  • a40dc6cc2   ceph: enable/disable dentry complete flags via mount option ... Browse Code »

    Enable/disable use of the dentry dir 'complete' flag via a mount option.
    This lets the admin control whether ceph uses the dcache to satisfy
    negative lookups or readdir when it has the entire directory contents in
    its cache.

    This is purely a performance optimization; correctness is guaranteed
    whether it is enabled or not.

  • d46cfba53   ceph: always initialize the dentry in open_root_dentry() ... Browse Code »

    When open_root_dentry() gets a dentry via d_obtain_alias() it does
    not get initialized. If the dentry obtained came from the cache,
    this is OK. But if not, the result is an improperly initialized
    dentry.

    To fix this, call ceph_init_dentry() regardless of which path
    produced the dentry. That function returns immediately for a dentry
    that is already initialized, it is safe to use either way.

    (Credit to Sage, who suggested this fix.)

  • 774ac21da   ceph: initialize root dentry ... Browse Code »

    Set up d_fsdata on the root dentry. This fixes a NULL pointer dereference
    in ceph_d_prune on umount. It also means we can eventually strip out all
    of the conditional checks on d_fsdata because it is now set unconditionally
    (prior to setting up the d_ops).

    Fix the ceph_d_prune debug print while we're here.

  • 14303d20f   ceph: implement DIRLAYOUTHASH feature to get dir layout from MDS ... Browse Code »

    This implements the DIRLAYOUTHASH protocol feature, which passes the dir
    layout over the wire from the MDS. This gives the client knowledge
    of the correct hash function to use for mapping dentries among dir
    fragments.

    Note that if this feature is _not_ present on the client but is on the
    MDS, the client may misdirect requests. This will result in a forward
    and degrade performance. It may also result in inaccurate NFS filehandle
    generation, which will prevent fh resolution when the inode is not present
    in the client cache and the parent directories have been fragmented.

  • 3d14c5d2b   ceph: factor out libceph from Ceph file system ... Browse Code »

    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.

  • 558d3499b   ceph: fix f_namelen reported by statfs ... Browse Code »

    We were setting f_namelen in kstatfs to PATH_MAX instead of NAME_MAX.
    That disagrees with ceph_lookup behavior (which checks against NAME_MAX),
    and also makes the pjd posix test suite spit out ugly errors because with
    can't clean up its temporary files.

  • a922d38fd   ceph: close out mds, osd connections before stopping auth ... Browse Code »

    The auth module (part of the mon_client) is needed to free any
    ceph_authorizer(s) used by the mds and osd connections. Flush the msgr
    workqueue before stopping monc to ensure that the destroy_authorizer
    auth op is available when those connections are closed out.

  • 7e34bc524   fs/ceph: Use ERR_CAST ... Browse Code »

    Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)). The former makes more
    clear what is the purpose of the operation, which otherwise looks like a
    no-op.

    In the case of fs/ceph/inode.c, ERR_CAST is not needed, because the type of
    the returned value is the same as the type of the enclosing function.

    The semantic patch that makes this change is as follows:
    (http://coccinelle.lip6.fr/)

    //
    @@
    type T;
    T x;
    identifier f;
    @@

    T f (...) { }

    @@
    expression x;
    @@

    - ERR_PTR(PTR_ERR(x))
    + ERR_CAST(x)
