(HOOKTYPE_PACKET). Replacing the 'text to be sent' to a client is
supported, which allows character(set) conversion in a module.
Note that modifying an incoming message by the hook is not supported.
- When checking if a user is banned, we always check the cloakhost too. Previously we could
not do this if the user had a /VHOST (=a minority of the cases, but still...). In short,
this is some extra protection to combat ban evasion.
- Performance of is_banned() *slightly* improved (just 1-2 usec, but 7 usec if no bans).
- [Module coders] For extban routines, we now offer a routine extban_is_banned_helper(buf)
which can be used instead of the ban_realhost/etc static chars stuff, see
extban_modeq_is_banned for a (real-life) example of how this is used.
- [Services coders!] Added PROTOCTL CLK (requires NICKv2) which adds an extra field in the
NICK command (when a user connects) right before the infofield (gecos).
The added field contains the cloaked host, that is: the masked host if +x would have been
set. This field is ALWAYS sent, regardless of whether the user is actually +x or not.
Services can then store this field in memory, to know the host of the user if the user
is set +x (+x-t). This is a (better) alternative to PROTOCTL VHP, with no race conditions,
and avoids some other VHP problems.
VHP will stay supported though... so it's not mandatory to switch over.
- 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).
to send to normal users w/the snomask set.
- Fixed dcc filtering a bit more.
- Made usermode 'g' operonly since it didn't do much, reported by DukePyrolator (#0002024).
- Fixed a few wrong macro's (ircstrdup/ircfree) in s_conf.c causing
very weird behavior... This also fixes a bug where set::spamfilter::ban-reason
would have the value of ban-time.
- Improved spamfilter again.
- The new syntax is:
/spamfilter [what] [type] [action] [tkltime] [reason] [regex]
[tkltime] specifies the duration of any *lines placed by this rule.
[reason] specifies the *line, kill and/or block reason.. no spaces
allowed, but '_' will be escaped to a space.
In both cases you can simply use '-' to skip and use the default.
Ex: /spamfilter add p block - - Come watch me on my webcam
/spamfilter add p gline 3h Please_go_to_www.viruscan.xx/
nicepage/virus=blah Come watch me on my webcam
- A message is now shown if the msg/notice/dcc is blocked.
- There are 2 new spamfilter action types:
'dccblock' will mark the user so (s)he's unable to send any files by DCC.
'viruschan' will part the user from all channels and join
set::spamfilter::virus-help-channel (default: #help).
this action might be improved to do more later.
- Internal: added EXTTKL PROTOCTL, this determinates if 10 parameters
instead of 8 are supported for m_tkl (used by spamfilter add).
This new system needs some testing... :)
- Fixed 'no server notice on /restart or /die', reported by Lx (#0001062). This was caused
by a bug in flush_connections(&me), hopefully there won't be any side effects.
- Fixed file owner problems when IRC_UID/IRC_GID is used (eg: when running chrooted).
- Fixed crashbug if we were unable to write a remote include file to disk.
"blind proxies" (like HTTP POST proxies).
- WebTV updates: made it so (user generated) channel notices are now displayed as
privmsgs in the channel. Also made the /knock channelnotice a privmsg for webtv.
this will currently produce a lot of warnings with -Wall.
- Fixed 159 of 184 warnings detected by the above, the other warnings are false.
Most warnings had to do with long vs int, and thus the format strings (%d->%ld)
or the vars (int->long) have been changed (many of these were time_t/TS vs int).
Only a few rare crashbugs were discovered.
- Module coders: for HOOKTYPE_LOCAL_CHANMODE the 'sendts' parameter was changed
from type 'int' to 'time_t', while in most circumstances (like on ia32)
you won't notice, I suggest you to update your callback functions anyway.
- Possibly fixed an issue with set::modes-on-join and mode +f, it could have
set random remove-chanmode times in the default chanmode line.
- (Just for the record, this audit has nothing to do with the ircnet buffer overflow,
unrealircd is not vulnerable)
- Various fixes
- Visual bug regarding +f & server synching, it was sometimes setting mode +f multiple
times depending on the ban-/userlist.
- Fixed a possible desynch regarding chmode +L.
- Fixed possible client confusion regarding bans.
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 .
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
