Alexander Barton eccbd97e1f Remove CLIENT.oper_by_my, Client_SetOperByMe() and Client_OperByMe()
All places where Client_OperByMe() is used can either be converted to
Client_HasMode(Client, 'o') or Op_Check().

And Op_Check() itself can use the connection handle for deciding whether
the IRC Operator is a local user or not.

Federico G. Schwindt 9f74c0ff07 Minor cosmetic change
Add a define to indicate any client.  While I'm here use hex values
instead of decimal, it's somewhat clearer that they could be OR'ed
together.

Alexander Barton 1dc93286a0 Save client IP address text for "WebIRC" users
This patch introduces a new field in the CLIENT structure, "ipa_text",
which points to an optional textual representation of the client IP
address (or NULL) which can be used to store the "real" IP address
information of a client using the "WEBIRC" protocol.

Without this patch, ngIRCd ignored the <ip-address> paramater ...

In addition, the functions Client_SetIPAText() and Client_IPAText()
have been introduced to set and get the textual representation of the
client IP address.

Client_IPAText() can be used even when no "IP address text" has been
set before, it then returns the real IP address of the connection.

Closes bug #159.

Federico G. Schwindt 3af0ece2bc Implement account login support
This is done via the `accountname' METADATA command and used to
automatically identify users after netsplits or across service
restarts.

Federico G. Schwindt bb8d207efa Change cloaked hostname to be malloc'd on demand
This shaves a few bytes when cloaked hostnames are not used and
restricts the cloakhost announcement iif there is something to
send.

Federico G. Schwindt e03d8eb728 Add Client_HasFlag() to check if a client has certain flag 2013-08-04 04:00:34 +01:00
Federico G. Schwindt 8e60fac73b Improved client announcement
Move Announce_User() to client.c and rename it to Client_Announce().
Use this in cb_introduceClient() instead of duplicating the code.
This fix the certificate fingerprint announcement for new clients.
Also ensure the certificate fingerprint is only announced if the
client supports it (`M' flag).

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 35e2dcff88 Rework cloaked hostname handling, implement "METADATA cloakhost"
Now ngIRCd uses two fields internally, one to store the "real" hostname
and one to save the "cloaked" hostname. And both fields can be set
independently using the "METADATA host" and "METADATA cloakhost" commands.

This allows "foreign servers" (aka "IRC services") to alter the real and
cloaked hostnames of clients without problems, even when the user itself
issues additional "MODE +x" and "MODE -x" commands.

Brett Smith 0d5de60584 Move client password from the Client to the Connection struct.
This is a relatively naive implementation, basically doing the bare minimum
necessary to make the switchover go.  Subsequent commits can focus on
improving the implementation.

Alexander Barton bd3a7ccb15 Implement core IRC capability handling and "CAP" command
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".

Alexander Barton 162433398e New configuration option "RequireAuthPing": PING-PONG on login
When enabled, this configuration option lets ngIRCd send a PING with an
numeric "token" to clients logging in; and it will not become registered
in the network until the client responds with the correct PONG.

This is used by QuakeNet for example (ircu/snircd), and looks like this:

  NICK nick
  :irc.example.net PING :1858979527
  USER user . . :real name
  PONG 1858979527
  :irc.example.net 001 nick :Welcome to the Internet Relay Network ...

Alexander Barton 355828e64f Enable the daemon to dump its internal state in debug-mode.
This patch allows ngIRCd to dump its internal state (connected clients,
actual configuration) when compiled with --enable-debug. The daemon
catches two more signals:

 - SIGUSR1: toggle debug mode (on/off),
 - SIGUSR2: dump internal state to console/syslog.

Alexander Barton 1995af0ed6 New functions Client_[Set]OrigUser() to get/set user specified by peer

IDENT results, for example.

Alexander Barton 33f32dbd67 New function Client_TypeText() and Destroy_UserOrService().
Client_TypeText() is used to get correct naming ("Client", "Service", ...)
for log messages, and Destroy_UserOrService() is used to correctly destroy
user and services clients.

Alexander Barton a60465be3e Server links: detect RFC 1459 mode direct after SERVER command
This patch allows ngIRCd to detect right after receiving the SERVER command
from the peer whether the RFC 1459 compatibility mode must be used or not.
And it fixes the announcement of users during establishing new server links
with such peers.
