Pull networking updates from Paolo Abeni:
 "The most significant set of changes is the per netns RTNL. The new
  behavior is disabled by default, regression risk should be contained.

  Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
  default value from PTP_1588_CLOCK_KVM, as the first is intended to be
  a more reliable replacement for the latter.

  Core:

   - Started a very large, in-progress, effort to make the RTNL lock
     scope per network-namespace, thus reducing the lock contention
     significantly in the containerized use-case, comprising:
       - RCU-ified some relevant slices of the FIB control path
       - introduce basic per netns locking helpers
       - namespacified the IPv4 address hash table
       - remove rtnl_register{,_module}() in favour of
         rtnl_register_many()
       - refactor rtnl_{new,del,set}link() moving as much validation as
         possible out of RTNL lock
       - convert all phonet doit() and dumpit() handlers to RCU
       - convert IPv4 addresses manipulation to per-netns RTNL
       - convert virtual interface creation to per-netns RTNL
     the per-netns lock infrastructure is guarded by the
     CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.

   - Introduce NAPI suspension, to efficiently switching between busy
     polling (NAPI processing suspended) and normal processing.

   - Migrate the IPv4 routing input, output and control path from direct
     ToS usage to DSCP macros. This is a work in progress to make ECN
     handling consistent and reliable.

   - Add drop reasons support to the IPv4 rotue input path, allowing
     better introspection in case of packets drop.

   - Make FIB seqnum lockless, dropping RTNL protection for read access.

   - Make inet{,v6} addresses hashing less predicable.

   - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
     and timestamps

  Things we sprinkled into general kernel code:

   - Add small file operations for debugfs, to reduce the struct ops
     size.

   - Refactoring and optimization for the implementation of page_frag
     API, This is a preparatory work to consolidate the page_frag
     implementation.

  Netfilter:

   - Optimize set element transactions to reduce memory consumption

   - Extended netlink error reporting for attribute parser failure.

   - Make legacy xtables configs user selectable, giving users the
     option to configure iptables without enabling any other config.

   - Address a lot of false-positive RCU issues, pointed by recent CI
     improvements.

  BPF:

   - Put xsk sockets on a struct diet and add various cleanups. Overall,
     this helps to bump performance by 12% for some workloads.

   - Extend BPF selftests to increase coverage of XDP features in
     combination with BPF cpumap.

   - Optimize and homogenize bpf_csum_diff helper for all archs and also
     add a batch of new BPF selftests for it.

   - Extend netkit with an option to delegate skb->{mark,priority}
     scrubbing to its BPF program.

   - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
     programs.

  Protocols:

   - Introduces 4-tuple hash for connected udp sockets, speeding-up
     significantly connected sockets lookup.

   - Add a fastpath for some TCP timers that usually expires after
     close, the socket lock contention.

   - Add inbound and outbound xfrm state caches to speed up state
     lookups.

   - Avoid sending MPTCP advertisements on stale subflows, reducing
     risks on loosing them.

   - Make neighbours table flushing more scalable, maintaining per
     device neigh lists.

  Driver API:

   - Introduce a unified interface to configure transmission H/W
     shaping, and expose it to user-space via generic-netlink.

   - Add support for per-NAPI config via netlink. This makes napi
     configuration persistent across queues removal and re-creation.
     Requires driver updates, currently supported drivers are:
     nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.

   - Add ethtool support for writing SFP / PHY firmware blocks.

   - Track RSS context allocation from ethtool core.

   - Implement support for mirroring to DSA CPU port, via TC mirror
     offload.

   - Consolidate FDB updates notification, to avoid duplicates on
     device-specific entries.

   - Expose DPLL clock quality level to the user-space.

   - Support master-slave PHY config via device tree.

  Tests and tooling:

   - forwarding: introduce deferred commands, to simplify the cleanup
     phase

  Drivers:

   - Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
     Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
     IRQs and queues to NAPI IDs, allowing busy polling and better
     introspection.

Pull SoC driver updates from Arnd Bergmann:
 "Nothing particular important in the SoC driver updates, just the usual
  improvements to for drivers/soc and a couple of subsystems that don't
  fit anywhere else:

   - The largest set of updates is for Qualcomm SoC drivers, extending
     the set of supported features for additional SoCs in the QSEECOM,
     LLCC and socinfo drivers.a

   - The ti_sci firmware driver gains support for power managment

   - The drivers/reset subsystem sees a rework of the microchip sparx5
     and amlogic reset drivers to support additional chips, plus a few
     minor updates on other platforms

   - The SCMI firmware interface driver gains support for two protocol
     extensions, allowing more flexible use of the shared memory area
     and new DT binding properties for configurability.

   - Mediatek SoC drivers gain support for power managment on the MT8188
     SoC and a new driver for DVFS.

   - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
     and a few bugfixes

   - The Hisilicon Kunpeng HCCS driver gains support for configuring
     lanes through sysfs

  Finally, there are cleanups and minor fixes for drivers/{soc, bus,
  memory}, including changing back the .remove_new callback to .remove,
  as well as a few other updates for freescale (powerpc) soc drivers,
  NXP i.MX soc drivers, cznic turris platform driver, memory controller
  drviers, TI OMAP SoC drivers, and Tegra firmware drivers"

Pull SoC devicetree updates from Arnd Bergmann:
 "This release adds the devicetree files for an impressive number of new
  SoC variants, though as expected these are all related to others we
  already support:

   - The microchip sam9x7 devicetree is now added, after the device
     driver and platform code has already made it in. This is likely the
     last ARMv5 (!) platform to ever get added, updating the 20+ year
     old at91/sam9 platform with DDR3 memory and gigabit ethernet.

   - On the Apple platform, there are now devicetree files for a number
     of A-series SoCs in addition to the M-series ones, these are used
     primarily in phones and tablets, but are closely related to the
     already supported chips.

   - Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in
     older Samsung Galaxy phones.

   - Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely
     related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end
     laptops.

   - Rockchip RK3528 and RK3576 are new variants of their TV box and
     Tablet chips, still using the older ARMv8.0 cores from
     RK3328/RK3399 but with a newer process and other improvements from
     the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also
     added, these are just lower-cost versions of their normal
     counterparts.

   - TI J742S2 is a feature-reduced version of the J784s4
     industrial/automotive SoC, with fewer CPU cores.

   - Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
     (Cortex-A53) core, at this point support is only added for running
     on the RISC-V side on the LicheeRV Nano board.

  A total of 92 new .dts files describing individual machines is added,
  which must be a new record. The majority of these is for the newly
  added chips above, notably all the Apple phones and tablets. The other
  new machines include nine industrial/embedded boards with NXP i.MX6 or
  i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for
  Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm
  qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.

  As usual there are also many newly added features in existing boards
  as well as cleanups and minor bugfixes"

131561f2ca Merge tag 'gpio-updates-for-v6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
 "Three new drivers, support for some new models in existing ones and
  lots of various tweaks and improvements across the board (switching to
  using recommended APIs, code shrink and simplification, etc.).

  Also a new feature in the character device uAPI where we now notify
  the user-space about changes triggered by in-kernel users as well, not
  only when they were done by other user-space agents.

  Summary:

  GPIOLIB core:
   - use the new mem_is_zero() instead of memchr_inv(s, 0, n)
   - don't store debounce period twice needlessly
   - clean-up debugfs handling
   - remove leftover comments referring to no longer used spinlocks
   - unduplicate some operations like SRCU locks and initializing GPIO
     descriptors
   - constify the sysfs class struct
   - use lock guards in GPIO sysfs code
   - update GPIO uAPI internal flags all at once atomically for
     consistency with other places
   - modify the behavior of the sysfs interface by no longer exporting
     lines that are named inside the driver code or board files with the
     sysfs links bearing the line names as this has for many years been
     largely unused due to the prevalence of DT, ACPI and firmware nodes
     over board files and made the API inconsistent
   - for GPIO interrupt providers: free irqs that are still requested by
     users when removing the chip

  GPIO uAPI:
   - notify user-space about changes to GPIO lines' state (requested,
     released, reconfigured) triggered from the kernel as well (until
     now we'd only do this for changes triggered from user-space)
   - to that end: modify the internal workings of the notification
     mechanism by switching to an atomic notifier which allows us to
     send events from atomic context
   - also to that end store the debounce period in the GPIO descriptor
     struct and not in the character device context struct
   - while at it, also cover the corner-case of users introducing
     changes over sysfs while others watch them via the character device
   - don't report GPIO lines requested as interrupts as "used" to
     user-space as it can still request them as GPIOs

  New drivers:
   - GPIO part of the MFD Congatec Board Controller
   - PolarFire GPIO controller
   - GPIOs on FTDI FT2232H

  Driver improvements:
   - use generic device property accessors instead of OF-specific ones
     across many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci,
     ts4900, xilinx, mvebu)
   - use devres helpers to simplify error paths and either shrink or
     entirely remove the driver's remove() callback (grgpio, amdpt,
     menz127, max730x, ftgpio010, 74x164, ljca)
   - use helper variables to store the address of pdev->dev and avoid
     some line-breaks
   - use device_for_each_child_node_scoped() to avoid having to put the
     fwnode on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
   - use a scoped bitmap to simplify the code and drop goto labels in
     gpio-aggregator
   - drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby,
     xilinx)
   - add support for new models to gpio-aspeed, gpio-rockchip and
     gpio-dwapb
   - clean-up ACPI handling and some other bits in gpio-xgene-sb
   - replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
   - allow to build davinci and mvebu drivers with COMPILE_TEST=y
   - remove dead code in gpio-mb86s7x
   - switch back to using platform_driver::remove() (after the
     conversion to remove_new()) across the GPIO drivers
   - remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop
     this deprecated symbol
   - convert the gpio-altera driver to no longer pull in the deprecated
     legacy-of-mm-gpiochip.h header
   - use of_property_present() instead of of_property_read_bool() in
     gpiolib-of and gpio-rockchip
   - allow to build the tegra186 driver on Tegra234 platforms in Kconfig

  Late fixes:
   - add a missing return value check after devm_kasprintf() to
     gpio-grgpio

  DT bindings:
   - document the ngpios property of gpio-mmio
   - add support for a new aspeed model
   - fix the example for st,nomadik-gpio

  Other:
   - kernel doc and comments tweaks
   - fix typos in TODO
   - reorder headers alphabetically in some drivers
   - fix incorrect format specifiers in gpio tools"

 "This contains a new abstraction for PWM waveforms that is more
  expressive that the legacy one. Compared to the old abstraction it

  The new API requires changes to the lowlevel drivers. For now there
  are two drivers that are converted to the new API (axi-pwmgen and
  stm32). Converted drivers continue to work with the old API. Drivers
  not yet converted only work with the older API.

Pull sched_ext updates from Tejun Heo:

 - Improve the default select_cpu() implementation making it topology
   aware and handle WAKE_SYNC better.

 - set_arg_maybe_null() was used to inform the verifier which ops args
   could be NULL in a rather hackish way. Use the new __nullable CFI
   stub tags instead.

 - On Sapphire Rapids multi-socket systems, a BPF scheduler, by
   hammering on the same queue across sockets, could live-lock the
   system to the point where the system couldn't make reasonable forward
   progress.

   This could lead to soft-lockup triggered resets or stalling out
   bypass mode switch and thus BPF scheduler ejection for tens of
   minutes if not hours. After trying a number of mitigations, the
   following set worked reliably:

     - Injecting artificial cpu_relax() loops in two places while
       sched_ext is trying to turn on the bypass mode.

     - Triggering scheduler ejection when soft-lockup detection is
       imminent (a quarter of threshold left).

   While not the prettiest, the impact both in terms of code complexity
   and overhead is minimal.

 - A common complaint on the API is the overuse of the word "dispatch"
   and the confusion around "consume". This is due to how the dispatch
   queues became more generic over time. Rename the affected kfuncs for
   clarity. Thanks to BPF's compatibility features, this change can be
   made in a way that's both forward and backward compatible. The
   compatibility code will be dropped in a few releases.

Pull workqueue updates from Tejun Heo:

 - The maximum concurrency limit of 512 which was set a long time ago is
   too low now.

   A legitimate use (BPF cgroup release) of system_wq could saturate it
   under stress test conditions leading to false dependencies and
   deadlocks.

   While the offending use was switched to a dedicated workqueue, use
   the opportunity to bump WQ_MAX_ACTIVE four fold and document that
   system workqueue shouldn't be saturated. Workqueue should add at
   least a warning mechanism for cases where system workqueues are
   saturated.

 - Recent workqueue updates to support more flexible execution topology
   made unbound workqueues use per-cpu worker pool frontends which
   pushed up workqueue flush overhead.

   As consecutive CPUs are likely to be pointing to the same worker
   pool, reduce overhead by switching locks only when necessary.

Pull timer updates from Thomas Gleixner:
 "A rather large update for timekeeping and timers:

   - The final step to get rid of auto-rearming posix-timers

     posix-timers are currently auto-rearmed by the kernel when the
     signal of the timer is ignored so that the timer signal can be
     delivered once the corresponding signal is unignored.

     This requires to throttle the timer to prevent a DoS by small
     intervals and keeps the system pointlessly out of low power states
     for no value. This is a long standing non-trivial problem due to
     the lock order of posix-timer lock and the sighand lock along with
     life time issues as the timer and the sigqueue have different life
     time rules.

     Cure this by:

       - Embedding the sigqueue into the timer struct to have the same
         life time rules. Aside of that this also avoids the lookup of
         the timer in the signal delivery and rearm path as it's just a
         always valid container_of() now.

       - Queuing ignored timer signals onto a seperate ignored list.

       - Moving queued timer signals onto the ignored list when the
         signal is switched to SIG_IGN before it could be delivered.

       - Walking the ignored list when SIG_IGN is lifted and requeue the
         signals to the actual signal lists. This allows the signal
         delivery code to rearm the timer.

     This also required to consolidate the signal delivery rules so they
     are consistent across all situations. With that all self test
     scenarios finally succeed.

   - Core infrastructure for VFS multigrain timestamping

     This is required to allow the kernel to use coarse grained time
     stamps by default and switch to fine grained time stamps when inode
     attributes are actively observed via getattr().

     These changes have been provided to the VFS tree as well, so that
     the VFS specific infrastructure could be built on top.

   - Cleanup and consolidation of the sleep() infrastructure

       - Move all sleep and timeout functions into one file

       - Rework udelay() and ndelay() into proper documented inline
         functions and replace the hardcoded magic numbers by proper
         defines.

       - Rework the fsleep() implementation to take the reality of the
         timer wheel granularity on different HZ values into account.
         Right now the boundaries are hard coded time ranges which fail
         to provide the requested accuracy on different HZ settings.

       - Update documentation for all sleep/timeout related functions
         and fix up stale documentation links all over the place

       - Fixup a few usage sites

   - Rework of timekeeping and adjtimex(2) to prepare for multiple PTP
     clocks

     A system can have multiple PTP clocks which are participating in
     seperate and independent PTP clock domains. So far the kernel only
     considers the PTP clock which is based on CLOCK TAI relevant as
     that's the clock which drives the timekeeping adjustments via the
     various user space daemons through adjtimex(2).

     The non TAI based clock domains are accessible via the file
     descriptor based posix clocks, but their usability is very limited.
     They can't be accessed fast as they always go all the way out to
     the hardware and they cannot be utilized in the kernel itself.

     As Time Sensitive Networking (TSN) gains traction it is required to
     provide fast user and kernel space access to these clocks.

     The approach taken is to utilize the timekeeping and adjtimex(2)
     infrastructure to provide this access in a similar way how the
     kernel provides access to clock MONOTONIC, REALTIME etc.

     Instead of creating a duplicated infrastructure this rework
     converts timekeeping and adjtimex(2) into generic functionality
     which operates on pointers to data structures instead of using
     static variables.

     This allows to provide time accessors and adjtimex(2) functionality
     for the independent PTP clocks in a subsequent step.

   - Consolidate hrtimer initialization

     hrtimers are set up by initializing the data structure and then
     seperately setting the callback function for historical reasons.

     That's an extra unnecessary step and makes Rust support less
     straight forward than it should be.

     Provide a new set of hrtimer_setup*() functions and convert the
     core code and a few usage sites of the less frequently used
     interfaces over.

     The bulk of the htimer_init() to hrtimer_setup() conversion is
     already prepared and scheduled for the next merge window.

   - Drivers:

       - Ensure that the global timekeeping clocksource is utilizing the
         cluster 0 timer on MIPS multi-cluster systems.

         Otherwise CPUs on different clusters use their cluster specific
         clocksource which is not guaranteed to be synchronized with
         other clusters.

       - Mostly boring cleanups, fixes, improvements and code movement"

Pull interrupt subsystem updates from Thomas Gleixner:
 "Tree wide:

   - Make nr_irqs static to the core code and provide accessor functions
     to remove existing and prevent future aliasing problems with local
     variables or function arguments of the same name.

  Core code:

   - Prevent freeing an interrupt in the devres code which is not
     managed by devres in the first place.

   - Use seq_put_decimal_ull_width() for decimal values output in
     /proc/interrupts which increases performance significantly as it
     avoids parsing the format strings over and over.

   - Optimize raising the timer and hrtimer soft interrupts by using the
     'set bit only' variants instead of the combined version which
     checks whether ksoftirqd should be woken up. The latter is a
     pointless exercise as both soft interrupts are raised in the
     context of the timer interrupt and therefore never wake up
     ksoftirqd.

   - Delegate timer/hrtimer soft interrupt processing to a dedicated
     thread on RT.

     Timer and hrtimer soft interrupts are always processed in ksoftirqd
     on RT enabled kernels. This can lead to high latencies when other
     soft interrupts are delegated to ksoftirqd as well.

     The separate thread allows to run them seperately under a RT
     scheduling policy to reduce the latency overhead.

  Drivers:

   - New drivers or extensions of existing drivers to support Renesas
     RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt
     chips

   - Support for multi-cluster GICs on MIPS.

     MIPS CPUs can come with multiple CPU clusters, where each CPU
     cluster has its own GIC (Generic Interrupt Controller). This
     requires to access the GIC of a remote cluster through a redirect
     register block.

     This is encapsulated into a set of helper functions to keep the
     complexity out of the actual code paths which handle the GIC
     details.

   - Support for encrypted guests in the ARM GICV3 ITS driver

     The ITS page needs to be shared with the hypervisor and therefore
     must be decrypted.

   - Small cleanups and fixes all over the place"

 "SRCU:

   - Introduction of the new SRCU-lite flavour with a new pair of

     LOCK and a full memory barrier on UNLOCK. This comes at the expense
     of a higher latency write side with two (in the best case of a
     snaphot of unused read-sides) or more RCU grace periods on the
     update side which now assumes by itself the whole full ordering
     guarantee against the LOCK/UNLOCK counters on both indexes, along
     with the accesses performed inside.

     Uretprobes is a known potential user.

   - Allow short-circuiting RCU-TASKS-RUDE grace periods on
     architectures that have sane noinstr boundaries forbidding tracing
     on low-level idle and kernel entry code. RCU-TASKS is enough on
     such configurations because it involves an RCU grace period that
     waits for all idle tasks to either schedule out voluntarily or
     enter into RCU unwatched noinstr code.

 - Support for running Linux in a protected VM under the Arm
   Confidential Compute Architecture (CCA)

 - Guarded Control Stack user-space support. Current patches follow the
   x86 ABI of implicitly creating a shadow stack on clone(). Subsequent
   patches (already on the list) will add support for clone3() allowing
   finer-grained control of the shadow stack size and placement from
   libc

 - AT_HWCAP3 support (not running out of HWCAP2 bits yet but we are
   getting close with the upcoming dpISA support)

 - Other arch features:

     - In-kernel use of the memcpy instructions, FEAT_MOPS (previously
       only exposed to user; uaccess support not merged yet)

     - MTE: hugetlbfs support and the corresponding kselftests

     - Optimise CRC32 using the PMULL instructions

     - Support for FEAT_HAFT enabling ARCH_HAS_NONLEAF_PMD_YOUNG

     - Optimise the kernel TLB flushing to use the range operations

       reorganise arch_make_huge_pte() and clean up pte_mkcont(), sanity
       check addresses before runtime P4D/PUD folding

     - Command line override for ID_AA64MMFR0_EL1.ECV (advertising the

0338cd9c22 Merge tag 's390-6.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:

 - Add firmware sysfs interface which allows user space to retrieve the
   dump area size of the machine

 - Add 'measurement_chars_full' CHPID sysfs attribute to make the
   complete associated Channel-Measurements Characteristics Block
   available

 - Add virtio-mem support

 - Move gmap aka KVM page fault handling from the main fault handler to
   KVM code. This is the first step to make s390 KVM page fault handling
   similar to other architectures. With this first step the main fault
   handler does not have any special handling anymore, and therefore
   convert it to support LOCK_MM_AND_FIND_VMA

 - With gcc 14 s390 support for flag output operand support for inline
   assemblies was added. This allows for several optimizations:

     - Provide a cmpxchg inline assembly which makes use of this, and
       provide all variants of arch_try_cmpxchg() so that the compiler
       can generate slightly better code

     - Convert a few cmpxchg() loops to try_cmpxchg() loops

     - Similar to x86 add a CC_OUT() helper macro (and other macros),
       and convert all inline assemblies to make use of them, so that
       depending on compiler version better code can be generated

 - List installed host-key hashes in sysfs if the machine supports the
   Query Ultravisor Keys UVC

 - Add 'Retrieve Secret' ioctl which allows user space in protected
   execution guests to retrieve previously stored secrets from the
   Ultravisor

 - Add pkey-uv module which supports the conversion of Ultravisor
   retrievable secrets to protected keys

 - Extend the existing paes cipher to exploit the full AES-XTS hardware
   acceleration introduced with message-security assist extension 10

 - Convert hopefully all sysfs show functions to use sysfs_emit() so
   that the constant flow of such patches stop

 - For PCI devices make use of the newly added Topology ID attribute to
   enable whole card multi-function support despite the change to PCHID
   per port. Additionally improve the overall robustness and usability
   of the multifunction support

Pull selinux updates from Paul Moore:

 - Add support for netlink xperms

   Some time ago we added the concept of "xperms" to the SELinux policy
   so that we could write policy for individual ioctls, this builds upon
   this by using extending xperms to netlink so that we can write
   SELinux policy for individual netlnk message types and not rely on
   the fairly coarse read/write mapping tables we currently have.

   There are limitations involving generic netlink due to the
   multiplexing that is done, but it's no worse that what we currently
   have. As usual, more information can be found in the commit message.

 - Deprecate /sys/fs/selinux/user

   We removed the only known userspace use of this back in 2020 and now
   that several years have elapsed we're starting down the path of
   deprecating it in the kernel.

 - Cleanup the build under scripts/selinux

   A couple of patches to move the genheaders tool under
   security/selinux and correct our usage of kernel headers in the tools
   located under scripts/selinux. While these changes originated out of
   an effort to build Linux on different systems, they are arguably the
   right thing to do regardless.

 - Minor code cleanups and style fixes

   Not much to say here, two minor cleanup patches that came out of the
   netlink xperms work

Pull vfs untorn write support from Christian Brauner:
 "An atomic write is a write issed with torn-write protection. This
  means for a power failure or any hardware failure all or none of the
  data from the write will be stored, never a mix of old and new data.

  This work is already supported for block devices. If a block device is
  opened with O_DIRECT and the block device supports atomic write, then
  FMODE_CAN_ATOMIC_WRITE is added to the file of the opened block
  device.

  This contains the work to expand atomic write support to filesystems,
  specifically ext4 and XFS. Currently, only support for writing exactly

Pull tmpfs case folding updates from Christian Brauner:
 "This adds case-insensitive support for tmpfs.

  The work contained in here adds support for case-insensitive file
  names lookups in tmpfs. The main difference from other casefold
  filesystems is that tmpfs has no information on disk, just on RAM, so
  we can't use mkfs to create a case-insensitive tmpfs. For this
  implementation, there's a mount option for casefolding. The rest of
  the patchset follows a similar approach as ext4 and f2fs.

  The use case for this feature is similar to the use case for ext4, to
  better support compatibility layers (like Wine), particularly in
  combination with sandboxing/container tools (like Flatpak).

  Those containerization tools can share a subset of the host filesystem
  with an application. In the container, the root directory and any
  parent directories required for a shared directory are on tmpfs, with
  the shared directories bind-mounted into the container's view of the
  filesystem.

  If the host filesystem is using case-insensitive directories, then the
  application can do lookups inside those directories in a
  case-insensitive way, without this needing to be implemented in
  user-space. However, if the host is only sharing a subset of a
  case-insensitive directory with the application, then the parent
  directories of the mount point will be part of the container's root
  tmpfs. When the application tries to do case-insensitive lookups of
  those parent directories on a case-sensitive tmpfs, the lookup will
  fail"

Pull misc vfs updates from Christian Brauner:
 "Features:

   - Fixup and improve NLM and kNFSD file lock callbacks

     Last year both GFS2 and OCFS2 had some work done to make their
     locking more robust when exported over NFS. Unfortunately, part of
     that work caused both NLM (for NFS v3 exports) and kNFSD (for
     NFSv4.1+ exports) to no longer send lock notifications to clients

     This in itself is not a huge problem because most NFS clients will
     still poll the server in order to acquire a conflicted lock

     It's important for NLM and kNFSD that they do not block their
     kernel threads inside filesystem's file_lock implementations
     because that can produce deadlocks. We used to make sure of this by
     only trusting that posix_lock_file() can correctly handle blocking
     lock calls asynchronously, so the lock managers would only setup
     their file_lock requests for async callbacks if the filesystem did
     not define its own lock() file operation

     However, when GFS2 and OCFS2 grew the capability to correctly
     handle blocking lock requests asynchronously, they started
     signalling this behavior with EXPORT_OP_ASYNC_LOCK, and the check
     for also trusting posix_lock_file() was inadvertently dropped, so
     now most filesystems no longer produce lock notifications when
     exported over NFS

     Fix this by using an fop_flag which greatly simplifies the problem
     and grooms the way for future uses by both filesystems and lock
     managers alike

   - Add a sysctl to delete the dentry when a file is removed instead of
     making it a negative dentry

     Commit 681ce86235 ("vfs: Delete the associated dentry when
     deleting a file") introduced an unconditional deletion of the
     associated dentry when a file is removed. However, this led to
     performance regressions in specific benchmarks, such as
     ilebench.sum_operations/s, prompting a revert in commit
     4a4be1ad3a ("Revert "vfs: Delete the associated dentry when
     deleting a file""). This reintroduces the concept conditionally
     through a sysctl

   - Expand the statmount() system call:

       * Report the filesystem subtype in a new fs_subtype field to
         e.g., report fuse filesystem subtypes

       * Report the superblock source in a new sb_source field

       * Add a new way to return filesystem specific mount options in an
         option array that returns filesystem specific mount options
         separated by zero bytes and unescaped. This allows caller's to
         retrieve filesystem specific mount options and immediately pass
         them to e.g., fsconfig() without having to unescape or split
         them

       * Report security (LSM) specific mount options in a separate
         security option array. We don't lump them together with
         filesystem specific mount options as security mount options are
         generic and most users aren't interested in them

         The format is the same as for the filesystem specific mount
         option array

   - Support relative paths in fsconfig()'s FSCONFIG_SET_STRING command

   - Optimize acl_permission_check() to avoid costly {g,u}id ownership
     checks if possible

   - Use smp_mb__after_spinlock() to avoid full smp_mb() in evict()

   - Add synchronous wakeup support for ep_poll_callback.

     Currently, epoll only uses wake_up() to wake up task. But sometimes
     there are epoll users which want to use the synchronous wakeup flag
     to give a hint to the scheduler, e.g., the Android binder driver.
     So add a wake_up_sync() define, and use wake_up_sync() when sync is
     true in ep_poll_callback()

  Fixes:

   - Fix kernel documentation for inode_insert5() and iget5_locked()

   - Annotate racy epoll check on file->f_ep

   - Make F_DUPFD_QUERY associative

   - Avoid filename buffer overrun in initramfs

   - Don't let statmount() return empty strings

   - Add a cond_resched() to dump_user_range() to avoid hogging the CPU

   - Don't query the device logical blocksize multiple times for hfsplus

   - Make filemap_read() check that the offset is positive or zero

  Cleanups:

   - Various typo fixes

   - Cleanup wbc_attach_fdatawrite_inode()

   - Add hugetlbfs tracepoints

   - Fix various vfs kernel doc parameters

Pull vfs multigrain timestamps from Christian Brauner:
 "This is another try at implementing multigrain timestamps. This time
  with significant help from the timekeeping maintainers to reduce the
  performance impact.

  Thomas provided a base branch that contains the required timekeeping
  interfaces for the VFS. It serves as the base for the multi-grain
  timestamp work:

   - Multigrain timestamps allow the kernel to use fine-grained
     timestamps when an inode's attributes is being actively observed
     via ->getattr(). With this support, it's possible for a file to get
     a fine-grained timestamp, and another modified after it to get a
     coarse-grained stamp that is earlier than the fine-grained time. If
     this happens then the files can appear to have been modified in
     reverse order, which breaks VFS ordering guarantees.

     To prevent this, a floor value is maintained for multigrain
     timestamps. Whenever a fine-grained timestamp is handed out, record
     it, and when later coarse-grained stamps are handed out, ensure
     they are not earlier than that value. If the coarse-grained
     timestamp is earlier than the fine-grained floor, return the floor
     value instead.

     The timekeeper changes add a static singleton atomic64_t into
     timekeeper.c that is used to keep track of the latest fine-grained
     time ever handed out. This is tracked as a monotonic ktime_t value
     to ensure that it isn't affected by clock jumps. Because it is
     updated at different times than the rest of the timekeeper object,
     the floor value is managed independently of the timekeeper via a
     cmpxchg() operation, and sits on its own cacheline.

     Two new public timekeeper interfaces are added:

      (1) ktime_get_coarse_real_ts64_mg() fills a timespec64 with the
          later of the coarse-grained clock and the floor time

      (2) ktime_get_real_ts64_mg() gets the fine-grained clock value,
          and tries to swap it into the floor. A timespec64 is filled
          with the result.

   - The VFS has always used coarse-grained timestamps when updating the
     ctime and mtime after a change. This has the benefit of allowing
     filesystems to optimize away a lot metadata updates, down to around
     1 per jiffy, even when a file is under heavy writes.

     Unfortunately, this has always been an issue when we're exporting
     via NFSv3, which relies on timestamps to validate caches. A lot of
     changes can happen in a jiffy, so timestamps aren't sufficient to
     help the client decide when to invalidate the cache. Even with
     NFSv4, a lot of exported filesystems don't properly support a
     change attribute and are subject to the same problems with
     timestamp granularity. Other applications have similar issues with
     timestamps (e.g backup applications).

     If we were to always use fine-grained timestamps, that would
     improve the situation, but that becomes rather expensive, as the
     underlying filesystem would have to log a lot more metadata
     updates.

     This adds a way to only use fine-grained timestamps when they are
     being actively queried. Use the (unused) top bit in
     inode->i_ctime_nsec as a flag that indicates whether the current
     timestamps have been queried via stat() or the like. When it's set,
     we allow the kernel to use a fine-grained timestamp iff it's
     necessary to make the ctime show a different value.

     This solves the problem of being able to distinguish the timestamp
     between updates, but introduces a new problem: it's now possible
     for a file being changed to get a fine-grained timestamp. A file
     that is altered just a bit later can then get a coarse-grained one
     that appears older than the earlier fine-grained time. This
     violates timestamp ordering guarantees.

     This is where the earlier mentioned timkeeping interfaces help. A
     global monotonic atomic64_t value is kept that acts as a timestamp
     floor. When we go to stamp a file, we first get the latter of the
     current floor value and the current coarse-grained time. If the
     inode ctime hasn't been queried then we just attempt to stamp it
     with that value.

     If it has been queried, then first see whether the current coarse
     time is later than the existing ctime. If it is, then we accept
     that value. If it isn't, then we get a fine-grained time and try to
     swap that into the global floor. Whether that succeeds or fails, we
     take the resulting floor time, convert it to realtime and try to
     swap that into the ctime.

     We take the result of the ctime swap whether it succeeds or fails,
     since either is just as valid.

     Filesystems can opt into this by setting the FS_MGTIME fstype flag.
     Others should be unaffected (other than being subject to the same
     floor value as multigrain filesystems)"
