Fix force-rejoin not working if doing SVSMODE -x/+x (Koragg, #5015).
Note to module coders:
Please use the following procedure in case of an user/host change:
* userhost_save_current(acptr);
* << change username or hostname here (or both) >>
* userhost_changed(acptr);
This function will take care of notifying other clients about
the userhost change, such as doing PART+JOIN+MODE if force-rejoin
is enabled, and sending :xx CHGHOST user host messages to
"CAP chghost" capable clients.
Also, small note to everyone:
If force-rejoin is enabled we will not send the PART+JOIN+MODE to
"CAP chghost" capable clients. Doing so is just a hack to notify
people of a userhost change. "CAP chghost" users can thus benefit
from the reduced noise in this respect.
Delete CAP CLEAR as it's use is discouraged (too much trouble).
Delete CAP ACK (from client2server) as this is only for CAP's with
ack modifiers. This is something we don't use, and which has been
deprecated in v3.2 of the spec.
This permits multiple blocks like..
webirc {
mask *;
password "....." { sslclientcertfp; };
};
..should you need it.
In other words: we don't stop matching upon an authentication failure.
to validate the certificate of the link, making sure that:
1) The certificate is issued by a trusted Certificate Authority (CA).
2) The name on the certificate matches the name of the link block.
Some things still need to be done: documentation, more testing, and
using the X509_check_host() function when available.
Nobody used this option and it only caused the following confusing
(and potentially insecure) behavior:
Previously if you had 'verify-certificate' enabled then the certificate
would be checked, BUT if it was a self-signed certificate (and thus
not passing verify-cert) it was STILL allowed unless you also
specified the 'no-self-signed' option. This might be correct as per
documentation but is way too confusing for the user.
Now you simply have to choose whether you verify the certificate or
not. No special handling for self-signed certificates.
connected to a server introducing himself as irc2.test.net. This
was rather confusing, of course. Wasn't much of a security issue since
this only happened in outgoing connects and naturally all authentication
need to pass as well.
* The 'ban too broad' checking was broken. This permitted glines such
as 192.168.0.0/1 being set. Now it rejects CIDR of /15 and lower.
To disable this safety measure you can (still) use:
set { options { allow-insane-bans; }; };
Docs: https://www.unrealircd.org/docs/Set_block#set::ssl::sts-policy::port
Example:
set {
ssl {
certificate "ssl/server.cert.pem";
key "ssl/server.key.pem";
sts-policy {
port 6697;
duration 180d;
};
};
};
IMPORTANT: Only use this if you know what STS is and what the
implications are. The most important things being A) set a correct
port and B) you need a 'real' SSL certificate and not a self-signed
certificate.
More documentation may follow at another place.
Module coders:
* The cap->visible(void) callback function is now cap->visible(aClient *)
* There is a new cap->parameter(aClient *) callback function.
* Various updates to subfunctions to pass 'sptr' (due to the above),
including clicap_find(sptr, ...)
* New CLICAP_FLAGS_UNREQABLE flag
Other:
* There is a new (src/)modules/cap directory containing the sts module,
well.. once I commit it :D
For example: '+f [5j#i1,5m#m1,3n]:3' and then '+f [5j#i1,5m]:3'
In that case the '3n' was not removed and still effective, as
could be seen by a '/MODE #chan'. Reported by The_Myth (#4883).
