beware ircd

changes in server

1.6.3 (2014-08-11)

fixed: a bug affecting G-lines.
made code work on delphi xe5

fixed an lcore bug that could cause a connection to close if a lot is sent to it in one go
work around an lcore problem which would cause the ircd to crash sometimes after a few weeks
increased how much an unreg connection can send, to allow atheme to work (atheme sends its burst without synchronizing, which is wrong)
zero pad the date notation of the motd

1.6.2.2 (2013-07-04)

fixed: resolving user's hostnames did not work if running the ircd as a NT service, and if not using a custom nameserver. only the windows version is affected.

1.6.2.1 (2013-07-01)

fixed that mkpasswd doesn't work on 64 bits windows. it was formerly a 16 bits DOS program, and now it is a win32 console app. no changes to the ircd itself.

fixed lcore bug that prevents working on linux without ipv6 enabled in the kernel
on a netburst if the key changes, propagate a change to clients (new mode shows as *)
"-foreground" commandline param to not fork
removed iso-8859-1 forced lowercase on channel names behavior, it breaks things (utf-8) and others don't do this.
changed all uses of "string" where necessary to "bytestring" (defined in lcore), and likewise for "char", for new delphi compatibility
when length limiting/interpreting (ban) masks, do it in the same way as ircu
silence should exclude services

1.6.1.1 (2011-10-02)

for ircu compatibility, when receiving a BURST message, a lower limit and a lower key (alphabetically) must win

1.6.1 (2011-10-02)

fixed: a bug that would let a user crash the ircd.
fixed: must send +6 server flag in initiating server connection.

fixed: properly rejecting too long DNS hostnames
fixed: /restart does not work on linux
fixed: /svsnick nick NICK - NICK Nickname is already in use

implemented SH sethost hacking (as on quakenet)
fixed: GLINE burst had parameters in the wrong order
various /gline fixes/improvements
fixed: undesired ping timeout if the server is temporarily locked up

1.6 (2009-08-31)

compiled with lcore, an in-house developed cross platform socket/event library, instead of TWsocket, which, in windows, adds support for IPv6, and should improve performance and stability. The Linux version has been using earlier versions of lcore already, but it should have minor benefits from further lcore development.
changed how IPv6 IPs of clients are represented in server-server communication, to be compatible with ircu (2.10.12)

1.5.7 (2004-07-13)

fixed a dns bug which could cause a user to fail to resolve

fixed: the whois "actual userhost, actual IP" reply is 338, not 388.
restart/die: show sender in server notice
I:lines allow "limit/prefixlen" to limit clones from a netblock (needed for ipv6)

fixed: in linux version, DNS looksups no longer worked at all.
one can initially set a deactivated G-line
fix for services which send G-lines in *!user@host format (quakenet O)
propagate force (!) in G-line messages properly

added "reliable clock" option and some related code, and fixed SETTIME.
fixed problem with long notify list: if there are too many parameters, the parser will put the rest, including spaces, in the last parameter, like unix ircd does.
added "hub" option.
server notices for failed incoming server connections (numeric collision, server already exists, hub)
file date/time of ircd.motd is displayed

1.1.5

IRCops can now set G-lines (global only) without services. requires enabling "opergline" setting.
clients can't set a nick containing a ~ character
options code in bconfig.pas rewritten to be based on a table. neater code, and smaller exe file.
fixed: wrong parameter in end of /links reply
fixed: a local user with mode +d set could still see channel chat
fixed: didn't send "inviting" reply.
fixed: silence code is rewritten to be compatible with ircu server-server protocol. it wasn't compatible, causing problems, such as X stops responding.

1.1.4

added invite list (do /invite to see for which channels you have an invite key)
fixed bug in passing on burst messages, which caused serious desynch problems when a bircd server is hub
Added anti net break ride code: net riders are kicked from +i and +k channels

1.1.3

changed ident code to be more stable, it could easily cause an access violation if many clients connect in a short time.
fixed a problem in the install NT service code
removed IP address from unauthorized connection notice, hiding hub IP addresses should be complete now

1.1.2

implemented N:line support; using an N:line allows for different passwords and/or different address (including wildcards) for accepting and connecting
channel ban code didn't have vhost support yet, one could easily evade bans, fixed
silence supports vhost, and cprivmsg/cnotice also checks silence.
pass+server for initiating connection is now sent after completion of the dns+ident lookup. this might fix some problems
fixed problem of reason for a failed connection (ERROR message) not showing
implemented "list stop"
if an opped+voiced user is de-opped, +v is sent to keep clients synched
user's account name is sent/parsed on netburst (+r)
"actual user@host, actual IP" reply in whois, userhost shows virtual host to ircops, not real host.
svsnick is now more compatible with ircu's svsnick patch (on collision, the existing user is always killed)
hack notice for opmode and clearmode
different, probably more secure, random function used for nospoof ping
source: command numbers are less static, it is now possible to easily reorganize the command table and remove commands, etc.
source: more things and commands can now be disabled using conditional defines

1.1.1

fixed a few small bugs in virtual host code and uploaded again
added support for virtual/crypted hostnames, user mode +x
"This server was created" date in source code is now automatically generated by running a program, rather than manual editing
in /whois code, if head in sand, remote whois only with existing nick, better protection against tricky remote whois.
head in sand: more servernames hidden in mode, kick, kill, nick collision
error reply "cannot join channel (+r)" was left disabled. fixed.
fixed: G-line with long duration caused expiration date to wrap to negative value.
fixed bug in parser which caused an accessviolation if an unknown command which matches some criteria is received from a server
join behavior with badchan changed: ircops can join anyway, and can't join if channel does exist.
fixed /join #a,0,#b behavior (user in this case does join #b) and join parser for server-server also parses /join 0
clearmode command can now be disabled for ircops in options
in source code, vhost, head in sand, badchan, can be completely left out using conditional defines

24-08-2002 1.1.0 source release under GPL

1.1.0

added OPMODE, CLEARMODE, ACCOUNT commands, and channel mode +r
protocol change for ircu compatibility: remote connect uses server numeric, not name.
fixed bug: /mode #channel +lk returned "mode char is unknown to me" error
removed G-line reason check (G-lines were not being added for unknown reason)
removed hopcount check for N messages

1.0.27

very small update. a colon was missing in some reply notices.

1.0.26

Found and fixed a leak when connection fails
Servers could not kick. fixed.

1.0.25

Servers can now talk on all channels, unrestricted.
Servers were able to change modes of a modeless channel.
mode #channel +s send by a server always showed like "-p+s" even if +p wasn't set.
a linked gnuworld could cause problems because of NULL character at the end of messages; it's now truncated; fixed.
B message with empty last parameter caused EAccessViolation, fixed.
a space too many in sent B messages, fixed.
bans added by a server during burst, if head in sand is enabled, now appear to be set by local server.

1.0.24

version .23 couldnt link to ircu nets anymore because of added timestamps check; ircu can send 0 timestamps during netburst. fixed.
fixed another small timestamp bug, uploaded again.

1.0.23

"ISON :nick nick" now parsed correctly, also USERHOST and USERIP.
user mode changes which are sent now have a colon prefix for last parameter, gnuworld might need it.
i check the hostname from reverse DNS lookup for being valid, to prevent malformed/dangerous hostnames.
valid servername check did not work, fixed.
implemented optional TopicBurst code, it wasn't there yet, but the option was.

1.0.22

changed code to not use forms unit, 120 kb smaller exe file, less overhead.
fixed quit reasons code (adding Quit: prefix, etc), it didnt work correctly.
improved adding bans code: can't add a ban if it's overlapped by an existing ban, and now *!*@ becomes *!*@*
G-lines are cleared when server restarts
whowas code was left disabled for debugging.
fixed all warnings/hints in source code

1.0.21

MD5+salt oper password encryption, included mkpasswd.exe to create crypted passwords. plaintext and crypted passwords can be mixed in ircd.conf; the length of the password tells if it's crypted
numeric in a SERVER message is now being checked for being valid, preventing problems with short numeric servers etc.
also check timestamps in remote server message

1.0.20

OOPS "/msg server.name x" causes server to crash, client exploitable bug. fixed
added DNS lookup using DNSquery. This can solve possible problems/leaks in winsock internal DNS lookup. to enable, set "dnsserver=" to the DNS server(s) of your choice.
i changed some string properties of user and channel to static (short) strings. may be faster, but 20 kb bigger EXE file :(
i reorganised some code related to penalty, flood, etc. Added "floodbufsize" option
implenented "restrictcreate" option, when set, non-ircops cannot create channels.
added timestamp and proper nick collision code to SVSNICK

1.0.19

removed the "a" from the version number.
change of destroying sockets code
+k and +l mode changes on a netburst weren't sent to local clients
fixes in netburst related code.
bircd.ini is not written during server restart, so user made changes are applied rather than overwritten.
removed some unused code from WSocket unit, 11 kb smaller exe file and probably faster
Added a few more sanity checks
findnumeric caused crash if given bad characters
HACK server notice when receiving a mode from a server link, if origin isn't a chanop.
unless i fix more bugs, this will be the last 1.0.

1.0.a17

on receiving a netburst, mode +k and +l changes were not sent to clients, fixed.
some fixes on modeless channels; TS should always be 0, internally modes +nt are set (no external messages)
Identd lookup when initiating a connection could cause a crash because it tried to use the "port" value from the listener. fixed.
remote port in ident request was incorrect, needed low/high byte swap. fixed.
Fixed problem with SQUIT

1.0.a16

a nickchange by a user on a remote server, same nick, different caps, caused a collision and a crash. i fixed both issues.
a remote join or create without timestamp or a too old (0) timestamp would set the channel's TS to this. fixed.

1.0.a15

receive-code during netburst wasn't stable yet on winNT/2000, commands skipped/duplicated. fixed, tested, verified. a little slower but flawless.
adding new G-line didnt kill users who's IP matched (only hostname) and fast premaskmatch code used here too
the bircd.ini which is written now contains explanation for every option, so you know what you're editing.
fixed a few things related to reading from an already destroyed user (didnt cause a crash but it's not neat)
i now put in code to completely disable a command, a disabled command also does not show in /quote help reply. added "servcmds=" option in bircd.ini to disable /chanserv etc commands.

1.0.a14

oper attempt with bad password caused read of undefined address (caused client connection to hang) fixed.

1.0.a13

+s channels were showing in /list. fixed.
changed and speeded up /whois code
/who mask x didn't show anything
idle time wasn't reset when someone says something

1.0.a12

ircu does not accept SQ with a wildcard server name mask, causing desynch (server exists on one side of the net, not the other) fixed now: full servername sent to servers.

1.0.a11

small bugfix, if connection got "server full", "connections from one ip" data wasn't correctly updated.
fixed all warnings/hints in the source
/who marking code redone, it no longer loops thru all users; faster now
checking for valid userid, and truncating to max length
too many connections from same IP server notice to ircops

1.0.a10

connection limit on Y-lines now works
/stats P and /stats Y show the number of connections on this port/class
fixed a problem with recursed calls to parsing, commands parsed in the wrong sequence, causing for example commands to be ignored, decynchs, etc. happens when receiving a burst, on a fast machine.

1.0.a9

recently introduced bug with server crashes fixed.
the stop signal did not stop the server properly, fixed now
ports can be server only or client only, and hidden (flags S H C in P:lines, see example.conf)
ports can be configured to accept only connections from a given IP block (not mask) use 1.2.3.4\bits notation or lowest-highest notation.
added /stats P
Service name and signal port can be customised (read manual page), allows multiple irc servers on a single machine
minor changes

1.0.a8

changed /WHO code, uses about 10 times less cpu. as ircop, use /who 0 x to see invisible users
some bugfixes/speedups in userid, host, upper/lowercase, etc code
ignoring reverse dns without dots, IP address used instead

fixed: user's TS was not updated after nickchange
added remote version reply

1.1.18

re-enabled deop bouncing for invisible chanserv mode. added minimal support for halfop: it won't desync op/voice. added umode=2 setting: invisible chanserv, modes come from services server.

1.1.17

fixed receive code, it caused errors in the stream if receiving a netburst of some size, causing the services to disconnect on parse errors

1.1.16

added hiddenhost setting (enabled by default) so real hosts are not shown to users in nickserv info/list commands
nickserv accounts with "private" setting enabled no longer match in nickserv list command, except if services operator
