KVM/arm64 changes for 6.17, round #1
- Host driver for GICv5, the next generation interrupt controller for
arm64, including support for interrupt routing, MSIs, interrupt
translation and wired interrupts.
- Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
GICv5 hardware, leveraging the legacy VGIC interface.
- Userspace control of the 'nASSGIcap' GICv3 feature, allowing
userspace to disable support for SGIs w/o an active state on hardware
that previously advertised it unconditionally.
- Map supporting endpoints with cacheable memory attributes on systems
with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
maintenance on the address range.
- Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
hypervisor to inject external aborts into an L2 VM and take traps of
masked external aborts to the hypervisor.
- Convert more system register sanitization to the config-driven
implementation.
- Fixes to the visibility of EL2 registers, namely making VGICv3 system
registers accessible through the VGIC device instead of the ONE_REG
vCPU ioctls.
- Various cleanups and minor fixes.

KVM x86 misc changes for 6.17
- Prevert the host's DEBUGCTL.FREEZE_IN_SMM (Intel only) when running the
guest. Failure to honor FREEZE_IN_SMM can bleed host state into the guest.
- Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter (Intel only) to
prevent L1 from running L2 with features that KVM doesn't support, e.g. BTF.
- Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to the
vCPU's CPUID model.
- Rework the MSR interception code so that the SVM and VMX APIs are more or
less identical.
- Recalculate all MSR intercepts from the "source" on MSR filter changes, and
drop the dedicated "shadow" bitmaps (and their awful "max" size defines).
- WARN and reject loading kvm-amd.ko instead of panicking the kernel if the
nested SVM MSRPM offsets tracker can't handle an MSR.
- Advertise support for LKGS (Load Kernel GS base), a new instruction that's
loosely related to FRED, but is supported and enumerated independently.
- Fix a user-triggerable WARN that syzkaller found by stuffing INIT_RECEIVED,
a.k.a. WFS, and then putting the vCPU into VMX Root Mode (post-VMXON). Use
the same approach KVM uses for dealing with "impossible" emulation when
running a !URG guest, and simply wait until KVM_RUN to detect that the vCPU
has architecturally impossible state.
- Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of
APERF/MPERF reads, so that a "properly" configured VM can "virtualize"
APERF/MPERF (with many caveats).
- Reject KVM_SET_TSC_KHZ if vCPUs have been created, as changing the "default"
frequency is unsupported for VMs with a "secure" TSC, and there's no known
use case for changing the default frequency for other VM types.

Pull regulator updates from Mark Brown:
"The big change in this release is the addition of Rust bindings from
Daniel Almeida, allowing fairly basic consumer use with support for
enable and voltage setting operations. This should be good for the
vast majority of consumers.
Otherwise it's been quite quiet, a few new devices supported, plus
some cleanups and fixes.
Summary:
- Basic Rust bindings
- A fix for making large voltage changes on regulators where we limit
the size of voltage change we will do in one step, previously we
just got as close as we could in one step
- Cleanups of our usage of the PM autosuspend functions, this pulls
in some PM core changes on a shared tag
- Mode setting support for PCA9450
- Support for Mediatek MT6893 and MT8196 DVFSRC, Qualcomm PM7550 and
PMR735B, Raspberry Pi displays and TI TPS652G1

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"There's one new driver (Apple SMC) and extensions to existing drivers
for supporting new HW models. A lot of different impovements across
drivers and in core GPIO code. Details on that are in the signed tag
as usual.
We managed to remove some of the legacy APIs. Arnd Bergmann started to
work on making the legacy bits optional so that we may compile them
only for older platforms that still really need them.
Rob Herring has done a lot of work to convert legacy .txt dt-bindings
for GPIO controllers to YAML. There are only a few left now in the
GPIO tree.
A big part of the commits in this PR concern the conversion of GPIO
drivers to using the new line value setter callbacks. This conversion
is now complete treewide (unless I've missed something) and once all
the changes from different trees land in mainline, I'll send you
another PR containing a commit dropping the legacy callbacks from the
tree.
As the quest to pay back technical dept never really ends, we're
starting another set of interface conversions, this time it's about
moving fields specific to only a handful of drivers using the
gpio-mmio helper out of the core gpio_chip structure that every
controller implements and uses. This cycle we introduce a new set of
APIs and convert a few drivers under drivers/gpio/, next cycle we'll
convert remaining modules treewide (in gpio, pinctrl and mfd trees)
and finally remove the old interfaces and move the gpio-mmio fields
into their own structure wrapping gpio_chip.
One last change I should mention here is the rework of the sysfs
interface. In 2016, we introduced the GPIO character device as the
preferred alternative to the sysfs class under /sys/class/gpio. While
it has seen a wide adoption with the help of its user-space
counterpart - libgpiod - there are still users who prefer the
simplicity of sysfs.
As far as the GPIO subsystem is concerned, the problem is not the
existince of the GPIO class as such but rather the fact that it
exposes the global GPIO numbers to the user-space, stopping us from
ever being able to remove the numberspace from the kernel. To that
end, this release we introduced a parallel, limited sysfs interface
that doesn't expose these numbers and only implements a subset of
features that are relevant to the existing users. This is a result of
several discussions over the course of last year and should allow us
to remove the legacy part some time in the future.
Summary:
GPIOLIB core:
- introduce a parallel, limited sysfs user ABI that doesn't expose
the global GPIO numbers to user-space while maintaining backward
compatibility with the end goal of it completely replacing the
existing interface, allowing us to remove it
- remove the legacy devm_gpio_request() routine which has no more
users
- start the process of allowing to compile-out the legacy parts of
the GPIO core for users who don't need it by introducing a new
Kconfig option: GPIOLIB_LEGACY
- don't use global GPIO numbers in debugfs output from the core code
(drivers still do it, the work is ongoing)
- start the process of moving the fields specific to the gpio-mmio
helper out of the core struct gpio_chip into their own structure
that wraps it: create a new header with modern interfaces and
convert several drivers to using it
- remove the platform data structure associated with the gpio-mmio
helper from the kernel after having converted all remaining users
to generic device properties
- remove legacy struct gpio definition as it has no more users
New drivers:
- add the GPIO driver for the Apple System Management Controller
Driver improvements:
- add support for new models to gpio-adp5585, gpio-tps65219 and
gpio-pca953x
- extend the interrupt support in gpio-loongson-64bit
- allow to mark the simulated GPIO lines as invalid in gpio-sim
- convert all remaining GPIO drivers to using the new GPIO value
setter callbacks
- convert gpio-rcar to using simple device power management ops
callbacks
- don't check if current direction of a line is output before setting
the value in gpio-pisosr and ti-fpc202: the GPIO core already
handles that
- also drop unneeded GPIO range checks in drivers, the core already
makes sure we're within bounds when calling driver callbacks
- use dev_fwnode() where applicable across GPIO drivers
- set line value in gpio-zynqmp-modepin and gpio-twl6040 when the
user wants to change direction of the pin to output even though
these drivers don't need to do anything else to actually set the
direction, otherwise a call like gpiod_direction_output(d, 1) will
not result in the line driver high
- remove the reduntant call to pm_runtime_mark_last_busy() from
gpio-arizona
- use lock guards in gpio-cadence and gpio-mxc
- check the return values of regmap functions in gpio-wcd934x and
gpio-tps65912
- use better regmap interfaces in gpio-wcove and gpio-pca953x
- remove dummy GPIO chip callbacks from several drivers in cases
where the GPIO core can already handle their absence
- allow building gpio-palmas as a module
Fixes:
- use correct bit widths (according to the documentation) in
gpio-virtio
Device-tree bindings:
- convert several of the legacy .txt documents for many different
devices to YAML, improving automatic validation
- create a "trivial" GPIO DT schema that covers a wide range of
simple hardware that share a set of basic GPIO properties
- document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
- document a new model for pca95xx
- add and/or remove properties in YAML documents for gpio-rockchip,
fsl,qoriq-gpio, arm,pl061 and gpio-xilinx
Misc:
- some minor refactoring in several places, adding/removing forward
declarations, moving defines to better places, constify the
arguments in some functions, remove duplicate includes, etc.
- documentation updates"

Pull sound updates from Takashi Iwai:
"This includes lots of file shuffling due to HD-audio code
reorganization and many trivial changes, but otherwise there shouldn't
be much surprise from the functionality POV. The PR includes the PM
changes as prerequisite, too. Some highlights below:
Core:
- Performance optimizations in PCM core code
- Refactoring of ASoC Kconfig menus to be hopefully more consistant
and easier to navigate.
- Refactoring of ASoC DAPM code, mainly hiding functionality that
doesn't need to be exposed to drivers
HD-audio reorganization:
- All code are moved under sound/hda with a bit more understandable
tree structure, as well as file renames
- The huge Realtek driver code is split to several parts, a common
helper module with driver modules per probe entry
- HDMI and Cirrus codec drivers also split
ASoC:
- Further work on the generic handling for SoundWire SDCA devices
- Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI
TAS5753
HD-audio and USB-audio:
- TAS2781 driver cleanup and TAS2770 support
- EQ enablement in CA0132 driver
- USB audio quirk code cleanups
Others:
- Cleanups of PM autosuspend call patterns with the update from the
PM tree

Pull power management updates from Rafael Wysocki:
"As is tradition, cpufreq is the part with the largest number of
updates that include core fixes and cleanups as well as updates of
several assorted drivers, but there are also quite a few updates
related to system sleep, mostly focused on asynchronous suspend and

and resume with runtime PM easier.
Runtime PM is also updated to allow some code duplication in drivers
to be eliminated going forward and to work more consistently overall
in some cases.
Apart from that, there are some driver core updates related to PM
domains that should help to address ordering issues with devm_ cleanup
routines relying on PM domains, some assorted devfreq updates
including core fixes and cleanups, tooling updates, and documentation
and MAINTAINERS updates.
Specifics:

Pull selinux updates from Paul Moore:
- Introduce the concept of a SELinux "neveraudit" type which prevents
all auditing of the given type/domain.
Taken by itself, the benefit of marking a SELinux domain with the
"neveraudit" tag is likely not very interesting, especially given the
significant overlap with the "dontaudit" tag.
However, given that the "neveraudit" tag applies to *all* auditing of
the tagged domain, we can do some fairly interesting optimizations
when a SELinux domain is marked as both "permissive" and "dontaudit"
(think of the unconfined_t domain).
While this pull request includes optimized inode permission and
getattr hooks, these optimizations require SELinux policy changes,
therefore the improvements may not be visible on standard downstream
Linux distos for a period of time.
- Continue the deprecation process of /sys/fs/selinux/user.
After removing the associated userspace code in 2020, we marked the
/sys/fs/selinux/user interface as deprecated in Linux v6.13 with
pr_warn() and the usual documention update.
This adds a five second sleep after the pr_warn(), following a
previous deprecation process pattern that has worked well for us in
the past in helping identify any existing users that we haven't yet
reached.
- Add a __GFP_NOWARN flag to our initial hash table allocation.
Fuzzers such a syzbot often attempt abnormally large SELinux policy
loads, which the SELinux code gracefully handles by checking for
allocation failures, but not before the allocator emits a warning
which causes the automated fuzzing to flag this as an error and
report it to the list. While we want to continue to support the work
done by the fuzzing teams, we want to focus on proper issues and not
an error case that is already handled safely. Add a NOWARN flag to
quiet the allocator and prevent syzbot from tripping on this again.
- Remove some unnecessary selinuxfs cleanup code, courtesy of Al.
- Update the SELinux in-kernel documentation with pointers to
additional information.

Pull CRC updates from Eric Biggers:
- Reorganize the architecture-optimized CRC code
It now lives in lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/,
and it is no longer artificially split into separate generic and arch
modules. This allows better inlining and dead code elimination
The generic CRC code is also no longer exported, simplifying the API.
(This mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
which can be found in the "Crypto library updates" pull request)
- Improve crc32c() performance on newer x86_64 CPUs on long messages by
enabling the VPCLMULQDQ optimized code
- Simplify the crypto_shash wrappers for crc32_le() and crc32c()
Register just one shash algorithm for each that uses the (fully
optimized) library functions, instead of unnecessarily providing
direct access to the generic CRC code
- Remove unused and obsolete drivers for hardware CRC engines

Pull vfs iomap updates from Christian Brauner:
- Refactor the iomap writeback code and split the generic and ioend/bio
based writeback code.
There are two methods that define the split between the generic
writeback code, and the implemementation of it, and all knowledge of
ioends and bios now sits below that layer.
- Add fuse iomap support for buffered writes and dirty folio writeback.
This is needed so that granular uptodate and dirty tracking can be
used in fuse when large folios are enabled. This has two big
advantages. For writes, instead of the entire folio needing to be
read into the page cache, only the relevant portions need to be. For
writeback, only the dirty portions need to be written back instead of
the entire folio.

Pull fileattr updates from Christian Brauner:
"This introduces the new file_getattr() and file_setattr() system calls
after lengthy discussions.
Both system calls serve as successors and extensible companions to
the FS_IOC_FSGETXATTR and FS_IOC_FSSETXATTR system calls which have
started to show their age in addition to being named in a way that
makes it easy to conflate them with extended attribute related
operations.
These syscalls allow userspace to set filesystem inode attributes on
special files. One of the usage examples is the XFS quota projects.
XFS has project quotas which could be attached to a directory. All new
inodes in these directories inherit project ID set on parent
directory.
The project is created from userspace by opening and calling
FS_IOC_FSSETXATTR on each inode. This is not possible for special
files such as FIFO, SOCK, BLK etc. Therefore, some inodes are left
with empty project ID. Those inodes then are not shown in the quota
accounting but still exist in the directory. This is not critical but
in the case when special files are created in the directory with
already existing project quota, these new inodes inherit extended
attributes. This creates a mix of special files with and without
attributes. Moreover, special files with attributes don't have a
possibility to become clear or change the attributes. This, in turn,
prevents userspace from re-creating quota project on these existing
files.
In addition, these new system calls allow the implementation of
additional attributes that we couldn't or didn't want to fit into the
legacy ioctls anymore"

Pull mmap_prepare updates from Christian Brauner:
"Last cycle we introduce f_op->mmap_prepare() in c84bf6dd2b83 ("mm:
introduce new .mmap_prepare() file callback").
This is preferred to the existing f_op->mmap() hook as it does require
a VMA to be established yet, thus allowing the mmap logic to invoke
this hook far, far earlier, prior to inserting a VMA into the virtual
address space, or performing any other heavy handed operations.
This allows for much simpler unwinding on error, and for there to be a
single attempt at merging a VMA rather than having to possibly
reattempt a merge based on potentially altered VMA state.
Far more importantly, it prevents inappropriate manipulation of
incompletely initialised VMA state, which is something that has been
the cause of bugs and complexity in the past.
The intent is to gradually deprecate f_op->mmap, and in that vein this
series coverts the majority of file systems to using f_op->mmap_prepare.
Prerequisite steps are taken - firstly ensuring all checks for mmap
capabilities use the file_has_valid_mmap_hooks() helper rather than
directly checking for f_op->mmap (which is now not a valid check) and
secondly updating daxdev_mapping_supported() to not require a VMA
parameter to allow ext4 and xfs to be converted.
Commit bb666b7c2707 ("mm: add mmap_prepare() compatibility layer for
nested file systems") handles the nasty edge-case of nested file
systems like overlayfs, which introduces a compatibility shim to allow
f_op->mmap_prepare() to be invoked from an f_op->mmap() callback.
This allows for nested filesystems to continue to function correctly
with all file systems regardless of which callback is used. Once we
finally convert all file systems, this shim can be removed.
As a result, ecryptfs, fuse, and overlayfs remain unaltered so they
can nest all other file systems.
We additionally do not update resctl - as this requires an update to
remap_pfn_range() (or an alternative to it) which we defer to a later
series, equally we do not update cramfs which needs a mixed mapping
insertion with the same issue, nor do we update procfs, hugetlbfs,
syfs or kernfs all of which require VMAs for internal state and hooks.
We shall return to all of these later"

Pull fallocate updates from Christian Brauner:
"fallocate() currently supports creating preallocated files
efficiently. However, on most filesystems fallocate() will preallocate
blocks in an unwriten state even if FALLOC_FL_ZERO_RANGE is specified.
The extent state must later be converted to a written state when the
user writes data into this range, which can trigger numerous metadata
changes and journal I/O. This may leads to significant write
amplification and performance degradation in synchronous write mode.
At the moment, the only method to avoid this is to create an empty
file and write zero data into it (for example, using 'dd' with a large
block size). However, this method is slow and consumes a considerable
amount of disk bandwidth.
Now that more and more flash-based storage devices are available it is
possible to efficiently write zeros to SSDs using the unmap write
zeroes command if the devices do not write physical zeroes to the
media.
For example, if SCSI SSDs support the UMMAP bit or NVMe SSDs support
the DEAC bit[1], the write zeroes command does not write actual data
to the device, instead, NVMe converts the zeroed range to a
deallocated state, which works fast and consumes almost no disk write
bandwidth.
This series implements the BLK_FEAT_WRITE_ZEROES_UNMAP feature and
BLK_FLAG_WRITE_ZEROES_UNMAP_DISABLED flag for SCSI, NVMe and
device-mapper drivers, and add the FALLOC_FL_WRITE_ZEROES and
STATX_ATTR_WRITE_ZEROES_UNMAP support for ext4 and raw bdev devices.
fallocate() is subsequently extended with the FALLOC_FL_WRITE_ZEROES
flag. FALLOC_FL_WRITE_ZEROES zeroes a specified file range in such a
way that subsequent writes to that range do not require further
changes to the file mapping metadata. This flag is beneficial for
subsequent pure overwriting within this range, as it can save on block
allocation and, consequently, significant metadata changes"

Pull coredump updates from Christian Brauner:
"This contains an extension to the coredump socket and a proper rework
of the coredump code.
- This extends the coredump socket to allow the coredump server to
tell the kernel how to process individual coredumps. This allows
for fine-grained coredump management. Userspace can decide to just
let the kernel write out the coredump, or generate the coredump
itself, or just reject it.
* COREDUMP_KERNEL
The kernel will write the coredump data to the socket.
* COREDUMP_USERSPACE
The kernel will not write coredump data but will indicate to the
parent that a coredump has been generated. This is used when
userspace generates its own coredumps.
* COREDUMP_REJECT
The kernel will skip generating a coredump for this task.
* COREDUMP_WAIT
The kernel will prevent the task from exiting until the coredump
server has shutdown the socket connection.
The flexible coredump socket can be enabled by using the "@@"
prefix instead of the single "@" prefix for the regular coredump
socket:

- Cleanup the coredump code properly while we have to touch it

Pull misc VFS updates from Christian Brauner:
"This contains the usual selections of misc updates for this cycle.
Features:
- Add ext4 IOCB_DONTCACHE support
This refactors the address_space_operations write_begin() and
write_end() callbacks to take const struct kiocb * as their first
argument, allowing IOCB flags such as IOCB_DONTCACHE to propagate
to the filesystem's buffered I/O path.
Ext4 is updated to implement handling of the IOCB_DONTCACHE flag
and advertises support via the FOP_DONTCACHE file operation flag.
Additionally, the i915 driver's shmem write paths are updated to
bypass the legacy write_begin/write_end interface in favor of
directly calling write_iter() with a constructed synchronous kiocb.
Another i915 change replaces a manual write loop with
kernel_write() during GEM shmem object creation.

Pull dentry d_flags updates from Al Viro:
"The current exclusion rules for dentry->d_flags stores are rather
unpleasant. The basic rules are simple:
- stores to dentry->d_flags are OK under dentry->d_lock
- stores to dentry->d_flags are OK in the dentry constructor, before
becomes potentially visible to other threads
Unfortunately, there's a couple of exceptions to that, and that's
where the headache comes from.
The main PITA comes from d_set_d_op(); that primitive sets ->d_op of
dentry and adjusts the flags that correspond to presence of individual
methods. It's very easy to misuse; existing uses _are_ safe, but proof
of correctness is brittle.
Use in __d_alloc() is safe (we are within a constructor), but we might
as well precalculate the initial value of 'd_flags' when we set the
default ->d_op for given superblock and set 'd_flags' directly instead
of messing with that helper.
The reasons why other uses are safe are bloody convoluted; I'm not
going to reproduce it here. See [1] for gory details, if you care. The
critical part is using d_set_d_op() only just prior to
d_splice_alias(), which makes a combination of d_splice_alias() with
setting ->d_op, etc a natural replacement primitive.
Better yet, if we go that way, it's easy to take setting ->d_op and
modifying 'd_flags' under ->d_lock, which eliminates the headache as
far as 'd_flags' exclusion rules are concerned. Other exceptions are
minor and easy to deal with.
What this series does:
- d_set_d_op() is no longer available; instead a new primitive
(d_splice_alias_ops()) is provided, equivalent to combination of
d_set_d_op() and d_splice_alias().
- new field of struct super_block - 's_d_flags'. This sets the
default value of 'd_flags' to be used when allocating dentries on
this filesystem.
- new primitive for setting 's_d_op': set_default_d_op(). This
replaces stores to 's_d_op' at mount time.
All in-tree filesystems converted; out-of-tree ones will get caught
by the compiler ('s_d_op' is renamed, so stores to it will be
caught). 's_d_flags' is set by the same primitive to match the
's_d_op'.
- a lot of filesystems had sb->s_d_op->d_delete equal to
always_delete_dentry; that is equivalent to setting
DCACHE_DONTCACHE in 'd_flags', so such filesystems can bloody well
set that bit in 's_d_flags' and drop 'd_delete()' from
dentry_operations.
In quite a few cases that results in empty dentry_operations, which
means that we can get rid of those.
- kill simple_dentry_operations - not needed anymore
- massage d_alloc_parallel() to get rid of the other exception wrt
'd_flags' stores - we can set DCACHE_PAR_LOOKUP as soon as we
allocate the new dentry; no need to delay that until we commit to
using the sucker.
As the result, 'd_flags' stores are all either under ->d_lock or done
before the dentry becomes visible in any shared data structures"

Pull erofs updates from Gao Xiang:
"We now support metadata compression. It can be useful for embedded use
cases or archiving a large number of small files.
Additionally, readdir performance has been improved by enabling
readahead (note that it was already common practice for ext3/4 non-dx
and f2fs directories). We may consider further improvements later to
align with ext4's s_inode_readahead_blks behavior for slow devices
too.
The remaining commits are minor.
Summary:
- Add support for metadata compression
- Enable readahead for directories to improve readdir performance
- Minor fixes and cleanups"
