New Revision: 301605
URL: https://svnweb.freebsd.org/changeset/base/301605

Log:
  Bounds check rpcbs_rmtcall(..) to ensure rtype is less than RPCBVERS_STAT
  
  Not returning if rtype == RPCBVERS_STAT will cause us to overrun the inf array, as
  it's defined to be exactly RPCBVERS_STAT elements in rpcb_prot.x:
  
  > include/rpc/rpcb_prot.x:typedef rpcb_stat rpcb_stat_byvers[RPCBVERS_STAT];
  
  The proposed change also matches the rest of the rtype upper bound checks in the
  file, so the original change was likely a typo.
