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outdated?)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.
For example:
* src/ngircd/irc-login.c:102:21: Implicit conversion loses integer
precision: 'int' to 'char'
* src/ngircd/conn.c:1084:9: Implicit conversion turns floating-point
number into integer: 'double' to 'bool'
* src/tool/tool.c:85:10: Implicit conversion loses integer precision:
'int' to 'char'
According to an IRCv3 extension, the 5th parameter can be used for extra
flags that are fine to ignore for now, but limiting WEBIRC params to 4
causes a syntax error.
See https://github.com/ircv3/ircv3-ideas/issues/12 for more information.
This closes#247.
When ngIRCd failed to spawn a new resolver subprocess, the connection
structure was still marked as "SERVER_WAIT", and no new attempt to
connect to this server was made.
Thanks to Robert Obermeier for reporting this bug!
Closes#243.
This patch fixes a "use after free" bug which is hit while processing
ERROR commands while a new client is logging into the server, which
leads to only the CLIENT structure becoming freed, but not the
CONNECTION structure, too. And this leads to the daemon accessing the
already freed CLIENT structure later on ...
So now IRC_ERROR() uses the correct function Conn_Close() to correctly
free both structures.
The CONNECTION structure is cleaned up later on, and the freed CLIENT
structure can't be overwritten during normal operations, therefore this
bug normally can't crash (DoS) the service -- but you can easily hit it
when using the GCC option "-fsanitize=address", or run ngIRCd with
Valgrind.
Thanks a lot to Joseph Bisch <joseph.bisch@gmail.com> for discovering
and reporting this issue!
This prevents the channel from becoming flooded by unecessary TOPIC
update messages, that can happen when IRC services try to enforce a
certain topic but which is already set (at least on the local server),
for example. Therefore still forward it to all servers, but don't inform
local clients (still update setter and timestamp information, though!)
Update user mode "C" handling ("Only users that share a channel are
allowed to send messages") to behave like user mode "b" ("block private
messages and notices") and therefore allow messages from servers, services,
and IRC Operators, too.
Change proposed by "wowaname" in #ngircd, thanks!
