Bram Matthys fdb256ddcb NOTE: WIN32 DOES NOT COMPILE AT THE MOMENT 2006-05-21 23:32:57 +00:00
Bram Matthys 5757c1a50e +extern MODVAR char modebuf[BUFSIZE], parabuf[BUFSIZE]; 2006-05-21 23:26:12 +00:00
Bram Matthys fe4c8b4a83 - Added 'real' aliases, this are aliases that map to real commands, so you can for example
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.

Bram Matthys e265c08729 - Module coders: For cloaking, added a new callback type CALLBACKTYPE_CLOAK_EX (which replaces
CALLBACKTYPE_CLOAK). This passes 'aClient *sptr, char *host' instead of only 'char *host'
  to the cloaking module, which can be useful if you need to cloak on something other than
  IP/host. Suggested by fez (#0002275).
  Module may still provide only CALLBACKTYPE_CLOAK though, in fact this is what the official
  cloaking module does. So no updating of cloaking modules needed.
  A side-effect of this "extra cloaking" callback is that we needed to change make_virthost()
  which now has an extra parameter in front, and another side-effect is that calling the
  CALLBACKTYPE_CLOAK may not work since only *_EX might be available. To my knowledge there
  are very few modules (only 1 I know) that will have a problem due to this, so sounds like
  an affordable tradeoff.

Bram Matthys dabbe786be - Fixed Microsoft Visual Studio 2005 (8.x) unable to compile, and, after fixing that, causing
a lot of crashes. Both are now fixed. Reported by Zell, Yamake, and others (#2875, #2704).
  Fix provided by Xuefer. This also gets rid of some annoying and useless compile warnings
  as well.

Bram Matthys 8607d950b7 - Made the IRCd calculate the cloaked host only once upon connect, and store (cache) it.
- 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.
2006-04-16 23:27:56 +00:00
Bram Matthys 8ff913a2db - c-ares (currently, a forked off version) enhancements:
- '/quote dns i' now shows the nameserver settings (which is taken from /etc/resolv.conf
    on *NIX, and from the registry on Windows)
  - We no longer depend on a C++ compiler (was useless c-ares dependency caused by libtool)
  - '/REHASH -dns' now rereads the resolver data from resolv.conf/registry, no IRCd restart
    needed anymore. It's currently kinda experimental however, but I *think* it will work ok.
  Unfortunately the above features required some ugly hacks if curl was enabled, so if you
  use curl (Remote includes), feel free to test on your OS (Linux, but especially FreeBSD
  and the other *NIXes) to see if things still compile (make clean; ./Config && make).
2006-04-11 22:00:01 +00:00
Bram Matthys 54c2296dae - CGI:IRC: gzlines, zlines, throttling, and unknown connect floods are now all checked for
clients connecting trough a CGI:IRC gateway that is in cgiirc { }. This might also fix a bug
  where (g)zlines were not applied to CGI:IRC clients, reported by devil (#0002850).
2006-03-14 19:47:08 +00:00
Bram Matthys fd5c1f778f - Fixed bug in currently unused code, reported by DeadNotBuried (#0002835).
- 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 ;).
2006-02-26 01:06:10 +00:00
Bram Matthys 07ccc74036 - Redid whole CGI:IRC support. Configuration is now moved to cgiirc { } blocks.
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).
2006-02-16 15:32:16 +00:00
Bram Matthys 99b6f2ea38 - Added CGI:IRC host spoofing support. This means you can mark specific CGI:IRC gateways as
"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.
2006-02-14 16:58:43 +00:00
Bram Matthys dc19350c70 - Redid glob matching. Escaping is now ripped out for normal bans (as it should be), this
means no longer weird issues with +b *\* etc not banning nicks with \ in it.
  ExtBan ~c/~r get special treatment and will use our match_esc [match with escaping]
  routine, that way you can ban channels such as "#f*ck" via "+b ~c:#f\*ck".
  Fix triggered by bugreport of vonitsanet (#0002782).
2006-01-30 20:14:39 +00:00
Bram Matthys f56080324a - Added new charsys languages: belarussian-w1251 and ukrainian-w1251. Patch provided
by Bock (#0002724).
- Fixed memory leak in new resolver.
2006-01-14 00:01:42 +00:00
Bram Matthys 364bf0f605 - Fixes for an amd64 crash problem, reported by Peter Laur (OpenBSD.se).
- Redid some net synching code to make it more efficient (#2716).
- Fixed spamfilter crash problem: the action 'viruschan' is now no longer incompatible
  with target 'user'. Reported by Monk (#0002570).
2006-01-06 19:53:41 +00:00
Bram Matthys a7e3aa01b7 - Made it so you no longer can change your nick to a banned one in a channel, suggested
by vonitsanet (#0002388), partial patch provided by Nazzy.
  This option can be turned off by setting set::check-target-nick-bans to 'no'.
2005-11-10 23:39:12 +00:00
Bram Matthys 35a8c00214 - When OPEROVERRIDE_VERIFY is enabled, we now allow opers to still join any channels listed
in set::auto-join or set::oper-auto-join, even if they are +s/+p. Suggested by ultrotter
  (#0002644).
2005-10-15 23:26:57 +00:00
Bram Matthys eddb406807 - Removed all old resolver code and switched over to c-ares (+our caching routines).
This should get rid of some annoying untracable (and usually rare) crashbugs in the
  old resolver. Besides that, it makes things look more clean and understandable.
  This should be the fix for the following bugids (all the same issue): #2499, #2551, #2558,
  #2559, #2603, #2642, #2502, #2501, #2618, #2616.
  Feedback and testing is very much welcomed (syzop@unrealircd.com).
2005-10-10 14:32:12 +00:00
Bram Matthys f535167cf9 - Added 'warn' target which is basically the same as 'block' except it does not block ;).
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).
2005-09-25 21:49:19 +00:00
Bram Matthys 4f40d73aa4 - Moved all TKL code and register_user to modules (using efuncs), that means 20 functions
and 2000 lines total that can be hotfixed if needed ;). The effort involved in moving all
  this sucks a lot though :/. This might need some more testing to make sure it doesn't break
  anything.
- Updated support OS list in documentation.
2005-06-05 00:58:36 +00:00
Bram Matthys 2c500fcf72 nickchars...
- Build in some additional checks (especially for Chinese).
  - Fixed a bug in chinese character range (affecting 3.2*)
  - Relaxed nick character checking from remote servers (rely on NICKCHARS= PROTOCTL
    to deal with problems). This is useful to prevent any kills in case we slightly
    change the characters that are allowed in a language.
2005-02-22 16:47:20 +00:00
Bram Matthys 97d4be791b - Added NICKCHARS= in PROTOCTL. This indicates which languages are accepted in nicks.
If 2 servers try to link and the allowed nick characters do not fully match, then
  the link will be rejected. Note that this will not prevent you from 3.2.2<->3.2.3/CVS
  charsets mistakes, but only with linking CVS/3.2.3+ servers. Suggested by Troco (#0002360)
  This might need some additional testing, but initial results are positive :).
2005-02-20 22:05:06 +00:00
Bram Matthys 8650c97cd3 - No longer cutoff nick upon illegal character -- just reject the whole nick. The nick is
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.
  If you wonder why your language is not yet included or why a certain mistake is present,
  then please understand that we are most likely not experienced (at all) in your language.
  If you are a native of your language (or know the language well), and your language
  is not included yet or you have some corrections, then contact syzop@vulnscan.org or
  report it as a bug on http://bugs.unrealircd.org/
2005-02-19 20:47:41 +00:00
Bram Matthys d3a0bb92f6 - Added channelmode +j (jointhrottle), syntax: /mode #chan +j X:Y, and then it will
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).
2005-02-12 00:05:08 +00:00
Bram Matthys 432e3a3a6c - Win32 crash fixes due to modulizing 2005-02-04 20:03:46 +00:00
Bram Matthys 8eb88be500 - Made unreal_copyfile try hardlinking first, if that fails.. it will try to copy
(perhaps this should be a different function?). Anyway, this means less diskspace
  is needed (~1.5mb or more), and it also makes it a bit easier for RBAC (#2300).
- Made a new function DoMD5() which is ssl/non-ssl independent. Also made the cloaking
  module and the auth functions use it. Hopefully I didn't break anything ;). Suggested
  by Bugz (#2298).
2005-02-04 00:26:37 +00:00
Bram Matthys bcfc9b85fb dumdeedum.. modulized fixes (timespan <2d) 2005-02-03 17:11:12 +00:00
Bram Matthys 6508c962f8 - Made m_template.c use CommandAdd() and CMD_FUNC()
- 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).
2005-02-03 00:38:40 +00:00
Bram Matthys a557bc50d7 - Added debug code to trace proto-check bugs in DEBUGMODE [IsToken() etc]
- [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).
2005-01-25 23:31:07 +00:00
codemastr 232b172256 Moved channel mode +G to extcmode to make room for invex 2005-01-23 21:45:49 +00:00
Bram Matthys a76e4d4712 - Module coders: sendto_snomask* now only sends to opers, sendto_snomask_normal* can be used
to send to normal users w/the snomask set.
- Fixed dcc filtering a bit more.
- Made usermode 'g' operonly since it didn't do much, reported by DukePyrolator (#0002024).
2004-12-03 22:00:09 +00:00
Bram Matthys 4284c39307 - OperOverride INVITE notices are now also global (if you have the eyes snomask set) (#2212).
- Module coders: New function: sendto_snomask_global().
- Speedup sendto_snomask/sendto_connectnotice/sendto_fconnectnotice code.
2004-12-03 03:32:32 +00:00
codemastr 191127296a Rewrote some of the previous change to deal with some strange issues 2004-11-26 22:14:30 +00:00
codemastr c52dff2da7 Fixed a bug with /rehash and classes due to the config parser rewrite and Modified the module symbol dependency code to do more accurate searching for the module hat contains the necessary symbol 2004-11-05 20:23:59 +00:00
Bram Matthys fae77f21ec - Module coders: Added HOOKTYPE_REMOTE_JOIN, HOOKTYPE_REMOTE_PART, HOOKTYPE_REMOTE_KICK (all
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.
2004-10-06 20:33:13 +00:00
codemastr 23ee49f602 Exported the isupport functions for use in Windows modules. Added a new snomask, +o to show oper-up notices (oper only) 2004-09-04 17:05:25 +00:00
Bram Matthys 1bd085164b - Fixed possible crash id /rehash'ing and a servername was just resolving (due to
/connect or autoconnect) and was not present in the cache. Reported and traced by sh0
  (#0001976).
- Fixed compile bug at *NIX caused by ModuleGetErrorStr fix.
2004-07-22 21:57:44 +00:00
Bram Matthys 5877a32b3b - Fixed "quickly-rehashing + autoconnect linkblocks = crash"-bug. This involved fixing
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).
2004-06-25 23:50:08 +00:00
codemastr 58943b710c Added CIDR support 2004-06-17 21:16:58 +00:00
Bram Matthys 47f3c43295 - Various (non-critical) fixes for dccallow reported by Rocko (incorrect nick in deny msg,
added set::maxdccallow in docs, added bmp/vob/log/ to dccallow.conf).
2004-06-10 15:53:13 +00:00
Bram Matthys 6ec3822ce1 CmdoverrideAdd, DCCALLOW, allow dcc { }, umode +v change, register_user fix.
- 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).
2004-06-10 02:26:32 +00:00
Bram Matthys bfde79e41d - And another one, should be fixed now. 2004-05-31 18:49:26 +00:00
