Pull regulator updates from Mark Brown:
"A fairly quiet release, there were some cleanup and a couple of new
devices but the biggest change was converting most of the drivers to
use asynchronous probe. This allows us to ramp up multiple regulators

- Update of drivers to PROBE_PREFER_ASYNCHRONOUS to mitigate issues
with ramp times slowing down boots.
- Convert to void remove callbacks.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"This is a much bigger change for regmap than is normal, the main
things being the addition of some KUnit coverage and a maple tree
based register cache which longer term is likely to replace the rbtree
cache except possibly for very small register maps.
While it's complete overkill for most applications the code for maple
trees is there and there are some larger, sparser devices where the
data structure is a better fit.
The maple tree support is still a work in progress but already useful,
there's some conversions of drivers ready to go after the merge
window.
Summary:
- Support for shifting register addresses up as well as down, there's
a use cases with memory mapped MDIO.
- Refactoring of the type configuration in regmap-irq to allow access
to driver data in the handler, needed by some GPIO devices.
- Some initial KUnit coverage, the bulk of the driver facing API is
covered but there's holes and things like the data marshalling for
bytestream buses are just not covered in the slightest.
- Removal of the compressed cache type, it had zero users and was
getting in the way of KUnit.
- Addition of a maple tree based register cache, there's more work to
do but it's already useful for some devices with a flatter data
structure than rbtree and getting to use all the optimisation work
Liam is doing"

Pull slab updates from Vlastimil Babka:
"The main change is naturally the SLOB removal. Since its deprecation
in 6.2 I've seen no complaints so hopefully SLUB_(TINY) works well for
everyone and we can proceed.
Besides the code cleanup, the main immediate benefit will be allowing
kfree() family of function to work on kmem_cache_alloc() objects,
which was incompatible with SLOB. This includes kfree_rcu() which had
no kmem_cache_free_rcu() counterpart yet and now it shouldn't be
necessary anymore.
Besides that, there are several small code and comment improvements
from Thomas, Thorsten and Vernon"

Pull arm64 updates from Will Deacon:
"ACPI:
- Improve error reporting when failing to manage SDEI on AGDI device
removal
Assembly routines:
- Improve register constraints so that the compiler can make use of
the zero register instead of moving an immediate #0 into a GPR
- Allow the compiler to allocate the registers used for CAS
instructions
CPU features and system registers:
- Cleanups to the way in which CPU features are identified from the
ID register fields
- Extend system register definition generation to handle Enum types
when defining shared register fields
- Generate definitions for new _EL2 registers and add new fields for
ID_AA64PFR1_EL1
- Allow SVE to be disabled separately from SME on the kernel
command-line
Tracing:
- Support for "direct calls" in ftrace, which enables BPF tracing for
arm64
Kdump:
- Don't bother unmapping the crashkernel from the linear mapping,
which then allows us to use huge (block) mappings and reduce TLB
pressure when a crashkernel is loaded.
Memory management:
- Try again to remove data cache invalidation from the coherent DMA
allocation path
- Simplify the fixmap code by mapping at page granularity
- Allow the kfence pool to be allocated early, preventing the rest of
the linear mapping from being forced to page granularity
Perf and PMU:
- Move CPU PMU code out to drivers/perf/ where it can be reused by
the 32-bit ARM architecture when running on ARMv8 CPUs
- Fix race between CPU PMU probing and pKVM host de-privilege
- Add support for Apple M2 CPU PMU
- Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event
dynamically, depending on what the CPU actually supports
- Minor fixes and cleanups to system PMU drivers
Stack tracing:
- Use the XPACLRI instruction to strip PAC from pointers, rather than
rolling our own function in C
- Remove redundant PAC removal for toolchains that handle this in
their builtins
- Make backtracing more resilient in the face of instrumentation
Miscellaneous:
- Fix single-step with KGDB
- Remove harmless warning when 'nokaslr' is passed on the kernel
command-line
- Minor fixes and cleanups across the board"

Pull ARM SoC devicetree updates from Arnd Bergmann:
"The devicetree changes overall are again dominated by the Qualcomm
Snapdragon platform that weighs in at over 300 changesets, but there
are many updates across other platforms as well, notably Mediatek,
NXP, Rockchips, Renesas, TI, Samsung and ST Microelectronics. These
all add new features for existing machines, as well as new machines
and SoCs.
The newly added SoCs are:
- Allwinner T113-s, an Cortex-A7 based variant of the RISC-V based D1
chip.
- StarFive JH7110, a RISC-V SoC based on the Sifive U74 core like its
JH7100 predecessor, but with additional CPU cores and a GPU.
- Apple M2 as used in current Macbook Air/Pro and Mac Mini gets
added, with comparable support as its M1 predecessor.
- Unisoc UMS512 (Tiger T610) is a midrange smartphone SoC
- Qualcomm IPQ5332 and IPQ9574 are Wi-Fi 7 networking SoCs, based on
the Cortex-A53 and Cortex-A73 cores, respectively.
- Qualcomm sa8775p is an automotive SoC derived from the Snapdragon
family.
Including the initial board support for the added SoC platforms, there
are 52 new machines. The largest group are 19 boards industrial
embedded boards based on the NXP i.MX6 (32-bit) and i.MX8 (64-bit)
families.
Others include:
- Two boards based on the Allwinner f1c200s ultra-low-cost chip
- Three 'Banana Pi' variants based on the Amlogic g12b (A311D, S922X)
SoC.
- The Gl.Inet mv1000 router based on Marvell Armada 3720
- A Wifi/LTE Dongle based on Qualcomm msm8916
- Two robotics boards based on Qualcomm QRB chips
- Three Snapdragon based phones made by Xiaomi
- Five developments boards based on various Rockchip SoCs, including
the rk3588s-khadas-edge2 and a few NanoPi models
- The AM625 Beagleplay industrial SBC
Another 14 machines get removed: both boards for the obsolete 'oxnas'
platform, three boards for the Renesas r8a77950 SoC that were only for
pre-production chips, and various chromebook models based on the
Qualcomm Sc7180 'trogdor' design that were never part of products"

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timers and timekeeping updates from Thomas Gleixner:
- Improve the VDSO build time checks to cover all dynamic relocations
VDSO does not allow dynamic relocations, but the build time check is
incomplete and fragile.
It's based on architectures specifying the relocation types to search
for and does not handle R_*_NONE relocation entries correctly.
R_*_NONE relocations are injected by some GNU ld variants if they
fail to determine the exact .rel[a]/dyn_size to cover trailing zeros.
R_*_NONE relocations must be ignored by dynamic loaders, so they
should be ignored in the build time check too.
Remove the architecture specific relocation types to check for and
validate strictly that no other relocations than R_*_NONE end up in
the VSDO .so file.
- Prefer signal delivery to the current thread for
CLOCK_PROCESS_CPUTIME_ID based posix-timers
Such timers prefer to deliver the signal to the main thread of a
process even if the context in which the timer expires is the current
task. This has the downside that it might wake up an idle thread.
As there is no requirement or guarantee that the signal has to be
delivered to the main thread, avoid this by preferring the current
task if it is part of the thread group which shares sighand.
This not only avoids waking idle threads, it also distributes the
signal delivery in case of multiple timers firing in the context of
different threads close to each other better.
- Align the tick period properly (again)
For a long time the tick was starting at CLOCK_MONOTONIC zero, which
allowed users space applications to either align with the tick or to
place a periodic computation so that it does not interfere with the
tick. The alignement of the tick period was more by chance than by
intention as the tick is set up before a high resolution clocksource
is installed, i.e. timekeeping is still tick based and the tick
period advances from there.
The early enablement of sched_clock() broke this alignement as the
time accumulated by sched_clock() is taken into account when
timekeeping is initialized. So the base value now(CLOCK_MONOTONIC) is
not longer a multiple of tick periods, which breaks applications
which relied on that behaviour.
Cure this by aligning the tick starting point to the next multiple of
tick periods, i.e 1000ms/CONFIG_HZ.
- A set of NOHZ fixes and enhancements:
* Cure the concurrent writer race for idle and IO sleeptime
statistics
The statitic values which are exposed via /proc/stat are updated
from the CPU local idle exit and remotely by cpufreq, but that
happens without any form of serialization. As a consequence
sleeptimes can be accounted twice or worse.
Prevent this by restricting the accumulation writeback to the CPU
local idle exit and let the remote access compute the accumulated
value.
* Protect idle/iowait sleep time with a sequence count
Reading idle/iowait sleep time, e.g. from /proc/stat, can race
with idle exit updates. As a consequence the readout may result
in random and potentially going backwards values.
Protect this by a sequence count, which fixes the idle time
statistics issue, but cannot fix the iowait time problem because
iowait time accounting races with remote wake ups decrementing
the remote runqueues nr_iowait counter. The latter is impossible
to fix, so the only way to deal with that is to document it
properly and to remove the assertion in the selftest which
triggers occasionally due to that.

- Implement the missing timer_wait_running() callback for POSIX CPU
timers
For unknown reason the introduction of the timer_wait_running()
callback missed to fixup posix CPU timers, which went unnoticed for
almost four years.
While initially only targeted to prevent livelocks between a timer
deletion and the timer expiry function on PREEMPT_RT enabled kernels,
it turned out that fixing this for mainline is not as trivial as just
implementing a stub similar to the hrtimer/timer callbacks.
The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled
systems there is a livelock issue independent of RT.
CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU
timers out from hard interrupt context to task work, which is handled
before returning to user space or to a VM. The expiry mechanism moves
the expired timers to a stack local list head with sighand lock held.
Once sighand is dropped the task can be preempted and a task which
wants to delete a timer will spin-wait until the expiry task is
scheduled back in. In the worst case this will end up in a livelock
when the preempting task and the expiry task are pinned on the same
CPU.
The timer wheel has a timer_wait_running() mechanism for RT, which
uses a per CPU timer-base expiry lock which is held by the expiry
code and the task waiting for the timer function to complete blocks
on that lock.
This does not work in the same way for posix CPU timers as there is
no timer base and expiry for process wide timers can run on any task
belonging to that process, but the concept of waiting on an expiry
lock can be used too in a slightly different way.
Add a per task mutex to struct posix_cputimers_work, let the expiry
task hold it accross the expiry function and let the deleting task
which waits for the expiry to complete block on the mutex.
In the non-contended case this results in an extra
mutex_lock()/unlock() pair on both sides.
This avoids spin-waiting on a task which is scheduled out, prevents
the livelock and cures the problem for RT and !RT systems

====================
Netfilter/IPVS updates for net-next
1) Reduce jumpstack footprint: Stash chain in last rule marker in blob for
tracing. Remove last rule and chain from jumpstack. From Florian Westphal.
2) nf_tables validates all tables before committing the new rules.
Unfortunately, this has two drawbacks:
- Since addition of the transaction mutex pernet state gets written to
outside of the locked section from the cleanup callback, this is
wrong so do this cleanup directly after table has passed all checks.
- Revalidate tables that saw no changes. This can be avoided by
keeping the validation state per table, not per netns.
From Florian Westphal.
3) Get rid of a few redundant pointers in the traceinfo structure.
The three removed pointers are used in the expression evaluation loop,
so gcc keeps them in registers. Passing them to the (inlined) helpers
thus doesn't increase nft_do_chain text size, while stack is reduced
by another 24 bytes on 64bit arches. From Florian Westphal.
4) IPVS cleanups in several ways without implementing any functional
changes, aside from removing some debugging output:
- Update width of source for ip_vs_sync_conn_options
The operation is safe, use an annotation to describe it properly.
- Consistently use array_size() in ip_vs_conn_init()
It seems better to use helpers consistently.
- Remove {Enter,Leave}Function. These seem to be well past their
use-by date.
- Correct spelling in comments.

Pull acl updates from Christian Brauner:
"After finishing the introduction of the new posix acl api last cycle
the generic POSIX ACL xattr handlers are still around in the
filesystems xattr handlers for two reasons:
(1) Because a few filesystems rely on the ->list() method of the
generic POSIX ACL xattr handlers in their ->listxattr() inode
operation.
(2) POSIX ACLs are only available if IOP_XATTR is raised. The
IOP_XATTR flag is raised in inode_init_always() based on whether
the sb->s_xattr pointer is non-NULL. IOW, the registered xattr
handlers of the filesystem are used to raise IOP_XATTR. Removing
the generic POSIX ACL xattr handlers from all filesystems would
risk regressing filesystems that only implement POSIX ACL support
and no other xattrs (nfs3 comes to mind).
This contains the work to decouple POSIX ACLs from the IOP_XATTR flag
as they don't depend on xattr handlers anymore. So it's now possible
to remove the generic POSIX ACL xattr handlers from the sb->s_xattr
list of all filesystems. This is a crucial step as the generic POSIX
ACL xattr handlers aren't used for POSIX ACLs anymore and POSIX ACLs
don't depend on the xattr infrastructure anymore.
Adressing problem (1) will require more long-term work. It would be
best to get rid of the ->list() method of xattr handlers completely at
some point.
For erofs, ext{2,4}, f2fs, jffs2, ocfs2, and reiserfs the nop POSIX
ACL xattr handler is kept around so they can continue to use
array-based xattr handler indexing.
This update does simplify the ->listxattr() implementation of all
these filesystems however"

Pull pidfd updates from Christian Brauner:
"This adds a new pidfd_prepare() helper which allows the caller to
reserve a pidfd number and allocates a new pidfd file that stashes the
provided struct pid.
It should be avoided installing a file descriptor into a task's file
descriptor table just to close it again via close_fd() in case an
error occurs. The fd has been visible to userspace and might already
be in use. Instead, a file descriptor should be reserved but not
installed into the caller's file descriptor table.
If another failure path is hit then the reserved file descriptor and
file can just be put without any userspace visible side-effects. And
if all failure paths are cleared the file descriptor and file can be
installed into the task's file descriptor table.
This helper is now used in all places that open coded this
functionality before. For example, this is currently done during
copy_process() and fanotify used pidfd_create(), which returns a pidfd
that has already been made visibile in the caller's file descriptor
table, but then closed it using close_fd().

Pull user work thread updates from Christian Brauner:
"This contains the work generalizing the ability to create a kernel
worker from a userspace process.
Such user workers will run with the same credentials as the userspace
process they were created from providing stronger security and
accounting guarantees than the traditional override_creds() approach
ever could've hoped for.
The original work was heavily based and optimzed for the needs of
io_uring which was the first user. However, as it quickly turned out
the ability to create user workers inherting properties from a
userspace process is generally useful.
The vhost subsystem currently creates workers using the kthread api.
The consequences of using the kthread api are that RLIMITs don't work
correctly as they are inherited from khtreadd. This leads to bugs
where more workers are created than would be allowed by the RLIMITs of
the userspace process in lieu of which workers are created.
Problems like this disappear with user workers created from the
userspace processes for which they perform the work. In addition,
providing this api allows vhost to remove additional complexity. For
example, cgroup and mm sharing will just work out of the box with user
workers based on the relevant userspace process instead of manually
ensuring the correct cgroup and mm contexts are used.
So the vhost subsystem should simply be made to use the same mechanism
as io_uring. To this end the original mechanism used for
create_io_thread() is generalized into user workers:
- Introduce PF_USER_WORKER as a generic indicator that a given task
is a user worker, i.e., a kernel task that was created from a
userspace process. Now a PF_IO_WORKER thread is just a specialized
version of PF_USER_WORKER. So io_uring io workers raise both flags.
- Make copy_process() available to core kernel code
- Extend struct kernel_clone_args with the following bitfields
allowing to indicate to copy_process():
- to create a user worker (raise PF_USER_WORKER)
- to not inherit any files from the userspace process
- to ignore signals
After all generic changes are in place the vhost subsystem implements
a new dedicated vhost api based on user workers. Finally, vhost is
switched to rely on the new api moving it off of kthreads.

arduous journey"

- Initial renaming of k[v]free_rcu() to k[v]free_rcu_mightsleep() for
increased robustness, affecting several components like mac802154,
drbd, vmw_vmci, tracing, and more.
A report by Eric Dumazet showed that the API could be unknowingly
used in an atomic context, so we'd rather make sure they know what
they're asking for by being explicit:

- Documentation updates, including corrections to spelling,
clarifications in comments, and improvements to the srcu_size_state
comments.
- Better srcu_struct cache locality for readers, by adjusting the size
of srcu_struct in support of SRCU usage by Christoph Hellwig.
- Teach lockdep to detect deadlocks between srcu_read_lock() vs
synchronize_srcu() contributed by Boqun.
Previously lockdep could not detect such deadlocks, now it can.
- Integration of rcutorture and rcu-related tools, targeted for v6.4
from Boqun's tree, featuring new SRCU deadlock scenarios, test_nmis
module parameter, and more
- Miscellaneous changes, various code cleanups and comment improvements

Pull tpm updates from Jarkko Sakkinen:
- The .machine keyring, used for Machine Owner Keys (MOK), acquired the
ability to store only CA enforced keys, and put rest to the .platform
keyring, thus separating the code signing keys from the keys that are
used to sign certificates.
This essentially unlocks the use of the .machine keyring as a trust
anchor for IMA. It is an opt-in feature, meaning that the additional
contraints won't brick anyone who does not care about them.
- Enable interrupt based transactions with discrete TPM chips (tpm_tis).
There was code for this existing but it never really worked so I
consider this a new feature rather than a bug fix. Before the driver
just fell back to the polling mode.

Pull lsm updates from Paul Moore:
- Move the LSM hook comment blocks into security/security.c
For many years the LSM hook comment blocks were located in a very odd
place, include/linux/lsm_hooks.h, where they lived on their own,
disconnected from both the function prototypes and definitions.
In keeping with current kernel conventions, this moves all of these
comment blocks to the top of the function definitions, transforming
them into the kdoc format in the process. This should make it much
easier to maintain these comments, which are the main source of LSM
hook documentation.
For the most part the comment contents were left as-is, although some
glaring errors were corrected. Expect additional edits in the future
as we slowly update and correct the comment blocks.
This is the bulk of the diffstat.
- Introduce LSM_ORDER_LAST
Similar to how LSM_ORDER_FIRST is used to specify LSMs which should
be ordered before "normal" LSMs, the LSM_ORDER_LAST is used to
specify LSMs which should be ordered after "normal" LSMs.
This is one of the prerequisites for transitioning IMA/EVM to a
proper LSM.
- Remove the security_old_inode_init_security() hook
The security_old_inode_init_security() LSM hook only allows for a
single xattr which is problematic both for LSM stacking and the
IMA/EVM-as-a-LSM effort. This finishes the conversion over to the
security_inode_init_security() hook and removes the single-xattr LSM
hook.
- Fix a reiserfs problem with security xattrs
During the security_old_inode_init_security() removal work it became
clear that reiserfs wasn't handling security xattrs properly so we
fixed it.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore:
- Stop passing the 'selinux_state' pointers as function arguments
As discussed during the end of the last development cycle, passing a
selinux_state pointer through the SELinux code has a noticeable
impact on performance, and with the current code it is not strictly
necessary.
This simplifies things by referring directly to the single
selinux_state global variable which should help improve SELinux
performance.
- Uninline the unlikely portions of avc_has_perm_noaudit()
This change was also based on a discussion from the last development
cycle, and is heavily based on an initial proof of concept patch from
you. The core issue was that avc_has_perm_noaudit() was not able to
be inlined, as intended, due to its size. We solved this issue by
extracting the less frequently hit portions of avc_has_perm_noaudit()
into a separate function, reducing the size of avc_has_perm_noaudit()
to the point where the compiler began inlining the function. We also
took the opportunity to clean up some ugly RCU locking in the code
that became uglier with the change.
- Remove the runtime disable functionality
After several years of work by the userspace and distro folks, we are
finally in a place where we feel comfortable removing the runtime
disable functionality which we initially deprecated at the start of
2020.
There is plenty of information in the kernel's deprecation (now
removal) notice, but the main motivation was to be able to safely
mark the LSM hook structures as '__ro_after_init'.
LWN also wrote a good summary of the deprecation this morning which
offers a more detailed history:
https://lwn.net/SubscriberLink/927463/dcfa0d4ed2872f03
- Remove the checkreqprot functionality
The original checkreqprot deprecation notice stated that the removal
would happen no sooner than June 2021, which means this falls hard
into the "better late than never" bucket.
The Kconfig and deprecation notice has more detail on this setting,
but the basic idea is that we want to ensure that the SELinux policy
allows for the memory protections actually applied by the kernel, and
not those requested by the process.
While we haven't found anyone running a supported distro that is
affected by this deprecation/removal, anyone who is affected would
only need to update their policy to reflect the reality of their
applications' mapping protections.
- Minor Makefile improvements
Some minor Makefile improvements to correct some dependency issues
likely only ever seen by SELinux developers. I expect we will have at
least one more tweak to the Makefile during the next merge window,
but it didn't quite make the cutoff this time around.
