itojun 0c63dd3cf2 correct %d/%u mixup. 2002-06-27 10:22:07 +00:00
itojun 9cdbc86d39 correct bad practice in the code - it uses two changing variables
to manage buffer (buf and buflen).  we eliminate buflen and use
fixed point (ep) as the ending pointer.

this fix is NOT critical.

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.

itojun 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.

itohy 7daefc5a5a Passing "char" values to ctype(3) functions is problematic.
If an argument of a ctype function is outside "unsigned char"
and if it is not EOF, the behavior is undefined.

The isascii(3) is the sole exception of above and it was used to
be used to check a value was valid for other ctype functions in
ancient systems.  On modern systems, the ctype functions take
all values of "unsigned char", and this check is obsolete and
even wrong for non-ASCII systems.  However, we leave the isascii()
untouched for now, so as not to change the current behavior.

itojun d5aee78db5 visit all requests even if we get errors from name server.
this will solve name query failures for IPv4-only node, when
the DNS server returns SERVFAIL or NXDOMAIN (should success with an == 0).

itojun 40e69da142 to honor the search order defined by nsswitch.conf,
getaddrinfo(3) now calls lower-layer resolver functions directly.

XXX code duplicate with gethnamaddr.c/res_search.c - future code
maintenance issue?  Since BIND[89] does not address this issue either at
this moment, switching to BIND[89] does not help.

itojun 823d2a5d81 to synchronize with progress of discussion for post
draft-ietf-ipngwg-scopedaddr-format-00.txt (will be 01),
use "address%interface" notation for extended scoped IPv6 address.

NOTE: the change affects link-local addresses only.  I hope it to be
the final change on it.....

itojun 8829e73e38 preparation to flip extended scoped address syntax.
the specification is still under debate; there is high possibility that
"fe80::1%de0" will be the finalist but i'm not sure yet.

itojun 34a6354b59 revise extended scoped address format support. delimiter and the order
is changed, based on discussion in ipngwg scoped address cabal.
past code:	fe80::1@de0
now:		de0%fe80::1
this will be in sync with next extended address format proposal
(which should be final - I don't want to make this kind of change again).

itojun 59b810d3a5 backout previous commit - freeaddrinfo(NULL) issue. 2000-01-28 08:09:48 +00:00
itojun e4dc489b2c allow freeaddrinfo(NULL). nothing is talked in RFC2553 (maybe in X/Open?).
however, since NRL freeaddrinfo permits it, we need to.

itojun 2705db0080 do not filter address families that are not supported by kernel.
the behavior was introduced in 1.8 -> 1.9, by itojun, and it was
not a correct behavior.

even if we may be able to connect to the the returned addresses,
filtering them out is not a correct thing to do.  for example, even if
you have partial unreachablility in IPv4, gethostbyname(3) will return
IPv4 addresses in the unreachable network nonetheless.

itojun 58481c1c06 fix getaddrinfo(3) and getnameinfo(3).
getaddrinfo(3): result from gethostby* will be broken if we call it again.
deep-copy them.  we have sa_len so configure them.
getnameinfo(3): we have sa_len so configure them.

itojun 1501f61891 bring in latest KAME get{addr,name}info(3).
getnameinfo(3) globs ai_socktype and ai_protocol correctly.
KAME scopeid extension is implemented.

bump up shlib minor
(may not be necessary, but rather big difference in behavior - especially
ai_flags)
