commit 256cd80bd60d1194bc5148fb7bd656a0fd8a5a27
Author: Christine Caulfield <ccaulfie redhat com>

    [CMAN] valid port number & don't use it before validation
    cman_send_data didn't validate the port number. This was
    not a great problem, but it was slightly silly.
    cman_start_recv_data used the port number before validation
    in a debug message, this could crash the server if debug
    is enabled and a very large port number was passed in.
