      lib/crypto: sha1: re-roll loops to reduce code size · 9a1536b0
      Jason A. Donenfeld authored
      With SHA-1 no longer being used for anything performance oriented, and
      also soon to be phased out entirely, we can make up for the space added
      by unrolled BLAKE2s by simply re-rolling SHA-1. Since SHA-1 is so much
      more complex, re-rolling it more or less takes care of the code size
      added by BLAKE2s. And eventually, hopefully we'll see SHA-1 removed
      entirely from most small kernel builds.

      lib/crypto: blake2s: move hmac construction into wireguard · d8d83d8a
      Jason A. Donenfeld authored
      Basically nobody should use blake2s in an HMAC construction; it already
      has a keyed variant. But unfortunately for historical reasons, Noise,
      used by WireGuard, uses HKDF quite strictly, which means we have to use
      this. Because this really shouldn't be used by others, this commit moves
      it into wireguard's noise.c locally, so that kernels that aren't using
      WireGuard don't get this superfluous code baked in. On m68k systems,
      this shaves off ~314 bytes.

      lib/crypto: add prompts back to crypto libraries · e56e1898
      Justin M. Forbes authored
      Commit 6048fdcc ("lib/crypto: blake2s: include as built-in") took
      away a number of prompt texts from other crypto libraries. This makes
      values flip from built-in to module when oldconfig runs, and causes
      problems when these crypto libs need to be built in for thingslike
      BIG_KEYS.

      Pull ATA updates from Damien Le Moal:
       "A larger than usual set of changes for this cycle. The bulk of the
        changes are part of a rework of libata messages and debugging features
        from Hannes. In more detail, the changes are as follows.
      
         - Small code cleanups in the pata_ali driver (unnecessary variable
           initialization and simplified return statement, from Jason and
           Colin.
      
         - Switch to using struct_group() in the sata_fsl driver, from Kees.
      
         - Convert many sysfs attribute show functions to use sysfs_emit()
           instead of snprintf(), from me.
      
         - sata_dwc_460ex driver code cleanups, from Andy.
      
         - Improve DMA setup and remove superfluous error message in
           libahci_platform, from Andy
      
         - A small code cleanup in libata to use min() instead of open coding
           test, from Changcheng.
      
         - Rework of libata messages from Hannes. This is especially focused
           on replacing compile time defined debugging messages (DPRINTK() and
           VPRINTK()) with regular dynamic debugging messages (pr_debug()) and
           traceipoint events. Both libata-core and many drivers are updated
           to have a consistent debugging level control for all drivers.
      
         - Extend compile test support to as many drivers as possible in ATA
           Kconfig to improve compile test coverage, from me.
      
         - Fixes to avoid compile time warnings (W=1) and sparse warnings in
           sata_fsl and ahci_xgene drivers, from me.
      
         - Fix the interface of the read_id() port operation method to clarify
           that the data buffer passed as an argument is little endian. This
           avoids sparse warnings in the pata_netcell, pata_it821x,
           ahci_xgene, ahci_cevaxi and ahci_brcm drivers. From me.
      
         - Small code cleanup in the pata_octeon_cf driver, from Minghao.
      
         - Improved IRQ configuration code in pata_of_platform, from Lad.
      
         - Simplified implementation of __ata_scsi_queuecmd(), from Wenchao.
      
         - Debounce delay flag renaming, from Paul.
      
         - Add support for AMD A85 FCH (Hudson D4) AHCI adapters, from Paul"

      vfs: fs_context: fix up param length parsing in legacy_parse_param · 722d9484
      Jamie Hill-Daniel authored
      The "PAGE_SIZE - 2 - size" calculation in legacy_parse_param() is an
      unsigned type so a large value of "size" results in a high positive
      value instead of a negative value as expected.  Fix this by getting rid
      of the subtraction.

        and Telemetry (PFRUT) support designed to allow certain pieces of the
        platform firmware to be updated on the fly, among other things.
      
        Also important is the e820 handling change on x86 that should work
        around PCI BAR allocation issues on some systems shipping since 2019.

           system and to provide a mechanism for collecting platform firmware
           telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).
      
         - Ignore E820 reservations covering PCI host bridge windows on
           sufficiently recent x86 systems to avoid issues with allocating PCI
           BARs on systems where the E820 reservations cover the entire PCI
           host bridge memory window returned by the _CRS object in the
           system's ACPI tables (Hans de Goede).
      
         - Fix and clean up acpi_scan_init() (Rafael Wysocki).
      
         - Add more sanity checking to ACPI SPCR tables parsing (Mark
           Langsdorf).
      
         - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).

           driver added recently (kernel test robot)"

           The original implementation of this command was in the bcc tool.
      
         - Support --cputype option for hybrid events in 'perf stat'.
      
        Improvements:
      
         - Call chain improvements for ARM64.
      
         - No need to do any affinity setup when profiling pids.
      
         - Reduce multiplexing with duration_time in 'perf stat' metrics.
      
         - Improve error message for uncore events, stating that some event
           groups are can only be used in system wide (-a) mode.
      
         - perf stat metric group leader fixes/improvements, including arch
           specific changes to better support Intel topdown events.
      
         - Probe non-deprecated sysfs path first, i.e. try the path
           /sys/devices/system/cpu/cpuN/topology/thread_siblings first, then
           the old /sys/devices/system/cpu/cpuN/topology/core_cpus.
      
         - Disable debuginfod by default in 'perf record', to avoid stalls on
           distros such as Fedora 35.
      
         - Use unbuffered output in 'perf bench' when pipe/tee'ing to a file.

           functions.
      
         - Fix hex dump character output in 'perf script'.
      
         - Fix JSON indentation to 4 spaces standard in the ARM vendor event
           files.
      
         - Fix use after free in metric__new().
      
         - Fix IS_ERR_OR_NULL() usage in the perf BPF loader.
      
         - Fix up cross-arch register support, i.e. when printing register
           names take into account the architecture where the perf.data file
           was collected.
      
         - Fix SMT fallback with large core counts.
      
         - Don't lower case MetricExpr when parsing JSON files so as not to
           lose info such as the ":G" event modifier in metrics.
      
        perf test:
      
         - Add basic stress test for sigtrap handling to 'perf test'.
      
         - Fix 'perf test' failures on s/390

        Arch specific:
      
         - Add events for Arm Neoverse N2 in the ARM JSON vendor event files
      
         - Support PERF_MEM_LVLNUM encodings in powerpc, that came from a
           single patch series, where I incorrectly merged the kernel bits,
           that were then reverted after coordination with Michael Ellerman
           and Stephen Rothwell.
      
         - Add ARM SPE total latency as PERF_SAMPLE_WEIGHT.
      
         - Update AMD documentation, with info on raw event encoding.
      
         - Add support for global and local variants of the "p_stage_cyc" sort
           key, applicable to perf.data files collected on powerpc.
      
         - Remove duplicate and incorrect aux size checks in the ARM CoreSight
           ETM code.
      
        Refactorings:
      
         - Add a perf_cpu abstraction to disambiguate CPUs and CPU map
           indexes, fixing problems along the way.
      
         - Document CPU map methods.
      
        UAPI sync:
      
         - Update arch/x86/lib/mem{cpy,set}_64.S copies used in 'perf bench
           mem memcpy'

      devtmpfs regression fix: reconfigure on each mount · a6097180
      NeilBrown authored
      Prior to Linux v5.4 devtmpfs used mount_single() which treats the given
      mount options as "remount" options, so it updates the configuration of
      the single super_block on each mount.
      
      Since that was changed, the mount options used for devtmpfs are ignored.
      This is a regression which affect systemd - which mounts devtmpfs with
      "-o mode=755,size=4m,nr_inodes=1m".
      
      This patch restores the "remount" effect by calling reconfigure_single()
      
      Fixes: d401727e ("devtmpfs: don't mix {ramfs,shmem}_fill_super() with mount_single()")

       "The biggest change here is in-kernel support for module decompression.
        This change is being made to help support LSMs like LoadPin as
        otherwise it loses link between the source of kernel module on the
        disk and binary blob that is being loaded into the kernel.
      
        kmod decompression is still done by userspace even with this is done,
        both because there are no measurable gains in not doing so and as it
        adds a secondary extra check for validating the module before loading
        it into the kernel.
      
        The rest of the changes are minor, the only other change worth
        mentionin there is Jessica Yu is now bowing out of maintenance of
        modules as she's taking a break from work.
      
        While there were other changes posted for modules, those have not yet

      unicode: fix .gitignore for generated utfdata file · 98f23457
      Linus Torvalds authored
      Commit 2b3d0478 ("unicode: Add utf8-data module") changed the
      generated utf8data file from 'utf8data.h' to 'utf8data.c', but didn't
      change the comments or the .gitignore to match.
      
      The comments should be updated too, but at least they don't cause any
      visible breakage.  But the gitignore file needs changing to avoid git
      complaining about untracked files.

      Pull signal/exit/ptrace updates from Eric Biederman:
       "This set of changes deletes some dead code, makes a lot of cleanups
        which hopefully make the code easier to follow, and fixes bugs found
        along the way.
      
        The end-game which I have not yet reached yet is for fatal signals
        that generate coredumps to be short-circuit deliverable from
        complete_signal, for force_siginfo_to_task not to require changing
        userspace configured signal delivery state, and for the ptrace stops
        to always happen in locations where we can guarantee on all
        architectures that the all of the registers are saved and available on
        the stack.
      
        Removal of profile_task_ext, profile_munmap, and profile_handoff_task
        are the big successes for dead code removal this round.
      
        A bunch of small bug fixes are included, as most of the issues
        reported were small enough that they would not affect bisection so I
        simply added the fixes and did not fold the fixes into the changes
        they were fixing.
      
        There was a bug that broke coredumps piped to systemd-coredump. I
        dropped the change that caused that bug and replaced it entirely with
        something much more restrained. Unfortunately that required some
        rebasing.
      
        Some successes after this set of changes: There are few enough calls
        to do_exit to audit in a reasonable amount of time. The lifetime of
        struct kthread now matches the lifetime of struct task, and the
        pointer to struct kthread is no longer stored in set_child_tid. The
        flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
        removed. Issues where task->exit_code was examined with
        signal->group_exit_code should been examined were fixed.
      
        There are several loosely related changes included because I am
        cleaning up and if I don't include them they will probably get lost.
      
        The original postings of these changes can be found at:
           https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org

        once. Simply because there was less time for review than I had hoped"

         - The Real Time Linux Analysis (RTLA) tool is added to the tools

         - Can safely filter on user space pointers with: field.ustring ~
           "match-string"
      
         - eprobes can now be filtered like any other event.
      
         - trace_marker(_raw) now uses stream_open() to allow multiple threads
           to safely write to it. Note, this could possibly break existing
           user space, but we will not know until we hear about it, and then
           can revert the change if need be.
      
         - New field in events to display when bottom halfs are disabled.
      
         - Sorting of the ftrace functions are now done at compile time
           instead of at bootup.
      
        Infrastructure changes to support future efforts:
      
         - Added __rel_loc type for trace events. Similar to __data_loc but
           the offset to the dynamic data is based off of the location of the
           descriptor and not the beginning of the event. Needed for user
           defined events.
      
         - Some simplification of event trigger code.
      
         - Make synthetic events process its callback better to not hinder
           other event callbacks that are registered. Needed for user defined

       "Bruce has announced he is leaving Red Hat at the end of the month and
        is stepping back from his role as NFSD co-maintainer. As a result,
        this includes a patch removing him from the MAINTAINERS file.
      
        There is one patch in here that Jeff Layton was carrying in the locks
        tree. Since he had only one for this cycle, he asked us to send it to
        you via the nfsd tree.
      
        There continues to be 0-day reports from Robert Morris @MIT. This time
        we include a fix for a crash in the COPY_NOTIFY operation.
      
        Highlights:
         - Bruce steps down as NFSD maintainer
         - Prepare for dynamic nfsd thread management
         - More work on supporting re-exporting NFS mounts
         - One fs/locks patch on behalf of Jeff Layton
