When a user is rejected, remember the hash value of the
ban mask (for klines/glines, hash value of the user part
XOR hash value of the host part) with the rejected IP;
if the kline/gline/xline is removed, remove rejects with
the same hash value also. Note that this does not happen
for expiries; this is deliberate.
Rejects for no auth{} or dnsbl put a hash value of 0;
they cannot be removed selectively.
- Change find_exact_conf_by_address() to work for dlines also.
- Use find_exact_conf_by_address() to find the dline and
abort immediately if there is no such dline.
- When removing a permanent dline, remove the dline from
the data structures instead of rehashing bans.
- Convert alternative ways to write the same dline to the
one in the found dline. (This was changed in unkline too.)
- Use find_exact_conf_by_address() to find the kline and
abort immediately if there is no such kline.
- When removing a permanent kline, remove the kline from
the data structures instead of rehashing bans.
This changes flattened /links output to disclose less
routing information and slightly increases memory "leak"
from server names that do not come back anymore.
WHOIS: Show the given nick in ERR_NOSUCHNICK even if it
starts with a digit. This is safe because the last
parameter is a nick and never a UID. (The first parameter
in a server-server two-param whois is a UID/SID.)
If we are connecting outward to a server, check if the
server name they sent is the same as what we tried to
connect to. Previously such a connection could succeed
if there existed connect blocks with the same IP and
passwords for the other server name.
Another handling of SJOINs without nicks:
Propagate them if the channel is +P or the channel
already existed, otherwise remove the channel again
and do not propagate the SJOIN.
addition to +i. As before, a restrictive mode must be in
place at /invite time for the invite to have an effect;
+r does not count as a restrictive mode if the user is
logged in; +l and +j always count as restrictive modes to
allow for cases where they would allow join at /invite
time but not when the user tries to join.
