Initialize listening socket: Streamline error message

Correctly retry outgoing conenctions when forking a resolver failed

2018-03-25T19:59:01+00:00

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.

Fix use-after-free while handling ERROR during client login

2018-03-11T20:18:38+00:00

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 for discovering and reporting this issue!

Only send TOPIC updates to a channel when the topic actually changed

2018-03-11T20:01:45+00:00

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!)

User mode "C": Allow messages from servers, services, and IRC Ops

2018-02-25T02:22:05+00:00

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!

Fix compiler warning in ForwardLookup()

2018-01-29T22:34:40+00:00

When compiling without "working getaddrinfo()", the "af" parameter of ForwardLookup() is unused by that function. Mark it as such! This prevents the following compiler warning: resolve.c:235:56: warning: unused parameter ‘af’ [-Wunused-parameter]

Fix compiler warning in Option_String()

2018-01-29T22:32:06+00:00

When compiling ngIRCd without support for SSL and without support for ZLIB, gcc outputs the following warning: irc.c:493:9: warning: variable ‘options’ set but not used [-Wunused-but-set-variable] Fix it by providing a dummy function in this case.
