#3 IPv6
Here's a not-so-broken(tm) IPv6 patch for .11 (yes, I
know this should be in .12 or .13, but it's easier to
test this way).
What works:
* connecting clients/servers via v4 or v6
* dns for both
* uping
What doesn't work:
* ipcheck's hashing
* ip-based glines
* ip-based /who
* allowed-ip-mask in P:lines
* /userip is truncated
* base64 IPs in NICK messages are truncated
* probably more
Tested on a Linux 2.4.17.

Now works under FreeBSD (tested under 4.7), base64 IPs are
ok, ipcheck improvements, /userip works.
As it is now, if there are no ipv6 connections, nothing in
the behaviour should change.
IPv6-unaware servers on the same net will see only the last
32 bits for /userip on a v6 client.

Fixed glines, /who and IP bans, all with CIDR capability
The bans don't overlap correctly though.

You just love making the forward port of .11 to .12 very hard
to do. :P
nahh, patch looks good! ;)
Keep up the good work, vampy. :)

It looks nice...but I'm afraid I have to nit-pick. Remember
that not all platforms have the IPv6 address structures like
in6_addr or sockaddr_in6. This unfortunately makes things
more complicated, because even those ircu's on such
platforms must be able to handle IPv6 addresses they receive
over the network. I'm also curious about how IPv6 addresses
are propagated across the network when the user's host
doesn't reverse-resolve--theoretically, the IPv6 address
could begin with a ':'.
I would like to apply this patch to .11--I don't think
forward-porting's going to be much of a problem since I'm
hoping to have libevent to use in .12, and supporting IPv6
addresses on non-IPv6-enabled platforms is one of the design
goals for that project. Although libevent isn't anywhere
near done, I think the abstraction code I have in there may
give you some ideas of how to work around the
IPv6-on-IPv4-only machines problems I pointed out above.
Could you address my concerns and provide an updated patch?
You have time--I don't expect to apply it until u2.10.11.04
or later, because it's so big and needs testing :)
Thanks for the good work!

This is an ultimate specialiy for all people please allow ipv6 it
is the best thing I have ever seen all people will like it make it
runing as possible as you can that will be an excellent
decision in the history of undernet ipv6 must be available
please make it on the next ircu !!!

If this is not already in .12, let's try to get it there.
Its big enough to make me nervous about putting it in .12...

.12 contains a cleaner and more portable rework of this
patch. (Notably, it does not assume the existence of struct
sockaddr_in6 on the host platform. An IPv4-only server can
link -- and has linked -- into a network with IPv6 servers,
with things like /userip working properly on both.)
