* add general matching framework (aMatch type, unreal_match_xxx functions)
* change spamfilter { } block syntax
* add support for simple wildcard matching (non-regex, just '?' and '*')
This is the initial commit so the new lib is not in yet, 'regex' is not
functional (but 'posix' and 'simple' are working), linking has not been
fully tested and no warnings are printed yet. IOTW: work in progress!
This is technically in violation of RFC1459, however the general consensus
at the IRC3 discussion meetings is that it's the numeric which actually matters.
This allows the IRCd to enforce MLOCKs that are set by services, which
eliminates clashes between users setting modes and services enforcing
it's mlock on channels. (#3055)
having to use a special SSL-only port, they can simply switch to SSL on
any port. This is currently only supported by few clients (such as KVIrc 4).
This functionality can be disabled by setting set::ssl::options::no-starttls,
for example if you don't want to offer SSL to your users and only want it
to be used for server to server links.
Naturally, the IRCd must be compiled with SSL support for STARTTLS to work.
- Fixed SSL_ERROR_WANT_READ in IRCd_ssl_write()
This new feature (away notify) is announced in 005 (ISUPPORT) as: WATCHOPTS=A
Format is: WATCH A +UserOne +UserTwo
New numerics to cope with away notification in WATCH are:
RPL_NOWISAWAY: to indicate the user is away _when adding_ it to WATCH list
RPL_GONEAWAY: user was not away, but is now
RPL_NOTAWAY: user was away, but is no longer away
RPL_NOWISAWAY: user was away, and still is, but the reason changed
Example:
WATCH A +Target
Request to add user 'Target' to the watch list with away notification
:maintest.test.net 609 MySelf Target ~blih test.testnet 1204309588 :not here atm
Reply to watch add: user is online and away, reason is provided
:maintest.test.net 599 MySelf Target ~blih test.testnet 1204309588 :is no longer away
User is back (no longer away)
:maintest.test.net 598 MySelf Target ~blih test.testnet 1204309722 :lunch
State change: user is now away, reason is provided
:maintest.test.net 597 MySelf Target ~blih test.testnet 1204309738 :shopping, bbl
User is still away, but reason changed.
The syntax for each numeric is:
<nickname> <username> <hostname> <awaysince> :<away reason>
In case of 599 (RPL_NOTAWAY) it is:
<nickname> <username> <hostname> <awaysince> :is no longer away
For the record, this is all based on a draft from codemastr from 2004, which was
implemented in Unreal3.3 (devel branch) in 2006. Today, in 2008 it was updated
with away reason support and backported to Unreal3.2. Because away notification
hasn't been used until now (due to it only being in Unreal3.3) we felt it was
safe to break some numerics.
It also sends a numeric to the user saying the command has been processed, but a copy
has been sent to ircops. I feel this is a good idea for privacy reasons (anti-spy),
though I don't know how users will react to this. If you are using this on your network
and get users bothering you about it (or before that ;p), it's probably a good idea
to explain it somewhere on your site or FAQ :).
Example usage:
/spamfilter add p warn - Testing_mirc_decode_filter \$decode\(.*\)
[WARNING] The numeric text is likely to change in the next few weeks (early-cvs-commit).
- If a class block was removed and any other blocks would be referencing the class block
(such as: allow::class, oper::class, link::class), then this would cause a crash.
Reported by Mike_ (#0002646).
throttle the number of joins per-user to X in Y seconds. Idea from Angrywolf (who
wrote a module that did this before). This might need some more testing :).
It's enabled by default but can be #undef'ed in include/config.h (line 449).
- Numeric audit: 15 small changes (int/long mismatches etc). This might have fixed some
bugs on architectures where 'long' and 'int' have different sizes (eg: opteron).
- Module coders: if CmdoverrideAdd() is called for an override that is already in place, it
now sets MODERR_EXISTS as errorcode and returns NULL (previously it added duplicates).
In the past module coders had many issues with PERM mods... you had to use weird tricks,
but now you can (and should!) just override on INIT and on HOOKTYPE_REHASH_COMPLETE.
- Moved register_user declaration to h.h, updated call in m_pingpong.c (due new 'ip' field).
- Usermode +v ('receive dcc send rejection notices') is oper-only now for privacy reasons.
- Added dcc allow { }, which allows one to make exceptions over deny dcc { }.
- Added deny dcc::soft and allow dcc::soft item, if set to 'yes' it allows someone
to explicitly override it per-person via /DCCALLOW (see next).
- Added DCCALLOW system, taken directly from bahamut.
With this system you can block certain (or all) DCC SENDs and then allow the user to
'override' this limit for every user he/she trusts via '/DCCALLOW +User'.
This is an attempt to stop (or at least limit) the spreading of viruses/etc.
See '/DCCALLOW HELP' for more info.
- Added example dccallow.conf which filters everything except some known
'safe types' (jpg, jpeg, png, gif, etc). Note that the purpose of this file
is NOT to get a complete list, rather to limit it to a few 'known safe' entries.
- Added set::maxdccallow: max number of entries of the DCCALLOW list (default: 10).
- Fixed a few wrong macro's (ircstrdup/ircfree) in s_conf.c causing
very weird behavior... This also fixes a bug where set::spamfilter::ban-reason
would have the value of ban-time.
- Improved spamfilter again.
- The new syntax is:
/spamfilter [what] [type] [action] [tkltime] [reason] [regex]
[tkltime] specifies the duration of any *lines placed by this rule.
[reason] specifies the *line, kill and/or block reason.. no spaces
allowed, but '_' will be escaped to a space.
In both cases you can simply use '-' to skip and use the default.
Ex: /spamfilter add p block - - Come watch me on my webcam
/spamfilter add p gline 3h Please_go_to_www.viruscan.xx/
nicepage/virus=blah Come watch me on my webcam
- A message is now shown if the msg/notice/dcc is blocked.
- There are 2 new spamfilter action types:
'dccblock' will mark the user so (s)he's unable to send any files by DCC.
'viruschan' will part the user from all channels and join
set::spamfilter::virus-help-channel (default: #help).
this action might be improved to do more later.
- Internal: added EXTTKL PROTOCTL, this determinates if 10 parameters
instead of 8 are supported for m_tkl (used by spamfilter add).
This new system needs some testing... :)
