    Could you elaborate a bit more on the design of this patch?  While LSM should
    support MLS label style modules, the MLS label concepts themselves should not
    be embedded into the LSM interface.  From the above description, it is
    unclear whether the patch is specific to the notions of label dominance, or
    if it is generic to inspecting security blobs when subjects attempt to
    read/write attributes of other subjects.

    P.S.  You appear to be posting from an address that is not subscribed to the
    LSM mailing list.  This is fine, but introduces an arbitrary amount of delay
    until I get around to approving the post.
