has elapsed (default 25%), the server will reuse the allocated lease
(provide a lease within the currently allocated lease-time) rather
than extend or renew the lease. This absolves the server of needing
to perform an fsync() operation on the lease database before reply,
which improves performance. [ISC-Bugs #22228]
[ISC-Bugs #23470] - Modify when an ignore return macro is defined to
handle unsed error return warnings for more versions of gcc.
[ISC-Bugs #23196] - Modify the reply handling in the server code to
send to a specified port rather than to the source port for the incoming
message. Sending to the source port was test code that should have
been removed. The previous functionality may be restored by defining
REPLY_TO_SOURCE_PORT in the includes/site.h file. We suggest you don't
enable this except for testing purposes.
[ISC-Bugs #22695] - Close a file descriptor in an error path.
[ISC-Bugs #19368] - Tidy up variable types in validate_port.
now be correctly written to dhcpd.leases
- If a 'next-server' parameter is configured in a dynamic host record via
OMAPI as a domain name, the syntax written to disk is now correctly parsed
upon restart. [ISC-Bugs #22266]
- set initial delay to 0 to speed up client start
- added 'initial-delay' parameter to possibly revert to old behavior
- better handling of very short (1 or 2s) leases
- client lease records are recorded at most once every 15 seconds
- ICMP ping-check is now timed more precisely
- Servers that don't offer lease-time are now black-listed
[ISC-Bugs #19660]
21518 we changed the print routines to always display time values
as a hex list. This had a side effect of printing all data strings
as a hex list. We shall investigate other ways of displaying time
values more usefully. [ISC-Bugs #22626]
[ISC-Bugs #20418] - Some systems don't support the "%s" argument to
strftime, paste together the same string using mktime instead.
[ISC-Bugs #19596] - When parsing iaid values accept printable
characters.
[ISC-Bugs #21585] - Always print time values in omshell as hex
instead of ascii if the values happen to be printable characters.
Correct error handling in DLPI [ISC-Bugs #20378]
Remove __sun__ and __hpux__ typedefs in osdep.h as they are now being
checked in configure. [ISC-Bugs #20443]
Modify how the cmsg header is allocated the v6 send and received routines
to compile on more compilers. [ISC-Bugs #20524]
When parsing a domain name free the memory for the name after we are
done with it. [ISC-Bugs #20824]

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]
merge, arrange to handle callbacks from the socket code after we've deleted
the socket and deal with the quantum issue in the tasks. This last will
be removed shortly as a better fix is now available.
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.

- 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]
