    nfsd: add support for upcall version 2 · 6ee95d1c
    Scott Mayhew authored
    Version 2 upcalls will allow the nfsd to include a hash of the kerberos
    principal string in the Cld_Create upcall.  If a principal is present in
    the svc_cred, then the hash will be included in the Cld_Create upcall.
    We attempt to use the svc_cred.cr_raw_principal (which is returned by
    gssproxy) first, and then fall back to using the svc_cred.cr_principal
    (which is returned by both gssproxy and rpc.svcgssd).  Upon a subsequent
    restart, the hash will be returned in the Cld_Gracestart downcall and
    stored in the reclaim_str_hashtbl so it can be used when handling
    reclaim opens.
