+- modules/m_sasl.c: don't process messages if SASL has been aborted
+- src/s_user.c: don't corrupt usermodes on module unload/reload
+
+### misc
+- modules/m_list.c: add fake /LIST reply output to help fight spambots
+
+## charybdis-3.5.6
+
+This is primarily a bugfix release.

+### security
+- doc/reference.conf: clarify: TLS server fingerprints are not optional
+- extensions/extb_ssl.c: add support for matching fingerprints
+- libratbox/src/mbedtls.c: check public/private keys match
+- libratbox/src/mbedtls.c: support ChaCha20-Poly1305 by default
+
+### user
+- libratbox/src/commio.c: fix accept() for IPv6 after dropping IPv4
+- src/client.c: don't delete servers from the client hash table
+- src/s_user.c: don't send fake MODE for clients with CHGHOST support
+- modules/m_sasl.c: abort session if we receive '*' as data
+- modules/m_sasl.c: check agent is present after every client exit
+
+### misc
+- configure: adjust dlopen/dlsym checks to work under libasan
+- configure: allow exact PID file prefix to be specified
+- doc/: convert SGML oper guide to RST
+- doc/: point users to HELP EXTBAN for inline help

+- gnutls TLS backend improvements from charybdis 4:
+  - make certfp support more reliable on newer gnutls versions
+  - avoid possible null dereference when constructing ciphersuites
+- openssl TLS backend improvements from charybdis 4:
+  - avoid a possible use-after-free issue when newer openssl versions cannot load keypairs in a rehash
+  - improve compatibility with libressl
+  - more robustly load DH parameters files
+- daemonization improvements from charybdis 4
+
+## charybdis-3.5.2
+
+### user
+- Allow IRCv3.1 STARTTLS to work with other SSL backends besides OpenSSL.
+- Fix an edge case regression involving channel ban cache that was introduced in 3.5.0.
+
+### misc

+Channel modes
+=============
+
+Channel modes are determined by the various plugins loaded by the
+server. The following consists only of a base list of common modes:
+your server may have more plugins available, which you can see with
+the following server command, depending on your IRC client::
+
+  /QUOTE HELP CMODE
+
+or::
+
+  /RAW HELP CMODE
+
+``+b``, channel ban
+-------------------
+
+Bans take one parameter which can take several forms. The most common
+form is ``+b nick!user@host``. The wildcards ``*`` and ``?`` are
+allowed, matching zero-or-more, and exactly-one characters
+respectively. The masks will be trimmed to fit the maximum allowable
+length for the relevant element.  Bans are also checked against the IP
+address, even if it resolved or is spoofed. CIDR is supported, like
+``*!*@10.0.0.0/8``. This is most useful with IPv6. Bans are not
+checked against the real hostname behind any kind of spoof, except if
+host mangling is in use (e.g.  ``extensions/ip_cloaking.so``): if the
+user's host is mangled, their real hostname is checked additionally,
+and if a user has no spoof but could enable mangling, the mangled form
+of their hostname is checked additionally. Hence, it is not possible
+to evade bans by toggling host mangling.
+
+The second form (extban) is ``+b $type`` or ``+b $type:data``. type is
+a single character (case insensitive) indicating the type of match,
+optionally preceded by a tilde (``~``) to negate the comparison. data
+depends on type.  Each type is loaded as a module. The available types
+(if any) are listed in the ``EXTBAN`` token of the 005
+(``RPL_ISUPPORT``) numeric. See ``doc/extban.txt`` in the source
+distribution or ``HELP EXTBAN`` for more information.
+
+If no parameter is given, the list of bans is returned. All users can
+use this form. The plus sign should also be omitted.
+
+Matching users will not be allowed to join the channel or knock on it.
+If they are already on the channel, they may not send to it or change
+their nick.
+
+``+c``, colour filter
+---------------------
+
+This cmode activates the colour filter for the channel. This filters out
+bold, underline, reverse video, beeps, mIRC colour codes, and ANSI
+escapes. Note that escape sequences will usually leave cruft sent to the
+channel, just without the escape characters themselves.
+
+``+e``, ban exemption
+---------------------
+
+This mode takes one parameter of the same form as bans, which overrides
+``+b`` and ``+q`` bans for all clients it matches.
+
+This can be useful if it is necessary to ban an entire ISP due to
+persistent abuse, but some users from that ISP should still be allowed
+in. For example::
+
+  /mode #channel +be *!*@*.example.com *!*someuser@host3.example.com
+
+Only channel operators can see ``+e`` changes or request the list.
+
+``+f``, channel forwarding
+--------------------------
+
+This mode takes one parameter, the name of a channel (``+f
+#channel``). If the channel also has the ``+i`` cmode set, and
+somebody attempts to join without either being expliticly invited, or
+having an invex (``+I``), then they will instead join the channel
+named in the mode parameter. The client will also be sent a 470
+numeric giving the original and target channels.
+
+Users are similarly forwarded if the ``+j`` cmode is set and their attempt
+to join is throttled, if ``+l`` is set and there are already too many users
+in the channel or if ``+r`` is set and they are not identified.
+
+Forwards may only be set to ``+F`` channels, or to channels the setter has
+ops in.
+
+Without parameter (``/mode #channel f`` or ``/mode #channel +f``) the forward
+channel is returned. This form also works off channel.
+
+``+F``, allow anybody to forward to this
+----------------------------------------
+
+When this mode is set, anybody may set a forward from a channel they
+have ops in to this channel. Otherwise they have to have ops in this
+channel.
+
+``+g``, allow anybody to invite
+-------------------------------
+
+When this mode is set, anybody may use the ``INVITE`` command on the channel
+in question. When it is unset, only channel operators may use the ``INVITE``
+command.
+
+When this mode is set together with ``+i``, ``+j``, ``+l`` or ``+r``, all channel
+members can influence who can join.
+
+``+i``, invite only
+-------------------
+
+When this cmode is set, no client can join the channel unless they have
+an invex (``+I``) or are invited with the ``INVITE`` command.
+
+``+I``, invite exception (invex)
+--------------------------------
+
+This mode takes one parameter of the same form as bans. Matching clients
+do not need to be invited to join the channel when it is invite-only
+(``+i``). Unlike the ``INVITE`` command, this does not override ``+j``, ``+l`` and ``+r``.
+
+Only channel operators can see ``+I`` changes or request the list.
+
+``+j``, join throttling
+-----------------------
+
+This mode takes one parameter of the form n:t, where n and t are
+positive integers. Only n users may join in each period of t seconds.
+
+Invited users can join regardless of ``+j``, but are counted as normal.
+
+Due to propagation delays between servers, more users may be able to
+join (by racing for the last slot on each server).
+
+``+k``, key (channel password)
+------------------------------
+
+Taking one parameter, when set, this mode requires a user to supply the
+key in order to join the channel: ``/JOIN #channel key``.
+
+``+l``, channel member limit
+----------------------------
+
+Takes one numeric parameter, the number of users which are allowed to be
+in the channel before further joins are blocked. Invited users may join
+regardless.
+
+Due to propagation delays between servers, more users may be able to
+join (by racing for the last slot on each server).
+
+``+L``, large ban list
+----------------------
+
+Channels with this mode will be allowed larger banlists (by default, 500
+instead of 50 entries for ``+b``, ``+q``, ``+e`` and ``+I`` together). Only network
+operators with resv privilege may set this mode.
+
+``+m``, moderated
+-----------------
+
+When a channel is set ``+m``, only users with ``+o`` or ``+v`` on the channel can
+send to it.
+
+Users can still knock on the channel or change their nick.
+
+``+n``, no external messages
+----------------------------
+
+When set, this mode prevents users from sending to the channel without
+being in it themselves. This is recommended.
+
+``+o``, channel operator
+------------------------
+
+This mode takes one parameter, a nick, and grants or removes channel
+operator privilege to that user. Channel operators have full control
+over the channel, having the ability to set all channel modes except ``+L``
+and ``+P``, and kick users. Like voiced users, channel operators can always
+send to the channel, overriding ``+b``, ``+m`` and ``+q`` modes and the per-channel
+flood limit. In most clients channel operators are marked with an '@'
+sign.
+
+The privilege is lost if the user leaves the channel or server in any
+way.
+
+Most networks will run channel registration services (e.g. ChanServ)
+which ensure the founder (and users designated by the founder) can
+always gain channel operator privileges and provide some features to
+manage the channel.
+
+``+p``, paranoid channel
+------------------------
+
+When set, the ``KNOCK`` command cannot be used on the channel to request an
+invite, and users will not be shown the channel in ``WHOIS`` replies unless
+they are on it. Unlike in traditional IRC, ``+p`` and ``+s`` can be set
+together.
+
+``+P``, permanent channel
+-------------------------
+
+Channels with this mode (which is accessible only to network operators
+with resv privilege) set will not be destroyed when the last user
+leaves.
+
+This makes it less likely modes, bans and the topic will be lost and
+makes it harder to abuse network splits, but also causes more unwanted
+restoring of old modes, bans and topics after long splits.
+
+``+q``, quiet
+-------------
+
+This mode behaves exactly like ``+b`` (ban), except that the user may still
+join the channel. The net effect is that they cannot knock on the
+channel, send to the channel or change their nick while on channel.
+
+``+Q``, block forwarded users
+-----------------------------
+
+Channels with this mode set are not valid targets for forwarding. Any
+attempt to forward to this channel will be ignored, and the user will be
+handled as if the attempt was never made (by sending them the relevant
+error message).
+
+This does not affect the ability to set ``+f``.
+
+``+r``, block unidentified
+--------------------------
+
+When set, this mode prevents unidentified users from joining. Invited
+users can still join.
+
+``+s``, secret channel
+----------------------
+
+When set, this mode prevents the channel from appearing in the output of
+the ``LIST``, ``WHO`` and ``WHOIS`` command by users who are not on it. Also, the
+server will refuse to answer ``WHO``, ``NAMES``, ``TOPIC`` and ``LIST`` queries from
+users not on the channel.
+
+``+t``, topic limit
+-------------------
+
+When set, this mode prevents users who are not channel operators from
+changing the topic.
+
+``+v``, voice
+-------------
+
+This mode takes one parameter, a nick, and grants or removes voice
+privilege to that user. Voiced users can always send to the channel,
+overriding ``+b``, ``+m`` and ``+q`` modes and the per-channel flood limit. In most
+clients voiced users are marked with a plus sign.
+
+The privilege is lost if the user leaves the channel or server in any
+way.
+
+``+z``, reduced moderation
+--------------------------
+
+When ``+z`` is set, the effects of ``+m``, ``+b`` and ``+q`` are relaxed. For each
+message, if that message would normally be blocked by one of these
+modes, it is instead sent to all channel operators. This is intended for
+use in moderated debates.
+
+Note that ``+n`` is unaffected by this. To silence a given user completely,
+remove them from the channel.

+Operator Commands
+=================
+
+Network management commands
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. note:: All commands and names are case insensitive. Parameters
+          consisting of one or more separate letters, such as in ``MODE``,
+          ``STATS`` and ``WHO``, are case sensitive.
+
+CONNECT
+-------
+
+::
+
+   CONNECT target [port] [source]
+
+Initiate a connection attempt to server target. If a port is given,
+connect to that port on the target, otherwise use the one given in
+``ircd.conf``. If source is given, tell that server to initiate the
+connection attempt, otherwise it will be made from the server you are
+attached to.
+
+To use the default port with source, specify 0 for port.
+
+SQUIT
+-----
+
+::
+
+   SQUIT server [reason]
+
+Closes down the link to server from this side of the network. If a
+reason is given, it will be sent out in the server notices on both sides
+of the link.
+
+REHASH
+------
+
+::
+
+   REHASH [BANS | DNS | MOTD | OMOTD | TKLINES | TDLINES | TXLINES | TRESVS | REJECTCACHE | HELP] [server]
+
+With no parameter given, ``ircd.conf`` will be reread and parsed. The
+server argument is a wildcard match of server names.
+
+``BANS``
+    Rereads ``kline.conf``, ``dline.conf``, ``xline.conf``,
+    ``resv.conf`` and their .perm variants
+
+``DNS``
+    Reread ``/etc/resolv.conf``.
+
+``MOTD``
+    Reload the ``MOTD`` file
+
+``OMOTD``
+    Reload the operator ``MOTD`` file
+
+``TKLINES``
+    Clears temporary ``K:lines``.
+
+``TDLINES``
+    Clears temporary ``D:lines``.
+
+``TXLINES``
+    Clears temporary ``X:lines``.
+
+``TRESVS``
+    Clears temporary reservations.
+
+``REJECTCACHE``
+    Clears the client rejection cache.
+
+``HELP``
+    Refreshes the help system cache.
+
+RESTART
+-------
+
+::
+
+   RESTART server
+
+Cause an immediate total shutdown of the IRC server, and restart from
+scratch as if it had just been executed.
+
+This reexecutes the ircd using the compiled-in path, visible as ``SPATH`` in
+``INFO``.
+
+.. note:: This command cannot be used remotely. The server name is
+          used only as a safety measure.
+
+DIE
+---
+
+::
+
+   DIE server
+
+Immediately terminate the IRC server, after sending notices to all
+connected clients and servers
+
+.. note:: This command cannot be used remotely. The server name is
+          used only as a safety measure.
+
+SET
+---
+
+::
+
+   SET [ ADMINSTRING | AUTOCONN | AUTOCONNALL | FLOODCOUNT | IDENTTIMEOUT | MAX | OPERSTRING | SPAMNUM | SPAMTIME | SPLITMODE | SPLITNUM | SPLITUSERS ] value
+
+The ``SET`` command sets a runtime-configurable value.
+
+Most of the ``ircd.conf`` equivalents have a ``default_prefix`` and are
+only read on startup. ``SET`` is the only way to change these at run time.
+
+Most of the values can be queried by omitting value.
+
+``ADMINSTRING``
+    Sets string shown in ``WHOIS`` for admins. (umodes +o and +a set, umode
+    +S not set).
+
+``AUTOCONN``
+    Sets auto-connect on or off for a particular server. Takes two
+    parameters, server name and new state.
+
+    To see these values, use ``/stats c``. Changes to this are lost on a
+    rehash.
+
+``AUTOCONNALL``
+    Globally sets auto-connect on or off. If disabled, no automatic
+    connections are done; if enabled, automatic connections are done
+    following the rules for them.
+
+``FLOODCOUNT``
+    The number of lines allowed to be sent to a connection before
+    throttling it due to flooding. Note that this variable is used for
+    both channels and clients.
+
+    For channels, op or voice overrides this; for users, IRC operator
+    status or op or voice on a common channel overrides this.
+
+``IDENTTIMEOUT``
+    Timeout for requesting ident from a client.
+
+``MAX``
+    Sets the maximum number of connections to value.
+
+    This number cannot exceed maxconnections - ``MAX_BUFFER``.
+    maxconnections is the rlimit for number of open files. ``MAX_BUFFER``
+    is defined in config.h, normally 60.
+
+    ``MAXCLIENTS`` is an alias for this.
+
+``OPERSTRING``
+    Sets string shown in ``WHOIS`` for opers (umode ``+o`` set, umodes ``+a`` and ``+S``
+    not set).
+
+``SPAMNUM``
+    Sets how many join/parts to channels constitutes a possible spambot.
+
+``SPAMTIME``
+    Below this time on a channel counts as a join/part as above.
+
+``SPLITMODE``
+    Sets splitmode to value:
+
+    ``ON``
+        splitmode is permanently on
+
+    ``OFF``
+        splitmode is permanently off (default if ``no_create_on_split``
+        and ``no_join_on_split`` are disabled)
+
+    ``AUTO``
+        ircd chooses splitmode based on ``SPLITUSERS`` and ``SPLITNUM`` (default
+        if ``no_create_on_split`` or ``no_join_on_split`` are enabled)
+
+``SPLITUSERS``
+    Sets the minimum amount of users needed to deactivate automatic
+    splitmode.
+
+``SPLITNUM``
+    Sets the minimum amount of servers needed to deactivate automatic
+    splitmode. Only servers that have finished bursting count for this.
+
+User management commands
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+KILL
+----
+
+::
+
+   KILL nick [reason]
+
+Disconnects the user with the given nick from the server they are
+connected to, with the reason given, if present, and broadcast a server
+notice announcing this.
+
+Your nick and the reason will appear on channels.
+
+CLOSE
+-----
+
+Closes all connections from and to clients and servers who have not
+completed registering.
+
+KLINE
+-----
+
+::
+
+   KLINE [length] [user@host | user@a.b.c.d] [ON servername] [:reason]
+
+Adds a ``K:line`` to ``kline.conf`` to ban the given ``user@host`` from using
+that server.
+
+If the optional parameter length is given, the ``K:line`` will be temporary
+(i.e. it will not be stored on disk) and last that long in minutes.
+
+If an IP address is given, the ban will be against all hosts matching
+that IP regardless of DNS. The IP address can be given as a full address
+(``192.168.0.1``), as a CIDR mask (``192.168.0.0/24``), or as a glob
+(``192.168.0.*``).
+
+All clients matching the ``K:line`` will be disconnected from the server
+immediately.
+
+If a reason is specified, it will be sent to the client when they are
+disconnected, and whenever a connection is attempted which is banned.
+
+If the ON part is specified, the ``K:line`` is set on servers matching the
+given mask (provided a matching ``shared{}`` block exists there). Otherwise,
+if specified in a ``cluster{}`` block, the ``K:Line`` will be propagated across
+the network accordingly.
+
+UNKLINE
+-------
+
+::
+
+   UNKLINE user@host [ON servername]
+
+Will attempt to remove a ``K:line`` matching ``user@host`` from ``kline.conf``,
+and will flush a temporary ``K:line``.
+
+XLINE
+-----
+
+::
+
+   XLINE [length] mask [ON servername] [:reason]
+
+Works similarly to ``KLINE``, but matches against the real name field. The
+wildcards are ``*`` (any sequence), ``?`` (any character), ``#`` (a digit) and ``@`` (a
+letter); wildcard characters can be escaped with a backslash. The
+sequence ``\s`` matches a space.
+
+All clients matching the ``X:line`` will be disconnected from the server
+immediately.
+
+The reason is never sent to users. Instead, they will be exited with
+"Bad user info".
+
+If the ON part is specified, the ``X:line`` is set on servers matching the
+given mask (provided a matching ``shared{}`` block exists there). Otherwise,
+if specified in a ``cluster{}`` block, the ``X:line`` will be propagated across
+the network accordingly.
+
+UNXLINE
+-------
+
+::
+
+   UNXLINE mask [ON servername]
+
+Will attempt to remove an ``X:line`` from ``xline.conf``, and will flush a
+temporary ``X:line``.
+
+RESV
+----
+
+::
+
+   RESV [length] [channel | mask] [ON servername] [:reason]
+
+If used on a channel, “jupes” the channel locally. Joins to the channel
+will be disallowed and generate a server notice on ``+y``, and users will
+not be able to send to the channel. Channel jupes cannot contain
+wildcards.
+
+If used on a nickname mask, prevents local users from using a nick
+matching the mask (the same wildcard characters as xlines). There is no
+way to exempt the initial nick from this.
+
+In neither case will current users of the nick or channel be kicked or
+disconnected.
+
+This facility is not designed to make certain nicks or channels
+oper-only.
+
+The reason is never sent to users.
+
+If the ON part is specified, the resv is set on servers matching the
+given mask (provided a matching ``shared{}`` block exists there). Otherwise,
+if specified in a ``cluster{}`` block, the resv will be propagated across
+the network accordingly.
+
+UNRESV
+------
+
+::
+
+   UNRESV [channel | mask] [ON servername]
+
+Will attempt to remove a resv from ``resv.conf``, and will flush a
+temporary resv.
+
+DLINE
+-----
+
+::
+
+   DLINE [length] a.b.c.d [ON servername] [:reason]
+
+Adds a ``D:line`` to ``dline.conf``, which will deny any connections from
+the given IP address. The IP address can be given as a full address
+(``192.168.0.1``) or as a CIDR mask (``192.168.0.0/24``).
+
+If the optional parameter length is given, the ``D:line`` will be temporary
+(i.e. it will not be stored on disk) and last that long in minutes.
+
+All clients matching the ``D:line`` will be disconnected from the server
+immediately.
+
+If a reason is specified, it will be sent to the client when they are
+disconnected, and, if ``dline_reason`` is enabled, whenever a connection is
+attempted which is banned.
+
+``D:lines`` are less load on a server, and may be more appropriate if
+somebody is flooding connections.
+
+If the ON part is specified, the ``D:line`` is set on servers matching the
+given mask (provided a matching ``shared{}`` block exists there, which is
+not the case by default). Otherwise, the D:Line will be set on the local
+server only.
+
+Only ``exempt{}`` blocks exempt from ``D:lines``. Being a server or having
+``kline_exempt`` in ``auth{}`` does *not* exempt (different from ``K/G/X:lines``).
+
+UNDLINE
+-------
+
+::
+
+   UNDLINE a.b.c.d [ON servername]
+
+Will attempt to remove a ``D:line`` from ``dline.conf``, and will flush a
+temporary ``D:line``.
+
+TESTGECOS
+---------
+
+::
+
+   TESTGECOS gecos
+
+Looks up X:Lines matching the given gecos.
+
+TESTLINE
+--------
+
+::
+
+   TESTLINE [nick!] [user@host | a.b.c.d]
+
+Looks up the given hostmask or IP address and reports back on any ``auth{}``
+blocks, D: or K: lines found. If nick is given, also searches for nick
+resvs.
+
+For temporary items the number of minutes until the item expires is
+shown (as opposed to the hit count in STATS q/Q/x/X).
+
+This command will not perform DNS lookups; for best results you must
+testline a host and its IP form.
+
+The given username should begin with a tilde (~) if identd is not in
+use. As of charybdis 2.1.1, ``no_tilde`` and username truncation will be
+taken into account like in the normal client access check.
+
+As of charybdis 2.2.0, a channel name can be specified and the RESV will
+be returned, if there is one.
+
+TESTMASK
+--------
+
+::
+
+   TESTMASK hostmask [gecos]
+
+Searches the network for users that match the hostmask and gecos given,
+returning the number of matching users on this server and other servers.
+
+The hostmask is of the form user@host or user@ip/cidr with \* and ?
+wildcards, optionally preceded by nick!.
+
+The gecos field accepts the same wildcards as xlines.
+
+The IP address checked against is ``255.255.255.255`` if the IP address is
+unknown (remote client on a TS5 server) or 0 if the IP address is hidden
+(``auth{}`` spoof).
+
+LUSERS
+------
+
+::
+   
+   LUSERS [mask] [nick | server]
+
+Shows various user and channel counts.
+
+The mask parameter is obsolete but must be used when querying a remote
+server.
+
+TRACE
+-----
+
+::
+
+   TRACE [server | nick] [location]
+
+With no argument or one argument which is the current server, TRACE
+gives a list of all connections to the current server and a summary of
+connection classes.
+
+With one argument which is another server, TRACE displays the path to
+the specified server, and all servers, opers and -i users on that
+server, along with a summary of connection classes.
+
+With one argument which is a client, TRACE displays the path to that
+client, and that client's information.
+
+If location is given, the command is executed on that server; no path is
+displayed.
+
+When listing connections, type, name and class is shown in addition to
+information depending on the type:
+
+Try.
+    A server we are trying to make a TCP connection to.
+
+H.S.
+    A server we have established a TCP connection to, but is not yet
+    registered.
+
+\?\?\?\?
+    An incoming connection that has not yet registered as a user or a
+    server (“unknown”). Shows the username, hostname, IP address and the
+    time the connection has been open. It is possible that the ident or
+    DNS lookups have not completed yet, and in any case no tildes are
+    shown here. Unknown connections may not have a name yet.
+
+User
+    A registered unopered user. Shows the username, hostname, IP
+    address, the time the client has not sent anything (as in STATS l)
+    and the time the user has been idle (from PRIVMSG only, as in
+    WHOIS).
+
+Oper
+    Like User, but opered.
+
+Serv
+    A registered server. Shows the number of servers and users reached
+    via this link, who made this connection and the time the server has
+    not sent anything.
+
+ETRACE
+------
+
+::
+
+   ETRACE [nick]
+
+Shows client information about the given target, or about all local
+clients if no target is specified.
+
+PRIVS
+-----
+
+::
+
+   PRIVS [nick]
+
+Displays effective operator privileges for the specified nick, or for
+yourself if no nick is given. This includes all privileges from the
+operator block, the name of the operator block and those privileges from
+the auth block that have an effect after the initial connection.
+
+The exact output depends on the server the nick is on, see the matching
+version of this document. If the remote server does not support this
+extension, you will not receive a reply.
+
+MASKTRACE
+---------
+
+::
+
+   MASKTRACE hostmask [gecos]
+
+Searches the local server or network for users that match the hostmask
+and gecos given. Network searches require the ``oper_spy`` privilege and an
+'!' before the hostmask. The matching works the same way as TESTMASK.
+
+The hostmask is of the form ``user@host`` or ``user@ip/cidr`` with ``*`` and ``?``
+wildcards, optionally preceded by ``nick!``.
+
+The gecos field accepts the same wildcards as xlines.
+
+The IP address field contains ``255.255.255.255`` if the IP address is
+unknown (remote client on a TS5 server) or ``0`` if the IP address is hidden
+(``auth{}`` spoof).
+
+CHANTRACE
+---------
+
+::
+
+   CHANTRACE channel
+
+Displays information about users in a channel. Opers with the ``oper_spy``
+privilege can get the information without being on the channel, by
+prefixing the channel name with an ``!``.
+
+The IP address field contains ``255.255.255.255`` if the IP address is
+unknown (remote client on a TS5 server) or ``0`` if the IP address is hidden
+(``auth{}`` spoof).
+
+SCAN
+----
+
+::
+
+   SCAN UMODES +modes-modes [no-list] [list] [global] [list-max number] [mask nick!user@host]
+
+Searches the local server or network for users that have the umodes
+given with + and do not have the umodes given with -. no-list disables
+the listing of matching users and only shows the count. list enables the
+listing (default). global extends the search to the entire network
+instead of local users only. list-max limits the listing of matching
+users to the given amount. mask causes only users matching the given
+nick!user@host mask to be selected. Only the displayed host is
+considered, not the IP address or real host behind dynamic spoofs.
+
+The IP address field contains ``255.255.255.255`` if the IP address is
+unknown (remote client on a TS5 server) or 0 if the IP address is hidden
+(``auth{}`` spoof).
+
+Network searches where a listing is given are operspy commands.
+
+CHGHOST
+-------
+
+::
+
+   CHGHOST nick value
+
+Set the hostname associated with a particular nick for the duration of
+this session. This command is disabled by default because of the abuse
+potential and little practical use.
+
+Miscellaneous commands
+~~~~~~~~~~~~~~~~~~~~~~
+
+ADMIN
+-----
+
+::
+
+   ADMIN [nick | server]
+
+Shows the information in the ``admin{}`` block.
+
+INFO
+----
+
+::
+
+   INFO [nick | server]
+
+Shows information about the authors of the IRC server, and some
+information about this server instance. Opers also get a list of
+configuration options.
+
+TIME
+----
+
+::
+
+   TIME [nick | server]
+
+Shows the local time on the given server, in a human-readable format.
+
+VERSION
+-------
+
+::
+
+   VERSION [nick | server]
+
+Shows version information, a few compile/config options, the SID and the
+005 numerics. The 005 numeric will be remapped to 105 for remote
+requests.

+WALLOPS
+-------
+
+::
+
+   WALLOPS :message
+
+Sends a WALLOPS message to all users who have the +w umode set. This is

+
+OPERWALL
+--------
+
+::
+
+   OPERWALL :message
+
+Sends an OPERWALL message to all opers who have the +z umode set. +z is
+restricted, OPERWALL should be considered private communications.

+Server config file format
+=========================
+
+General format
+~~~~~~~~~~~~~~
+
+The config file consists of a series of BIND-style blocks. Each block
+consists of a series of values inside it which pertain to configuration
+settings that apply to the given block.
+
+Several values take lists of values and have defaults preset inside
+them. Prefix a keyword with a tilde (``~``) to override the default and
+disable it.
+
+A line may also be a .include directive, which is of the form::
+
+  .include "file"
+
+and causes file to be read in at that point, before the rest of
+the current file is processed. Relative paths are first tried relative
+to ``PREFIX`` and then relative to ``ETCPATH`` (normally ``PREFIX``/etc).
+
+Anything from a ``#`` to the end of a line is a comment. Blank lines are
+ignored. C-style comments are also supported.
+
+Specific blocks and directives
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Not all configuration blocks and directives are listed here, only the
+most common ones. More blocks and directives will be documented in later
+revisions of this manual.
+
+loadmodule directive
+--------------------
+
+::
+
+   loadmodule "text";
+
+Loads a module into the IRCd. In charybdis 1.1, most modules are
+automatically loaded in. In future versions, it is intended to remove
+this behaviour as to allow for easy customization of the IRCd's
+featureset.
+
+serverinfo {} block
+-------------------
+
+::
+
+   serverinfo {
+        name = "text";
+        sid = "text";
+        description = "text";
+        network_name = "text";
+        network_desc = "text";
+        hub = boolean;
+        vhost = "text";
+        vhost6 = "text";
+   };
+
+The serverinfo {} block defines the core operational parameters of the
+IRC server.
+
+**serverinfo {} variables**
+
+name
+    The name of the IRC server that you are configuring. This must
+    contain at least one dot. It is not necessarily equal to any DNS
+    name. This must be unique on the IRC network.
+
+sid
+    A unique ID which describes the server. This consists of one digit
+    and two characters which can be digits or letters.
+
+description
+    A user-defined field of text which describes the IRC server. This
+    information is used in ``/links`` and ``/whois`` requests. Geographical
+    location information could be a useful use of this field, but most
+    administrators put a witty saying inside it instead.
+
+network\_name
+    The name of the IRC network that this server will be a member of.
+    This is used in the welcome message and ``NETWORK=`` in 005.
+
+hub
+    A boolean which defines whether or not this IRC server will be
+    serving as a hub, i.e. have multiple servers connected to it.
+
+vhost
+    An optional text field which defines an IP from which to connect
+    outward to other IRC servers.
+
+vhost6
+    An optional text field which defines an IPv6 IP from which to
+    connect outward to other IRC servers.
+
+admin {} block
+--------------
+
+::
+
+   admin {
+       name = "text";
+	   description = "text";
+	   email = "text";
+   };
+
+This block provides the information which is returned by the ``ADMIN``
+command.
+
+name
+    The name of the administrator running this service.
+
+description
+    The description of the administrator's position in the network.
+
+email
+    A point of contact for the administrator, usually an e-mail address.
+
+class {} block
+--------------
+
+::
+
+    class "name" {
+            ping_time = duration;
+            number_per_ident = number;
+            number_per_ip = number;
+            number_per_ip_global = number;
+            cidr_ipv4_bitlen = number;
+            cidr_ipv6_bitlen = number;
+            number_per_cidr = number;
+            max_number = number;
+            sendq = size;
+    };
+    
+    class "name" {
+            ping_time = duration;
+            connectfreq = duration;
+            max_number = number;
+            sendq = size;
+    };    
+   
+Class blocks define classes of connections for later use. The class name
+is used to connect them to other blocks in the config file (auth{} and
+connect{}). They must be defined before they are used.
+
+Classes are used both for client and server connections, but most
+variables are different.
+
+**class {} variables: client classes**
+
+ping\_time
+    The amount of time between checking pings for clients, e.g.: 2
+    minutes
+
+number\_per\_ident
+    The amount of clients which may be connected from a single identd
+    username on a per-IP basis, globally. Unidented clients all count as
+    the same username.
+
+number\_per\_ip
+    The amount of clients which may be connected from a single IP
+    address.
+
+number\_per\_ip\_global
+    The amount of clients which may be connected globally from a single
+    IP address.
+
+cidr\_ipv4\_bitlen
+    The netblock length to use with CIDR-based client limiting for IPv4
+    users in this class (between 0 and 32).
+
+cidr\_ipv6\_bitlen
+    The netblock length to use with CIDR-based client limiting for IPv6
+    users in this class (between 0 and 128).
+
+number\_per\_cidr
+    The amount of clients which may be connected from a single netblock.
+
+    If this needs to differ between IPv4 and IPv6, make different
+    classes for IPv4 and IPv6 users.
+
+max\_number
+    The maximum amount of clients which may use this class at any given
+    time.
+
+sendq
+    The maximum size of the queue of data to be sent to a client before
+    it is dropped.
+
+**class {} variables: server classes**
+
+ping\_time
+    The amount of time between checking pings for servers, e.g.: 2
+    minutes
+
+connectfreq
+    The amount of time between autoconnects. This must at least be one
+    minute, as autoconnects are evaluated with that granularity.
+
+max\_number
+    The amount of servers to autoconnect to in this class. More
+    precisely, no autoconnects are done if the number of servers in this
+    class is greater than or equal max\_number
+
+sendq
+    The maximum size of the queue of data to be sent to a server before
+    it is dropped.
+
+auth {} block
+-------------
+
+::
+
+    auth {
+    	user = "hostmask";
+    	password = "text";
+    	spoof = "text";
+    	flags = list;
+    	class = "text";
+    };
+
+auth {} blocks allow client connections to the server, and set various
+properties concerning those connections.
+
+Auth blocks are evaluated from top to bottom in priority, so put special
+blocks first.
+
+auth {} variables
+~~~~~~~~~~~~~~~~~
+
+user
+    A hostmask (``user@host``) that the auth {} block applies to. It is
+    matched against the hostname and IP address (using :: shortening for
+    IPv6 and prepending a 0 if it starts with a colon) and can also use
+    CIDR masks. You can have multiple user entries.
+
+password
+    An optional password to use for authenticating into this auth{}
+    block. If the password is wrong the user will not be able to connect
+    (will not fall back on another auth{} block).
+
+spoof
+    An optional fake hostname (or ``user@host``) to apply to users
+    authenticated to this auth{} block. In ``STATS i`` and ``TESTLINE``, an
+    equals sign (=) appears before the ``user@host`` and the spoof is shown.
+
+flags
+    A list of flags to apply to this ``auth{}`` block. They are listed
+    below. Some of the flags appear as a special character,
+    parenthesized in the list, before the ``user@host`` in ``STATS i`` and
+    ``TESTLINE``.
+
+class
+    A name of a class to put users matching this auth{} block into.
+
+auth {} flags
+~~~~~~~~~~~~~
+
+encrypted
+    The password used has been encrypted.
+
+spoof\_notice
+    Causes the IRCd to send out a server notice when activating a spoof
+    provided by this auth{} block.
+
+exceed\_limit (>)
+    Users in this auth{} block can exceed class-wide limitations.
+
+dnsbl\_exempt ($)

+    Users in this auth{} block may use reserved nicknames and channels.
+
+    .. note:: The initial nickname may still not be reserved.
+          
+flood\_exempt (\|) Users in this auth{} block may send arbitrary

+
+exempt {} block
+---------------
+
+::
+
+    exempt {
+    	ip = "ip";
+    };
+
+An exempt block specifies IP addresses which are exempt from ``D:lines`` and
+throttling. Multiple addresses can be specified in one block. Clients
+coming from these addresses can still be ``K/G/X:lined`` or banned by a DNS
+blacklist unless they also have appropriate flags in their auth{} block.
+
+**exempt {} variables**
+
+ip
+    The IP address or CIDR range to exempt.
+
+privset {} block
+----------------
+
+::
+   
+    privset {
+    	extends = "name";
+    	privs = list;
+    };
+
+A privset (privilege set) block specifies a set of operator privileges.
+
+**privset {} variables**
+
+extends
+    An optional privset to inherit. The new privset will have all
+    privileges that the given privset has.
+
+privs
+    Privileges to grant to this privset. These are described in the
+    operator privileges section.
+
+operator {} block
+-----------------
+
+::
+
+   operator "name" {
+    	user = "hostmask";
+    	password = "text";
+    	rsa_public_key_file = "text";
+    	umodes = list;
+    	snomask = "text";
+    	flags = list;
+   };
+
+Operator blocks define who may use the ``OPER`` command to gain extended
+privileges.
+
+**operator {} variables**
+
+user
+    A hostmask that users trying to use this operator {} block must
+    match. This is checked against the original host and IP address;
+    CIDR is also supported. So auth {} spoofs work in operator {}
+    blocks; the real host behind them is not checked. Other kind of
+    spoofs do not work in operator {} blocks; the real host behind them
+    is checked.
+
+    Note that this is different from charybdis 1.x where all kinds of
+    spoofs worked in operator {} blocks.
+
+password
+    A password used with the ``OPER`` command to use this operator {} block.
+    Passwords are encrypted by default, but may be unencrypted if
+    ~encrypted is present in the flags list.
+
+rsa\_public\_key\_file
+    An optional path to a RSA public key file associated with the
+    operator {} block. This information is used by the ``CHALLENGE``
+    command, which is an alternative authentication scheme to the
+    traditional ``OPER`` command.
+
+umodes
+    A list of usermodes to apply to successfully opered clients.
+
+snomask
+    An snomask to apply to successfully opered clients.
+
+privset
+    The privilege set granted to successfully opered clients. This must
+    be defined before this operator{} block.
+
+flags
+    A list of flags to apply to this operator{} block. They are listed
+    below.
+
+**operator {} flags**
+
+encrypted
+    The password used has been encrypted. This is enabled by default,
+    use ~encrypted to disable it.
+
+need\_ssl
+    Restricts use of this operator{} block to SSL/TLS connections only.
+
+connect {} block
+----------------
+
+::
+       
+    connect "name" {
+    	host = "text";
+    	send_password = "text";
+    	accept_password = "text";
+    	port = number;
+    	hub_mask = "mask";
+    	leaf_mask = "mask";
+    	class = "text";
+    	flags = list;
+    	aftype = protocol;
+    };
+
+Connect blocks define what servers may connect or be connected to.
+
+**connect {} variables**
+
+host
+    The hostname or IP to connect to.
+
+    .. note:: Furthermore, if a hostname is used, it must have an
+              ``A`` or ``AAAA`` record (no ``CNAME``) and it must be
+              the primary hostname for inbound connections to work.
+
+          IPv6 addresses must be in ``::`` shortened form; addresses which
+          then start with a colon must be prepended with a zero, for
+          example ``0::1``.
+
+send\_password
+    The password to send to the other server.
+
+accept\_password
+    The password that should be accepted from the other server.
+
+port
+    The port on the other server to connect to.
+
+hub\_mask
+    An optional domain mask of servers allowed to be introduced by this
+    link. Usually, "\*" is fine. Multiple hub\_masks may be specified,
+    and any of them may be introduced. Violation of hub\_mask and
+    leaf\_mask restrictions will cause the local link to be closed.
+
+leaf\_mask
+    An optional domain mask of servers not allowed to be introduced by
+    this link. Multiple leaf\_masks may be specified, and none of them
+    may be introduced. leaf\_mask has priority over hub\_mask.
+
+class
+    The name of the class this server should be placed into.
+
+flags
+    A list of flags concerning the connect block. They are listed below.
+
+aftype
+    The protocol that should be used to connect with, either ipv4 or
+    ipv6. This defaults to ipv4 unless host is a numeric IPv6 address.
+
+**connect {} flags**
+
+encrypted
+    The value for accept\_password has been encrypted.
+
+autoconn
+    The server should automatically try to connect to the server defined
+    in this connect {} block if it's not connected already and
+    max\_number in the class is not reached yet.
+
+compressed
+    Ziplinks should be used with this server connection. This compresses
+    traffic using zlib, saving some bandwidth and speeding up netbursts.
+
+    If you have trouble setting up a link, you should turn this off as
+    it often hides error messages.
+
+topicburst
+    Topics should be bursted to this server.
+
+    This is enabled by default.
+
+listen {} block
+---------------
+
+::
+
+   listen {
+    	host = "text";
+    	port = number;
+   };
+
+A listen block specifies what ports a server should listen on.
+
+**listen {} variables**
+
+host
+    An optional host to bind to. Otherwise, the ircd will listen on all
+    available hosts.
+
+port
+    A port to listen on. You can specify multiple ports via commas, and
+    define a range by seperating the start and end ports with two dots
+    (..).
+
+modules {} block
+----------------
+
+::
+   
+    modules {
+    	path = "text";
+    	module = text;
+    };
+
+The modules block specifies information for loadable modules.
+
+**modules {} variables**
+
+path
+    Specifies a path to search for loadable modules.
+
+module
+    Specifies a module to load, similar to loadmodule.
+
+general {} block
+----------------
+
+::
+
+    modules {
+    	values
+    };
+
+The general block specifies a variety of options, many of which were in
+``config.h`` in older daemons. The options are documented in
+``reference.conf``.
+
+channel {} block
+----------------
+
+::
+
+    modules {
+    	values
+    };
+
+The channel block specifies a variety of channel-related options, many
+of which were in ``config.h`` in older daemons. The options are
+documented in ``reference.conf``.
+
+serverhide {} block
+-------------------
+
+::
+
+    modules {
+    	values
+    };
+
+The serverhide block specifies options related to server hiding. The
+options are documented in ``reference.conf``.
+
+blacklist {} block
+------------------
+
+::
+
+    blacklist {
+    	host = "text";
+    	reject_reason = "text";
+    };
+
+The blacklist block specifies DNS blacklists to check. Listed clients
+will not be allowed to connect. IPv6 clients are not checked against
+these.
+
+Multiple blacklists can be specified, in pairs with first host then
+reject\_reason.
+
+**blacklist {} variables**
+
+host
+    The DNSBL to use.
+
+reject\_reason
+    The reason to send to listed clients when disconnecting them.
+
+alias {} block
+--------------
+
+::
+
+    alias "name" {
+    	target = "text";
+    };
+
+Alias blocks allow the definition of custom commands. These commands
+send ``PRIVMSG`` to the given target. A real command takes precedence above
+an alias.
+
+**alias {} variables**
+
+target
+    The target nick (must be a network service (umode ``+S``)) or
+    user@server. In the latter case, the server cannot be this server,
+    only opers can use user starting with "opers" reliably and the user
+    is interpreted on the target server only so you may need to use
+    nick@server instead).
+
+cluster {} block
+----------------
+
+::
+   
+    cluster {
+    	name = "text";
+    	flags = list;
+    };
+    
+The cluster block specifies servers we propagate things to
+automatically. This does not allow them to set bans, you need a separate
+shared{} block for that.
+
+Having overlapping cluster{} items will cause the command to be executed
+twice on the target servers. This is particularly undesirable for ban
+removals.
+
+The letters in parentheses denote the flags in ``/stats`` U.
+
+**cluster {} variables**
+
+name
+    The server name to share with, this may contain wildcards and may be
+    stacked.
+
+flags
+    The list of what to share, all the name lines above this (up to
+    another flags entry) will receive these flags. They are listed
+    below.
+
+**cluster {} flags**
+
+kline (K)
+    Permanent ``K:lines``
+
+tkline (k)
+    Temporary ``K:lines``
+
+unkline (U)
+    ``K:line`` removals
+
+xline (X)
+    Permanent ``X:lines``
+
+txline (x)
+    Temporary ``X:lines``
+
+unxline (Y)
+    ``X:line`` removals
+
+resv (Q)
+    Permanently reserved nicks/channels
+
+tresv (q)
+    Temporarily reserved nicks/channels
+
+unresv (R)
+    ``RESV`` removals
+
+locops (L)
+    ``LOCOPS`` messages (sharing this with \* makes ``LOCOPS`` rather similar to
+    ``OPERWALL`` which is not useful)
+
+all
+    All of the above
+
+shared {} block
+---------------
+
+::
+   
+    shared {
+    	oper = "user@host", "server";
+    	flags = list;
+    };
+
+The shared block specifies opers allowed to perform certain actions on
+our server remotely. These are ordered top down. The first one matching
+will determine the oper's access. If access is denied, the command will
+be silently ignored.
+
+The letters in parentheses denote the flags in ``/stats U``.
+
+**shared {} variables**
+
+oper
+    The user@host the oper must have, and the server they must be on.
+    This may contain wildcards.
+
+flags
+    The list of what to allow, all the oper lines above this (up to
+    another flags entry) will receive these flags. They are listed
+    below.
+
+    .. note:: While they have the same names, the flags have subtly
+              different meanings from those in the cluster{} block.
+
+**shared {} flags**
+
+kline (K)
+    Permanent and temporary ``K:lines``
+
+tkline (k)
+    Temporary ``K:lines``
+
+unkline (U)
+    ``K:line`` removals
+
+xline (X)
+    Permanent and temporary ``X:lines``
+
+txline (x)
+    Temporary ``X:lines``
+
+unxline (Y)
+    ``X:line`` removals
+
+resv (Q)
+    Permanently and temporarily reserved nicks/channels
+
+tresv (q)
+    Temporarily reserved nicks/channels
+
+unresv (R)
+    ``RESV`` removals
+
+all
+    All of the above; this does not include locops, rehash, dline,
+    tdline or undline.
+
+locops (L)
+    ``LOCOPS`` messages (accepting this from \* makes ``LOCOPS`` rather similar
+    to ``OPERWALL`` which is not useful); unlike the other flags, this can
+    only be accepted from \*@\* although it can be restricted based on
+    source server.
+
+rehash (H)
+    ``REHASH`` commands; all options can be used
+
+dline (D)
+    Permanent and temporary ``D:lines``
+
+tdline (d)
+    Temporary ``D:lines``
+
+undline (E)
+    ``D:line`` removals
+
+none
+    Allow nothing to be done
+
+service {} block
+----------------
+
+::
+
+    service {
+    	name = "text";
+    };
+
+The service block specifies privileged servers (services). These servers
+have extra privileges such as setting login names on users and
+introducing clients with umode ``+S`` (unkickable, hide channels, etc). This
+does not allow them to set bans, you need a separate shared{} block for
+that.
+
+Do not place normal servers here.
+
+Multiple names may be specified but there may be only one service{}
+block.
+
+**service {} variables**
+
+name
+    The server name to grant special privileges. This may not contain
+    wildcards.
+
+Hostname resolution (DNS)
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Charybdis uses solely DNS for all hostname/address lookups (no
+``/etc/hosts`` or anything else). The DNS servers are taken from
+``/etc/resolv.conf``. If this file does not exist or no valid IP
+addresses are listed in it, the local host (``127.0.0.1``) is used. (Note
+that the latter part did not work in older versions of Charybdis.)
+
+IPv4 as well as IPv6 DNS servers are supported, but it is not possible
+to use both IPv4 and IPv6 in ``/etc/resolv.conf``.
+
+For both security and performance reasons, it is recommended that a
+caching nameserver such as BIND be run on the same machine as Charybdis
+and that ``/etc/resolv.conf`` only list ``127.0.0.1``.

+Scope of this document
+======================
+
+This document describes the commands and functions available to
+operators in the charybdis ircd, as used on
+`AthemeNet <http://www.atheme.net>`__.
+
+This document, and various ideas for features of charybdis, have been
+taken from dancer-ircd/hyperion, the ircd used on freenode, mainly
+written by Andrew Suffield and Jilles Tjoelker.
+
+While this document may be of some interest to the users of charybdis
+servers, it is intended as a reference for network staff.
+
+Charybdis is based on ircd-ratbox 2.1.4, although much has changed.
+`ircd-ratbox <http://www.ircd-ratbox.org>`__ is commonly used on efnet,
+and some other networks.

+Oper privileges
+===============
+
+These are specified in privset{}.
+
+oper:admin, server administrator
+--------------------------------
+
+Various privileges intended for server administrators. Among other
+things, this automatically sets umode +a and allows loading modules.
+
+oper:die, die and restart
+-------------------------
+
+This grants permission to use ``DIE`` and ``RESTART``, shutting down or
+restarting the server.
+
+oper:global\_kill, global kill
+------------------------------
+
+Allows using ``KILL`` on users on any server.
+
+oper:hidden, hide from /stats p
+-------------------------------
+
+This privilege currently does nothing, but was designed to hide bots
+from /stats p so users will not message them for help.
+
+oper:hidden\_admin, hidden administrator
+----------------------------------------
+
+This grants everything granted to the oper:admin privilege, except the
+ability to set umode +a. If both oper:admin and oper:hidden\_admin are
+possessed, umode +a can still not be used.
+
+oper:kline, kline and dline
+---------------------------
+
+Allows using ``KLINE`` and ``DLINE``, to ban users by user@host mask or IP
+address.
+
+oper:local\_kill, kill local users
+----------------------------------
+
+This grants permission to use ``KILL`` on users on the same server,
+disconnecting them from the network.
+
+oper:mass\_notice, global notices and wallops
+---------------------------------------------
+
+Allows using server name ($$mask) and hostname ($#mask) masks in ``NOTICE``
+and ``PRIVMSG`` to send a message to all matching users, and allows using
+the ``WALLOPS`` command to send a message to all users with umode +w set.
+
+oper:operwall, send/receive operwall
+------------------------------------
+
+Allows using the ``OPERWALL`` command and umode +z to send and receive
+operwalls.
+
+oper:rehash, rehash
+-------------------
+
+Allows using the ``REHASH`` command, to rehash various configuration files
+or clear certain lists.
+
+oper:remoteban, set remote bans
+-------------------------------
+
+This grants the ability to use the ON argument on ``DLINE``/``KLINE``/``XLINE``/``RESV``
+and ``UNDLINE``/``UNKLINE``/``UNXLINE``/``UNRESV`` to set and unset bans on other
+servers, and the server argument on ``REHASH``. This is only allowed if the
+oper may perform the action locally, and if the remote server has a
+shared{} block.
+
+.. note:: If a cluster{} block is present, bans are sent remotely even
+          if the oper does not have oper:remoteban privilege.
+
+oper:resv, channel control
+--------------------------
+
+This allows using /resv, /unresv and changing the channel modes +L and
++P.
+
+oper:routing, remote routing
+----------------------------
+
+This allows using the third argument of the ``CONNECT`` command, to instruct
+another server to connect somewhere, and using ``SQUIT`` with an argument
+that is not locally connected. (In both cases all opers with +w set will
+be notified.)
+
+oper:spy, use operspy
+---------------------
+
+This allows using ``/mode !#channel``, ``/whois !nick``, ``/who !#channel``,
+``/chantrace !#channel``, ``/topic !#channel``, ``/who !mask``, ``/masktrace
+!user@host :gecos`` and ``/scan umodes +modes-modes global list`` to see
+through secret channels, invisible users, etc.
+
+All operspy usage is broadcasted to opers with snomask ``+Z`` set (on the
+entire network) and optionally logged. If you grant this to anyone, it
+is a good idea to establish concrete policies describing what it is to
+be used for, and what not.
+
+If ``operspy_dont_care_user_info`` is enabled, ``/who mask`` is operspy
+also, and ``/who !mask``, ``/who mask``, ``/masktrace !user@host :gecos`` and ``/scan
+umodes +modes-modes global list`` do not generate ``+Z`` notices or logs.
+
+oper:unkline, unkline and undline
+---------------------------------
+
+Allows using ``UNKLINE`` and ``UNDLINE``.
+
+oper:xline, xline and unxline
+-----------------------------
+
+Allows using ``XLINE`` and ``UNXLINE``, to ban/unban users by realname.
+
+snomask:nick\_changes, see nick changes
+---------------------------------------
+
+Allows using snomask ``+n`` to see local client nick changes. This is
+designed for monitor bots.

+User Commands
+=============
+
+Standard IRC commands are not listed here. Several of the commands in
+the operator commands chapter can also be used by normal users.
+
+ACCEPT
+------
+
+::
+
+   ACCEPT nick, -nick, ...
+
+Adds or removes users from your accept list for umode +g and +R. Users
+are automatically removed when they quit, split or change nick.
+
+::
+
+   ACCEPT *
+
+Lists all users on your accept list.
+
+Support of this command is indicated by the ``CALLERID`` token in
+``RPL_ISUPPORT`` (005); the optional parameter indicates the letter of the
+“only allow accept users to send private messages” umode, otherwise +g.
+In charybdis this is always +g.
+
+CNOTICE
+-------
+
+::
+
+   CNOTICE nick channel :text
+
+Providing you are opped (+o) or voiced (+v) in channel, and nick is a
+member of channel, ``CNOTICE`` generates a ``NOTICE`` towards nick.
+
+``CNOTICE`` bypasses any anti-spam measures in place. If you get “Targets
+changing too fast, message dropped”, you should probably use this
+command, for example sending a notice to every user joining a certain
+channel.
+
+As of charybdis 3.1, ``NOTICE`` automatically behaves as ``CNOTICE`` if you are
+in a channel fulfilling the conditions.
+
+Support of this command is indicated by the ``CNOTICE`` token in
+``RPL_ISUPPORT`` (005).
+
+CPRIVMSG
+--------
+
+::
+
+   CPRIVMSG nick channel :text
+
+Providing you are opped (+o) or voiced (+v) in channel, and nick is a
+member of channel, ``CPRIVMSG`` generates a ``PRIVMSG`` towards nick.
+
+``CPRIVMSG`` bypasses any anti-spam measures in place. If you get “Targets
+changing too fast, message dropped”, you should probably use this
+command.
+
+As of charybdis 3.1, ``PRIVMSG`` automatically behaves as ``CPRIVMSG`` if you
+are in a channel fulfilling the conditions.
+
+Support of this command is indicated by the ``CPRIVMSG`` token in
+``RPL_ISUPPORT`` (005).
+
+FINDFORWARDS
+------------
+
+::
+
+   FINDFORWARDS channel
+
+.. note:: This command is only available if the ``m_findforwards.so``
+          extension is loaded.
+
+Displays which channels forward to the given channel (via cmode +f). If
+there are very many channels the list will be truncated.
+
+You must be a channel operator on the channel or an IRC operator to use
+this command.
+
+HELP
+----
+
+::
+
+   HELP [topic]
+
+Displays help information. topic can be ``INDEX``, ``CREDITS``, ``UMODE``, ``CMODE``,
+``SNOMASK`` or a command name.
+
+There are separate help files for users and opers. Opers can use ``UHELP``
+to query the user help files.
+
+IDENTIFY
+--------
+
+::
+
+   IDENTIFY parameters...
+
+.. note:: This command is only available if the ``m_identify.so``
+          extension is loaded.
+
+Sends an identify command to either NickServ or ChanServ. If the first
+parameter starts with #, the command is sent to ChanServ, otherwise to
+NickServ. The word ``IDENTIFY``, a space and all parameters are concatenated
+and sent as a ``PRIVMSG`` to the service. If the service is not online or
+does not have umode +S set, no message will be sent.
+
+The exact syntax for this command depends on the services package in
+use.
+
+KNOCK
+-----
+
+::
+
+   KNOCK channel
+
+Requests an invite to the given channel. The channel must be locked
+somehow (+ikl), must not be +p and you may not be banned or quieted.
+Also, this command is rate limited.
+
+If successful, all channel operators will receive a 710 numeric. The
+recipient field of this numeric is the channel.
+
+Support of this command is indicated by the ``KNOCK`` token in ``RPL_ISUPPORT``
+(005).
+
+MONITOR
+-------
+
+Server side notify list. This list contains nicks. When a user connects,
+quits with a listed nick or changes to or from a listed nick, you will
+receive a 730 numeric if the nick went online and a 731 numeric if the
+nick went offline.
+
+Support of this command is indicated by the ``MONITOR`` token in
+``RPL_ISUPPORT`` (005); the parameter indicates the maximum number of
+nicknames you may have in your monitor list.
+
+You may only use this command once per second.
+
+More details can be found in ``doc/monitor.txt`` in the source
+distribution.
+
+::
+
+   MONITOR + nick, ...
+
+Adds nicks to your monitor list. You will receive 730 and 731 numerics
+for the nicks.
+
+::
+
+   MONITOR - nick, ...
+
+Removes nicks from your monitor list. No output is generated for this
+command.
+
+::
+
+   MONITOR C
+
+Clears your monitor list. No output is generated for this command.
+
+::
+
+   MONITOR L
+
+Lists all nicks on your monitor list, using 732 numerics and ending with
+a 733 numeric.
+
+::
+
+   MONITOR S
+
+Shows status for all nicks on your monitor list, using 730 and 731
+numerics.

+User modes
+==========
+
+``+a``, server administrator
+----------------------------
+
+This vanity usermode is used to denote a server administrator in WHOIS
+output. All local “admin” privileges are independent of it, though
+services packages may grant extra privileges to ``+a`` users.
+
+``+D``, deaf
+------------
+
+.. note:: This is a user umode, which anybody can set. It is not
+          specific to operators.
+
+Users with the ``+D`` umode set will not receive messages sent to channels.
+Joins, parts, topic changes, mode changes, etc are received as normal,
+as are private messages.
+
+Support of this umode is indicated by the ``DEAF`` token in ``RPL_ISUPPORT``
+(005); the parameter indicates the letter of the umode. Note that
+several common IRCD implementations have an umode like this (typically
+``+d``) but do not have the token in 005.
+
+``+g``, Caller ID
+-----------------
+
+.. note:: This is a user umode, which anybody can set. It is not
+    specific to operators.
+
+Users with the ``+g`` umode set will only receive private messages
+from users on a session-defined whitelist, defined by the ``/accept``
+command. If a user who is not on the whitelist attempts to send a
+private message, the target user will receive a rate-limited notice
+saying that the user wishes to speak to them.
+
+Network operators are not affected by the callerid whitelist system in
+the event that they need to speak to users who have it enabled.
+
+Support of this umode is indicated by the ``CALLERID`` token in
+``RPL_ISUPPORT`` (005); the optional parameter indicates the letter of
+the umode, otherwise ``+g``.
+
+``+i``, invisible
+-----------------
+
+.. note:: This is a user umode, which anybody can set. It is not
+          specific to operators.
+
+Invisible users do not show up in ``WHO`` and ``NAMES`` unless you can see them.
+
+``+l``, receive locops
+----------------------
+
+``LOCOPS`` is a version of ``OPERWALL`` that is sent to opers on a single server
+only. With cluster{} and shared{} blocks they can optionally be
+propagated further.
+
+Unlike ``OPERWALL``, any oper can send and receive ``LOCOPS``.
+
+``+o``, operator
+----------------
+
+This indicates global operator status.
+
+``+Q``, disable forwarding
+--------------------------
+
+.. note:: This is a user umode, which anybody can set. It is not
+          specific to operators.
+
+This umode prevents you from being affected by channel forwarding. If
+enabled on a channel, channel forwarding sends you to another channel if
+you could not join. See channel mode ``+f`` for more information.
+
+``+R``, reject messages from unauthenticated users
+--------------------------------------------------
+
+.. note:: This is a user umode, which anybody can set. It is not
+          specific to operators.
+
+If a user has the ``+R`` umode set, then any users who are not authenticated
+will receive an error message if they attempt to send a private message
+or notice to the ``+R`` user.
+
+Opers and accepted users (like in ``+g``) are exempt. Unlike ``+g``, the target
+user is not notified of failed messages.
+
+``+s``, receive server notices
+------------------------------
+
+This umode allows an oper to receive server notices. The requested types
+of server notices are specified as a parameter (“snomask”) to this
+umode.
+
+``+S``, network service
+-----------------------
+
+.. note:: This umode can only be set by servers named in a service{}
+          block.
+
+This umode grants various features useful for services. For example,
+clients with this umode cannot be kicked or deopped on channels, can
+send to any channel, do not show channels in ``WHOIS``, can be the target of
+services aliases and do not appear in ``/stats p``. No server notices are
+sent for hostname changes by services clients; server notices about
+kills are sent to snomask ``+k`` instead of ``+s``.
+
+The exact effects of this umode are variable; no user or oper on an
+actual charybdis server can set it.
+
+``+w``, receive wallops
+-----------------------
+
+.. note:: This is a user umode, which anybody can set. It is not
+          specific to operators.
+
+Users with the ``+w`` umode set will receive ``WALLOPS`` messages sent by opers.
+Opers with ``+w`` additionally receive ``WALLOPS`` sent by servers (e.g. remote
+``CONNECT``, remote ``SQUIT``, various severe misconfigurations, many services
+packages).
+
+``+z``, receive operwall
+------------------------
+
+``OPERWALL`` differs from ``WALLOPS`` in that the ability to receive such
+messages is restricted. Opers with ``+z`` set will receive ``OPERWALL``
+messages.
+
+``+Z``, SSL user
+----------------
+
+This umode is set on clients connected via SSL/TLS. It cannot be set or
+unset after initial connection.
+
+Snomask usage
+=============
+
+Usage is as follows::
+
+  MODE nick +s +/-flags
+
+To set snomasks.
+
+::
+
+   MODE nick -s
+
+To clear all snomasks.
+
+Umode ``+s`` will be set if at least one snomask is set.
+
+Umode ``+s`` is oper only by default, but even if you allow nonopers to set
+it, they will not get any server notices.
+
+Meanings of server notice masks
+===============================
+
+``+b``, bot warnings
+--------------------
+
+Opers with the ``+b`` snomask set will receive warning messages from the
+server when potential flooders and spambots are detected.
+
+``+c``, client connections
+--------------------------
+
+Opers who have the ``+c`` snomask set will receive server notices when
+clients attach to the local server.
+
+``+C``, extended client connection notices
+------------------------------------------
+
+Opers who have the ``+C`` snomask set will receive server notices when
+clients attach to the local server. Unlike the ``+c`` snomask, the
+information is displayed in a format intended to be parsed by scripts,
+and includes the two unused fields of the ``USER`` command.
+
+``+d``, debug
+-------------
+
+The ``+d`` snomask provides opers extra information which may be of interest
+to debuggers. It will also cause the user to receive server notices if
+certain assertions fail inside the server. Its precise meaning is
+variable. Do not depend on the effects of this snomask as they can and
+will change without notice in later revisions.
+
+``+f``, full warning
+--------------------
+
+Opers with the ``+f`` snomask set will receive notices when a user
+connection is denied because a connection limit is exceeded (one of the
+limits in a class{} block, or the total per-server limit settable with
+``/quote set max``).
+
+``+F``, far client connection notices
+-------------------------------------
+
+.. note:: This snomask is only available if the ``sno_farconnect.so``
+          extension is loaded.
+
+Opers with ``+F`` receive server notices when clients connect or disconnect
+on other servers. The notices have the same format as those from the ``+c``
+snomask, except that the class is ? and the source server of the notice
+is the server the user is/was on.
+
+No notices are generated for netsplits and netjoins. Hence, these
+notices cannot be used to keep track of all clients on the network.
+
+There is no far equivalent of the ``+C`` snomask.
+
+``+k``, server kill notices
+---------------------------
+
+Opers with the ``+k`` snomask set will receive server notices when services
+kill users and when other servers kill and save (forced nick change to
+UID) users. Kills and saves by this server are on ``+d`` or ``+s``.
+
+``+n``, nick change notices
+---------------------------
+
+An oper with ``+n`` set will receive a server notice every time a local user
+changes their nick, giving the old and new nicks. This is mostly useful
+for bots that track all users on a single server.
+
+``+r``, notices on name rejections
+----------------------------------
+
+Opers with this snomask set will receive a server notice when somebody
+tries to use an invalid username, or if a dumb HTTP proxy tries to
+connect.
+
+``+s``, generic server notices
+------------------------------
+
+This snomask allows an oper to receive generic server notices. This
+includes kills from opers (except services).
+
+``+u``, unauthorized connections
+--------------------------------
+
+This snomask allows an oper to see when users try to connect who do not
+have an available auth{} block.
+
+``+W``, whois notifications
+---------------------------
+
+.. note:: This snomask is only available if the ``sno_whois.so``
+          extension is loaded.
+
+Opers with ``+W`` receive notices when a ``WHOIS`` is executed on them on their
+server (showing idle time).
+
+``+x``, extra routing notices
+-----------------------------
+
+Opers who have the ``+x`` snomask set will get notices about servers
+connecting and disconnecting on the whole network. This includes all
+servers connected behind the affected link. This can get rather noisy
+but is useful for keeping track of all linked servers.
+
+``+y``, spy
+-----------
+
+Opers with ``+y`` receive notices when users try to join ``RESV``'ed (“juped”)
+channels. Additionally, if certain extension modules are loaded, they
+will receive notices when special commands are used.
+
+``+Z``, operspy notices
+-----------------------
+
+Opers with ``+Z`` receive notices whenever an oper anywhere on the network
+uses operspy.
+
+This snomask can be configured to be only effective for admins.

-      <sect2>
-	<title>+b, channel ban</title>
-	<para>
-	  Bans take one parameter which can take several forms.
-	  The most common form is +b nick!user@host.
-	  The wildcards * and ? are allowed, matching zero-or-more, and
-	  exactly-one characters respectively. The masks will be trimmed to fit the maximum allowable
-	  length for the relevant element.
-	  Bans are also checked against the IP address, even if it resolved or
-	  is spoofed.
-	  CIDR is supported, like *!*@10.0.0.0/8. This is most useful with
-	  IPv6.
-	  Bans are not checked against the real hostname behind any kind
-	  of spoof, except if host mangling is in use (e.g.
-	  <filename>extensions/ip_cloaking.so</filename>):
-	  if the user's host is mangled, their real hostname is checked
-	  additionally, and if a user has no spoof but could enable mangling,
-	  the mangled form of their hostname is checked additionally.
-	  Hence, it is not possible to evade bans by toggling
-	  host mangling.
-	</para>
-	<para>
-	  The second form (extban) is +b $type or +b $type:data. 
-	  type is a single character (case insensitive) indicating the
-	  type of match, optionally preceded by a tilde (~) to negate the
-	  comparison. data depends on type. Each type is loaded as a module.
-	  The available types (if any)
-	  are listed in the EXTBAN token of the 005 (RPL_ISUPPORT) numeric.
-	  See <filename>doc/extban.txt</filename> in the source distribution
-	  for more information.
-	</para>
-	<para>
-	  If no parameter is given, the list of bans is returned. All users
-	  can use this form. The plus sign should also be omitted.
-	</para>
-	<para>
-	  Matching users will not be allowed to join the channel or knock
-	  on it. If they are already on the channel, they may not send to
-	  it or change their nick.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+c, colour filter</title>
-	<para>
-	  This cmode activates the colour filter for the channel. This filters out bold, underline,
-	  reverse video, beeps, mIRC colour codes, and ANSI escapes. Note that escape sequences will
-	  usually leave cruft sent to the channel, just without the escape characters themselves.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+e, ban exemption</title>
-	<para>
-	  This mode takes one parameter of the same form as bans, which
-	  overrides +b and +q bans for all clients it matches.
-	</para>
-	<para>
-	  This can be useful if it is necessary to ban an entire ISP
-	  due to persistent abuse, but some users from that ISP should
-	  still be allowed in. For example:
-	  /mode #channel +be *!*@*.example.com *!*someuser@host3.example.com
-	</para>
-	<para>
-	  Only channel operators can see +e changes or request the list.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+f, channel forwarding</title>
-	<para>
-	  This mode takes one parameter, the name of a channel (+f #channel). If the channel also has the
-	  +i cmode set, and somebody attempts to join without either being expliticly invited, or having
-	  an invex (+I), then they will instead join the channel named in the mode parameter. The client
-	  will also be sent a 470 numeric giving the original and target channels.
-	</para>
-        <para>
-          Users are similarly forwarded if the +j cmode is set and their attempt to join is throttled,
-	  if +l is set and there are already too many users in the channel
-	  or if +r is set and they are not identified.
-        </para>
-        <para>
-          Forwards may only be set to +F channels, or to channels the setter
-          has ops in.
-        </para>
-	<para>
-	  Without parameter (/mode #channel f or /mode #channel +f) the
-	  forward channel is returned. This form also works off channel.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+F, allow anybody to forward to this</title>
-	<para>
-	  When this mode is set, anybody may set a forward from a channel
-	  they have ops in to this channel. Otherwise they have to have ops
-	  in this channel.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+g, allow anybody to invite</title>
-	<para>
-	  When this mode is set, anybody may use the INVITE command on the channel in question. When it
-	  is unset, only channel operators may use the INVITE command.
-	</para>
-	<para>
-	  When this mode is set together with +i, +j, +l or +r, all channel members can influence who can join.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+i, invite only</title>
-	<para>

-      </sect2>
-      <sect2>
-	<title>+I, invite exception (invex)</title>
-	<para>
-	  This mode takes one parameter of the same form as bans. Matching
-	  clients do not need to be invited to join the channel when it is invite-only (+i).
-	  Unlike the INVITE command, this does not override +j, +l and +r.
-	</para>
-	<para>
-	  Only channel operators can see +I changes or request the list.

-      <sect2>
-        <title>+j, join throttling</title>
-        <para>
-          This mode takes one parameter of the form <replaceable>n</replaceable>:<replaceable>t</replaceable>, where <replaceable>n</replaceable> and <replaceable>t</replaceable> are positive integers. Only <replaceable>n</replaceable> users may join in each period of <replaceable>t</replaceable> seconds.
-        </para>
-	<para>
-	  Invited users can join regardless of +j, but are counted as normal.

-	<para>
-	  Due to propagation delays between servers, more users may be

-      </sect2>
-      <sect2>
-	<title>+k, key (channel password)</title>

-      <sect2>
-	<title>+l, channel member limit</title>

-      </sect2>
-      <sect2>
-	<title>+L, large ban list</title>
-	<para>
-	  Channels with this mode will be allowed larger banlists (by default,
-          500 instead of 50 entries for +b, +q, +e and +I together).
-	  Only network operators with resv privilege may set this mode.
-	</para>

-	</para>
-      </sect2>
-      <sect2>
-	<title>+n, no external messages</title>
-	<para>
-	  When set, this mode prevents users from sending to the channel without being in it themselves.
-	  This is recommended.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+o, channel operator</title>
-	<para>
-	  This mode takes one parameter, a nick, and grants or removes channel
-	  operator privilege to that user. Channel operators have full control
-	  over the channel, having the ability to set all channel modes except
-	  +L and +P, and kick users.
-	  Like voiced users, channel operators can always
-	  send to the channel, overriding +b, +m and +q modes and the
-	  per-channel flood limit.
-	  In most clients channel operators are marked with an '@' sign.
-	</para>
-	<para>
-	  The privilege is lost if the user leaves the channel or server
-	  in any way.
-	</para>
-	<para>
-	  Most networks will run channel registration services (e.g. ChanServ)
-	  which ensure the founder (and users designated by the founder) can
-	  always gain channel operator privileges and provide some features
-	  to manage the channel.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+p, paranoid channel</title>
-	<para>
-	  When set, the KNOCK command cannot be used on the channel
-	  to request an invite, and users will not be shown the
-	  channel in WHOIS replies unless they are on it.
-	  Unlike in traditional IRC, +p and +s can be set together.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+P, permanent channel</title>
-	<para>
-	  Channels with this mode (which is accessible only to network operators with resv privilege) set will not be destroyed
-	  when the last user leaves.
-	</para>
-	<para>
-	  This makes it less likely modes, bans and the topic will be lost and
-	  makes it harder to abuse network splits, but also causes more
-	  unwanted restoring of old modes, bans and topics after long splits.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+q, quiet</title>
-	<para>
-	  This mode behaves exactly like +b (ban), except that the user may still join
-	  the channel. The net effect is that they cannot knock on the channel,
-	  send to the channel or change their nick while on channel.
-	</para>
-      </sect2>
-      <sect2>
-        <title>+Q, block forwarded users</title>
-        <para>
-          Channels with this mode set are not valid targets for forwarding. Any attempt to forward to
-          this channel will be ignored, and the user will be handled as if the attempt was never made (by
-          sending them the relevant error message).
-        </para>
-        <para>
-          This does not affect the ability to set +f.
-        </para>
-      </sect2>
-      <sect2>
-        <title>+r, block unidentified</title>
-        <para>
-          When set, this mode prevents unidentified users from joining.
-	  Invited users can still join.

-        <title>+R, quiet unidentified</title>
-        <para>
-          When set, this mode prevents unidentified users from sending to the channel, although they can
-          still join.
-        </para>
-	<para>
-	  Please note that this mode is not implemented in Charybdis 1.0.x, and is documented in
-	  expectation for upcoming Charybdis 1.1.
-	</para>
-      </sect2>
-      -->
-      <sect2>
-	<title>+s, secret channel</title>
-	<para>
-	  When set, this mode prevents the channel from appearing in the
-	  output of the LIST, WHO and WHOIS command by users who are not on
-	  it. Also, the server will refuse to answer WHO, NAMES, TOPIC and
-	  LIST queries from users not on the channel.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+t, topic limit</title>
-	<para>
-	  When set, this mode prevents users who are not channel operators
-	  from changing the topic.
-	</para>
-      </sect2>
-      <sect2>
-	<title>+v, voice</title>
-	<para>
-	  This mode takes one parameter, a nick, and grants or removes voice
-	  privilege to that user. Voiced users can always send to the channel,
-	  overriding +b, +m and +q modes and the per-channel flood limit.
-	  In most clients voiced users are marked with a plus sign.
-	</para>
-	<para>
-	  The privilege is lost if the user leaves the channel or server
-	  in any way.
-	</para>
-      </sect2>
-      <sect2>
-        <title>+z, reduced moderation</title>
-        <para>
-          When +z is set, the effects of +m, +b and +q are relaxed. For each message, if that message
-          would normally be blocked by one of these modes, it is instead sent to all channel operators. This is intended for use in moderated debates.
-        </para>
-        <para>
-          Note that +n is unaffected by this. To silence a given user completely,
-	  remove them from the channel.

+ * ARM mbedTLS required a CA certificate to be set in its configuration before it will
+ * process a client certificate from peers. Since we want to do that, and not all
+ * installations will have a CA certificate to hand, we have this.
+ *
+ * Its key was securely destroyed after being generated, but even if it wasn't, that
+ * doesn't matter; the IRCd will accept ALL certificates, whether signed by this CA
+ * certificate or not!
+ *
+ * After all, it only cares about certificates in as far as to generate a fingerprint
+ * for them.
+ *
+ * Yes, this is a massive hack, but there is no alternative for older versions.
+ *
+ * This issue was fixed in commit 39ae8cd2077d on the MbedTLS 2.5 development branch,
+ * released in version 2.5.1 on 19 June 2017. This certificate will not be used if
+ * that version (or greater) is installed.

+/*
+ * A long time ago, in a world far away, OpenSSL had a well-established mechanism for ensuring compatibility with
+ * regards to added, changed, and removed functions, by having an SSLEAY_VERSION_NUMBER macro. This was then
+ * renamed to OPENSSL_VERSION_NUMBER, but the old macro was kept around for compatibility until OpenSSL version
+ * 1.1.0.
+ *
+ * Then the OpenBSD developers decided that having OpenSSL in their codebase was a bad idea. They forked it to
+ * create LibreSSL, gutted all of the functionality they didn't want or need, and generally improved the library
+ * a lot. Then, as the OpenBSD developers are want to do, they packaged up LibreSSL for release to other
+ * operating systems, as LibreSSL Portable. Think along the lines of OpenSSH where they have also done this.
+ *
+ * The fun part of this story ends there. LibreSSL has an OPENSSL_VERSION_NUMBER macro, but they have set it to a
+ * stupidly high value, version 2.0. OpenSSL version 2.0 does not exist, and LibreSSL 2.2 does not implement
+ * everything OpenSSL 1.0.2 or 1.1.0 do. This completely breaks the entire purpose of the macro.
+ *
+ * The ifdef soup below is for LibreSSL compatibility. Please find whoever thought setting OPENSSL_VERSION_NUMBER
+ * to a version that does not exist was a good idea. Encourage them to realise that it is not.   -- amdj
