  • Adding support for fscache to the Ceph filesystem. This would bring it to on
    par with some of the other network filesystems in Linux (like NFS, AFS, etc...)

    In order to mount the filesystem with fscache the 'fsc' mount option must be
    passed.

  • Remove the if and else conditional because the code is in mainline and there
    is no need in it being there.

    Also, Changed Makefile to use -y instead of -objs
    because -objs is deprecated and not mentioned in
    Documentation/kbuild/makefiles.txt.

  • 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.

  • Implement flock inode operation to support advisory file locking. All
    lock/unlock operations are synchronous with the MDS. Lock state is
    sent when reconnecting to a recovering MDS to restore the shared lock
    state.

  • 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.

  • 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.

  • 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.
