charybdis-3.5.0

server protocol

  • Fix propagation of ip_cloaking hostname changes (only when setting or unsetting the umode after connection).
  • Fix a remote-triggerable crash triggered by the CAPAB parsing code.
  • As per the TS6 spec, require QS and ENCAP capabilities.
  • Require EX and IE capabilities (+e and +I cmodes).
  • Check that UIDs start with the server's SID.

user

  • Allow mode queries on mlocked modes. In particular, allow /mode #channel f to query the forward channel even if +f is mlocked.
  • Strip colours from channel topics in /list.
  • If umode +D or +g are oper-only, don't advertise them in 005.
  • If MONITOR is not enabled, don't advertise it in 005.
  • Add starttls as per ircv3.
  • Abort a whowas listing when it would exceed SendQ, which would previously disconnect the user.
  • Reject nicks with '' in them, rather than truncating at the ''.
  • Remove CHARSET=ascii from ISUPPORT
  • Use the normal rules for IP visibility in /whowas.
  • Cmode +c now strips '\x0F' (^O, formatting off), fixing weird rendering in some clients that internally use mIRC formatting such as highlighted messages in HexChat.

  • Do not allow SASL authentication when the configured SASL agent is unavailable.
  • Automatically add unidentified users to the ACCEPT list when a user is set +R, as we do when the user is set +g.
  • Implement IRCv3.2 capabilities:
    • cap-notify
    • chghost
    • userhost-in-names
  • Implement the $&, $| and $m extban types:
    • $& combines 1 or more child extbans as an AND expression
    • $| combines 1 or more child extbans as an OR expression
    • $m provides normal hostmask matching as an extban for the above
  • Do not allow STARTTLS if a connection is already using TLS.
  • Display an operator's privilege set in WHOIS.
  • The $o extban now matches against privilege set names as well as individual privileges. Privilege set names are preferred over individual privileges.

oper

  • Turn off umode +p (override) when deopering.
  • Make listener error messages (e.g. port already in use) visible by default instead of only on snomask +d and in ioerrorlog.
  • Remove snotes on +r about GET/PUT/POST commands ("HTTP Proxy disconnected").
  • Add DNSBL snotes on snomask +r.

config

  • Add hide_uncommon_channels extension to hide uncommon channel memberships in WHOIS, like in ircd-seven.
  • Add chm_nonotice extension, cmode +T to reject notices.
  • Add restrict-unauthenticated extension, prevents unauthenticated users from doing anything as channel operator.
  • Add no_kill_services extension, prevents local opers from killing services.
  • Allow matching specific replies of DNSBLs, using the new matches option.
  • Remove blowfish crypt since it has the BSD advertising clause.
  • Fix SHA256 ($5$) crypt.
  • Make the channel::channel_target_change option actually work (it used to be always on).

misc

  • Work around timerfd/signalfd brokenness on OpenVZ.
  • Fix a compilation issue in libratbox/src/sigio.c with recent glibc.

  • Improve error messages about the configuration file.
  • Fix a crash when compiled with recent clang on 32-bit systems.
  • Fix various memory leaks in rehash.
  • Fix various code quality issues.
  • Add --with-shared-sqlite to allow distribution packages to link to a shared sqlite library. Using this is not recommended for on-server compilation.
  • ISUPPORT tokens which are actually provided by modules have been moved to their respective modules.

charybdis-3.4.0

server protocol

  • Allow overriding opers (with the new extension) to op themselves on channels.
  • Allow RSFNC to change a nickname's capitalization only.
  • Add channel ban forwarding $ much like ircd-seven. Local use of this is controlled by the channel::use_forward config option.
  • Add ENCAP TGINFO to propagate IP addresses that exceeded target change limits (these get a lower limit when they reconnect).

user

  • Consider bogus CTCP ACTION messages (without action text) CTCP (for cmode +C).
  • Send ERR_TOOMANYCHANNELS for each channel join that fails due to channel limits.
  • Add account-notify client capability to notify clients about logins and logouts of users in common channels. See doc/account-notify.txt.
  • Add extended-join client capability to add account name and ircname to JOIN.
  • Add topic TS and channel TS constraints for /LIST (T<, T>, C<, C> parameters as in some other servers).
  • Disallow wildcarded nicknames in "hunted" parameters like /stats and /motd.
  • Disallow mIRC italics in channel names when disable_fake_channels.
  • Add AUTHENTICATE EXTERNAL support, allows SASL authentication using a certificate fingerprint.
  • Allow channel::kick_on_split_riding to protect channels with mlocked keys.
  • The NICKLEN token in 005 now only specifies the maximum usable nick length. The MAXNICKLEN token specifies the maximum nick length any user can have.
  • Disallow $ in usernames as this may cause problems with ban forwarding.
  • Add an error message (numeric 743) if a ban mask is invalid.
  • Extract the underlying IPv4 address from 6to4 and Teredo IPv6 addresses. Show it in a remote /whois and check channel bans, quiets, D:lines and K:lines against it. Note that ban exceptions and auth{} blocks are not checked.
  • Allow normal users to perform /privs on themselves, showing some privileges from the auth{} block.
  • Add away-notify client capability, see doc/away-notify.txt.
  • Add rate limit for high-bandwidth commands, in particular /who .
  • Rate limit /away to help avoid flooding via away-notify.
  • Apply colour stripping (cmode +c) and CTCP checking (cmode +C) to messages to @/+ channel as well.
  • Channel mode +c (and other places that disallow colour codes) now also strip ASCII 4 (a different kind of colour code).

oper

  • Add operspy for /list.
  • Add a server notice to snomask +b if a user exceeds target change limits.
  • Add missing server notice for kills from RSFNC and SVSLOGIN.
  • Add /stats C to show information about dynamically loaded server capabilities.

config

  • Add support for linking using SSL certificate fingerprints as the link credential rather than the traditional password pair.
  • Add m_roleplay extension, provides various roleplay commands.
  • Add override extension, umode +p oper override for opers with oper:override permission, with accountability notices and timeout. Note that opers cannot op themselves if there are older servers on the network.
  • Add channel::disable_local_channels config option.
  • Add support for IPv6 DNSBLs. A new "type" option specifies the IP version(s) for which each DNSBL should be checked.
  • Make flood control settings configurable by those who know exactly what they are doing.
  • Add serverinfo::nicklen config option to limit the nick length for local users. Different values of this option do not break the server protocol.
  • Add extb_usermode extension, $m:+- extban matching against umodes.
  • Extend extb_oper extension to allow matching against oper privileges.
  • Add m_remove extension, /remove command as in ircd-seven.
  • Add general::away_interval to allow configuring /away rate limiting.
  • Add listener::defer_accept to delay accepting a connection until the client sends data. This depends on kernel support. It may break BOPM checking.

misc

  • In mkpasswd, default to SHA512-based crypt instead of MD5-based crypt.
  • Add --with-custom-branding and --with-custom-version configure options to help forks/patchsets distinguish themselves.
  • Change version control from Mercurial to GIT.
  • Ensure SIGHUP and SIGINT keep working after a SIGINT restart.
  • Add --enable-fhs-paths configure option to allow installing into a more FHS-like hierarchy.
  • Remove broken GnuTLS support. SSL/TLS is now only provided using OpenSSL.

charybdis-3.3.0

server protocol

  • Add new BAN command, for propagated network-wide bans (K/X:lines and RESVs). These will burst to new servers as they are introduced, and will stay in sync across the whole network (new BAN capab).
  • Add new MLOCK command, to implement ircd-side channel mode locks. This allows services to send out a list of mode letters for a given channel which may not be changed, preventing mode fights between services and client bots (new MLOCK capab).

user

  • New RPL_QUIETLIST(728) and RPL_ENDOFQUIETLIST(729) numerics are used for the quiet (+q) list, instead of overloading the ban list numerics.
  • Users may no longer change the topic of a -t channel if they cannot send to it.
  • Add help for EXTBAN, describing the syntax of extended bans in general, as well as the most common types.
  • Changed AWAY messages are now propagated to other servers. Previously, AWAY was only propagated when the user was not already away.
  • Channel mode +c (and other places that disallow colour codes) now also strip ASCII 29 (mIRC 7 italics).
  • Add auto-accept for user mode +g (callerid): Messaging a user while set +g will automatically add them to your accept list.
  • Add target change for channels. It applies to unopped, unvoiced and unopered users. This has the effect of stopping spambots which join, message and part many channels at a time.
  • Show RPL_WHOISLOGGEDIN in /whowas as well as in /whois entries. This adds at most an additional 0.5MB of memory usage.

config

  • Add general::use_propagated_bans to switch the new BAN system on or off.
  • Add general::default_ident_timeout, to control the timeout for identd (auth) connections.
  • Add channel::channel_target_change to switch the new channel target change limits on or off.
  • Fix class::number_per_ident so that it also applies to connections without identd.
  • Change the example sslport option to 6697, which is more standard than 9999.

misc

  • The custom channel mode API has been rewritten, allowing these modules to work correctly when reloaded, or loaded from the config file.
  • The EFNet RBL is now recommended, instead of DroneBL.
  • Remove the unsupported modules directory.
  • Numerous bug fixes and code cleanups.
  • In mkpasswd, default to MD5 crypt instead of insecure DES.

charybdis-3.2.0

server protocol

  • Apply +z to messages blocked by +b and +q as well. (new EOPMOD capab)
  • Add new topic command ETB, allowing services to set topic+setter+ts always. (new EOPMOD capab)
  • The slash ('/') character is now allowed in spoofs.

user

  • Add can_kick hook, based on the ircd-seven one.
  • Add cmode +C (no CTCP) from ircd-seven.
  • Flood checking has been reworked.
  • Fix op-moderate (cmode +z) for channel names with '@'.
  • Add CERTFP support, allowing users to connect with an SSL client certificate and propagating the certificate fingerprint to other servers. Services packages can use this to identify users based on client certificates.
  • Maintain the list of recently used targets (for the target change anti-spam system) in most-recently-used order, overwriting the least recently used target with a new one. This should be friendlier to users without giving spambots anything.
  • Do not require target change slots for replying to the last five users to send a private message, notice or invite.
  • Apply target change restrictions to /invite.
  • Apply umode +g/+R restrictions to /invite, with the difference that instead of sending " is messaging you" the invite is let through since that is just as noisy.

oper

  • Add /rehash throttles to clear throttling.
  • Send all server notices resulting from a remote /rehash to the oper.
  • '\s' for space is now part of the matching, not a substitution at xline time, fixing various issues with it.
  • Display o:line "nickname" in oper-up server notices.
  • Fix sendq exceeded snotes for servers.
  • SCAN UMODES: default list-max to 500, like a global WHO.
  • Ignore directory names in MODRELOAD to avoid crashing if it is a core module and the path is incorrect.
  • Tweaks to spambot checks.

config

  • Add channel::only_ascii_channels config option to restrict channel names to printable ascii only.
  • Add channel::resv_forcepart, forcibly parts local users on channel RESV, default enabled.

misc

  • New mkpasswd from ircd-ratbox.
  • Check more system calls for errors and handle the errors.
  • Various ssld/libratbox bugfixes from ircd-ratbox. [some MERGED]
  • Fix fd passing on FreeBSD/amd64 and possibly Solaris/sparc. [MERGED]
  • Various documentation improvements. [some MERGED]
  • Fix some crash issues. [MERGED]
  • Add bandb from ircd-ratbox, which stores permanent dlines/klines/xlines/resvs in an sqlite database instead of a flatfile and does the storage in a helper process. Use bin/bantool -i to import your old bans into the database.

charybdis-3.1.0

  • Remove TS5 support. No TS5 servers are permitted in a network with charybdis 3.1.0 or newer, except jupes.
  • Replace oper flags by privilege sets (privsets). This adds an extra level of indirection between oper flags and operator blocks. /stats O (capital O) shows the configured privsets.
  • Update libratbox and ssld from upstream and use it better.
  • Add auth_user to auth{}. This allows specifying a username:password instead of just a password in PASS, so that a fixed user@host is not necessary for a specific auth{} block.
  • Add need_ssl to auth{} and operator{}. This makes these blocks reject the user if not connected via SSL.
  • Allow modules to provide simple channel modes without parameter.
  • Remove restrictions on CNAME in the resolver.
  • Make the resolver remember nonresponsive nameservers.
  • Move nick collision notices from +s to +k.
  • Add additional information to various server notices about server connections.
  • Show throttle information in /stats t.
  • Show rejectcache and throttle information in /testline.
  • Show oper reason in /testline.
  • Allow opers to see other users' umodes with /mode .
  • SCAN UMODES GLOBAL NO-LIST MASK is no longer an operspy command.
  • Also apply floodcount to messages to remote clients (except services).
  • Remove user@server messages to local users. Sending such messages to remote servers is still possible, for securely messaging pseudoservers whether service{}'ed or not. The special oper-only syntax opers@server remains as well.
  • Allow /list on a named +p channel. A full /list already included +p channels.
  • Add operspy /topic.
  • For remote rehashes, send error messages to the requesting oper as well.
  • Disable autoconnect for a server with excessive TS delta.
  • Disallow invites to juped channels.
  • Warn about certain duplicate and redundant auth blocks.
  • Make PRIVMSG/NOTICE behave as CPRIVMSG/CNOTICE automatically if possible.
  • Allow +z messages from outside if a channel is -n.
  • Allow coloured part reasons in -c channels.
  • Add ircu-like WHOX support. This allows requesting specific information in /who and allows obtaining services login name for all users in a channel. XChat/Conspire use WHOX to update away status more efficiently.
  • Allow opers and shide_exempt users to see hopcounts even if flatten_links is on.
  • Rework ip_cloaking.
  • Add the IP address to userlog, as in ircd-ratbox 3.0.
  • Split cidr_bitlen into cidr_ipv4_bitlen and cidr_ipv6_bitlen.
  • Allow using ziplinks with SSL connections. This is not as efficient as using OpenSSL's built in compression, but also works with older versions of OpenSSL.
  • Fix an off by one error with zipstats processing, which could overwrite a variable with NULL causing a crash on some systems.
  • Document some extensions in charybdis-oper-guide.
  • Add more server protocol documentation.
  • Add m_sendbans extension, SENDBANS command to propagate xlines and resvs manually.
  • Add chm_sslonly extension, cmode +S for SSL/TLS only channels.
  • Add chm_operonly extension, cmode +O for IRCop only channels.
  • Add chm_adminonly extension, cmode +A for server admin only channels.
  • Various code cleanups.

charybdis-3.0.4

  • Fix a crash on certain recent versions of Ubuntu.

  • A new extban, $z, has been added for ssl users (extensions/extb_ssl.so).
  • A new compatibility channel mode, +R, has been added, it sets +q/-q $~a (extensions/chm_operonly_compat.so). This is similar to the +R seen in ircd-seven.
  • A new compatibility channel mode, +S, has been added, it sets +b/-b $~z (extensions/chm_sslonly_compat.so).
  • A new compatibility channel mode, +O, has been added, it sets +iI/-iI $o (extensions/chm_operonly_compat.so).
  • Add remote D:lines. Note that these are not enabled by default.
  • Remove EFnet-style G:lines. Noone appears to use these.
  • Remove idle time checking (auto disconnecting users idle too long).
  • Display a notice to clients when the IRCd is shut down using SIGTERM.
  • Some error messages have been clarified to enhance usability.

  • Add /privs command, shows effective privileges of a client.

charybdis-2.2.0

  • The I/O code has been reworked, file descriptor metadata is stored in a hashtable and the maximum number of clients can now be set in ircd.conf.
  • Improve error checking and error messages for kline/dline/xline/resv files.
  • Allow kline ipv6:address, unkline some.host and unkline ipv6:address without *@.
  • Add accountability (wallops, log) to OKICK extension.
  • Add opernick to OPME/OMODE/OJOIN log messages.
  • Add use_forward option, allows disabling cmode +fFQ and umode +Q.
  • Add keyword substitution to DNSBL reasons, making it possible to show things like the user's IP address in the reason.
  • Use sendto_one_notice() more.
  • Server notices about kills now include the victim's nick!user@host instead of just nick.
  • Include real hostname in Closing Link message for unknown connections that have sent USER, in particular banned users.
  • Add some documentation about the SASL client protocol.
  • Change spambot, flooder and jupe joiner notices from host to orighost.
  • Remove the last remains of server hostmasking (this made it possible to have multiple servers with similar names appear as a single server).
  • Keep bitmasks of modularized umodes reserved forever to the letter, avoiding problems when reloading umode modules in a different order.
  • Fix -logfile.
  • Update to the new revision (v8) of the TS6 spec, this fixes problems with joins reversing certain mode changes crossing them. This interoperates with older versions.
  • Put "End of Channel Quiet List" at the end of +q lists.
  • Fix invisible count getting desynched from reality if the act of opering up sets -i or +i.
  • Don't leak auth{} spoofed IP addresses in +f notices.
  • Shorten quit/part/kick reasons to avoid quit reasons overflowing the client exiting server notice (from TOPICLEN to 260).
  • Fix some cases where 10 char usernames lose their final character.
  • Move username check after xline and dnsbl checks, so it will not complain to opers about clients who are xlined or blacklisted anyway (both of which silently reject).
  • Remove invite_ops_only config option, forcing it to YES.
  • Allow /invite (but not invex) to override +r, +l, +j in addition to +i.
  • Add several new extensions, such as createoperonly.
  • Merge whois notice extensions into one and move it from snomask +y to +W.

charybdis-2.1.2

  • Fix bug that could cause all hostmangled users to be exempted when a single ban exception existed on a channel.
  • Tweak \s code a little.
  • Add a minor clarification to the SGML docs.
  • Avoid truncation in ip_cloaking (by removing components on the other side). Note that this may cause channel +bqeI modes set on such very long hosts to no longer match.

charybdis-2.1.1

  • Search the shortest list (user's/channel's) when looking up channel memberships.
  • Make the SID-collision notice look right under all conditions.
  • Move kills from services from +s to +k snomask.
  • When no_tilde is present on an auth{} block, check the non-tilde version of the user@host against k:lines as well.
  • Put full reason in the SQUIT reason when a server is rejected for insufficient parameters being passed to a command.
  • Don't redirect users to an existing domain, irc.fi.
  • Improve communication of servlink-related error messages.

charybdis-2.1.0

  • Allow +S clients (services) to send to channels and @/+ channels always.
  • Allow normal match() on IP address also in /masktrace.
  • Add new testmask from ratbox 2.2. Allows matches on nick, ip and gecos in addition to user and host, and is fully analogous to masktrace. The numeric has changed from 724 to 727 and fields in it have changed.
  • Show IP addresses to opers in /whowas.
  • Add extb_extgecos extban option ($x:nick!user@host#gecos), from sorcery modules.

  • Replace ADNS with a new smaller resolver from ircu and hybrid.
  • Make services shortcuts (/chanserv etc) configurable in ircd.conf.
  • Add extban: extensible +bqeI matching via modules. Syntax is $[:]. By default no modules are loaded.

  • Add OMODE command to extensions/ for easier oper mode hacking.
  • Add HURT system to extensions/; this shuns clients matching certain host/ip unless and until they identify to services. Mainly intended for SorceryNet.
  • Show SASL success and failure counts in /stats t.
  • Allow more frequent autoconnects to servers.
  • Messaging services by nickname no longer uses target change slots.
  • Only accept SASL from servers in a service{} block.
