Log Message:
                Internet Systems Consortium DHCP Distribution
                            Version 4.4.1
                           28 February 2018

                             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.

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)

For information on how to install, configure and run this software, as
well as how to find documentation and report bugs, please consult the
README file.

ISC DHCP uses standard GNU configure for installation. Please review the
output of "./configure --help" to see what options are available.

The system has only been tested on Linux, FreeBSD, and Solaris, and may not
work on other platforms. Please report any problems and suggested fixes to
<dhcp-users%isc.org@localhost>.

ISC DHCP is open source software maintained by Internet Systems
Consortium.  This product includes cryptographic software written
by Eric Young (eay%cryptsoft.com@localhost).

                Changes since 4.4.0 (New Features)
- none
                Changes since 4.4.0 (Bug Fixes)

- A delayed-ack value of 0 (the default), now correctly disables the delayed
  feature.  A change in 4.4.0 prohibited lease updates marking leases active
  from be written to the lease file when delayed-ack is 0. This in turn,
  caused servers to lose active lease assignments upon restart.
  [ISC-Bugs #47141]

! Option reference count was not correctly decremented in error path
  when parsing buffer for options. Reported by Felix Wilhelm, Google
  Security Team.
  [ISC-Bugs #47140]
  CVE: CVE-2018-5733

! Corrected an issue where large sized 'X/x' format options were causing
  option handling logic to overwrite memory when expanding them to human
  readable form. Reported by Felix Wilhelm, Google Security Team.
  [ISC-Bugs #47139]
  CVE: CVE-2018-5732

                Changes since 4.4.0b1 (New Features)

- Duplicate address detection when binding to a new IPv6 address was added
  to the following dhclient scripts: linux,freebsd,netbsd,openbsd, and macos.
  The scripts will check for DAD errors after binding to a new IPv6 address
  for at most --dad-wait-time seconds.  If a DAD error is detected the script
  will exit with a value of 3, instructing dhclient to decline the address. If
  dad-wait-time is zero (the default), DAD error checking is not peformed.
  [ISC-Bugs 46805]

- Support for sending and receiving additional DHCP4 options has been added
  to both the dhcpd and dhclient.  Specifically: option codes 93,94, and 97
  (RFC 4578); code 150 (RFC 5859); and codes 209,219, and 211 (RFC 5071).
  Beyond configuring, sending, requesting, and receiving these options neither
  server nor client apply any additional logic based on their values.
  Thanks to Peter Lewis for requesting this change.
  [ISC-Bugs 47062]

                Changes since 4.4.0b1 (Bug Fixes)

- Added clarifying text to dhcpd.conf.5 explaining the class match expressions
  cannot rely on the results of executable statements.
  [ISC-Bugs #45451]

- Fixed a bug which causes dhcpd and dhclient to crash on certain
  systems when given relative path names for lease or pid files on
  the command line.  Affected systems are those on which the C library
  function, realpath() does not support a second parameter value of
  NULL (see manpages for realpath(3)).
  [ISC-Bugs #46957]

- Fixed a build issue when building with embedded BIND9 under OpenBSD that
  was causing BIND9 build to not generate dns/enumclass.h and dns/enumtype.h.
  [ISC-Bugs #46971]

- Added <dhcp>/m4/README to the distribution tarball.  Some versions of
  ac_local() treat the absence of the m4 subdirectory as error rather than
  warning.  This was causing the call to autoreconf, necessary for building
  with libtool, to fail.
  [ISC-Bugs #47075]

                Changes since 4.4.0a1 (New Features)

- Added experimental support for relay port (draft-ietf-dhc-relay-port-10.txt)
  feature for DHCPv4, DHCPv6 and DHCPv4-over-DHCPv6.  Relay port has to be
  enabled at compile time via --enable-relay-port and is fully backward
  compatible (i.e. works with previous implementations of servers and relays
  using the standard ports).  A new --rp <relay-port> command line option
  specifies to dhcrelay an alternate source port for upstream (i.e. toward
  the server) messages.  Thanks to Naiming Shen and Enke Chen of Cisco
  systems for submitting these patches.
  [ISC-Bugs #44535]

- Added --release-on-roam to dhcpd server. When enabled and the server detects
  that a DHCPv6 client (IAID+DUID) has roamed to a new network, it will release
  the pre-existing leases on the old network and emit a log statement similar
  to the following:

      "Client: <id> roamed to new network, releasing lease: <address>"

  The server will carry out all of the same steps that would normally occur
  when a client explicitly releases a lease.  This behavior is disabled by
  default and may only be specified globally. Prior to this the server renders
  the leases unavailable until they expire or the server is restarted. Clients
  that need leases in multiple networks must supply a unique IAID in each IA.
  When release-on-roam is disabled (the default) the server maintains the
  prior behavior of making such leases unavailable until they expire or the
  server is restarted. Clients that need leases in multiple networks must
  supply a unique IAID in each IA.  This parameter may only be specified at
  the global level.  Thanks to Fernando Soto from BlueCat Networks for
  suggesting this change.
  [ISC-Bugs #44576]
  [ISC-Bugs #46849]

- Support for delayed-ack is now compiled in by default. Prior to this
  it had to be enabled at compile time via --enable-delayed-acks. The
  default value for delayed-ack, however, has been changed from 28 to 0
  (i.e. disabled).  This was done to minimize the impact on users not
  currently using the feature.  Please note that the delayed-ack feature
  is not currently compatible with support for DHPCv4-over-DHCPv6 so
  when a 4to6 port command line argument enables this in the server the
  delayed-ack value is reset to 0.
  [ISC-Bugs #42446]

- The server (-6) now honors the parameter, update-static-leases, for static
  (fixed-address6) DHCPv6 leases.  It is worth noting that because stateful
  data is not retained by the server for static leases, each time a client
  requests or renews a static lease, the server will perform DDNS updates for
  it. This may have significant performance implications for environments
  with many clients that request or renew static leases often. Similarly,
  the DNS entries will not be removed by server when a client issues a RELEASE
  nor if the lease is deleted from the configuration. In such cases the DNS
  entries must be removed manually. This feature is disabled by default.
  Thanks to both Bill Shirley and dgutier-at-cern-dot-ch for requesting
  this change.
  [ISC-Bugs #34097]
  [ISC-Bugs #41054]
  [ISC-Bugs #41450]

- Added to the server (-6) a new statement, local-address6, which specifies
  the source address of packets sent by the server. An additional flag,
  bind-local-address6, disabled by default, binds the service socket to
  to local-address6. Note that bind-local-address does not work with direct
  clients: a relay has to forward packets to the server using the
  local-address6 destination.
  [ISC-Bugs #46084]

                Changes since 4.4.0a1 (Bugs)

- The server now recognizes environment variables PATH_DHCPD_DB and
  PATH_DHCPD_PID.  These had been incorrectly compiled out of the code
  unless DHCPv6 support was disabled. Additionally, the server man
  pages were corrected to accurately reflect how the server chooses
  file names (see lease-file-name and pid-file-name statements). Thanks
  to Fernando Soto at Bluecat Networks for bringing this matter to our
  attention.
  [ISC-Bugs #46859]

- Removed an "Impossible condition" error upon exit in the dhcpd server that
  has been shutdown via OMAPI. This condition was only apparent under Solaris
  when building with --enable-use-sockets and --enable-ipv4-pktinfo.
  [ISC-Bugs #36118]

- Corrected some minor Coverity issues: CID 1426059, 1426058, and 1426057.
  [ISC-Bugs #46836]

- Added missing text to dhclient.8 and expanded release note coverage
  for --address-prefix-len changes.

                Changes since 4.3.6 (New Features)

- Added --enable-bind-install to install embedded bind includes and
  libraries. Default is to not install them (it was the previous
  behavior). If you'd like to change the includedir and/or libdir
  installation directories to something different than for ISC DHCP
  you must pass them using the --with-bind-extra-config configuration
  arguments.
  [ISC-Bugs #39318]

- Added support of dynamic shared libraries with libtool. A new
  --enable-libtool configuration parameter is available but
  should not be used directly: *please* read the build configuration
  section in the README file for the recommended procedure.
  [ISC-Bugs #29402]

- IPv6 operation now supports an EUI-64 based address allocation which will
  calculate addresses for clients with EUI-64 DUIDs based on those DUIDs when
  enabled by setting use-eui-64 true.  The parameter may defined down to the
  pool scope.  Note this feature must be compiled in by defining EUI_64 in
  includes/site.h. This flag is undefined by default.
  [ISC-Bugs #43927]

- The directory includes/isc-dhcp and it's only occupant, dst.h, have
  been removed from the source tree.  They are obsolete for branches
  other than v4_1_esv.
  [ISC-bugs #45541]

- Replaced ISC licensing with Mozilla Public License, MPL 2.0 licensing
  throughout.  Please see https://www.mozilla.org/en-US/MPL/2.0/ to read
  the MPL 2.0 license terms.
  [ISC-Bugs #45541]

- Load balancing for failover peers can now be disabled by setting
  "load balance max secs" to 0. Doing so for both peers means both
  servers will respond to all DHCPDISCOVERs or DHCPREQUESTs as soon as
  they are received.
  [ISC-Bugs #39669]

- Added a new dhclient command line parameter, --prefix-len-hint <length>.
  When used in conjunction with -P, it directs dhclient to use the given
  length as the prefix length hint when requesting prefixes.  Thanks to both
  Indy, of the FireballISO open source project and H. Peter Anvin for
  suggesting this change.
  [ISC-Bugs #43792]
  [ISC-Bugs #35112]
  [ISC-Bugs #32228]
  [ISC-Bugs #29470]

- dhclient will now wait for 10 seconds after declining an IPv4 address
  before issuing a discover.  This is in keeping with RFC 2131, section 3.1.5.
  Prior to this dhclient did not wait at all. The amount of time dhclient
  waits can be specified via a new command line parameter:
  --decline-wait-time <seconds>.  A value of zero equates to no wait at all.
  Thanks to Pavel Kankovsky for bringing this matter to our attention.
  **NOTE: THIS IS CHANGE IN DEFAULT BEHAVIOR.
  [ISC-Bugs #45457]

- dhclient will now include the lease address when logging DHCPOFFERs,
  DHCPREQUESTs, DHCPACKs, DHCPRELEASEs, and DHCPDECLINEs.  Additionally,
  DHCPOFFERs will be logged before their corresponding DHCPREQUESTs are
  sent and logged.
  [ISC-Bugs #2729]

- When given the -T command line argument, in addition to reading the
  current lease file, the server will write the leases to a temporary
  lease file.  This can help detect issues in server configuration that
  only surface when leases are written to the file.  The current lease
  file will not be modified and the temporary lease file is removed upon
  completion of the test.
  [ISC-Bugs #22267]

- dhclient will now generate a DHCPv6 DECLINE message containing all IA_NA
  addresses which for which the client script indicates a DAD failure. After
  receiving the DECLINE reply, dhclient will restart the solicit process.
  Note, the client script must exit with a value of 3 to signify that the
  address failed DAD.  Thanks to Jiri Popelka of Red Hat for submitting the
  patch that was the foundation for this change.
  **NOTE: THIS IS CHANGE IN DEFAULT BEHAVIOR.
  [ISC-Bugs #21237]
  [ISC-Bugs #23357]
  [ISC-Bugs #36966]

- Replaced compilation option, enable-secs-byteorder, with a run-time, server
  configuration parameter, check-secs-byte-order.  When enabled, the
  server will check for clients that do the byte ordering on the secs field
  incorrectly.  This field should be in network byte order but some clients
  get it wrong.  When this parameter is enabled the server will examine the
  secs field and if it looks wrong (high byte non zero and low byte zero) swap
  the bytes.  The default is disabled.  This parameter is only useful when
  doing load balancing within failover.
  [ISC-Bugs #45364]

- The default value for server (-6) parameter, prefix-length-mode, has been
  changed from "exact" to "prefer". In "prefer" mode the server will offer
  the first available prefix with the same length as that requested by the
  client. If none are found then it will offer the first available prefix of
  any length.  This is more in line with with RFC 8168 and should improve
  the out-of-the-box user experience.
  **NOTE: THIS IS CHANGE IN DEFAULT BEHAVIOR.
  [ISC-Bugs #45615]

- Added support for 'dhcp-cache-threshold' to IPv6 operation: 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 allows the server to reply without needlessly
  writing leases to disk.  The preferred and valid lease lifetimes
  sent to the client will be reduced by the age of the lease. The option
  may be specified down to the pool level and is supported for all three
  pool types: NA, TA, and PD.
  [ISC-Bugs #45292]

- Added three new server configuration parameters which influence DDNS:
  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
  [ISC-Bugs #42620]
  [ISC-Bugs #42621]
  [ISC-Bugs #44753]

- A "key-algorithm <algorithm>" statement has been added to omshell to
  allow the specification of the key algorithm to use during transaction
  authentication.  Prior to this it was hard-coded to be hmac-md5. It now
  supports all of the same algorithms as the dhcpd server: hmac-md5 (the
  default), hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384, and hmac-sha512.
  [ISC-Bugs #46771]

- Added a server configuration parameter, persist-eui-64-leases, which
  determines whether or not EUI-64 based leases are written to the
  leases file.  Default is true.
  [ISC-Bugs #45046]

- Changed the default value of the prefix length passed by dhclient into the
  client script for each IPv6 address from 64 to 128. This was done to comply
  with RFC3315bis draft (-09, page 64) and RFC5942, Section 4, point 1.
  In addition, dhclient now supports a command line argument,
  --address-prefix-len, which may be used to override the default value.
  **WARNING**: This change 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 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.
  [ISC-Bugs #23252]
  [ISC-Bugs #37221]

- Modified dhclient (-6) to bypass sending a confirm (INIT REBOOT) when it has
  only expired address associations.  Thanks to Jiri Popelka at Red Hat for
  raising the issue and submitting the patch.
  [ISC-Bugs #22675]
                        Changes since 4.3.6 (Bugs):

- Corrected an issue where the server would return a client's previously
  released prefix lease even when the client provides a prefix length
  hint that does not match the prior lease.  Now the server will only
  return the previous lease if it exactly matches the hint.  If not
  it will attempt to allocate a new prefix based on the hint and the
  prefix-length-mode.  Thanks to Tim DeNike - Lightspeed Communications
  for pointing out the error of our ways.
  [ISC-bugs #45780]

- Added explicit include of BIND9 isc/util.h to adapt to revisions
  in BIND9 (see BIND9 ticket #46311).  Prior to this the build was failing
  with implicit function declarations errors for POST() and INSIST().
  [ISC-bugs #46332]

- Added to code ignore empty IPv4 host name option (code 12). While RFC 2132
  states the option cannot be empty, some clients are apparently capable of
  sending it. Prior to this the server was attempting to use it and store it
  in the lease file causing issues with DDNS and so forth.
  [ISC-bugs #43786]

- Corrected dhclient command line parsing for --dad-wait-time that causes
  even valid values to fail as invalid on some environments.
  [ISC-Bugs #46535]

- Replaced iasubopt::heap_index with separate values for active and inactive
  heaps: iasubopt::active_index and iasubopt::inactive_index.  This was done
  to accommodate a change in behavior in BIND9 isc_heap_delete().
  [ISC-bugs #46719]

! Plugged a socket descriptor leak in OMAPI, that can occur when there is
  data pending to be written to an OMAPI connection, when the connection
  is closed by the reader. Thanks to Pavel Zhukov at RedHat for bringing
  this issue to our attention and whose patch helped guide us in the right
  direction.
  [ISC-Bugs #46767]

- The ability of the server to send back dhcp6.vendor-opts values has been
  restored. A change in 4.3.5 (see #29246) which enabled it to send back the
  FQDN option unfortunately broke its ability send back dhcp6.vendor-opts.
  Thanks to Sumant Gupta (sumantgupta at gmail dot com) of Landis+Gry for
  bringing this issue to our attention.
  [ISC-Bugs #46427]

                        Changes since 4.3.6b1

- None

                        Changes since 4.3.5

- The server now allows the client identifier (option 61) to own leases
  in more than one subnet concurrently. Prior to this the server would
  incorrectly release an existing lease in one subnet prior to assigning
  a lease in another subnet. Note that the prior behavior can be still
  be achieved by enabling one-lease-per-client. Thanks to both David Zych at
  the University of Illinois and Norm Proffitt of Infoblox for reporting
  the issue; and Norm for suggesting a solution.
  [ISC-Bugs #41358]

- When replying to a DHCPINFORM, the server will now include options specified
  at the pool scope, provided the ciaddr field of the DHCPINFORM is populated.
  Prior to this the server only evaluated options down to the subnet scope.
  Thanks to Fernando Soto at BlueCat Networks for reporting the issue.
  [ISC-Bugs #43219]
  [ISC-Bugs #45051]

- When memory allocation fails in a repeated way the process writes
  "Run out of memory." on the standard error and exists with status 1.
  [ISC-Bugs #32744]

- The new lmdb (Lightning Memory DataBase) bind9 configure option is
  now disabled by default to avoid the presence of this library to be
  detected which can lead to a link failure.
  [ISC-Bugs #45069]

- The linux interface discovery code has been modified to use getifaddrs()
  as is done for BSD and OS-X.  Prior to this the code would only recognize
  the first address on an interface and thereby omit vlans.
  Thanks to Jiri Popelka at Redhat, Marius Tomaschewski at SUSE, and Wei
  Kong at Novell, who all submitted patches.
  [ISC-Bugs #28761]
  [ISC-Bugs #31992]
  [ISC-Bugs #25428]
  [ISC-Bugs #31940]
  [ISC-Bugs #32935]

- Fixed a bug in OMAPI that causes omshell to crash when a name-value
  pair with a zero length value is shipped in an object. Thanks to
  Fernando Soto at BlueCat Networks for reporting the issue and
  supplying the patch.
  [ISC-Bugs #29108]

- On 64-bit platforms, dhclient now generates the correct value for the
  script environment variable, "expiry", the lease expiry value exceeds
  0x7FFFFFFF.  Prior to this such values would produce negative values
  for expiry in the script environment.
  [ISC-Bugs #43326]

- Common timer logic was modified to cap the maximum timeout values at
  0x7FFFFFFF - 1. Values larger than that were causing fatal timer out of
  range errors on 64-bit platforms. Thanks to Jiri Popelka at Red Hat for
  reporting the issue.
  [ISC-Bugs #28038]

- DHCP6 FQDN option unpacking code now correctly handles values that contain
  spaces, special, or non-printable characters.  Prior to this the buffer
  size needed was underestimated causing a conversion error message to
  be logged and DNS updates to be skipped. Thanks to Fernando Soto at
  BlueCat Networks for bringing the matter to our attention.
  [ISC-Bugs #43592]

- When running in -6 mode, dhclient can enforce the require option statement
  and will discard offered leases that do not contain all the required
  options specified in the client configuration.  If not enabled the client
  will still consider such leases.  This must be enabled at compile time
  (see ENFORCE_DHCPV6_CLIENT_REQUIRE in includes/site.h). Thanks to
  Mritunjaykumar Dubey at Nokia for reporting the issue.
  [ISC-Bugs #41473]

- Altered DHCPv4 lease time calculation to avoid roll over errors on 64-bit
  OS systems when using -1 or large values for default-lease-time.  Rollover
  values will be replaced with 0x7FFFFFFF - 1.  This alleviates unintentionally
  short expiration times being handed out when infinite lease times (-1) in
  conjunction with failover.  Our thanks to Alessandro Gherardi for bringing
  the issue to our attention.
  [ISC-Bugs #41976]

- Added new compile time option --with-srv-conf-file which specifies a
  default location of the server configuration file.
  [ISC-Bugs #44765]

- Added --dad-wait-time parameter to dhclient. It specifies the maximum time,
  in seconds, that the client process should wait for the duplicate address
  detection to complete before initiating DHCP requests. This value is
  propagated to the dhclient script and the script is responsible for waiting
  the specified amount of time or until DAD has completed. If the script does
  not support it, specifying this parameter has no effect. The default value
  is 0 which specifies that the script should not wait for DAD. With this
  change the following scripts have been modified to support the new parameter:
  freebsd, linux, macos, netbsd, openbsd.
  [ISC-Bugs #36169]

- The server nows checks both the address and length of a prefix delegation
  when attempting to match it to a prefix pool.  This ensures the server
  responds properly when pool configurations change such that once valid,
  "in-pool" delegations are now treated as being invalid.  During lease
  file loading at startup, the server will discard any PD leases that
  are deemed "out-of-pool" either by address or mis-matched prefix length.
  Clients seeking to renew or rebind such leases will get a response of
  No Binding in the case of the former, and the prefix delegation with
  lifetimes set to zero in the case of the latter. Thanks to Mark Nejedlo
  at TDS Telecom for reporting this issue.
  [ISC-Bugs #35378]

- Modified DDNS support initialization such that DNS related ports will only be
  opened by the server (dhcpd) at startup if ddns-update-style is not "none";
  by dhclient only if and when the it first attempts an update; and never by
  dhcrelay.  Prior to this all three always did the initialization at startup
  which causes them to always open on and listen for traffic on two random
  ports. Thanks to Rodney Beede for reporting this issue.
  [ISC-Bugs #45290]
  [ISC-Bugs #33377]

- Added error logging to two memory allocation failure checks. Thanks to Bill
  Parker (wp02855 at gmail dot com) for reporting the issue.
  [ISC-Bugs #41185]

- Corrected a dhclient -6 issue that caused the client to crash with an
  "Impossible condition" error after de-preferencing its only IA binding.
  The crash occurred when server configuration changes rendered the existing
  binding out-of-range and no other leases were available to offer. Thanks
  to Pierre Clerissi for bringing this issue to our attention.
  [ISC-Bugs #44373]

- By defining CALL_SCRIPT_ON_ONETRY_FAIL in includes/site.h, dhclient will
  now call the script with reason set to FAIL when run with -1 (one try) and
  there are no server responses.  This applies to IPv4 mode only. Thanks for a
  patch by Martin Pitt which got to us via Andrew Pollock.
  [ISC-bugs #18183]

- The server now detects failover peers that are not referenced in at least
  one pool when run with the command line option for test mode, -T.  Prior to
  this the check was performed too far down stream to be detected in test mode.
  [ISC-Bugs #29892]

- Linux script updated. The script is now based on Debian version. It uses
  ip tool from iproute2 package and ifconfig is no longer used. This also
  addresses an issue of calling arping with inappropriate parameter.
  [ISC-bugs #19430]
  [ISC-bugs #18111]

- Changed severity of the log message indicating UDP checksum errors in
  the received packets from 'info' to 'debug' to avoid logging excessive
  number of false positives when UDP checksum offloading is enabled.
  [ISC-bugs #41757]

- The directory minires has been removed from the source tree.  It has
  long been obsolete for branches other than v4_1_esv.  Additionally,
  includes/minires.h was renamed includes/ns_name.h.
  [ISC-bugs #45471]

- Replaced ifconfig parameters "add" and "delete" with "alias" and "-alias"
  for IPv6 mode in the client scripts, netbsd and openbsd.  This was
  preventing IPv6 addresses from being added or removed from interfaces.
  Thanks to Tim Dean for reporting this issue.
  [ISC-bugs #31573]

                        Changes since 4.3.5b1

- Corrected a bug which could cause the server to sporadically crash while
  loading lease files with the lease-id-format is set to "hex".  Our thanks
  to Jay Ford, University of Iowa for reporting the issue.
  [ISC-Bugs #43185]

- Eliminated a noisy, but otherwise harmless debug log statment that may
  appear during server startup when building with --enable-binary-leases
  and configuring multiple pools in a shared network.  Thanks to Fernando
  Soto from BlueCat Networks for reporting the issue and supplying a patch.
  [ISC-Bugs #43262]

                        Changes since 4.3.4

- Fixed util/bindvar.sh error handling.
  [ISC-Bugs #41973]

- Correct error message in relay to use remote id length instead
  of circuit id length.
  [ISC-Bugs #42556]

- Add logic to test directory Makefiles to avoid copying Attfile(s)
  when building within the source tree.  This eliminates a noisy but
  otherwise harmless error message when running "make check".
  [ISC-Bugs #41883]

- Leases are now scrubbed of certain prior use information when pool
  re-balancing reassigns them from one FO peer to the other.  This
  corrects an issue where leases that were offered but not used
  by the client retained the client hostname from the original
  client. Thanks to Pavel Polacek, Jan Evangelista Purkyne University
  for reporting the issue.
  [ISC-Bugs #42008]

- In the LDAP code and schema add some missing '6' characters to use
  the v6 instead of the v4 versions.  Thanks to Denis Taranushin for
  reporting this issue and supplying its patch.
  [ISC-Bugs #42666]

- Correct how the pick-first-value expression is written to a lease
  file.  Previously it was written as a concat expression due to
  a cut and paste error.
  [ISC-Bugs #42253]

- Modify the DDNS code to clean up the PTR record even if there
  are issues while cleaning up the A or AAAA records.
  [ISC-Bugs #23954]

- Added global configuration parameter, abandon-lease-time, which determines
  the amount of time a lease remains abandoned.  The default is 84600 seconds.
  Additionaly, the server now conducts a ping check (if ping checks are
  enabled) prior to offering an abandoned lease to client.  Our thanks to
  David Zych at University of Illinois for reporting the issue and working
  with us to produce a viable solution.
  [ISC-Bugs #41815]

- Correct handling of interface names during interface discovery. This
  addresses an issue where interface names of 15 characters in length
  could lead to crashes or interface recognition errors during startup
  of dhcpd, dhclient, and dhcrelay.
  [ISC-Bugs #42226]

- Updates to contrib/dhcp-lease-list.pl to make it more friendly.
  The updates are: looking for the lease file in more places and skipping
  the "processing complete" output when creating machine readable
  output.  Thanks to Cameron Paine (cbp at null dot net) for the
  patch.
  [ISC-Bugs #42113]

- When reusing a lease for dhcp-cache-threshold return the hostname
  to the original lease.  Also if the host pointer, UID or hardware address
  change don't allow reuse of the lease.
  Thanks to Michael Vincent for reporting this and helping us
  verify the problem and fix.
  [ISC-Bugs #42849]

- Change dmalloc to use a size_t as the length argument to bring it
  in line with the call it will make to malloc().
  [ISC-Bugs #40843]

- If the failover socket can't be bound, close it.  Otherwise if the
  user configures an incorrect address in the failover stanza the
  server will continue to open new sockets every 90 seconds until
  it runs out.
  [ISC-Bugs #42452]

- Add DHCPv4-mode, dhcrelay command line options, "-iu" and "-id", that
  allow interfaces to be upstream or downstream respectively.  Upstream
  interfaces will accept and forward only BOOTP replies, while downstream
  interfaces will accept and forward only BOOTP requests.
  [ISC-Bugs #41547]

- Clean up some memory references in the vendor-class construct.
  [ISC-Bugs #42984]

                        Changes since 4.3.4b1

- None

                        Changes since 4.3.3

- Corrected a static analyzer warning in common/execute.c
  [ISC-Bugs #40374]

- ISC DHCP now follows the common convention to use the base name a
  program is invoked with (aka argv[0], vs. a builtin name) for
  logs. This should help differentiate syslog entries for DHCPv4 and
  DHCPv6 servers. You can define OLD_LOG_NAME in includes/site.h to
  keep the previous behavior.
  [ISC-Bugs #38692]

- The Linux packet filter code now correctly treats only the least significant
  12 bits in an inbound packet's TCI value as the VLAN id (per IEEE 802.1Q).
  Prior to this it was using the entire 16 bit value as the VLAN id and
  incorrectly discarding packets.  Thanks to Jiri Popelka at Red Hat for
  reporting this issue and supplying its patch.
  [ISC-Bugs #40591]

- Fixed several static analysis issues such as potential null
  references, unchecked strdup returns.  Thanks to Bill Parker (wp02855 at
  gmail dot com) who identified these issues and supplied patches to
  address them.
  [ISC-Bugs #40754]
  [ISC-Bugs #40823]

- Corrected compilation errors that prohibited building the server
  and its ATF unit tests when failover is disabled.
  [ISC-Bugs #40372]

- Added the lease address to the end of the debug level log message
  emitted when an existing lease is renewed within the dhcp-cache-threshold.
  Thanks to Nathan Neulinger at Missouri S&T for suggesting the change.
  [ISC-Bugs #40598]

- Added dhcpv6 and delayed-ack to settings listed in the "Features:"
  section of the configure script output.  Additionally, all of the
  features reported on will now always show either a "yes" or "no"
  value.  Prior to this features left to their default setting would
  not show a value.
  [ISC-Bugs #40381]

- Added a parameter, authoring-byte-order, to the lease file. This value
  is automatically added to the top of new lease files by the server and
  indicates the internal byte order (big endian or little endian) of the
  server.  This permits lease files generated on a server with one form of
  byte order to be used on a server with the opposite form. Our thanks to
  Timothe Litt for calling this to our attention and for the suggestions
  he provided.
  [ISC-Bugs #38396]

- Fixed a small memory leak in the DHCPv6 version of the client code.
  This is unlikely to cause significant issues in actual use.
  [ISC-Bugs #40990]

- Corrected a few minor memory leaks in omapi's dereferencing of
  host objects. Thanks to Jiri Popelka at Red Hat for reporting
  the issue and supplying the patches.
  [ISC-Bugs #33990]
  [ISC-Bugs #41325]

- Cleaned up some of the Make infrastructure to make --with-libbind
  work better.  Though it still only works with an absolute path.
  [ISC-Bugs #39210]

- Made the embedded bind libraries able to be cross compiled
  (please refer to the bind9 documentation to learn how to cross
   compile DHCP and its bind library dependency).
  [ISC-Bugs #38836]

- Update the client code to better support getting IA_NAs and IA_PDs
  in the same packet, see RFC7550 for some discussion.
  [ISC-Bugs #40190]

! Update the bounds checking when receiving a packet.
  Thanks to Sebastian Poehn from Sophos for the bug report and a suggested
  patch.
  [ISC-Bugs #41267]
  CVE: CVE-2015-8605

- When handling an incorrect command line for dhcpd, dhclient or dhcrelay
  print out a specific error message about the first error in addition
  to the usage string.  This may be disabled by editing includes/site.h.
  [ISC-Bugs #40321]
  [ISC-Bugs #41454]

- The configure script will now exit with an error message if it cannot find
  a GNU-style make tool (needed when building BIND libraries) or pkg-config
  (needed to locate ATF used for building unit tests). Prior to this the
  script would exit indicating success causing subsequent attempts to build
  the software to fail.
  [ISC-Bugs #40371]

- Properly terminate strings before passing them to regex and fix
  a boundary error when creating certain new data strings.
  Thanks to Andrey Jr. Melnikov for the bug report.
  [ISC-Bugs #41217]

- Option expressions, such as prepend and append, are now supported when
  running dhclient for IPv6.  Prior to this such statements in the
  client configuration file would be parsed but have no affect.  Thanks
  to Jiri Popelka at Red Hat for reporting the issue.
  [ISC-Bugs #39952]

- A failover primary server will now accept a binding status update from the
  secondary which transitions a lease from ACTIVE to ABANDONED. This accounts
  for instances in which a client declines a lease and only the secondary
  server receives it.  Prior to this the primary server would reject such an
  update as an "invalid state transition".
  [ISC_BUGS #25189]

- Properly allocate memory for a bpf filter.
  Thanks to Bill Parker (wp02855 at gmail dot com) who identified this issue.
  [ISC-Bugs #41485]

- Updated contrib/dhcp-lease-list.pl to handle garbage in the oui file better
  and to print out the hostnames a bit better.
  Thanks to Antoine Beaupré from Debian for the suggested patch.
  [ISC-Bugs #41288]

- The DHCPv6 server now handles long valid and preferred lease times better.
  Values that would cause the internal end time of the lease to wrap are
  modified to work as infinite.
  [ISC-Bugs #40773]

- Updated support for cross compiling by allowing the library archiver
  to be set at configure time via the environment variable 'AR'.
  [ISC-Bugs #41536]

- The server will now match DHCPv6 relayed clients to host declarations
  which include the "hardware" statement, if the relay connected to the
  client supplies the client's hardware address via client-linklayer-address
  option as per RFC 6939.
  [ISC-Bugs #40334]

- Allow a filename to be specified instead of /dev/random during
  configuration.  This is passed to the BIND configuration to allow
  for cross compilation.
  [ISC-Bugs #33835]

- Add more option definitions.
  [ISC-Bugs #40562]

- Correct outputting of long lines in the lease file when writing
  a lease that includes long strings in an execute statement.
  [ISC-Bugs #40994]

- The server will now correctly treat a lease as reserved when the client
  requests an infinite lease time (i.e. OxFFFFFFFF) and "infinite-is-reserved"
  is enabled.  Prior to this the server would halt.  In addition, corrections
  were made to the server to allow a lease's flags field to be set via omapi.
  Prior to this, the server, depending on the host architecture,  would
  incorrectly parse the new flags value from the omapi message.
  [ISC-Bugs #31179]

- ISC DHCP can now be configured and built from a directory other than
  the top level source directory. Note that "make distcheck" uses this
  feature.
  [ISC-Bugs #39262]

- Add support for RFC 3527 to dhcrelay.  A new, dhcrelay command line argument,
  "-U <interface>" enables the addition of a RFC 3527 compliant link selection
  suboption to the agent option added for clients directly connected to the
  relay.
  [ISC-Bugs #34875]
  [ISC-Bugs #41708]

- Add a new global DHCPv6 option, dhcpv6-set-tee-times, which when enabled
  instructs the server to calculate T1 and T2 as recommended in RFC 3315,
  Section 22.4.
  [ISC-Bugs #25687]

- Corrected minor Coverity issues.
  [ISC-Bugs #35144]

- Add support for RFC 7341 DHCPv4 over DHCPv6 with a new configuration
  option "--enable-dhcpv4o6". Note this feature requires DHCPv6 support
  and is not compatible with delayed-ack. Both client and server use 2
  processes which communicate over UDP on a pair of sockets. The new
  "-4o6 <port>" command line argument enables DHCPv4 over DHCPv6 support
  and specifies the consecutive ports to use for inter-process communication.
  Please look at doc/DHCPv4-over-DHCPv6 for more details.
  [ISC-Bugs #35711]

- Correct interface name formation when using DLPI under Solaris 11. As of
  Solaris 11, ethernet device files are located in "/dev/net".  The configure
  script has been modified to detect this situation and adjust the directory
  used accordingly. Thanks to Jarkko Torppa for reporting this issue and
  submitting a patch
  [ISC-Bugs #37954]
  [ISC-Bugs #40752]

- Add a dereference call when handling an error condition while
  decoding a packet.
  [ISC-Bugs #41774]

- Add a new parameter, lease-id-format, to both dhcpd and dhclient. The
  parameter controls the format in which certain values are written to lease
  files.  Formats supported are octal - quoted string containing octal
  escapes, and hex - unquoted, colon separated hex digits.  Thanks to
  Jay Ford, University of Iowa for bringing the issue to our attention.
  [ISC-Bugs #26378]

! Add an option in site.h to limit the number of failover and control
  connections the server will accept.  By default this is 200.
  [ISC-Bugs #41845]
