+ ngIRCd 27~rc1 (2024-04-13)
+ - Validate certificates on server links. Up to now, ngIRCd optionally used
+ SSL/TLS encrypted server-server links but never checked and validated any
+ certificates. Now ngIRCd validates SSL/TLS certificates on outgoing
+ server-server links by default and drops(!) connections when the remote
+ certificate is invalid (for example self-signed, expired, not matching the
+ host name, ...). Therefore you have to make sure that all relevant
+ *certificates are valid* (or to disable certificate validation on this
+ connection using the new `SSLVerify = false` setting in the affected
+ `[Server]` block, where the remote certificate is not valid and you can not
+ fix this issue).
+ The original patch for OpenSSL dates back to 2009 and was written by Florian
+ Westphal and was extended for GnuTLS in 2014 by Christoph Biedl. But it took
+ us another 10 years to bring it to life ... oh my! Many thanks to both
+ Florian and Christoph!
+ Closes #120.
+ - Add support for the "sd_notify" protocol of systemd(8): Periodically
+ "ping" the service manager (every 3 seconds) and set a status message
+ showing current connection statistics which then is included in "systemctl
+ status ngircd.service" output. In addition, this enables using the
+ systemd(8) watchdog functionality ("WatchdogSec") for the "ngircd.service"
+ unit and allows it to use the "notify" service type, which results in
+ better status tracking by the service manager.
+ - Try to set file descriptor limit to its maximum and show info on startup:
+ The number of possible parallel connections is limited by the file
+ descriptor limit of the process (among other things). Therefore try to
+ upgrade the current "soft" limit to its "hard" maximum (but limited to
+ 100000 instead of "infinite"), and show an information or even warning when
+ the limit is still less than the configured "MaxConnections" setting. Please
+ note that ngIRCd and its linked libraries (like PAM) need file descriptors
+ not only for incoming and outgoing IRC connections, but for reading files
+ and inter-process communication, too! Therefore the actual connection limit
+ is less(!) than the file descriptor limit!
+ - Update and fix the logcheck(8) rules file.
+ - METADATA: Fix unsetting the "cloakhost" hostname, which did not result in
+ the original hostname being restored, but actually resulted in an empty
+ string being used as the client hostname -- which is a protocol violation.
+ - Update the "rpm" make target to use the rpmbuild(8) command.
+ - Add a "Docker file" (contrib/Dockerfile) and corresponding documentation
+ (doc/Container.md) to the project. The resulting container is based on the
+ latest Debian "stable-slim" container and built using a "build container".
+ - Remove outdated, unsupported and broken support for splint(1).
+ - Don't show the default config file name on config errors: The configuration
+ can be set in drop-in files in the include directory, too, so it is not
+ clear in which file it is actually missing.
+ - No longer use a default built-in value for the "IncludeDir" directive when
+ a configuration file was explicitly specified on the command line using
+ "--config"/"-f": This way no default include directory is scanned when a
+ possibly non-default configuration file is used which (intentionally) did
+ not specify an "IncludeDir" directive. So now you can use "-f /dev/null"
+ for checking all built-in defaults, regardless of any local configuration
+ files in the default drop-in directory (which would have been read in
+ until this change).
+ - No longer log channel keys ("passwords") for predefined channels.
+ - The server "Name" in the "[Global]" section of the configuration file no
+ longer needs to be set: When not set (or empty), ngIRCd now tries to
+ deduce a valid IRC server name from the local host name ("node name"),
+ possibly adding a ".host" extension when the host name does not contain a
+ dot (".") which is required in an IRC server name ("ID").
+ This new behavior, with all configuration parameters now being optional,
+ allows running ngIRCd without any configuration file at all.
+ - Silence some compiler warnings.
+ - autogen.sh: Prefer automake 1.11 over other releases because this is the
+ last release supporting "de-ANSI-fication" using the included ansi2knr tool.
+ And because we _want_ to support old K&R platforms, we try hard to use this
+ release of automake when available to generate our build system.
+ Note: This is only relevant for you if you are building from Git sources.
+ - Autodetect support for IPv6 by default: Until now, IPv6 support was disabled
+ by default, which seems a bit outdated in 2024. Note: You still can pass
+ "--enable-ipv6"/"--disable-ipv6" to the ./configure script to forcefully
+ activate or deactivate IPv6 support.
+ - Do IDENT requests even when DNS lookups are disabled: Up to now disabling
+ DNS in the configuration disabled IDENT lookups as well (for no good
+ reason). Now you can activate/deactivate DNS lookups and IDENT requests
+ completely separately. Thanks for reporting this, Miniontoby!
+ Closes #291.
+ - Update config.guess (2023-08-22) and config.sub (2023-09-19) files.
+ - Fix Channel Admins being able to to set Channel Owner status! "Sarah"
+ reported this back in April 2021 and proposed a patch, thanks a lot!
+ - Test suite: Update for OpenSSL 3.x, some command outputs changed, clean up
+ shell scripts and make the getpid.sh script more robust.
+ - Allow SSL client-only configurations without keys/certificates: You don't
+ need to configure certificates/keys as long as you don't configure
+ SSL-enabled listening ports. This can make sense when you want to only link
+ your local daemon to an uplink server using SSL and only have clients on
+ your local host or in your fully trusted network, where SSL is not required.
+ - Remove the unmaintained contrib/MacOSX/ folder: this includes the Xcode
+ project as well as the outdated macOS "Package Maker" configuration. The
+ sample launchd(8) configuration properties list file was moved to
+ "contrib/de.barton.ngircd.plist" and kept.
+ - Fix showing the "Ident" option in "--configtest" output which was never
+ shown because of a coding error. Whoops!
+ - Change GnuTLS "slot handling" messages to debug level: Those messages are
+ about an internal implementation detail, not relevant for an administrator
+ of ngIRCd.
+ - Enlarge buffer for log messages: For example, SSL/TLS certificate
+ information can easily get longer than 256 characters. So enlarge the log
+ buffer to 1 KB to avoid cutting off relevant information.
+ - Respect "SSLConnect" option for incoming connections and do not accept
+ incoming plain-text ("non SSL") server connections for servers configured
+ with "SSLConnect" enabled. This change prevents an authenticated
+ client-server being able to force the server-server to send its password
+ on a plain-text connection when SSL/TLS was intended.
+ - Always try to close a connection with errors immediately, but try hard
+ to avoid too much recursion. Without this patch, an outgoing server
+ connection could get stuck in an "endless" state trying to write out data
+ over and over again.
+ - Add "hopm.service" to "Wants" and "Before" dependencies in the sample
+ systemd unit file (Hopm is the successor of Bopm).
+ - Update Debian package configuration using current "dh_make", package
+ dependencies and build rules. And no longer build 3 different versions,
+ only build "ngircd" which now includes support for IDENT, PAM (disabled in
+ the ngircd.conf installed by the package), SSL (OpenSSL), ZLib and IPv6.
+ - Return ERR_NOTEXTTOSEND on empty PRIVMSG content, which matches the
+ behavior of other servers.
+ - Add a new option "Autojoin" to [Channel] blocks: When it is set, ngIRCd
+ automatically joins all local users to this channel on connect. Note: The
+ users must have permissions to access the channel, otherwise joining them
+ will fail!
+ Thanks Ivan Agarkov <i_agarkov@wargaming.net> for the initial patch!
+ - Hide invisible (+i) users on "WHOIS <pattern>": Let's behave like most(?)
+ other IRC daemons (at least ircd2.11) and hide all +i users when WHOIS is
+ used with a pattern. Otherwise privacy of this users is not guaranteed and
+ the +i mode a bit useless ...
+ Reported by Cahata on #ngircd, thanks!
+ - Update the final "closing connection" message: Add some more information
+ like nick name, user name, host name and bring it in line with some other
+ implementations (at least ircd2.11 and Hybrid).
+ - Fix RPL_INVITING message: All numeric replies must originate from an IRC
+ server, never from a client. Thanks "tommyrot" for reporting this!
+ Closes #307.
+ - Enhance some log messages, for example for errors when accepting new
+ connections.
+ - Make the debug log level ("--debug"/-"d" command line option) always
+ available, not only when ./configure'd with "--enable-debug": the latter
+ now only enables additional checks (like the tests done using assert(2))
+ and is signalled by adding "+DEBUG" to the version "feature string". This
+ change enables everyone to get even more detailed logging when required.
+ - Always report an error when a parameter is missing in a channel "MODE +k"
+ or "MODE +l" command, and better validate their parameters: return the new
+ numeric ERR_INVALIDMODEPARAM_MSG(696) on errors.
+ Thanks Val Lorentz for reporting this!
+ Closes #290.
+ - Allow IRC Operators to use the WHO command on any channel.
+ - Add configuration for "ngIRCd CI" GitHub Action, no longer use Travis-CI.
+ - Send the NAMES list and channel topic to users "forcefully" joined to a
+ channel using NJOIN, like they joined on their own using JOIN, and
+ streamline the order of NAMES list and channel topic messages.
+ Closes #288.
+ - Fix (invalid) error messages when setting modes on local channels which
+ are defined in the configuration file.
+ - Fix handling of G-Lines/K-Lines with cloaked host names.
+ - Streamline logging of debug messages.
+ - Added a new command line option "-y"/"--syslog", with which logging to
+ syslog can be activated/deactivated separately from running on the console
+ (using "--nodaemon") or in the background.
+ Thanks Katherine Peeters for the patch and pull request!
+ Closes #294.
+ - Fix a possible race condition while introducing new clients in the network.
+ - Update, enhance and extend our documentation in README.md, INSTALL.md,
+ doc/HowToRelease.txt and the manual pages ngircd(8) and ngircd.conf(5), add
+ a new doc/QuickStart.md document, and convert some more documentation files
+ to Markdown (AUTHORS.md, contrib/README.md, doc/FAQ.md, doc/SSL.md).
+
+ngIRCd 26.1 (2021-01-02)
+
+ - Fix a "format string" compiler warning (detected on OpenBSD).
+ - No longer set "AI_ADDRCONFIG" when resolving host names, even when it
+ exists: with this option set, on an IPv6-only host, we prevent 127.0.0.1
+ to get translated properly, even when the loopback interface has this
+ address configured! And as the test suite uses 127.0.0.1, it was broken
+ on IPv6-only hosts.
+ The drawback is that the resolver possibly returns more addresses now,
+ even of an unsupported/not connected address family; but this shouldn't
+ do much harm in practice, as ngIRCd iterates over all returned addresses
+ while trying to establish an outgoing connection.
+ Closes #281.
+ - Revert "Show allowed channel types in ISUPPORT(005) numeric only", which
+ was introduced in 26~rc1: This lead to some IRC clients assuming "oh, no
+ channel prefix characters at all, so no channels at all, so no PRIVMSG can
+ go to any channel" when "AllowedChannelTypes" was set to the empty string
+ ("") -- which is not the case when there are pre-defined channel set up or
+ other servers still having channels!
+ So "allowed channel types" != "supported channel types", and we always have
+ to list all supported ones in the ISUPPORT(005) numeric!
+ Closes #285.
+ - Test suite: Wait 2 seconds after reloading the daemon, which is required
+ because on reload, all listening ports are closed, configuration updated,
+ and then opened again. This lead to subsequent tests running while the
+ daemon isn't listening on any ports, and that's why some tests could fail.
+ Closes #280.
+ - platformtest.sh: Try to mangle CLang name more intelligently.
+ - Documentation: Fixed URLs of Atheme IRC services, updated all mentions
+ from CVS to Git, and updated Platforms.txt -- Oh, and it is 2021 now! ;-)
+
+ngIRCd 26 (2020-06-20)
+
+ ngIRCd 26~rc2 (2020-06-11)
+ - Add AppStream metadata file (contrib/de.barton.ngircd.metainfo.xml).
+ - Don't send invalid CHANINFO commands when a channel has mode +k set but no
+ key is known to the server. This can happen with a misconfigured predefined
+ channel, for example, and looked like this: "CHANINFO #test +Pk 0 :" --
+ note the unset key represented by the two spaces. Fix this by sending a
+ "*" in this case and update the CHANINFO documentation, too.
+ - ngircd.spec: Fix names of README.md and INSTALL.md, add ".md" extension.
+ - Update description texts in the README.md file, the RPM and Debian package
+ files and the manual page: bring them in line with the updated homepage.
+ - Server-Server protocol: Fix use-after-free when unregistering a directly
+ connected server sending a SQUIT for itself.
+ - Server-Server protocol: Detect bogus SERVER commands lacking a prefix.
+ Thanks Hilko Bengen (hillu) for finding & reporting this as well for the
+ patch & pull request (even if fixed differently).
+ Closes #275.
+ - Fix the PING-PONG logic: In ngIRCd 26~rc1 this was completely broken (while
+ trying to fix timeouts during server handshakes in bigger networks): the
+ daemon never disconnected any stale peers but kept sending out PINGs over
+ and over again ...
+ - Test suite: Add missing files needed to test SSL support to "EXTRA_DIST",
+ so that they are included in distribution archives: in rc1, "make check"
+ fails when using sources from an archive and enabling SSL support.
+ Thanks to Hilko Bengen <bengen@hilluzination.de> for the patch!

this/those command(s) to be handled first and don't try to read even more

- Update test suite to include SSL tests, including checking for reloading
certificates during runtime.
- Makefile.am: Replace "make" with "${MAKE}". This fixes warnings like this:
"error" before). Exit with code 2 ("command line error") for all other
invalid command line options, and show the error message itself on stderr
(instead of stdout and exit code 1, "generic error", as before).
