This patch introduces the new function Conf_NickIsBlocked() which checks
if a given nick name matches with the "service mask" of a configured server.
And Client_CheckNick() uses this information to deny such names for regular
IRC users.
So nick names intended for IRC services are more protected and can't be used
by regular users even when the "services pseudo-server" isn't connected to
the network.
But please note:
Up to now, there can be only one "ServiceMask" pattern per server, which
most probably blocks much more nick names than really required ...
So "ServiceMask" should allow more than one pattern which can be more
specific, and most probably it should be possible to block nick names in
the global server configuration as well.
Nick names introduced by other servers/services are never restricted.
This patch implements the core functions to support "IRC Capabilities"
and the IRC "CAP" command as used by other servers and specified here:
<http://www.leeh.co.uk/draft-mitchell-irc-capabilities-02.html>.
It enables ngIRCd to support the defined handshake, but it doesn't
implement any capabilities, so "CAP LS" and "CAP LIST" always return
the empty set and "CAP REQ ..." always fails with "CAP NAK".
The numeric RPL_WHOISHOST_MSG(378) returns the DNS hostname (if
available) and the IP address of a client in the WHOIS reply.
Only the user itself and local IRC operators get this numeric.
This allows a channel operator to define exception masks that allow users
to join the channel even when a "ban" would match and prevent them from
joining: the exception list (e) overrides the ban list (b).
If the target user of a PRIVMSG or NOTICE command has the user mode 'C'
set, it is required that both sender and receiver are on the same channel.
This prevents private flooding by completely unknown clients.
- 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.
"I've been wanting this for years and finally took the 5 minutes to
patch it in. I took the response code (275) from whatever's running
OFTC's IRC network."

(OFTC is running Hybrid ircd.)
The RPL_STATSCONN numeric (250) displays information about the
highest simoultaneous connection count and the number of all
accepted connections since the daemon started up.
Used by ircd-Hybrid, Bahamut, and Unreal for example.
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.
The IRC command "SERVLIST" lists all the registered services, see RFC 2811, section 3.5.1.
The syntax is "SERVLIST [<mask> [<type>]]". The parameter <type> is not used by ngIRCd at
the moment, all registered services are of type 0 (which is the default when omitted).
It is hard to test this in the test suite because we 1) shouldn't rely on
previous tests populating WHOWAS and 2) don't connect a user for more than 30
seconds.
Also makes WHOWAS return ERR_NONICKNAMEGIVEN_MSG as implied by RFC.
SERVICE, SERVLIST, and SQUERY are required by RFC 2812 (it states in
section 3 that "all commands described in this section MUST be implemented
by any server for this protocol." -- So we implement them without (much)
actual functionality ...
Add support for modeless channels (+channels).
