MODE <channel> <+|-><b|q|e|I> $[~]<type>[:<data>]

Extended bans (ban conditionals) allow different checks than the usual
nick!user@host or nick!user@ip match to determine whether someone should
be banned, quieted, exempted or invited.

Extended bans are of the form $[~]<type>[:<data>]. The <type> is one
character (case insensitive) and determines the type of match. Most types
allow or require an extra field <data>. If the tilde (~) is present, the
result of the comparison will be negated, unless the ban is invalid in which
case it will never match. Invalid bans are ones where <data> is missing but
required or where <data> is otherwise invalid as noted below.

Unless noted below, all types can be used with +b, +q, +e and +I.

 extb Type  - DESCRIPTION
------------------------------------------------------------------------
     $a     - Matches all logged in users
  $a:<mask> - Matches users logged in with a username matching the mask
              (* and ? wildcards)
  $c:<chan> - Matches users who are on the given channel
  $g:<mask> - Matches as a normal ban but excludes logged in users
     $o     - Matches opers (most useful with +I)
  $r:<mask> - Matches users with a realname (gecos) matching the mask
              (* and ? wildcards); this can only be used with +b and +q
  $s:<mask> - matches users connected to a server matching the mask
              (* and ? wildcards); this can only be used with +b and +q
  $j:<chan> - matches users who are or are not banned from a specified
              channel
  $x:<mask> - Bans all users with matching nick!user@host#gecos
     $z     - Matches all SSL users

extensions/extb_channel: Allow matching secret channels. This change modifies extb_channel to allow matching users in secret channels, which prevents trivial ban evasion by setting the target channel +s. Information leak due to this change is unlikely since the attacker would have to know that the target channel exists, the name of the channel (or guess it), have a specific user they wanted to know whether was in the channel (and not know already), and the target user would need to have something like autojoin-on-invite enabled (or any of the other various ways hostname cloaking is attacked). 2016-12-29 05:44:18 +00:00			`$c:<chan> - Matches users who are on the given channel`
Add extban type for unidentified connections (#411) * Add extension extb_guest This module provides an extban type that acts as a normal ban but only matches unidentified users. * Document extban g in help/opers/extban * extensions/extb_guest: support CIDR masks in $g extbans This allows a channel operator to set a channel ban such as "$g:!@192.0.2.0/24#web.libera.chat" and have it function as intended. --------- Co-authored-by: Aaron Jones <me@aaronmdjones.net> 2023-07-01 18:09:41 +00:00			`$g:<mask> - Matches as a normal ban but excludes logged in users`
