Bram Matthys d4c9e0af27 - Added MINIMAL time synchronization support. This is enabled by default and will try to
synchronize the IRCd clock (TSOffset) with a few good time servers. It currently only does
  this on-boot, but it will hopefully help a lot of people with most of their time differences.
  I still keep recommending anyone who can to run proper time-synchronization software such as
  ntpd/ntpdate on their servers.
  To disable time synchronization (eg: because you are already running ntp), you can simply
  set set::timesynch::enabled to no.
  The boot timeout for the timeserver response (=causes boot delay) can be configured via
  set::timesynch::timeout and is set to 3 seconds by default (range is 1s-5s), there should
  be no reason to change this.
  The time server can be configured by setting set::timesynch::server, the default is to
  use 3 time servers on 3 continents (US, EU, AU) which should be sufficient for anyone but
  if you got a good one near you you can use that one instead.
  The time protocol we use is (S)NTP v4.

Bram Matthys 98cd2c254e - Added error checking to (main) setuid/setgid calls. 2006-05-05 23:02:11 +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).

Bram Matthys 3c529c7ee1 - Fixed CHROOTDIR compilation problem, reported by toshio (#0002854).
- Improved CHROOTDIR documentation in include/config.h
- Added error if CHROOTDIR is defined but IRC_UID isn't (in include/config.h).

Bram Matthys f24d4495a2 - Fixed (well, workaround) win32 /RESTART bug that caused it to popup a window instead
of actually restarting the server properly (#0002734).

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).

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).

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).

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).

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 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/

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).

Bram Matthys e6156b4604 - Added spamfilter 'away' ('a') target (#0002057). 2004-10-11 18:46:53 +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.

Bram Matthys 8702450af2 Various stuff:
- 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.

Bram Matthys 7c4418113b - Changed random number generator to use arc4random-alike routines so we can get "secure"
random numbers. We will also no longer be using rand()/random() anywhere.
  Thanks to dek\ for pointing out this is potentionally dangerous, especially on
  win32 with NOSPOOF enabled.

Bram Matthys 56cb95f189 - internal: Modified TKL system (getting ready for anti-spam system):
Instead of 1 big list of *lines, it's now an array to easily distinct between types.
  Also made tk->usermask static (USERLEN+2) instead of dynamic.
  These changes should give enough speed improvement to make the new anti-spam/anti-ads
  feature fast enough.
2004-01-01 22:53:50 +00:00
Bram Matthys 426fbd9663 - Added "extended bans". An idea from SorceryNet ircd.
These bans look like ~<type>:<stuff>. Currently the following bans are available:
  ~q: quiet bans (ex: ~q:*!*@blah.blah.com). People matching these bans can join
      but are unable to speak, unless they have +v or higher.
  ~c: channel bans (ex: ~c:#idiots). People in #idiots are unable to join the channel.
  ~r: gecos (realname) bans (ex: ~r:*Stupid_bot_script*). If the realname of a user
      matches this then (s)he is unable to join.
      NOTE: an underscore ('_') matches both a space (' ') and an underscore ('_'),
            so this ban would match 'Stupid bot script v1.4'.

  These bantypes can also be used in the channel exception list (+e).
  +e ~r:*w00t* makes anyone with 'w00t' in their realname able to join,
  and +e ~c:#admin makes anyone in #admin able to join, etc..

  This system allows modules to add extended bantypes too.

  This feature requires some additional testing, also the module interface will
  probably be changed in the next few weeks, and perhaps more extended bans will
  be added before next release.. we'll see...

Bram Matthys c25223913c - (Internal) Added __attribute__ format checking for most format string functions,
this will currently produce a lot of warnings with -Wall.
- Fixed 159 of 184 warnings detected by the above, the other warnings are false.
  Most warnings had to do with long vs int, and thus the format strings (%d->%ld)
  or the vars (int->long) have been changed (many of these were time_t/TS vs int).
  Only a few rare crashbugs were discovered.
- Module coders: for HOOKTYPE_LOCAL_CHANMODE the 'sendts' parameter was changed
  from type 'int' to 'time_t', while in most circumstances (like on ia32)
  you won't notice, I suggest you to update your callback functions anyway.
- Possibly fixed an issue with set::modes-on-join and mode +f, it could have
  set random remove-chanmode times in the default chanmode line.
2003-11-02 02:58:11 +00:00
Bram Matthys ad9d0370fa Added remove-chanmode-after-X-minutes in +f & checks for /sethost&/chghost to same host.
- Added checks for /sethost&/chghost to same host.
- Added remove-chanmode-after-X-minutes in +f.
  The format is +f [30j#R5]:15, where 5 is the "do -R after 5 minutes". For a default
  action like +i you would have to do the same: +f [30j#i5]:15 (remove 'i' after 5 minutes).
  Additionally, 2 config items are added:
  - set::modef-default-unsettime, if this is set to for example '5' then things like
    +f [30j]:15 will be transormed into +f [30j#i5]:15. It's just a default, the user can still
    override it. By default this feature is not used.
  - set::modef-max-unsettime, specifies the maximum amount of time for the <time> parameter,
    by default this is set to 60 (=1 hour), the value should be between 0 and 255.
  I didn't do the extended tests I usually do but it seems stable, also the docs are updated
  but are probably updated again later to make it a bit more readable.
  Feel free to report any bugs as soon as you discover them.
  The only thing I could think of is: _usually_ only 1 server will have the -i/-R/.. timer
  running, so if that server splits (or even worse dies) it will only be -i/-R/.. at that server
  and when they sync back they merge chanmodes so +i/+R is set again.
  I don't consider this a huge problem but maybe it can be inconveniently, if people have
  a lot of trouble with this I'll have to consider a 50% recode of the +f system :/.

Bram Matthys 8a4856fa8b Fixed MAJOR "messages are lost" caused by BUFFERPOOL being to low and bad return checking of dbuf_put.
If BUFFERPOOL dbuf_put would return -1, but at some places !dbuf_put was used,
I've changed it so it will return 0 (so use !dbuf_put now, don't use dbuf_put(...) < 0 :P).
I also added some nice warning thing. I couldn't send from the send routine because that's risky ;).
And...... I also doubled the default BUFFERPOOL, so if you leave everything the default then
BUFFERPOOL is now 52Mb instead of 26Mb, which should be ok for now.
