Bram Matthys 9636f83a2b Always assume POSIX signals (on non-Windows, that is). 2019-09-09 16:08:18 +02:00
Bram Matthys 7eb9ed90cb Cleanup sub1_from_channel. Don't kick insecure users on +z channels when we
are merging (equal TS), only kick our users when we are on the losing side
(=if there is a different TS, IOTW: the channel was recreated later).
2019-09-07 14:45:47 +02:00
Bram Matthys 7c9325d8d1 Move get_mode_bitbychar() and get_extmode_bitbychar() to the core
rather than helper functions in floodprot. (I need them)
2019-09-07 09:24:26 +02:00
Bram Matthys 62c0edde12 Partially rewrite SVSMODE #chan code to fix a crash from hostile servers.
Also get rid of the TS parameter in there, which nobody uses anyway.
It didn't even refer to the channel TS.. quite confusing..
it used user->since... so it seems it was against crossing users
(nick changes)... well, we have UID for that now.
2019-09-07 08:02:07 +02:00
Bram Matthys cf873d826a Add MessageTag *mtags argument to various (channel related) hooks, in case
they need access to those. For more information, see:

2019-09-06 14:30:16 +02:00
Bram Matthys 73d320f553 Use enum for BAN_ACT_* and silence a (stupid) clang warning. 2019-09-05 20:54:31 +02:00
Bram Matthys 750479aa2c Add more /ELINE options to bypass the following types: unknown data flood,
antirandom, antimixedutf8 and ban version. Just type /ELINE to see the
options / syntax. (TODO: more testing)
2019-09-04 18:43:06 +02:00
Bram Matthys 58618bf2b6 Add support for ban exceptions, via /ELINE and via the config file.
Still need to fix some FIXME/TODO items and things haven't been
fully tested yet, so server sync issues or crashes are still possible.
Release notes will be updated another day as well..
2019-09-01 20:49:14 +02:00
Bram Matthys 76b1655f9b Add TKL exception type handling (phase 2 of X) 2019-09-01 10:58:29 +02:00
Bram Matthys 3fcd25b542 Split off efunctions to src/api-efunctions.c, use enums and
a different style of initializing the efunctions table which
is less error-prone.
2019-09-01 09:38:55 +02:00
Bram Matthys 8a6c84876e Rewrite/cleanup huge portion of TKL handling (16 files updated, but
src/modules/tkl.c is the main one).
Also move DB writing/reading functions to src/misc.c so they can be
removed out of channeldb and tkldb.

Important note to current tkldb users:
Unfortunately due to the major cleanup I had to remove upgrading
for previously saved tkl db files. That seemed not worth the effort
for maybe <15 current users or so. It also makes the tkldb code
a lot more cleaner. Otherwise it would be a huge mess.

Currently a FIXME item: spamfilter support in RMTKL.

Bram Matthys 0116c4f0d6 Partial TKL recode - (pre) phase 1 2019-08-28 20:21:04 +02:00
Bram Matthys ebaac5a6b8 Get rid of various never used config options and also port
the U4 fix for Windows where it says "Too many connections"
way too quickly. (Sorry for mixing both in 1 commit..)
2019-08-25 17:48:32 +02:00
Bram Matthys 8484511296 Make Windows build compile without warnings with /W3
Disable these warnings, though:
C4267: downgrade of size_t to int and such. pointless...
C4101: unreferenced local variable
C4018: signed/unsigned mismatch
C4244: implicit conversions with "possible loss of data".
       there are 75+ of them and they are likely all harmless
       and/or intentional (usually plain obvious too)
C4996: fixme! warnings about deprecated functions, currently only for GetVersion..
2019-08-25 13:00:31 +02:00
Bram Matthys 33dc939a6d Windows build: remove more warnings. Update Makefile.windows. 2019-08-25 10:04:57 +02:00
Bram Matthys 153e38be10 Get rid of "max sendq" ./Config question, which actually was only
setting the default class::sendq that pretty much everyone overrides
in class (isn't this even required? ;D).
Rename to DEFAULT_SENDQ since we have DEFAULT_RECVQ too.
2019-08-24 19:50:39 +02:00
Bram Matthys 9e02ca2b3c More FORMAT_STRING() checking, get rid of old (non-)USE_VARARGS stuff.
Fix some more bugs (type differences) when compiling in DEBUGMODE.
2019-08-24 19:37:25 +02:00
Bram Matthys 85b3b91b19 Windows build: Add format string verification during build.
(Will be used to hunt and fix those time_t integer type mismatches)
2019-08-24 17:10:44 +02:00
Bram Matthys a6eac922ea Remove unused function create_snomask() 2019-08-23 20:28:48 +02:00
Bram Matthys 02a4bbc348 Get rid of this stupid 'TS' type, just use 'time_t'. 2019-08-22 18:39:28 +02:00
Bram Matthys 33fcc5b550 Enough updates on labeled-response and echo-message for today.
Note that the labeled-response implementation currently requires
'batch' and will always start a BATCH if there is any response.
Later on we can implement a simple queue so we don't have to
start a batch for 1-line responses (which works, but looks a bit
silly if you look at raw server traffic). That may be after alpha1,
though, as there are more (important) things to work on right now.
2019-08-18 09:24:43 +02:00
Bram Matthys 0d2d4d5bca Rename match() and _match() to match_simple() -AND- invert the return value
of match_simple() and match_esc(). So, developers, be aware, this is how
you should use the function in a correct way:
if (match_simple("*fun*", str))
    printf("It was fun\n");

Rationale:
I've always been annoyed by the inversed logic, even though it was similar
to strcmp. So I've reverted it.
I could have chosen to maintain match() rather than this match_simple()
name, but this way I force (3rd party module) devs to update their function,
while otherwise everything would mysteriously fail due to the inverted logic.
2019-08-17 09:20:49 +02:00
Bram Matthys e1fcc3a667 Rename match() and _match() both to match_simple()
and get rid of the "bahamut optimized version".
Stage 1 of 2.
2019-08-17 09:15:34 +02:00
Bram Matthys c01c9248f5 Revert e428c77c47 (only to try again later) 2019-08-17 09:05:09 +02:00
Bram Matthys e428c77c47 match() -> match_nuh() and _match -> match_simple() 2019-08-17 08:56:18 +02:00
Bram Matthys a408b61f32 For some unknown reason del_ListItem() iterated the entire list. Weird. 2019-08-16 17:36:15 +02:00
Bram Matthys 3a454e3eb3 free_mtags() -> free_message_tags() 2019-08-16 14:54:28 +02:00
Bram Matthys ced8b0935d Check for and refuse to run with <2048 bits RSA keys. I hope nobody is
using 1024 bit RSA keys in 2019, but always better to check and inform
the admin about such a big mistake.
2019-08-15 08:52:28 +02:00
Bram Matthys 7fa2b8be05 More ssl -> tls moves. Also recommend to use 'certfp' rather than
the longer 'sslcertfp' or 'tlscertfp', we already support this since
4.0 so... updated the documentation as well.
2019-08-12 14:53:29 +02:00
Bram Matthys 09cf485d6c Mass rename of "ssl" to "tls" everywhere. Including conf/ssl to
conf/tls. If you are upgrading then conf/ssl will be renamed to
conf/tls and a symlink will be added (so certbot etc won't fail).
This is part 1...
2019-08-12 14:26:31 +02:00
Bram Matthys 25687c2bed New efuncs: tkl_ip_hash() and tkl_ip_hash_type(), for the rmtkl module. 2019-08-11 14:48:07 +02:00
Bram Matthys 806256e9c2 Move generate_batch_id() to core. Use chathistory BATCH type, if supported. 2019-07-13 15:25:56 +02:00
i 60ebc1375e Support channel status prefixes for SAJOIN. 2019-07-10 17:42:46 +03:00
Bram Matthys d09b9d53a4 Make SSL/TLS mandatory for UnrealIRCd to run. Previously you could get
around this by simply having no certs etc. I doubt anyone used it and
that was not a recommended configuration.
(More to come)
2019-07-09 20:06:11 +02:00
Bram Matthys b605b7fd86 Use delayed module unloading not only for modules with moddata but also
for modules which have extended channelmodes with parameters,
since they have the same problem.
2019-06-29 09:10:18 +02:00
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...
2019-06-28 22:08:45 +02:00
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 2a7fc8042d Add new moddata types: MODDATA_LOCALVAR and MODDATA_GLOBALVAR. Untested.
Code using it will soon follow (and then it will be tested :D)
2019-06-28 18:35:37 +02:00
Bram Matthys c673e5bbc6 Get rid of now meaningless include/hash.h 2019-06-26 17:17:20 +02:00
Bram Matthys ded4a65a60 u_int16_t -> uint16_t and u_int32_t -> uint32_t, remove typedefs for
these types and others, that should no longer be needed thanks to
stdint.h.
2019-06-26 17:06:46 +02:00
Bram Matthys 709c84fff9 Remove stupid hash table layer for channels that only eats 256k+ extra
memory and causes unnecessary slowdown. Stupid ->hits and ->links.
And get rid of "return (xyz)", must be "return xyz" :D
2019-06-26 16:56:17 +02:00
Bram Matthys f1b0b6b76e Make throttling code (connect-flood) use SipHash and increase the
hash table size from 1019 to 8192 to have fewer collisions.
2019-06-26 16:46:28 +02:00
Bram Matthys f6eac29592 hash_nick_name -> hash_client_name, hash_find_nickserver -> hash_find_nickatserver
Both were confusing :)
2019-06-26 13:45:55 +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 f9b589d0c6 Remove almost 1000 lines, all functions that are (now) unused.
Also, drop support for snomasks to non-ircops (TODO: more)
2019-06-22 19:32:11 +02:00
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 05202dd2a4 Move can_send() function from core to m_message. 2019-06-22 16:03:06 +02:00
Bram Matthys be49ef0bb8 More extban API changes... fun... 2019-06-22 15:11:16 +02:00
Bram Matthys 086d370704 Change extban API: pass 'msg' in BANCHK_MSG and (new) BANCHK_LEAVE_MSG. 2019-06-17 20:19:34 +02:00
