when there is already another established link with a server with the same name.
For example, when there is a network issue and the "old server" is still
waiting to be timed out and the "new server" is already linking in.
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);
This is an easier way to call the next command override handler from command
override functions. It passes the standard parameters so you don't have to
worry about which parameters a CMD_OVERRIDE_FUNC() contains.
This so it is easier to change command parameters in future UnrealIRCd versions,
should it be needed, then it may be possible without any source code changes
on the module developer side.
- CallCommandOverride(ovr, client, recv_mtags, parc, parv);
+ CALL_NEXT_COMMAND_OVERRIDE();
and as it should be IMO. Both for invites by channel ops and for OperOverride.
This also fixes a bug where an IRCOp with OperOverride could not bypass +l
and other restrictions. Only +b and +i could be bypassed.
Module coders: HOOKTYPE_OPER_INVITE_BAN is now gone and HOOKTYPE_INVITE_BYPASS
is now new. The HOOKTYPE_INVITE_BYPASS is called when the user is joining
a channel to which they were invited to. If you return HOOK_DENY there then
the join is still blocked, otherwise it is allowed.
Using this hook would be sortof unusual since usually you would want users
to be able to bypass restrictions when they were invited by another user
or when they invited themselves using OperOverride.
The only example where we use it in UnrealIRCd is for +O channels so an
IRCOp cannot use OperOverride to join +O channels when they would otherwise
not be allowed to do so. Actually even that is a corner case that you could
debate about, but.. whatever.
Hopefully this fixes a crash when linking (succesfully authenticated) servers,
something which only happens with GCC and only for some people in some cases.

This also adds a new function convert_regular_ban() which is now
used by both clean_ban_mask() and extban_conv_param_nuh().
More precise, for extended server bans, usermask/hostmask was set to
a local variable that was not defined as static char[]. This would lead
to corrupt data and/or crashes.
Bug introduced a few days ago with 3d9b7e4b70
This also moves some of the adding code (sending notice, broadcasting to
other servers, etc) to a function tkl_added().
We should probably do the same for deletion and not use the tkllayer
anymore for that?
Currently available:
* server_ban.list
* server_ban.get with params: name="*@1.2.3.4", type="kline"
This also adds server_ban_parse_mask() which is now used by both GLINE/etc
and the RPC API to parse the same way and convey the same error messages.
Previously we did show a warning but we could crash a millisecond
later so that wasn't particularly helpful.
Now, is_module_loaded() can be used from HOOKTYPE_CONFIGPOSTTEST
to detect if a module is loaded or not, contrary to us having to
do it in MOD_LOAD when it is too late. So now the requirement is
really enforced and also works for hot-loading as well as
unloading of required modules is now prevented.
chunked encoding stuff is copied from the modulemanager and #if'd out.
The non-chunked is not OK yet either, as it must check the Content-Length,
while we currently assume a single packet == the complete request.
This is start_of_normal_client_handshake() by default, but is
start_of_control_client_handshake() for the control channel
(for './unrealircd rehash' and such). Previously that was hardcoded.
It is also used by the RPC code now.
