UnrealIRCd 6.0.3
=================
UnrealIRCd 6.0.4.2
===================
Another small update to 6.0.4.x:
A number of serious issues were discovered in UnrealIRCd 6. Among these is
an issue which will likely crash the IRCd sooner or later if you /REHASH
with any active clients connected.
We suggest everyone who is running UnrealIRCd 6 to upgrade to 6.0.3.
* Fix crash when linking. This requires a certain sequence of events: first
a server is linked in successfully, then we need to REHASH, and then a new
link attempt has to come in with the same server name (for example because
there is a network issue and the old link has not timed out yet).
If all that happens, then an UnreaIRCd 6 server may crash, but not always.
* Two IRCv3 specifications were ratified which we already supported as drafts:
* Change CAP `draft/extended-monitor` to `extended-monitor`
* Add message-tag `bot` next to existing (for now) `draft/bot`
* Update Turkish translations
UnrealIRCd 6.0.4.1
===================
This is a small update to 6.0.4. It fixes the following issues that were
present in all 6.0.x versions:
* Fix sporadic crash when linking a server (after successful authentication).
This feels like a compiler bug. It affected only some people with GCC and
only in some situations. When compiled with clang there was no problem.
Hopefully we can work around it this way.
* Make /INVITE bypass (nearly) all channel mode restrictions, as it used to
be in UnrealIRCd 5.x. Both for invites by channel ops and for OperOverride.
This also fixes a bug where an IRCOp with OperOverride could not bypass +l
(limit) and other restrictions and would have to resort back to using
MODE or SAMODE. Only +b and +i could be bypassed via INVITE OperOverride.
UnrealIRCd 6.0.4
-----------------
This release comes with lots of features and enhancements. In particular,
security groups and mask items now allow you to write cleaner and more
flexible configuration files. There are also JSON logging enhancements and
several bug fixes. Thanks a lot to everyone who tested the release candidates!
If you are already running UnrealIRCd 6 then read below. Otherwise, jump
straight to the [summary about UnrealIRCd 6](#Summary) to learn more
about UnrealIRCd 6.
### Enhancements:
* Show security groups in `WHOIS`
* The [security-group block](https://www.unrealircd.org/docs/Security-group_block)
has been expanded and the same functionality is now available in
[mask items](https://www.unrealircd.org/docs/Mask_item) too:
* This means the existing options like `identified`, `webirc`, `tls` and
`reputation-score` can be used in `allow::mask` etc.
* New options (in both security-group and mask) are:
* `connect-time`: time a user is connected to IRC
* `security-group`: to check another security group
* `account`: services account name
* `country`: country code, as found by GeoIP
* `realname`: realname (gecos) of the user
* `certfp`: certificate fingerprint
* Every option also has an exclude- variant, eg. `exclude-country`.
If a user matches any `exclude-` option then it is considered not a match.
* The modules [connthrottle](https://www.unrealircd.org/docs/Connthrottle),
[restrict-commands](https://www.unrealircd.org/docs/Set_block#set::restrict-commands)
and [antirandom](https://www.unrealircd.org/docs/Set_block#set::antirandom)
now use the new `except` sub-block which is a mask item. The old syntax
(eg <code>set::antirandom::except-webirc</code>) is still accepted by UnrealIRCd
and converted to the appropriate new setting behind the scenes
(<code>set::antirandom::except::webirc</code>).
* The modules [blacklist](https://www.unrealircd.org/docs/Blacklist_block)
and [antimixedutf8](https://www.unrealircd.org/docs/Set_block#set::antimixedutf8)
now also support the `except` block (a mask item).
* Other than that the extended functionality is available in these blocks:
`allow`, `oper`, `tld`, `vhost`, `deny channel`, `allow channel`.
* Example of direct use in a ::mask item:
```
/* Spanish MOTD for Spanish speaking countries */
tld {
mask { country { ES; AR; BO; CL; CO; CR; DO; EC; SV; GT; HN; MX; NI; PA; PY; PE; PR; UY; VE; } }
motd "motd.es.txt";
rules "rules.es.txt";
}
```
* Example of defining a security group and using it in a mask item later:
```
security-group irccloud {
mask { ip1; ip2; ip3; ip4; }
}
allow {
mask { security-group irccloud; }
class clients;
maxperip 128;
}
except ban {
mask { security-group irccloud; }
type { blacklist; connect-flood; handshake-data-flood; }
}
```
* Because the mask item is so powerful now, the `password` in the
[oper block](https://www.unrealircd.org/docs/Oper_block) is optional now.
* We now support oper::auto-login, which means the user will become IRCOp
automatically if they match the conditions on-connect. This can be used
in combination with
[certificate fingerprint](https://www.unrealircd.org/docs/Certificate_fingerprint)
authentication for example:
```
security-group Syzop { certfp "1234etc."; }
oper Syzop {
auto-login yes;
mask { security-group Syzop; }
operclass netadmin-with-override;
class opers;
}
except ban {
mask { security-group Syzop; }
type all;
}
```
* For [JSON logging](https://www.unrealircd.org/docs/JSON_logging) a number
of fields were added when a client is expanded:
* `geoip`: with subitem `country_code` (eg. `NL`)
* `tls`: with subitems `cipher` and `certfp`
* Under subitem `users`:
* `vhost`: if the visible host differs from the realhost then this is
set (thus for both vhost and cloaked host)
* `cloakedhost`: this is always set (except for eg. services users), even
if the user is not cloaked so you can easily search on a cloaked host.
* `idle_since`: last time the user has spoken (local clients only)
* `channels`: list of channels (array), with a maximum of 384 chars.
* The JSON logging now also strips ASCII below 32, so color- and
control codes.
* Support IRCv3 `+draft/channel-context`
* Add `example.es.conf` (Spanish example configuration file)
* The country of users is now communicated in the
[message-tag](https://www.unrealircd.org/docs/Message_tags)
`unrealircd.org/geoip` (only to IRCOps).
* Add support for linking servers via UNIX domain sockets
(`link::outgoing::file`).
### Fixes:
* Crash in `except ban` with `~security-group:xyz`
* Crash if hideserver module was loaded but `LINKS` was not blocked.
* Crash on Windows when using the "Rehash" GUI option.
* Infinite loop if one security-group referred to another.
* Duplicate entries in the `+beI` lists of `+P` channels.
* Regular users were able to -o a service bot (that has umode +S)
* Module manager did not stop on compile error
* [`set::modes-on-join`](https://www.unrealircd.org/docs/Set_block#set::modes-on-join)
did not work with `+f` + timed bans properly, eg `[3t#b1]:10`
* Several log messages were missing some information.
* Reputation syncing across servers had a small glitch. Fix is mostly
useful for servers that were not linked to the network for days or weeks.
### Changes:
* Clarified that UnrealIRCd is licensed as "GPLv2 or later"
* Fix use of variables in
[`set::reject-message](https://www.unrealircd.org/docs/Set_block#set::reject-message)
and in [`blacklist::reason](https://www.unrealircd.org/docs/Blacklist_block):
previously short forms of variables were (unintentionally) expanded
as well, such as `$serv` for `$server`. This is no longer supported, you need
to use the correct full variable names.
### Developers and protocol:
* The `creationtime` is now communicated of users. Until now this
information was only known locally (the thing that was communicated
that came close was "last nick change" but that is not the same).
This is synced via (early) moddata across servers.
Module coders can use `get_connected_time()`.
* The `RPL_HOSTHIDDEN` is now sent from `userhost_changed()` so you
don't explicitly send it yourself anymore.
* The `SVSO` command is back, so services can make people IRCOp again.
See `HELPOP SVSO` or [the commit](https://github.com/unrealircd/unrealircd/commit/50e5d91c798e7d07ca0c68d9fca302a6b6610786)
for more information.
* Due to last change the `HOOKTYPE_LOCAL_OPER` parameters were changed.
* Module coders can enhance the
[JSON logging](https://www.unrealircd.org/docs/JSON_logging)
expansion items for clients and channels via new hooks like
`HOOKTYPE_JSON_EXPAND_CLIENT`. This is used by the geoip and tls modules.
UnrealIRCd 6.0.3
-----------------
A number of serious issues were discovered in UnrealIRCd 6. Among these is
an issue which will likely crash the IRCd sooner or later if you /REHASH
with any active clients connected.
We suggest everyone who is running UnrealIRCd 6 to upgrade to 6.0.3.
Fixes:
* Crash in `WATCH` if the IRCd has been rehashed at least once. After doing
a `REHASH` with active clients it will likely corrupt memory. It may take
