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)
Just as a reminder: don't blindly assume that if anything is set here
that the user is logged in, there is IsLoggedIn(client) for that.
Reason: if the account name starts with a digit or is "*" then the
user isn't actually logged in ;)
This means we now have $client.user.username but the expansion system
does not allow items more than 2 deep atm (only $client.something
but not $client.something.other). Will fix later. (TODO)
In the meantime the connection notice will look weird :D
Based on previous reports and patches from k4be in
https://github.com/unrealircd/unrealircd/pull/129
Looks much cleaner now.
This also filters out the edge case where user_account_login()
could have been called when a user transitioned from "not logged in"
to "unconfirmed account". It did not cause any issues AFAICT but
it is not really expected either.

This does two things in cmd_uid() now:
* It checks if parameter 6 in UID is a valid UID, using valid_uid()
* It checks if the first 3 characters of the UID match the SID
