The "Info" option in the "[Global]" section is optional (so comment it
out in the sample configuration file) and set to the server software
name and its version when not set (so add this information to the sample
configuration file and the ngircd.conf(5) manual page).
|
|
The server "Name" in the "[Global]" section of the configuration file is
optional now: 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 behaviour, with all configuration parameters now being
optional, allows running ngIRCd without any configuration file at all.

Basically this is unnecessary, as Channel_UserModes() always returns a
valid pointer and strchr() can deal with an empty (NULL-terminated)
string perfectly fine, bit it makes the code a bit more obvious and
silences the following warning:
In function ‘Channel_UserHasMode’,
inlined from ‘Channel_Kick’ at channel.c:384:7:
channel.c:784:16: warning: ‘strchr’ reading 1 or more bytes from a region
of size 0 [-Wstringop-overread]
784 | return strchr(Channel_UserModes(Chan, Client), Mode) != NULL;
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This was seen with "gcc (Debian 12.2.0-14) 12.2.0" at least.

- Rewrite using current dh_make.
- Standards-Version: 4.6.2.
- No longer build 3 different packages; only build "ngircd" which now
includes support for IDENT, PAM (disabled in the ngircd.conf installed
by the package), SSL (OpenSSL), ZLib and IPv6.
- Update package description accordingly.
- No longer install a SysV init file, only install ngircd.service unit.
|
|
This affects targets for Apple Xcode and Package Maker, which both are
no longer supported/included in the ngIRCd distribution.
See commits 0652c99b and 07219281, this is a leftover ...

Clang does not know the -Wno-format-truncation option of (current) GCC,
but accepts unknown -W... options (exit core 0) but issues a warning
message on every invocation. So for example on macOS, where Clang is
used as "gcc", a new warning message was shown for every file to
compile, since we enabled -Wno-format-truncation in commit 1d527eaf:
warning: unknown warning option '-Wno-format-truncation' [-Wunknown-warning-option]
Clang no longer acceps unknown -W... options by enabling -Werror, which
this patch adds to the CFLAGS while testing for -Wno-format-truncation,
which fixes this issue.
This fixes commit 1d527eaf.

Add a "/* fall through */" annotation to "case" statements which
actually should "fall through" to silences GCC warning like this:
hash.c: In function ‘jenkins_hash’:
hash.c:110:27: warning: this statement may fall through
[-Wimplicit-fallthrough=]
110 | case 12: c+=((UINT32)k[11])<<24;
| ~^~~~~~~~~~~~~~~~~~~~~
|
|
Pass -Wno-format-truncation when this is supported by GCC so silence
warnings like this:
conf.c: In function ‘Read_Config’:
conf.c:985:60: warning: ‘snprintf’ output may be truncated before
the last format character [-Wformat-truncation=]
985 | snprintf(file, sizeof(file), "%s/%s",
| ^
conf.c:985:25: note: ‘snprintf’ output 2 or more bytes (assuming 257)
into a destination of size 256
985 | snprintf(file, sizeof(file), "%s/%s",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
986 | Conf_IncludeDir, entry->d_name);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The warning is correct, but this is basically why we use snprintf() in
the first place.

GNU automake 1.11 is the last release supporting "de-ANSI-fication"
using the included ansi2knr tool. And becuase we _want_ to support old
K&R platforms, we try hard to use this release of automake when
available to generate our build system.
|
|
Until now, IPv6 support was disabled by default, which seems a bit
outdated in 2024. Note: You still can pass "--enable-ipv6" or
"--disable-ipv6" to the ./configure script to forcefully activate or
deactivate IPv6 support.
|
|
Without this patch, disabling DNS in the configuration disabled IDENT
lookups as well (for no good reason).
This patch allows enabling/disabling DNS lookups and IDENT requests
completely separately and enhances the messages sent to the client when
"NoticeBeforeRegistration" is enabled, too.
Thanks for reporting this, Miniontoby!
Closes #291.

This was reported back in April 2021, thanks Sarah!
Subject: NGIRCD bug report
Date: April 28 2021, 14:30:08 MESZ
To: alex@barton.de
Hello,
I am writing to you to report a bug in ngircd.
In any give channel, if an user is with mode +a (admin), he/she can
sets mode +/-q(owner) to any other user. This is not inline with the
documentation.
I've looked into the code irc-mode.c, apparently an if block is
missing. Below are the code snippets that I believe fixes the bug.
This patch is what Sarah sent in. Thanks a lot!

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
you fully trusted network, where SSL is not required.
|
|
This includes removing the Xcode project.
The sample launchd(8) configuration properties list file was moved to
"contrib/de.barton.ngircd.plist" and kept.
|
|
|
|
|
|
|
|
We tested for the wrong #define ... ooops!
|
|
Those messages are about an internal implementation detail, not relevant
for an administrator of ngIRCd.
|
|
For example, SSL/TLS certificate information can easily get longer than
256 characters. So enlarge the log buffer to 1 KB.
|
|
Don't accept incoming plain-text ("non SSL") server connections for
servers configured with "SSLConnect" enabled.
If "SSLConnect" is not set for an incoming connection the server still
accepts both plain-text and encrypted connections.
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.
This tries to fix 04de1423eb26.

This not only bumps the "compat" version, but updates the package
dependencies and build rules accordingly.
Closes #299.

They are dropped further down the line anyway; and sending ERR_NOTEXTTOSEND
early matches other servers' behavior.

Thanks Katherine Peeters for the patch and pull request!
Closes #294.

Use strdup() instead of pointless strndup() to fix the following
compiler warning:
client.c: In function ‘Init_New_Client’:
client.c:216:32: warning: ‘strndup’ specified bound 127 exceeds source size 5 [-Wstringop-overread]
216 | client->away = strndup(DEFAULT_AWAY_MSG, CLIENT_AWAY_LEN - 1);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- Bring sample-ngircd.conf and ngircd.conf.5 description in line.
- Fix configuration parsing, it always showed the 'Unknown variable
"Autojoin"' error message, even when everything was perfectly fine.
- And fix a build error (at least on macOS with Apple Clang 14):
login.c:234:3: error: call to undeclared function 'IRC_JOIN'; ISO
C99 and later do not support implicit function declarations
[-Wimplicit-function-declaration]
IRC_JOIN(Client, &Req);
^
The #include for the "irc.channel.h" header was missing!
- Remove a unused variable that caused a compiler warning:
login.c:222:12: warning: unused variable 'n' [-Wunused-variable]
size_t i, n, channel_count = array_length(&Conf_Channels, sizeof(*conf_chan));
^
- Add a explicit cast to fix a compiler warning:
login.c:235:15: warning: assigning to 'char *' from 'const char[51]'
discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
Req.argv[0] = conf_chan->name;
^ ~~~~~~~~~~~~~~~

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!
|
|
Add some more information (nick name, user name, host name) and bring it
in line with some other implementations (at least ircd2.11 and Hybrid).
|
|
All numeric replies must originate from an IRC server, never from a
client. So fix the RPL_INVITING message!
Thanks tommyrot for reporting this!
Closes #307.
|
|
|
|
Otherwise, the probe always fails with compilers which do not
support implicit function declarations.
|
|
The debug log messages are always available and a runtime option (since
commit c7de505c), but the assert()'s are only active when ngIRCd was
configured with the "--enable-debug" option.
So only add "+DEBUG" to the version string when the latter is the case.
|
|
This basically means to unifdef DEBUG in (almost) all places.
We keep it in src/portab/portab.h so DEBUG stays available to
enable assert(). Also add a comment about this.
|
|
Implement new numeric ERR_INVALIDMODEPARAM_MSG(696) and:
- Reject channel keys with spaces and return ERR_INVALIDMODEPARAM_MSG;
This was possible until now and resulted in garbled IRC commands later.
- Reject empty channel keys and return ERR_INVALIDMODEPARAM_MSG;
This was possible until now and resulted in garbled IRC commands later.
- Return ERR_INVALIDMODEPARAM_MSG when user limit is out of bounds;
This was silently ignored until now.
Closes #290. Thanks Val Lorentz for reporting it!
