ngIRCd 0.11.1. (tags/rel-0-11-1)
From: Rolf Eike Beer <eike@sf-mail.de>
Fix sending of JOINs between servers I found a bug in "sending join between servers". This does hit only operators that join a channel with at least 2 servers active in the net the server the oper connects to sends "channel^Go" to the other servers the other server first searches for the channel and then strips the modes from the channel name he has to do the other way round: first strip and then check the channel name.
send "G" flag in WHOIS replies instead of "H" if client is marked as being away.
(reported by Dana Dahlstrom)
From: Dana Dahlstrom <dana+70@cs.ucsd.edu>
Under some circumstances ngIRCd currently issues a channel MODE message with a trailing space after the last parameter, which isn't permitted by the grammar in RFC 2812 section 2.3.1: http://tools.ietf.org/html/rfc2812#section-2.3.1 The following patch modifies mode-test.e to expose this, and modifies irc-mode.c to correct it. [from HEAD]
[Parser]: Don't use Client_Type after command has been processed.
This caused a read from already free'd memory, if the processed command (IRC_QUIT) calls Client_Destroy. (from HEAD)
[LOGIN] irc_login, w CVSDATE defined, used strncpy with overlapping src/dest.
use memmove instead (from HEAD).
ngIRCd 0.11.0 (tags/rel-0-11-0)
ngIRCd 0.11.0-pre2 (tags/rel-0-11-0-pre2)
kqueue: check for EV_ERROR in .flags
if kevent() returns events, check for EV_ERROR in event flags, too.
include <arpa/inet.h> inside tool.h
In file included from hash.c:24: ../tool/tool.h:27: warning: `struct in_addr' declared inside parameter list
remove ip-string from Conf_Server struct
struct Conf_Server stored the ip address to connect to in dotted-decimal notation; but we only need this for connect() so long-time storage isn't necessary.
bind ListenAddress for outgoing connections
ngircd would always use INADDR_ANY for outgoing connections; which might not be desirable. Added new [Server] option "Bind" to set source ip.
Introduce option to configure the maximum nick name lenth in ngircd.conf
- New configuration option "MaxNickLength" to specify the allowed maximum length of user nick names. Note: must be unique in an IRC network! - Enhanced the IRC+ protocol to support an enhanced "server handshake" and enable server to recognice numeric 005 (ISUPPORT) and 376 (ENDOFMOTD). See doc/Protocol.txt for details.
Fixes the wrong logging output when nested servers are introduced
to the network as well as the wrong output of the LINKS command.
Update Mac OS X Xcode project file for Xcode 3.
Allow building of ngIRCd using Xcode 3 without running ./configure.
if ngircd doesn't run chrooted, it tries to chdir
to the users working directory (as returned by getpwuid()). Failing to chdir to that directory isn't an error; so log with LOG_INFO and prefix the message with "Notice".
configtest would still print "-1" for MaxConnections, MaxConnectionsIP and MaxJoins
if any of those values was set to 0.
accoring to comments in the code, MaxConnections, MaxConnectionsIP and MaxJoins
options allow setting values < 0 -- this isn't the case. Comments adjusted.
Updated preferred automake version to 1.9. Only set preferences if not
already defined by some environment variables.
SECURITY: Fixed a severe bug in handling JOIN commands, which could
cause the server to crash. Thanks to Sebastian Vesper, <net@veoson.net>.
- change return type of Conn_InitListeners to unsigned
- remove minor whitespace damage
New configure option "--without-select"; when usin epoll() IO API include
support for select() as well by default and fall back on runtime when needed.
predefined channels MUST start with '#', but this is not very intuitive,
since # is also used as a comment character in ngircd.conf. Thus we prefix the name with '#' if it is missing.
New configuration option "PredefChannelsOnly": if set, make
all JOINs to-non existants channel return ERR_BANNEDFROMCHAN_MSG, restricting users to those channels defined in the config file.
Allow PASS syntax defined in RFC 1459 for server links, too.
Removed client status CLIENT_GOTPASSSERVER.
only test for stack smashing protector if we are using gcc;
use -fstack-protector-all for the test to make sure the guard variable is added.
Flag the format parameter of LogDebug() as "unused" when not compiling with
debug code to avoid gcc warnings. Added some documentation comments.
Removed kqueue bug fix (never released), rephrased some internal changes,
and added "time shift" bug fix.
Moved now local prototype of Client_New() to C file, renamed it to
Init_New_Client() and cleaned up some code and comments.
Remove direct call of Conf_UnsetServer(): it's already indirectly called
by Conn_Close() a few lines above.
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.
The KILL command killed much more than desired (including server links!)
when the target user is connected to a remote server. [from 0.9.x]
Removed "U" unsignet suffix: caused problems with older compilers and is
not necessary for this constants.
New subdirectory "src" for the source code documentation, and new make
target "srcdoc" to generate the documentation using Doxygen.
Only setuid()/setgid() if it differs from current UID/GID.
Solves problems with Cygwin.
Don't exit server if closing of a socket fails; instead ignore it and
pray that this will be "the right thing" ...
Reformatted and documented code of the first part of the IRC_NICK()
function; and register WHOWAS entries on nickname changes, too.
Away status texts set due to "a"-Modes received from other servers have
been fixed: the status text of the server has been set instead of the away status text of the client (most probably introduced by patch 1.36).
Added #include of "defines.h", necessary due to removal of the #include of
"defines.h" in the client.h header file.
Reorder #includes, necessary due to removal of #include "defines.h" in
the client.h header file.
Removed "invalid" #include of "defines.h" (don't include further header
files from a header file!).
removed Conn_UnsetOption() function. It was not used anymore.
removed Conn_SetOption(). replaced its only call (in conn-zip.c) with Conn_OPTION_ADD() macro.
conn.h: option filed in CONNECTION struct is now UINT16.
conn-func.h: add accessor Macros Conn_OPTION_ADD( conn, CONN_OPTION ) Conn_OPTION_DEL( conn, CONN_OPTION ) Conn_OPTION_ISSET( conn, CONN_OPTION ) To add, remove or test for a certain option field attribute (e.g. CONN_ISCLOSING) These Macros should be used instead of accessing conn->options directly.
Target "lint": check whether splint command is available and suppress
warnings related to the used command line in the output.
Two new targets: "srcdoc" to generate Doxygen source documentation, and
"xcode" to build ngIRCd using the Xcode command line tools on Mac OS X.
New build style "deployment", cleaned up options for build style
"development" (enabled "ZeroLink") and fixed path of "ngircd.spec".
When validationg the configuration file wait for a keypress only if both
stdin and(!) stdout are valid tty's.
Enhanced configure script: now you can pass an (optional) search path
to all --with-XXX parameters, e. g. "--with-ident=/opt/ident".
Remove INT, LONG, BOOLEAN, STATIC, CONST, CHAR datatypes.
use stdbool.h / inttypes.h if available.
Updated to latest strl{cat|cpy} code of rsync:
- Make sure that strlcpy() returns the right value when the bufsize is 0. - Fixed a bug in strlcat() where it would not properly detect a no-change condition if called with an initial string longer than the specified size limit (due to an unsigned var's inability to go negative). Patch by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
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
insetead on server startup. By Florian Westphal.
Added an empty /etc/ngircd/ngircd.motd to the packages. And ngircd.conf
becomes modified to enable the PID file (/var/run/ircd/ngircd.cond) and to change the user and group to "irc".
New configuration variable "PidFile", section "[Global]": if defined,
the server writes its process ID (PID) to this file. Default: off. Idea by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
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)
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>.
Code cleanups from Florian Westphal, <westphal@foo.fh-furtwangen.de>:
wrote functions for common error messages.
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 :-/
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>.
Make more clear that there can be more than one [Operator], [Server] and
[Channel] section in the configuration file.
Added support for the Howl (http://www.porchdogsoft.com/products/howl/)
Rendezvous API, in addition to the API of Apple (Mac OS X).
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.
Fixed echo without newline for systems not understanding "echo -n"; added
new file "functions.inc" for functions usable by all test scripts.
Fxied name of "default file" for ngircd-full package. And do the test if
the binary is executable after reading this file.
Changed text "test scripts" to "processes": some versions of expect(1)
fork child processes ...
Added missing commas to debian control file, fixes bug #56.
Thanks to Kevin Otte (nivex@nivex.net) for the patch.
Added PID to all log messages on the console; enhanced logging of
resolver sub-processes in debug mode.
New "chroot" feature (from Benjamin Pineau), introducing new configuration
variables "ChrootDir" and "MotdPhrase".
Document new server flag "L": synchronize INVITE- and
BAN-lists when establishing new server links.
Synchronize INVITE- and BAN-lists if the peer requests it:
server flag "L". And better debug logging.
Don't send MODE changes when origin is a server and
mask is already known.
Fixed a wrong assert() which could cause the daemon to exit spuriously
when closing down connections.
Fixed handling of already existent entries in invite and ban lists:
the attempt to add an already existent entry is no error, it must be propagated across servers (but not added to the list!).
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.
Reworked configure system: it should be more compatible to most systems
now, and it should even be more flexible and faster :-)
Fixed some warnings of non-gcc-compilers (e. g. original Apple compiler on
A/UX): "warning: illegal pointer combination, op =".
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.
Better logging while establishing and shutting down connections.
Results of the resolver are now discarded after the client is registered.
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>!
Restructured debian packaging system: now there are two packages, a "standard"
version that includes all the default options and a "full" version that additionally includes support for TCP wrappers and IDENT lookups.
Removed outdated Mac OS X ProjectBuilder project files (will be re-added
and updated for XCode soon); moved the debian/ directory to contrib/Debian/.
Added some files to the maintainer-clean-local target which havn't beed
removed by "make maintainer-clean".
Fixed error messages related to server name configuration; updated
sample configuration file. (from 0.7.x)
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 penalty handling; changed internal time resoluiton of
the server to one second. Code cleanup.
Updated documentation. (tags/rel-0-7-0-pre1)
Added implicit initialisation of "i" in Conf_GetServer to workaround a egcs
2.91.66 bug which claims that this valiable could be used uninitialized.
Added some defines for Linux/glibc, reverted unused test for poll(), and
enhanced summary output.
Changed documentation directory to ".../share/doc/ngIRCd" (and removed the
variable PACKAGE for better Debian automake-1.4 compatibility).
Added support for TCP Wrappers; redesigned configuration result output;
Changed some "--enable"/"--disable" switches to "--with"/"--without".
The server didn't validate wheather the "target" client of a channel
user mode change is a valid channel member or not.
- Check functions only on systems that support prototypes, elder cpmpilers
become confused instead!
- Fixed up command forwarding: only to servers!
- Forwarding of WHOIS was broken in some situations.
- Changed "once"-server-config-flag into a generic flag.
- Changed semantics of "NGIRCd_Passive".
- New functions Conf_EnableServer(), Conf_DisableServer() and Conf_AddServer().
- Changed "once"-server-config-flag into a generic flag.
- New commands CONNECT and DISCONNECT.
- Validate operator status before syntax checks.
- If the server can't close a socket, it panics now.
- Quite enhanced logging :-)
- fixed KILL: you can kill yourself now without crashing the server;
QUIT isn't send to other servers after the KILL any more.
- renamed variables to fit new signal handler.
- moved call to NGIRCd_Rehash() to Conn_Handler().
- validate Conf_MaxConnections against FD_SETSIZE if available;
- fixed up some log messages and enhanced configuration validation.

- new file header format (in english);
- new file ident semantics.
- translated file header and comments to english;
- new file ident semantics.
- neue Befehle: Conn_StartTime(), Conn_SendQ(), Conn_RecvQ(), Conn_SendMsg(),
Conn_RecvMsg(), Conn_SendBytes[Zip](), Conn_RecvBytes[Zip]().
- beim Umschalten auf Kompression wurden evtl. bereits gelesene Daten nicht
entpackt, der Datenstrom war somit dann korrumpiert.
- neue Funktionen: Conn_SetOption(), Conn_UnsetOption(), Conn_Options().
- wenn mit zlib-Support: Conn_InitZip().
- volle Lesebuffer und Timeouts behandelt Conn_Handle() nun besser.
- Handle_Buffer() liefert nun ein Ergebnis.
- select() in Try_Write() hat falschen (keinen!) Timeout verwendet;
- der Timeout fuer das select() in Conn_Handler() ist nun TIME_RES (=2).
- RELOAD in REHASH umbenannt.
- neue Funktion WHOWAS.
- neue Meldungen: RPL_STATSLINKINFO, RPL_STATSCOMMANDS, RPL_ENDOFSTATS,
RPL_WHOWASUSER, RPL_ENDOFWHOWAS und ERR_WASNOSUCHNICK.
- Listen-Sockets werden ueber neue Funktion Conn_InitListeners() erzeugt.
- neue Funktion NGIRCd_Reload(). - Logging bei empfangenen Signalen verbessert. - SIGHUP ruft nun NGIRCd_Reload() auf.
- Befehle sortiert,
- neuer Befehl RELOAD.
- angenommene Socketes werden nun korrekt auf "non-blocking" gestellt;
- beim Senden und Empfangen wird EAGAIN ("Blockierung") nun abgefangen.
- unter HP-UX wird nun _XOPEN_SOURCE_EXTENDED definiert. Fuer den gcc
unter 11.11 ist dies erforderlich.
- Fehler-Handling von connect() gefixed: der Server kann sich nun auch
unter A/UX wieder zu anderen verbinden.
- in ServerUID und ServerGID kann nun jeweils auch der Name (und nicht nur
die numerische ID) verwendet werden.
- Neue Funktion Conn_SetServer().
- Einige assert()'s aufgeraumt.
- Connection-Strukturen werden nun "pool-weise" verwaltet; der Pool wird
bei Bedarf bis zu einem konfigurierten Limit vergroessert. - neue Funktionen Conn_First(), Conn_Next(), Conn_ClearFlags(), Conn_Flag() und Conn_SetFlag().
- ausgehende Verbindungen mit ID 0 konnten nicht aufgebaut werden ... :-/
- einige Debug-Ausgaben erweitert.
- Segfault unter hoher Netzaktivitaet behoben: in Conn_Close() wird die
Connection-Struktur nun frueher als "ungueltig" markiert. - besseres Error-Logging.
- Es wird nun laenger auf Resolver-Ergebnisse gewartet, der Login aber
sofort fortgesetzt, so ein Ergebnis eintrifft.
- "schneller Server-Reconnect" wird nun nur dann ausgefuehrt, wenn die
Verbindung zuvor "lange genug" aufgebaut war (z.B. also nicht mehr, wenn der Peer sofort beim Connect ein fatales ERROR liefert).
- Connection-Statistik implementiert.
- Server-NOTICEs haben nun ein "Text-Prefix".
- bei CVS-Versionen wird nun das Datum der letzten CVS-Aenderung angezeigt,
Versionsnummer entsprechend angepasst.
