Remove legacy configuration options and related functions that have
been marked for removal for some time:
- PredefChannelsOnly (v22)
- NoticeAuth (v24)
- NoXXX (v19)
- Old '[GLOBAL]' section handling (v19)
This applies the same logic we have for write buffers to distinguish
between server and client connections and sets the maximum buffer size
accordingly. As a result peering with servers with many GLINE/KLINEs
does not kill the connecting server connection anymore.
Depending on the stack size, too many clients on the same channel
quitting at the same time would trigger a crash due to too many
recursive calls to Conn_Close().
This requires keeping track of currently active certificates, so those
are stored separately, along with a reference counter, and discarded
when they are no longer in use.
Fix the handling of legacy "Key" and "MaxUsers" [Channel] settings:
- Activate them before evaluating the "Modes" parameter, to allow the
latter to override those legacy options.
- Enforce setting the respective +k/+l mode(s) to support the legacy
"Mode = kl" notation, which was valid but is an invalid MODE string:
key and limit are missing! So set them manually when "k" or "l" are
detected in the first MODE parameter.
- Sort modes +kl alphabetically, adjust test suite accordingly.
Fix the following Clang "LeakSanitizer" error (which isn't quite
relevant in this test program, but anyway):
ERROR: LeakSanitizer: detected memory leaks

Systrace was removed from OpenBSD and NetBSD, so remove this (old and
outdated?) configuration file from the ./contrib directory.
See <https://en.wikipedia.org/wiki/Systrace>.
Thanks to "michi" for pointing this out on #ngircd!
Return with exit code 0 ("no error") when "--help" or "--version" was
used (this resulted in exit code 1, "error" before).
And exit with code 2 ("command line error") for all invalid command
line options, and show the error message on stderr (message was printed
to stdout before, and exit code was 1, "generic error").
This new behaviour is more in line with the GNU "coding standards",
see <https://www.gnu.org/prep/standards/html_node/_002d_002dhelp.html>.
This script parses the log output of ngircd(8), and colorizes the
messages accoring to their log level. Example usage:
ngircd -f $PWD/doc/sample-ngircd.conf -np | ./contrib/nglog.sh
Previously, each server would cloak every user's hostmask. The problem
is that if a network has more than one server, then a user's hostmask
would get cloaked twice. This patch ensures that a server only cloaks
the hostmask if it has not yet been cloaked (the period indicates it's
still an IP address).
Closes#228.
Without this, the configure script assumes and states that OpenSSL will
be used, but the code won't include support for it because there we use
the "HAVE_LIBSSL" define to test for it ("#ifdef HAVE_LIBSSL").
So define the latter when pkg-config(1) is used, too.
This fixes#257, a regression introduced by commit ad86a41ee :-/
This includes:
- "Real name" of a client (4th filed of the USER command).
- Server info text ("Info" configuration option).
- Admin info texts and email address ("AdminInfo1", "AdminInfo2" and
"AdminEmail" configuration options).
- Network name ("Network" configuration option).
The limit was 64 bytes before ...
Closes#258.
Don't exit during runtime (REHASH command, HUP signal), because the
server name can't be changed in this case anyway and the new invalid
name will be ignored.
- Show name of configuration file at the beginning of start up.
- Add a message when ngIRCd is ready, including its host name.
- Show name of configuration file on REHASH (SIGHUP), too.
- Change level of "done message" to NOTICE, like "starting" & "ready".
- Initialize IO functions before channels, connections, clients, ...
OpenSSL can depends on lz or latomic so use pkg-config to find those
dependencies and fallback to existing mechanism.

Closes#256.
The max length is actually 126 (< 127), since the check errors out if
length >= 127. See
<https://github.com/ngircd/ngircd/blob/master/src/ngircd/conf.c#L1487>.
I didn't look through the history to see when the change happened. I
just happened to find during a migration that my 140 character MOTD
didn't work.
Update sample configuration file as well as the man page.
This option configures the maximum penalty time increase in seconds, per
penalty event. Set to -1 for no limit (the default), 0 to disable
penalties altogether. ngIRCd doesn't use penalty increases higher than 2
seconds during normal operation, so values higher than 1 rarely make
sense.
Disabling (or reducing) penalties can greatly speed up "make check" runs
for example, see below, but are mostly a debugging feature and normally
not meant to be used on production systems!
Some example timings running "make check" from my macOS workstation:
- MaxPenaltyTime not set: 4:41,79s
- "MaxPenaltyTime = 1": 3:14,71s
- "MaxPenaltyTime = 0": 25,46s
Closes#249.
