TR-IRCD

IRCD Software

The TR-IRCD 5.0 is no longer based only on Bahamut, though the procotol modules use the same definition. Network code, and module code ideas are borrowed from hybrid-7, the coming EFnet ircd. Information about hybrid can be gained on http://www.the-project.org.

Current Release 5.1.x

a) Restructuring

The ircd now supports modules and dynamic linking of modules.
The whole network architecture has been rewritten. Old Bahamut network code, which was based on an ancient version of hybrid (5.3) is totally removed. The new architecture is mostly inspired by hybrid7.
The ircd can now be compiled to choose between select/poll/kqueue/devpoll/SIGIO
Old linked list structures are removed, new double linked lists are introduced
Many code sections are improved.
File descriptor management is improved, in order to work with the new network code
DBuf* and friends are removed, linebuf and friends from hybrid7 are introduced
Heap Allocation functions are improved
Protocol message management functions are improved.
Introduction of hook management similar to hybrid7
A new ircd.conf, similar to the one from hybrid7 is introduced.
Channelmodes can now be loaded just like protocol command modules to the ircd while running.
The Ircd is now compatible with other state of the art ircds:
TR-IRCD 4.x
Bahamut Pelennor
Bahamut Halcyon
The Ircd supports protocol modules which do the initialization for compatiblity and evolve callbacks for different functions so that the server can send different lines to different ircds (NICK, SERVER, CAPAB, etc...)

b) Management

The ircd no longer uses flags and similar in the main loop, it uses an event manager
The name resolving code has been improved, libadns is now integrated.
The ircvsnprintf() is improved and introduces new determiners:

%C = client structure name, depending if a user structure is available, only the name or nick!user@[fake]host
%~C = client structure name
%^C = client structure name, depending if a user structure is available, nick (user@host)
%*C = faked server name (if servername is being hidden), or equivalent of %D
%!C = client structure ID.
%H = channel structure name
%K = confitem structure name
%N = protocol numeric value

Whole sendto_* function set has been rewritten.
New prefix preparation functions are introduced. Currently to support Tokens, and identities from Bahamut 1.6
Numerics and notices are sent easier.
Newly created channels are +Tn instead of +tn
A new local channel &SNOTICE is introduced, to send even less notices directly to ircops.
Identity management similar to Bahamut 1.6
Zipped links and encrypted links are now fully functional.
The Ircd can be run in compatibility mode, then every kenora extensions will be disabled and the ircd will work like chimera.
This disabling includes identities, tokens, and some channelmode modules.
In native mode the ircd supports the new CLIENT line
The Ircd supports Greek to Greeklish conversion via the usermode +t (translation) (Code evolved from irc.gr ircd)
The Ircd can be compiled with OpenSSL Support to create the DH Key instead of the GMP based way. Both ways can be used.
MD5 based checksum control code a la Bahamut Halcyon has been added, can be done via /hash
The ircd completely supports IPv6, both for client and server connections. The included asynchronous dns client library ensures correct resolving of IPv6 addresses.
A new conversion script takes care of the conversion from the old configuration files to the new format.
Kline behavior is changed, klines will no longer be written to the server kline file, and zlines also not.
A new LogEvent system handles log functions as events and manages them when called.
Makefile has also support for uninstall and uninstall_all
Detection for GNU Make utility is available

c) Technologies

Token Version 1 protocol support is finalized
Many new modes are introduced:
Channelmode +x : Hides the nick, who issued OP only commands: MODE/TOPIC/KICK
Channelmode +M : Moderated nick!user@host's : addresses that cannot send to a channel.
Channelmode +z : Banned channels : Users in given channels cannot join this channel ( +z #ircops )
Channelmode +T : Topic change only by protected users
Channelmode +h : halfops, users that are permitted to kick
Channelmode +f : Flood control (Lines:in time) works perfectly with the new flood code from hybrid7
Channelmodes +N : No users with unresolved IPs may join.
Multiple language support similar to the way services works, therefore also not compatible to the way hybrid7 works. User based language selection will be possible (/setlang), but also server standard language will be allowed to be changed.
The ircd can easily detect http proxies and disconnect connections from them.
Under contribution, /locops, /sadmins, /admins, /rnotice is available.
RNOTICE can be used to send a notice to all registered users.
Server Names can now be hidden, there is a server hide technology that can be configured to hide servers in /links, /map.
Or read LINKS from a file, or flatten the output of links, that every server looks as if connected to the local server
A new command, TMODE, ensures that channel modes are timestamped and modes from the newer channel after the netjoin are ignored.
The NETSET command can be used to use /set for all network servers.

d) Porting

The ircd can now be compiled under this environments: GNU/Linux, FreeBSD, HPUX 11.00, Cygwin Latest, Solaris, OSF
Every ./configure option can be used on GNU/BSD
Cygwin does not support shared modules. Therefore, you are required to ./configure with --disable-shared-modules
Preliminary support for MacOS X, with code evolved from hybrid7 is available.

e) Plans

Removal of umode +i, and make +i standard non removeable (Do we need to send it via NICK for backwards compatibility ?)

Features

a) Cosmetic and IRCop friendly issues

Operators can join +b, +i and +l channels
Operators can see /whois (requires umode +h)
Operators can do /names and /who for every channel
Operators can send to +m and +b channels
Quit messages are now filtered for "irc." and "/server"
Only channel operators can send channel notices
Invite requires chanop status as defined with IRCnets RFCs
Modified Operator notices to include the corresponding O:Line hostname and Uid
Modified Qlined nickname texts to include the evaluating qline and reason
m_operdo function : OPERDO command with 3 parameters
/operdo mode #channel parameters
/operdo kick #channel user reason
/operdo topic #channel :topic
Implemented a way to create autokill and kline exclusions. The result is the EXCLUDE command, which is working just like an autokill, but it only reverses the effect. An exclusion prevents any types of klines from affecting a user. An exclusion may expire like autokills, and may also be removed by REXCLUDE commands.
The exclusion list may be viewed through an /stats E, and any temporary exclusion may be removed by an explicit /rehash excludes.
Added new protocol commands: m_ircops, m_map, m_display
m_display requires the third field of the X:Line to print out the server config file
IRCOPS command displays the list of online ircops
MAP command is an oper only command to display network map
DISPLAY command prints out the server config file

b) Protocol Additions

m_nethtm function : NETHTM command to move every server to /htm if desynched
m_(un)gline function : GLINE and UNGLINE commands, actually placing klines and propagating. (Format : /gline duration user@host :reason)
m_svsjoin function : SVSJOIN command to make a nick join a channel, with TS3
m_(un)jupiter function : JUPITER command to jupiter channel name masks, so that they cannot be joined.
Added Command Aliases: /ns for /nickserv, /cs for /chanserv, /ms for /memoserv, /os for /operserv

c) Mode Problematic

Added Chanmode +e : ban exceptions with regards to irc2

Added Chanmode +I : channel invites with regards to irc2

Removed many usermodes, rewrote sendto_*ops_lev to use server owned channels, instead of sending notices.

+s +k +c +m +e +d +f +y +b are removed

Introduced &STATS, &CONNECTS, &NOTICES, &SPAMBOT, &DEBUG, &FLOOD, &REJECTS, &KILLS, &DCCSEND, where the server sends a notice to that channel, the names correspond to those removed usermodes.

Added QUIET usermode flag, and +q Channelmode. Noone except the server may be set quiet, and only the server itself can set a channel +q, even not the U:Lined. If a channel is set +q, a new user joining cannot see other users in that channel. No text can be send to a +q channel. If a user is set quiet, they do not appear in a /names list, and cannot receive channel text. This is a needed option, for those server owned channels are kept open with the server itself sitting in them, and noone should see the server as a user.

Added ZOMBIE usermode flag, can only be set with SVSMODE +z, a zombie may not send privmsgs.

Created #services channel, which is also +q, and used by services for services log purposes.

Every server owned channel, the #services channel are kept +tnOq, except &NOTICES, which is only +tnq. #services is additionally +ps.

Created usermode +R, which stops non +r nicknames from sending text.

Created channelmode +a, PROTECT, which ONLY protects a user from being kicked.

Created channelmode +u, OWNER, which is kick aquivalent to kick and deop protection

d) More Features

Added Usermode +x : spoofed hostnames based on crypt() Requires CAPAB to DT1, a Protocol Change designed by DarkStar and me.
chatops does not exist anymore.
Rearranged source files for many items.
A better was to filter QUIT messages was implemented
Seperated many functions into different files to get a better readibility
Implemented fixes from Bahamut 1.4.29
Fakehosts are created using md5
Added KILLNOIDENT command to /set, which blocks every user without an ident reply.
Added a way to let operators choose their own fakehost output via /server
Added a way to change the ircop fakehost (via the 5.th field of the oper Iline) without changing STAFF_ADDRESS
Added a way to block http proxies.

e) SERVICE structures

Implemented SERVICE structures with regards to IRCnet. These do differ from that what you may be used to from that network, but still use the same concept. A service is a structure between user and server. It is like a user, for it does not receive a burst. But also like a server, because, via the options in SERVSET command, the service can choose what kinds of protocol commands it is willing to see. A Service can be talked to via the SQUERY command, and the list of services online is got through SERVLIST command.
The SERVSET command also differs from that on IRCnet. I used MODE like letters.
The modes on servset are: PONQKSZLRUjkpmt. These mean: prefixed messages, OPERs, NICKs, QUITs, KILLs, SERVERs, SERVICEs, SQUITs, Remote NICKs, UMODEs, JOINs, KICKs, PARTs, MODEs, TOPICs.
The commands look like these:

SERVICE name ident :description - if a client is connecting to the server.

SERVICE name timestamp hopcount flags ident host server :description - if a remote server is introducing a service

A Flag is got from the S:line, U for Ulined, A for AKILL enabled, H for Routing capable.

S:hostname:password:name:flags:class

SERVSET name +modes-modes

is the way the servset command should be used.

SERVLIST does not have any parametres, and

SQUERY name :text is the usage for the squery command.
