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.
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.
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).
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.
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.
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.
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".
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 ...
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.
These two functions return the cloaked hostname, if the client has
enabled hostname cloaking indicated by the -- still to implement --
user mode "x". See furter patches :-)
The Client_SetOrigUser() function is used to store the peer-provided
user name (see USER command) in its original form, not changed by
IDENT results, for example.
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.
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.
