+
+ngIRCd CVSHEAD
+
+ - Fixed a bug that could cause the damon to crash when outgoing server
+ connections can't be established.
+ - Internal: Simplified resolver code.
+ - Fixed a bug that caused the daemon to leak file descriptors when no
+ resolver subprocesses could be created.
+ - JOIN now supports more than one channel key at a time.
+ - Implementec numeric "333": Time and user name who set a channel topic.
+ - Fixed server NOTICEs to users with "s" mode ("server messages").
+ - Enhanced the handler for PING and PONG commands: fix forwarding and enable
+ back-passing of a client supplied additional argument of PING.
+ - Changed handling of timeouts for unregistered connections: don't reset
+ the counter if data is received and disconnect clients earlier.
+ - Fixed a format string bug in "connection statistics" messages to clients.
+ - Removed unnecessary #define of "LOCAL", now use plain C "static" instead.
+ - Channel topics are no longer limited to 127 characters: now the only limit
+ is the maximum length of an IRC command, i. e. 512 bytes (in practice, this
+ limits the topic to about 490 characters due to protocol overhead).
+ - Reverse DNS lookup code now checks the result by doing an additional
+ lookup to prevent spoofing.
+ - Added new IO layer which (optionally) supports epoll() and kqueue() in
+ addition to the select() interface.
+
+ngIRCd 0.9.1 (2005-08-03)
+
+ - The KILL command killed much more than desired (including server links!)
+ when the target user is connected to a remote server. Bug introduced in
+ ngIRCd 0.9.0 ... Reported by <qssl@fastmail.fm>, Thanks!
+ - Changed some constants to be "signed" (instead of unsigned) to solve
+ problems with old (pre-ANSI) compilers.
+
+ngIRCd 0.9.0 (2005-07-24)
+
+ ngIRCd 0.9.0-pre1 (2005-07-09)
+ - Fixed maximum length of user names, now allow up to 9 characters.
+ - Cut off oversized IRC messages that should be sent to the network instead
+ of shutting down the (wrong) connection.
+ - Don't generate error messages for unknown commands received before the
+ client is registered with the server (like the original ircd).
+ - Never run with root privileges but always switch the user ID.
+ - Make "netsplit" messages RFC compliant.
+ - Fix handling of QUIT Messages: send only one message, even if the client
+ is member of multiple channels.
+ - Don't exit server if closing of a socket fails; instead ignore it and
+ pray that this will be "the right thing" ...
+ - Implemented the IRC function "WHOWAS".
+ - Don't enable assert() calls when not ./configure'd with --enable-debug.
+ - Fixed ./configure test for TCP Wrappers: now it runs on Mac OS X as well.
+ - Enhanced configure script: now you can pass an (optional) search path
+ to all --with-XXX parameters, e. g. "--with-ident=/opt/ident".
+ - Removed typedefs for the native C datatypes.
+ Use stdbool.h / inttypes.h if available.
+ - New configuration option "OperServerMode" to enable a workaround needed
+ when running an network with ircd2 servers and "OperCanUseMode" enabled
+ to prevent the ircd2 daemon to drop mode changes of IRC operators.
+ Patch by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+ - Implemented support for "secret channels" (channel mode "s").
+ - New configuration option "Mask" for [Operator] sections to limit OPER
+ commands to users with a specific IRC mask. Patch from Florian Westphal.
+ - Write "error file" (/tmp/ngircd-XXX.err) only if compiled with debug
+ code ("--enable-debug") and running as daemon process.
+ - Don't create version information string each time a client connects
+ but instead on server startup. By Florian Westphal.
+ - New configuration variable "PidFile", section "[Global]": if defined,
+ the server writes its process ID (PID) to this file. Default: off.
+ Idea of Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+ - Code cleanups from Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+ - Raised the maximum length of passwords to 20 characters.
+ - Fixed a memory leak when resizing the connection pool and realloc()
+ failed. Now we don't fall back to malloc(), which should be sane anyway.
+ Patch from Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+ - Added support for the Howl (http://www.porchdogsoft.com/products/howl/)
+ Rendezvous API, in addition to the API of Apple (Mac OS X). The available
+ API will be autodetected when you call "./configure --with-rendezvous".
+ - Made ngIRCd compile on HP/UX 10.20 with native HP pre-ANSI C compiler and
+ most probably other older C compilers on other systems.
+ - When the daemon should switch to another user ID (ServerID is defined in
+ the configuration file) and is not running in a chroot environment, it
+ changes its working directory to the home directory of this user. This
+ should enable the system to write proper core files when not running with
+ root privileges ...
+
+ngIRCd 0.8.3 (2005-02-03)
+
+ - Fixed a bug that could case a root exploit when the daemon is compiled
+ to do IDENT lookups and is logging to syslog. Bug discovered by CoKi,
+ <coki@nosystem.com.ar>, thanks a lot!
+ (http://www.nosystem.com.ar/advisories/advisory-11.txt)
+
+ngIRCd 0.8.2 (2005-01-26)
+
+ - Added doc/SSL.txt to distribution.
+ - Fixed a buffer overflow that could cause the daemon to crash. Bug found
+ by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+ - Fixed a possible buffer underrun when reading the MOTD file. Thanks
+ to Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+ - Fixed detection of IRC lines which are too long to send. Detected by
+ Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+ - Fixed return values of our own implementation of strlcpy(). The code has
+ been taken from rsync and they fixed it, but we didn't until today :-/
+ It has only been used when the system didn't implement strlcpy by itself,
+ not on "modern" systems. Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+
+ngIRCd 0.8.1 (2004-12-25)
+
+ - Autoconf: Updated config.guess and config.sub
+ - Added some more debug code ...
+ - Fixed wrong variable names in output of "ngircd --configtest".
+ - Debian: Fixed the name of the "default file" in the init script for
+ ngircd-full packages. And do the test if the binary is executable after
+ reading this file.
+ - Enhanced the "test suite": please have a look at src/testsuite/README!
+
+ngIRCd 0.8.0 (2004-06-26)
+
+ - Fixed wrong buffer size calculation for results of the resolver.
+
+ ngircd 0.8.0-pre2 (2004-05-16)
+ - Enhanced logging to console when running in "no-detached mode": added
+ PID and log messages of resolver sub-processes.
+ - Fixed host name lookups when using IDENT user lookups.
+ - "make clean" and "make maintainer-clean" remove more files now.
+
+ ngIRCd 0.8.0-pre1 (2004-05-07)
+ - Two new configuration options: "ChrootDir" and "MotdPhrase", thanks to
+ Benjamin Pineau <ben@zouh.org>. Now you can force the daemon to change
+ its root and working directory to something "safe". MotdPhrase is used
+ to define an "MOTD string" instead of a whole file, useful if the
+ "real" MOTD file would be outside the "jail".
+ - INVITE- and BAN-lists become synchronized between IRC+ servers when
+ establishing new connections, if the peer supports this as well.
+ - Reorganized autogen.sh and configure scripts.
+ - Fixed a wrong assert() which could cause the daemon to exit spuriously
+ when closing down connections.
+ - Better logging of decompression errors returned by zlib.
+ - Servers other than the destination server didn't clean up the invite
+ list of an "invite-only" channel properly when an INVITE'd user joined.
+ - Changed the reply of the MODE command to match the syntax of the
+ original ircd exactly: the unnecessary but missing ":" before the last
+ parameter has been added.
+ - Fixed TRACE: don't output "Serv" lines for ourself; display more info.
+ - Results of the resolver (hostnames and IDENT names) are discarded after
+ the client is successfully registered with the server.
+ - Better logging while establishing and shutting down connections.
+ - The type of service (TOS) of all sockets is set to "interactive" now.
+ - Added short command line option "-t" as alternative to "--configtest".
+ - Added optional support for "IDENT" lookups on incoming connections. You
+ have to enable this function with the ./configure switch "--with-ident".
+ The default is not to do IDENT lookups.
+
+ngIRCd 0.7.7 (2004-02-05)
+
+ - The info text ("real name") of users is set to "-" if none has been
+ specified using the USER command (e. g. "USER user * * :"). Reason:
+ the original ircd doesn't like empty ones and would KILL such users.
+ - Fixed (optional) TCP Wrapper test which was broken and could result in
+ false results. Thanks to Fuminori Tanizaki <tany@mcnet.ad.jp>!
+ - Removed "USE_" prefixes of configuration #defines.
+
+ngIRCd 0.7.6 (2003-12-05)
+
+ - Fixed abort() ("server crash") when INVITE'ing users to nonexistent
+ channels. Bug found by <hiddenx@wp.pl>.
+ - Extended version numbering of CVS versions (added date).
+ - Enhanced/fixed doc/Protocol.txt;
+
+ngIRCd 0.7.5 (2003-11-07)
+
+ - Fixed ban behavior: users which are banned from a channel can't no
+ longer send PRIVMSG's to this channel (fixes Bug #47).
+ - Fixed and enhanced the "penalty handling" of the server: commands that
+ require more resources block the client for a short time.
+ - Changed the internal time resolution to one second.
+ - New configuration variable "MaxConnectionsIP" to limit the number of
+ simultaneous connections from a single IP that the server will accept.
+ This configuration options lowers the risk of denial of service attacks
+ (DoS), the default is 5 connections per client IP.
+ - Fixed build problems under Mac OS X 10.3.
+ - Use "-pipe" when compiling with gcc, speeds things up a little :-)
+ - Added new configuration variable "Listen" to bind all listening
+ sockets of the server to a single IP address.
+ - Suppress misleading error message of diff during make run.
+ - Enhanced test-suite and made it work on GNU/Hurd.
+ - Fixed minor typo in debug output :-)
+
+ngIRCd 0.7.1 (2003-07-18)
+
+ - Included files to build Debian packages (located in "debian/").
+ - Updated config.guess and config.sub to newer upstream versions.
+ - NJOIN propagates user channel modes correctly again ... Upsa.
+ - Made Makefile more compatible with "make -j<n>".
+ - Added support for GNU/Hurd.
+ - Fixed a compiler warning related to an unnecessary assert().
+ - Enhanced VERSION command when using debug versions.
+
+ngIRCd 0.7.0 (2003-05-01)
+
+ - "ServerName" is checked better now: a dot (".") is required.
+ - The KILL command verifies and logs more parameters.
+
+ ngIRCd 0.7.0-pre2 (2003-04-27)
+ - CVS build system fixes (made autogen.sh more portable).
+ - Fixed compilation and test-suite on Solaris (tested with 2.6).
+ - New documentation file "doc/Platforms.txt" describing the status of
+ ngIRCd on the various tested platforms.
+ - Test for broken GCC on Mac OS X and disable "-pedantic" in this case.
+ - Disable "-ansi" on Cygwin: system headers are incompatible.
+ - The server tried to connect to other servers only once when DNS or
+ socket failures occurred.
+ - Fixed --configtest: There is no variable "ServerPwd", it's "Password".
+
+ ngIRCd 0.7.0-pre1 (2003-04-22)
+ - New signal handler (more secure, actions are executed outside).
+ - GCC: the compiler is now called with more warning options enabled.
+ - Replaced a lot of str[n]cpy(), str[n]cat() and sprintf() calls with the
+ more secure functions strlcpy(), strlcat() and snprintf(). On systems
+ that don't support strlcpy() and strlcat(), these functions are included
+ in the libngportab now (with prototypes in portab.h).
+ - If the server can't close a socket, it panics now. This is an error that
+ can't occur during normal operation so there is something broken.
+ - The order of log messages during disconnects is more "natural" now ;-)
+ - Cleaned up handling of server configuration structures: modifying and
+ removing servers during runtime works more reliable now.
+ - Compression code from "conn.[ch]" is now found in new "conn-zip.[ch]"
+ - Moved some connection functions from "conn.[ch]" to "conn-func.[ch]".
+ - New command CONNECT to enable and add server links. The syntax is not
+ RFC-compatible: use "CONNECT <name> <port>" to enable and connect an
+ configured server and "CONNECT <name> <port> <host> <mypwd> <peerpwd>"
+ to add a new server (ngIRCd tries to connect new servers only once!).
+ - Added DISCONNECT command ("DISCONNECT <name>") to disable servers.
+ - Restructured the documentation: Now the main language is English. The
+ german documentation has been removed (until there is a maintainer).
+ - Enhanced killing of users caused by a nickname collision.
+ - Better error detection for status code ("numerics") forwarding.
+ - Moved tool functions to own library: "libngtool".
+ - New command TRACE (you can trace only servers at the moment).
+ - New command HELP that lists all understood commands.
+ - There should no longer remain "unknown connections" (see e.g. LUSERS)
+ if an outgoing server link can't be established.
+ - Added AC_PREREQ(2.50) to configure.in for better autoconf compatibility.
+ - Conn_Close() now handles recursive calls for the same link correctly.
+ - ngIRCd can register itself with Rendezvous: to enable support pass the
+ new switch "--with-rendezvous" to configure.
+ - Added support for TCP Wrappers library: pass "--with-tcp-wrappers" to
+ configure to enable it.
+ - Changed some configure options to use "--with"/"--without" as prefix
+ instead of "--enable"/"--disable": "--without-syslog", "--without-zlib",
+ "--with-tcp-wrappers", and "--with-rendezvous".
+ - Better error reporting to clients on connect.
+ - Enhanced manual pages ngircd(8) and ngircd.conf(5).
+ - Documentation is now installed in $(datadir)/doc/ngircd.
+ - Enhanced hanling of NJOIN in case of nick collisions.
+
+ngIRCd 0.6.1, 2003-01-21
+
+ - Fixed KILL: you can't crash the server by killing yourself any more,
+ ngIRCd no longer sends a QUIT to other servers after the KILL, and you
+ can kill only valid users now.
+ - The server no longer forwards commands to ordinary users, instead it
+ answers with the correct error message ("no such server") now.
+ - WHOIS commands weren't always forwarded as requested.
+ - The server sets a correct default AWAY message now when propagating
+ between servers (bug introduced in 0.6.0).
+ - Fixed up and enhanced CHANINFO command: channel keys and user limits
+ are synchronized between servers now, too.
+ - MODE returns the key and user limit for channel members correctly now.
+ - Non-members of a channel could crash the server when trying to change
+ its modes or modes of its members.
+ - The server didn't validate weather a target user is a valid channel
+ member when changing his channel user modes which could crash ngIRCd.
+
+
+Older changes (sorry, only available in german language):
+
+ngIRCd 0.6.0, 2002-12-24
+
+ ngIRCd 0.6.0-pre2, 2002-12-23
+ - neuer Numeric 005 ("Features") beim Connect.
+ - LUSERS erweitert: nun wird die maximale Anzahl der lokalen und globalen
+ Clients, die dem Server bzw. im Netzwerk seit dem letzten (Re-)Start
+ dem Server gleichzeitig bekannt waren, angezeigt.
+
+ ngIRCd 0.6.0-pre1, 2002-12-18
- beim Schliessen einer Verbindung zeigt der Server nun vor dem ERROR
noch eine Statistik ueber die empfangene und gesendete Datenmenge an.
- - Clients werden beim Connect mit NOTICEs ueber den Status der Resolver-
- Subprozesse informiert.
- - NOTICEs vom Server selber (z.B. Verbindungsstatistik oder s-Mode)
- haben nun ein "Text-Prefix": "*** ".
- der Server wartet bei einer eingehenden Verbindung nun laenger auf den
Resolver (4 Sekunden), wenn das Ergebnis eintrifft setzt er aber den
Login sofort fort (bisher wurde immer mind. 1 Sekunde gewartet).
- Connection-Strukturen werden nun "pool-weise" verwaltet; der Pool wird
bei Bedarf bis zu einem konfigurierten Limit vergroessert.
- - Mit der neuen Konfigurationsvariable "MaxConnections" (Sekion "Global")
+ - Mit der neuen Konfigurationsvariable "MaxConnections" (Sektion "Global")
kann die maximale Anzahl gleichzeitiger Verbindungen begrenzt werden.
Der Default ist -1, "unlimitiert".
- der Server erkennt nun, ob bereits eine eingehende Verbindung von einem
ausgehende Verbindung zu diesem auufzubauen. Dadurch kann nun auf beiden
Servern in der Konfiguration ein Port fuer den Connect konfiguriert
werden (beide Server versuchen sich dann gegenseitig zu connectieren).
+ - Test-Suite und Dokumentation an A/UX angepasst.
+ - unter HP-UX definiert das configure-Script nun _XOPEN_SOURCE_EXTENDED.
+ - Server identifizieren sich nun mit asyncronen Passwoertern, d.h. das
+ Passwort, welches A an B schickt, kann ein anderes sein als das, welches
+ B als Antwort an A sendet. In der Konfig.-Datei, Abschnitt "Server",
+ wurde "Password" dazu durch "MyPassword" und "PeerPassword" ersetzt.
+ - Der Server kann nun zur Laufzeit die Konfiguration neu einlesen: dies
+ macht er nach dem Befehl REHASH oder wenn ein HUP-Signal empfangen wird.
+ - Channel-Mode "P" ("persistent") kann nur noch von IRC-Operatoren gesetzt
+ werden. Grund: User koennen den Server sonst leicht "Channel-Flooden".
+ - MOTD kann nun an andere Server geforwarded werden.
+ - IRC-Befehl "TIME" implementiert.
+ - Server-Server-Links koennen nun komprimiert werden, dazu wird die zlib
+ (www.zlib.org) benoetigt. Unterstuetzt die Gegenseite die Komprimierung
+ nicht, wird automatisch unkomprimiert kommuniziert. Das Verfahren ist
+ kompatibel mit dem Original-ircd 2.10.3, d.h. beide Server koennen
+ miteinander ueber komprimiert Links kommunizieren.
+ - Handling der Schreibpuffer umgestellt: Server sollte schneller arbeiten.
+ - Prefix-Fehler werden besser protokolliert (mit verursachendem Befehl).
+ - SQUIT wird nicht mehr doppelt an andere Server weitergeleitet.
+ - Der Server versucht nun vor dem Schliessen einer Verbindung Daten, die
+ noch im Schreibpuffer stehen, zu senden.
+ - Source in weiteres Modul "irc-info" aufgespalten.
+ - Konfigurationsvariablen werden besser validiert: Laengen, Zahlen, ...
+ - neuen Befehl STATS begonnen: bisher unterstuetzt wird "l" und "m".
+ - bei ISON und USERHOST fehlte im Ergebnis-String der korrekte Absender.
+ - IRC Operatoren koennen nun mit KILL User toeten. Achtung: ein Grund muss
+ zwingend als zweiter Parameter angegeben werden!
+ - neue Konfigurations-Variable "MaxJoins": Hiermit kann die maximale Zahl
+ der Channels, in denen ein User Mitglied sein kann, begrent werden.
+ - neuer, deutlich flexiblerer Parser fuer den MODE Befehl.
+ - neue Channel-Modes l (User-Limit) und k (Channel-Key) implementiert.
+
+ngIRCd 0.5.4, 24.11.2002
+
+ - Fehler-Handling von connect() gefixed: der Server kann sich nun auch
+ unter A/UX wieder zu anderen verbinden.
- in den Konfigurationsvariablen ServerUID und ServerGID kann nun nicht
nur die numerische ID, sondern auch der Name des Users bzw. der Gruppe
verwendet werden. Beim Start des Daemons wird nun beides angezeigt.
- - Fehler-Handling von connect() gefixed: der Server kann sich nun auch
- unter A/UX wieder zu anderen verbinden.
- - Test-Suite an A/UX angepa§t.
+ - Besseres Logging von Prefix-Fehlern.
+ - angenommene Sockets werden nun korrekt auf "non-blocking" konfiguriert,
+ beim Senden und Empfangen werden Blockierungen besser abgefangen.
+ - RPL_UMODEIS hat Code 221, nicht 211 ... *argl*
+ - select() in Try_Write() hat falschen (keinen!) Timeout verwendet;
+ die "Zeit-Aufloesung" des Servers sind zudem nun 2 Sekunden (TIME_RES).
+ Insgesamt sollte die Reaktionszeit des Server nun besser sein.
