Alexander Barton 7ea3864a93 IncludeDir: default to "$SYSCONFDIR/ngircd.conf.d"
Now "IncludeDir" defaults to "$SYSCONFDIR/ngircd.conf.d" instead
of no directory, but a missing directory is only reported as an
error if it has explicitely configured in the main configuration
file and simply ignored otherwise.

Therefore it is now possible not to touch the default (sample)
configuration file at all, and set all distribution and/or system
specific configuration options in "*.conf" files stored in
"$SYSCONFDIF/ngircd.conf.d/".

Thanks to "Elmasloco" for the idea!

Alexander Barton 891dbd2acc "IncludeDir" can't be overwritten by included files 2013-05-24 22:40:23 +02:00
Alexander Barton f206fda8ae Implement new configuration option "IncludeDir"
The option "IncludeDir" in the [Options] section can be used
to specify a directory which can contain further configuration
files and configuration file snippets matching the pattern
"*.conf" that should be read in after the main configuration
file ("ngircd.conf" by default) has been parsed.

Closes bug #157.

Alexander Barton 27fd92d580 Rename "Mask" variables into "Pattern" in assert() statements

Federico G. Schwindt 51e5ba94b3 Ensure there is enough space for the mask
As pointed by Alex while strl{cat,cpy} take the full length
we need to leave space to ensure a proper mask is always created
so revert the removal of - N from my last change.

Federico G. Schwindt b4d0a40383 Better description for Lists_CheckReason() 2013-04-20 00:44:05 +01:00
Federico G. Schwindt 3ab00e3a11 Change Lists_MakeMask() to receive a buffer for the mask
Change callers accordingly so they don't rely on a global buffer and
rename Mask to Pattern where it makes sense since some functions
where indeed receiving a pattern and not a mask.

Federico G. Schwindt cde2e8a277 Fix use-after-free on Lists_CheckReason()
Change Lists_CheckReason() to receive a buffer where the reason
will be stored and its length.  Change callers accordingly.

Change Class_GetMemberReason() (and its callers) in a similar way
so it doesn't rely on a global buffer for the rejected reason.

Alexander Barton a2e26aad1e Conn_Handler(): Don't test for penalty times
The Conn_Handler() main loop calls Handle_Buffer() which checks for the
"penalty time" of each client itself, so don't do it twice.

Alexander Barton b4393277ea Don't read SSL client data before DNS resolver is finished
Fix the cb_clientserver_ssl() callback function to not read in and store SSL
encrypted client data before the asynchronous DNS resolver sub-process has
finished: This could have resulted in discarding the resolved client hostname
and IDENT reply afterwards, because in some situations (timing dependent) the
NICK and USER commands could have already been read in from the client,
stored in the buffer, and been processed.

Thanks to Julian Brost for reporting the issue and testing, and to Federico
G. Schwindt <fgsch@lodoss.net> for helping to debug it!

* bug155-allowAtInUser:
  Allow "@" character in user names for authentication
2013-02-11 13:58:30 +01:00
Alexander Barton 4b15f10fbb Allow "@" character in user names for authentication
The "@" character isn't allowed in IRC usernames, because it is the
separator between user name and hostname in IRC masks:

  <nickname>!<username>@<hostname>

This patch accepts user names including "@" characters, saves the
unmodified name for authentication but stores only the part in front
of the "@" character as "IRC user name". And the latter is how
ircd2.11, Bahamut, and irc-seven behave as well.

Closes bug #155.

Alexander Barton 5dce3301bd Update irc-info.c to use irc-macros.h
This includes:

 - move IRC_SetPenalty() at the beginning of the handler functions,
 - use macros provided by irc-macros.h,
 - code cleanup.

The main benefits of this patch are core size reduction, streamlined
structure of the handler functions, and enhanced functionality:
because of the _IRC_GET_TARGET_SERVER_OR_RETURN_() macro using the
Client_SearchServer() function, the target of the specific IRC command
can now be given server names, server mask, or the nickname of a user
connected to the server.

Closes bug #153.

Alexander Barton 1e8b775a7a "WHO <hostmask>": use displayed hostname for matching
Use the currently "displayed hostname" (which can be cloaked!) for
hostname matching, not the real one. In other words: don't display
all the cloaked users on a specific real hostname!

Thanks to DNS <dns@rbose.org> for reporting this issue.

Alexander Barton 0ad0fe207a Implement new function Client_SearchServer()
This function returns the server structure of a client or a given "mask";
it is useful for implemention handlers for commands like "COMMAND *.net",
which should work on a server matching "*.net".

Please note that the local server is always returned when it matches the
mask, but besides that, the order is completely arbitrary.

Alexander Barton f295117fba New configuration option "IdleTimeout": exit daemon when idle
This patch implements a new configuration option "IdleTimeout" in the
[Limits] section of the configuration file which can be used to set a
timeout (in seconds) after which the whole daemon will shutdown when no
more connections are left active after handling at least one client.

The default is 0, "never".

This can be useful for testing or when ngIRCd is started using "socket
activation" with systemd(8), for example.
2013-02-04 23:15:53 +01:00
Alexander Barton 8ab097afb7 Implement support for systemd(8) "socket activation"
This patch enables ngIRCd to work with listening sockets already
initialized and passed-in by systemd(8) and hereby to support on-demand
"socket activation".

systemd(8) uses two environment variables to pass information about the
sockets to ngIRCd, LISTEN_PID and LISTEN_FDS, and this mechanism only
kicks in when both variables are set. In all other cases, and therefore
in most installations out there, nothing changes at all.

Please note:
If socket activation is in effect, ngIRCd will not initialize any (other)
soeckets on its own! All sockets must be configured in the systemd(8)
socket unit configuration file in this case, see ./contrib/ngircd.socket
for example.

Probably it would be interesting to match passed-in sockets to configured
listening sockets and to initialize all the remaining ones not already
set up by systemd(8), but this is kept back for an other patch ...

Alexander Barton 84a599ece4 Enable WHOIS to display information about IRC Services
This patch introduces the new numeric 310(RPL_WHOISSERVICE) and enables
WHOIS to display information about IRC services. This numeric is used
for this purpose by InspIRCd, for example -- but as usual, other numerics
are in use, too, like 613 in UltimateIRCd ...

Please note that neither the Operator (+o) not the "bot status" (+B)
of an IRC service id displayed in the output.

Change suggested by Federico G. Schwindt <fgsch@lodoss.net>, Thanks.

Alexander Barton d38d153f51 Streamline punctuation of log messages
Make sure that all log messages end with a correct punctuation mark.

The rules for formatting log messages are:

 1. Add punctuation marks to all messages passed to the actual logging
    functions like Log() and LogDebug().
 2. Don't add any punctuation marks to messages that are stored in
    variables for later use or are passed over the network.
 3. IP addresses, DNS host names and IRC server names should be quoted.
 4. Messages originating in the network should be quoted (at least if
    they are "untrusted" or variable).

Most probably this patch doesn't fix all mistakes, but it should be a
good starting point ...
