      Merge tag 'y2038-drivers-for-v5.6-signed' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground
      
      Pull y2038 updates from Arnd Bergmann:
       "Core, driver and file system changes
      
        These are updates to device drivers and file systems that for some
        reason or another were not included in the kernel in the previous
        y2038 series.
      
        I've gone through all users of time_t again to make sure the kernel is
        in a long-term maintainable state, replacing all remaining references
        to time_t with safe alternatives.
      
        Some related parts of the series were picked up into the nfsd, xfs,
        alsa and v4l2 trees. A final set of patches in linux-mm removes the
        now unused time_t/timeval/timespec types and helper functions after
        all five branches are merged for linux-5.6, ensuring that no new users
        get merged.
      
        As a result, linux-5.6, or my backport of the patches to 5.4 [1],
        should be the first release that can serve as a base for a 32-bit
        system designed to run beyond year 2038, with a few remaining caveats:
      
         - All user space must be compiled with a 64-bit time_t, which will be
           supported in the coming musl-1.2 and glibc-2.32 releases, along
           with installed kernel headers from linux-5.6 or higher.
      
         - Applications that use the system call interfaces directly need to
           be ported to use the time64 syscalls added in linux-5.1 in place of
           the existing system calls. This impacts most users of futex() and
           seccomp() as well as programming languages that have their own
           runtime environment not based on libc.
      
         - Applications that use a private copy of kernel uapi header files or
           their contents may need to update to the linux-5.6 version, in
           particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h,
           linux/elfcore.h, linux/sockios.h, linux/timex.h and
           linux/can/bcm.h.
      
         - A few remaining interfaces cannot be changed to pass a 64-bit
           time_t in a compatible way, so they must be configured to use
           CLOCK_MONOTONIC times or (with a y2106 problem) unsigned 32-bit
           timestamps. Most importantly this impacts all users of 'struct
           input_event'.
      
         - All y2038 problems that are present on 64-bit machines also apply
           to 32-bit machines. In particular this affects file systems with
           on-disk timestamps using signed 32-bit seconds: ext4 with
           ext3-style small inodes, ext2, xfs (to be fixed soon) and ufs"

      Linus Torvalds authored
      Pull openat2 support from Al Viro:
       "This is the openat2() series from Aleksa Sarai.
      
        I'm afraid that the rest of namei stuff will have to wait - it got
        zero review the last time I'd posted #work.namei, and there had been a
        leak in the posted series I'd caught only last weekend. I was going to
        repost it on Monday, but the window opened and the odds of getting any
        review during that... Oh, well.
      
        Anyway, openat2 part should be ready; that _did_ get sane amount of
        review and public testing, so here it comes"
      
      From Aleksa's description of the series:
       "For a very long time, extending openat(2) with new features has been
        incredibly frustrating. This stems from the fact that openat(2) is
        possibly the most famous counter-example to the mantra "don't silently
        accept garbage from userspace" -- it doesn't check whether unknown
        flags are present[1].
      
        This means that (generally) the addition of new flags to openat(2) has
        been fraught with backwards-compatibility issues (O_TMPFILE has to be
        defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
        kernels gave errors, since it's insecure to silently ignore the
        flag[2]). All new security-related flags therefore have a tough road
        to being added to openat(2).
      
        Furthermore, the need for some sort of control over VFS's path
        resolution (to avoid malicious paths resulting in inadvertent
        breakouts) has been a very long-standing desire of many userspace
        applications.
      
        This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset
        (which was a variant of David Drysdale's O_BENEATH patchset[4] which
        was a spin-off of the Capsicum project[5]) with a few additions and
        changes made based on the previous discussion within [6] as well as
        others I felt were useful.
      
        In line with the conclusions of the original discussion of
        AT_NO_JUMPS, the flag has been split up into separate flags. However,
        instead of being an openat(2) flag it is provided through a new
        syscall openat2(2) which provides several other improvements to the
        openat(2) interface (see the patch description for more details). The
        following new LOOKUP_* flags are added:
      
        LOOKUP_NO_XDEV:
      
           Blocks all mountpoint crossings (upwards, downwards, or through
           absolute links). Absolute pathnames alone in openat(2) do not
           trigger this. Magic-link traversal which implies a vfsmount jump is
           also blocked (though magic-link jumps on the same vfsmount are
           permitted).
      
        LOOKUP_NO_MAGICLINKS:
      
           Blocks resolution through /proc/$pid/fd-style links. This is done
           by blocking the usage of nd_jump_link() during resolution in a
           filesystem. The term "magic-links" is used to match with the only
           reference to these links in Documentation/, but I'm happy to change
           the name.
      
           It should be noted that this is different to the scope of
           ~LOOKUP_FOLLOW in that it applies to all path components. However,
           you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
           will *not* fail (assuming that no parent component was a
           magic-link), and you will have an fd for the magic-link.
      
           In order to correctly detect magic-links, the introduction of a new
           LOOKUP_MAGICLINK_JUMPED state flag was required.
      
        LOOKUP_BENEATH:
      
           Disallows escapes to outside the starting dirfd's
           tree, using techniques such as ".." or absolute links. Absolute
           paths in openat(2) are also disallowed.
      
           Conceptually this flag is to ensure you "stay below" a certain
           point in the filesystem tree -- but this requires some additional
           to protect against various races that would allow escape using
           "..".
      
           Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
           can trivially beam you around the filesystem (breaking the
           protection). In future, there might be similar safety checks done
           as in LOOKUP_IN_ROOT, but that requires more discussion.
      
        In addition, two new flags are added that expand on the above ideas:
      
        LOOKUP_NO_SYMLINKS:
      
           Does what it says on the tin. No symlink resolution is allowed at
           all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this
           can still be used with NOFOLLOW to open an fd for the symlink as
           long as no parent path had a symlink component.
      
        LOOKUP_IN_ROOT:
      
           This is an extension of LOOKUP_BENEATH that, rather than blocking
           attempts to move past the root, forces all such movements to be
           scoped to the starting point. This provides chroot(2)-like
           protection but without the cost of a chroot(2) for each filesystem
           operation, as well as being safe against race attacks that
           chroot(2) is not.
      
           If a race is detected (as with LOOKUP_BENEATH) then an error is
           generated, and similar to LOOKUP_BENEATH it is not permitted to
           cross magic-links with LOOKUP_IN_ROOT.
      
           The primary need for this is from container runtimes, which
           currently need to do symlink scoping in userspace[7] when opening
           paths in a potentially malicious container.
      
           There is a long list of CVEs that could have bene mitigated by
           having RESOLVE_THIS_ROOT (such as CVE-2017-1002101,
           CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a
           few).
      
        In order to make all of the above more usable, I'm working on
        libpathrs[8] which is a C-friendly library for safe path resolution.
        It features a userspace-emulated backend if the kernel doesn't support
        openat2(2). Hopefully we can get userspace to switch to using it, and
        thus get openat2(2) support for free once it's ready.
      
        Future work would include implementing things like
        RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow
        programs to be sure they don't hit DoSes though stale NFS handles)"

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.6 kernel cycle.
      
        This is a pretty calm cycle so far, nothing special going on really.
        Some more changes will come in from the irqchip and pin control trees.
      
        I also deleted an orphan include file for FMC that was dangling since
        subsystem was removed.
      
        Core changes:
      
         - Document the usecases for the kernelspace vs userspace handling of
           GPIOs.
      
         - Handle MSI (message signalled interrupts) properly in the core
           hierarchical irqdomain code.
      
         - Fix a rare race condition while initializing the descriptor array.
      
        New drivers:
      
         - Xylon LogiCVC GPIO driver.
      
         - WDC934x GPIO controller driver.
      
        Driver improvements:
      
         - Implemented suspend/resume in the Tegra driver.
      
         - MPC8xx edge detection fixup.
      
         - Properly convert ThunderX to use hierarchical irqdomain with
           GPIOLIB_IRQCHIP on top of the revert of the previous buggy
           switchover. This time it works (hopefully).

       "Two new features - measuring certificates and querying IMA for a file
        hash - and three bug fixes:
      
         - Measuring certificates is like the rest of IMA, based on policy,
           but requires loading a custom policy. Certificates loaded onto a
           keyring, for example during early boot, before a custom policy has
           been loaded, are queued and only processed after loading the custom
           policy.
      
         - IMA calculates and caches files hashes. Other kernel subsystems,
           and possibly kernel modules, are interested in accessing these
           cached file hashes.
      
        The bug fixes prevent classifying a file short read (e.g. shutdown) as
        an invalid file signature, add a missing blank when displaying the
        securityfs policy rules containing LSM labels, and, lastly, fix the
        handling of the IMA policy information for unknown LSM labels"

      Pull sound updates from Takashi Iwai:
       "As the diffstat shows we've had again a lot of works done for this
        cycle: the majority of changes are the continued componentization and
        code refactoring in ASoC, the tree-wide PCM API updates and cleanups
        and SOF updates while a few ASoC driver updates are seen, too.
      
        Here we go, some highlights:
      
        Core:
         - Finally y2038 support landed to ALSA ABI; some ioctls have been
           extended and lots of tricks were applied
         - Applying the new managed PCM buffer API to all drivers; the API
           itself was already merged in 5.5
         - The already deprecated dimension support in ALSA control API is
           dropped completely now
         - Verification of ALSA control elements to catch API misuses
      
        ASoC:
         - Further code refactorings and moving things to the component level
         - Lots of updates and improvements on SOF / Intel drivers; now
           including common HDMI driver and SoundWire support
         - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
           WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
           RT1015 and RT1308
      
        HD-audio:
         - Improved ring-buffer communications using waitqueue
         - Drop the superfluous buffer preallocation on x86
      
        Others:
         - Many code cleanups, mostly constifications over the whole tree
         - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
         - FireWire: code refactoring for oxfw and dice drivers"

         provided via a keyring key.
      
       - Prepare for the new dirhash method (SipHash of plaintext name) that
         will be used by directories that are both encrypted and casefolded.
      
       - Switch to a new format for "no-key names" that prepares for the new
         dirhash method, and also fixes a longstanding bug where multiple
         filenames could map to the same no-key name.
      
       - Allow the crypto algorithms used by fscrypt to be built as loadable
         modules when the fscrypt-capable filesystems are.
      
       - Optimize fscrypt_zeroout_range().
      
       - Various cleanups.

      Pull btrfs updates from David Sterba:
       "Features, highlights:
      
         - async discard
             - "mount -o discard=async" to enable it
             - freed extents are not discarded immediatelly, but grouped
               together and trimmed later, with IO rate limiting
             - the "sync" mode submits short extents that could have been
               ignored completely by the device, for SATA prior to 3.1 the
               requests are unqueued and have a big impact on performance
             - the actual discard IO requests have been moved out of
               transaction commit to a worker thread, improving commit latency
             - IO rate and request size can be tuned by sysfs files, for now
               enabled only with CONFIG_BTRFS_DEBUG as we might need to
               add/delete the files and don't have a stable-ish ABI for
               general use, defaults are conservative
      
         - export device state info in sysfs, eg. missing, writeable
      
         - no discard of extents known to be untouched on disk (eg. after
           reservation)
      
         - device stats reset is logged with process name and PID that called
           the ioctl
      
        Fixes:
      
         - fix missing hole after hole punching and fsync when using NO_HOLES
      
         - writeback: range cyclic mode could miss some dirty pages and lead
           to OOM
      
         - two more corner cases for metadata_uuid change after power loss
           during the change
      
         - fix infinite loop during fsync after mix of rename operations
      
        Core changes:
      
         - qgroup assign returns ENOTCONN when quotas not enabled, used to
           return EINVAL that was confusing
      
         - device closing does not need to allocate memory anymore
      
         - snapshot aware code got removed, disabled for years due to
           performance problems, reimplmentation will allow to select wheter
           defrag breaks or does not break COW on shared extents
      
         - tree-checker:
             - check leaf chunk item size, cross check against number of
               stripes
             - verify location keys for DIR_ITEM, DIR_INDEX and XATTR items
      
         - new self test for physical -> logical mapping code, used for super
           block range exclusion
      
         - assertion helpers/macros updated to avoid objtool "unreachable
           code" reports on older compilers or config option combinations"

      selftests/ftrace: fix glob selftest · af4ddd60
      Sven Schnelle authored
      test.d/ftrace/func-filter-glob.tc is failing on s390 because it has
      ARCH_INLINE_SPIN_LOCK and friends set to 'y'. So the usual
      __raw_spin_lock symbol isn't in the ftrace function list. Change
      '*aw*lock' to '*spin*lock' which would hopefully match some of the
      locking functions on all platforms.
