processing if the configuration included overlapping pools or
multiple fixed-address entries for a single address. This issue
affected both IPv4 and IPv6. The fix allows a server to detect such
conditions, provides the user with extra information and recommended
steps to fix the problem. If the user enables the appropriate option
in site.h then server will be terminated
buffer space for bootp and use a better constant - DHCP packet
size instead of DHCP packet size + udp and iP headers.
Check that we have a packet->options structure before using it.
Only process packets that are longer than a bootp fixed packet
including server and file names. Previously we allowed for
shorter packets but that wasn't working and nobody noticed.
configured during compilation time. Even though RFC2132 does not allow
to store more than one domain in domain-name option, such behavior is
now enabled by default, but this may change some time in the future.

than the dispatch handler. This fixes an issue where omshell, when
run from the same platform as the server, would appear to fail to
connect. This is a companion to #21839. [ISC-Bugs #23592]
[ISC-Bugs #23045] Typos in client/scripts/openbsd
[ISC-Bugs #23565] In the client scripts add a zone id (interface id) if
the domain search address is link local.
[ISC-Bugs #1277] In some of the client scripts add code to handle the
case of the default router information being changed without the address
being changed.
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.

any IPv4 address assigned. Also extended logging message about discarding
packets with invalid hlen with information about relevant interface name.

[ISC-Bugs #17959] add text to AIX section describing how to have it send
responses to the all-ones address.
[ISC-Bugs #19615] update the includes in dhcpctl/dhcpctl.3 to be more correct
[ISC-Bugs #20676] update dhcpd.conf.5 to include the RFC numbers for DDNS

- 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

to disable writing a pid file. Add the option "-pf pidfile"
