a24f74d0fd Turn the flags argument to getnameinfo(3) back into an int (from unsigned 
int); this is consistent with RFC2553, the current draft-ietf-ipngwg-
rfc2553bis-05 and the majority of deployed implementations.

Also, there is an effort under way to have this changed back to int in
XBD6/XSH6, XNS, and POSIX-2001 TC1.

dddf6754e0 ai_addrlen: size_t -> socklen_t. 2002-05-14 13:50:21 +00:00
kleink
06d36d9eee struct addrinfo.ai_addrlen used to be a size_t, per RFC 2553. 
In XNS5.2, and subsequently in POSIX-2001 and draft-ietf-ipngwg-rfc2553bis-02
it was changed to a socklen_t.

To accomodate for this while preserving binary compatibility with the
old interface, prepend or append 32 bits of padding, depending on
the (LP64 data model) architecture's endianness.

This should be deleted the next time the libc major number is
incremented.

infrastructure and using that infrastructure in programs.

	  of the infratsructure (libraries, support programs, etc.)

	* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
	  building of support for using the corresponding API
	  in various libraries/programs that can use it.

247856f4d7 Fixes from Bill Fenner <fenner@research.att.com> for problems he found 
in FreeBSD's port of this nsswitch code:

- Don't ignore unknown characters.  The old lexer would treat
	hosts:!!!!!!!!@@@@@$%^&*()()*$(files{}{}|||++!)(dns
  exactly the same as
	hosts: files dns

- Recover from errors by looking for the end of a line.  This means
  that having a syntax error near the top of the file doesn't prevent
  a service at the bottom of the file with no syntax error from being
  looked up.

Thanks Bill!

babc498cc8 implement EDNS0 support, as EDNS0 support will be made mandatory for 
IPv6 transport-ready resolvers/DNS servers.  need careful configuration
when enable it. (default config is not affected).
see manpage for details.

XXX visible symbol __res_opt() is added, however, it is not supposed to be
called from outside, libc minor is not bumped.

698d9a8d8b on gethostby* with NIS backend, make a lookup against ipnodes.{byname,byaddr} 
for non-IPv4 address.  obeys solaris8 practice.

XXX does not support scoped address extension, as gethostby* are not
scope-aware.  always use getaddrinfo/getnameinfo.
XXX it is not very useful at this moment, if you define multiple entries for
single hostname.  see PR 10713 for detail.

c8c092ff17 do not try to transmit UDP DNS query forever, in EINTR-busy situation. 
the change uses extra variables which can be avoided,
it is to make the change look similar to BIND8 change.
question: timeout resolution is 1 second (time_t).  should we use
timevals instead?
