      posix_acl: de-union a_refcount and a_rcu · 6d4e56ce
      Jeff Layton authored
      Currently the two are unioned together, but I don't think that's safe.
      It looks like get_cached_acl could race with the last put in
      posix_acl_release. get_cached_acl calls atomic_inc_not_zero on
      a_refcount, but that field could have already been clobbered by
      call_rcu, and may no longer be zero. Fix this by de-unioning the two

      tmpfs: fix regression hang in fallocate undo · 7f556567
      Hugh Dickins authored
      The well-spotted fallocate undo fix is good in most cases, but not when
      fallocate failed on the very first page.  index 0 then passes lend -1
      to shmem_undo_range(), and that has two bad effects: (a) that it will
      undo every fallocation throughout the file, unrestricted by the current
      range; but more importantly (b) it can cause the undo to hang, because
      lend -1 is treated as truncation, which makes it keep on retrying until
      every page has gone, but those already fully instantiated will never go
      away.  Big thank you to xfstests generic/269 which demonstrates this.
      Fixes: b9b4bb26 ("tmpfs: don't undo fallocate past its last page")

      Revert "ecryptfs: forbid opening files without mmap handler" · 78c4e172
      Jeff Mahoney authored
      This reverts commit 2f36db71.
      It fixed a local root exploit but also introduced a dependency on
      the lower file system implementing an mmap operation just to open a file,
      which is a bit of a heavy hammer.  The right fix is to have mmap depend
      on the existence of the mmap handler instead.

      Pull block IO fixes from Jens Axboe:
       "Three small fixes that have been queued up and tested for this series:
         - A bug fix for xen-blkfront from Bob Liu, fixing an issue with
           incomplete requests during migration.
         - A fix for an ancient issue in retrieving the IO priority of a
           different PID than self, preventing that task from going away while
           we access it.  From Omar.
         - A writeback fix from Tahsin, fixing a case where we'd call ihold()
           with a zero ref count inode"
      * 'for-linus' of git://git.kernel.dk/linux-block:
        block: fix use-after-free in sys_ioprio_get()
