Author: ngie Date: Fri Jul 8 20:40:50 2016 New Revision: 302454 URL: https://svnweb.freebsd.org/changeset/base/302454 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.
