* same for scan message
* don't say "you have not registered" on NOTICE in unregistered state.
* made a send_prot(aClient, ConfigItem_link) for sending PROTOCTL message,
takes care of sending ZIP in token in case of a ziplink (indeed, I don't
send "ZIP" if it's not marked as a ziplink).
* added automatic fallback tot uncompressed link in case one of the sides
has zip turned off or not compiled in.
* added configcheck for link::options::zip turned on when not compiled
in (just like we do with ssl).
- Currently it's not possible to compile with ZIP_LINKS _and_ SSL without changing zlib.h :(.
It really sucks... it's because zlib.h has a typedef for 'free_func' and this is also used
in openssl header files as a (useless) name... :((. I did some updates to allow future zlib
changes, dunnow if they will because it can break other zlib programs. It compiled fine at
windows, but not at Linux... you need to replace free_func to zlib_free_func in zlib.h in
order to get ZIP_LINKS + SSL to work... but like I said, that may break programs (ARGH!).
IsHidden(sptr) ? sptr->user->virthost : sptr->user->realhost
stuff to a simple GetHost(sptr) macro (defined in struct.h).
Smaller and less error phrone :). Also fixed the if IsHidden -> if (IsHidden
found by codemastr .
- Made async resolve-and-connect work
- Added link::options::nodnscache which means Unreal will not cache the host forever for
outgoing server connections, you could for example enable this if you are linking two servers
with an often changing host (like dyndns.org).
at windows and not at *NIX? Also it's incompatible with running as a service.
AFAIK it doesn't increase security very much: if you own the box you can easily
snif the keyboard, read the certificate from memory, etc..
- Fixed bug in +q/+a list (/mode #chan q) <= lol this was some historic
bug by DrBin or something ;). In case you wanna know.. the whole loop logic
was wrong... initalisation vs null pointer check... ;).
which is set if dead_link is called. You will now see "Write error",
"Max SendQ exceeded" etc error messages in the quit reason instead of just
the "Dead socket" message. Changed "notice" parameter of dead_link, now just
the reason and not a format string, maybe rename that var.
instead of using a 2nd flag here for the special case of "the first zip msg"
like in hybrid/etc I use cptr->zip->first to flag that. Except for the many
#ifdef ZIP_LINKS blocks added I also had to do some stuff outside it, like
crc32->our_crc32 because zlib defines it, made a READBUF define (8192),
added a msg var to parsing/send functions.. blah.. etc ;P.
I've also put the patch online at www.vulnscan.org/tmp/zip_links.diff so you
can easily look what I've changed.
TODO: ask in ./Config if ziplinks should be enabled and let ./configure check
for zlib + add the library to IRCDLIBS in Makefile if enabled.
TODO: some little code cleanups
then does a -x virthost gets freed and the user can join again/circumvent the ban.
virhost should probably be moved in to the User struct like char virthost[HOSTLEN+1]
but in the meantime I've just removed the free() when someone does -x.
I noticed we already do make_userhost at connect even if mode +x isn't set, and also
is_banned checks if virthost exists.. if so -> check if that's banned... so this
patch won't decrease performance much.
We were doing: T_AAAA, if that fails then T_A. But in that case when a host
has both T_A and T_AAAA entries, the reverse lookup will fail for ipv4.
Now using T_ANY to fetch both T_A and T_AAAA addresses at once.
