      Pull io_uring updates from Jens Axboe:
       "Fairly quiet round in terms of features, mostly just improvements all
        over the map for existing code. In detail:
      
         - Initial support for socket operations through io_uring. Latter half
           of this will likely land with the 6.7 kernel, then allowing things
           like get/setsockopt (Breno)
      
         - Cleanup of the cancel code, and then adding support for canceling
           requests with the opcode as the key (me)
      
         - Improvements for the io-wq locking (me)
      
         - Fix affinity setting for SQPOLL based io-wq (me)
      
         - Remove the io_uring userspace code. These were added initially as
           copies from liburing, but all of them have since bitrotted and are
           way out of date at this point. Rather than attempt to keep them in
           sync, just get rid of them. People will have liburing available
           anyway for these examples. (Pavel)
      
         - Series improving the CQ/SQ ring caching (Pavel)
      
         - Misc fixes and cleanups (Pavel, Yue, me)"

      Pull sysctl updates from Luis Chamberlain:
       "Long ago we set out to remove the kitchen sink on kernel/sysctl.c
        arrays and placings sysctls to their own sybsystem or file to help
        avoid merge conflicts. Matthew Wilcox pointed out though that if we're
        going to do that we might as well also *save* space while at it and
        try to remove the extra last sysctl entry added at the end of each
        array, a sentintel, instead of bloating the kernel by adding a new
        sentinel with each array moved.
      
        Doing that was not so trivial, and has required slowing down the moves
        of kernel/sysctl.c arrays and measuring the impact on size by each new
        move.
      
        The complex part of the effort to help reduce the size of each sysctl
        is being done by the patient work of el señor Don Joel Granados. A lot
        of this is truly painful code refactoring and testing and then trying
        to measure the savings of each move and removing the sentinels.
        Although Joel already has code which does most of this work,
        experience with sysctl moves in the past shows is we need to be
        careful due to the slew of odd build failures that are possible due to
        the amount of random Kconfig options sysctls use.
      
        To that end Joel's work is split by first addressing the major
        housekeeping needed to remove the sentinels, which is part of this
        merge request. The rest of the work to actually remove the sentinels
        will be done later in future kernel releases.
      
        The preliminary math is showing this will all help reduce the overall
        build time size of the kernel and run time memory consumed by the
        kernel by about ~64 bytes per array where we are able to remove each
        sentinel in the future. That also means there is no more bloating the
        kernel with the extra ~64 bytes per array moved as no new sentinels
        are created"

      Pull modules updates from Luis Chamberlain:
       "Summary of the changes worth highlighting from most interesting to
        boring below:
      
         - Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
           circumvent the protection he put in place in year 2020 to prevent
           proprietary modules from using GPL only symbols, and also ensuring
           proprietary modules which export symbols grandfather their taint.
      
           That was done through year 2020 commit 262e6ae7 ("modules:
           inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by
           clarifing __symbol_get() was only ever intended to prevent module
           reference loops by Linux kernel modules and so making it only find
           symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic
           used by Nvidia was to use symbol_get() to purposely swift through
           proprietary module symbols and completely bypass our traditional
           EXPORT_SYMBOL*() annotations and community agreed upon
           restrictions.
      
           A small set of preamble patches fix up a few symbols which just
           needed adjusting for this on two modules, the rtc ds1685 and the
           networking enetc module. Two other modules just needed some build
           fixing and removal of use of __symbol_get() as they can't ever be
           modular, as was done by Arnd on the ARM pxa module and Christoph
           did on the mmc au1xmmc driver.
      
           This is a good reminder to us that symbol_get() is just a hack to
           address things which should be fixed through Kconfig at build time
           as was done in the later patches, and so ultimately it should just
           go.
      
         - Extremely late minor fix for old module layout 055f23b7
           ("module: check for exit sections in layout_sections() instead of
           module_init_section()") by James Morse for arm64. Note that this
           layout thing is old, it is *not* Song Liu's commit ac3b4328
           ("module: replace module_layout with module_memory"). The issue
           however is very odd to run into and so there was no hurry to get
           this in fast.
      
         - Although the fix did not go through the modules tree I'd like to
           highlight the fix by Peter Zijlstra in commit 54097309
           ("x86/static_call: Fix __static_call_fixup()") now merged in your
           tree which came out of what was originally suspected to be a
           fallout of the the newer module layout changes by Song Liu commit
           ac3b4328 ("module: replace module_layout with module_memory")
           instead of module_init_section()"). Thanks to the report by
           Christian Bricart and the debugging by Song Liu & Peter that turned
           to be noted as a kernel regression in place since v5.19 through
           commit ee88d363 ("x86,static_call: Use alternative RET
           encoding").
      
           I highlight this to reflect and clarify that we haven't seen more
           fallout from ac3b4328 ("module: replace module_layout with
           module_memory").
      
         - RISC-V toolchain got mapping symbol support which prefix symbols
           with "$" to help with alignment considerations for disassembly.
      
           This is used to differentiate between incompatible instruction
           encodings when disassembling. RISC-V just matches what ARM/AARCH64
           did for alignment considerations and Palmer Dabbelt extended
           is_mapping_symbol() to accept these symbols for RISC-V. We already
           had support for this for all architectures but it also checked for
           the second character, the RISC-V check Dabbelt added was just for
           the "$". After a bit of testing and fallout on linux-next and based
           on feedback from Masahiro Yamada it was decided to simplify the
           check and treat the first char "$" as unique for all architectures,
           and so we no make is_mapping_symbol() for all archs if the symbol
           starts with "$".
      
           The most relevant commit for this for RISC-V on binutils was:
      
             https://sourceware.org/pipermail/binutils/2021-July/117350.html
      
         - A late fix by Andrea Righi (today) to make module zstd
           decompression use vmalloc() instead of kmalloc() to account for
           large compressed modules. I suspect we'll see similar things for
           other decompression algorithms soon.
      
         - samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and
           Chen Jiahao"

         - Randomized kmalloc caches, by GONG, Ruiqi.
      
           A new opt-in hardening feature to make heap spraying harder. It
           creates multiple (16) copies of kmalloc caches, reducing the chance
           of an attacker-controllable allocation site to land in the same
           slab as e.g. an allocation site with use-after-free vulnerability.
      
           The selection of the copy is derived from the allocation site
           address, including a per-boot random seed.
      
         - Stronger typing for hardened freelists in SLUB, by Jann Horn
      
           Introduces a custom type for hardened freelist entries instead of
           "void *" as those are not directly dereferencable. While reviewing
           this, I've noticed opportunities for further cleanups in that code
           and added those on top"

         - Move a misplaced lockep assertion before we potentially free the

           as long as a superblock still appears on the filesystem type's

           What we want as a proper solution for next cycle is to split
           sb->free_sb() out of sb->kill_sb() so that we can simply call
           kill_super_notify() after sb->kill_sb() but before sb->free_sb().

      Pull gpio updates from Bartosz Golaszewski:
       "We have a lot of code refactoring using common helpers and ended up
        removing more lines then we're adding this release cycle.
      
        Nothing really stands out, just small updates all over the place.
      
        Core GPIOLIB updates:
         - wake-up poll() in user-space on device unbind
         - improve fwnode usage
         - interrupt domain handling improvements
         - correctly handle the ngpios property in gpio-mmio
      
        Driver cleanups:
         - remove unneeded calls to platform_set_drvdata() all around the
           place
         - remove unneeded of_match_ptr() expansions whenever a driver depends
           on CONFIG_OF
         - remove redundant calls to dev_err_probe() from gpio-omap and
           gpio-davinci
      
        Driver improvements:
         - use autopointers and guards from cleanup.h in gpio-sim
         - shrink code in gpio-sim using some common helpers
         - convert the idio family of drivers to using gpio-regmap
         - convert gpio-ws16c48 to using gpio-regmap
         - use devres to simplify code in gpio-pisosr and gpio-mxc
         - update gpio-sifive: support IRQ wake, improve interrupt handling,
           allow building as module
         - make gpio-ge and gpio-bcm-kona OF-independent (plus some minor
           tweaks)
         - add support for new models in gpio-pca953x and gpio-ds4520
         - add runtime PM support to gpio-mxc
         - fix a build warning in gpio-mxs
         - add support for adding pin ranges to gpio-mlxbf3
         - add counter/timer support to gpio-104-dio-48e
         - switch to dynamic GPIO base allocation in gpio-vf610
         - minor oneliners here and there
      
        Device-tree bindings updates:
         - enable the gpio-line-names property in snps,dw-apb and STMPE GPIO
         - document new models in fsl-imx-gpio, ds4520 and pca95xx
         - convert the bindings for brcm,kona-gpio to YAML"

      Linus Torvalds authored
      Pull rust updates from Miguel Ojeda:
       "In terms of lines, most changes this time are on the pinned-init API
        and infrastructure. While we have a Rust version upgrade, and thus a
        bunch of changes from the vendored 'alloc' crate as usual, this time
        those do not account for many lines.
      
        Toolchain and infrastructure:
      
         - Upgrade to Rust 1.71.1. This is the second such upgrade, which is a
           smaller jump compared to the last time.
      
           This version allows us to remove the '__rust_*' allocator functions
           -- the compiler now generates them as expected, thus now our
           'KernelAllocator' is used.
      
           It also introduces the 'offset_of!' macro in the standard library
           (as an unstable feature) which we will need soon. So far, we were
           using a declarative macro as a prerequisite in some not-yet-landed
           patch series, which did not support sub-fields (i.e. nested
           structs):
      
               #[repr(C)]
               struct S {
                   a: u16,
                   b: (u8, u8),
               }
      
               assert_eq!(offset_of!(S, b.1), 3);
      
         - Upgrade to bindgen 0.65.1. This is the first time we upgrade its
           version.
      
           Given it is a fairly big jump, it comes with a fair number of
           improvements/changes that affect us, such as a fix needed to
           support LLVM 16 as well as proper support for '__noreturn' C
           functions, which are now mapped to return the '!' type in Rust:
      
               void __noreturn f(void); // C
               pub fn f() -> !;         // Rust
      
         - 'scripts/rust_is_available.sh' improvements and fixes.
      
           This series takes care of all the issues known so far and adds a
           few new checks to cover for even more cases, plus adds some more
           help texts. All this together will hopefully make problematic
           setups easier to identify and to be solved by users building the
           kernel.
      
           In addition, it adds a test suite which covers all branches of the
           shell script, as well as tests for the issues found so far.
      
         - Support rust-analyzer for out-of-tree modules too.
      
         - Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates.
      
         - Drop 'scripts/is_rust_module.sh' since it is not needed anymore.
      
        Macros crate:
      
         - New 'paste!' proc macro.
      
           This macro is a more flexible version of 'concat_idents!': it
           allows the resulting identifier to be used to declare new items and
           it allows to transform the identifiers before concatenating them,
           e.g.
      
               let x_1 = 42;
               paste!(let [<x _2>] = [<x _1>];);
               assert!(x_1 == x_2);
      
           The macro is then used for several of the pinned-init API changes
           in this pull.
      
        Pinned-init API:
      
         - Make '#[pin_data]' compatible with conditional compilation of
           fields, allowing to write code like:
      
               #[pin_data]
               pub struct Foo {
                   #[cfg(CONFIG_BAR)]
                   a: Bar,
                   #[cfg(not(CONFIG_BAR))]
                   a: Baz,
               }
      
         - New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait,
           which allows 'unsafe' implementations for structs where every field
           implements the 'Zeroable' trait, e.g.:
      
               #[derive(Zeroable)]
               pub struct DriverData {
                   id: i64,
                   buf_ptr: *mut u8,
                   len: usize,
               }
      
         - Add '..Zeroable::zeroed()' syntax to the 'pin_init!' macro for
           zeroing all other fields, e.g.:
      
               pin_init!(Buf {
                   buf: [1; 64],
                   ..Zeroable::zeroed()
               });
      
         - New '{,pin_}init_array_from_fn()' functions to create array
           initializers given a generator function, e.g.:
      
               let b: Box<[usize; 1_000]> = Box::init::<Error>(
                   init_array_from_fn(|i| i)
               ).unwrap();
      
               assert_eq!(b.len(), 1_000);
               assert_eq!(b[123], 123);
      
         - New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to
           execute a closure on the value directly after initialization, e.g.:
      
               let foo = init!(Foo {
                   buf <- init::zeroed()
               }).chain(|foo| {
                   foo.setup();
                   Ok(())
               });
      
         - Support arbitrary paths in init macros, instead of just identifiers
           and generic types.
      
         - Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and
           'Opaque<T>' types.
      
         - Make initializer values inaccessible after initialization.
      
         - Make guards in the init macros hygienic.
      
        'allocator' module:
      
         - Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing
           misaligned allocations when the Rust 1.71.1 upgrade is applied
           later in this pull.
      
           The equivalent fix for the previous compiler version (where
           'KernelAllocator' is not yet used) was merged into 6.5 already,
           which added the 'krealloc_aligned()' function used here.
      
         - Implement 'KernelAllocator::{realloc, alloc_zeroed}' for
           performance, using 'krealloc_aligned()' too, which forwards the
           call to the C API.
      
        'types' module:
      
         - Make 'Opaque' be '!Unpin', removing the need to add a
           'PhantomPinned' field to Rust structs that contain C structs which
           must not be moved.
      
         - Make 'Opaque' use 'UnsafeCell' as the outer type, rather than
           inner.
      
        Documentation:
      
         - Suggest obtaining the source code of the Rust's 'core' library
           using the tarball instead of the repository.

      Merge branch 'slab/for-6.6/random_kmalloc' into slab/for-next · 3d053e80
      Vlastimil Babka authored
      Merge the new hardening feature to make heap spraying harder, by GONG,
      Ruiqi. It creates multiple (16) copies of kmalloc caches, reducing the
      chance of an attacker-controllable allocation site to land in the same
      slab as e.g.  an allocation site with use-after-free vulnerability. The
      selection of the copy is derived from the allocation site address,
      including a per-boot random seed.
      
      In line with SLAB deprecation, this is a SLUB only feature, incompatible
      with SLUB_TINY due to the memory overhead of the extra cache copies.

      super: ensure valid info · dc3216b1
      Christian Brauner authored
      For keyed filesystems that recycle superblocks based on s_fs_info or
      information contained therein s_fs_info must be kept as long as the
      superblock is on the filesystem type super list. This isn't guaranteed
      as s_fs_info will be freed latest in sb->kill_sb().
      
      The fix is simply to perform notification and list removal in
      kill_anon_super(). Any filesystem needs to free s_fs_info after they
      call the kill_*() helpers. If they don't they risk use-after-free right
      now so fixing it here is guaranteed that s_fs_info remain valid.
      
      For block backed filesystems notifying in pass sb->kill_sb() in
      deactivate_locked_super() remains unproblematic and is required because
      multiple other block devices can be shut down after kill_block_super()
      has been called from a filesystem's sb->kill_sb() handler. For example,
      ext4 and xfs close additional devices. Block based filesystems don't
      depend on s_fs_info (btrfs does use s_fs_info but also uses
      kill_anon_super() and not kill_block_super().).
      
      Sorry for that braino. Goal should be to unify this behavior during this
      cycle obviously. But let's please do a simple bugfix now.

      Pull thermal control updates from Rafael Wysocki:
       "These rework the Intel DTS IOSF and the ACPI thermal drivers to pass
        tables of generic trip point structures to the core during
        initialization and make some requisite modifications in the thermal
        core, fix a few issues elsewhere and clean up code.
      
        This includes changes that are present in the ACPI updates too,
        because they involve both ACPI and the thermal core. The list of
        specific changes below is limited to thermal control, however.
      
        Specifics:
      
         - Make the ACPI thermal driver use its own Notify() handler (Michal
           Wilczynski)
      
         - Rework the ACPI thermal driver to use a table of generic trip point
           structures on top of the internal representation of trip points and
           remove thermal zone callbacks that are not necessary any more from
           that driver (Rafael Wysocki)
      
         - Fix a few issues in the Intel DTS IOSF thermal driver, clean up
           code in it and make it pass tables of generic trip point structures
           to the core during thermal zone registration (Rafael Wysocki)
      
         - Drop a redundant check from the Intel DTS IOSF thermal driver's
           "remove" routine (Zhang Rui)
      
         - Use module_platform_driver() to replace an open-coded counterpart
           of it in the int340x thermal driver (Yang Yingliang)
      
         - Fix possible uninitialized value access in __thermal_of_bind() and
           __thermal_of_unbind() (Peng Fan)
      
         - Make the int3400 driver use thermal zone device wrappers (Daniel
           Lezcano)
      
         - Remove redundant thermal zone state check from the int340x thermal
           driver (Daniel Lezcano)
      
         - Drop non-functional nocrt parameter from ACPI thermal (Mario
           Limonciello)
      
         - Explicitly include correct DT includes in the thermal core and
           drivers (Rob Herring)"

      Pull arm64 updates from Will Deacon:
       "I think we have a bit less than usual on the architecture side, but
        that's somewhat balanced out by a large crop of perf/PMU driver
        updates and extensions to our selftests.
      
        CPU features and system registers:
      
         - Advertise hinted conditional branch support (FEAT_HBC) to userspace
      
         - Avoid false positive "SANITY CHECK" warning when xCR registers
           differ outside of the length field
      
        Documentation:
      
         - Fix macro name typo in SME documentation
      
        Entry code:
      
         - Unmask exceptions earlier on the system call entry path
      
        Memory management:
      
         - Don't bother clearing PTE_RDONLY for dirty ptes in pte_wrprotect()
           and pte_modify()
      
        Perf and PMU drivers:
      
         - Initial support for Coresight TRBE devices on ACPI systems (the
           coresight driver changes will come later)
      
         - Fix hw_breakpoint single-stepping when called from bpf
      
         - Fixes for DDR PMU on i.MX8MP SoC
      
         - Add NUMA-awareness to Hisilicon PCIe PMU driver
      
         - Fix locking dependency issue in Arm DMC620 PMU driver
      
         - Workaround Hisilicon erratum 162001900 in the SMMUv3 PMU driver
      
         - Add support for Arm CMN-700 r3 parts to the CMN PMU driver
      
         - Add support for recent Arm Cortex CPU PMUs
      
         - Update Hisilicon PMU maintainers
      
        Selftests:
      
         - Add a bunch of new features to the hwcap test (JSCVT, PMULL, AES,
           SHA1, etc)
      
         - Fix SSVE test to leave streaming-mode after grabbing the signal
           context
      
         - Add new test for SVE vector-length changes with SME enabled
      
        Miscellaneous:
      
         - Allow compiler to warn on suspicious looking system register
           expressions
      
         - Work around SDEI firmware bug by aborting any running handlers on a
           kernel crash
      
         - Fix some harmless warnings when building with W=1
      
         - Remove some unused function declarations
      
         - Other minor fixes and cleanup"

      Linus Torvalds authored
      Pull s390 updates from Heiko Carstens:
      
       - Add vfio-ap support to pass-through crypto devices to secure
         execution guests
      
       - Add API ordinal 6 support to zcrypt_ep11misc device drive, which is
         required to handle key generate and key derive (e.g. secure key to
         protected key) correctly
      
       - Add missing secure/has_secure sysfs files for the case where it is
         not possible to figure where a system has been booted from. Existing
         user space relies on that these files are always present
      
       - Fix DCSS block device driver list corruption, caused by incorrect
         error handling
      
       - Convert virt_to_pfn() and pfn_to_virt() from defines to static inline
         functions to enforce type checking
      
       - Cleanups, improvements, and minor fixes to the kernel mapping setup
      
       - Fix various virtual vs physical address confusions
      
       - Move pfault code to separate file, since it has nothing to do with
         regular fault handling
      
       - Move s390 documentation to Documentation/arch/ like it has been done
         for other architectures already
      
       - Add HAVE_FUNCTION_GRAPH_RETVAL support
      
       - Factor out the s390_hypfs filesystem and add a new config option for
         it. The filesystem is deprecated and as soon as all users are gone it
         can be removed some time in the not so near future
      
       - Remove support for old CEX2 and CEX3 crypto cards from zcrypt device
         driver
      
       - Add support for user-defined certificates: receive user-defined
         certificates with a diagnose call and provide them via 'cert_store'
         keyring to user space
      
       - Couple of other small fixes and improvements all over the place
      
      * tag 's390-6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (66 commits)
