these "network settings" and other settings has been lost in time.
Rename some of these variables and macro's.
ircnetwork -> NETWORK_NAME
ircnet005 -> NETWORK_NAME_005
defserv ->? DEFAULT_SERVER
hidden_host -> CLOAK_PREFIX
helpchan -> HELP_CHANNEL
Also one config change (visible to admins):
set::hiddenhost-prefix is now set::cloak-prefix
We still accept the old name, though.
The example conf has been updated as well, but not the wiki yet.
of targets accepted for a command, eg /MSG nick1,nick2,nick3,nick4 hi.
Also changed the following defaults (previously hardcoded):
* PRIVMSG from 20 to 4 targets, to counter /amsg spam
* NOTICE from 20 to 1 target, to counter /anotice spam
* KICK from 1 to 4 targets, to make it easier for channel operators
to quickly kick a large amount of spambots
See https://www.unrealircd.org/docs/Set_block#set::max-targets-per-command
(actually still need to write the documentation)
not picked up by any other IRCd. The 005 tokens KNOCK MAP USERIP are
now used instead. We do not announce STARTTLS in 005 anymore as this
is way too late (post-handshake, sensitive info already sent and/or
received). Not to mention STARTTLS is not the preferred method to
setup a secure connection in the first place.
Module coders: this means CommandAdd() with M_ANNOUNCE should no
longer be used. If a 3rd party module does use it, then UnrealIRCd
will now raise a warning. In a later UnrealIRCd version the flag
is likely to be removed completely so would cause a compile error.
(I doubt any module uses this anyway... but still..)
* You can now set more custom limits. The default settings are shown below:
set {
topic-length 360; /* maximum: 360 */
away-length 307; /* maximum: 360 */
quit-length 307; /* maximum: 395 */
kick-length 307; /* maximum: 360 */
};
* A new 005 token has been added: QUITLEN. Works similar to KICKLEN.
The ability to adjust the topic length in the configuration file was
requested by Amiga600 in https://bugs.unrealircd.org/view.php?id=4692
At that place is also additional information on why there is a
"maximum" for topic length.
There's now no longer a difference between a rehash or boot.
2) Other cleanups in s_conf.c as well. Looks better now.
3) Sort the 005 tokens alphabetically. Enforcing some other 'logical order'
was futile and this makes things consistent between rehashes.
For module coders this adds some new functions, such as IsupportSet,
IsupportSetFmt and IsupportDelByName. I'll document them later.
In 3.2.x we didn't fix these bugs since servers are trusted and
should send correct commands. In 4.0.x we changed this so we would
fix them when we come across such issues at normal priority (not
consider them security issues). I now took it a step further and
actively checked/looked for these issues and a bunch of them were
found. Almost all are NULL pointer dereferences, with some exceptions.
* S2S: MODE: check conv_param return value (NULL ptr crash)
* S2S: MODE: floodprot: More checks (NULL ptr crash)
* S2S: MODE: OOB write of NULL (write NULL past last element in an array)
* S2S: NICK: old compat fixes (NULL ptr crash)
* S2S: PROTOCTL: Check for double SID=
* S2S: SERVER: require at least 3 parameters (NULL ptr crash)
* S2S: SJOIN: require at least 3 parameters (NULL ptr crash)
* S2S: SJOIN: Fix OOB read (read 1 byte past buffer)
* S2S: TKL: validate set_at and expire_at (NULL ptr crash)
* S2S: TKL: require at least 9 parameters for spamf, not 8 (NULL ptr crash)
* S2S: TKL: ignore invalid spamfilter matching type (remove abort() call)
* S2S: TOPIC: querying for topic is not permitted (NULL ptr crash)
* S2S: UID: require 12 parameters (NULL ptr crash)
* S2S: WATCH: this is not a server command (NULL ptr crash)
* Fix OOB read (1 byte beyond string) for timevals. This was reachable
from config code, TKL (S2S) and /*LINE (Oper). In practice no crash.
* MODE: make code less confusing (effectively no change)
* TRACE: remove strange output in case of 0 lines of output
* Fix unimportant memory leak on boot (#4713, reported by dg)
* Fix small memory leak upon 'DNS i' (oper only command)
* Always work on a copy in clean_ban_mask(). This fixes a bug that could
result in a strlcpy(buf, buf, sizeof(buf)). So, overlapping strings,
which is undefined behavior.
it to 'no', the default is 'yes' (on). Requested by Robin (#0003885) as
UHNAMES may increase the time of the nick list being loaded from 1 to 4
seconds when joining several channels with more than 1000 users. As this
problem is only present on some networks, we keep UHNAMES enabled by
default.
- Modulized NAMES command (can now be upgraded on the fly, if ever needed).
- Added NAMESX support, seeing both mIRC (5.17) and XChat support this. What this does is
send all rights of all users on the channel in the NAMES reply (eg: @+Syzop if the user is +ov)
instead of only the highest one (@Syzop in previous example). We only do so if the client
explicitly requested this via a NAMESX in a PROTOCTL message (eg: 'PROTOCTL NAMESX').
Note that there is a glitch: since most clients only send the PROTOCTL NAMESX after they
see NAMESX listed in the 005 announce message this has the effect that if there are
set::auto-join channels present (where users are automatically joined to by the server) the
extended NAMES reply will not be sent for those channels, because from the IRC server' point
of view the join happened before the PROTOCTL and hence it does not know the client wanted
NAMESX at that point (the result is not catastrophic: the old-style NAMES is sent for those
channels). Anyway, for all non-autojoin channels this works great. So still worth adding IMO.
Originally suggested in #0000606.
Side note: this does not mean we dropped the idea of (also) having a challenge-response
system for good ;).
