, we remove the incorrect optimization attempt in
step 3 and run cycle detection even if the fwnode link from which the
device link is being created has already been marked as part of a cycle.

device_link_flag_is_sync_state_only() correctly returns true on the flags
of an existing device link that only implements sync_state() functionality.
However, it incorrectly and confusingly returns false if it's called with
DL_FLAG_SYNC_STATE_ONLY.
This bug doesn't manifest in any of the existing calls to this function,
but fix this confusing behavior to avoid future bugs.

Pull CXL (Compute Express Link) updates from Dan Williams:
"The bulk of this update is support for enumerating the performance
capabilities of CXL memory targets and connecting that to a platform
CXL memory QoS class. Some follow-on work remains to hook up this data

The next significant update is unifying how CXL event records (things
like background scrub errors) are processed between so called
"firmware first" and native error record retrieval. The CXL driver
handler that processes the record retrieved from the device mailbox is
now the handler for that same record format coming from an EFI/ACPI
notification source.

Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.
Core & protocols:
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes
This improves TCP performances with many concurrent connections up
to 40%
- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID
- Implement SMCv2.1 virtual ISM device support
- Add support for Batman-avd mulicast packet type
BPF:
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques
- Support uid/gid options when mounting bpffs
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id
- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter
- Support for VLAN tag in XDP hints
- Remove deprecated bpfilter kernel leftovers given the project is
developed in user-space (https://github.com/facebook/bpfilter)
Misc:
- Support for parellel TC self-tests execution
- Increase MPTCP self-tests coverage
- Updated the bridge documentation, including several so-far
undocumented features
- Convert all the net self-tests to run in unique netns, to avoid
random failures due to conflict and allow concurrent runs
- Add TCP-AO self-tests
- Add kunit tests for both cfg80211 and mac80211
- Autogenerate Netlink families documentation from YAML spec
- Add yml-gen support for fixed headers and recursive nests, the tool
can now generate user-space code for all genetlink families for
which we have specs
- A bunch of additional module descriptions fixes
- Catch incorrect freeing of pages belonging to a page pool
Driver API:
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host
- Add support for ethtool symmetric-xor RSS hash
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute

Before commit 7839d0078e0d ("PM: sleep: Fix possible deadlocks in core
system-wide PM code"), the resume of devices that were allowed to resume
asynchronously was scheduled before starting the resume of the other
devices, so the former did not have to wait for the latter unless
functional dependencies were present.
Commit 7839d0078e0d removed that optimization in order to address a
correctness issue, but it can be restored with the help of a new device
power management flag, so do that now.

Pull power management updates from Rafael Wysocki:
"These add support for new processors (Sierra Forest, Grand Ridge and
Meteor Lake) to the intel_idle driver, make intel_pstate run on
Emerald Rapids without HWP support and adjust it to utilize EPP values
supplied by the platform firmware, fix issues, clean up code and
improve documentation.
The most significant fix addresses deadlocks in the core system-wide
resume code that occur if async_schedule_dev() attempts to run its
argument function synchronously (for example, due to a memory
allocation failure). It rearranges the code in question which may
increase the system resume time in some cases, but this basically is a
removal of a premature optimization. That optimization will be added
back later, but properly this time.
Specifics:
- Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)
- Do not enable interrupts when entering idle in the haltpoll cpuidle
driver (Borislav Petkov)

overflows (Christian Marangi)
- Synchronize devfreq_monitor_[start/stop] so as to prevent a timer

commit 23baf831a32c ("mm, treewide: redefine MAX_ORDER sanely") has
changed the definition of MAX_ORDER to be inclusive. This has caused
issues with code that was not yet upstream and depended on the previous
definition.
To draw attention to the altered meaning of the define, rename MAX_ORDER
to MAX_PAGE_ORDER.

The lock_class_key is still registered and can be found in
lock_keys_hash hlist after subsys_private is freed in error
handler path.A task who iterate over the lock_keys_hash
later may cause use-after-free.So fix that up and unregister
the lock_class_key before kfree(cp).
On our platform, a driver fails to kset_register because of
creating duplicate filename '/class/xxx'.With Kasan enabled,
it prints a invalid-access bug report.
KASAN bug report:

As CONFIG_KASAN_GENERIC is not set, Kasan reports invalid-access
not use-after-free here.In this case, modprobe is manipulating
the corrupted lock_keys_hash hlish where lock_class_key is already
freed before.
It's worth noting that this only can happen if lockdep is enabled,
which is not true for normal system.

The driver core wants to work with const struct bus_type, so there's no
reason that pm_clk_add_notifier() should not also do the same thing,
considering that it just passes the pointer off to the driver core which

It is reported that in low-memory situations the system-wide resume core
code deadlocks, because async_schedule_dev() executes its argument
function synchronously if it cannot allocate memory (and not only in
that case) and that function attempts to acquire a mutex that is already
held. Executing the argument function synchronously from within
dpm_async_fn() may also be problematic for ordering reasons (it may
cause a consumer device's resume callback to be invoked before a
requisite supplier device's one, for example).
Address this by changing the code in question to use
async_schedule_dev_nocall() for scheduling the asynchronous
execution of device suspend and resume functions and to directly
run them synchronously if async_schedule_dev_nocall() returns false.

Use the new capacity_ref_freq() method to set the ratio that is used by AMU for
computing the arch_scale_freq_capacity().
This helps to keep everything aligned using the same reference for
computing CPUs capacity.
The default value of the ratio (stored in per_cpu(arch_max_freq_scale))
ensures that arch_scale_freq_capacity() returns max capacity until it is
set to its correct value with the cpu capacity and capacity_ref_freq().

Create a new method to get a unique and fixed max frequency. Currently
cpuinfo.max_freq or the highest (or last) state of performance domain are
used as the max frequency when computing the frequency for a level of
utilization, but:
- cpuinfo_max_freq can change at runtime. boost is one example of
such change.
- cpuinfo.max_freq and last item of the PD can be different leading to
different results between cpufreq and energy model.
We need to save the reference frequency that has been used when computing
the CPUs capacity and use this fixed and coherent value to convert between
frequency and CPU's capacity.
In fact, we already save the frequency that has been used when computing
the capacity of each CPU. We extend the precision to save kHz instead of
MHz currently and we modify the type to be aligned with other variables
used when converting frequency to capacity and the other way.

Dan Williams suggested changing the struct 'node_hmem_attrs' to
'access_coordinates' [1]. The struct is a container of r/w-latency and
r/w-bandwidth numbers. Moving forward, this container will also be used by
CXL to store the performance characteristics of each link hop in
the PCIE/CXL topology. So, where node_hmem_attrs is just the access
parameters of a memory-node, access_coordinates applies more broadly
to hardware topology characteristics. The observation is that seemed like
an exercise in having the application identify "where" it falls on a
spectrum of bandwidth and latency needs. For the tuple of
read/write-latency and read/write-bandwidth, "coordinates" is not a perfect
fit. Sometimes it is just conveying values in isolation and not a
"location" relative to other performance points, but in the end this data
is used to identify the performance operation point of a given memory-node.

The functions subsys_register() and subsys_virtual_register() should be
taking a constant pointer to a struct bus_type, as they do not actually
modify anything in it, so fix up the function definitions to do so
properly.
This also changes the pointer type in struct subsys_interface to be
constant as well, as again, that's the proper signature of it.

When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed a bunch of four similar warnings like:
drivers/base/regmap/regmap-ram.c: In function '__regmap_init_ram':
drivers/base/regmap/regmap-ram.c:68:37: warning: 'kcalloc' sizes specified with
'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
68 | data->read = kcalloc(sizeof(bool), config->max_register + 1,
| ^~~~
Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.

ti,hdc3020
* New driver for this integrated relative humidity and temperature
sensor.
vishay,veml6075
* New driver for this UVA and UVB light sensor.
General features
----------------
Device properties
* Add fwnode_property_match_property_string() helper to allow matching
single value property against an array of predefined strings.
* Use fwnode_property_string_array_count() inside
fwnode_property_match_string() instead of open coding the same.
checkpatch.pl
* Add exclusion of __aligned() from a warning reducing false positives
on IIO drivers (and hopefully beyond)
IIO Features
------------
core
* New light channel modifiers for UVA and UVB.
* Add IIO_CHAN_INFO_TROUGH as counterpart to IIO_CHAN_INFO_PEAK so that
we can support device that keep running track of the lowest value they
have seen in similar fashion to the existing peak tracking.
adi,adis library
* Use spi cs inactive delay even when a burst reading is performed.
As it's now used every time, can centralize the handling in the SPI
setup code in the driver.
adi,ad2s1210
* Support for fixed-mode to this resolver driver where the A0 and A1
pins are hard wired to config mode in which case position and config
must be read from appropriate config registers.
* Support reset GPIO if present.
adi,ad5791
* Allow configuration of presence of external amplifier in DT binding.
adi,adis16400
* Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked
if default delays are not quite enough for a specific board.
adi,adis16475
* Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked
if default delays are not quite enough for a specific board.
bosch,bmp280
* Enable multiple chip IDs per family of devices.
rohm,bu27008
* Add an illuminance channel calculated from RGB and IR data.
Cleanup
-------
Minor white space, typos and tidy up not explicitly called out.
Core
* Check that the available_scan_masks array passed to the IIO core
by a driver is sensible by ensuring the entries are ordered so the
minimum number of channels is enabled in the earlier entries (as they
will be selected if sufficient for the requested channels).
* Document that the available_scan_masks infrastructure doesn't currently
handle masks that don't fit in a long int.
* Improve intensity documentation to reflect that there is no expectation
of sensible units (it's dependent on a frequency sensitivity curve)
Various
* Use new device_property_match_property_string() to replace open coded
versions of the same thing.
* Fix a few MAINTAINERS filenames.
* i2c_get_match_data() and spi_get_device_match_data() pushed into
more drivers reducing boilerplate handling.
* Some unnecessary headers removed.
* ACPI_PTR() removals. It's rarely worth using this.
adi,ad7091r (early part of a series adding device support - useful in
their own right)
* Pass iio_dev directly an event handler rather than relying
on broken use of dev_get_drvdata() as drvdata is never set in this driver.
* Make sure alert is turned on.
adi,ad9467 (general driver fixing up as precursor to iio-backend proposal
which is under review for 6.9)
* Fix reset gpio handling to match expected polarity.
* Always handle error codes from spi_writes.
* Add a driver instance local mutex to avoid some races.
* Fix scale setting to align with available scale values.
* Split array of chip_info structures up into named individual elements.
* Convert to regmap.
honeywell,mprls0025pa
* Drop now unnecessary type references in DT binding for properties in
pascals.
invensense,mpu6050
* Don't eat a potentially useful return value from regmap_bulk_write()
invensense,icm42600
* Use max macro to improve code readability and save a few lines.
liteon,ltrf216a
* Improve prevision of light intensity.
microchip,mcp3911
* Use cleanup.h magic.
qcom,spmi*
* Fix wrong descriptions of SPMI reg fields in bindings.

It seems reasonable to collect the core parts for the generic PM domain,
along with its corresponding provider drivers. Therefore let's move the
files from drivers/base/power/ to drivers/pmdomain/ and while at it, let's
also rename the files accordingly.
Moreover, let's also update MAINTAINERS to reflect the update.

Specs don't say anything about UIP being cleared within 10ms. They
only say that UIP won't occur for another 244uS. If a long NMI occurs
while UIP is still updating it might not be possible to get valid
data in 10ms.
This has been observed in the wild that around s2idle some calls can
take up to 480ms before UIP is clear.
Adjust callers from outside an interrupt context to wait for up to a
1s instead of 10ms.

The UIP timeout is hardcoded to 10ms for all RTC reads, but in some
contexts this might not be enough time. Add a timeout parameter to
mc146818_get_time() and mc146818_get_time_callback().
If UIP timeout is configured by caller to be >=100 ms and a call
takes this long, log a warning.
Make all callers use 10ms to ensure no functional changes.
