Bram Matthys ab50bf2afc Communicate server featureset (and changes) across server links.
Previously various information was only available for directly attached
servers, since it is communicated via PROTOCTL.
Now, we will also communicate information about leafs behind us.
IRCOps can use the /SINFO command to see these server features.
Services codes don't need to do anything, or at least are not expected
to do anything. They can still receive the information and do something
with it, of course...
Read the following technical documentation for full information,
as it will outline very specific rules for using the command S2S:

Bram Matthys 88030c63fb 1) Simplify dealing with isupport (numeric 005) stuff from the config code.
There's now no longer a difference between a rehash or boot.
2) Other cleanups in s_conf.c as well. Looks better now.
3) Sort the 005 tokens alphabetically. Enforcing some other 'logical order'
   was futile and this makes things consistent between rehashes.

For module coders this adds some new functions, such as IsupportSet,
IsupportSetFmt and IsupportDelByName. I'll document them later.

Bram Matthys ac9463a83f Rename hook HOOKTYPE_CAN_SEND_SECURE to HOOKTYPE_SEND_CHANNEL, which is
more descriptive and AFAICT nobody uses this hook in a public 3rd party
module anyway.
2019-01-21 17:02:14 +01:00
Bram Matthys ee20160bc3 Add another type for HOOKTYPE_CONFIGTEST and HOOKTYPE_CONFIGRUN
for CONFIG_LISTEN. This so a module can have custom options in
the listen block. Like all other CONFIG_* options you are supposed
to return 1 if your module handles this option and 0 if not.
From HOOKTYPE_CONFIGTEST you can also return -1 to indicate error
for an option that is handled by the module.
Note that 'cep' is passed, that is the option for the variable
that is being checked, and not the 'ce', the parent of the listen
block. If you want to access the parent, then use ce->ce_prevlevel.

Bram Matthys bcb667c59e New hook HOOKTYPE_WELCOME (aClient *acptr, int after_numeric): allows you
to send a message at very specific places during the initial welcome

Bram Matthys 267c2f3e56 Make authprompt work for soft KLINE/GLINE and soft-xx ban actions
(in registration phase anyway), as promised earlier in the documentation.
2018-12-19 17:42:13 +01:00
Bram Matthys 0254894368 Authentication prompt for non-SASL users:
We previously introduced the "require sasl" block which allows you to
force users from certain IP addresses to authenticate with their nickname
and password via SASL. We now offer a new experimental module called
'saslemulation' which will help non-SASL users by showing a notice and
asking them to authenticate to their account via /AUTH <user>:<pass>.
See https://www.unrealircd.org/docs/Set_block#set::sasl-emulation

Note that this is work in progress, although the functionality of
already works. Still need to do some cleaning and expand the scope.
And more testing...

Bram Matthys 30da2ae553 Module devs: Add priorities for command overrides.
Use: CmdoverrideAddEx(module, name, priority, function)
Suggested by Gottem in https://bugs.unrealircd.org/view.php?id=5143
..and needed by some upcoming stuff.
2018-09-20 20:01:39 +02:00
Bram Matthys 107d8ccf6a * A new require sasl { } block which allows you to force users on the
specified hostmask to use SASL. Any unauthenticated users matching
  the specified hostmask are are rejected.
  See https://www.unrealircd.org/docs/Require_sasl_block
Feature suggestion: https://bugs.unrealircd.org/view.php?id=5107
2018-09-05 11:34:48 +02:00
Bram Matthys d86d4c7c71 Add new option: blacklist-module "<modulename>";
This is meant to blacklist modules that are in modules.default.conf (or
elsewhere). The 'loadmodule' line for any such module is effective ignored.
https://bugs.unrealircd.org/view.php?id=5118
Note: I had to move the loadmodule code. Previously this was done as each
config file (include) was loaded into memory. Now it is done after *ALL*
config files have been read into memory. This shouldn't matter for module
devs, though..
2018-09-01 20:31:14 +02:00
Bram Matthys cf97de890a These should be marked extern. 2018-09-01 19:37:25 +02:00
Bram Matthys 93957fc7ee blacklist module: also check the ip of WEBIRC users.
Suggested by jesopo (#0005098).
2018-06-11 08:53:34 +02:00
Bram Matthys 992bed3c7a Similar to previous commit, change: alter HOOKTYPE_MODE_DEOP function:
-int hooktype_mode_deop(aClient *sptr, aClient *victim, aChannel *chptr, u_int what, char modechar, long my_access, char **badmode);
+int hooktype_mode_deop(aClient *sptr, aClient *victim, aChannel *chptr, u_int what, int modechar, long my_access, char **badmode);
.. this to get rid of a compiler warning and potential problem.
2018-04-22 16:09:10 +02:00
Bram Matthys 4f0f8478cc Update HOOKTYPE_CHANNEL_SYNCED to get rid of compiler warning.
Can't safely use shorts with variable argument functions I think,
or maybe only with reduced type checking which is not what we want.
-void hooktype_channel_synced(aChannel *chptr, unsigned short merge, unsigned short removetheirs, unsigned short nomode);
+void hooktype_channel_synced(aChannel *chptr, int merge, int removetheirs, int nomode);
2018-04-22 16:02:13 +02:00
Bram Matthys b923b57b35 Yeah, we need more room. 2017-11-27 12:22:42 +01:00
Bram Matthys b5b01c5263 Modularize charsys (set::allowed-nickchars). It's still a mandatory
module but at least the code can be updated on the fly (or replaced
with some other secondary alternative module in the future).
src/charsys.c -> src/modules/charsys.c
This also means everyone needs to load the modules/charsys module.
2017-11-27 11:24:25 +01:00
Bram Matthys eb205e04cc Make types future-proof. Fix ~m case for +M.
BypassMessageRestrictionType -> BypassChannelMessageRestrictionType
BYPASS_MSG_* -> BYPASS_CHANMSG_*
2017-11-19 17:12:28 +01:00
Bram Matthys 1b2b28e6c6 New ban exception ~m:type:mask - allows bypassing of message restrictions.
Valid types are: 'external' (bypass +n), moderated (bypass +m/+M),
'filter' (bypass +G), 'color' (bypass +S/+c) and 'notice' (bypass +T).
Some examples:
* Let LAN users bypass +m: +e ~m:moderated:*!*@192.168.*
* Make GitHub commit bot bypass +n: +e ~m:external:*!*@ipmask
* Allow a services account to use color: +e ~m:color:~a:ColorBot

Bram Matthys 512c8fb000 Move the place where we set umode +z (secure). Needed for next. 2017-11-13 16:23:49 +01:00
Bram Matthys 77234b2b8d API change for HOOKTYPE_PRE_INVITE and fix #5023:
* API change for HOOKTYPE_PRE_INVITE:
  (aClient *sptr, aClient *target, aChannel *chptr, int *override)
  Modules must now send the error message instead of only returning
  HOOK_DENY. Also check for operoverride and set *override=1.

This so modules can send their own error messages instead of the
default message being sent ("channel is +V" - which is not true).

Reported by Gottem (#5023).

Bram Matthys 7801dc888d Move CAP NEW "sasl" sending to after EOS (End Of Synch)
This so saslmechs are properly sent in case of services (re)connect,
otherwise the CAP NEW is sent too early when the saslmechs are
not known yet.
NOTE: This makes sending "EOS" mandatory for any SASL servers.
You should be doing this since 14 years ago (it was added
in 3.2beta18 in August 2003) so hopefully that is the case.
Anope is good anyway :)
2017-10-07 19:40:39 +02:00
Bram Matthys 5c7d89a642 Add support for "CAP extended-join". 2017-10-07 18:33:25 +02:00
Bram Matthys 5124e60b7c Add "CAP chghost" support. Internal recode of userhost changes.
Fix force-rejoin not working if doing SVSMODE -x/+x (Koragg, #5015).

Note to module coders:
Please use the following procedure in case of an user/host change:
* userhost_save_current(acptr);
* << change username or hostname here (or both) >>
* userhost_changed(acptr);
This function will take care of notifying other clients about
the userhost change, such as doing PART+JOIN+MODE if force-rejoin
is enabled, and sending :xx CHGHOST user host messages to
"CAP chghost" capable clients.

Also, small note to everyone:
If force-rejoin is enabled we will not send the PART+JOIN+MODE to
"CAP chghost" capable clients. Doing so is just a hack to notify
people of a userhost change. "CAP chghost" users can thus benefit
from the reduced noise in this respect.
2017-10-07 13:31:30 +02:00
Bram Matthys 5399e060fa Send CAP DEL sasl if set::sasl-server squits and CAP NEW when it returns.
(Only to cap-notify and v3.2 clients, of course)
Also fix a "bug" where sts parameters were not shown in CAP NEW tls.
2017-09-30 15:19:29 +02:00
Bram Matthys 7d381086ad Remove CLICAP_FLAGS_CLIACK. Never understood this idea. Unused and deprecated it seems. 2017-09-30 12:35:56 +02:00
Bram Matthys 44052b86c0 Remove CLICAP_FLAGS_STICKY. We don't use this anyway. 2017-09-30 12:33:57 +02:00
Bram Matthys ea651384f8 Add groundwork for draft/sts (more to follow)
Module coders:
* The cap->visible(void) callback function is now cap->visible(aClient *)
* There is a new cap->parameter(aClient *) callback function.
* Various updates to subfunctions to pass 'sptr' (due to the above),
  including clicap_find(sptr, ...)
* New CLICAP_FLAGS_UNREQABLE flag
Other:
* There is a new (src/)modules/cap directory containing the sts module,
  well.. once I commit it :D

Bram Matthys ec9db8fd5f Move match_user() to module (efunc in m_tkl) 2017-03-18 15:00:34 +01:00
Bram Matthys 993b5bc721 The HOOKTYPE_PACKET validation code is wrong, making the hook unusable. 2016-05-23 11:26:54 +02:00
Bram Matthys dd31542e2c Use UID's in MD commands. Add functions / remove duplicate code. Modularize various functions
in src/moddata.c (move them to src/modules/m_md.c as per TODO). Looks good but more testing warranted.

Bram Matthys b2da8251d8 Fix crash on boot if set::modes-on-join contains channel mode 'f'. Reported by LinkServ (#4461). 2015-11-11 10:23:56 +01:00
Bram Matthys 2f112c3efa Update hook prototypes (typechecking). Fix build. Forgot.. in 3.4 these return int now... 2015-09-22 10:43:26 +02:00
Bram Matthys bd7aebc81e upd hook prototypes 2015-09-21 13:40:36 +02:00
Bram Matthys 9ba9d65c7e Add GCC typechecking: we now validate HookAdd... calls, making sure the function (pointer) is as it should. This to avoid crashes and weird behavior in case of a mismatch.
This resulted in 5-10 changes in the existing code where parameters were off.
Hopefully I didn't make too many mistakes when writing the hook prototypes as it was a tedious job.
An (unintentional) benefit of this new system is that you can see the hook prototypes in include/modules.h like:
/* Hook prototypes */
int hooktype_local_quit(aClient *sptr, char *comment);
....
Though, the wiki is likely a better place: https://www.unrealircd.org/docs/Dev:Hook_API

Bram Matthys 15469cae2e Send version information in SERVER command like before (VL). Expand PROTOCTL EAUTH.
PROTOCTL EAUTH=servername,protocolversion,flags,unrealversiontext
This makes deny link { } work again and gives a bit more information too.
Bug reported by GLolol (#4408).

Bram Matthys c478d7d9ef Move some stuff to introduce_user() so we can use it. 2015-07-20 16:42:36 +02:00
Bram Matthys 421b224d8e Fix SSL client certificate fingerprint authentication not working for server linking. Broken since May 23 already. 2015-07-18 22:05:22 +02:00
Bram Matthys afb4c7bebe Rip out remainder of HOOKTYPE_GUEST. Whoops.. were not sending "nick in use" errors (bug caused a few hours ago) 2015-07-12 20:02:00 +02:00
Bram Matthys 372ce82335 Make client capabilities a modular sub-system, as it should have been since the beginning. 2015-07-12 17:10:48 +02:00

Bram Matthys 60356bd97c typo (l -> L) 2015-07-08 18:06:30 +02:00
Bram Matthys 7b02afb3e5 Make MOD_LOAD and MOD_UNLOAD have a useful argument: pass modinfo, just like in MOD_TEST and MOD_INIT.
Change MOD_TEST/MOD_LOAD/etc macro's (this breaks all modules). Now just use this:
MOD_INIT(modulename)
{
// you can access modinfo here.. or other stuff...
}

(Similar to the CMD_FUNC() macro)

Rather than:
DLLFUNC int MOD_INIT(name)(ModuleInfo *modinfo)
{
//...
}

Bram Matthys b37bab0521 Add priority argument to HookAdd... and rename all the ...Ex stuff to just ... 2015-07-08 17:10:37 +02:00
Bram Matthys f58402365c Moved jointhrottle from channel mode +j to set::anti-flood::join-flood
with a default of 3:90 (3 joins per 90 seconds). There's rarely any need
to configure this on a per-channel basis and this way it's enabled by
default for everyone (unless you decide not to load load the module)
2015-07-05 13:31:56 +02:00
Bram Matthys dd3c4ac4f4 Insert an extra parameter in UmodeAdd and SnomaskAdd to indicate "unset this on de-oper". Safer and better than in XYZ places in the code. 2015-06-21 20:37:53 +02:00
Bram Matthys c0f18b3e8e Replace user mode +v ("victim", receive infected DCC notices) with snomask +D (modules/snomasks/dccreject). 2015-06-21 19:48:13 +02:00
Bram Matthys c9523e962d Added HOOKTYPE_SEE_CHANNEL_IN_WHOIS. Make umode +S use it to hide channels.
Also make the '?' and '!' prefixes in channels in /WHOIS output more generic:
both mean you only get to see the channel because you are an ircop, but:
'?' means the channel is +s/+p too (so take extra care)
and '!' means the channel is public but for other reasons hidden in /WHOIS, like umode +p (later) or umode +S.
2015-06-21 10:22:16 +02:00
Bram Matthys 8cb381cc8e Move user mode +S to usermodes/servicebot.
TODO: hide channels in /WHOIS and some more testing. Tomorrow.. ;)
2015-06-20 21:09:17 +02:00
Bram Matthys 4ae1eb23f0 Move user mode +B to usermodes/bot module.
Also add HOOKTYPE_WHO_STATUS.
