This backports the code responsible for SPKI digests from release/4.
It also adjusts doc/reference.conf to note that SPKI digests are now
supported, and how to generate them. It does NOT backport the mkfingerprint
program -- the instructions in reference.conf are sufficient. I am ofcourse
open to anyone else backporting the program, but I don't see the need.
While functionally compatible with the implementation in ElementalIRCd, our approach is different,
specifically pre-calculating the bitmask at config load time. This is more efficient, and allows us
to report errors as part of the configuration phase.
This allows multiple improvements to m_sasl. With this change, the SASL
authentication gets aborted immediately when services are offline.
Additionally, we send the SASL ENCAP messages directly to the specified
SASL agent.
There are IPv4 and IPv6 ranges reserved for documentation and example code;
use these to minimize the risk if someone accidentally uses an unmodified
example conf.
Add the flags (auth{} spoof, dynamic spoof) to struct Whowas and add a
show_ip_whowas().
Normal users now see IPs of unspoofed users, and remote opers can see IPs
behind dynamic spoofs. Also, general::hide_spoof_ips is now applied when
the IP is shown, not when the client exits.
This becomes important because of away-notify sending aways to common
channels much like nick changes (which are also paced).
Marking as unaway is not limited (but obviously only does something if the
user was away before). To allow users to fix typos in away messages, two
aways are allowed in sequence if away has not been used recently.
This adds a new ISUPPORT token, NICKLEN_USABLE which is strictly an informative value.
NICKLEN is always the maximum runtime NICKLEN supported by the IRCd, as other servers may
have their own usable NICKLEN settings. As NICKLEN_USABLE is strictly informative, and
NICKLEN is always the maximum possible NICKLEN, any clients which depend on NICKLEN for
memory preallocation will be unaffected by runtime changes to NICKLEN_USABLE.
The default NICKLEN is 50; the default serverinfo::nicklen in the config file is set to
30, which is the NICKLEN presently used on StaticBox.
nenolod gave the thumbs-up to port ircd-seven banfowards to charybdis to spb
for a while, and people have asked about it. Might as well do it since it's a
slow weekend.
Note that as a side effect use_forward is removed from the config and
unconditionally enabled!
