block: avoid possible overflow for chunk_sectors check in blk_stack_limits()
In blk_stack_limits(), we check that the t->chunk_sectors value is a multiple of the t->physical_block_size value. However, by finding the chunk_sectors value in bytes, we may overflow the unsigned int which holds chunk_sectors, so change the check to be based on sectors.

block: Improve read ahead size for rotational devices
For a device that does not advertize an optimal I/O size, the function blk_apply_bdi_limits() defaults to an initial setting of the ra_pages field of struct backing_dev_info to VM_READAHEAD_PAGES, that is, 128 KB. This low I/O size value is far from being optimal for hard-disk devices: when reading files from multiple contexts using buffered I/Os, the seek overhead between the small read commands generated to read-ahead multiple files will significantly limit the performance that can be achieved. This fact applies to all ATA devices as ATA does not define an optimal I/O size and the SCSI SAT specification does not define a default value to expose to the host. Modify blk_apply_bdi_limits() to use a device max_sectors limit to calculate the ra_pages field of struct backing_dev_info, when the device is a rotational one (BLK_FEAT_ROTATIONAL feature is set). For a SCSI disk, this defaults to 2560 KB, which significantly improve performance for buffered reads. Using XFS and sequentially reading randomly selected (large) files stored on a SATA HDD, the maximum throughput achieved with 8 readers reading files with 1MB buffered I/Os increases from 122 MB/s to 167 MB/s (+36%). The improvement is even larger when reading files using 128 KB buffered I/Os, with a throughput increasing from 57 MB/s to 165 MB/s (+189%).

pwm: Changes for v6.17-rc1
Apart from the usual mix of new drivers (pwm-argon-fan-hat), adding
support for variants to existing drivers, minor improvements to both
drivers and docs, device tree documenation updates, the noteworthy
changes are:
- A pull of pm-runtime-6.17-rc1 to make it possible to apply
a582469541a3 ("pwm: img: Remove redundant pm_runtime_mark_last_busy()
calls"). Note this updates the base for my tree to 6.16-rc2.
- A hwmon companion driver to pwm-mc33xs2410 living in drivers/hwmon
and acked by Guenter Roeck
- chardev support for PWM devices
This leverages atomic PWM updates to userspace and at the same time
simplifies and accelerates PWM configuration changes.

spi: Updates for v6.17
This release is almost entirely driver work, mostly new drivers with the
usual smattering of per driver updates anf fixes, with only trivial
changes in the core. Highlights include:
- Quite a bit of maintainence work on the STM32 and Qualcomm drivers.
- Usage of the newly added devm_dma_request_chan() in the ateml driver,
pulling in the relevant dmaengine change.
- Cleanups of our usage of the PM autosuspend functions, this pulls in
some PM core changes on a shared tag.
- Support for ADI sigma-delta triggers, Amlogic SPISG, Mediatek MT6991
and MT8196, Renesas RZ/V2H(P) and SOPHGO SG2042.

regulator: Updates for v6.17
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.
- 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.
The TI driver pulls in the MFD portion of the support for the device and
the pinctrl driver which was in the same tag.

gpio updates for v6.17-rc1
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 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:

- introduce a parallel, limited sysfs user ABI that doesn't expose
the global GPIO numbers to user-space while maintaining backward

sound updates for 6.17-rc1
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
- Lots of strcpy() -> strscpy() conversions for fixed size arrays

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
resume of devices and on making the integration of system suspend
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.

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. * tag 'selinux-pr-20250725' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: don't bother with selinuxfs_info_free() on failures selinux: add __GFP_NOWARN to hashtab_init() allocations selinux: optimize selinux_inode_getattr/permission() based on neveraudit|permissive selinux: introduce neveraudit types documentation: add links to SELinux resources selinux: add a 5 second sleep to /sys/fs/selinux/user |

fscrypt updates for 6.17
Simplify how fscrypt uses the crypto API, resulting in some
significant performance improvements:
- Drop the incomplete and problematic support for asynchronous
algorithms. These drivers are bug-prone, and it turns out they are
actually much slower than the CPU-based code as well.
- Allocate crypto requests on the stack instead of the heap. This
improves encryption and decryption performance, especially for
filenames. It also eliminates a point of failure during I/O.

Crypto library tests for 6.17
Add KUnit test suites for the Poly1305, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 library functions. These are the first KUnit tests for lib/crypto/. So in addition to being useful tests for these specific algorithms, they also establish some conventions for lib/crypto/ testing going forwards. The new tests are fairly comprehensive: more comprehensive than the generic crypto infrastructure's tests. They use a variety of techniques to check for the types of implementation bugs that tend to occur in the real world, rather than just naively checking some test vectors. (Interestingly, poly1305_kunit found a bug in QEMU.) The core test logic is shared by all six algorithms, rather than being duplicated for each algorithm. Each algorithm's test suite also optionally includes a benchmark. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCaIZ+WhQcZWJpZ2dlcnNA a2VybmVsLm9yZwAKCRDzXCl4vpKOK+C4AQCOi7iOlFLouUfu9klrovp3i/iSMhyQ gUEHPGSelBy4wQD+NnrLGIdpCcaDAzyWpT4TxG6esN2/97ewh4VUa2MDuQQ= =rS0F -----END PGP SIGNATURE----- Merge tag 'libcrypto-tests-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux Pull crypto library test updates from Eric Biggers: "Add KUnit test suites for the Poly1305, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 library functions.

Crypto library updates for 6.17
This is the main crypto library pull request for 6.17. The main focus
this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
and establishing conventions for lib/crypto/ going forward:
- Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
most of the SHA-512 code) into lib/crypto/. This includes both the
generic and architecture-optimized code. Greatly simplify how the
architecture-optimized code is integrated. Add an easy-to-use
library API for each SHA variant, including HMAC support. Finally,
reimplement the crypto_shash support on top of the library API.
- Apply the same reorganization to the SHA-256 code (and also SHA-224
which shares most of the SHA-256 code). This is a somewhat smaller
change, due to my earlier work on SHA-256. But this brings in all
the same additional improvements that I made for SHA-1 and SHA-512.
There are also some smaller changes:
- Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
these algorithms it's just a move, not a full reorganization yet.
- Fix the MIPS chacha-core.S to build with the clang assembler.
- Fix the Poly1305 functions to work in all contexts.
- Fix a performance regression in the x86_64 Poly1305 code.
- Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
Note that since the new organization of the SHA code is much simpler,
the diffstat of this pull request is negative, despite the addition of
new fully-documented library APIs for multiple SHA and HMAC-SHA
variants. These APIs will allow further simplifications across the
kernel as users start using them instead of the old-school crypto API.
(I've already written a lot of such conversion patches, removing over
1000 more lines of code. But most of those will target 6.18 or later.)

CRC updates for 6.17
Updates for the kernel's CRC (cyclic redundancy check) code:
- 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.
- Remove CRC-32 combination functions that are no longer used.
- Add kerneldoc for crc32_le(), crc32_be(), and crc32c().
- Convert the crc32() macro to an inline function.

ata changes for 6.17-rc1
- Replace the ATA_DFLAG_ZAC device flag with the helper function
ata_dev_is_zac() testing directly the device class and device zoned
mode (me).
- Some small cleanup of ata_scsi_offline_dev() code (me).
- Improve the description of the link power management (LPM) policies
in Kconfig and in the comments defining these. Together with this,
clarify the description of the ahci driver mobile_lpm_policy module
parameter (me).
- Various code refactoring of libata LPM handling (ata_eh_set_lpm()
renaming, introduce ata_dev_config_lpm(), LPM related quirk handling,
and LPM related feature advertizing on device scan) (me).
- Avoid unnecessary device reset when revalidating after an error when
LPM is used (me).
- Do not allow setting a port/link LPM policy if LPM is not supported,
either because the controller does not support partial, slumber nor
devsleep, or when the port is an external port with hotplug
capability (me).
- Make sure that device initiated power management (DIPM) is not
enabled if the host (controller) lacks support for this feature (me).
- Improve messages and debug messages related to LPM, in particular,
reduce the number of messages signaling the lack of LPM support (me).
- Cache in memory a device general purpose log directory to avoid
having to access this log for every log page access. The intent here
is to reduce the number of read log commands when scanning or
revalidating a device (me).
- Change ata_dev_cleanup_cdl_resources() to be a static function (me).
- Rename and simplify the mode setting functions (me).
- Introduce the helper function ata_port_eh_scheduled() to check if EH
is pending or running for a port (me)
- Improve ata_eh_set_pending() (return bool instead of int) (me).
- Use sysfs_emit() instead of scnprintf() for libata-transport
attributes (Jonathan).

- Avoid unnecessary device reset when revalidating after an error when
LPM is used (me)

Clean that up so we can get rid of the need to do that. - Avoid unnecessary memory copies in uring_cmd usage. This is particularly important as a lot of uring_cmd usage necessitates the use of 128b SQEs. - A few updates for recv multishot, where it's now possible to add fairness limits for limiting how much is transferred for each retry loop. Additionally, recv multishot now supports an overall cap as well, where once reached the multishot recv will terminate. The latter is useful for buffer management and juggling many recv streams at the same time. - Add support for returning the TX timestamps via a new socket command. This feature can work in either singleshot or multishot mode, where the latter triggers a completion whenever new timestamps are available. This is an alternative to using the existing error queue. - Add support for an io_uring "mock" file, which is the start of being able to do 100% targeted testing in terms of exercising io_uring request handling.

block: change blk_get_meta_cap() stub return -ENOIOCTLCMD
When introduced in commit 9eb22f7fedfc ("fs: add ioctl to query metadata
and protection info capabilities") the stub of blk_get_meta_cap() for
!BLK_DEV_INTEGRITY always returns -EOPNOTSUPP. The motivation was that
while the command was unsupported in that configuration it was still
recognized.
A later change instead assumed -ENOIOCTLCMD as is required for unknown
ioctl commands per Documentation/driver-api/ioctl.rst. The result being
that on !BLK_DEV_INTEGRITY configs, any ioctl which reaches
blkdev_common_ioctl() will return -EOPNOTSUPP.
Change the stub to return -ENOIOCTLCMD, fixing the issue and better
matching with expectations.
[ The blkdev_common_ioctl() confusion has been fixed, but -ENOIOCTLCMD
is the right thing to return for unrecognized ioctls, so the patch
remains the right thing to do. - Linus ]

fuse: remove page alignment check for writeback len
Remove incorrect page alignment check for the writeback len arg in
fuse_iomap_writeback_range(). len will always be block-aligned as
passed in by iomap.
On regular fuse filesystems, i_blkbits is set to PAGE_SHIFT so this is
not a problem but for fuseblk filesystems, the block size is set to a
default of 512 bytes or a block size passed in at mount time.
Please note that non-page-aligned lengths are fine for the logic in
fuse_iomap_writeback_range(). The check was originally added as a
safeguard to detect conspicuously wrong ranges.

the involved filesystem.
But it will no longer be the case, as multi-device filesystems like
btrfs can handle certain device loss without the need to shutdown the
whole filesystem.
To allow those multi-device filesystems to be integrated to use
fs_holder_ops:
- Add a new super_operations::remove_bdev() callback
- Try ->remove_bdev() callback first inside fs_bdev_mark_dead().
If the callback returned 0, meaning the fs can handling the device
loss, then exit without doing anything else.
If there is no such callback or the callback returned non-zero
value, continue to shutdown the filesystem as usual.
This means the new remove_bdev() should only do the check on whether
the operation can continue, and if so do the fs specific handlings.
The shutdown handling should still be handled by the existing
->shutdown() callback.
For all existing filesystems with shutdown callback, there is no
change to the code nor behavior.
Btrfs is going to implement both the ->remove_bdev() and ->shutdown()
callbacks soon"

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.

Pull pidfs updates from Christian Brauner:
- persistent info
Persist exit and coredump information independent of whether anyone
currently holds a pidfd for the struct pid.
The current scheme allocated pidfs dentries on-demand repeatedly.
This scheme is reaching it's limits as it makes it impossible to pin
information that needs to be available after the task has exited or
coredumped and that should not be lost simply because the pidfd got
closed temporarily. The next opener should still see the stashed
information.
This is also a prerequisite for supporting extended attributes on
pidfds to allow attaching meta information to them.
If someone opens a pidfd for a struct pid a pidfs dentry is allocated
and stashed in pid->stashed. Once the last pidfd for the struct pid
is closed the pidfs dentry is released and removed from pid->stashed.
So if 10 callers create a pidfs dentry for the same struct pid
sequentially, i.e., each closing the pidfd before the other creates a
new one then a new pidfs dentry is allocated every time.
Because multiple tasks acquiring and releasing a pidfd for the same
struct pid can race with each another a task may still find a valid
pidfs entry from the previous task in pid->stashed and reuse it. Or
it might find a dead dentry in there and fail to reuse it and so
stashes a new pidfs dentry. Multiple tasks may race to stash a new
pidfs dentry but only one will succeed, the other ones will put their
dentry.
The current scheme aims to ensure that a pidfs dentry for a struct
pid can only be created if the task is still alive or if a pidfs
dentry already existed before the task was reaped and so exit
information has been was stashed in the pidfs inode.
That's great except that it's buggy. If a pidfs dentry is stashed in
pid->stashed after pidfs_exit() but before __unhash_process() is
called we will return a pidfd for a reaped task without exit
information being available.
The pidfds_pid_valid() check does not guard against this race as it
doens't sync at all with pidfs_exit(). The pid_has_task() check might
be successful simply because we're before __unhash_process() but
after pidfs_exit().
Introduce a new scheme where the lifetime of information associated
with a pidfs entry (coredump and exit information) isn't bound to the
lifetime of the pidfs inode but the struct pid itself.
The first time a pidfs dentry is allocated for a struct pid a struct
pidfs_attr will be allocated which will be used to store exit and
coredump information.
If all pidfs for the pidfs dentry are closed the dentry and inode can
be cleaned up but the struct pidfs_attr will stick until the struct
pid itself is freed. This will ensure minimal memory usage while
persisting relevant information.
The new scheme has various advantages. First, it allows to close the
race where we end up handing out a pidfd for a reaped task for which
no exit information is available. Second, it minimizes memory usage.
Third, it allows to remove complex lifetime tracking via dentries
when registering a struct pid with pidfs. There's no need to get or
put a reference. Instead, the lifetime of exit and coredump
information associated with a struct pid is bound to the lifetime of
struct pid itself.
- extended attributes
Now that we have a way to persist information for pidfs dentries we
can start supporting extended attributes on pidfds. This will allow
userspace to attach meta information to tasks.
One natural extension would be to introduce a custom pidfs.* extended
attribute space and allow for the inheritance of extended attributes
across fork() and exec().
The first simple scheme will allow privileged userspace to set
trusted extended attributes on pidfs inodes.
- Allow autonomous pidfs file handles
Various filesystems such as pidfs and drm support opening file
handles without having to require a file descriptor to identify the
filesystem. The filesystem are global single instances and can be
trivially identified solely on the information encoded in the file
handle.
This makes it possible to not have to keep or acquire a sentinal file
descriptor just to pass it to open_by_handle_at() to identify the
filesystem. That's especially useful when such sentinel file
descriptor cannot or should not be acquired.
For pidfs this means a file handle can function as full replacement
for storing a pid in a file. Instead a file handle can be stored and
reopened purely based on the file handle.
Such autonomous file handles can be opened with or without specifying
a a file descriptor. If no proper file descriptor is used the
FD_PIDFS_ROOT sentinel must be passed. This allows us to define
further special negative fd sentinels in the future.
Userspace can trivially test for support by trying to open the file
handle with an invalid file descriptor.
- Allow pidfds for reaped tasks with SCM_PIDFD messages
This is a logical continuation of the earlier work to create pidfds
for reaped tasks through the SO_PEERPIDFD socket option merged in
923ea4d4482b ("Merge patch series "net, pidfs: enable handing out
pidfds for reaped sk->sk_peer_pid"").

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"

to identify the initial namespaces. That's already a hard

that currently don't do that with all the other namespaces.
- The root inode of /proc having a fixed inode number has been part
of the core kernel ABI since its inception, and recently some
userspace programs (mainly container runtimes) have started to
explicitly depend on this behaviour.
The main reason this is useful to userspace is that by checking
that a suspect /proc handle has fstype PROC_SUPER_MAGIC and is
PROCFS_ROOT_INO, they can then use openat2() together with
RESOLVE_{NO_{XDEV,MAGICLINK},BENEATH} to ensure that there isn't a

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:
@@/run/systemd/coredump.socket
- Cleanup the coredump code properly while we have to touch it
anyway.
Split out each coredump mode in a separate helper so it's easy to
grasp what is going on and make the code easier to follow. The core
coredump function should now be very trivial to follow"

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.
Cleanups:
- don't duplicate vfs_open() in kernel_file_open()
- proc_fd_getattr(): don't bother with S_ISDIR() check
- fs/ecryptfs: replace snprintf with sysfs_emit in show function
- vfs: Remove unnecessary list_for_each_entry_safe() from
evict_inodes()
- filelock: add new locks_wake_up_waiter() helper
- fs: Remove three arguments from block_write_end()
- VFS: change old_dir and new_dir in struct renamedata to dentrys
- netfs: Remove unused declaration netfs_queue_write_request()
Fixes:
- eventpoll: Fix semi-unbounded recursion
- eventpoll: fix sphinx documentation build warning
- fs/read_write: Fix spelling typo
- fs: annotate data race between poll_schedule_timeout() and
pollwake()
- fs/pipe: set FMODE_NOWAIT in create_pipe_files()
- docs/vfs: update references to i_mutex to i_rwsem
- fs/buffer: remove comment about hard sectorsize
- fs/buffer: remove the min and max limit checks in __getblk_slow()
- fs/libfs: don't assume blocksize <= PAGE_SIZE in
generic_check_addressable
- fs_context: fix parameter name in infofc() macro
- fs: Prevent file descriptor table allocations exceeding INT_MAX"

mount changes. I've got more stuff in the local tree, but
this is getting too much for one merge window as it is.
* mount hash conflicts rudiments are gone now - we do not allow
multiple mounts with the same parent/mountpoint to be
hashed at the same time.
* struct mount changes
mnt_umounting is gone;
mnt_slave_list/mnt_slave is an hlist now;
overmounts are kept track of by explicit pointer in mount;
a bunch of flags moved out of mnt_flags to a new field,
with only namespace_sem for protection;
mnt_expiry is protected by mount_lock now (instead of
namespace_sem);
MNT_LOCKED is used only for mounts that need to remain
attached to their parents to prevent mountpoint exposure -
no more overloading it for absolute roots;
all mnt_list uses are transient now - it's used only to
represent temporary sets during umount_tree().
* mount refcounting change
children no longer pin parents for any mounts, whether they'd
passed through umount_tree() or not.
* struct mountpoint changes
refcount is no more; what matters is ->m_list emptiness;
instead of temporary bumping the refcount, we insert a new object
(pinned_mountpoint) into ->m_list;
new calling conventions for lock_mount() and friends.
* do_move_mount()/attach_recursive_mnt() seriously cleaned up.
* globals in fs/pnode.c are gone.
* propagate_mnt(), change_mnt_propagation() and propagate_umount() cleaned up
(in the last case - pretty much completely rewritten).
* freeing of emptied mnt_namespace is done in namespace_unlock()
for one thing, there are subtle ordering requirements there;
for another it simplifies cleanups.
* assorted cleanups.
* restore the machinery for long-term mounts from accumulated bitrot.
This is going to get a followup come next cycle, when #work.fs_context
with its change of vfs_fs_parse_string() calling conventions goes
into -next.
