      Linus Torvalds authored
      Pull xfs updates from Darrick Wong:
       "This cycle we've worked on fixing bugs and improving XFS' memory
        footprint.
      
        The most notable fixes include: fixing a corruption warning (and free
        space accounting skew) if copy on write fails; fixing slab cache
        misuse if SLOB is enabled, which apparently was broken for years
        without anybody noticing; and fixing a potential race with online
        shrinkfs.
      
        Otherwise, the bulk of the changes here involve setting up separate
        slab caches for frequently used items such as btree cursors and log
        intent items, and compacting the structures to reduce memory usage of
        those items substantially. This also sets us up to support larger
        btrees in future kernels. We also switch parts of online fsck to
        allocate scrub context information from the heap instead of using
        stack space.
      
        Summary:
      
         - Bug fixes and cleanups for kernel memory allocation usage, this
           time without touching the mm code.
      
         - Refactor the log recovery mechanism that preserves held resources
           across a transaction roll so that it uses the exact same mechanism
           that we use for that during regular runtime.
      
         - Fix bugs and tighten checking around btree heights.
      
         - Remove more old typedefs.
      
         - Fix perag reference leaks when racing with growfs.
      
         - Remove unused fields from xfs_btree_cur.
      
         - Allocate various scrub structures on the heap to reduce stack
           usage.
      
         - Pack xfs_btree_cur fields and rearrange to support arbitrary
           heights.
      
         - Compute maximum possible heights for each btree height, and use
           that to set up slab caches for each btree type.
      
         - Finally remove kmem_zone_t, since these have always been struct
           kmem_cache on Linux.
      
         - Compact the structures used to coordinate work intent items.
      
         - Set up slab caches for each work intent item type.
      
         - Rename the "bmap_add_free" function to "free_extent_later", which
           more accurately describes what it does.
      
         - Fix corruption warning on unmount when a CoW preallocation covers a
           data fork delalloc reservation but then the CoW fails.
      
         - Add some more minor code improvements"

      Pull gfs2 mmap + page fault deadlocks fixes from Andreas Gruenbacher:
       "Functions gfs2_file_read_iter and gfs2_file_write_iter are both
        accessing the user buffer to write to or read from while holding the
        inode glock.
      
        In the most basic deadlock scenario, that buffer will not be resident
        and it will be mapped to the same file. Accessing the buffer will
        trigger a page fault, and gfs2 will deadlock trying to take the same
        inode glock again while trying to handle that fault.
      
        Fix that and similar, more complex scenarios by disabling page faults
        while accessing user buffers. To make this work, introduce a small
        amount of new infrastructure and fix some bugs that didn't trigger so

      afs: Set mtime from the client for yfs create operations · 52af7105
      Marc Dionne authored
      For operations that create vnodes on the server such as CreateFile,
      MakeDir or Symlink, the server will store its own current time as
      the mtime if the client doesn't pass in a time in the accompanying
      StoreStatus structure.
      
      If the server and client clocks are not well synchronized, the client
      may see timestamps in the future or inconsistent dependency checks
      with "make" for files that are not modified after creation:
      
      make[2]: Warning: File 'arch/x86/kernel/apic/modules.order' has
      modification time 0.14 s in the future
      make[2]: warning:  Clock skew detected.  Your build may be incomplete.
      
      This is already handled correctly for non yfs operations; also
      set the mtime for the corresponding yfs operations.
      
      Changes:
      v3: Replace S_IRWXUGO with 0777, per checkpatch
      v2: [dhowells] Merge the two xdr_encode_YFSStoreStatus*() functions together

      Pull selinux updates from Paul Moore:
      
       - Add LSM/SELinux/Smack controls and auditing for io-uring.
      
         As usual, the individual commit descriptions have more detail, but we
         were basically missing two things which we're adding here:
      
            + establishment of a proper audit context so that auditing of
              io-uring ops works similarly to how it does for syscalls (with
              some io-uring additions because io-uring ops are *not* syscalls)
      
            + additional LSM hooks to enable access control points for some of
              the more unusual io-uring features, e.g. credential overrides.
      
         The additional audit callouts and LSM hooks were done in conjunction
         with the io-uring folks, based on conversations and RFC patches
         earlier in the year.
      
       - Fixup the binder credential handling so that the proper credentials
         are used in the LSM hooks; the commit description and the code
         comment which is removed in these patches are helpful to understand
         the background and why this is the proper fix.
      
       - Enable SELinux genfscon policy support for securityfs, allowing
         improved SELinux filesystem labeling for other subsystems which make
         use of securityfs, e.g. IMA.
