- When checking if a user is banned, we always check the cloakhost too. Previously we could not do this if the user had a /VHOST (=a minority of the cases, but still...). In short, this is some extra protection to combat ban evasion. - Performance of is_banned() *slightly* improved (just 1-2 usec, but 7 usec if no bans). - [Module coders] For extban routines, we now offer a routine extban_is_banned_helper(buf) which can be used instead of the ban_realhost/etc static chars stuff, see extban_modeq_is_banned for a (real-life) example of how this is used. - [Services coders!] Added PROTOCTL CLK (requires NICKv2) which adds an extra field in the NICK command (when a user connects) right before the infofield (gecos). The added field contains the cloaked host, that is: the masked host if +x would have been set. This field is ALWAYS sent, regardless of whether the user is actually +x or not. Services can then store this field in memory, to know the host of the user if the user is set +x (+x-t). This is a (better) alternative to PROTOCTL VHP, with no race conditions, and avoids some other VHP problems. VHP will stay supported though... so it's not mandatory to switch over.
