Reloading modules sends CAP DEL followed by an immediate CAP NEW:
:staberinde.local CAP * DEL :account-tag
:staberinde.local CAP * NEW :account-tag
This isn't very nice. /modrestart is particularly bad. In order to avoid
doing this, we remember the capability set at the beginning of module
operations, compare that with the set afterwards, and report only the
differences with CAP {DEL,NEW}.
When a server disconnects the client_exit hook will only be called once
but there could be multiple servers and clients behind that server.
After any client exits, check if the agent is still present.
This only supports two addresses as the intended use is 1 IPv4 and 1 IPv6
address on a single-homed host, and the only supported configuration of
outgoing connections to other servers is to bind a single IPv4 or IPv6
address.
Build the same message but send it to the local client first,
so that the echo-message capability works. But don't do it when
sending a message to yourself.
As well as leaking a connid and leaving the connection open,
these calls to free_client() leave the client in the unknown_list
causing check_unknowns_list() to crash when either ptr->data
(ptr being the freed client_p->localClient->tnode) is NULL or
when client_p->localClient is NULL.
Flag the client as an IO error so that we don't try to send it
any data (as this is not a normal plaintext connection).
Links that are 'no-export' are not distributed to the rest of the IRC network (including local peers).
This provides a core primitive for 'anycasting' services (but the actual issue of synchronizing data in
a services package is left to the authors of the services package).
It's useful to allow authd to run in parallel with ssl negotiation,
but if the ssld connection has plaintext data ready for reading
there's a race condition between authd calling read_packet() and
ssl_process_certfp() storing the certificate fingerprint. This
scenario would be bad for a server connecting because fingerprint
verification will fail.
Allow either operation to complete first, but wait until
ssl_process_open_fd() calls the ssl open callback before calling
read_packet().
Don't use the librb callback type as we're always passing client_p.
Provide a return value so that the connect handler can exit_client()
and the accept handler can opt to use the default dead handler.
There's no need to pass information around that sslproc already has access
to, so use ServerInfo directly. Remove the extra NULL checks as these are
already performed before setting ircd_ssl_ok = true.
Fix the server connection configuration so that it can simultaneously
handle a hostname/IPv4/IPv6 for connecting and a hostname/IPv4/IPv6
for binding. Maintains backwards compatibility for matching a hostname
with a mask.
Multiple host/vhost entries can be specified and the last value for
each address family is stored. Hostnames that resolve automatically
overwrite the IP address.
Server connections can now be made to either IPv4 or IPv6 at random
as well as preferring a specific address family.
This also lays the groundwork for the netjoin batch type, but that isn't
implemented yet. I don't like how some of this is implemented but it'll
have to do for now...
Compile tested, needs more testing.
It's a bit of a hack, but better than before. Rather than rehashing
(which could get us into an endless loop), we now segregate the
configuration phase (creating entries ircd-side in case we restart authd
later) and sending phases (when configure_authd() is called). Since we
have to call configure_authd() no matter what (to send timeouts etc.)
and we have to send this data to configure authd anyway, and sending
duplicate data is bad, this is the only way I can think of for now.
It seems to come from an era where long long didn't exist and 64-bit
machines weren't common. 32-bit machines are still common but I can't
imagine this will have much performance impact there.
This "fixes" #179 in title only, but see comments within.
Clean up spaces/tabs mixing mess (bleh), add some defaults for authd
stuff, and get rid of CHARYBDIS_SOMAXCONN (just define SOMAXCONN if it's
available...).
There's no reason to really have these in the main ircd anymore, static
modules are dead and aren't coming back.
To ensure people don't do something hopelessly retarded, this is a core
module.
This also does a lot of surgery on the conf system to reconfigure authd.
/!\ WARNING! ACHTUNG! ADVERTENCIA! ATTENTION! AVVERTIMENTO! /!\
This code has not been run-time tested yet (though it compiles)!
now connid's are allocated on demand and clients may have as many connid's as necessary.
this allows us to build chains of helpers while ensuring the ircd properly tracks and GCs the resources.
