- Added support for "stacked" extbans. Put simply this allows extban combinations
such as ~q:~c:#test to only silence users on #test, for example. This feature
is enabled by default, but can be disabled during ./Config -advanced.
This feature was suggested by Shining Phoenix (#0003193), was then coded
by aquanight for U3.3, and later on backported and partially redone by Syzop.
Module coders:
In an extban ~x:~y:something where we call ~x the 1st, and ~y the 2nd extban:
Since stacked extbans only makes sense where the 1st one is an action
extended ban like ~q/~n/~j, most modules won't have to be changed, as
their extban never gets extended (just like ~c:~q: makes no sense).
However, you may still want to indicate in some cases that the extban your
module introduces also shouldn't be used as 2nd extban.
For example with a textban extban ~T it makes no sense to have ~n:~T.
The module can indicate this by setting EXTBOPT_NOSTACKCHILD in
the ExtbanInfo struct used by ExtbanAdd().
For completeness I note that action modifier extbans are indicated by
EXTBOPT_ACTMODIFIER. However, note that we currently assume all such
extbans use the extban_is_ok_nuh_extban and extban_conv_param_nuh_or_extban
functions. If you don't use these and use EXTBOPT_ACTMODIFIER, then things
will go wrong with regards to stack-counting.
Module coders should also note that stacked extbans are not available if
DISABLE_STACKED_EXTBANS is defined.
- Added extended ban ~R:<nick>, which only matches if <nick> is a registered
user (has identified to services). This is really only useful in ban
exemptions, like: +e ~R:Nick would allow Nick to go through all bans if he
has identified to NickServ. This is often safer than using +e n!u@h.
- Added Extended Invex. This is very much like extended bans, in fact it
supports some of the same flags. Syntax: +I ~character:mask
Currently supported are: ~c (channel), ~r (realname) and ~R (registered).
This can be useful when setting a channel invite only (+i) and then
setting invite exceptions such as +I ~c:#chan (or even ~c:+#chan), while
still being able to ban users.
Because action modifiers (~q/~n/~j) make no sense here, extended invex
stacking (+I ~a:~b:c) makes no sense either, and is not supported.
Suggested by DanPMK (#0002817), parts based on patch from ohnobinki.
Module coders: set EXTBOPT_INVEX in the ExtbanInfo struct used by
ExtbanAdd() to indicate that your extban may also be used in +I.
- Invex (+I) now always checks cloaked hosts as well. Just like with bans,
it checks them also when the user is not currently cloaked (eg: did -x, or
is currently using some VHOST).
- Fixed client desynch caused by (un)banning, reported by Sephiroth (#2837).
- Separate m4 macros into *.m4 files (it is much easier to run aclocal now).
- Remove unused DOMAINNAME macro and --with-hostname= options as the DOMAINNAME macro isn't used anywheres and its use shouldn't be encouraged.
- autogen.sh to bootstrap the buildsystem. We now maintain setup.h with autoheader.
- --disable-blah now does the opposite of --enable-blah. The same for --with-blah and --without-blah. (This makes Gentoo users happier).
- Remote MOTD support. Not adequately tested. Required restructuring of the asynchronous download callback and handler.
- Added some consts throughout url.c, etc.
- Fix segfault where the an include directive specifies a URL and cURL follows redirects, resulting in a different resultant URL. The remote includes code would look for the an include block using the resultant URL and assume that it would be found. The new code searches differently, has new checks, and ignores the resultant URL.
- Removed duplicated m_motd() and friends that were both in modules and s_serv.c. The copies in s_serv.c (core) were overriding the in-module functions.
- 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).
