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]
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.
This should fix the following compiler warning:
resolve.c:113:1: warning: ‘Get_Error’ defined but not used
[-Wunused-function]
Which can happen, because the logic of commit 543f44bf isn't sufficient:
Get_Error() is only used when neither HAVE_WORKING_GETADDRINFO nor
HAVE_GETNAMEINFO are set ...
Enhances 543f44bf.
Closes#241.
In the end, service clients behave like regular users, therefore IRC
operators and servers should be able to KILL them: for example to
resolve nick collisions.
This is related to #238.
The usage of Get_Error is guarded by "ifdef h_errno" in this file, the
definition of this function should follow the same rules.

The daemon only enlarged its connection pool when accepting new client
connections, not when establishing new outgoing server links.
Thanks to Lukas Braun (k00mi) for reporting this!
In addition this patch streamlines the connection pool allocation, so
that there is only one place in the code allocating the pool: the now
updated Socket2Index() function. The name doesn't quite fit, but this
existing and today quite useless function (because the mapping from
socket number to connection index is 1:1 today) already became called
in almost all relevant code paths, so I decided to reuse it to keep the
patch small ...probably we want to fix the naming in a second patch?
Closes#231.
- Add more comments/documentation.
- Add dependencies for services and proxy scanners.
- Add more limit configurations.
- Allow AF_UNIX address family, required for syslog!
- Add homepage :-)
- Remote CAP_SETUID and CAP_SETGID from CapabilityBoundingSet: This is
nor needed, because the unit already sets User=irc and Group=irc.
- Add RestrictAddressFamilies, and restrict it to AF_INET and AF_INET6.
- Read in the Debian "default files", but note: only PARAMS is supported!
- Update debhelper compatibility to version 9.
- Update build-dependencies.
- Change group of ngircd.conf to "irc" in postinst script (this makes
starting ngIRCd as user "irc" easier, for example when using systemd).
- Don't create /var/run/ircd during installation: this is handled by the
SysV init script and the systemd service already.
Don't wait for the peer to close the connection. This allows us to
forward the ERROR mesage in the network, instead of the very generic
"client closed connection" message.
Explicitely forbid remote servers to modify "x-lines" (G-LINES) when the
"AllowRemoteOper" configuration option isn't set, even when the command
seems to originate from the remote server itself: this prevents GLINE's
to become set during server handshake in this case (what wouldn't be
possible during regular runtime when a remote IRC Op sends the command)
and what can't be undone by IRC Ops later on (because of the missing
"AllowRemoteOper" option) ...
At the moment, ngIRCd fails to build against OpenSSL 1.1 since the
configure check probes for the SSL_library_init symbol which was
removed, but probing for a different function availabe in both versions
solves that problem: SSL_new().
And as SSL_library_init is no longer needed, the patch boils down to
probing SSL_new to assert libssl is available, and disabling the
SSL_library_init invokation from OpenSSL 1.1 on, see also another
application[1] (NSCA-ng) that did pretty much the same.
Patch was compile-tested on both Debian jessie (OpenSSL 1.0.2) and
stretch (OpenSSL 1.1).
