Bram Matthys 2a5ea10453 Lots of changes again. Most notable: Cmdoverride -> CommandOverride,
including things like CallCmdoverride() to CallCommandOverride().
Type changes like aTKline -> TKL and many more (in particular
aSomething to Something etc. such as aWatch to Watch) but these are
less used by 3rd party module coders.
2019-09-11 10:20:00 +02:00
Bram Matthys 23116d344a Give structs the same name as the typedefs. Rename aClient to Client,
aChannel to Channel, and some more. Third party module coders will
love this. But.. it makes things more logical and the doxygen output
will look more clean and logical as well.
(More changes will follow)

Bram Matthys d434cf948b Get rid of bcmp/bcopy/bzero. 2019-09-09 14:41:40 +02:00
Bram Matthys 0c4502bf79 Define and use SIPHASH_KEY_LENGTH rather than some magic value. 2019-09-08 14:15:23 +02:00
Bram Matthys 7ff78b4cf6 Make config test for except ban::type. Also use 'connect-flood'
rather than throttling, since that's the term we use everywhere
in our documentation and for config options.
2019-09-02 20:14:48 +02:00
Bram Matthys 58618bf2b6 Add support for ban exceptions, via /ELINE and via the config file.
Still need to fix some FIXME/TODO items and things haven't been
fully tested yet, so server sync issues or crashes are still possible.
Release notes will be updated another day as well..

Bram Matthys e8f336622a u_int64_t -> uint64_t 2019-06-26 17:03:07 +02:00
Bram Matthys 709c84fff9 Remove stupid hash table layer for channels that only eats 256k+ extra
memory and causes unnecessary slowdown. Stupid ->hits and ->links.
And get rid of "return (xyz)", must be "return xyz" :D
2019-06-26 16:56:17 +02:00
Bram Matthys f1b0b6b76e Make throttling code (connect-flood) use SipHash and increase the
hash table size from 1019 to 8192 to have fewer collisions.
2019-06-26 16:46:28 +02:00
Bram Matthys eafd929e24 Update DNS code to use SipHash 2019-06-26 14:08:03 +02:00
Bram Matthys 703be7eb29 Move some functions from parse.c to hash.c and add documentation
for various functions, such as find_person, find_client, etc.
2019-06-26 13:57:06 +02:00
Bram Matthys f6eac29592 hash_nick_name -> hash_client_name, hash_find_nickserver -> hash_find_nickatserver
Both were confusing :)
2019-06-26 13:45:55 +02:00
Bram Matthys d5b643ceee Rewrite hash table code to use SipHash (more to follow) 2019-06-26 13:24:02 +02:00
Bram Matthys 7161f33311 Code cleanup: make src/*.c use the generic #include "unrealircd.h" file
(with only a few exceptions)
Now, we'll find out later if Windows still compiles, I guess ;)

Bram Matthys 6990b7d9a6 Mass-replace MyMalloc with MyMallocEx, even if it's unnecessary.
Replace century-old custom functions with C standard funcs,
such as AllocCpy -> strdup.
2018-04-22 14:55:07 +02:00
Bram Matthys d5d446c38d More code cleanups to get rid of useless casts and other useless
structures such as:
-       lp->value.cp = (char *)MyMalloc(strlen(mask) + 1);
-       (void)strcpy(lp->value.cp, mask);
+       lp->value.cp = strdup(mask);

Bram Matthys b072a80638 get rid of local->ip stuff in throttle 2015-07-28 17:47:40 +02:00
Bram Matthys 80147b2914 Make throttling code work on aClient * structs. Other code may change later (makes it easier). 2015-07-28 14:05:41 +02:00
Bram Matthys 58b864edd5 Re-do CIDR and at the same time all the user matching stuff. Introducing match_user(mask, acptr, options): this should be used everywhere rather than the many DIY routines everywhere that create a nick!user@host and then run a match() on it.
The match_user() function is not been fully tested yet, at this point I'm happy we can compile again.
2015-07-28 13:26:03 +02:00
Bram Matthys 13fffa4e1a split all the local client stuff to acptr->local. makes it a lot easier to catch bugs.
If the IRCd crashes then it's likely not by this change but rather an existing issue that was previously gone unnoticed.

Bram Matthys 252538272e Reduce nick@server complexity in m_message and (similarly) make hash_find_nickserver() easier and more tolerant, also accepts just 'nick' in addition to 'nick@server' 2015-07-16 18:09:26 +02:00

Bram Matthys 61cfb5ac3e - Windows: Fix strange linking bug. Outgoing connects from a Windows
IRCd caused a garbled SERVER protocol message, causing 'cannot find
  server' errors and killing of users. Reported by Sunkat (#4183).

William Pitcock ec09c447e5 - Remove defines FAST_BADWORDS_REPLACE, THROTTLING, EXTCMODE. (#2937)
The code does not compile without them anyway.
2012-11-25 17:45:45 +00:00
William Pitcock 9853fa54f4 - Rework the client management code to use a circular queue and set of
circular queues for hashtable.
2012-11-21 22:49:32 +00:00
Bram Matthys 51d30af3fd - Applied patch from k4be (#0003866) which introduces a new packet hook
(HOOKTYPE_PACKET). Replacing the 'text to be sent' to a client is
  supported, which allows character(set) conversion in a module.
  Note that modifying an incoming message by the hook is not supported.
2009-11-22 12:10:56 +00:00
Bram Matthys 8918b99248 - Throttling time is now more accurate, especially with larger time values
such as 3 connections per 60 seconds. Previously that could result in 3
  per 90 seconds due to timer inaccuracy, now max 65 seconds (max 5s
  inaccuracy).

Bram Matthys 7c400e7dc1 - Ok, finished away notification in WATCH. It now shows the away reasons too.
This new feature (away notify) is announced in 005 (ISUPPORT) as: WATCHOPTS=A

  Format is: WATCH A +UserOne +UserTwo

  New numerics to cope with away notification in WATCH are:
  RPL_NOWISAWAY: to indicate the user is away _when adding_ it to WATCH list
  RPL_GONEAWAY:  user was not away, but is now
  RPL_NOTAWAY:   user was away, but is no longer away
  RPL_NOWISAWAY: user was away, and still is, but the reason changed
  Example:

  WATCH A +Target
  Request to add user 'Target' to the watch list with away notification

  :maintest.test.net 609 MySelf Target ~blih test.testnet 1204309588 :not here atm
  Reply to watch add: user is online and away, reason is provided

  :maintest.test.net 599 MySelf Target ~blih test.testnet 1204309588 :is no longer away
  User is back (no longer away)

  :maintest.test.net 598 MySelf Target ~blih test.testnet 1204309722 :lunch
  State change: user is now away, reason is provided

  :maintest.test.net 597 MySelf Target ~blih test.testnet 1204309738 :shopping, bbl
  User is still away, but reason changed.

  The syntax for each numeric is:
  <nickname> <username> <hostname> <awaysince> :<away reason>
  In case of 599 (RPL_NOTAWAY) it is:
  <nickname> <username> <hostname> <awaysince> :is no longer away

  For the record, this is all based on a draft from codemastr from 2004, which was
  implemented in Unreal3.3 (devel branch) in 2006. Today, in 2008 it was updated
  with away reason support and backported to Unreal3.2. Because away notification
  hasn't been used until now (due to it only being in Unreal3.3) we felt it was
  safe to break some numerics.
2008-02-29 18:44:07 +00:00
Bram Matthys 635ab4858e - Backport from 3.3 away notification from Oct 2006, this is v0, a further
patch will follow soon and the numerics will be changed.

Bram Matthys d6fd665ede - Multiple /module changes (the command):
- Normal users can now get a list, versioninfo will be hidden however.
  - Opers get some additional details like hooks and commandoverride's.
  - Opers can use /module <servername> to get a remote list of loaded modules.
  - Added flag [3RD] to show it's a 3rd party module
  This was requested by by quite some people because serveradmins started to load
  "spy modules" without clearly mentioning it in the MOTD (which is highly unethical
  and in some countries even illegal due to privacy law). Also the remote module
  list was requested by quite a few opers.
  Sure, this isn't a 100% guarantee but at least if someone goes hiding stuff
  then it's clear what their intentions are (and thus will be refused support, ..).
- Changed emailaddr in help window at windows to unreal-users mailinglist.
- Made the cloak mismatch msg during linking a bit more scary.
- Added comment to 'Install as a service' option in installer to help n00bs a bit.

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.

Bram Matthys 2d0abfa787 - Enabled throttling support by default, you need to have a (correct) set::throttle block to make it work, otherwise it's just turned off. 2003-04-24 01:21:52 +00:00
