Add support to set high and low thresholds for pools for
v4 and v6. A message will be emitted when the usage of
the pool first exceeds the high threshold. More messages
will be skipped until the usage has gone below the low
threshold and then back above the high threshold.
Tidy up several small tickets
Correct parsing of DUID from config file, previously the LL type
was put in the wrong place in the DUID string.
[ISC-Bugs #20962]
Add code to parse "do-forward-updates" as well as "do-forward-update"
[ISC-Bugs #31328]
Remove log_priority as it isn't currently used.
[ISC-Bugs #33397]
Increase the size of the buffer used for reading interface information.

Add code to suppor on {commit expiry release} statements for DHCPv6.
There are several pieces to this change
1) Add space in the iasubopt structure to hold the statement pointers
2) Update the execute code to fill in the structures as necessary
3) Execute the statements when appropriate
Many of the changes in the non-v6 code are to pass the v6 structures
around to the execute code.
When processing an IA that we've seen check to see if the
addresses are usable (not in use by somebody else) before
handing it out.
When reading in leases from the file discard expired addresses.
When picking an address for a client include the IA ID in
addition to the client ID to generally pick different addresses
for different IAs.

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.

the end of the max-life and preferred-life clauses. In order to be
backwards compatible with older lease files not finding a semi-colon
is also accepted. [ISC-Bugs #22303].
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.

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]
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.

not be applied to clients addressed within that network was repaired.
- When configuring a "subnet {}" or "subnet6 {}" without an explicit
shared-network enclosing it, the DHCP software would synthesize a
shared-network to contain the subnet. However, all configuration
parameters within the subnet more intuitively belong "to any client
on that interface", or rather the synthesized shared-network. So,
when a shared-network is synthesized, it is used to contain the
configuration present inside the subnet {} clause. This means that
the configuration will be valid for all clients on that network, not
just those addressed out of the stated subnet. If you intended the
opposite, the workaround is to explicitly configure an empty
shared-network.
- A bug was fixed where Information-Request processing was not sourcing
configured option values.
- A warning was added since the DHCPv6 processing software does not yet
support class statements.

control lists. These directives may be used to assist in re-addressing
address pools without having to constantly reconfigure the server. Please
see 'man dhcpd.conf' for more information on allow/deny 'after time' syntax.
Thanks to a patch from Christof Chen. [ISC-Bugs #17110]
follow the leases through their lifecycles. This enables DDNS teardowns
on leases that are assigned and expired inbetween a server restart (the
state is recovered from dhcpd.leases). Arbitrary user-specified binding
scopes ('set var = "value";') are not yet supported.
