Bram Matthys fcc7a2cf06 Channel mode +d is local, so should be tagged as such. 2021-06-19 17:03:26 +02:00
Bram Matthys dd1f572acb The code for -d (so after -D+d) never took QUITs into account. Fun. 2021-06-19 16:59:54 +02:00
Bram Matthys a541b8f4ad Add support for OpenSSL 3.0.0 (based on -beta1)
Now compiles fine without any warnings.

Note that certificate_quality_check() is an outstanding TODO item.

Bram Matthys 991f9f347e Allow wildcards in ~a extban, also special code for ~a:0 and ~a:*
~a:0: match all unauthenticated users
~a:*: match all authenticated users
~a:SomeUser: match only SomeUser, also allow wildcards here, even
though that is usually a very bad idea :D

Bram Matthys b72ea1d945 Change allow block to use allow::mask instead of allow::ip / allow::hostname
We use 'mask' everywhere in the config except here, which is annoying
and also inflexible since mask has several nice options, see
https://www.unrealircd.org/docs/Mask_item

Users upgrading will receive a warning, and a reference to
https://www.unrealircd.org/docs/FAQ#allow-mask
but the IRCd will continue to boot (it is not an error).

Ramiro Bou 5d6738b3e8 Allowing multiple masks in "deny link" blocks. (#140) 2021-06-18 15:13:50 +02:00
Bram Matthys fb8c7a5a75 Fix weird behavior for users in pre-connect stage, eg showing
up in WHOIS. Reported by armyn and Valware.
2021-06-15 20:26:12 +02:00
Bram Matthys 8a655b8bb4 Fix spamfilter not working with type 'c'.
If you had a spamfilter on type 'c' but not on 'p' then it would not
trigger. Reported by armyn in https://bugs.unrealircd.org/view.php?id=5913
This probably went unnoticed because most people add spamfilters
on 'pc' (or even 'pcnN').

Bram Matthys 572b349cbd set::restrict-commands: new option exempt-tls which allows SSL/TLS users
to bypass a restriction.

Bram Matthys 389a971f96 Fix rapid autoconnect protection to work with >120 servers (:D) 2021-06-07 17:11:20 +02:00
Bram Matthys 36097fbdce Fix SQUIT being sent back to where it came from.
Reported by Ariadne Conill in https://bugs.unrealircd.org/view.php?id=5906

This patch applies cleanly against 5.2.0-rc1 and 5.0.9.x.

Needs more testing, though, as fiddling with SQUIT code and the
various directions and far/near server distinctions can be tricky.
2021-06-07 10:22:23 +02:00
Bram Matthys 5237ebaabc Fix crash in 5.2.0-rc1: don't call flood_limit_exceeded_log() if a remote
server causes the target flood protection limit to be hit for a target
user or a channel.
2021-06-07 07:48:03 +02:00
Bram Matthys 3188b7be2d Small code cleanup for two efuncs, so the names match. 2021-06-06 08:33:20 +02:00
Bram Matthys f6c2b93c72 Show how many sockets/clients the server can handle in 'STATS S'.
Suggested by westor in https://bugs.unrealircd.org/view.php?id=5838

This also fixes a bug where output from modules for 'STATS S' was
shown twice (eg: modef-default-unsettime shown twice).
2021-06-04 10:09:28 +02:00
Bram Matthys 5acef88ceb All violatons of target-flood, nick-flood, join-flood, away-flood,
invite-flood, knock-flood, max-concurrent-conversations are now
reported to opers with the snomask 'f' (flood).
2021-05-30 19:10:18 +02:00
Bram Matthys 6f92233919 The set:anti-flood block has been redone so you can have different limits
for "unknown-users" and "known-users".
As a reminder, by default, "known-users" are users who are identified
to services OR are on an IP that has been connected for over 2 hours
in the past X days.
See https://www.unrealircd.org/docs/FAQ#new-anti-flood-block
for more information on the layout of the new block.

NOTE: This actual feature, the relase notes and the documentation
      are all work in progress.
2021-05-30 18:45:27 +02:00
Bram Matthys 79ded54df1 Make join-flood use the new framework too, well... partially anyway. 2021-05-28 18:08:07 +02:00
Bram Matthys 36b9faa7cd Code cleanup: move flood control to generic system 2021-05-28 17:59:39 +02:00
Bram Matthys 3e1f092afc Rename FLD_* to CHFDL_* in chanmodes/floodprot.c, so it does
not clash with future stuff.
2021-05-28 15:48:54 +02:00
Bram Matthys 191990b881 Code cleanup: at some places "ClientUser" was used instead of "User". 2021-05-28 15:26:58 +02:00
Bram Matthys 78ca5ecc3e Add "draft/bot" message tag to messages from +B clients.
As mentioned in https://ircv3.net/specs/extensions/bot-mode

2021-05-28 10:07:26 +02:00
Bram Matthys 845a582d76 Add support for +draft/reply and load the module by default.
See https://ircv3.net/specs/client-tags/reply for the draft.

Can be used by clients to indicate to which message they are writing
a reply. This can be especially useful for bots, to indicate that
a response belongs to a user request, eg a !trigger.
2021-05-28 09:14:40 +02:00
Bram Matthys a85a38e69d Add the ability to SPAMFILTER message-tags.
The new target type is called 'T' and we match against "name=value"
of each message tag (or just "name" if it is without value).

Example: SPAMFILTER ADD -simple T kill 0 this_is_a_test +typing=active
(No this is not a suggestion :D)

This probably won't be used much at all, but it is good to have the
option available in case there is some massive problem,
especially since more message tags may pop up sooner or later.

Caveat: this is actually a bit slow as we may have to check multiple
message tags for a single line.
If there are zero message-tag spamfilters then we will automatically
short-circuit and save all this CPU, which will be the most common case.

Bram Matthys 264ed614fc Implement Sec-WebSocket-Accept from

Bram Matthys 872aa93635 Move some string helpers to src/misc.c
skip_whitespace() and read_until()
2021-05-24 18:32:57 +02:00
Bram Matthys cd9ac916de Allow setting set::history::channel::playback-on-join::lines to zero
in case you want to disable this feature.

Note that clients that are using CHATHISTORY will already no longer
receive history-on-join ("push") since they REQ a CAP that will inhibit
this and they will "pull" the history instead when they want/need to.

So... this option is really only there if you want to disable it for
non-CHATHISTORY-clients.

Bram Matthys 842e06d7d3 Possibly fix small memory leak. 2021-05-23 13:59:57 +02:00
Bram Matthys 92b9fa07a1 Make history backend non-PERM so it can be upgraded on the fly.
Tested:
* Rehashing and sending messages before after (multiple times)
* Terminating
* Unloading by commenting out
2021-05-23 13:56:03 +02:00
Bram Matthys 88d7829e5b Allow lower set::restrict-commands::xyz::connect-delay values.

Bram Matthys 9c0710a9a4 Adjust +H setting if a channel goes -r and had a high setting
that was only allowed for registered channels (+r).
2021-05-23 09:26:38 +02:00
Bram Matthys 3ad6878865 Set new maximums for channel mode +H. If the channel is +r then the maximum
is now 5000 lines / 31 days. For unregistered it is 200 lines / 31 days.
Previous setting was 200 lines / 7 days for both.

Admins can tweak these settings, see:
https://www.unrealircd.org/docs/Set_block#set::history

More code to deal with corner issues will follow later.

UnrealIRCd module coders [!]:
This also changes the channel mode API conv_param. You can use
the UNREAL_VERSION_TIME >= 202120 condition to detect this.
Eg:
 #if UNREAL_VERSION_TIME < 202120
 int my_conv_param(char *para, Client *client);
 #else
 int my_conv_param(char *para, Client *client, Channel *channel);
 #endif

Bram Matthys 8431cd43b2 Fix read-after-free 2021-05-22 14:59:54 +02:00
Bram Matthys c0b86c757c Change chanmode +H parameter to show hours and days when needed and
possible if it rounds off nicely, eg +H 100:7d. Note that the
existing syntax is still accepted, eg +H 20:1440 and +H 20:1440m
are both converted to 20:1d.

With potentially higher time values this change makes the mode
parameter a lot more readable.

Support for translating timevalues is already in UnrealIRCd 5.0.2
and higher, so should be fine for nearly everyone.
2021-05-22 14:49:25 +02:00
Bram Matthys c6873292b9 Implement CHATHISTORY TARGETS...
Except that it still needs to order the result by timestamp,
which it does not do at the moment.

Bram Matthys 188dc7792d Fix crash on remote CHATHISTORY cmd (by servers/services). 2021-05-21 07:20:26 +02:00
Bram Matthys cda145b62a Add initial version of CHATHISTORY command
from https://ircv3.net/specs/extensions/chathistory

Current status of the module in UnrealIRCd:
* A significant part of this is done and working
* Currently in modules.optional.conf to get test exposure,
  not yet loaded by default.
* CHATHISTORY subcommands implemented: BEFORE, AFTER, LATEST, AROUND
* It does not implement the subcommand "BETWEEN" yet
* It does not announce or recognize the (draft) CAP's yet
* It does not announce the ISUPPORT token CHATHISTORY=xx yet
* Testcases need to be written to validate everything
* There will be bugs, now, and also while implementing the rest
  in the days to come.

Bram Matthys 8c71cd1a65 * Make channeldb write the db on terminate
* Fix channel history issues with writing on terminate
* Change tkldb and reputation to only write the db
  on terminate and not on every REHASH anymore

..all this thanks to the new loop.ircd_terminating, so modules can
see the difference between regular rehash and terminating.

Bram Matthys ae873ab25a Compile fixes for Windows 2021-05-16 19:15:01 +02:00
Bram Matthys f79fec62f1 Add CAP unrealircd.org/history-backend which declares the policy/
configuration on how history is stored (in memory and/or on disk).
This is similar to other disclosing policies like
unrealircd.org/link-security and unrealircd.org/plaintext-policy.
The reason for this cap (and similarly the other caps) is that
the user can make an informed decision on whether it finds the
policy/safety/privacy of an acceptable level or not.

Fixes for turning persist on/off on the fly (REHASH)

Make release notes a bit more clear.
