Log:
MFstable/10 r302453:
MFC r301605:
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.
