This so users can come online directly with the correct vhost set,
and not first with a standard (usually cloaked) host while auto-(re-)joining
followed by a CHGHOST later.
This is a long outstanding wish from users, I think.
Services can simply send a CHGHOST/CHGIDENT to the UID, for example
right before they send the SASL ... D S message (SASL succeeded)
they can send like: CHGHOST 002ABCDEF some.nice.host
Then UnrealIRCd 6.0.7-git and later will handle the CHGHOST even if
the user is not known yet. Technically, the server where the UID is
on will handle the message. And remote servers that don't know the
user with this UID yet will forward to the server with the SID-portion
of the UID. The CHGHOST will not be a broadcast but the vhost will
show up in the UID protocol message that introduces the user.
For CHGIDENT it is a similar story.
Light testing has been done but more extensive testing is welcomed.
This gets rid of duplicate code in SETIDENT, CHGIDENT, and soon
in the RPC call. It does not get rid of make_valid_username()
in src/modules/nick.c which does something slightly different.
This is only for calls within the same module, as otherwise you
should use do_cmd().
Benefit of this way is that it is short and you don't have to worry
about passing the right command parameters, which may change over time.
Example as used in src/modules/nick.c:
- cmd_nick_remote(client, recv_mtags, parc, parv);
+ CALL_CMD_FUNC(cmd_nick_remote);
but it seems there were still a couple left. These are now gone as well.
There seem to be no issues with the ones that were left, but it is just
too easy to get it wrong. Declaring buf in function now. This should be
faster anyway, since it is located on nearby memory (stack).
Inspired by previous find from westor (c708a99955c034e842f913479cc597d87b311394).
(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;
}
Not that anything is this particular code path should trigger it (OK,
maybe if some 3rd party module kills the user from HOOKTYPE_SECURE_CONNECT)
better safe than sorry.
It means you can no longer modify eg parv[1] in-place with strtoken and such.
The main reason for this is that as a command handler you have no idea
where the arguments may come from. It could be from a do_cmd() with
read-only storage (eg a string literal) and so on.
It started with an experiment of how far I could get and how annoying the
side-effects would be, but they seem to be quite managable, so I'm
committing this stuff.
Hopefully this catches/solves some stupid bugs somewhere :)
server where the client is (or was) on. Just like we did in UnrealIRCd 5.
Not sure if API-wise and variable-name-wise I want to do it this way,
but whatever...
This requires both servers to be using UnrealIRCd 6 and there
should be no UnrealIRCd 5 server in-between (eg an old hub).
This also changes tls_cipher() to expect a Client * argument.
And tls_get_cipher() can now safely be called on any client,
including remote clients, and it will return the cipherstring
if it is known via moddata.
have that in dns.c. Also remove verify_hostname() from dns.c and
integrate it in valid_host() which now takes a second argument
named 'strict'. Call valid_host() with strict set to 1 if the
hostname should be checked to be a valid DNS hostname, eg the
host may not contain stuff like ':' or '/'. Use 0 otherwise
for the loose check, eg if you are not sure if the passed host
is an IP address or a host, or if it is for a vhost.
The last 3 were always NULL after the remote/local split from a few commits ago.
And nick and username were useless as well as client->name and
client->user->username were always already set.
these "network settings" and other settings has been lost in time.
Rename some of these variables and macro's.
ircnetwork -> NETWORK_NAME
ircnet005 -> NETWORK_NAME_005
defserv ->? DEFAULT_SERVER
hidden_host -> CLOAK_PREFIX
helpchan -> HELP_CHANNEL
Also one config change (visible to admins):
set::hiddenhost-prefix is now set::cloak-prefix
We still accept the old name, though.
The example conf has been updated as well, but not the wiki yet.
just like client->user is set if the client is a user.
Rename client->srvptr to client->uplink: this is the uplink that the client
is connected to. If the client is a user then it is set to the server that
the client is connected to, if the client is a server then it is set to the
server that the server is connected to (the.. tadah.. uplink).
For local clients it is always set to &me.
for fake lag calculations only (well, except for 1 corner case).
As said, modules should use the new function:
void add_fake_lag(Client *client, long msec)
