* switch IPv6 advanced API from RFC2292 to RFC3542 (2292 is superseded by 3542).itojun2006-12-097-5/+971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.

* In _gethtent() ignore host.h_length if it is set to 0. Previouslymillert2005-07-241-10/+7
| | | | | | we only ignored it if host.h_addrtype was AF_UNSPEC. Set host.h_length to 0 in _gethtbyname2() since that function does not take a length argument. Problem found by jaredy@
* *hostent() fixes:jaredy2005-07-231-22/+13
| | | | | | | | | | | | - Make _gethtent() static - _gethtbyname() is dead code (succeeded by _gethtbyname2), kill it - _gethtent() requires setting the address family field of the file-scope variable `host' to that of the desired type of the entry being searched for. Change the behavior to enforce this if it is not AF_UNSPEC, which will now allow stepping through entries, and set it to specific values everywhere else. help & ok millert
