    SUNRPC: Add a helper rpcauth_lookup_generic_cred() · 98a8e323
    Trond Myklebust authored
    The NFSv4 protocol allows clients to negotiate security protocols on the
    fly in the case where an administrator on the server changes the export
    settings and/or in the case where we may have a filesystem migration event.
    
    Instead of having the NFS client code cache credentials that are tied to a
    particular AUTH method it is therefore preferable to have a generic credential
    that can be converted into whatever AUTH is in use by the RPC client when
    the read/write/sillyrename/... is put on the wire.
    
    We do this by means of the new "generic" credential, which basically just
    caches the minimal information that is needed to look up an RPCSEC_GSS,
    AUTH_SYS, or AUTH_NULL credential.
