      There are multiple ingredients for this:
      
       1) PAGE_NONE is defined to _CACHE_CACHABLE_NONCOHERENT, which is CCA 3
          on all platforms except SB1 where it's CCA 5.
       2) _page_cachable_default must have bits set which are not set
          _CACHE_CACHABLE_NONCOHERENT.
       3) Either the defective version of pte_modify for XPA or the standard
          version must be in used.  However pte_modify for the 36 bit address
          space support is no affected.
      
      In that case additional bits in the final CCA mode may generate an invalid
      value for the CCA field.  On the R10000 system where this was tracked
      down for example a CCA 7 has been observed, which is Uncached Accelerated.
      
      Fixed by:
      
       1) Using the proper CCA mode for PAGE_NONE just like for all the other
          PAGE_* pte/pmd bits.
       2) Fix the two affected variants of pte_modify.
      
      Further code inspection also shows the same issue to exist in pmd_modify
      which would affect huge page systems.
      
      Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE
      and pmd_modify issue found by me.
      
      The history of this goes back beyond Linus' git history.  Chris Dearman's
      commit 35133692 ("[MIPS] Allow setting of
      the cache attribute at run time.") missed the opportunity to fix this
      but it was originally introduced in lmo commit
      d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.")
      and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option
      CONFIG_MIPS_UNCACHED.")

      locks: use file_inode() · 6343a212
      Miklos Szeredi authored
      (Another one for the f_path debacle.)
      
      ltp fcntl33 testcase caused an Oops in selinux_file_send_sigiotask.
      
      The reason is that generic_add_lease() used filp->f_path.dentry->inode
      while all the others use file_inode().  This makes a difference for files
      opened on overlayfs since the former will point to the overlay inode the
      latter to the underlying inode.
      
      So generic_add_lease() added the lease to the overlay inode and
      generic_delete_lease() removed it from the underlying inode.  When the file
      was released the lease remained on the overlay inode's lock list, resulting
      in use after free.

      namespace: update event counter when umounting a deleted dentry · e06b933e
      Andrey Ulanov authored
      - m_start() in fs/namespace.c expects that ns->event is incremented each
        time a mount added or removed from ns->list.
      - umount_tree() removes items from the list but does not increment event
        counter, expecting that it's done before the function is called.
      - There are some codepaths that call umount_tree() without updating
        "event" counter. e.g. from __detach_mounts().
      - When this happens m_start may reuse a cached mount structure that no
        longer belongs to ns->list (i.e. use after free which usually leads
        to infinite loop).
      
      This change fixes the above problem by incrementing global event counter
      before invoking umount_tree().

      9p: use file_dentry() · b403f0e3
      Miklos Szeredi authored
      v9fs may be used as lower layer of overlayfs and accessing f_path.dentry
      can lead to a crash.  In this case it's a NULL pointer dereference in
      p9_fid_create().
      
      Fix by replacing direct access of file->f_path.dentry with the
      file_dentry() accessor, which will always return a native object.

      lockd: unregister notifier blocks if the service fails to come up completely · cb7d224f
      Scott Mayhew authored
      If the lockd service fails to start up then we need to be sure that the
      notifier blocks are not registered, otherwise a subsequent start of the
      service could cause the same notifier to be registered twice, leading to
      soft lockups.

       "Contained are some standard fixes and unusually an extension to the
        Reset API.  Some of those changes are required to fix a bug introduced
        in -rc1, which introduces extra 'reset line checks' i.e. whether the
        line is shared or not.  If a line is shared and the new *_shared() API
        is not used, the request fails with an error.  This breaks USB in v4.7
        for ST's platforms.
      
        Admittedly, there are some patches contained in our (MFD/Reset)
        immutable branch which are not true -fixes, but there isn't anything I
        can do about that.  Rest assured though, there aren't any API
        'changes'.  Everything is the same from the consumer's perspective.
      
         - Use new reset_*_get_shared() variant to prevent reset line
