getaddrinfo() accidentally returns IPv4 mapped IPv6 address instead
of native IPv4 address.
Now, getaddinfo() is scoped address ready.  You can put scoped
address within /etc/hosts.

Change IPv6 scoped addr format again based on recent standard discussion.

2000-02-19T16:10:16+00:00

Sorry for the flapping, but no change will be done for 4.0 anymore.
Official standard will be published around April or later.
If different format would be adopted at that time, then support for
the new format will be added to the succeeding FreeBSD 4.x.

Let getaddrinfo() and related functions supports traditional IPv4 format

2000-02-10T02:59:50+00:00

 (shortend format, etc)

   Current KAME getaddrinfo() supports only d.d.d.d format IPv4
   addr. But traditionally inet_aton() and etc support other formats.
   (shortend format and octal/deciaml/hex format)
   Aboud this,
    -As far as the discussion on freebsd-current, many people
     think traditional format should also be supported by getaddrinfo().
    -X/Open spec requires getaddrinfo() also support those
     traditional IPv4 format.
    -RFC2553 say nothing about it.
    -As the result of confirmation in ietf/ipng list, there is
     no clear concensus yet, and the reply was, "RFC2553 update
     and X/Open spec will be in sync"

   So takeing these conditions into account, I think
   getaddrinfo() should also support traditional IPv4 format.

IPv6 scoped addr format is changed as recent KAME change.

2000-02-09T00:38:06+00:00

   KAME scoped addr format is changed recently.
     before:   addr@scope
     now:      scope%addr

   Because the end of IPv6 numeric addr is tend to be truncated in
   `netstat -rn ` output, so placing scope part at starting of addr
   will be convenient.

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

2000-01-27T23:07:25+00:00

just use _foo() <-- foo().  In the case of a libpthread that doesn't do
call conversion (such as linuxthreads and our upcoming libpthread), this
is adequate.  In the case of libc_r, we still need three names, which are
now _thread_sys_foo() <-- _foo() <-- foo().

Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(),
nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo().

Remove all internal libc usage of: creat(), pause(), sleep(), system(),
tcdrain(), wait(), and waitpid().

Make thread cancellation fully POSIX-compliant.

Fix getaddrinfo() behaviour to be more compliant with RFC2553. Patches are

2000-01-26T08:37:29+00:00

obtained from itojun.
  -don't filter address families which are not supported by system at
   FQDN resolving.
  -don't do reverse lookup

I think I checked all lib and tools which use getaddrinfo() if
this change affect them.
