Bram Matthys f1f0acdd25 ident_lookup: reject spaces and control characters early.
...even though in m_nick there is code so it never gets into
sptr->user->username.
2019-09-13 19:37:28 +02:00
Bram Matthys 9b14970c2a Move ident lookups to module 'ident_lookup' and rewrite the code
to be a bit less ugly. The module is loaded by default so you can
still use set::options::identd-check like before, even though I
hate ident... it's old shit... still, other's seem to like it.

More changes will follow later. There is still some ident stuff
in the core at the moment and the module is currently PERM, which
largely (but not entirely) defeats the purpose of being a module.
That will be fixed at a later time as well.

Bram Matthys 3592d8db3a Update name in first few lines of .c files.
Eg: src/modules/m_away.c is src/modules/away.c nowadays.

Bram Matthys baf02e8980 Rename all m_* functions to cmd_* functions. 2019-09-13 15:45:19 +02:00
Bram Matthys bb1bb35f50 MOD_LOAD(xyz) is now just MOD_LOAD(), same for MOD_TEST, MOD_INIT,
MOD_UNLOAD. And MOD_HEADER(xyz) is now MOD_HEADER even without ()
since this isn't a function, really.
To make things understandable I added the following to the
developer section of the release notes:

* The module header is now as follows:
  ModuleHeader MOD_HEADER
    = {
          "nameofmodule",
          "5.0",
          "Some description",
          "Name of Author",
          "unrealircd-5",
      };
  There's a new author field, the version must start with a digit,
  and also the name of the module must match the loadmodule name.
  So for example third/funmod must also be named third/funmod.
* The MOD_TEST, MOD_INIT, MOD_LOAD and MOD_UNLOAD functions no longer
  take a name argument. So: MOD_INIT(mymod) is now MOD_INIT()
2019-09-13 15:27:40 +02:00
Bram Matthys 9114c0ed85 The name of the module must now match the relative path, e.g.
the chanmodes/delayjoin module must be named chanmodes/delayjoin
in the module header.
This because currently we have two module names for each module,
one is the name from the MOD_HEADER and the other is the
relative path, such as used by loadmodule and is_module_loaded().

This commit also (not entirely, but practically) breaks loading
of modules outside the regular modules path. I don't think that's
a problem, although it could use a bit more documentation.

GottemHams 43b03e75a6 Fixed some now-outdated comments in require-module, also send deny module notices globally instead of locally and change the default message for this 2019-09-12 21:45:33 +02:00
GottemHams ab7cdbf2a7 Fix a couple of bugs recently introduced in require-module, also delay SQUITting until after the current SMOD command has been parsed 2019-09-12 19:48:33 +02:00
Bram Matthys 70410b3f33 Remove unused variables (67 files done, will do rest another time). 2019-09-12 17:57:01 +02:00
Bram Matthys 8d2dad4796 chanmodes/floodprot: remove old +f 1:1 conversion code, cleanup a bit
and remove unused variables (unused now, that is).
2019-09-12 16:49:20 +02:00
Bram Matthys c3f7bbd9c0 require-mode: account for a little bit more room in S2S command
(not just hostname but also the command "SMOD" etc.. let's just say
16 bytes for now)
..and some minor cleanups of variables that are not needed.
2019-09-12 07:55:34 +02:00
Bram Matthys cafe3cfd6d Some S2S command changes to new require-modules module:
REQMODS Gmodname:version ....
to:
SMOD G:modname:version ....
Also, call the module require-module to be consistent with the
naming of the configuration directive.
Not sure yet of the set name, but call it set::require-module for
now as well.

Bram Matthys 88cbc38ff2 Do some more syntax checking, even for servers.
This fixes a crash in case of incorrect server to server traffic.

Bram Matthys 482c85de44 Get rid of this sptr->serv->user, as we already have sptr->serv->by
to track who initiated the connect. It also didn't seem to be displayed
anywhere but in /TRACE.
2019-09-11 19:46:52 +02:00
Bram Matthys 9b113c27e4 Document some more structs and group them in a logical place. 2019-09-11 19:07:11 +02:00
Bram Matthys c72d848b61 Get rid of MembershipL since there's no difference anymore between
local membership structs (MembershipL) and remote ones (Membership),
so they are now all called... Membership.
2019-09-11 17:53:29 +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.
2019-09-11 17:43:17 +02:00
Bram Matthys fcf0ff4e3c Document client statuses (cptr->status) and some more renames. 2019-09-11 16:52:11 +02:00
Bram Matthys 2df5326615 Overhaul of all client flag macros (mass renaming, always use getters/setters/checkers) 2019-09-11 16:00:47 +02:00
Bram Matthys e372e9118d Move cptr->count to cptr->local->identbufcnt since this only used by
the ident reading code nowadays, which obviously only happens for
locally connected users.
2019-09-11 14:36:12 +02:00
Bram Matthys d80e601760 Rename sptr->username to sptr->ident, since that is what it is.
[skip ci]
2019-09-11 14:31:14 +02:00
Bram Matthys c69bdbe175 ->status is now an enum of ClientStatus and STAT_xx -> CLIENT_STATUS_xx 2019-09-11 14:27:32 +02:00
Bram Matthys 792709bf4f Move cptr->fd to cptr->local->fd. This may cause some crashes while
the rest of the code is audited / checked ;)
2019-09-11 14:21:07 +02:00
Bram Matthys cb236eea88 Rename cptr->from to cptr->direction, since the 'from' is rather misleading
as cptr->from is NOT (necessarily) the server where cptr is connected to.
So we now call it cptr->direction since it indicates the directly connected
server (or &me)... in other words: the direction of the client path.
2019-09-11 14:03:27 +02:00
Bram Matthys 6a019d6188 Let's allow user connections.
*sigh*
(at least we have automated tests for this)
2019-09-11 13:44:55 +02:00
Bram Matthys 1e6a3bdd55 Bump PASSWDLEN to something "large enough for everyone" (256) rather than current (48). 2019-09-11 13:27:45 +02:00
Bram Matthys 786054e6b7 Remove 'md5', 'sha1' and 'ripemd160' from auth code. These are insecure and
old authentication types that are already deprecated in UnrealIRCd 4.x.
They don't contain any rounds which means they can be cracked at a rate of
millions per second. Use the secure hashing type 'argon2' instead
(or, if you must, use the less secure 'bcrypt' type).
2019-09-11 13:17:28 +02:00
Bram Matthys 04607f5b1a Various auth cleanups: Auth_Check() now returns 1 on allow and 0 on deny (!)
to keep things simple, rather than having 4 different return values
(yes.. FOUR!).
[skip ci]
2019-09-11 13:10:15 +02:00
Bram Matthys 05e776fb71 More cleanups: now mostly auth-related: use better names and use enums
for authentication types. Rename Auth_Make to Auth_Hash. Add docs. etc.
2019-09-11 12:37:34 +02:00
Bram Matthys e8d53ffe8e And more type changes to make things consistent and more readable. 2019-09-11 11:04:31 +02:00
Bram Matthys 2a5ea10453 Lots of changes again. Most notable: Cmdoverride -> CommandOverride,
including things like CallCmdoverride() to CallCommandOverride().
Type changes like aTKline -> TKL and many more (in particular
aSomething to Something etc. such as aWatch to Watch) but these are
less used by 3rd party module coders.
2019-09-11 10:20:00 +02:00
Bram Matthys f55682cbaa More (typedef) struct name changes. Mostly configuration but also
aCommand to RealCommand. Although not sure if this latter makes
things a lot more descriptive :D. Can revisit later.
(more to follow)
2019-09-11 10:04:47 +02:00
Bram Matthys 23116d344a Give structs the same name as the typedefs. Rename aClient to Client,
aChannel to Channel, and some more. Third party module coders will
love this. But.. it makes things more logical and the doxygen output
will look more clean and logical as well.
(More changes will follow)

GottemHams fbd7ff1f5a Implemented set::min-nick-length (default 0 aka no minimum required) and added a line for it to /stats S, as a bonus my editor strips trailing whitespace :D 2019-09-09 20:33:38 +02:00

Bram Matthys 90d39d4665 tkldb module: Turn a few config_error() into config_warn() since
we continue, while errors mean we would fail to boot (or fail to rehash)
which is not the case.

Bram Matthys 0c4502bf79 Define and use SIPHASH_KEY_LENGTH rather than some magic value. 2019-09-08 14:15:23 +02:00
Bram Matthys ebd9c738f2 Some cleanup/rewrites of 'r' (repeat) in the floodprot module (+f).
Use a more simple hashing algorithm and one that uses 64 bits,
don't allocate any memory dynamically, just use an int64_t.
Also, only do the hashing if 'r' is actually enabled in +f
on the channel, as otherwise it's pointless.
