      [PATCH] Generic VFS fallback for security xattrs · f549d6c1
      Stephen Smalley authored
      
      
      This patch modifies the VFS setxattr, getxattr, and listxattr code to fall
      back to the security module for security xattrs if the filesystem does not
      support xattrs natively.  This allows security modules to export the incore
      inode security label information to userspace even if the filesystem does
      not provide xattr storage, and eliminates the need to individually patch
      various pseudo filesystem types to provide such access.  The patch removes
      the existing xattr code from devpts and tmpfs as it is then no longer
      needed.
      
      The patch restructures the code flow slightly to reduce duplication between
      the normal path and the fallback path, but this should only have one
      user-visible side effect - a program may get -EACCES rather than
      -EOPNOTSUPP if policy denied access but the filesystem didn't support the
      operation anyway.  Note that the post_setxattr hook call is not needed in
      the fallback case, as the inode_setsecurity hook call handles the incore
      inode security state update directly.  In contrast, we do call fsnotify in
      both cases.

      [PATCH] shmem_populate: avoid an useless check, and some comments · d44ed4f8
      Paolo 'Blaisorblade' Giarrusso authored
      
      
      Either shmem_getpage returns a failure, or it found a page, or it was told
      it couldn't do any I/O.  So it's useless to check nonblock in the else
      branch.  We could add a BUG() there but I preferred to comment the
      offending function.
      
      This was taken out from one Ingo Molnar's old patch I'm resurrecting.

      Fix nasty ncpfs symlink handling bug. · cc314eef
      Linus Torvalds authored
      
      
      This bug could cause oopses and page state corruption, because ncpfs
      used the generic page-cache symlink handlign functions.  But those
      functions only work if the page cache is guaranteed to be "stable", ie a
      page that was installed when the symlink walk was started has to still
      be installed in the page cache at the end of the walk.
      
      We could have fixed ncpfs to not use the generic helper routines, but it
      is in many ways much cleaner to instead improve on the symlink walking
      helper routines so that they don't require that absolute stability.
      
      We do this by allowing "follow_link()" to return a error-pointer as a
      cookie, which is fed back to the cleanup "put_link()" routine.  This
      also simplifies NFS symlink handling.

      [PATCH] shmem: restore superblock info · 0edd73b3
      Hugh Dickins authored
      
      
      To improve shmem scalability, we allowed tmpfs instances which don't need
      their blocks or inodes limited not to count them, and not to allocate any
      sbinfo.  Which was okay when the only use for the sbinfo was accounting
      blocks and inodes; but since then a couple of unrelated projects extending
      tmpfs want to store other data in the sbinfo.  Whether either extension
      reaches mainline is beside the point: I'm guilty of a bad design decision,
      and should restore sbinfo to make any such future extensions easier.
      
      So, once again allocate a shmem_sb_info for every shmem/tmpfs instance, and
      now let max_blocks 0 indicate unlimited blocks, and max_inodes 0 unlimited
      inodes.  Brent Casavant verified (many months ago) that this does not
      perceptibly impact the scalability (since the unlimited sbinfo cacheline is
      repeatedly accessed but only once dirtied).
      
      And merge shmem_set_size into its sole caller shmem_remount_fs.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
