      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: add support for auth_x authentication protocol · ec0994e4
      Sage Weil authored
      The auth_x protocol implements support for a kerberos-like mutual
      authentication infrastructure used by Ceph.  We do not simply use vanilla
      kerberos because of scalability and performance issues when dealing with
      a large cluster of nodes providing a single logical service.
      
      Auth_x provides mutual authentication of client and server and protects
      against replay and man in the middle attacks.  It does not encrypt
      the full session over the wire, however, so data payload may still be
      snooped.

      ceph: support ceph_pagelist for message payload · 58bb3b37
      Sage Weil authored
      The ceph_pagelist is a simple list of whole pages, strung together via
      their lru list_head.  It facilitates encoding to a "buffer" of unknown
      size.  Allow its use in place of the ceph_msg page vector.
      
      This will be used to fix the huge buffer preallocation woes of MDS
      reconnection.

      ceph: negotiate authentication protocol; implement AUTH_NONE protocol · 4e7a5dcd
      Sage Weil authored
      When we open a monitor session, we send an initial AUTH message listing
      the auth protocols we support, our entity name, and (possibly) a previously
      assigned global_id.  The monitor chooses a protocol and responds with an
      initial message.
      
      Initially implement AUTH_NONE, a dummy protocol that provides no security,
      but works within the new framework.  It generates 'authorizers' that are
      used when connecting to (mds, osd) services that simply state our entity
      name and global_id.
      
      This is a wire protocol change.
