This patch - introduces a new server flag "S" to indicate that the server can handle the SERVICE command (on server links), - implements the IRC command "SERVICE" for server-server links, - uses the "SERVICE" command to announce IRC services when a new server connects to it, - and fixes the Send_Message() function to let it send messages to services using a "target mask". If the remote server doesn't indicate that it can handle the "SERVICE" command (it has not set the "S" flag), services are announced as regular users as before.

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.

Introduce a new configuration variable "ServiceMask" in SERVER blocks to define a mask matching nick names that should be treated as services. Regular servers don't need this parameter (leave it empty, the default), but you should set it to "*Serv" when connection ircservices, for example. This patch allows ngIRCd to detect services, it doesn't change the functionality: you only get different log messages ;-)

All the required information is already stored in the CLIENT structure of new new connection, so pass this to Introduce_Client() and don't invent an unneeded new structure ...

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.

This patch enables ngIRCd to deal with NICK and USER commands following RFC 1459 to register new clients, and to send these commands instead of one full NICK command as specified in RFC 2813 on connections that are in RFC 1459 compatibility mode. Can be useful for e. g. IRC services that simulate a RFC 1459 server.

This new connection option CONN_RFC1459 indicates that the peer on this link only supports the IRC protocol as defined in RFC 1459 and that the compatibility mode (e. g. for outgoing commands like NICK) should be used.

This is required to do RFC 1459 style user registration on server links, and is used by some services packages, too. See RFC 1459 section 4.1.3.

This patch allows servers and services to call the NICK command using the syntax defined in RFC 1459 to register new users, with only two parameters. See section 4.1.2. Useful for some services packages, which emulate this protocol.

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 ...

(cherry picked from commit b187fac244f4e14705f882ba7c43eef0238e2830)

Hello_User() used strncpy with overlapping src/dest. Use memmove instead.

- New configuration option "MaxNickLength" to specify the allowed maximum length of user nick names. Note: must be unique in an IRC network! - Enhanced the IRC+ protocol to support an enhanced "server handshake" and enable server to recognice numeric 005 (ISUPPORT) and 376 (ENDOFMOTD). See doc/Protocol.txt for details.
