Alexander Barton : Generate "METADATA host" commands on "MODE +/-x"

Module: ngircd.git Branch: master Commit: 40e3daf560799df1d16629b35078979583cb4349 URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=40e3daf5… Author: Alexander Barton <alex(a)barton.de> Date: Mon Nov 5 23:49:12 2012 +0100 Generate "METADATA host" commands on "MODE +/-x" Use "METADATA host" commands to let servers supporting this command know which (possibly cloaked) hostname is in effect for a specific client. This prevents "double cloaking" of hostnames and even cloaked hostnames are in sync on all servers supporting "METADATA" now. --- src/ngircd/irc-mode.c | 27 ++++++++++++++++++++++++--- 1 file changed, 24 insertions(+), 3 deletions(-) diff --git a/src/ngircd/irc-mode.c b/src/ngircd/irc-mode.c index ce4044d..1cf19af 100644 --- a/src/ngircd/irc-mode.c +++ b/src/ngircd/irc-mode.c @@ -36,6 +36,8 @@ #include "irc-mode.h" +static void Announce_Client_Hostname PARAMS((CLIENT *Origin, CLIENT *Client)); + static bool Client_Mode PARAMS((CLIENT *Client, REQUEST *Req, CLIENT *Origin, CLIENT *Target)); static bool Channel_Mode PARAMS((CLIENT *Client, REQUEST *Req, CLIENT *Origin, @@ -367,9 +369,7 @@ Client_Mode( CLIENT *Client, REQUEST *Req, CLIENT *Origin, CLIENT *Target ) Client_ID(Target), the_modes); if (send_RPL_HOSTHIDDEN_MSG) - IRC_WriteStrClient(Client, RPL_HOSTHIDDEN_MSG, - Client_ID(Client), - Client_HostnameCloaked(Client)); + Announce_Client_Hostname(Origin, Client); } LogDebug("%s \"%s\": Mode change, now \"%s\".", Client_TypeText(Target), Client_Mask(Target), @@ -381,6 +381,27 @@ Client_Mode( CLIENT *Client, REQUEST *Req, CLIENT *Origin, CLIENT *Target ) } /* Client_Mode */ +/** + * Announce changed client hostname in the network. + * + * @param Client The client of which the hostname changed. + */ +static void +Announce_Client_Hostname(CLIENT *Origin, CLIENT *Client) +{ + assert(Client != NULL); + + /* Inform the client itself */ + IRC_WriteStrClient(Client, RPL_HOSTHIDDEN_MSG, Client_ID(Client), + Client_HostnameCloaked(Client)); + + /* Inform other servers in the network */ + IRC_WriteStrServersPrefixFlag(Origin, Client_ThisServer(), 'M', + "METADATA %s host :%s", Client_ID(Client), + Client_HostnameCloaked(Client)); +} + + static bool Channel_Mode_Answer_Request(CLIENT *Origin, CHANNEL *Channel) {

Alexander Barton : Implement SVSNICK command to change remote nicknames

Module: ngircd.git Branch: master Commit: e3f300d3231f56efe2831fb79f7b484d96d051f5 URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=e3f300d3… Author: Alexander Barton <alex(a)barton.de> Date: Fri Nov 2 17:50:31 2012 +0100 Implement SVSNICK command to change remote nicknames The SVSNICK command allows other servers (and services on "pseudo-servers") to forcefully change nicknames of remote users. Syntax: ":<from> SVSNICK <oldnick> <newnick>" The SVSNICK command itself doesn't change the nickname, but it becomes forwarded to the server to which the user is connected to. And then this server initiates the real nickname changing using regular NICK commands. This allows to still run networks with old servers not supporting the SVSNICK command, because SVSNICK commands for nicknames on such servers are silently ignored and don't cause a desync of the network. --- src/ngircd/irc-login.c | 72 ++++++++++++++++++++++++++++++++++++++++-------- src/ngircd/irc-login.h | 3 +- src/ngircd/parse.c | 1 + 3 files changed, 64 insertions(+), 12 deletions(-) diff --git a/src/ngircd/irc-login.c b/src/ngircd/irc-login.c index c3f32b7..977fc54 100644 --- a/src/ngircd/irc-login.c +++ b/src/ngircd/irc-login.c @@ -1,6 +1,6 @@ /* * ngIRCd -- The Next Generation IRC Daemon - * Copyright (c)2001-2011 Alexander Barton (alex(a)barton.de) and Contributors. + * Copyright (c)2001-2012 Alexander Barton (alex(a)barton.de) and Contributors. * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by @@ -39,8 +39,8 @@ #include "irc-login.h" static void Kill_Nick PARAMS((char *Nick, char *Reason)); -static void Change_Nick PARAMS((CLIENT * Origin, CLIENT * Target, - char *NewNick, bool RegisterWhowas)); +static void Change_Nick PARAMS((CLIENT * Origin, CLIENT * Target, char *NewNick, + bool InformClient)); /** @@ -278,7 +278,8 @@ IRC_NICK( CLIENT *Client, REQUEST *Req ) Client_SetType( Client, CLIENT_GOTNICK ); } else { /* Nickname change */ - Change_Nick(Client, target, Req->argv[0], true); + Change_Nick(Client, target, Req->argv[0], + Client_Type(Client) == CLIENT_USER ?
