2f0cc2fd05 Don't touch ai_canonname without checking NULL. Current
implementation of getaddrinfo() may return NULL ai_canonname.
There is no consensus how getaddrinfo() should fill ai_canonname
when numeric hostname is given.

b208ff84c1 Add IPv6 scoped address support.
It enables us to control link-local connections by interface like
this:

    ALL : [fe80::%ed0]/10 : allow
    ALL : [fe80::]/10 : deny

c268f6e47c Stop the tcp_wrappers ident code sending a request which is split
across several packets. This is done by not turning off buffering
on the stdio stream for the ident connection. Originally this was
done to avoid reading back what you'd just written into the buffer.
However ANSI C gives a list of functions which should allow you to
safely change direction on a stdio stream, and Wietse found that
fseek seemed to be the most portable.

The original patch used a different workaround, but this should be
a real fix.

8053080cbc Missing tcp_wrapper IPv6 support seemed to be a bug, so commit it.
Now when tcp_wrapper is enabled by inetd -wW,
  several accesses which should be permitted are refused only for IPv6,
  if hostname is used to decide the host to be allowed.
  IPv6 users will be just upset.

  About security related concern.
    -All extensions are wrapped by #ifdef INET6, so people can completely
     disable the extension by recompile libwrap without INET6 option.
    -Access via IPv6 is not enabled by default.
     People need to enable IPv6 access by changing /etc/inetd.conf at first,
     by adding tcp6 and/or tcp46 entries.
    -The base of patches are from KAME package and are actually daily used
     for more than a year in several Japanese IPv6 environments.
    -Patches are reviewed by markm.

99abb2876d Add the ``blacklist'' feature, which allows a path to a filename to
be used as a valid pattern in the access control language.
