map the command '/BLAH 5' to 'NICK idiot5'. More info in docs on alias block.
- Modulized: badwords system (src/badwords.c is now gone) and StripColors/StripControlCodes
to m_message, multiple netsynch routines to m_server, send_list to m_list, a certain mode
routine to m_svsmode, all /MSG IRC.. webtv stuff to src/modules/webtv.c which is compiled
with m_message.
This means another ~1500 lines of code are now in modules (and thus can be upgraded on
the fly), which brings the total of modulized lines at 32K.
- When checking if a user is banned, we always check the cloakhost too. Previously we could
not do this if the user had a /VHOST (=a minority of the cases, but still...). In short,
this is some extra protection to combat ban evasion.
- Performance of is_banned() *slightly* improved (just 1-2 usec, but 7 usec if no bans).
- [Module coders] For extban routines, we now offer a routine extban_is_banned_helper(buf)
which can be used instead of the ban_realhost/etc static chars stuff, see
extban_modeq_is_banned for a (real-life) example of how this is used.
- [Services coders!] Added PROTOCTL CLK (requires NICKv2) which adds an extra field in the
NICK command (when a user connects) right before the infofield (gecos).
The added field contains the cloaked host, that is: the masked host if +x would have been
set. This field is ALWAYS sent, regardless of whether the user is actually +x or not.
Services can then store this field in memory, to know the host of the user if the user
is set +x (+x-t). This is a (better) alternative to PROTOCTL VHP, with no race conditions,
and avoids some other VHP problems.
VHP will stay supported though... so it's not mandatory to switch over.
- Modulized NAMES command (can now be upgraded on the fly, if ever needed).
- Added NAMESX support, seeing both mIRC (5.17) and XChat support this. What this does is
send all rights of all users on the channel in the NAMES reply (eg: @+Syzop if the user is +ov)
instead of only the highest one (@Syzop in previous example). We only do so if the client
explicitly requested this via a NAMESX in a PROTOCTL message (eg: 'PROTOCTL NAMESX').
Note that there is a glitch: since most clients only send the PROTOCTL NAMESX after they
see NAMESX listed in the 005 announce message this has the effect that if there are
set::auto-join channels present (where users are automatically joined to by the server) the
extended NAMES reply will not be sent for those channels, because from the IRC server' point
of view the join happened before the PROTOCTL and hence it does not know the client wanted
NAMESX at that point (the result is not catastrophic: the old-style NAMES is sent for those
channels). Anyway, for all non-autojoin channels this works great. So still worth adding IMO.
Originally suggested in #0000606.
Side note: this does not mean we dropped the idea of (also) having a challenge-response
system for good ;).
We now support the webirc ('webirc_password' in CGI:IRC) method, which is kinda superior
to the older method ('realhost_as_password').
See the Unreal documentation (section '4.36 - Cgiirc Block') for details on how to configure.
- Changed quoting color in unreal32docs.. looks better now IMO (only English docs updated).
"trusted" and the IRCd will show the users' _real_ host/ip everywhere on IRC, instead of the
_CGI:IRC-gateway_ host/ip.
To do so you must set 'realhost_as_password' to 1 in your cgiirc.conf. And add the
CGI:IRC gateway(s) you fully trust to set::cgiirc::hosts.
set::maxbans in the configfile, note that you probably also want to enlarge set::maxbanlength
as well (see docs) or else you will hit that limit first.
- Changed the default maxbanlength from 1K to 2K, which in practice will mean people can set
a lot more bans since in practice the 60 (maxbans) limit was never met because the
maxbanlimit was set so low.
you have to put 'spamfilter yes;' in every alias block you want to get filtered.
This is so you can have for example /MS filtered (due to heavy spam), while keeping
/NS and /CS unfiltered. Reported by Homer (#0002496).
- The memoserv aliases (/MS and /MEMOSERV) now have spamfiltering enabled by default.
It also sends a numeric to the user saying the command has been processed, but a copy
has been sent to ircops. I feel this is a good idea for privacy reasons (anti-spy),
though I don't know how users will react to this. If you are using this on your network
and get users bothering you about it (or before that ;p), it's probably a good idea
to explain it somewhere on your site or FAQ :).
Example usage:
/spamfilter add p warn - Testing_mirc_decode_filter \$decode\(.*\)
[WARNING] The numeric text is likely to change in the next few weeks (early-cvs-commit).
- If a class block was removed and any other blocks would be referencing the class block
(such as: allow::class, oper::class, link::class), then this would cause a crash.
Reported by Mike_ (#0002646).
- CMDLINE_CONFIG behavior change: command line configuration is now still permitted
if #undef'ed (which is the default) if uid==euid && gid==egid, since it doesn't make
any sense to disable it then and is in fact just plain annoying.
- Added FAKELAG_CONFIGURABLE option in include/config.h, this enables an option called
class::options::nofakelag, which disables "fake lag" for a certain class (that is:
the artificial delay introduced by the ircd to prevent flooding is turned off,
allowing the user to flood at full speed).
IT'S USE IS DISCOURAGED UNLESS YOU REALLY KNOW WHAT YOU ARE DOING.
Sorry, option is not in ./Config -advanced since I don't get autoconf working, but it's
such a scary option that this might as well be a good idea to keep in config.h anyway.
This feature has been suggested for several years (and refused), but the final
suggestion (with implementation specific hints) came from Gilou in bug #0002207.
- changed a comment slightly in m_tkl.c to get rid of harmless warning ;)
- Redid include dependencies in Makefile, this makes things safer because on any .h change it
would force a recompile of all files, but it could mean things will be a bit slower for us
coders unless we tweak it later on.
- Changed whois a bit to print less useless results.
- Added several indicators to the "detect binary incompatible modules"-system such as detecting
of a ziplinks module on non-ziplinks (on windows this is ok however), nospoof module on a
a server without nospoof server, etc. Hopefully this will help some people preventing odd
crashes because they did not recompile or (re)install modules properly.
- Added './unreal backtrace', so far this has only been tested on Linux and FreeBSD.
- Fixed a bug making ./Config not load the previously stored settings on Solaris 10 and
probably other Unixes, reported by lion-o (#0002474).
- If a locop now has can_override/can_gkline/can_gzline we will print out a warning and
convert it to globops. This is also what we always did for can_globalroute/can_gkill
(well, except the warning). Giving such NETWORK (GLOBAL) privileges to a LOCAL operator
does not make any sense and is therefore no longer allowed.
still cutoff if the nick is too long. Basically this is the same way as Hybrid does it
so it should work ok :).
- Added nick character system. This allows you to choose which (additional) characters
to allow in nicks via set::allowed-nickchars. See unreal32docs.html -> section 3.16
for a list of available languages and more info on how to use it.
Current list: dutch, french, german, italian, spanish, euro-west, chinese-trad,
chinese-simp, chinese-ja, chinese.

throttle the number of joins per-user to X in Y seconds. Idea from Angrywolf (who
wrote a module that did this before). This might need some more testing :).
It's enabled by default but can be #undef'ed in include/config.h (line 449).
- Modulized a lot of commands and related subfunctions: NICK (750 lines), USER (200),
MODE (2300), WATCH (250), JOIN (600), PART (250), MOTD (100), OPERMOTD (100),
BOTMOTD (100), LUSERS (100). More will follow soon (probably including more subfunctions
related to existing commands).
- [Module coders] Added new function: do_cmd(cptr, sptr, cmd, parc, parv) which is an
uniform method to call any other commands. For more info, see description in src/parcket.c.
This will be used for any further modulization of commands that need to call other
commands, like NICK (will be done soon).
work just the same as the HOOKTYPE_LOCAL_* variants).
- Module coders: HOOKTYPE_REMOTE_CONNECT is now also called during net-merge. You can use
IsSynched(sptr->srvptr) to find out if it's called due to a net merge (0) or a connect (1).
- Added spamfiler 'user' (u) target. This regex is checked against nick!user@host:realname
when a user connects. This makes it easy to ban drones with simple patterns.
For example: '/spamfilter add u gzline 86400 Drone[0-9]+!.+@.+:Drone[0-9]'
would kill any drones that have both a nick and realname with 'Drone' followed by digits.
that you should pass the ZIP_LINKS etc options to 'nmake -f makefile.win32 custommodule'
many people didn't do this which caused odd problems when reading certain clientstructs.
Module coders: in the meantime, for 3.2.1 mods, use something like:
nmake -f makefile.win32 USE_ZIPLINKS=1 ZLIB_INC_DIR="c:\dev\zlib"
ZLIB_LIB_DIR="c:\dev\zlib\dll32" custommodule MODULEFILE=m_mymodule
For 3.2.2+ these additional parameters will no longer be needed (but wouldn't harm either).
multiple reference count bugs, one related to sptr->serv->conf, and another one related
to sptr->serv->class. Both caused problems when someone did a /rehash when a server
was in the process of connecting (so it might also happen when connfreq was hit and you
did a /rehash). Original bug was reported by sh0 (#0001872).
- Updated example.conf: added all new flags we added in the example block, removed
old confusing comment on SEGV logging, config.h: ripped out lPATH since that define
isn't anywhere used and is only confusing.
because it's slightly faster (already replaced all of them in src/s_kline.c).
GetIP(acptr) will return the ip for local users and remote users that support NICKIP,
it returns NULL for remote users that are on non-NICKIP servers (or have non-NICKIP
servers along their path).
- internal: tkl_add_line now returns aTKline *
- Added some more hooks:
- HOOKTYPE_TKL_ADD [aClient *cptr, aClient *sptr, aTKline *tk]
- HOOKTYPE_TKL_DEL [aClient *cptr, aClient *sptr, aTKline *tk]
NOTE: 'NULL, NULL, tk' is used for *lines that are removed due to expiring
- HOOKTYPE_LOCAL_KILL [aClient *sptr, aClient *target, char *comment]
- Module coders: if CmdoverrideAdd() is called for an override that is already in place, it
now sets MODERR_EXISTS as errorcode and returns NULL (previously it added duplicates).
In the past module coders had many issues with PERM mods... you had to use weird tricks,
but now you can (and should!) just override on INIT and on HOOKTYPE_REHASH_COMPLETE.
- Moved register_user declaration to h.h, updated call in m_pingpong.c (due new 'ip' field).
- Usermode +v ('receive dcc send rejection notices') is oper-only now for privacy reasons.
- Added dcc allow { }, which allows one to make exceptions over deny dcc { }.
- Added deny dcc::soft and allow dcc::soft item, if set to 'yes' it allows someone
to explicitly override it per-person via /DCCALLOW (see next).
- Added DCCALLOW system, taken directly from bahamut.
With this system you can block certain (or all) DCC SENDs and then allow the user to
'override' this limit for every user he/she trusts via '/DCCALLOW +User'.
This is an attempt to stop (or at least limit) the spreading of viruses/etc.
See '/DCCALLOW HELP' for more info.
- Added example dccallow.conf which filters everything except some known
'safe types' (jpg, jpeg, png, gif, etc). Note that the purpose of this file
is NOT to get a complete list, rather to limit it to a few 'known safe' entries.
- Added set::maxdccallow: max number of entries of the DCCALLOW list (default: 10).
- Added release notes (no, we won't release 3.2.1 anytime soon.. just updating ;p).
- Added various extra messages to make it a bit more easier for people who are
upgrading (win32 commands.dll, cloaking mod).
- Made win32 ssl<->non-ssl modules binary compatible.
- Added ssl/non-ssl check in Mod_Version on *NIX.
- Added set::options::flat-map: This makes all servers look like they are linked
directly to the server you are on (/map, /links), thus you cannot see which server
is linked to which ("hopcount"). This can make it a bit harder for kiddies to find
any 'weak spots' (which server to attack/[D]DoS). Obviously opers will always
see the real map.
- It now goes to <prefix> and higher, so '/notice +#chan hi!' goes to +vhoaq
- You need at least voice in order to be able to msg/notice +#chan, %#chan or @#chan
- You need at least ops in order to be able to msg/notice &#chan or ~#chan
- Any multi-prefix targets will be converted automatically (eg: ~&@#chan to @#chan).
- internal: use of the CHANOPPFX macro is now deprecated.
All of this was done to make it a bit more 'safe' and userfriendly (#0001812).
in a netjoin when there was no need to (nothing to synch).
- Added spamfilter::except which allows you to specify targets
(eg: channels) where spamfilter should not take action. Requested by Fury
(#0001586). Ex: set { spamfilter { except "#spamreport,#help"; }; };
- Improved 'viruschan' spamfilter target:
- better msg after the forced join
- +oaq's in set::spamfilter::virus-help-channel receive a notice about
which filter the user matched.
- it disables all commands except PONG, ADMIN, and msg/notices to
set::spamfilter::virus-help-channel.
- Made snomask +S also show the spamfilter reason field.
- Added class::pingfreq checking, should be 30-600 now.. else you might
get mysterious (mass) disconnect issues.
- Lol, I made /connect dissapear during modulizing ;).
- Fixed a few wrong macro's (ircstrdup/ircfree) in s_conf.c causing
very weird behavior... This also fixes a bug where set::spamfilter::ban-reason
would have the value of ban-time.
- Improved spamfilter again.
- The new syntax is:
/spamfilter [what] [type] [action] [tkltime] [reason] [regex]
[tkltime] specifies the duration of any *lines placed by this rule.
[reason] specifies the *line, kill and/or block reason.. no spaces
allowed, but '_' will be escaped to a space.
In both cases you can simply use '-' to skip and use the default.
Ex: /spamfilter add p block - - Come watch me on my webcam
/spamfilter add p gline 3h Please_go_to_www.viruscan.xx/
nicepage/virus=blah Come watch me on my webcam
- A message is now shown if the msg/notice/dcc is blocked.
- There are 2 new spamfilter action types:
'dccblock' will mark the user so (s)he's unable to send any files by DCC.
'viruschan' will part the user from all channels and join
set::spamfilter::virus-help-channel (default: #help).
this action might be improved to do more later.
- Internal: added EXTTKL PROTOCTL, this determinates if 10 parameters
instead of 8 are supported for m_tkl (used by spamfilter add).
This new system needs some testing... :)
spamfilter::word to spamfilter::regex to make it even more clear (since we match
on the whole line and have nothing to do with words.. 'word' doesn't make sense).
- Updated docs with some better regex examples, reported by AngryWolf (#0001520).
