      random: simplify arithmetic function flow in account() · a254a0e4
      Jason A. Donenfeld authored
      Now that have_bytes is never modified, we can simplify this function.
      First, we move the check for negative entropy_count to be first. That
      ensures that subsequent reads of this will be non-negative. Then,
      have_bytes and ibytes can be folded into their one use site in the
      min_t() function.

      random: selectively clang-format where it makes sense · 248045b8
      Jason A. Donenfeld authored
      This is an old driver that has seen a lot of different eras of kernel
      coding style. In an effort to make it easier to code for, unify the
      coding style around the current norm, by accepting some of -- but
      certainly not all of -- the suggestions from clang-format. This should
      remove ambiguity in coding style, especially with regards to spacing,
      when code is being changed or amended. Consequently it also makes code
      review easier on the eyes, following one uniform style rather than
      several.

      random: access input_pool_data directly rather than through pointer · 6c0eace6
      Jason A. Donenfeld authored
      This gets rid of another abstraction we no longer need. It would be nice
      if we could instead make pool an array rather than a pointer, but the
      latent entropy plugin won't be able to do its magic in that case. So
      instead we put all accesses to the input pool's actual data through the
      input_pool_data array directly.

      Jason A. Donenfeld authored
      The entropy estimator is calculated in terms of 1/8 bits, which means
      there are various constants where things are shifted by 3. Move these
      into our pool info enum with the other relevant constants. While we're
      at it, move an English assertion about sizes into a proper BUILD_BUG_ON
      so that the compiler can ensure this invariant.

      random: remove unused OUTPUT_POOL constants · 0f637027
      Jason A. Donenfeld authored
      We no longer have an output pool. Rather, we have just a wakeup bits
      threshold for /dev/random reads, presumably so that processes don't
      hang. This value, random_write_wakeup_bits, is configurable anyway. So
      all the no longer usefully named OUTPUT_POOL constants were doing was
      setting a reasonable default for random_write_wakeup_bits. This commit
      gets rid of the constants and just puts it all in the default value of
      random_write_wakeup_bits.

      random: rather than entropy_store abstraction, use global · 90ed1e67
      Jason A. Donenfeld authored
      Originally, the RNG used several pools, so having things abstracted out
      over a generic entropy_store object made sense. These days, there's only
      one input pool, and then an uneven mix of usage via the abstraction and
      usage via &input_pool. Rather than this uneasy mixture, just get rid of
      the abstraction entirely and have things always use the global. This
      simplifies the code and makes reading it a bit easier.

      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.

       "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.

      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.

      Pull more ACPI updates from Rafael Wysocki:
       "The most significant item here is the Platform Firmware Runtime Update
        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.
      
        The rest is just a handful of assorted fixes and cleanups on top of
        the ACPI material merged previously.
      
        Specifics:
      
         - Add support for the the Platform Firmware Runtime Update and
           Telemetry (PFRUT) interface based on ACPI to allow certain pieces
           of the platform firmware to be updated without restarting the
           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).
      
         - Drop unnecessary "static" from the ACPI PCC address space handling
           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.
      
         - Enable ignore_missing_thread in 'perf trace'
      
        Fixes:
      
         - Avoid TUI crash when navigating in the annotation of recursive
           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
      
         - Enable system wide for metricgroups test in 'perf test´.
      
         - Use 3 digits for test numbering now we can have more tests.
      
        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'
      
         - Sync UAPI files with the kernel sources: drm, msr-index,
           cpufeatures.
      
        Build system
      
         - Enable warnings through HOSTCFLAGS.
      
         - Drop requirement for libstdc++.so for libopencsd check
      
        libperf:
      
         - Make libperf adopt perf_counts_values__scale() from tools/perf/util/.
      
         - Add a stat multiplexing test to libperf"

      Rafael J. Wysocki authored
      Merge support for the Platform Firmware Runtime Update and Telemetry
      interface based on ACPI.
      
      The interface provided here allows updating certain pieces of the
      platform firmware without restarting the system and collecting
      platform firmware telemetry data.
      
      This also includes a utility for accesing the new interface from user
      space.

      Merge additional ACPI-related updates for 5.17-rc1:
      
       - 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).
      
       - Add more sanity checking to ACPI SPCR tables parsing (Mark
         Langsdorf).
      
       - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).
      
       - Drop unnecessary "static" from the ACPI PCC address space handling
         driver added recently (kernel test robot).
      
      * acpi-x86:
        x86/PCI: Ignore E820 reservations for bridge windows on newer systems

      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()")
