snomasks, opers, global (remote), ..
For disk logs we currently ignore the sources and log everything.
NOTE: REHASH is untested and will memory leak for sure.
Note that without such a block nothing will be sent to ircops at all
(anything that comes from unreal_log anyway).
In a later commit either a snomasks.default.conf will be added and/or
an internal default mapping.
This also moves the recursion trap to earlier in the logging code,
which has the side effect that debug traffic regarding snomasks is
no longer logged.
for "unknown-users" and "known-users".
As a reminder, by default, "known-users" are users who are identified
to services OR are on an IP that has been connected for over 2 hours
in the past X days.
See https://www.unrealircd.org/docs/FAQ#new-anti-flood-block
for more information on the layout of the new block.
NOTE: This actual feature, the relase notes and the documentation
are all work in progress.
form an insecure connection. There we explain a bit on the why and how to
configure some random IRC clients.
This also silently adds support for multi-line messages in
set::plaintext-policy::user-message (for warn) and
set::plaintext-policy::oper-message (for warn and deny).
Remove old option set::ban-include-username and replace it with a more
generic option which defines what target a ban should apply to.
Also add some parts of set::manual-ban-target which will follow soon.
session after a 15 seconds timeout. The exact timeout value can be
changed by adjusting set::sasl-timeout, which should be (quite a bit)
less than set::handshake-timeout by the way. 15<30 now, so fine.
We actually have 3 possible settings of set::allowed-channelchars:
utf8: Channel must be valid UTF8, this is the new default
ascii: A very strict setting, for example in use at freenode,
the channel name may not contain high ascii or UTF8
any: A very loose setting, which allows almost all characters
in the channel name. This was the OLD default, up to and
including UnrealIRCd 4. It is no longer recommended.
For most networks this new default setting of utf8 will be fine, since
by far most IRC clients use UTF8 for many years already.
If you have a network that has a significant portion of chatters
that are on old non-UTF8 clients that use a specific character set
then you may want to use set { allowed-nickchars any; }
Some Russian and Ukrainian networks are known to need this.
Devs: src/utf8.c has been added which will be used by this and
by other functionality later.
aChannel to Channel, and some more. Third party module coders will
love this. But.. it makes things more logical and the doxygen output
will look more clean and logical as well.
(More changes will follow)
This determines when UnrealIRCd will use broadcast instead of multicast
for delivering channel messages to servers.
The default is 'auto' which uses multicast but switches to broadcast
when channel mode +H is set. This is what people should normally use.
If you set it to 'never' then +H will not work properly if there are
servers with 0 users on them.
in case of a change in the quit comment, such as color stripping / blocking.
The default is 'no', but some users may like this to be 'yes' so things like
+S only affect the channel and not the quit for all channels.
This hereby also lays the groundwork for some next commits of 'i' :)
The configuration item name may still change if I think of a better one....
maximum number of conversations a user can have with other users at the
same time. Until now this was hardcoded at limiting /MSG and /INVITE to
20 different users in a 15 second period. The new default is 10 users,
which serves as a protection measure against spambots.
See https://www.unrealircd.org/docs/Set_block#maxcc for more details.
* You can now set more custom limits. The default settings are shown below:
set {
topic-length 360; /* maximum: 360 */
away-length 307; /* maximum: 360 */
quit-length 307; /* maximum: 395 */
kick-length 307; /* maximum: 360 */
};
* A new 005 token has been added: QUITLEN. Works similar to KICKLEN.
The ability to adjust the topic length in the configuration file was
requested by Amiga600 in https://bugs.unrealircd.org/view.php?id=4692
At that place is also additional information on why there is a
"maximum" for topic length.
to control synchronization of the +beI setter across server links
(that is, the feature just introduced one commit ago):
set {
topic-setter [nick|nick-user-host]; /* nick = default */
ban-setter [nick|nick-user-host]; /* nick = default */
ban-setter-sync [yes|no]; /* yes = default */
};
This also means that --with-topicisnuhost / TOPIC_NICK_IS_NUHOST
is now removed, since this now goes via set::topic-setter.
Also, moved the "first" PROTOCTL from include/common.h to send_proto()
in src/s_serv.c so the bunch of PROTOCTL lines is all in one place
(and so I could conditionally send SJSBY).
Ok, it's not entirely all in one place, PROTOCTL EAUTH is still sent
at another place (early, duh), but still..
that use outdated SSL/TLS protocols (eg: TLSv1.0) and ciphers.
The default settings are to warn in all cases: users connecting,
opers /OPER'ing up and servers linking in. The user will see a message
telling them to upgrade their IRC client.
This should help with migrating such users since in the future, say one
or two years from now, we would want to change the default to only allow
TSLv1.2+ with ciphers that provide Forward Secrecy. Instead of rejecting
clients without any error message, this provides a way to warn them and
give them some time to upgrade their outdated IRC client.

places by spamfilters (and some other systems) to be placed not on *@ip
but rather on user@ip. Note that this won't work for ZLINE/GZLINE since
no ident/username lookups are done in such cases.
Bit of a niche feature but okay..
This allows you to for example specify a specific certificate/key on an
serversonly port and in link block (a self-signed 10 year valid certificate)
and use a short-lived (XX day) Let's Encrypt certificate on the other ports.
And several other uses, of course.
Accepted values are: All (enable all), TLSv1, TLSv1.1, TLSv1.2
You can use + and - modifiers, in fact you are encouraged to.
Example: set { ssl { protocols "All,-TLSv1,-TLSv1.1"; }; };
This will only allow TLSv1.2 at time of writing, and later whenever
TLSv1.3 is released it will allow TLSv1.2 and TLSv1.3.
Note that 'SSLv2' and 'SSLv3' do not exist, as UnrealIRCd 4.x never
supported these old versions (and never will).
