Bram Matthys 5182c664d1 Easier API for just-commited persistent variables. Example:
LoadPersistentPointer(modinfo, removefld_list, floodprot_free_removefld_list);
SavePersistentPointer(modinfo, removefld_list);

The above example was for a pointer, there are also functions for int and long,
which are even more simple:
LoadPersistentInt(modinfo, somevar)
SavePersistentInt(modinfo, somevar)
and
LoadPersistentLong(modinfo, somevar)
SavePersistentLong(modinfo, somevar)
both are untested, but will be tested soon...

Bram Matthys 0920967cc4 New module_load_variable / module_save_variable functions
and made floodprot to use these functions.
TODO: 1) Different functions for pointer/int/long, 2) macro?
2019-06-28 21:02:29 +02:00
Bram Matthys 7fe1848340 Make floodprot no longer PERM so it can be reloaded. Useful if we ever
make a mistake in the module so we can upgrade it on-the-fly.
Or if someone wants to get rid of it.
TODO: consider abstracting the saving/restoring of vars.

Bram Matthys 38e9c100d4 Get rid of include/threads.h (unused) 2019-06-26 17:27:45 +02:00

Bram Matthys d5b643ceee Rewrite hash table code to use SipHash (more to follow) 2019-06-26 13:24:02 +02:00
Bram Matthys 7161f33311 Code cleanup: make src/*.c use the generic #include "unrealircd.h" file
(with only a few exceptions)
Now, we'll find out later if Windows still compiles, I guess ;)

Bram Matthys e03c8135a9 CHFL_CHANPROT -> CHFL_CHANADMIN, is_chanprot -> is_chanadmin
These are just remnants of the past, when +a was called channel protection.
It is called channel admin since as long as I can remember, and in 90%
of the code and documentation it is called that way.
2019-06-22 17:32:57 +02:00
Bram Matthys cf29aa8feb Replace various 90% identical functions with some macro's instead. 2019-06-22 17:29:03 +02:00
Bram Matthys bf4d96e991 can_send() now returns 0 (false) or 1 (true), rather than magic values.
Also, the HOOKTYPE_CAN_SEND prototype changed so you can communicate
the error message in a flexible way, similar to what I just did
with extbans.
2019-06-22 15:57:32 +02:00
Bram Matthys 1cfebcf05e Add new set::part_instead_of_quit_on_comment_change to convert QUIT to PART
in case of a change in the quit comment, such as color stripping / blocking.
The default is 'no', but some users may like this to be 'yes' so things like
+S only affect the channel and not the quit for all channels.
This hereby also lays the groundwork for some next commits of 'i' :)
The configuration item name may still change if I think of a better one....

2019-06-12 18:59:12 +02:00
Bram Matthys a2ee5d67f3 Update a few hooks to include mtags, more will follow later.
This fixes inconsistent mtags accross server links with delayjoin.
2019-06-07 15:05:10 +02:00
Bram Matthys 1f2bb0d89b Delayjoin: if kicking invisible user we used to clear the invisibility
status of the victim (JOIN+KICK). That seems unnecessary to me, since
there is already code in place to handle this -- hopefully it works too.
2019-06-07 14:41:01 +02:00
Bram Matthys 0e68265e12 Remove sock.h old compatibility code. Shouldn't be needed anymore.
(This provided FD_ZERO and such if the OS/libc did not provide it)
2019-06-07 12:42:28 +02:00
Bram Matthys daab5abc92 Manual audit of sendto_one(): add mtags support where necessary. 2019-05-24 21:09:55 +02:00
Bram Matthys 6e5df1a4c0 Add mtags argument to sendto_one(). Phase 1 (automated), next is manual
audit of all sendto_one's. Also it doesn't work yet...
2019-05-24 17:38:48 +02:00
Bram Matthys f8bee4941a Some fixes due to the sendnumeric() migration (see previous commits). 2019-05-22 12:58:38 +02:00
Bram Matthys 7e4bfbc7c3 Move more to sendtxtnumeric()... and some sendnumeric() leftovers. 2019-05-22 12:10:57 +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 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".
2019-05-17 18:48:37 +02:00
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 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 dd2af3b31c Enable additional compiler warnings. Update code to conform to these
new standards, possible to compile with -Werror with them.

Bram Matthys ad173cc5d0 Ignore join flood check in channel mode +f when the server just booted.
This new option is called set::modef-boot-delay (default: 75 seconds).
See https://www.unrealircd.org/docs/Set_block#set::modef-boot-delay
2019-03-25 13:27:28 +01:00
Bram Matthys 5b20716e9b [cleanup] floodprot: move set::modef-* handling from core to module. 2019-03-25 13:10:03 +01:00
Bram Matthys cb60bf286d Get rid of this useless DLLFUNC junk. This is only needed for symbols
that need to be visible from the outside of the .DLL (symbol export).
Long story short: you never need to use this yourself in a module.
Where needed it is already handled by UnrealIRCd.
2019-03-23 19:53:12 +01:00
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 a0167c35c0 Major reorganization of operclass privileges:
* The operclass privileges have been redone. Since there were 50+ changes
  to the 100+ privileges it makes little sense to list the changes here.
  If, like 99% of the users, you use default operclasses such as "globop"
  and "admin-with-override" then you don't need to do anything.
  However, if you have custom operclass { } blocks then the privileges
  will have to be redone. For more information on the conversion process,
  see https://www.unrealircd.org/docs/FAQ#New_operclass_permissions
  For the new list of permissions, with much better naming and grouping:
  https://www.unrealircd.org/docs/Operclass_permissions
The inconsistency in the privileges was initially reported by webczat in
https://bugs.unrealircd.org/view.php?id=4771
The subsequent reorganization took two full days, so.. hopefully the
people who are using - or plan to use - custom operclasses will like the
new layout... except that they need to redo their work of course ;)

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);

Bram Matthys d5d446c38d More code cleanups to get rid of useless casts and other useless
structures such as:
-       lp->value.cp = (char *)MyMalloc(strlen(mask) + 1);
-       (void)strcpy(lp->value.cp, mask);
+       lp->value.cp = strdup(mask);

Bram Matthys 079963cdc6 Set prio for HOOKTYPE_CHANNEL_DESTROY to -1mln so other hooks are

Bram Matthys aa093f3e2b Timedban support in +f [5t#b2]:10 (set 2 minute ban on text flood).
Naturally this is only available if the extbans/timedban module is
loaded and you should do so on all your servers on the same network
if you want to avoid confusion/desynchs.

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 704487e124 Fix numerous crash bugs in server to server code.
In 3.2.x we didn't fix these bugs since servers are trusted and
should send correct commands. In 4.0.x we changed this so we would
fix them when we come across such issues at normal priority (not
consider them security issues). I now took it a step further and
actively checked/looked for these issues and a bunch of them were
found. Almost all are NULL pointer dereferences, with some exceptions.
* S2S: MODE: check conv_param return value (NULL ptr crash)
* S2S: MODE: floodprot: More checks (NULL ptr crash)
* S2S: MODE: OOB write of NULL (write NULL past last element in an array)
* S2S: NICK: old compat fixes (NULL ptr crash)
* S2S: PROTOCTL: Check for double SID=
* S2S: SERVER: require at least 3 parameters (NULL ptr crash)
* S2S: SJOIN: require at least 3 parameters (NULL ptr crash)
* S2S: SJOIN: Fix OOB read (read 1 byte past buffer)
* S2S: TKL: validate set_at and expire_at (NULL ptr crash)
* S2S: TKL: require at least 9 parameters for spamf, not 8 (NULL ptr crash)
* S2S: TKL: ignore invalid spamfilter matching type (remove abort() call)
* S2S: TOPIC: querying for topic is not permitted (NULL ptr crash)
* S2S: UID: require 12 parameters (NULL ptr crash)
* S2S: WATCH: this is not a server command (NULL ptr crash)
* Fix OOB read (1 byte beyond string) for timevals. This was reachable
  from config code, TKL (S2S) and /*LINE (Oper). In practice no crash.
* MODE: make code less confusing (effectively no change)
* TRACE: remove strange output in case of 0 lines of output
* Fix unimportant memory leak on boot (#4713, reported by dg)
* Fix small memory leak upon 'DNS i' (oper only command)
* Always work on a copy in clean_ban_mask(). This fixes a bug that could
  result in a strlcpy(buf, buf, sizeof(buf)). So, overlapping strings,
  which is undefined behavior.
2017-10-29 11:20:52 +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).
