At one point it checks for a numeric address and if it sees one, it sets a hint parameter to force getaddrinfo to interpret the host as a numeric address. However that hint is not cleared for subsequent iterations of the loop and if any hosts seen after this point are host names, getaddrinfo will fail on the name. The result of this bug is that you cannot pass a host name to the -h flag. Unfortunately, the first iteration will either process ::1 or 127.0.0.1, so the flag is set on the first iteration and all host names will fail to be processed. The same bug applies to rpc.lockd and rpc.statd, so fix them too. Differential Revision: https://reviews.freebsd.org/D1507 Reported by: Dylan Martin MFC after: 1 week Sponsored by: Sandvine Inc.
