      cifs: smbd: Indicate to retry on transport sending failure · 62fdf670
      Long Li authored
      Failure to send a packet doesn't mean it's a permanent failure, it can't be
      returned to user process. This I/O should be retried or failed based on
      server packet response and transport health. This logic is handled by the
      upper layer.
      
      Give this decision to upper layer.

      smbd: Make upper layer decide when to destroy the transport · 050b8c37
      Long Li authored
      On transport recoonect, upper layer CIFS code destroys the current
      transport and then recoonect. This code path is not used by SMBD, in that
      SMBD destroys its transport on RDMA disconnect notification independent of
      CIFS upper layer behavior.
      
      This approach adds some costs to SMBD layer to handle transport shutdown
      and restart, and to deal with several racing conditions on reconnecting
      transport.
      
      Re-work this code path by introducing a new smbd_destroy. This function is
      called form upper layer to ask SMBD to destroy the transport. SMBD will no
      longer need to destroy the transport by itself while worrying about data
      transfer is in progress. The upper layer guarantees the transport is
      locked.

      CIFS: check CIFS_MOUNT_NO_DFS when trying to reuse existing sb · d070f9dd
      Aurelien Aptel authored
      if we mount A then mount A again with nodfs, we shouldn't reuse the
      superblock. document the purpose of the defines as well.
      
      there are most likely more flags that needs to be added to this mask,
      in fact the logic to find them should be which flag should
      be *ignored* when trying to reuse an existing sb.

      cifs: Fix DFS cache refresher for DFS links · 5072010c
      Paulo Alcantara (SUSE) authored
      As per MS-DFSC, when a DFS cache entry is expired and it is a DFS
      link, then a new DFS referral must be sent to root server in order to
      refresh the expired entry.
      
      This patch ensures that all new DFS referrals for refreshing the cache
      are sent to DFS root.

      cifs: don't use __constant_cpu_to_le32() · f5307104
      Sergey Senozhatsky authored
      A trivial patch.
      
      cpu_to_le32() is capable enough to detect __builtin_constant_p()
      and to use an appropriate compile time ___constant_swahb32()
      function.
      
      So we can use cpu_to_le32() instead of __constant_cpu_to_le32().

         - The biggest change, and the source of all the arch/* changes, is
           the patchset from Dmitry to help enable some of the work he is
           doing around PTRACE_GET_SYSCALL_INFO.
      
           To be honest, including this in the audit tree is a bit of a
           stretch, but it does help move audit a little further along towards
           proper syscall auditing for all arches, and everyone else seemed to
           agree that audit was a "good" spot for this to land (or maybe they
           just didn't want to merge it? dunno.).

       "Here is the "real" big set of char/misc driver patches for 5.2-rc1
      
        Loads of different driver subsystem stuff in here, all over the places:
         - thunderbolt driver updates
         - habanalabs driver updates
         - nvmem driver updates
         - extcon driver updates
         - intel_th driver updates

         - fastrpc driver updates
         - other minor driver updates
         - chardev minor fixups
      
        Feels like this tree is getting to be a dumping ground of "small
        driver subsystems" these days. Which is fine with me, if it makes
        things easier for those subsystem maintainers.

       "Here is the big staging and iio driver update for 5.2-rc1.
      
        Lots of tiny fixes all over the staging and IIO driver trees here,
        along with some new IIO drivers.
      
        The "counter" subsystem was added in here as well, as it is needed by
        the IIO drivers and subsystem.
      
        Also we ended up deleting two drivers, making this pull request remove
        a few hundred thousand lines of code, always a nice thing to see. Both
        of the drivers removed have been replaced with "real" drivers in their
        various subsystem directories, and they will be coming to you from
        those locations during this merge window.
      
        There are some core vt/selection changes in here, that was due to some
        cleanups needed for the speakup fixes. Those have all been acked by
        the various subsystem maintainers (i.e. me), so those are ok.
      
        We also added a few new drivers, for some odd hardware, giving new
        developers plenty to work on with basic coding style cleanups to come
        in the near future.

      Pull Wimplicit-fallthrough updates from Gustavo A. R. Silva:
       "Mark switch cases where we are expecting to fall through.
      
        This is part of the ongoing efforts to enable -Wimplicit-fallthrough.
      
        Most of them have been baking in linux-next for a whole development
        cycle. And with Stephen Rothwell's help, we've had linux-next
        nag-emails going out for newly introduced code that triggers
        -Wimplicit-fallthrough to avoid gaining more of these cases while we
        work to remove the ones that are already present.
      
        We are getting close to completing this work. Currently, there are
        only 32 of 2311 of these cases left to be addressed in linux-next. I'm
        auditing every case; I take a look into the code and analyze it in
        order to determine if I'm dealing with an actual bug or a false
        positive, as explained here:
      
            https://lore.kernel.org/lkml/c2fad584-1705-a5f2-d63c-824e9b96cf50@embeddedor.com/
      
        While working on this, I've found and fixed the several missing
        break/return bugs, some of them introduced more than 5 years ago.
      
        Once this work is finished, we'll be able to universally enable
        "-Wimplicit-fallthrough" to avoid any of these kinds of bugs from
        entering the kernel again"

      Pull pidfd updates from Christian Brauner:
       "This patchset makes it possible to retrieve pidfds at process creation
        time by introducing the new flag CLONE_PIDFD to the clone() system
        call. Linus originally suggested to implement this as a new flag to
        clone() instead of making it a separate system call.
      
        After a thorough review from Oleg CLONE_PIDFD returns pidfds in the
        parent_tidptr argument. This means we can give back the associated pid
        and the pidfd at the same time. Access to process metadata information
        thus becomes rather trivial.
      
        As has been agreed, CLONE_PIDFD creates file descriptors based on
        anonymous inodes similar to the new mount api. They are made
        unconditional by this patchset as they are now needed by core kernel
        code (vfs, pidfd) even more than they already were before (timerfd,
        signalfd, io_uring, epoll etc.). The core patchset is rather small.
        The bulky looking changelist is caused by David's very simple changes
        to Kconfig to make anon inodes unconditional.
      
        A pidfd comes with additional information in fdinfo if the kernel
        supports procfs. The fdinfo file contains the pid of the process in
        the callers pid namespace in the same format as the procfs status
        file, i.e. "Pid:\t%d".
      
        To remove worries about missing metadata access this patchset comes
        with a sample/test program that illustrates how a combination of
        CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free
        access to process metadata through /proc/<pid>.
      
        Further work based on this patchset has been done by Joel. His work
        makes pidfds pollable. It finished too late for this merge window. I
        would prefer to have it sitting in linux-next for a while and send it
        for inclusion during the 5.3 merge window"

      Pull stream_open conversion from Kirill Smelkov:
      
       - remove unnecessary double nonseekable_open from drivers/char/dtlk.c
         as noticed by Pavel Machek while reviewing nonseekable_open ->
         stream_open mass conversion.
      
       - the mass conversion patch promised in commit 10dce8af ("fs:
         stream_open - opener for stream-like files so that read and write can
         run simultaneously without deadlock") and is automatically generated
         by running
      
              $ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci
      
         I've verified each generated change manually - that it is correct to
         convert - and each other nonseekable_open instance left - that it is
         either not correct to convert there, or that it is not converted due
         to current stream_open.cocci limitations. More details on this in the
         patch.
      
       - finally, change VFS to pass ppos=NULL into .read/.write for files
         that declare themselves streams. It was suggested by Rasmus Villemoes
         and makes sure that if ppos starts to be erroneously used in a stream
         file, such bug won't go unnoticed and will produce an oops instead of
         creating illusion of position change being taken into account.
      
         Note: this patch does not conflict with "fuse: Add FOPEN_STREAM to
         use stream_open()" that will be hopefully coming via FUSE tree,
         because fs/fuse/ uses new-style .read_iter/.write_iter, and for these
         accessors position is still passed as non-pointer kiocb.ki_pos .

      Pull xfs updates from Darrick Wong:
       "Here's a big pile of new stuff for XFS for 5.2. XFS has grown the
        ability to report metadata health status to userspace after online
        fsck checks the filesystem. The online metadata checking code is (I
        really hope) feature complete with the addition of checks for the
        global fs counters, though it'll remain EXPERIMENTAL for now.
      
        There are also fixes for thundering herds of writeback completions and
        some other deadlocks, fixes for theoretical integer overflow attacks
        on space accounting, and removal of the long-defunct 'mntpt' option
        which was deprecated in the mid-2000s and (it turns out) totally
        broken since 2011 (and nobody complained...).
      
        Summary:
      
         - Fix some more buffer deadlocks when performing an unmount after a
           hard shutdown.
      
         - Fix some minor space accounting issues.
      
         - Fix some use after free problems.
      
         - Make the (undocumented) FITRIM behavior consistent with other
           filesystems.
      
         - Embiggen the xfs geometry ioctl's data structure.
      
         - Introduce a new AG geometry ioctl.
      
         - Introduce a new online health reporting infrastructure and ioctl
           for userspace to query a filesystem's health status.
      
         - Enhance online scrub and repair to update the health reports.
      
         - Reduce thundering herd problems when writeback io completes.
      
         - Fix some transaction reservation type errors.
      
         - Fix integer overflow problems with delayed alloc reservation
           counters.
      
         - Fix some problems where we would exit to userspace without
           unlocking.
      
         - Fix inconsistent behavior when finishing deferred ops fails.
      
         - Strengthen scrub to check incore data against ondisk metadata.
      
         - Remove long-broken mntpt mount option.
      
         - Add an online scrub function for the filesystem summary counters,
           which should make online metadata scrub more or less feature
           complete for now.

      Pull btrfs updates from David Sterba:
       "This time the majority of changes are cleanups, though there's still a
        number of changes of user interest.
      
        User visible changes:
      
         - better read time and write checks to catch errors early and before
           writing data to disk (to catch potential memory corruption on data
           that get checksummed)
      
         - qgroups + metadata relocation: last speed up patch int the series
           to address the slowness, there should be no overhead comparing
           balance with and without qgroups
      
         - FIEMAP ioctl does not start a transaction unnecessarily, this can
           result in a speed up and less blocking due to IO
      
         - LOGICAL_INO (v1, v2) does not start transaction unnecessarily, this
           can speed up the mentioned ioctl and scrub as well
      
         - fsync on files with many (but not too many) hardlinks is faster,
           finer decision if the links should be fsynced individually or
           completely
      
         - send tries harder to find ranges to clone
      
         - trim/discard will skip unallocated chunks that haven't been touched
           since the last mount
      
        Fixes:
      
         - send flushes delayed allocation before start, otherwise it could
           miss some changes in case of a very recent rw->ro switch of a
           subvolume
      
         - fix fallocate with qgroups that could lead to space accounting
           underflow, reported as a warning
      
         - trim/discard ioctl honours the requested range
      
         - starting send and dedupe on a subvolume at the same time will let
           only one of them succeed, this is to prevent changes that send
           could miss due to dedupe; both operations are restartable
      
        Core changes:
      
         - more tree-checker validations, errors reported by fuzzing tools:
            - device item
            - inode item
            - block group profiles
      
         - tracepoints for extent buffer locking
      
         - async cow preallocates memory to avoid errors happening too deep in
           the call chain
      
         - metadata reservations for delalloc reworked to better adapt in
           many-writers/low-space scenarios
      
         - improved space flushing logic for intense DIO vs buffered workloads
      
         - lots of cleanups
            - removed unused struct members
            - redundant argument removal
            - properties and xattrs
            - extent buffer locking
            - selftests

        In addition, this optimization makes kernel_fpu_begin() cheaper by
        requiring registers saving only on the first invocation and skipping
        that in following ones.

        the already complex FPU code, hopefully making it more palatable for

      Pull HID updates from Jiri Kosina:
      
       - support for U2F Zero device, from Andrej Shadura
      
       - logitech-dj has historically been treating devices behind
         non-unifying receivers as generic devices, using the HID emulation in
         the receiver. That had several shortcomings (special keys handling,
         battery level monitoring, etc). The driver has been reworked to
         enumarate (and directly communicate with) the devices behind the
         receiver, to avoid the (too) generic HID implementation in the
         receiver itself. All the work done by Benjamin Tissoires and Hans de
         Goede.
      
       - restructuring of intel-ish driver in order to allow for multiple
         clients of the ISH implementation, from Srinivas Pandruvada
      
       - several other smaller fixes and assorted device ID additions
