      Merge tag 'statx-dioalign-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux
      
      Pull STATX_DIOALIGN support from Eric Biggers:
       "Make statx() support reporting direct I/O (DIO) alignment information.
      
        This provides a generic interface for userspace programs to determine
        whether a file supports DIO, and if so with what alignment
        restrictions. Specifically, STATX_DIOALIGN works on block devices, and
        on regular files when their containing filesystem has implemented
        support.
      
        An interface like this has been requested for years, since the
        conditions for when DIO is supported in Linux have gotten increasingly
        complex over time. Today, DIO support and alignment requirements can
        be affected by various filesystem features such as multi-device
        support, data journalling, inline data, encryption, verity,
        compression, checkpoint disabling, log-structured mode, etc.
      
        Further complicating things, Linux v6.0 relaxed the traditional rule
        of DIO needing to be aligned to the block device's logical block size;
        now user buffers (but not file offsets) only need to be aligned to the
        DMA alignment.
      
        The approach of uplifting the XFS specific ioctl XFS_IOC_DIOINFO was
        discarded in favor of creating a clean new interface with statx().

      Linus Torvalds authored
      Pull nfsd updates from Chuck Lever:
       "This release is mostly bug fixes, clean-ups, and optimizations.
      
        One notable set of fixes addresses a subtle buffer overflow issue that
        occurs if a small RPC Call message arrives in an oversized RPC record.
        This is only possible on a framed RPC transport such as TCP.
      
        Because NFSD shares the receive and send buffers in one set of pages,
        an oversized RPC record steals pages from the send buffer that will be
        used to construct the RPC Reply message. NFSD must not assume that a
        full-sized buffer is always available to it; otherwise, it will walk
        off the end of the send buffer while constructing its reply.
      
        In this release, we also introduce the ability for the server to wait
        a moment for clients to return delegations before it responds with
        NFS4ERR_DELAY. This saves a retransmit and a network round- trip when
        a delegation recall is needed. This work will be built upon in future
        releases.
      
        The NFS server adds another shrinker to its collection. Because
        courtesy clients can linger for quite some time, they might be
        freeable when the server host comes under memory pressure. A new
        shrinker has been added that releases courtesy client resources during
        low memory scenarios.
      
        Lastly, of note: the maximum number of operations per NFSv4 COMPOUND
        that NFSD can handle is increased from 16 to 50. There are NFSv4
        client implementations that need more than 16 to successfully perform
        a mount operation that uses a pathname with many components"

       "In this cycle, for container use cases, fscache-based shared domain is
        introduced [1] so that data blobs in the same domain will be storage
        deduplicated and it will also be used for page cache sharing later.
      
        Also, a special packed inode is now introduced to record inode
        fragments which keep the tail part of files by Yue Hu [2]. You can
        keep arbitary length or (at will) the whole file as a fragment and
        then fragments can be optionally compressed in the packed inode
        together and even deduplicated for smaller image sizes.
      
        In addition to that, global compressed data deduplication by sharing
        partial-referenced pclusters is also supported in this cycle.
      
        Summary:
      
         - Introduce fscache-based domain to share blobs between images
      
         - Support recording fragments in a special packed inode

      Pull fatfs vfsuid conversion from Christian Brauner:
       "Last cycle we introduced the new vfs{g,u}id_t types that we had agreed
        on. The most important parts of the vfs have been converted but there
        are a few more places we need to switch before we can remove the old
        helpers completely.
      
        This cycle we converted all filesystems that called idmapped mount
        helpers directly. The affected filesystems are f2fs, fat, fuse, ksmbd,
        overlayfs, and xfs. We've sent patches for all of them. Looking at
        -next f2fs, ksmbd, overlayfs, and xfs have all picked up these patches
        and they should land in mainline during the v6.1 merge window.
      
        So all filesystems that have a separate tree should send the vfsuid
        conversion themselves. Onle the fat conversion is going through this
        generic fs trees because there is no fat tree.
      
        In order to change time settings on an inode fat checks that the
        caller either is the owner of the inode or the inode's group is in the
        caller's group list. If fat is on an idmapped mount we compare whether
        the inode mapped into the mount is equivalent to the caller's fsuid.
        If it isn't we compare whether the inode's group mapped into the mount
        is in the caller's group list.
      
        We now use the new vfsuid based helpers for that"

      Linus Torvalds authored
      Pull vfs acl updates from Christian Brauner:
       "These are general fixes and preparatory changes related to the ongoing
        posix acl rework. The actual rework where we build a type safe posix
        acl api wasn't ready for this merge window but we're hopeful for the
        next merge window.
      
        General fixes:
      
         - Some filesystems like 9p and cifs have to implement custom posix
           acl handlers because they require access to the dentry in order to
           set and get posix acls while the set and get inode operations
           currently don't. But the ntfs3 filesystem has no such requirement
           and thus implemented custom posix acl xattr handlers when it really
           didn't have to. So this pr contains patch that just implements set
           and get inode operations for ntfs3 and switches it to rely on the
           generic posix acl xattr handlers. (We would've appreciated reviews
           from the ntfs3 maintainers but we didn't get any. But hey, if we
           really broke it we'll fix it. But fstests for ntfs3 said it's
           fine.)
      
         - The posix_acl_fix_xattr_common() helper has been adapted so it can
           be used by a few more callers and avoiding open-coding the same
           checks over and over.
      
        Other than the two general fixes this series introduces a new helper
        vfs_set_acl_prepare(). The reason for this helper is so that we can
        mitigate one of the source that change {g,u}id values directly in the
        uapi struct. With the vfs_set_acl_prepare() helper we can move the
        idmapped mount fixup into the generic posix acl set handler.
      
        The advantage of this is that it allows us to remove the
        posix_acl_setxattr_idmapped_mnt() helper which so far we had to call
        in vfs_setxattr() to account for idmapped mounts. While semantically
        correct the problem with this approach was that we had to keep the
        value parameter of the generic vfs_setxattr() call as non-const. This
        is rectified in this series.
      
        Ultimately, we will get rid of all the extreme kludges and type
        unsafety once we have merged the posix api - hopefully during the next
        merge window - built solely around get and set inode operations. Which
        incidentally will also improve handling of posix acls in security and
        especially in integrity modesl. While this will come with temporarily
        having two inode operation for posix acls that is nothing compared to
        the problems we have right now and so well worth it. We'll end up with
        something that we can actually reason about instead of needing to
        write novels to explain what's going on"

      Pull LSM updates from Paul Moore:
       "Seven patches for the LSM layer and we've got a mix of trivial and
        significant patches. Highlights below, starting with the smaller bits
        first so they don't get lost in the discussion of the larger items:
      
         - Remove some redundant NULL pointer checks in the common LSM audit
           code.
      
         - Ratelimit the lockdown LSM's access denial messages.
      
           With this change there is a chance that the last visible lockdown
           message on the console is outdated/old, but it does help preserve
           the initial series of lockdown denials that started the denial
           message flood and my gut feeling is that these might be the more
           valuable messages.
      
         - Open userfaultfds as readonly instead of read/write.
      
           While this code obviously lives outside the LSM, it does have a
           noticeable impact on the LSMs with Ondrej explaining the situation
           in the commit description. It is worth noting that this patch
           languished on the VFS list for over a year without any comments
           (objections or otherwise) so I took the liberty of pulling it into
           the LSM tree after giving fair notice. It has been in linux-next
           since the end of August without any noticeable problems.
      
         - Add a LSM hook for user namespace creation, with implementations
           for both the BPF LSM and SELinux.
      
           Even though the changes are fairly small, this is the bulk of the
           diffstat as we are also including BPF LSM selftests for the new
           hook.
      
           It's also the most contentious of the changes in this pull request
           with Eric Biederman NACK'ing the LSM hook multiple times during its
           development and discussion upstream. While I've never taken NACK's
           lightly, I'm sending these patches to you because it is my belief
           that they are of good quality, satisfy a long-standing need of
           users and distros, and are in keeping with the existing nature of
           the LSM layer and the Linux Kernel as a whole.
      
           The patches in implement a LSM hook for user namespace creation
           that allows for a granular approach, configurable at runtime, which
           enables both monitoring and control of user namespaces. The general
           consensus has been that this is far preferable to the other
           solutions that have been adopted downstream including outright
           removal from the kernel, disabling via system wide sysctls, or
           various other out-of-tree mechanisms that users have been forced to
           adopt since we haven't been able to provide them an upstream
           solution for their requests. Eric has been steadfast in his
           objections to this LSM hook, explaining that any restrictions on
           the user namespace could have significant impact on userspace.
           While there is the possibility of impacting userspace, it is
           important to note that this solution only impacts userspace when it
           is requested based on the runtime configuration supplied by the
           distro/admin/user. Frederick (the pathset author), the LSM/security
           community, and myself have tried to work with Eric during
           development of this patchset to find a mutually acceptable
           solution, but Eric's approach and unwillingness to engage in a
           meaningful way have made this impossible. I have CC'd Eric directly
           on this pull request so he has a chance to provide his side of the
           story; there have been no objections outside of Eric's"

       "Six SELinux patches, all are simple and easily understood, but a list
        of the highlights is below:
      
         - Use 'grep -E' instead of 'egrep' in the SELinux policy install
           script.
      
           Fun fact, this seems to be GregKH's *second* dedicated SELinux
           patch since we transitioned to git (ignoring merges, the SPDX
           stuff, and a trivial fs reference removal when lustre was yanked);
           the first was back in 2011 when selinuxfs was placed in
           /sys/fs/selinux. Oh, the memories ...
      
         - Convert the SELinux policy boolean values to use signed integer
           types throughout the SELinux kernel code.
      
           Prior to this we were using a mix of signed and unsigned integers
           which was probably okay in this particular case, but it is
           definitely not a good idea in general.
      
         - Remove a reference to the SELinux runtime disable functionality in
           /etc/selinux/config as we are in the process of deprecating that.
      
           See [1] for more background on this if you missed the previous

      Pull kernel hardening updates from Kees Cook:
       "Most of the collected changes here are fixes across the tree for
        various hardening features (details noted below).
      
        The most notable new feature here is the addition of the memcpy()
        overflow warning (under CONFIG_FORTIFY_SOURCE), which is the next step
        on the path to killing the common class of "trivially detectable"
        buffer overflow conditions (i.e. on arrays with sizes known at compile
        time) that have resulted in many exploitable vulnerabilities over the
        years (e.g. BleedingTooth).
      
        This feature is expected to still have some undiscovered false
        positives. It's been in -next for a full development cycle and all the
        reported false positives have been fixed in their respective trees.
        All the known-bad code patterns we could find with Coccinelle are also
        either fixed in their respective trees or in flight.
      
        The commit message in commit 54d9469b ("fortify: Add run-time WARN
        for cross-field memcpy()") for the feature has extensive details, but
        I'll repeat here that this is a warning _only_, and is not intended to
        actually block overflows (yet). The many patches fixing array sizes
        and struct members have been landing for several years now, and we're
        finally able to turn this on to find any remaining stragglers.
      
        Summary:
      
        Various fixes across several hardening areas:
      
         - loadpin: Fix verity target enforcement (Matthias Kaehlcke).
      
         - zero-call-used-regs: Add missing clobbers in paravirt (Bill
           Wendling).
      
         - CFI: clean up sparc function pointer type mismatches (Bart Van
           Assche).
      
         - Clang: Adjust compiler flag detection for various Clang changes
           (Sami Tolvanen, Kees Cook).
      
         - fortify: Fix warnings in arch-specific code in sh, ARM, and xen.
      
        Improvements to existing features:
      
         - testing: improve overflow KUnit test, introduce fortify KUnit test,
           add more coverage to LKDTM tests (Bart Van Assche, Kees Cook).
      
         - overflow: Relax overflow type checking for wider utility.
      
        New features:
      
         - string: Introduce strtomem() and strtomem_pad() to fill a gap in
           strncpy() replacement needs.
      
         - um: Enable FORTIFY_SOURCE support.
      
         - fortify: Enable run-time struct member memcpy() overflow warning"

       "The tree has a recent base, but has fundamentally been in linux-next

        Kernel Maintainer's Summit, and to gain recent Reviewed-by: tags.
      
        Miguel is the primary maintainer, with me helping where needed/wanted.
        Our plan is for the tree to switch to the standard non-rebasing
        practice once this initial infrastructure series lands.
      
        The contents are the absolute minimum to get Rust code building in the
        kernel, with many more interfaces[2] (and drivers - NVMe[3], 9p[4], M1
        GPU[5]) on the way.
      
        The initial support of Rust-for-Linux comes in roughly 4 areas:
      
         - Kernel internals (kallsyms expansion for Rust symbols, %pA format)
      
         - Kbuild infrastructure (Rust build rules and support scripts)
      
         - Rust crates and bindings for initial minimum viable build
      
         - Rust kernel documentation and samples
      
        Rust support has been in linux-next for a year and a half now, and the
        short log doesn't do justice to the number of people who have
        contributed both to the Linux kernel side but also to the upstream
        Rust side to support the kernel's needs. Thanks to these 173 people,

      Pull thermal control updates from Rafael Wysocki:
       "The most significant part of this update is the thermal control DT
        initialization rework from Daniel Lezcano and the following conversion
        of drivers to use the new API introduced by it
      
        Apart from that, the maximum number of trip points in a thermal zone
        is increased and there are some fixes and code cleanups
      
        Specifics:
      
         - Rework the device tree initialization, convert the drivers to the
           new API and remove the old OF code (Daniel Lezcano)
      
         - Fix return value to -ENODEV when searching for a specific thermal
           zone which does not exist (Daniel Lezcano)

           when unregistering a thermal zone (Daniel Lezcano)
      
         - Move the set_trip ops inside the therma sysfs code (Daniel Lezcano)
      
         - Remove unnecessary error message as it is already shown in the
           underlying function (Jiapeng Chong)
      
         - Rework the monitoring path and move the locks upper in the call
           stack to fix some potentials race windows (Daniel Lezcano)
      
         - Fix lockdep_assert() warning introduced by the lock rework (Daniel
           Lezcano)
      
         - Do not lock thermal zone mutex in the user space governor (Rafael
           Wysocki)
      
         - Revert the Mellanox 'hotter thermal zone' feature because it is
           already handled in the thermal framework core code (Daniel Lezcano)
      
         - Increase maximum number of trip points in the thermal core (Sumeet
           Pawnikar)
      
         - Replace strlcpy() with unused retval with strscpy() in the core
           thermal control code (Wolfram Sang)
      
         - Use module_pci_driver() macro in the int340x processor_thermal
           driver (Shang XiaoJing)
      
         - Use get_cpu() instead of smp_processor_id() in the intel_powerclamp
           thermal driver to prevent it from crashing and remove unused
           accounting for IRQ wakes from it (Srinivas Pandruvada)
      
         - Consolidate priv->data_vault checks in int340x_thermal (Rafael

      Linus Torvalds authored
      Pull RCU updates from Paul McKenney:
      
       - Documentation updates.
      
         This is the first in a series from an ongoing review of the RCU
         documentation. "Why are people thinking -that- about RCU? Oh. Because
         that is an entirely reasonable interpretation of its documentation."
      
       - Miscellaneous fixes.
      
       - Improved memory allocation and heuristics.
      
       - Improve rcu_nocbs diagnostic output.
      
       - Add full-sized polled RCU grace period state values.
      
         These are the same size as an rcu_head structure, which is double
         that of the traditional unsigned long state values that may still be
         obtained from et_state_synchronize_rcu(). The added size avoids
         missing overlapping grace periods. This benefit is that call_rcu()
         can be replaced by polling, which can be attractive in situations
         where RCU-protected data is aged out of memory.
      
         Early in the series, the size of this state value is three unsigned
         longs. Later in the series, the fastpaths in synchronize_rcu() and
         synchronize_rcu_expedited() are reworked to permit the full state to
         be represented by only two unsigned longs. This reworking slows these
         two functions down in SMP kernels running either on single-CPU
         systems or on systems with all but one CPU offlined, but this should
         not be a significant problem. And if it somehow becomes a problem in
         some yet-as-unforeseen situations, three-value state values can be
         provided for only those situations.
      
         Finally, a pair of functions named same_state_synchronize_rcu() and
         same_state_synchronize_rcu_full() allow grace-period state values to
         be compared for equality. This permits users to maintain lists of
         data structures having the same state value, removing the need for
         per-data-structure grace-period state values, thus decreasing memory
         footprint.
      
       - Polled SRCU grace-period updates, including adding tests to
         rcutorture and reducing the incidence of Tiny SRCU grace-period-state
         counter wrap.
      
       - Improve Tasks RCU diagnostics and quiescent-state detection.

          Supported targets under selftests/nolibc:
            all          call the "run" target below
            help         this help
            sysroot      create the nolibc sysroot here (uses $ARCH)
            nolibc-test  build the executable (uses $CC and $CROSS_COMPILE)
            initramfs    prepare the initramfs with nolibc-test
            defconfig    create a fresh new default config (uses $ARCH)
            kernel       (re)build the kernel with the initramfs (uses $ARCH)
            run          runs the kernel in QEMU after building it (uses $ARCH, $TEST)
            rerun        runs a previously prebuilt kernel in QEMU (uses $ARCH, $TEST)
            clean        clean the sysroot, initramfs, build and output files
      
          The output file is "run.out". Test ranges may be passed using $TEST.
      
          Currently using the following variables:
            ARCH          = x86

            IMAGE_NAME    = bzImage [determined from $ARCH]
      
        The output of a successful x86 "make run" is currently as follows,
        with kernel build output omitted:
      
          $ make run
          71 test(s) passed."
