Bram Matthys f8bee4941a Some fixes due to the sendnumeric() migration (see previous commits). 2019-05-22 12:58:38 +02:00
Bram Matthys 39029555cb A few more sendnumeric() conversions, putting numerics in main file. 2019-05-22 12:39:01 +02:00
Bram Matthys 7e4bfbc7c3 Move more to sendtxtnumeric()... and some sendnumeric() leftovers. 2019-05-22 12:10:57 +02:00
Bram Matthys 1a4cbb7023 sendnumeric() - phase 2 2019-05-22 11:41:46 +02:00

Bram Matthys 5fb9b12d5e Mass-replace sending of notices with sendnotice(), which exists for quite a while now ;) 2019-05-22 09:34:34 +02:00
Bram Matthys a320bec089 More message tags support in the API. sendto_server() now has mtags
and sendto_match_butone as well.
Still about 15 FIXME's that need to be resolved, but committing early.
2019-05-21 19:00:35 +02:00
Bram Matthys c3a929646c Move src/modules/cap/* to src/modules/ as the meaning got blurred.
For example, msgid / message-ids is not a CAP, while server-time is.
There mere fact of something being in CAP or not shouldn't cause
something to be in different directories ;).
2019-05-19 15:58:34 +02:00
Bram Matthys da31011b30 Move most of the message-tags stuff to the message-tags module. 2019-05-19 15:41:24 +02:00
Bram Matthys 13c59febbf Support for optional efunctions, with a default handler. 2019-05-19 09:49:53 +02:00
Bram Matthys 4e17f85fe6 1) New function new_message() which should be called when a new message is
sent, or at least for channel events.
2) Move adding of msgid/time/account tags to modules,
   which is their proper place.
2019-05-19 09:24:38 +02:00
Bram Matthys 10dcacdb0a @define, @if, @endif are all working.
You can do something like:
@define $SERVERIP "1.2.3.4"
listen {
    ip $SERVERIP;
    port 6667;
}

Supported @if types:
@if $VARIABLE == "something"
@if $VARIABLE != "something"
@if defined($VARIABLE)
@if !defined($VARIABLE)
@if module-loaded("somename")
@if !module-loaded("somename")

Bram Matthys 35fa6cedac Convert some alloc+strlcpy to safestrldup in config code.
-curce->ce_vardata = MyMallocEx(ptr-start+1);
-    strlcpy(curce->ce_vardata, start, ptr-start+1);
+safestrldup(curce->ce_vardata, start, ptr-start+1);

Bram Matthys 1adb02b56b Move new preprocessor from yesterday to it's own file (src/conf_preprocessor.c) 2019-05-18 13:58:27 +02:00
Bram Matthys fad8c35847 Initial support for dynamic configuration, $define, $if, $endif.
Early commit, still cleaning up to do.
But what works is:

$define SERVER      "hub.example.org"

$if SERVER == "hub.example.org"
link .... {
....
}
$endif

$if defined(SERVER)
....
$endif

And also we have mod-loaded() which even works half-way in a block
such as in helpop:
help Chmodes {
[..]
$if module-loaded("chanmodes/stripcolor")
        " c = Block messages containing mIRC color codes [o]";
$endif
$if module-loaded("chanmodes/noctcp")
        " C = No CTCPs allowed in the channel [h]";
$endif
};

As said, still need to cleanups and there are some limitations.
Also the idea is to be able to use defined values in variable names/values
but that has not yet been implemented.
2019-05-17 20:43:36 +02:00
Bram Matthys 7204f156c2 Store relative path and is_module_loaded() now has a small behavior change.
You now call it with a path like is_module_loaded("extbans/timedban").
This, among other reasons, so you can differentiate between modules with
the same name, such as "usermodes/noctcp" and "chanmodes/noctcp".

Bram Matthys 5ebd096f16 Initial implementation of message-tags from May 5, 2019.
This also includes buffer modifications to have a larger read buffer
and IRCv3 implementations (partial or not) for:
labeled-response, msgid, server-time, batch and account-tag.

As said, it is the initial and partial implementation.
There are still various FIXME's and TODO's, the API of various
functions may still change (actually that is true for the next
months, even) and some stuff is currently in the core that will
be moved to modules.
2019-05-12 13:46:44 +02:00
Bram Matthys a87d54355a Update version to 5.0.0-dev

Bram Matthys 4981bf472c Bump reputation version from 1.0.1 to 1.2 2019-05-11 14:17:45 +02:00
Bram Matthys 3a0d8fc06c Fix another reputation issue: reputation not showing in WHOIS when
a remote user has just connected (could take up to 5 minutes) and
a fix required for previous commit for connthrottle.

Bram Matthys 7a7266bc2f Bump connthrottle version from 1.1 to 1.2 2019-05-11 14:02:42 +02:00
Bram Matthys 64c8096361 Fix connthrottle module counting non-local connecting registered users
always as new users (regardless of reputation), causing the protection
to kick in too quickly for the poor new users. This was noticeable
after for example one server died and new users reconnecting massively
to the remaining servers. Reported by Lord.

Bram Matthys 09d31d8ded Enhance WHOX->WHO auto-conversion for +s serv.er.name, reported by k4be. 2019-05-03 13:15:17 +02:00
Bram Matthys 8a6cbfaaf0 Show linking error messages if these happen during the handshake and we
have already fully authenticated the server (but when it technically is
not fully linked as a server yet, eg post-EAUTH but pre-SERVER).

Also, send ERRORs to junk snomask from untrusted sources. After all,
the junk snomask is precisely there to enable briefly to debug issues.
In case of link errors we always advice to check BOTH sides of the link
as an IRCOp, and this advice still stands. This may just help a little
for people who do not follow our advice.
2019-05-02 09:30:15 +02:00
Bram Matthys 5b63d28e2a Improve error messages in case of failed server linking due to mixed
password types (eg: plaintext on one side, spkifp on the other side).
Refer to https://www.unrealircd.org/docs/FAQ#auth-fail-mixed

Also, unrelated to the above, don't say "Bad password?" if the
password type is not of type plaintext, since it would be confusing.

Bram Matthys 377fa25244 UnrealIRCd 4.2.3 2019-04-30 09:23:44 +02:00
Bram Matthys f9bbeaa6ca [nopost] Send these harmless kill messages to the junk snomask.
Nowadays these are pretty much never proxy attacks. Only scanners and
crawlers trying HTTP commands on IRC connections.. which isn't even that
weird anymore since people tend to open up port 443 for SSL/TLS IRC
to bypass firewall restrictions.

Bram Matthys 11c6604aeb Print out clear warning/error if using an old spamfilter.conf.
For example for Windows users, or for *NIX users where the automated
patching of the spamfilter.conf did not work.
I've tried to make the error message as clear and big as possible
and the wiki article as clear as possible as to what the user needs
to do. Not much more I can do.... :)

Bram Matthys 3aa5048300 Improve error message if someone uses set::something literally in the
configuration file.
Also, make (global)'unknown directive' errors fatal, as they should be.

Bram Matthys 5c30d1af6d * Badword blocks now use PCRE2 if using regex at all (rare,
usually the fast badwords system is used instead)
* Code deduplication in src/modules/{chanmodes,usermodes}/censor.c
  to src/match.c -- which may be moved later again to efuncs.
* Add --without-tre:
  This means USE_TRE will be enabled by default right now
  but if using --without-tre it will be undef'ed. This so we
  can prepare for the TRE phase-out in 2020.
* Remove include/badwords.h, put contents in include/struct.h

Bram Matthys 6d3a98653e The maximum number of clients (MAXCONNECTIONS) no longer defaults to 1024.
The new question in ./Config now defaults to 'auto' (both for new installs
and for upgrades). You can still specify a manual limit but it is no longer
recommended.
A MAXCONNECTIONS of 'auto' means - at present - that UnrealIRCd will try
to set a limit of 8192. This is quite a bump from the original 1024.
On systems where this is not possible we will simply use the highest amount
possible, such as 4096 on many systems, or 1024.
In fact, we now no longer error when MAXCONNECTIONS is higher than the
'ulimit -n' limit but will adjust ourselves to the limit.
Only if the effective limit is below 100 we will print out a fatal error
since running in such a scenario is highly discouraged.
The reason for this change is that nowadays with drone attacks we may need
to be able to handle more concurrent sockets. Also, many Linux distro's
have a default setting of unlimited or 4096 nowadays, out of the box.

For people packaging UnrealIRCd (not end-users):
The ./configure --with-fd-setsize=xx option was removed and the
optional(!!) --with-maxconnections=xx option has been added.
We recommend you NOT to pass this option. Not passing it means that
the previously mentioned 'auto' mode will be used, which is likely
best for most users.

Module coders:
Although it is unlikely you accessed the 'MAXCLIENTS' variable,
if you did, it is now called 'maxclients' (lowercase) since it is
adjusted at runtime and no longer a macro.
