* compare and shift buffer against a fixed length not strlen derived values.pyr2009-06-051-6/+6

* Add a resolv.conf option to specify the order in which getaddrinfopyr2009-06-042-8/+63
| | | | | | | | | | | PF_UNSPEC queries are made. While there change the default from inet6 first then inet4 to inet4 first then inet6, this prevents the many people with IPv4 only connectivity from constantly trying to contact IPv6 addresses, and also unbreaks many ports who don't use getaddrinfo right. ok deraadt@, plenty of cheering in the room wrt the idea, not loud enough complaining from the v6 crowd.

* Add resolv.conf(5) option to force lookups by TCP: "options tcp"djm2008-08-151-18/+20
| | | | | | | | | | | | | | Also Extend "nameserver" declaration syntax to support port numbers. To avoid ambiguity these are only parsed when the address is enclosed in square brackets, e.g. "nameserver [127.0.0.1]:5353" Together these changes make forwarding DNS over a SSH tunnel very easy, but unfortunately some programs in ports/ implement their own resolvers (e.g. firefox). These will need to be modified to support these options separately. fixes jsing@ reyk@ ok deraadt@ millert@ krw@ + "I like it" from lots
* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-9/+2
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

* switch IPv6 advanced API from RFC2292 to RFC3542 (2292 is superseded by 3542).itojun2006-12-097-5/+971
| | | | | | | | | | the kernel still handles RFC2292 set/getsockopts, so that compiled binary has no trouble running. userland sees RFC3542 symbols only on header file so new code has to use RFC3542 API. bump libc shlib minor for function additions. tested on i386/amd64 by jmc, i386 by brad. checked by deraadt.
