mysterious error 'The specified module could not be found' even though the
file exists. This usually means that it depends on another DLL, but
apparently Microsoft decided not to mention that in the error message.
We now append some small text when such an error happens, saying that it
could be because of a missing dependency. Reported by Phil.
- IPv6: it seems some recent Linux dists decided to make IPv6 sockets
IPv6-only, instead of accepting both IPv4&IPv6 on them like until now.
FreeBSD (and other *BSD's) already did that move a few years back,
requiring server admins to sysctl.
We now make use of a new option to explicitly disable "IPv6-only".
This should work fine on Linux.
Whether it provides a complete solution for FreeBSD, I don't know, testing
is welcome! In theory setting net.inet6.ip6.v6only to 0 should no longer
be needed, but you might still need to enable ipv6_ipv4mapping.
- Fix stupid issue where current CVS would no longer link TO an earlier
Unreal server (eg: outgoing connect to a 3.2.8 hub). Reported by ohnobinki
(#0003901).
- Server protocol: added PROTOCTL EATH=servername, which allows us to
authenticate the server very early in the handshake process. That way,
certain commands and PROTOCTL tokens can 'trust' the server.
See doc/technical/protoctl.txt for details.
- Server protocol: between new Unreal servers we now do the handshake a
little bit different, so it waits with sending the SERVER command until
the first PROTOCTL is received. Needed for next.
- Server protocol: added PROTOCTL SERVERS=1,2,3,4,etc by which a server can
inform the other server which servers (server numeric, actually) it has
linked. See doc/technical/protoctl.txt and next for details.
- When our server was trying to link to some server, and at the same time
another server was also trying to link with us, this would lead to a
server collision: the server would link (twice) ok at first, but then a
second later or so both would quit with 'Server Exists' with quite some
mess as a result. This isn't unique to Unreal, btw.
This happened more often when you had a low connfreq in your link blocks
(aka: quick reconnects), or had multiple hubs on autoconnect (with same
connfreq), or when you (re)started all servers at the same time.
This should now be solved by a new server handshake design, which detects
this race condition and solves it by closing one of the two (or more)
connections to avoid the issue.
This also means that it should now be safe to have multiple hubs with low
connfreq's (eg: 10s) without risking that your network falls apart.
This new server handshake (protocol updates, etc) was actually quite some
work, especially for something that only happened sporadically. I felt it
was needed though, because (re)linking stability is extremely important.
This new feature/design/fix requires extensive testing.
This feature can be disabled by: set { new-linking-protocol 0; };
user target string (nick!user@host:info), insteaf of doing it at like 5 places.
- Spamfilter target 'u' (user): the host field (nick!user@HOST:realname) is now escaped
with brackets if it's an IPv6 address, eg: blah!blah@[1:2:3:4:5:6:7:8]:hello, reported
by aquanight and others (#0003010).
map the command '/BLAH 5' to 'NICK idiot5'. More info in docs on alias block.
- Modulized: badwords system (src/badwords.c is now gone) and StripColors/StripControlCodes
to m_message, multiple netsynch routines to m_server, send_list to m_list, a certain mode
routine to m_svsmode, all /MSG IRC.. webtv stuff to src/modules/webtv.c which is compiled
with m_message.
This means another ~1500 lines of code are now in modules (and thus can be upgraded on
the fly), which brings the total of modulized lines at 32K.
CALLBACKTYPE_CLOAK). This passes 'aClient *sptr, char *host' instead of only 'char *host'
to the cloaking module, which can be useful if you need to cloak on something other than
IP/host. Suggested by fez (#0002275).
Module may still provide only CALLBACKTYPE_CLOAK though, in fact this is what the official
cloaking module does. So no updating of cloaking modules needed.
A side-effect of this "extra cloaking" callback is that we needed to change make_virthost()
which now has an extra parameter in front, and another side-effect is that calling the
CALLBACKTYPE_CLOAK may not work since only *_EX might be available. To my knowledge there
are very few modules (only 1 I know) that will have a problem due to this, so sounds like
an affordable tradeoff.
clients connecting trough a CGI:IRC gateway that is in cgiirc { }. This might also fix a bug
where (g)zlines were not applied to CGI:IRC clients, reported by devil (#0002850).
- Redid some net synching code to make it more efficient (#2716).
- Fixed spamfilter crash problem: the action 'viruschan' is now no longer incompatible
with target 'user'. Reported by Monk (#0002570).
This should get rid of some annoying untracable (and usually rare) crashbugs in the
old resolver. Besides that, it makes things look more clean and understandable.
This should be the fix for the following bugids (all the same issue): #2499, #2551, #2558,
#2559, #2603, #2642, #2502, #2501, #2618, #2616.
Feedback and testing is very much welcomed (syzop@unrealircd.com).
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).
and 2000 lines total that can be hotfixed if needed ;). The effort involved in moving all
this sucks a lot though :/. This might need some more testing to make sure it doesn't break
anything.
- Updated support OS list in documentation.
- Redid include dependencies in Makefile, this makes things safer because on any .h change it
would force a recompile of all files, but it could mean things will be a bit slower for us
coders unless we tweak it later on.
- Changed whois a bit to print less useless results.
- Added several indicators to the "detect binary incompatible modules"-system such as detecting
of a ziplinks module on non-ziplinks (on windows this is ok however), nospoof module on a
a server without nospoof server, etc. Hopefully this will help some people preventing odd
crashes because they did not recompile or (re)install modules properly.
- Added './unreal backtrace', so far this has only been tested on Linux and FreeBSD.
- Fixed a bug making ./Config not load the previously stored settings on Solaris 10 and
probably other Unixes, reported by lion-o (#0002474).
- Modulized a lot of commands and related subfunctions: NICK (750 lines), USER (200),
MODE (2300), WATCH (250), JOIN (600), PART (250), MOTD (100), OPERMOTD (100),
BOTMOTD (100), LUSERS (100). More will follow soon (probably including more subfunctions
related to existing commands).
/connect or autoconnect) and was not present in the cache. Reported and traced by sh0
(#0001976).
- Fixed compile bug at *NIX caused by ModuleGetErrorStr fix.
- 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).
- Added release notes (no, we won't release 3.2.1 anytime soon.. just updating ;p).
- Added various extra messages to make it a bit more easier for people who are
upgrading (win32 commands.dll, cloaking mod).
- Made win32 ssl<->non-ssl modules binary compatible.
- Added ssl/non-ssl check in Mod_Version on *NIX.
- Added set::options::flat-map: This makes all servers look like they are linked
directly to the server you are on (/map, /links), thus you cannot see which server
is linked to which ("hopcount"). This can make it a bit harder for kiddies to find
any 'weak spots' (which server to attack/[D]DoS). Obviously opers will always
see the real map.
