Special modes like +j can be tracked easily just by adding the necessary
code to parse them to set_channel_mlock(). This will cover propagation
as well.
Such bans are not applied locally, but are propagated normally.
They can only be removed on a server that applies them.
Note that normally KLINE will not accept such bans.
This is mainly for services, differing min_wildcard and
ircd changes.
A KLINE command without the ON clause now sets a propagated
("global") ban. KLINE commands with the ON clause work as
before.
Propagated klines can only be removed with an UNKLINE command
without the ON clause, and this removes them everywhere.
In fact, they remain in a deactivated state until the latest
expiry ever used for the mask has passed.
Propagated klines are part of the netburst using a new BAN
message and capab. If such a burst has an effect, both the
server name and the original oper are shown in the server
notice.
No checks whatsoever are done on bursted klines at this time.
The system should be extended to XLINE and RESV later.
There is currently no way to list propagated klines,
but TESTLINE works normally.
The value 0 indicates the creation time is unknown (currently the case
for bandb).
Also store a creation time for xlines and resvs, but do not use it yet.
identd and SASL can cause source_p->user to be present without USER having been sent.
Without this change, that could cause a crash later on as localClient->fullcaps is not initialised.
The behaviour is the same as /msg except that where
/msg would send RPL_UMODEGMSG to the user, the /invite
is instead let through. This counts as a notification
for caller_id_wait like RPL_UMODEGMSG.
Checks are on the target user's server, which means an
error message will appear after RPL_INVITING.
This must be because the accept list is not globally
known.
Similar to /msg, inviting a user that is not in a channel
you have op or voice in requires a free target; opers always
have a free target.
Being invited adds the source as a reply target.
When a user receives a private message, notice or RPL_UMODEGMSG,
add the source to a special set of 5 target slots.
These slots are checked in the normal way when sending messages,
allowing a reply without using up a free target.
This feature will not be very useful if a user is being messaged
by many different users; to help this, messages blocked entirely
by +g or +R do not affect the targets. CTCP replies also remain
free in terms of targets.
The server protocol for this is
:<uid> ENCAP * CERTFP :<40 hex chars>
both in new user introductions and in burst.
As in oftc-hybrid, only the user themselves and opers can see the certfp.
Displaying the certfp on connect seems unnecessary to me,
the user can whois themselves if needed.
