Alexander Barton a4d1e6007f IRC_LIST(): Code cleanup 2012-01-06 19:54:23 +01:00
Alexander Barton 565523cbb4 Don't stop join handling on faulty channel, skip it
When JOIN is received with more than one channel name, don't stop
processing on the first error (e.g. bad name, wrong channel key, ...)
but report an error and continue with the other given channel names.

Reported by Cahata -- thanks!

Alexander Barton 8aac366802 Implemented user mode "R" and channel mode "R"
- User mode "R": indicates that the nick name of this user is "registered".
   This mode isn't handled by ngIRCd itself, but must be set and unset by
   IRC services like Anope.

 - Channel mode "R": only registered users (having the user mode "R" set)
   are allowed to join this channel.

Alexander Barton 5ed7a4ea57 TOPIC command: test for channel admin rights correctly
This enables other servers, services and IRC operators to change
channel topics, even when the client is not joined to this channel.

Now the handler for TOPIC behaves like the one for MODE.

Alexander Barton 5462c6c50f Don't #include client.h when conn.h/conn-func.h is already included
conn.h and cinn-func.h both already #include client.h, so it is
not needed to do it twice.

Alexander Barton 9f58418765 Implemented new "secure clients only" channel mode: +z
Only clients using a SSL encrypted connection to the server are
allowed to join such a channel.

But please note three things:

a) already joined clients are not checked when setting this mode,
b) IRC operators are always allowed to join every channel, and
c) remote clients using a server not supporting this mode are not
   checked either and therefore always allowed to join.

Florian Westphal e9e7fc33f1 add and use Channel_IsModeless()
avoid "name[0] == '+'" where possible, having Channel_IsModeless()
makes things much more obvious.

Alexander Barton c5000694d1 Support individual channel keys for pre-defined channels.
This patch introduces the new configuration variable "KeyFile" for
[Channel] sections in ngircd.conf. Here a file can be configured for each
pre-defined channel which contains individual channel keys for different
users. This file is line-based and must have the following syntax:

  <user>:<nick>:<key>

<user> and <nick> can contain the wildcard character "*".

Please not that these channel keys are only in effect, when the channel
has a regular key set using channel mode "k"!

Alexander Barton 2cc21caf32 Implement local channels (prefix "&")
This patch implements server-local channels, prefix "&", that are only
visible to users of the same local server and not in the network.

Alexander Barton ec0b405d9d Respect RFC 1459 compatibility mode when announcing channels (no NJOIN). 2008-09-23 11:53:16 +02:00
Alexander Barton d93030ad27 Make real use of the CLIENT_SERVICE client type.
This patch enables ngIRCd to handle IRC services as real services, and not
as "fake users":

  - Set correct client type CLIENT_SERVICE for services,
  - Change log messages to include correct client type,
  - PRIVMSG: allow users to send messages to services,
  - Send services nick names to other servers (as users).

Please note that this patch doesn't announce services as services in the
network, but as regular users (as before). Only the local server knows
of services as services (see LUSERS command, for example). It is up to
one of the next patches to fix this and to introduce the SERVICE command
in server to server communication.

The propagation of services as regular users between servers doesn't limit
the functionality of the IRC services and will be the fallback for servers
that don't support "real" services propagation in the future.

Alexander Barton 258143897c Return 461 (syntax error) on "JOIN :" and "PART :"
Up to this patch ngIRCd did not return any result (GIT master) or a badly
formated 403 (":irc.server 403 test  :No such channel" [note the two
spaces!], branch-0-12-x) on the above commands, this patch changes the
behaviour to reflect ircd 2.11 which returns 461 in both cases.

Alexander Barton 258e39e89f Fix GCC warnings for possibly uninitialized variables in IRC_JOIN
This patch fixes the following two warnings of GCC 4.2.4:

irc-channel.c: In function "IRC_JOIN":
irc-channel.c:185:
 warning: "lastkey" may be used uninitialized in this function
irc-channel.c:185:
 warning: "lastchan" may be used uninitialized in this function

Scott Perry b90f71ca2a Use strtok_r instead of strchr in IRC_JOIN.
This patch does significant cleanup on the join code by using strtok_r
instead of mangling strchr to parse channel names and keys in parallel when
a JOIN command contains a list of channels and keys.

Also adds an strtok_r implementation to libportab.

Florian Westphal f7c2e8223f Always enable modeless channels.
Modeless channels (+channels) are described in RFC 2811;
so my modifications to
530112b114
('Add support for modeless channels')
to disable +channels for --strict-rfc configurations
were wrong. This reverts those changes.

 - don't support +channels when compiled with --strict-rfc
 - do not set +o mode for channel creator
 - force +nt mode when channel is created ]

Rolf Eike Beer 44cdf1b1ca Fix sending of JOINs between servers.
This does hit only operators that join a channel with at least 2 servers active in the net
the server the oper connects to sends "channel^Go" to the other servers
the other server first searches for the channel and then strips the modes from the channel name
he has to do the other way round: first strip and then check the channel name.

Florian Westphal 634ef8c131 IRC_JOIN cleanups.
- put sending of mode and forwarding of JOIN to other clients
 into seperate function.
- put sending of topic/channel names into seperate function.
- put access check into seperate function.
- translate/remove remaining german comments.
- stop if JOIN to a channel in a list (JOIN #a,#,b,#c...) fails
(This doesn't change the behaviour: skip-to-next-channel-on-error
did never work as intended)

Dana Dahlstrom 6bd35bf090 Implement RFC 2812 handling of "0" argument to JOIN
The students in my software-engineering class are writing IRC clients in
Java, and I'm running ngIRCd as a sandbox for them to play in. We
noticed ngIRCd doesn't obey the "JOIN 0" command specified in RFC 2812:

   JOIN 0             ; Leave all currently joined
                      channels.

http://tools.ietf.org/html/rfc2812#section-3.2.1
I believe the following patch addresses this. Cheers!

[fw@strlen.de: put it into a seperate function]
