So you can just use mask { ip { 127.*; 192.168.*; } } without
having to worry about hostnames like 127.example.net.
(Of course you could also have used CIDR notation)
Another benefit is that, since we are dealing with IP's only,
the matching is faster than going through the more universal
match_user() routine.
So now the example in the release notes actually works:
except ban {
mask { security-group irccloud; }
type { blacklist; connect-flood; handshake-data-flood; }
}
The list of channels (which is an array) is limited to a total
of 384 characters after JSON expansion. If it is limited then
the last item will be "...".

The "vhost" field is added if the visible host of the user differs
from the real hostname, such as +x with cloaking or +xt with a vhost.
The "cloakedhost" is always included, even if the user does not
currently have a cloaked host at all (eg is -x or using a vhost).
Both make it easier to search log files based on user reports.
Eg a user mentions a vhost or cloaked host from their user logs
and then a server admin searches the UnrealIRCd logs on this to
retrieve the real host / ip / user based on that.

(It is not under "user" because the info can be useful before someone
is considered a user, eg when flooding/rejected/etc)
clients etc. are expanded in the logging routines.
HOOKTYPE_JSON_EXPAND_CLIENT - for all clients
HOOKTYPE_JSON_EXPAND_CLIENT_USER - for clients that are users
HOOKTYPE_JSON_EXPAND_CLIENT_SERVER - for clients that are servers
HOOKTYPE_JSON_EXPAND_CHANNEL - for channels
on each string. Note that the entire JSON dump may still be much larger,
this is just about each individual string item within an object.
This commit also adds a more flexible StripControlCodesEx() function
to the core (which is used by the logging system), the existing
StripControlCodes() function is unchanged and can still be used.
+/** Strip color, bold, underline, and reverse codes from a string.
+ * @param text The input text
+ * @param output The buffer for the output text
+ * @param outputlen The length of the output buffer
+ * @param strip_all_low_ascii If set to 1 then all ASCII < 32 is stripped
+ * (the ASCII control codes), otherwise we only
+ * strip the IRC control- and color codes.
+ * @returns The new string, which will be 'output', or in unusual cases (outputlen==0) will be NULL.
+ */
+const char *StripControlCodesEx(const char *text, char *output, size_t outputlen, int strip_all_low_ascii)

this is a https://www.unrealircd.org/docs/Mask_item so very flexible.
Note that most people would want to use except ban { } instead to
simply exempt from ALL blacklists. (that one does not yet have the
flexible mask capability though.. but it wil have it soon..)
Pretty much everywhere we had:
0001 userhost_changed(client);
0002 if (MyUser(client))
0003 sendnumeric(client, RPL_HOSTHIDDEN, client->user->virthost);
Lines 2-3 are now integrated in userhost_changed().
Also fix two issues with CHGHOST in make_oper():
* if user was -x, modes had +x and a vhost, it would send the cloaked
host in the original vhost, while it should have been the real host
* if user was -x and went +x without vhost (so only uncloaked to cloaked)
then no CHGHOST message was sent at all
Automatically convert the old options ::sasl-bypass, ::webirc-bypass
and ::minimum-reputation-score, so nobody needs to update their config.
The example.conf has been updated.
(Also call it allow::match in the future, but accept allow::mask still)
This is the first of several commits to convert all ::mask items.
See https://www.unrealircd.org/docs/Mask_item for the consequences.
In short, you can now use all of the security-group items directly
in a mask, eg:
allow {
mask { account TrustedUser; }
class clients;
maxperip 10;
}
The extban module API is used behind the scenes. To the server admin
the functionality appears in a more natural way:
account { <list>; };
country { <list>; };
realname { <list>; };
certfp { <list>; };
In the same way, they appear as exclude-xxx options too:
exclude-account { <list>; };
exclude-country { <list>; };
exclude-realname { <list>; };
exclude-certfp { <list>; };
Modules can add additional fields (3rd party modules too!).
Module coders:
See src/modules/extbans/realname.c for a simple example. In short:
1) You need to register your extban in both MOD_TEST and MOD_INIT
2) Other than that, the existing rules for extended server bans apply:
a) Your req.is_banned_events needs to include BANCHK_TKL
b) Your req.options needs to include EXTBOPT_TKL
Be advised that for modules that are called in extended server bans
the client may be missing several fields, for example client->user could
be NULL, so be careful with accessing everything in your module.
security-group { mask ~security-group:xyz; }
Module coders (again, slightly unrelated):
Added unreal_add_names() function which can be used to transform
a list of names in the config to a linked list (NameList).
security group that references another (or itself), eg:
security-group abc {
include-mask ~security-group:abc;
}
We now give up after a recursion depth of >8 and log a warning.
been connected to IRC. See https://www.unrealircd.org/docs/Security-group_block
Slightly unrelated, for modules coders: new function get_connected_time(),
to see how long a client has been online. This works for local clients, in
which case it would just return TStime()-client->local->creationtime.
It also works for remote clients, for which it will use the newly added
"creationtime" moddata (commit f1a18ce37e),
so the info is only available for remote clients on newer servers.
If the info cannot be found it will return 0 (zero).
The set::whois-details name for this is: security-groups.
https://www.unrealircd.org/docs/Set_block#set::whois-details
By default it is shown ONLY to IRCOps, not even to 'self' for normal users.
If you want to hide it for everyone, even to IRCOps, eg because you
feel it is useless information, then you can use:
set {
whois-details {
security-groups { everyone none; self none; oper none; }
}
}
This existed in UnrealIRCd 3.2.x but was later removed when
switching to the new operclass system.

Syntax: SVSO <uid|nick> <oper account> <operclass> <class> <modes> <snomask> <vhost>
All these parameters need to be set, you cannot leave any of them out,
HOWEVER some can be set to "-" to skip setting them, this is true for:
<class>, <modes>, <snomask>, <vhost>
In UnrealIRCd the <operclass> will be prefixed by "services:" if not already
present. It is up to you to include or omit it.
If you want to set any swhoises you need to use the SWHOIS s2s command,
other than that this command basically does everything for you,
in fact it uses the same code as the OPER command does.
Most of the "user is now ircop" code has been moved out of cmd_oper() to
a new function make_oper() that is called by both cmd_oper() and cmd_svso().
This function also changes the hook HOOKTYPE_LOCAL_OPER:
It no longer passes a ConfigItem_oper struct, since we can't do that for
remote opers. Instead it passes oper name and oper class.
The complete definition is now:
int hooktype_local_oper(Client *client, int add, const char *oper_block, const char *operclass);
