This requires both servers to be using UnrealIRCd 6 and there
should be no UnrealIRCd 5 server in-between (eg an old hub).
This also changes tls_cipher() to expect a Client * argument.
And tls_get_cipher() can now safely be called on any client,
including remote clients, and it will return the cipherstring
if it is known via moddata.
We used to always send the long version:
SJOIN ts #channel +sntkl key 999 :xxx
From now on we only send that for the first SJOIN for a channel
when syncing. For any subsequent SJOINs (so for larger channels or
with lots of bans/exempts/invexes) we will use the short version:
SJOIN ts #channel :xxx
We now do it that way because the remote side already received
all the modes the first time, so they are redundant in the
subsequent SJOINs for the same channel.
Especially if you have a channel with a large mode string, such as
+lLfH 99 #redirectchan [30j#i10,40m#m10,7c#C15,10n#N15,30k#K10]:15 100:1d
it was previously 1) wasting bandwidth and 2) unnecessary CPU
trying to merge channel modes that were already the same.
which BANCHK_* events you want to listen, eg BANCHK_JOIN, BANCHK_MSG.
You can use BANCHK_ALL to watch on all events.
Only BANCHK_TKL is not included there and needs an explicit
BANCHK_ALL|BANCHK_TKL.
The caller will now take care of BANCHK_* filtering so we won't
waste any CPU on calling an is_banned() function that isn't
interested at all in the event that we have.
Also, no longer require an extban->is_banned function, since some
extbans don't use it. This too saves useless calls.
Currently only supported option is:
BCTX_CONV_OPTION_WRITE_LETTER_BANS: always write letter bans
This removes the NULL pointer magic that i was not happy about.
If you don't indicate NEXTBANS support then we will send old fashioned
extended bans to you.
Note that eventually we will likely require named extended bans support,
but that will be UnrealIRCd 7 / 8.... ;)
server to server traffic to be letter extbans.
Yeah this is a tad ugly, but the alternative was worse, see
header of the file for the full story.
Module is loaded by default (obviously).
Still to do: only do this for non-U6 servers (add some PROTOCTL)
And probably alter clean_ban_mask because I don't like the
magic on NULL client at the moment.
In U5 channel->creationtime could be 0 momentarily, eg for a new
channel, but nowadays we set channel->creationtime to TStime()
if the channel gets created in make_channel() [*]
[*] which was previously called get_channel() by the way
Also update some comments in mode.c to make things more clear.
The only stuff we still have is if a bounce servermode is detected
(incoming) then we just ignore it.
All this bounce stuff wasn't used much, and didn't even work
(was always sending empty bounce string). It was only complicating
the code everywhere with stupid stuff like:
*x++ = bounce ? '+' : '-';
what = MODE_DEL;
caused a bounce, or was supposed to (never really worked either).
We now ignore the mode (which was de-facto what we did anyway)
and also log it in that way.
configuration file via set::named-extended-bans <yes|no>; and now
defaults to yes.
Still to do:
* explicitly set names instead of using stupid module names
* update test suite to check for these new names (other git tree)
* backwards compatible sending to U5 and lower using ugly shit
The .conv_param() now receives the ban minus the ~own-extban.
And it should also return the part minus the ~own-extban.
Changes to findmod_by_bantype():
1) Takes a string now, rather than a single char value,
so it is ready for named extbans.
2) Second parameter added so you can easily jump to the remainder.
Eg:
extban = findmod_by_bantype(b->banstr, &nextbanstr);
[..check if extban is non-NULL and then..]
b->banstr = nextbanstr;
When extban->is_ok() is called the banstr now no longer points
to "~x:something" but to "something".
Just like we did for extban->is_banned().
Again, need this for later too...
have that in dns.c. Also remove verify_hostname() from dns.c and
integrate it in valid_host() which now takes a second argument
named 'strict'. Call valid_host() with strict set to 1 if the
hostname should be checked to be a valid DNS hostname, eg the
host may not contain stuff like ':' or '/'. Use 0 otherwise
for the loose check, eg if you are not sure if the passed host
is an IP address or a host, or if it is for a vhost.
