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 1f47cc7824 Support for dated log files such as log "ircd.%Y-%m-%d.log" { }
Suggested by Amiga600 in https://bugs.unrealircd.org/view.php?id=5784

This also fixes a bug with log::maxsize on Windows (cannot overwrite
existing file with .old).

It simplifies the logging code a little and makes it a tad more readable.

And it adds an unreal_strftime() function to make things easy.

Bram Matthys 1baf5f9f7d Show reputation score and some other info in "Client connecting"
notices to IRCOps and in ircd.log.
See the release notes for more details.

Module coders:
You can use HOOKTYPE_CONNECT_EXTINFO to add your own additional
information as well. See get_connect_extinfo() for inspiration.
Use nvplist_add() or nvplist_add_fmt() to easily add your info
to the list.

Module coders II:
Small note: this moves the sending of the far connect notice
to /under/ HOOKTYPE_REMOTE_CONNECT instead of /above/.

Bram Matthys 9204939a7f Windows: improve logging on-boot, especially when running as a service.
When booting no log files are open yet as we have not parsed any log { }
entries yet. On *NIX we log to stderr during that stage.
On Windows it varies: when running in GUI mode we save the log to a
buffer and display it after booting in a dialog.
When running as a service on Windows we previously wrote SOME entries
to service.log, but other entries were not logged or shown anywhere.

This makes both GUI and Service-mode on windows log all ircd_log()
calls with LOG_ERROR, instead of only config_status(), config_warn()
and config_error() messages.

This also removes config_progress() which isn't used by anything.

Oh, and it also fixes a memory leak in the Windows boot code, a leak
that nobody would have noticed anyway, but still.

Bram Matthys b5a205f4f3 Fix /SQUIT for server 2 hops away not working correctly.
Reported by k4be in https://bugs.unrealircd.org/view.php?id=5539
2020-01-31 12:15:36 +01:00
Bram Matthys c9feaa0b15 Fix : at beginning of gecos being dropped off in intra-WHOIS.
This does NOT "fix" https://bugs.unrealircd.org/view.php?id=5538:
WHOIS nick
:localserver.example.com 311 test nick ident host * :realname
WHOIS nick nick
:remoteserver.example.com 311 test nick ident host * realname
.. because your IRC protocol parser should not care about a :
or a lack of :. For text not containing spaces nor :-prefix there
is no difference in meaning and it should parse to the same.

However, this DOES fix an issue if the realname itself started
with a colon, such as "USER x x x ::something":
WHOIS nick
:localserver.example.com 311 test nick ident host * ::something
WHOIS nick nick
:remoteserver.example.com 311 test nick ident host * :something
.. because that does not have the same meaning and is a real
incorrect drop of a character.
Yeah, I took into account spaces, but not a word starting with :, my bad.

Bram Matthys 86ce42103a Make the 'silence' module optional. Suggested by westor in

Bram Matthys 798f502875 Mass change (at least this one could be fully automated): 'chptr' -> 'channel'
to be consistent with the 'sptr' -> 'client' rename earlier.
2019-10-05 08:49:10 +02:00
Bram Matthys 3a64077f51 Use 'client' everywhere (if there is no confusion) instead of 'sptr' or 'cptr'.
This so I - and others - don't constantly have to wonder whether the client
is called sptr, cptr or acptr in a simple routine.
Insane --> 212 files changed, 6814 insertions(+), 6945 deletions(-)
Couldn't just mass-replace of course since there are places where there
are multiple clients involved. So had to check each function.
Also renamed some 'acptr' to 'target' and such.

I will write a page with new style rules later.. but in short if there is
only 1 client involved it will now be called 'client'.
2019-10-04 15:25:35 +02:00
Bram Matthys 3d5e49e701 Get rid of FLUSH_BUFFER, since we no longer signal things that way.
Merge check_init and AllowClient into one single AllowClient()
and make it use the more logic 1 and 0 return values for allow / deny.
Similarly, use logic 1 / 0 return values for verify_link.

Module coders:
HOOKTYPE_CHECK_INIT and HOOKTYPE_PRE_LOCAL_CONNECT, changed the
return value, you should now use HOOK_*, eg HOOK_DENY to stop
processing (eg client killed).
2019-10-04 12:30:51 +02:00
Bram Matthys 92df36a87f Return values of various functions changed, in particular the ones
that deal with finding TKL's or spamfilters etc.
More will likely follow, to make things more logical.
Also, run_spamfilter -> match_spamfilter
place_host_ban, can_privmsg, check_dcc, find_tkline_match all impacted.
2019-10-04 11:30:27 +02:00
Bram Matthys 3126a3fae4 BIG changes internally that will break all modules and required many
code changes in UnrealIRCd itself:
1) Clients are no longer freed directly by exit_client. Most fields
   are freed, but 'sptr' itself is not, so you can use IsDead() on it.
2) exit_client now returns void rather than int
3) ALL command functions return void rather than int.
   Of course this also affects do_cmd, command overrides, etc.

This is a direct consequence of the removal of 'cptr' earlier, as that
was used to signal certain things that are now no longer possible
(and it raises the question if things were always correctly signaled
in the first place, so may fix some bugs).
It also makes the code more resillient against cases where you forgot
to check if the client was freed. Still, you are encouraged to do an
IsDead(sptr) if you are calling functions that may kill clients,
such as command functions or things that may use spamfilter.

More changes will follow, such as the removal of FLUSH_BUFFER.
2019-10-04 10:28:41 +02:00
Bram Matthys ab3feff7c2 exit_client() now takes 3 parameters rather than 5:
** Exit this IRC client, and all the dependents (users, servers) if this is a server.
* @param sptr        The client to exit.
* @param recv_mtags  Message tags to use as a base (if any).
* @param comment     The (s)quit message
* @returns FLUSH_BUFFER is returned if a local client disconnects,
*          otherwise 0 is returned. This so it can be used from
*          command functions like: return exit_client(sptr, ....);

Also clean up a bit.
2019-09-15 11:33:17 +02:00
Bram Matthys edb199841a Move all the (remaining) LIST stuff to modules/list and use ModData. 2019-09-15 11:07:15 +02:00
Bram Matthys ffe5abe30b ModData: moddata_localvar -> moddata_local_variable,
moddata_globalvar -> moddata_global_variable,
and the just-added moddata_localclient -> moddata_local_client
..all this so it's more consistent
2019-09-15 09:47:54 +02:00
Bram Matthys b2f32c1746 Add moddata_localclient(), which is for locally connected clients only.
Make the silence module use this.
2019-09-15 09:26:54 +02:00
Bram Matthys 654919f2c4 Make modules/silence use ModData and remove more out of the core.
It uses a Silence struct now, rather than Link.
Also, SILENCE is handled only for local clients now (different
cost/benefit tradeoff nowadays).
2019-09-15 09:03:30 +02:00
Bram Matthys 9fc1e758ab Mass change of dst = strdup(str) to safe_strdup(dst,str) but with a manual
audit since 'dst' must now be initialized memory.
There's still a raw_strdup() if you insist.

This is step 2 of X of memory allocation changes
2019-09-14 16:58:01 +02:00
Bram Matthys de87b439b7 Update memory allocation routines. Step 1 of X. 2019-09-14 16:52:53 +02:00
Bram Matthys baf02e8980 Rename all m_* functions to cmd_* functions. 2019-09-13 15:45:19 +02:00
Bram Matthys bf2c5110db IsPerson() -> IsUser(), MyClient() -> MyUser(), etc.
This so we have a few simple concepts:
Client: this can be a user, server, or something unknown yet
Then the type of clients:
User: this is a user, someone with a nick name.
Server: this is a server
Etc.
