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.
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.
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
several days until after the rehash for the crash to occur, or even
weeks/months on smaller networks (accidental triggering, that is).
* A `REHASH` with certain remote includes setups could cause a crash or
other weird and confusing problems such as complaining about unable
to open an ipv6-database or missing snomask configuration.
This only affected some people with remote includes, not all.
* Potential out-of-bounds write in sending code. In practice it seems
harmless on most servers but this cannot be 100% guaranteed.
* Unlikely triggered log message would log uninitialized stack data to the
log file or send it to ircops.
* Channel ops could not remove halfops from a user (`-h`).
* After using the `RESTART` command (not recommended) the new IRCd was
often no longer writing to log files.
* Fix compile problem if you choose to use cURL remote includes but don't
have cURL on the system and ask UnrealIRCd to compile cURL.
Enhancements:
* The default text log format on disk changed. It now includes the server
name where the event was generated. Without this, it was sometimes
difficult to trace problems, since previously it sometimes looked like
there was a problem on your server when it was actually another server
on the network.
* Old log format: `[DATE TIME] subsystem.EVENT_ID loglevel: ........`
* New log format: `[DATE TIME] servername subsystem.EVENT_ID loglevel: ........`
Changes:
* Any MOTD lines added by services via
[`SVSMOTD`](https://www.unrealircd.org/docs/MOTD_and_Rules#SVSMOTD)
are now shown at the end of the MOTD-on-connect (unless using a shortmotd).
Previously the lines were only shown if you manually ran the `MOTD` command.
Developers and protocol:
* `LIST C<xx` now means: filter on channels that are created less
than `xx` minutes ago. This is the opposite of what we had earlier.
`LIST T<xx` is now supported as well (topic changed in last xx minutes),
it was already advertised in ELIST but support was not enabled previously.
UnrealIRCd 6.0.2
-----------------
UnrealIRCd 6.0.2 comes with several nice feature enhancements along with
some fixes. It also includes a fix for a crash bug that can be triggered
by ordinary users.
Fixes:
* Fix crash that can be triggered by regular users if you have any `deny dcc`
blocks in the config or any spamfilters with the `d` (DCC) target.
NOTE: You don't *have* to upgrade to 6.0.2 to fix this, you can also
hot-patch this issue without restart, see the news announcement.
* Windows: fix crash with IPv6 clients (local or remote) due to GeoIP lookup
* Fix infinite hang on "Loading IRCd configuration" if DNS is not working.
For example if the 1st DNS server in `/etc/resolv.conf` is down or refusing
requests.
* Some `MODE` server-to-server commands were missing a timestamp at the end,
even though this is mandatory for modes coming from a server.
* The [channeldb](https://www.unrealircd.org/docs/Set_block#set::channeldb)
module now converts letter extbans to named extbans (eg `~a` to `~account`).
Previously it did not, which caused letter extbans to appear in the banlist.
Later on, when linking servers, this would cause duplicate entries to appear
as well, with both the old and new format. The extbans were still effective
though, so this is mostly a visual +b/+e/+I list issue.
* Some [Extended Server Bans](https://www.unrealircd.org/docs/Extended_server_bans)
were not working correctly for WEBIRC proxies. In particular, a server ban
or exempt (ELINE) on `~country:XX` was only checked against the WEBIRC proxy.
Enhancements:
* Support for [logging to a channel](https://www.unrealircd.org/docs/Log_block#Logging_to_a_channel).
Similar to snomasks but then for channels.
* Command line interface changes:
* The [CLI tool](https://www.unrealircd.org/docs/Command_Line_Interface) now
communicates to the running UnrealIRCd process via a UNIX socket to
send commands and retrieve output.
* The command `./unrealircd rehash` will now show the rehash output,
including warnings and errors, and return a proper exit code.
* The same for `./unrealircd reloadtls`
* New command `./unrealircd status` to show if UnrealIRCd is running, the
version, channel and user count, ..
* The command `./unrealircd genlinkblock` is now
[documented](https://www.unrealircd.org/docs/Linking_servers_(genlinkblock))
and is referred to from the
[Linking servers tutorial](https://www.unrealircd.org/docs/Tutorial:_Linking_servers).
* On Windows in the `C:\Program Files\UnrealIRCd 6\bin` directory there is
now an `unrealircdctl.exe` that can be used to do similar things to what
you can do on *NIX. Supported operations are: `rehash`, `reloadtls`,
`mkpasswd`, `gencloak` and `spkifp`.
* New option [set::server-notice-show-event](https://www.unrealircd.org/docs/Set_block#set::server-notice-show-event)
which can be set to `no` to hide the event information (eg `connect.LOCAL_CLIENT_CONNECT`)
in server notices. This can be overridden per-oper in the
[Oper block](https://www.unrealircd.org/docs/Oper_block) via oper::server-notice-show-event.
* Support for IRC over UNIX sockets (on the same machine), if you specify a
file in the [listen block](https://www.unrealircd.org/docs/Listen_block)
instead of an ip/port. This probably won't be used much, but the option is
there. Users will show up with a host of `localhost` and IP `127.0.0.1` to
keep things simple.
* The `MAP` command now shows percentages of users
* Add `WHO` option to search clients by time connected (eg. `WHO <300 t` to
search for less than 300 seconds)
* Rate limiting of `MODE nick -x` and `-t` via new `vhost-flood` option in
[set::anti-flood block](https://www.unrealircd.org/docs/Anti-flood_settings).
Changes:
* Update Russian `help.ru.conf`.
Developers and protocol:
* People packaging UnrealIRCd (eg. to an .rpm/.deb):
* Be sure to pass the new `--with-controlfile` configure option
* There is now an `unrealircdctl` tool that the `unrealircd` shell script
uses, it is expected to be in `bindir`.
* `SVSMODE #chan -b nick` will now correctly remove extbans that prevent `nick`
from joining. This fixes a bug where it would remove too much (for `~time`)
or not remove extbans (most other extbans, eg `~account`).
`SVSMODE #chan -b` has also been fixed accordingly (remove all bans
preventing joins).
Note that all these commands do not remove bans that do not affect joins,
such as `~quiet` or `~text`.
* For module coders: setting the `EXTBOPT_CHSVSMODE` flag in `extban.options`
is no longer useful, the flag is ignored. We now decide based on
`BANCHK_JOIN` being in `extban.is_banned_events` if the ban should be
removed or not upon SVS(2)MODE -b.
UnrealIRCd 6.0.1.1
===================
If you are already running UnrealIRCd 6 then read below on the
changes between 6.0.0 and 6.0.1(.1). Otherwise, jump straight to the
[summary about UnrealIRCd 6](#Summary) to learn more about UnrealIRCd 6.
-------------------
Fixes:
* In 6.0.1.1: extended bans were not properly synced between U5 and U6.
@ -89,6 +220,8 @@ Enhancements
* Colors are enabled by default in snomask server notices, these can be disabled via
[set::server-notice-colors](https://www.unrealircd.org/docs/Set_block#set::server-notice-colors)
and also in [oper::server-notice-colors](https://www.unrealircd.org/docs/Oper_block)
* Support for [logging to a channel](https://www.unrealircd.org/docs/Log_block#Logging_to_a_channel).
Similar to snomasks but then for channels. *Requires UnrealIRCd 6.0.2 or later*
* Almost all channel modes are modularized
* Only the three list modes (+b/+e/+I) are still in the core
* The five [level modes](https://www.unrealircd.org/docs/Channel_Modes#Access_levels)
