IMHO glibc is right: http://www.opengroup.org/onlinepubs/007904975/functions/getaddrinfo.html - A numeric host address string is not a ``name'', and thus does not have a ``canonical name'' form - if the canonical name is not available, then ai_canonname shall refer to the nodename argument or a string with the same contents. So it would be wrong to do a reverse-dns lookup for _any_ numerical input string? And hence _this_ would be a bug.... $ ./asd 192.168.0.1 getaddrinfo() succeeded, result dwmw2.baythorne.internal ? You are right, for numeric addresses as name parameter ai_canonname must always be a copy of the input string. I've changed that in the current CVS code. Will be in 2.3.3-59 or so. |
