Brian Masney and S.Kalyanasundraram and maintained for application to
the DHCP-4 sources by David Cantrell has been included. Please be
advised that these sources were contributed, and do not yet meet the
high standards we place on production sources we include by default.
As a result, the LDAP features are only included by using a compile-time
option which defaults off, and if you enable it you do so under your
own recognizance. We will be improving this software over time.

DDNS code to use the bind libraries. This patch fixes that breakage and
includes support for the new DDNS code. This patch also deletes some dead
code and neatens up some log messages.
which permits a DHCP server operating in communications-interrupted state
to 'rewind' a lease to the state most recently transmitted to its peer,
greatly increasing a server's endurance in communications-interrupted.
This is supported using a new 'rewind state' record on the dhcpd.leases
entry for each lease. [ISC-Bugs #19601]
function of the same name and presents the results as a data expression.
This function can be used to incorporate the system level hostname of
the system the DHCP software is operating on in responses or queries (such
as including a failover partner's hostname in a dhcp message or binding
scope, or having a DHCP client send any system hostname in the host-name or
FQDN options by default). [ISC-Bugs #17351]
environments where DHCP servers can be reasonably guaranteed to be
"down" when the failover TCP socket is severed, "auto-partner-down".
This parameter is not generally safe, and by default is disabled, so
please carefully review the documentation of this parameter in the
dhcpd.conf(5) manpage before determining to use it yourself.

been repaired. Other USE_ overrides should work better. [ISC-Bugs #19434]
- A check for the local flavor of IFNAMSIZ had a broken 'else' condition,
that probably still resulted in the correct behaviour (but wouldn't use
a larger defined value provided by the host OS). [ISC-Bugs #19434]
a DHCID (still currently implemented as a TXT RR). This would cause later
expiration or release events to fail to remove the domain name. The feature
now also inserts the client's up to date DHCID record, so records may safely
be removed at expiration or release time. Thanks to a patch submitted by
Christof Chen. [ISC-Bugs #19500]
to stop receiving packets is fixed. The same fix also means that the MAC
address will no longer appear 'bogus' on DLPI-based systems.
[ISC-Bugs #19186]
- A bug in select handling was discovered where the results of one select()
call were discarded, causing the server to process the next select() call
and use more system calls than required. This has been repaired - the
sockets will be handled after the first return from select(), resulting in
fewer system calls. [ISC-Bugs #19186]
the client has been deprived of all A and AAAA records (not only the last
one of either of those). This resolves a bug where dual stack clients
would not be able to regain their names after either expiration event.
[ISC-Bugs #18716]
which is seen in some malformed DHCP client packets, was modified.
It now logs the universe name, and does not log the length values
(which are bogus corruption read from the packet anyway). It also
carries a hopefully more useful explanation. [ISC-Bugs #18241]
no matter how many interfaces are involved, differentiating the
interfaces the packets were received on by the interface index supplied
by the OS.
- The relay agent no longer listens to the All DHCP Servers Multicast
address.
- A bug was fixed in data_string_sprintfa() where va_start was only called
once for two invocations of vsprintf() variants.
