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.

Bram Matthys 4530ee5219 - Made it so if the channel is +m but -t, you need at least voice (+v) to change the topic.
Reported by aquanight (#0002233).

Bram Matthys e0b116a663 - Hide stats request if requested by an U-lined client. Suggested by vonitsanet (#0002865). 2006-04-09 19:34:36 +00:00
Bram Matthys eee6d3c8d1 - Local opers may now use /TRACE (local only), suggested by GSF19 (#0002365). 2006-04-09 18:37:38 +00:00
Bram Matthys 6b982f7aae - Fixed (unimportant) DNS resolver problem if using some LAN domains with digits at end,
reported by Bock (#0002843).
2006-04-02 20:13:23 +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 898ff7855d - Partially redid m_message, moved some stuff to a subroutine, etc to avoid duplicate code
- Rephrased/editted part of example.conf and unreal32docs to make it a littttttle bit easier
  for beginners / try to mention the FAQ a bit more explicitly.
2006-03-12 20:56:09 +00:00
Bram Matthys 996381ec47 - Fixed possible netsplit problem (#0002790). 2006-03-05 23:35:48 +00:00
Bram Matthys 3109c877aa - Actually committed src/modules/m_names.c... This tends to help with the compiling process. 2006-02-26 13:29:21 +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 ;).

Bram Matthys 13f99d6bc1 inet.h! 2006-02-16 16:24:50 +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 22921c1b1f - Fixed win32 compile problem due to CGI:IRC support (?) 2006-02-15 11:26:47 +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.

Bram Matthys d223da8a26 - Fixed amd64 problem regarding /*LINE always saying 'The time you specified is out of range',
reported and test shell provided by Tauop.
2006-02-04 20:30:02 +00:00
Bram Matthys 93cb84f67c - Fixed SVS2SNO not always notifying the user of the snomask change, reported by decoder
(#0002767).
2006-01-24 13:29:13 +00:00
Bram Matthys c9648673fd - Made it so banned users cannot change the topic, suggested by aquanight and Stealth (#2233). 2006-01-16 21:11:48 +00:00
Bram Matthys be917865c3 - If you now use /(G)ZLINE usermask@something instead of /(G)ZLINE *@something you get
an error, since specifying usermask should not be done and is useless, since a (G)ZLINE
  takes place BEFORE ident lookups.
- Did the same for /(G)ZLINE *@hostmask (should be *@ipmask), this already was a warning
  in 3.2.3, and is an error now in 3.2.4.
2006-01-16 20:32:38 +00:00
Bram Matthys 1c7c7573be - Fixed some more memleaks, thanks to valgrind. 2006-01-15 14:42:16 +00:00
Bram Matthys 4d47acdbfd - Made the charsys mismatch during linking a warning instead of an error (temp. fix,
until a good solution is implemented without false positives).
2006-01-14 00:16:40 +00:00
Bram Matthys acad82bd3d - Fixed invalid servername in quarantine kill, reported by pinstrate (#0002743). 2006-01-07 12:41:50 +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 054160a74a - Made the link::options::quarantine actually do something... People that get global
oper privileges on quarantined servers will be instantly killed. Bit ugly perhaps, but
  then it actually does what it should (prevent opers on quarantine from getting GLOBAL
  oper privileges). This "fixes" #2510, #2163 and #1968.
2006-01-02 19:44:33 +00:00
Bram Matthys 704918754c - Reverting "Changed the way we build most of the .so's" feature, this caused m_*.so
to be build incorrectly. So now back at normal compile speed :p.
2005-12-08 23:42:35 +00:00
Bram Matthys 91ada621e6 - Added proper "not enough parameters" message for /SETNAME and cleaned up some whitespace
in the function, reported by Robby22 (#0002696).
- Fixed set::static-part set to 'no' not working properly. Reported by Robby22 (#0002698).
- Fixed crash in new resolver, reported by firstof9.
2005-11-16 23:58:02 +00:00
Bram Matthys 675ef5b54d - Made it so coadmins can use /ADCHAT (makes sense, since they already *received*
adchats). Reported by RandomNumber (#0002557).
2005-11-13 00:19:28 +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 184dedf72a - Couple of source code cleanups (svsnick, a *line msg, kill, and some useless l_commands
code), suggested by Nazzy and Requi3m.
- Fixed extbans no longer working properly in CVS, fix provided by Nazzy (#0002681).
2005-11-09 14:29:32 +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 b5fd4a816f - Documented set::channel-command-prefix a bit more, and also changed the default from
"" to "!." which seems much more reasonable / widespread :).
2005-09-28 21:34:40 +00:00
Bram Matthys dc7554e227 - Changed the way we build most of the .so's: the .o files of individual modules that were
generated (for linkage by commands.so), are now used to generate the .so files of the
  individual modules as well (eg: m_setname.o -link-> m_setname.so). This reduces compile
  time ('make') on my machine by 33%, so it's quite noticable ;).
2005-09-26 22:57:44 +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 7ebd0debd7 - Fixed (important?) reference count bug regarding sptr->serv->conf. I don't know what
effects this caused (memory corruption?), but it didn't look good ;).
2005-09-12 16:33:46 +00:00
Bram Matthys 1023df3cd3 CMDLINE_CONFIG change & FAKELAG_CONFIGURABLE added:
- 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 ;)
2005-08-28 20:48:46 +00:00
Bram Matthys 4c3681afb9 another fix, for a slight variant 2005-08-28 19:13:51 +00:00
Bram Matthys 72910fafc9 - (5 minutes later..) Small update for above, fix was incorrect for ipv6. 2005-08-28 19:09:15 +00:00
Bram Matthys b1c4afdd41 - Fixed a bug where an invalid /*line could cause a crash, reported by Gilou (#2629). 2005-08-28 19:00:01 +00:00
Bram Matthys 0bc12e552c - Spamfilter: regexes (and reasons) are now more limited in size, this is to combat "I set
a spamfilter, but cannot remove it" problems. In practice this means - depending on the
  length of your spamfilter reason - regexes will be max ~300 characters.
  Spamfilters set in the .conf can be slightly longer (which still causes them to be
  truncated in '/stats f', but they don't have to be removed anyway so it's kinda
  acceptable if it's really needed). This should fix bug #2083, reported by White_Magic.
2005-08-28 16:28:40 +00:00
Bram Matthys 247e2ea6d5 - Temporary workaround for spamfilter bug: action 'viruschan' in combination with the
'u' (user) target can cause severe problems (crashes, etc). For now, we have disabled
  'viruschan' in combination with 'u'. A real fix will require quite some work, sorry.
2005-08-19 15:55:06 +00:00
Bram Matthys b340844aed - Fixed ~c not working properly with * and ?'s in channel names.. Now you just need to
escape them like in all bans (eg: to ban #* you need to +b ~c:#\*). As an additional
  bonus, real wildcards are now accepted and processed (eg: +b ~c:#*sex*, just don't
  forget to specify the #). Reported by PhantasyX (#2605).
- Sidenote on above: ~c:*chan* is not supported (use ~c:#*chan* instead) because it would
  cause "hidden bans", therefore it now prints a message (which is useful anyway), but
  does accept such remote bans. In 3.2.5 or so we could enable support for it, it's
  not that important though... ;)
- Added ifdefs for mass closing of file descriptors on start, can now be disabled by
  adding -DNOCLOSEFD as a compile option. Useful for valgrind w/--db-attach=yes, mpatrol,
  and some other debugging tools (not useful for anyone normally running a server).
- Fixed a read-after-free: sptr->serv->aconf was freed but not NULL'ed in exit_client,
  causing close_connection to read from it (when deciding on doing a quick reconnect).
  Could have caused a crash, although nobody ever reported one...
- Removed useless strncpyzt with dest==src.
2005-08-19 15:14:30 +00:00
Bram Matthys 10458c06b9 - Fixed problem with crash-on-link if compiled with GCC 4, reported by jonneyboy (#2573)
and PHANTOm (#2590).
2005-07-25 19:16:16 +00:00
Bram Matthys 50ceda48d2 - Added some TSCTL logging (this reminds me we need to add new log levels for 3.3 ;p).
- Attempt to fix bug #2431: 3.2.2 broke CNAME delegation for reverse dns. I'm sorry it took
  so long, but this stuff just plain sucks...
2005-07-05 19:14:58 +00:00
Bram Matthys 08954beb0d -extern MODVAR int badclass; <-- unused var 2005-06-12 18:56:44 +00:00
Bram Matthys 3efb800947 - Fixed 2 problems caused by TKL move: 1 windows crash, 1 problem with loading m_*.so,
reported by Trocotronic (#0002553, #0002554).
2005-06-07 14:06:48 +00:00
Bram Matthys d4f27c1183 - Fixed various major bugs due to TKL move from 13h ago. 2005-06-05 14:11:40 +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 5fcd80e11f - Fixed a TKL crash on incorrect *line, reported by nanookles1234 (#0002524).
- 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).
2005-05-26 20:18:07 +00:00
Bram Matthys 34ec08348c - /SAMODE could cause 'fishy timestamp' if digit parameters were used (eg: SAMODE #chan +l 5),
this has now be fixed by sending an explicit TS 0.
2005-03-10 01:29:30 +00:00
