                Internet Systems Consortium DHCP Distribution
                            Version 4.4.2
                            22 January 2020
                             Release Notes

                              NEW FEATURES

Please note that that ISC DHCP is now licensed under the Mozilla Public License,
MPL 2.0. Please see https://www.mozilla.org/en-US/MPL/2.0/ to read the MPL 2.0
license terms.

While release 4.4.2 is primarily a maintenance release that addresses a number
of defects, it does introduce a few new features:

- Keama - Keama is a migration utility that assists in converting ISC DHCP
  server configuration files to Kea configuration files.  It is found in the
  keama subdirectory and includes a README.md file with instructions on how
  to build it as well as a manpage on its usage.

- Two new server parameters related to ping checking were added:

1. ping-cltt-secs which allows the user to specify the number of seconds
   that must elapse since CLTT before a ping check is conducted.

2. ping-timeout-ms which allows the user to specify the amount of time the
   server waits for a ping-check response in milliseconds rather than in
   seconds.

In general, the areas of focus for ISC DHCP 4.4 were:

1. Dynamic DNS additions
2. dhclient improvements
3. Support for dynamic shared libraries

Dynamic DNS Improvements:

- We added three new server configuration parameters which influence DDNS
  conflict resolution:

    1. ddns-dual-stack-mixed-mode - alters DNS conflict resolution behavior
    to mitigate issues with non-compliant clients in dual stack environments.

    2. ddns-guard-id-must-match - relaxes the DHCID RR client id matching
    requirement of DNS conflict resolution.

    3. ddns-other-guard-is-dynamic - alters dual-stack-mixed-mode behavior to
    allow unguarded DNS entries to be overwritten in certain cases

- The server now honors update-static-leases parameter for static DHCPv6
  hosts.

dhclient Improvements:

  - We've added three command line parameters to dhclient:

    1. --prefix-len-hint - directs dhclient to use the given length as
    the prefix length hint when requesting prefixes

    2. --decline-wait-time - instructs the client to wait the given number
    of seconds after declining an IPv4 address before issuing a discover

    3. --address-prefix-len - specifies the prefix length passed by dhclient
    into the client script (via the environment variable ip6_prefixlen) with
    each IPv6 address.  We added this parameter because we have changed the
    default value from 64 to 128 in order to be compliant with RFC3315bis
    draft (-09, page 64) and RFC5942, Section 4, point 1.
    **WARNING**: The new default value of 128 may not be backwardly compatible
    with your environment. If you are operating without a router, such as
    between VMs on a host, you may find they cannot see each other with prefix
    length of 128. In such cases, you'll need to either provide routing or use
    the command line parameter to set the value to 64. Alternatively you may
    change the default at compile time by setting DHCLIENT_DEFAULT_PREFIX_LEN
    in includes/site.h.

  - dhclient will now generate a DHCPv6 DECLINE message when the client script
    indicates a DAD failure

Dynamic shared library support:

  Configure script, configure.ac+lt, which supports libtool is now provided
  with the source tar ball.  This script can be used to configure ISC DHCP
  to build with libtool and thus use dynamic shared libraries.

Other Highlights:

 - The server now supports dhcp-cache-threshold for DHCPv6 operations
 - The server now supports DHPv6 address allocation based on EUI-64 DUIDs
 - Experimental support for alternate relay port in the both the server
   and relay for IPv4, IPv6 and 4o6 (see: draft-ietf-dhc-relay-port-10.txt)

*: Recursive revision bump for openssl 1.1.1.

isc-dhcp4: add LDAP as an option; pkglint fixes

Update isc-dhcp4 and related packages to 4.3.1.

                        Changes since 4.3.1rc1

- None

                        Changes since 4.3.1b1

- Modify the linux and openwrt dhclient scripts to process information
  from a stateless request.  Thanks to Jiri Popelka at Red Hat for the
  bug report and patch.
  [ISC-Bugs 36102]

- Remove more unused RCSID tags.  These weren't noticed in 4.3 as
  the code isn't used anymore but we remove them here to keep the
  code consistent across versions.
  [ISC-Bugs #36451]

Recursive PKGREVISION bump for OpenSSL API version bump.

Update ISC DHCP related pacakges to 4.2.0.

			Changes since 4.2.0 (new features)

- If a client renews before 'dhcp-cache-threshold' percent of its lease
  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]
  Updated this patch to support asynchronous DDNS.  If the server is
  attempting to do DDNS on a lease it should be udpated and written to
  disk even if that wouldn't be necessary due to the thresholding.
  [ISC-Bugs #26311]

- The 'no available billing' log line now also logs the name of the last
  matching billing class tried before failing to provide a billing.
  [ISC-Bugs #21759]

- A problem with missing get_hw_addr function when --enable-use-sockets
  was used is now solved on GNU/Linux, BSD and GNU/Hurd systems. Note
  that use-sockets feature was not tested on those systems. Client and
  server code no longer use MAX_PATH constant that is not defined on
  GNU/Hurd systems. [ISC-Bugs #25979]

- Add a perl script in the contrib directory, dhcp-lease-list.pl, which
  can parse v4 lease files and output the lease information in a more
  human friendly manner.  This was written by Christian Hammers with
  some updates by vom and ISC.  This is contributed code and is not
  supported by ISC; however it may be useful to some users.
  [ISC-Bugs #20680]

- Add support in v6 for on-commit, on-expire and on-release.
  [ISC-Bugs #27912]

- Add support for using classes with v6.
  [ISC-Bugs #26510]

- Update the DDNS code to current standards and allow for sharing
  of DDNS entries between v4 and v6 clients.  The new code is used
  if the ddns-update-style is set to "standard", the older code is
  still available if ddns-update-style is set to "interim".  The
  oldest DDNS code "ad-hoc" has been removed.  Thanks to Thomas Pegeot
  who submitted a patch for this issue.  This patch is based on
  that work with some modifications.
  [ISC-Bugs #21139]

- Add a configuration option to the server to suppress using fsync().
  Enabling this option will mean that fsync() is never called.  This
  may provide better performance but there is also a risk that a lease
  will not be properly written to the disk after it has been issued
  to a client and before the server stops.  Using this option is
  not recommended.
  [ISC-Bugs #34810]

- Add some logging statements to indicate when the server is ready
  to serve.  One statement is emitted after the server has finished
  reading its files and is about to enter the dispatch loop.
  This is "Server starting service.".
  The second is emitted when a server determines that both it and
  its failover peer are in the normal state.
  This is "failover peer <name>: Both servers normal."
  [ISC-Bugs #33208]

- Add support for accessing options from v6 relays.  The v6relay
  statement allows the administrator to choose which relay to
  use when searching for an option, see the dhcp-options man page
  for a description.  The host-identifier option has also been
  updated to support the use of relay options, see the dhcpd.conf
  man page for a description.
  [ISC-Bugs #19598]

- When doing DDNS if there isn't an appropriate zone statement attempt
  to find a reasonable nameserver via a DNS resolver.  This restores
  some functionality that was lost in the transition to asynchronous
  DDNS.  Due to the lack of security and increase in fragility of the
  system when using this feature we strongly recommend the use of
  appropriate zone statements rather than using this functionality.
  [ISC-Bugs #30461]

- Add support for specifying the address from which to send
  DDNS updates on the DHCP server.  There are two new options
  "ddns-local-address4" and "ddns-local-address6" that each take
  one instance of their respective address types.
  [ISC-Bugs #34779]

- Add ignore-client-uids option in the server.  This option causes
  the server to not record a client's uid in its lease.  This
  violates the specification but may also be useful when a client
  can dual boot using different client ids but the same mac address.
  Thank you to Brian De Wolf at Cal Poly Pomona for the patch.
  [ISC-Bugs #32427]
  [ISC-Bugs #35066]

- Extend the DHCPINFORM processing to honor the subnet selection option
  and take host declarations into account.
  Thanks to Christof Chen for testing and submitting the patch.
  [ISC-Bugs #35015]

- Extend the hardware expression to look into the lease structure
  for a hardware address if there is no packet.  This allows the
  server to find the hardware address during on-expiry processing.
  [ISC-Bugs #24584]

- Add definitions for some options that have been specified by the IETF.
  [ISC-Bugs #29268]
  [ISC-Bugs #35198]

			Changes since 4.3.0b1

- Tidy up receive packet processing.
  Thanks to Brad Plank of GTA for reporting the issue and suggesting
  a possible patch.
  [ISC-Bugs #34447]

			Changes since 4.3.0a1

- Modify the message displayed when a process hits a fatal error.
  The new message is much shorter and simply points to the README
  and our website for directions on bug submissions.
  [ISC-Bugs #24789]

- Handle an absent resolv.conf file better.
  [ISC-Bugs #35194]

Add support for Crossbow style NICs on SunOS.
Fix default paths for inet6 files.

DESTDIR support

Update to 4.1.0

ISC DHCP 4.1.x will have several new DHCPv6 features that were not in DHCP 4.0.x. These new features include:

* Support for the rapid-commit option on the client side
* Prefix Delegation support
* IA_TA address support
* A basic DHCPv6 relay agent
* basic DHCPv6 Leasequery support

Despite supporting --sysconfdir isc-dhcp hard sets the location of
configuration files and binaries in a number of cases.  This should hopefully
fix them all.  Without this patch they look in /etc only and fail to start
if the file is not present.

ISC's Dynamic Host Configuration Protocol Distribution provides a
freely redistributable reference implementation of all aspects of
DHCP, through a suite of DHCP tools:

* A DHCP server
* A DHCP client
* A DHCP relay agent

These tools all use a modular API which is designed to be sufficiently
general that it can easily be made to work on POSIX-compliant
operating systems and also non-POSIX systems like Windows NT and
MacOS.

The DHCP server, client and relay agent are provided both as
reference implementations of the protocol and as working, fully-featured
sample implementations. Both the client and the server provide
functionality that, while not strictly required by the protocol,
is very useful in practice. The DHCP server also makes allowances
for non-compliant clients which one might still like to support.

This package contains the Client component.
