      ceph: fix file mode calculation · 38be7a79
      Sage Weil authored
      open(2) must always include one of O_RDONLY, O_WRONLY, or O_RDWR.  No need
      for any O_APPEND special case.
      
      Passing O_WRONLY|O_RDWR is undefined according to the man page, but the
      Linux VFS interprets this as O_RDWR, so we'll do the same.
      
      This fixes open(2) with flags O_RDWR|O_APPEND, which was incorrectly being
      translated to readonly.

      ceph: factor out libceph from Ceph file system · 3d14c5d2
      Yehuda Sadeh authored
      This factors out protocol and low-level storage parts of ceph into a
      separate libceph module living in net/ceph and include/linux/ceph.  This
      is mostly a matter of moving files around.  However, a few key pieces
      of the interface change as well:
      
       - ceph_client becomes ceph_fs_client and ceph_client, where the latter
         captures the mon and osd clients, and the fs_client gets the mds client
         and file system specific pieces.
       - Mount option parsing and debugfs setup is correspondingly broken into
         two pieces.
       - The mon client gets a generic handler callback for otherwise unknown
         messages (mds map, in this case).
       - The basic supported/required feature bits can be expanded (and are by
         ceph_fs_client).
      
      No functional change, aside from some subtle error handling cases that got
      cleaned up in the refactoring process.

      ceph: on-wire types · 0dee3c28
      Sage Weil authored
      These headers describe the types used to exchange messages between the
      Ceph client and various servers.  All types are little-endian and
      packed.  These headers are shared between the kernel and userspace, so
      all types are in terms of e.g. __u32.
      
      Additionally, we define a few magic values to identify the current
      version of the protocol(s) in use, so that discrepancies to be
      detected on mount.
