Hopefully this fixes a crash when linking (succesfully authenticated) servers,
something which only happens with GCC and only for some people in some cases.

This also adds a new function convert_regular_ban() which is now
used by both clean_ban_mask() and extban_conv_param_nuh().
This also moves some of the adding code (sending notice, broadcasting to
other servers, etc) to a function tkl_added().
We should probably do the same for deletion and not use the tkllayer
anymore for that?
Currently available:
* server_ban.list
* server_ban.get with params: name="*@1.2.3.4", type="kline"
This also adds server_ban_parse_mask() which is now used by both GLINE/etc
and the RPC API to parse the same way and convey the same error messages.
chunked encoding stuff is copied from the modulemanager and #if'd out.
The non-chunked is not OK yet either, as it must check the Content-Length,
while we currently assume a single packet == the complete request.
This is start_of_normal_client_handshake() by default, but is
start_of_control_client_handshake() for the control channel
(for './unrealircd rehash' and such). Previously that was hardcoded.
It is also used by the RPC code now.
These deal with set::anti-flood::everyone::connect-flood and
set::max-unknown-connections-per-ip respectively.
This adds a new hook HOOKTYPE_ACCEPT, that is mostly meant for internal
usage by UnrealIRCd. Most module coders will want to use the existing
hook HOOKTYPE_HANDSHAKE instead.
This also gets of check_banned() which is now spread over the individual
modules (eg: checking banned is done in tkl on HOOKTYPE_ACCEPT and
HOOKTYPE_IP_CHANGE).
if the oper block permits, the user does not have to send "OPER xyz".
Eg:
security-group Syzop { certfp "xyz"; }
oper Syzop {
auto-login yes;
mask { security-group Syzop; }
operclass netadmin-with-override;
class opers;
}
Then, if you connect with SSL with that certificate fingerprint,
you become IRCOp automatically.
and other selectors in 'mask'. This allows for things like:
security-group Syzop { certfp "xyz"; }
oper Syzop {
mask { security-group Syzop; }
operclass netadmin-with-override;
class opers;
}
except ban {
mask { security-group Syzop; }
type all;
}
allow {
mask { security-group Syzop; }
class special;
maxperip 32;
}
etc...
We do error on the obvious case of mask * and mask *@* when no password
is set, but otherwise try not to stop all cases of user stupidity
(there are just too many...).
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; }
}
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)
{
(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).
