This is the code to implement a bridge between IRCnet 2.10.x servers
and Hybrid/comstud/th servers.  There are two parts, a bridge between
TS servers and non-TS servers, part1-ts-to-non-ts/ (any variant)
and a bridge between 2.8 and 2.10 servers, part2-ircnet/

There are three ways to do the TS to non-TS bridge

part1-ts-to-non-ts-hyb4.3/
channel.c                    - This is needed to reconstruct an SJOIN
                               from an IRCnet combined JOIN/MODE.  Stick
                               this in ircd/ in the source tree.
                               NOTE:  This violates TSora, but it's needed
                                      for Hyb5 and higher servers.
channel-ts.diff              - The diff that generates the channel.c above
ircd-hybrid-4.3.tar.gz       - The base distribution.  This MUST be configured
                               to allow Non-TS server linkages.
no-ip-links.diff             - This patch removes the annoying [ip] in LINKS
                               Apply to s_serv.c

===OR===

part1-ts-to-non-ts-csr31/
csr-channel-ts.diff          - This is needed to reconstruct an SJOIN
                               from an IRCnet combined JOIN/MODE.  Stick
                               this in ircd/ in the source tree.
                               NOTE:  This violates TSora, but it's needed
                                      for Hyb5 and higher servers.
csr-no-ip-links.diff         - This patch removes the annoying [ip] in LINKS
                               Apply to s_serv.c
irc2.8.21+CSr31pl4.tar.gz    - The base distribution.  This MUST be configured
                               to allow Non-TS server linkages.
csr-wallops-allow.diff       - This patch allows user generated WALLOPS to
                               be sent through
csr-ts-second-part.diff      - Another patch that must be used to help stop
                               TS0 propogation

===OR===

part1-ts-to-non-ts-ts3ora/
irc2.8.21+TSora3.tar.gz      - The base distribution.  This MUST be configured
                               to allow Non-TS server linkages.
ts3-channel-ts.diff          - This is needed to reconstruct an SJOIN
                               from an IRCnet combined JOIN/MODE.  Stick
                               this in ircd/ in the source tree.

ts3-no-ip-links.diff         - This patch removes the annoying [ip] in LINKS
                               Apply to s_serv.c
ts3-operwall.diff            - This patch adds an OPERWALL command, which
                               just calls m_wallops.  This will transparently
                               transform OPERWALL's to WALLOPS
ts3-wallops-is-not-channel.diff
                             - Allow WALLOPS to be passed through without
                               turning them into PRIVMSG's to #wallops

--

It is recommended that you use 2.8.21+TS3ora, as the other two have
"bastardized" WALLOPS commands, automatically turning WALLOPS into OPERWALL's
downstream, even with the patches in broken/ installed.

part2-ircnet/
2.9.2p3.ip-hide.diff         - This patch removes the annoying [ip] in LINKS

2.9-operwall.diff            - This patch adds an OPERWALL command, which

2.9-nocomment.diff           - This removes the nick from the PART comment
                               in anything coming from the Hybrid side
irc2.9.2p3.tgz               - The base distribution.  This MUST be configured
                               to allow 2.8 protocol linkages.  It may also
                               be good to disable SERVICES on this part of the
                               bridge.
wallops-allow.diff           - Allow WALLOPS to be passed through without
                               turning them into PRIVMSG's to #wallops

The network can be constructed like the following

 /------------------------\

 |Running Hybrid 5/6/7    |
 |CSr29 or higher         |
 |comstud 1.x             |

Although this is a little complicated, and brings ancient code into the mix,
I believe that it is a good way to bridge the gap between these two protocols,
allowing for most normal server functions to go through without issue.  Some
things will not properly go through the bridge.  Services will not appear
on the other side (services as IRCnet implements), channels MAY have desync
issues, and there's a possibility of weird collides.  IPv6 clients may be
rejected by the Hybrid side, especially if old Hybrid servers are present.

Many things will work though, including all normal channel activity, KILL's
and IRCnet's ident prefixes.

At the present time, user generated WALLOPS will not pass through part1.

As I test more, I will add more to this document.

This bridge is not in production anywhere at the present time.
