Core code:
- Cure a couple of incorrectness issues in the posix CPU timer code to
prevent that the tick dependency for NOHZ full is kept alive for no
reason.
- Avoid expensive double reprogramming of the clockevent device in
hrtimer_start_range_ns().
- Avoid pointless SMP function calls when the clock was set to avoid
disturbing CPUs which do not have any affected timers queued.
- Make the clocksource watchdog test work correctly when CONFIG_HZ is
less than 100.
Drivers:
- Prefer the ARM architected timer over the Exynos timer which is way
more expensive to access.
- Add device tree bindings for new Ingenic SoCs
- The usual improvements and cleanups all over the place

The regular pile:
- A few improvements to the mutex code
- Documentation updates for atomics to clarify the difference between
cmpxchg() and try_cmpxchg() and to explain the forward progress
expectations.
- Simplification of the atomics fallback generator
- The addition of arch_atomic_long*() variants and generic arch_*()
bitops based on them.
- Add the missing might_sleep() invocations to the down*() operations of
semaphores.
The PREEMPT_RT locking core:
- Scheduler updates to support the state preserving mechanism for
'sleeping' spin- and rwlocks on RT. This mechanism is carefully
preserving the state of the task when blocking on a 'sleeping' spin- or
rwlock and takes regular wake-ups targeted at the same task into
account. The preserved or updated (via a regular wakeup) state is
restored when the lock has been acquired.
- Restructuring of the rtmutex code so it can be utilized and extended
for the RT specific lock variants.
- Restructuring of the ww_mutex code to allow sharing of the ww_mutex
specific functionality for rtmutex based ww_mutexes.
- Header file disentangling to allow substitution of the regular lock
implementations with the PREEMPT_RT variants without creating an
unmaintainable #ifdef mess.
- Shared base code for the PREEMPT_RT specific rw_semaphore and rwlock
implementations. Contrary to the regular rw_semaphores and rwlocks the
PREEMPT_RT implementation is writer unfair because it is infeasible to
do priority inheritance on multiple readers. Experience over the years
has shown that real-time workloads are not the typical workloads which
are sensitive to writer starvation. The alternative solution would be
to allow only a single reader which has been tried and discarded as it
is a major bottleneck especially for mmap_sem. Aside of that many of
the writer starvation critical usage sites have been converted to a
writer side mutex/spinlock and RCU read side protections in the past
decade so that the issue is less prominent than it used to be.
- The actual rtmutex based lock substitutions for PREEMPT_RT enabled
kernels which affect mutex, ww_mutex, rw_semaphore, spinlock_t and
rwlock_t. The spin/rw_lock*() functions disable migration across the
critical section to preserve the existing semantics vs. per CPU
variables.
- Rework of the futex REQUEUE_PI mechanism to handle the case of early
wake-ups which interleave with a re-queue operation to prevent the
situation that a task would be blocked on both the rtmutex associated
to the outer futex and the rtmutex based hash bucket spinlock.
While this situation cannot happen on !RT enabled kernels the changes
make the underlying concurrency problems easier to understand in
general. As a result the difference between !RT and RT kernels is
reduced to the handling of waiting for the critical section. !RT
kernels simply spin-wait as before and RT kernels utilize rcu_wait().
- The substitution of local_lock for PREEMPT_RT with a spinlock which
protects the critical section while staying preemptible. The CPU
locality is established by disabling migration.
The underlying concepts of this code have been in use in PREEMPT_RT for
way more than a decade. The code has been refactored several times over
the years and this final incarnation has been optimized once again to be
as non-intrusive as possible, i.e. the RT specific parts are mostly
isolated.
It has been extensively tested in the 5.14-rt patch series and it has
been verified that !RT kernels are not affected by these changes.

"RCU changes for this cycle were:
- Documentation updates
- Miscellaneous fixes
- Offloaded-callbacks updates
- Updates to the nolibc library
- Tasks-RCU updates
- In-kernel torture-test updates
- Torture-test scripting, perhaps most notably the pinning of
torture-test guest OSes so as to force differences in memory
latency. For example, in a two-socket system, a four-CPU guest OS
will have one pair of its CPUs pinned to threads in a single core
on one socket and the other pair pinned to threads in a single core
on the other socket. This approach proved able to force race
conditions that earlier testing missed. Some of these race
conditions are still being tracked down"

Fix the use of nents and orig_nents in the sg table append helpers. The
nents should be used by the DMA layer to store the number of DMA mapped
sges, the orig_nents is the number of CPU sges.
Since the sg append logic doesn't always create a SGL with exactly
orig_nents entries store a total_nents as well to allow the table to be
properly free'd and reorganize the freeing logic to share across all the
use cases.

'enum' is equivalent to 'oneOf' with a list of 'const' entries, but 'enum'

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next:
1) Clean up and consolidate ct ecache infrastructure by merging ct and
expect notifiers, from Florian Westphal.
2) Missing counters and timestamp in nfnetlink_queue and _log conntrack
information.
3) Missing error check for xt_register_template() in iptables mangle,
as a incremental fix for the previous pull request, also from
Florian Westphal.
4) Add netfilter hooks for the SRv6 lightweigh tunnel driver, from
Ryoga Sato. The hooks are enabled via nf_hooks_lwtunnel sysctl
to make sure existing netfilter rulesets do not break. There is
a static key to disable the hooks by default.
The pktgen_bench_xmit_mode_netif_receive.sh shows no noticeable
impact in the seg6_input path for non-netfilter users: similar
numbers with and without this patch.
This is a sample of the perf report output:

conntrack has two distinct table size settings:
nf_conntrack_max and nf_conntrack_buckets.
The former limits how many conntrack objects are allowed to exist
in each namespace.
The second sets the size of the hashtable.
As all entries are inserted twice (once for original direction, once for
reply), there should be at least twice as many buckets in the table than
the maximum number of conntrack objects that can exist at the same time.
Change the default multiplier to 1 and increase the chosen bucket sizes.
This results in the same nf_conntrack_max settings as before but reduces
the average bucket list length.

To improve the user's ability to debug the case where a workload that
is part of executing training/inference of a topology is getting stuck,
we need to add a 'core dump' each time a CS times-out. The 'core dump'
shall contain all relevant Sync Manager information and corresponding
fence values.
The most recent dumps shall be accessible via debugfs, under
'state_dump' node. Reading from the node will provide the oldest dump
available. Writing an integer value X will discard X dumps, starting
with the oldest one, i.e. subsequent read will now return newer

This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.
Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.
Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.
The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.
This driver has been tested on x86_64, both in-kernel and as a module.

There are two independent PCIe controllers in MT2712 and MT7622
platform. Each of them should contain an independent MSI domain.
In old dts architecture, MSI domain will be inherited from the root
bridge, and all of the devices will share the same MSI domain.
Hence that, the PCIe devices will not work properly if the irq number
which required is more than 32.
Split the PCIe node for MT2712 and MT7622 platform to comply with
the hardware design and fix MSI issue.

calculated from the frame counter clock 24Mhz by default, but
in fact, the frame counter clock is 48Mhz, so we should set
the accurate interval according to 48Mhz. Here add a new compatible
for MT8195, it's also supported in driver. But the first controller

There are two methods to specify the location of the elf core headers:
using the "elfcorehdr=" kernel parameter, as handled by generic code in
kernel/crash_dump.c, or using the "linux,elfcorehdr" property under the
"/chosen" node in the Device Tree, as handled by architecture-specific
code in arch/arm64/mm/init.c.
Extend support for "linux,elfcorehdr" to all platforms supporting DT by
adding platform-agnostic handling for handling this property to the FDT
core code. This can co-exist safely with the architecture-specific
handling, until the latter has been removed.
This requires moving the call to of_scan_flat_dt() up, as the code
scanning the "/chosen" node now needs to be aware of the values of
"#address-cells" and "#size-cells".

We added CONFIG_MANDATORY_FILE_LOCKING in 2015, and soon after turned it
off in Fedora and RHEL8. Several other distros have followed suit.
I've heard of one problem in all that time: Someone migrated from an
older distro that supported "-o mand" to one that didn't, and the host
had a fstab entry with "mand" in it which broke on reboot. They didn't
actually _use_ mandatory locking so they just removed the mount option
and moved on.
This patch rips out mandatory locking support wholesale from the kernel,
along with the Kconfig option and the Documentation file. It also
changes the mount code to ignore the "mand" mount option instead of
erroring out, and to throw a big, ugly warning.

The ima documentation for measuring DM targets (dm-ima.rst) is
missing the attribute information for the targets - 'cache', 'integrity',
'multipath', and 'snapshot'. It is also missing the grammar for
various DM events and targets, which can help the attestation servers
to determine what data to expect for a given DM device. Further,
the documentation needs to be updated to incorporate code changes
made to DM ima events and targets as part of this patch series. For
instance, prefixing the event names with "dm_", adding the DM version to
events, prefixing the table hashes in the ima log with the
hash algorithm etc. There are warnings reported by 'make htmldocs' on
dm-ima.rst, which need to be fixed. And lastly, the expected behavior
needs to be documented when the configuration CONFIG_IMA_DISABLE_HTABLE
is disabled.
Update the documentation to add examples for 'cache', 'integrity',
'multipath', and 'snapshot' targets. Add the grammar for
various DM events and targets in Backus Naur form,
so that the attestation servers can interpret and act on the ima
measurements for DM target. Fix htmldocs warnings in dm-ima.rst. Update
the documentation to be consistent with the code changes that are part of

KVM_GUESTDBG_BLOCKIRQ will allow KVM to block all interrupts
while running.
This change is mostly intended for more robust single stepping
of the guest and it has the following benefits when enabled:
* Resuming from a breakpoint is much more reliable.
When resuming execution from a breakpoint, with interrupts enabled,
more often than not, KVM would inject an interrupt and make the CPU
jump immediately to the interrupt handler and eventually return to
the breakpoint, to trigger it again.
From the user point of view it looks like the CPU never executed a
single instruction and in some cases that can even prevent forward
progress, for example, when the breakpoint is placed by an automated
script (e.g lx-symbols), which does something in response to the
breakpoint and then continues the guest automatically.
If the script execution takes enough time for another interrupt to
arrive, the guest will be stuck on the same breakpoint RIP forever.
* Normal single stepping is much more predictable, since it won't
land the debugger into an interrupt handler.
* RFLAGS.TF has less chance to be leaked to the guest:
We set that flag behind the guest's back to do single stepping
but if single step lands us into an interrupt/exception handler
it will be leaked to the guest in the form of being pushed
to the stack.
This doesn't completely eliminate this problem as exceptions
can still happen, but at least this reduces the chances
of this happening.

x86_64 vmalloc() mappings are no longer "synchronized" among page tables
via faulting since commit 6eb82f9940 ("x86/mm: Pre-allocate P4D/PUD
pages for vmalloc area"), since the corresponding P4D or PUD pages are
now preallocated at boot, by preallocate_vmalloc_pages(). Drop the
"lazily synchronized" description for less confusion.
While this file is x86_64-specific, it is worth noting that things are
different for x86_32, where vmalloc()-related changes to `init_mm.pgd` are
synchronized to all page tables in the system during runtime, via
arch_sync_kernel_mappings(). Unfortunately, this synchronization is
subject to race condition, which is further handled via faulting, see
vmalloc_fault(). See commit 4819e15f74 ("x86/mm/32: Bring back vmalloc
faulting on x86_32") for more details.

This series introduces the support for two new mlx5 features:
1) Sample offload for tunneled traffic
2) devlink rate objects support
1) From Chris Mi: Sample offload for tunneled traffic
=====================================================
Background and solution
-----------------------
Currently the sample offload actions send the encapsulated packet
to software. This series de-capsulates the packet before performing
the sampling and set the tunnel properties on the skb metadata
fields to make the behavior consistent with OVS sFlow.
If de-capsulating first, we can't use the same match like before in
default table. So instantiate a post action instance to continue
processing the action list. If HW can preserve reg_c, also use the
post action instance.
Post action infrastructure
--------------------------
Some tc actions are modeled in hardware using multiple tables
causing a tc action list split. For example, CT action is modeled
by jumping to a ct table which is controlled by nf flow table.
sFlow jumps in hardware to a sample table, which continues to a
"default table" where it should continue processing the action list.
Multi table actions are modeled in hardware using a unique fte_id.
The fte_id is set before jumping to a table. Split actions continue
to a post-action table where the matched fte_id value continues the
execution the tc action list.
This series also introduces post action infrastructure. Both ct and
sample use it.

2) From Dmytro Linkin: devlink rate object support for mlx5_core driver
=======================================================================
HIGH-LEVEL OVERVIEW
Devlink leaf rate objects created per vport (VF/SF, and PF on BlueField)
in switchdev mode on devlink port registration.
Implement devlink ops callbacks to create/destroy rate groups, set TX
rate values of the vport/group, assign vport to the group.
Driver accepts TX rate values as fraction of 1Mbps.
Refactor existing eswitch QoS infrastructure to be accessible by legacy
NDO rate API and new devlink rate API. NDO rate API is not
removed/disabled in switchdev mode to not break existing users. Rate
values configured with NDO rate API are not visible for devlink
infrastructure, therefore APIs should not be used simultaneously.
IMPLEMENTATION DETAILS
Driver provide two level rate hierarchy to manage bandwidth - group
level and vport level. Initially each vport added to internal unlimited
group created by default. Each rate element (vport or group) receive
bandwidth relative to its parent element (for groups the parent is a
physical link itself) in a Round Robin manner, where element get
bandwidth value according to its weight. Example:
Created four rate groups with tx_share limits:
$ devlink port function rate add \
pci/0000:06:00.0/group_1 tx_share 30gbit
$ devlink port function rate add \
pci/0000:06:00.0/group_2 tx_share 20gbit
$ devlink port function rate add \
pci/0000:06:00.0/group_3 tx_share 20gbit
$ devlink port function rate add \
pci/0000:06:00.0/group_4 tx_share 10gbit
Weights created in HW for each group are relative to the bigest tx_share
value, which is 30gbit:
<group_1> 1.0
<group_2> 0.67
<group_3> 0.67
<group_4> 0.33
Assuming link speed is 50 Gbit/sec and each group can sustain such
amount of traffic, maximum bandwidth is 50 / (1.0 + 0.67 + 0.67 + 0.33)
= ~18.75 Gbit/sec. Normilized bandwidth values for groups:
<group_1> 18.75 * 1.0 = 18.75 Gbit/sec
<group_2> 18.75 * 0.67 = 12.5 Gbit/sec
<group_3> 18.75 * 0.67 = 12.5 Gbit/sec
<group_4> 18.75 * 0.33 = 6.25 Gbit/sec
If in example above group_1 doesn't produce any traffic, then maximum
bandwidth becomes 50 / (0.67 + 0.67 + 0.33) = ~30.0 Gbit/sec. Normalized
values:
<group_2> 30.0 * 0.67 = 20.0 Gbit/sec
<group_3> 30.0 * 0.67 = 20.0 Gbit/sec
<group_4> 30.0 * 0.33 = 10.0 Gbit/sec
Same normalization applied to each vport in the group.
Normalized values are internal, therefore driver provides QoS
tracepoints for next events:
* vport rate element creation/deletion:
* vport rate element configuration;
* group rate element creation/deletion;
* group rate element configuration.
PATCHES OVERVIEW
1 - Moving and isolation of eswitch QoS logic in separate file;
2 - Implement devlink leaf rate object support for vports;
3 - Implement rate groups creation/deletion;
4 - Implement TX rate management for the groups;
5 - Implement parent set for vports;

When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
compilers (i.e., at least gcc 8.4.0) decided to compile this
inline. This is a problem for lkdtm.ko, which inserted a kprobe
on this function for the SCSI_DISPATCH_CMD crashpoint.
Move this crashpoint one function up the call chain to
scsi_queue_rq. Though this is also a static function, it should never be
inlined because it is assigned as a structure entry. Therefore,
kprobe_register should always be able to find it.

This patch renames a documentation libbpf.rst to index.rst. In order
for readthedocs.org to pick this file up and properly build the
documentation site.
It also changes the title type of the ABI subsection in the
naming convention doc. This is so that readthedocs.org doesn't treat this
section as a separate document.

This fixes the "shared memory state machine" (SMSM) interrupt logic to
avoid missing transitions happening while the interrupts are masked.
SM6115 support is added to smd-rpm and rpmpd.
The Qualcomm SCM firmware driver is once again made possible to compile
and load as a kernel module.
An out-of-bounds error related to the cooling devices of the AOSS driver
is corrected. The binding is converted to YAML and a generic compatible
is introduced to reduce the driver churn.
The GENI wrapper gains a helper function used in I2C and SPI for
switching the serial engine hardware to use the wrapper's DMA-engine.
Lastly it contains a number of cleanups and smaller fixes for rpmhpd,
socinfo, CPR, mdt_loader and the GENI DT binding.

The sysfs interface for default domain types exists primarily so users
can choose the performance/security tradeoff relevant to their own
workload. As such, the choice between the policies for DMA domains fits
perfectly as an additional point on that scale - downgrading a
particular device from a strict default to non-strict may be enough to
let it reach the desired level of performance, while still retaining
more peace of mind than with a wide-open identity domain. Now that we've
abstracted non-strict mode as a distinct type of DMA domain, allow it to
be chosen through the user interface as well.

It is possible that a directory tree is shared between multiple overlay
instances as a lower layer. In this case when one instance executes a file
residing on the lower layer, the other instance denies a truncate(2) call
on this file.
This only happens for truncate(2) and not for open(2) with the O_TRUNC
flag.
Fix this interference and inconsistency by removing the preliminary
i_writecount check before copy-up.
This means that unlike on normal filesystems truncate(argv[0]) will now
succeed. If this ever causes a regression in a real world use case this
needs to be revisited.
One way to fix this properly would be to keep a correct i_writecount in the
overlay inode, but that is difficult due to memory mapping code only
dealing with the real file/inode.

This removes the libbpf_api.rst file from the kernel documentation.
The intention for this file was to pull documentation from comments
above API functions in libbpf. However, due to limitations of the
kernel documentation system, this API documentation could not be
versioned, which is counterintuative to how users expect to use it.
There is also currently no doc comments, making this a blank page.
Once the kernel comment documentation is actually contributed, it
will still exist in the kernel repository, just in the code itself.
A seperate site is being spun up to generate documentaiton from those
comments in a way in which it can be versioned properly.
This also reconfigures the bpf documentation index page to make it
easier to sync to the previously mentioned documentaiton site.

Turn BPF_PROG_RUN into a proper always inlined function. No functional and
performance changes are intended, but it makes it much easier to understand
what's going on with how BPF programs are actually get executed. It's more
obvious what types and callbacks are expected. Also extra () around input
parameters can be dropped, as well as `__` variable prefixes intended to avoid
naming collisions, which makes the code simpler to read and write.
This refactoring also highlighted one extra issue. BPF_PROG_RUN is both
a macro and an enum value (BPF_PROG_RUN == BPF_PROG_TEST_RUN). Turning
BPF_PROG_RUN into a function causes naming conflict compilation error. So
rename BPF_PROG_RUN into lower-case bpf_prog_run(), similar to
bpf_prog_run_xdp(), bpf_prog_run_pin_on_cpu(), etc. All existing callers of
BPF_PROG_RUN, the macro, are switched to bpf_prog_run() explicitly.

While users can restrict the accepted hash algorithms for the
security.ima xattr file signature when appraising said file, users
cannot restrict the algorithms that can be set on that attribute:
any algorithm built in the kernel is accepted on a write.
Define a new value for the ima policy option 'func' that restricts
globally the hash algorithms accepted when writing the security.ima
xattr.
When a policy contains a rule of the form
appraise func=SETXATTR_CHECK appraise_algos=sha256,sha384,sha512
only values corresponding to one of these three digest algorithms
will be accepted for writing the security.ima xattr. Attempting to
write the attribute using another algorithm (or "free-form" data)
will be denied with an audit log message. In the absence of such a
policy rule, the default is still to only accept hash algorithms
built in the kernel (with all the limitations that entails).

The kernel has the ability to restrict the set of hash algorithms it
accepts for the security.ima xattr when it appraises files.
Define a new IMA policy rule option "appraise_algos=", using the
mentioned mechanism to expose a user-toggable policy knob to opt-in
to that restriction and select the desired set of algorithms that
must be accepted.
When a policy rule uses the 'appraise_algos' option, appraisal of a
file referenced by that rule will now fail if the digest algorithm
employed to hash the file was not one of those explicitly listed in
the option. In its absence, any hash algorithm compiled in the
kernel will be accepted.
For example, on a system where SELinux is properly deployed, the rule
appraise func=BPRM_CHECK obj_type=iptables_exec_t \
appraise_algos=sha256,sha384
will block the execution of iptables if the xattr security.ima of its
executables were not hashed with either sha256 or sha384.

Drivers like thinkpad_acpi and ideapad_laptop call the
platform_profile_notify() helper when the profile is changed by hardware
(the embedded-controller/EC) in response to an EC handled hotkey.
This allows userspace to monitor for such changes by polling for POLLPRI
on the platform_profile sysfs file. But the profile can also be changed
underneath a userspace program monitoring it by anonther userspace program
storing a new value.
Add a sysfs_notify() call to platform_profile_store(), so that userspace
programs monitoring for changes also get notified in this case.
Also update the documentation to document that POLLPRI polling can be
used to watch for changes.

The Maxim 17042-family of fuel gauges are often embedded in other Maxim
chips, e.g. in Maxim 77693 which is a companion power management IC.
In such designs there might be actually two interrupts:
- INTB signaling change from charger, flash or MUIC,
- ALERT signaling change from fuel gauge.
Describe the interrupt in bindings to make it clear it is about the fuel
gauge ALERT interrupt, not the INT.

is redundant.
- Standardize error returns when limits are exceeded.
* 104-quad:
- Document the lock.
- Return an error if attempt to set the ceiling value in a mode that

- Add support fo the bosch,bmc156_accel which oddly only exposes the INT2
interrupt pin and not INT1. Patch set includes enabling use of INT2.

Even though the previous binding made it a required child node, the
implementation in Linux never made it mandatory and just ignored thermal
zones without trip points.
This was even effectively encouraged, since the thermal core wouldn't
allow a thermal sensor to probe without a thermal zone.
In the case where you had a thermal device that had multiple sensors but
with enough knowledge to provide trip points for only a few of them,
this meant that the only way to make that driver probe was to provide a
thermal zone without the trips node required by the binding.
This obviously led to a fair number of device trees doing exactly that,
making the initial binding requirement ineffective.
Let's make it clear by dropping that requirement.

The msk can use backup subflows to transmit in-sequence data
only if there are no other active subflow. On active backup
scenario, the MPTCP connection can do forward progress only
due to MPTCP retransmissions - rtx can pick backup subflows.
This patch introduces a new flag flow MPTCP subflows: if the
underlying TCP connection made no progresses for long time,
and there are other less problematic subflows available, the
given subflow become stale.
Stale subflows are not considered active: if all non backup
subflows become stale, the MPTCP scheduler can pick backup
subflows for plain transmissions.
Stale subflows can return in active state, as soon as any reply
from the peer is observed.
Active backup scenarios can now leverage the available b/w
with no restrinction.

--raw_output is nice, but it would be nicer if could show only output
after KUnit tests have started.
So change the flag to allow specifying a string ('kunit').
Make it so `--raw_output` alone will default to `--raw_output=all` and
have the same original behavior.
Drop the small kunit_parser.raw_output() function since it feels wrong
to put it in "kunit_parser.py" when the point of it is to not parse
anything.
E.g.
$ ./tools/testing/kunit/kunit.py run --raw_output=kunit

kunit.py currently does not make it possible for users to specify module
parameters (/kernel arguments more generally) unless one directly tweaks
the kunit.py code itself.
This hasn't mattered much so far, but this would make it easier to port
existing tests that expose module parameters over to KUnit and/or let
current KUnit tests take advantage of them.
Tested using an kunit internal parameter:
$ ./tools/testing/kunit/kunit.py run --kunitconfig=lib/kunit \
--kernel_args=kunit.filter_glob=kunit_status
...
Testing complete. 2 tests run. 0 failed. 0 crashed. 0 skipped.
