This is the first beta of the upcoming 0.9 release of Kea. Kea is
a new DHCP implementation being developed by Internet Systems
Consortium, Inc. that features fully functional DHCPv4, DHCPv6 and
Dynamic DNS servers. Both DHCP servers fully support server discovery,
address assignment, renewal, rebinding and release. The DHCPv6
server supports prefix delegation. Both servers support DNS Update
mechanism, using stand-alone DDNS daemon, which is part of the
release.
Kea 0.9 brings in notable changes. The most prominent one is a
removal of the BIND10 framework and all DNS components that were
not useful for DHCP operation. Kea is now a pure C++ solution
without Python dependencies. keactrl, a shell script, has been
added to control Kea daemons operation. The configuration process
has changed as well. The configuration is now stored in JSON files
that are loaded at start-up. Servers can be instructed (using POSIX
signals) to reload their configuration without any restarts. Kea
temporarily lost the capability to have its configuration updated
remotely. There are plans to restore that capability in the upcoming
releases. Note for migrating from Kea 0.8 to 0.9, the JSON-based
configurations need to be updated.
Support for OpenSSL has been added. During compilation time, Kea
requires just one cryptographic library to be present: either Botan
or OpenSSL.
DDNS now supports cryptographic signatures (TSIG). HMAC-MD5,
HMAC-SHA1, HMAC-SHA224, HMAC-SHA256, HMAC-SHA384 and HMAC-SHA512
can be used.
DHCPINFORM (DHCPv4) and Confirm (DHCPv6) messages are now supported.
Support for FreeBSD, NetBSD and OpenBSD has been added. The code
should also work on Mac OS X, but it was not tested.
This release also features a significantly revamped Kea Administrator
Reference Manual and example configuration files. The number of
examples is currently small, but there are plans to expand the
collection in the near future.
The kea-0.9-beta1 source may be downloaded from:
ftp://ftp.isc.org/isc/kea/0.9-beta1/kea-0.9-beta1.tar.gz
A PGP signature of the distribution is at
ftp://ftp.isc.org/isc/kea/0.9-beta1/kea-0.9-beta1.tar.gz.sha512.asc
The signature was generated with the ISC code signing key which is
available at https://www.isc.org/about/openpgp
Kea provides detailed documentation, including installation
instructions and usage tutorials. In addition, all logging messages
have unique documented explanations. This documentation is included
with the installation or via http://kea.isc.org/docs/ in HTML,
plain text, or PDF formats. We also maintain a public open source
code tree and wiki pages with roadmap and issue tracking at
http://kea.isc.org/.
Limitations and known issues with this DHCP release can be found
at http://kea.isc.org/wiki/KeaKnownIssues
We'd like testers of this beta release to please let us know how
it worked for you and what operating system you tested on. Feel
free to share your configuration or use case. Also we would like
to hear whether the documentation is adequate and accurate (please
open tickets for documentation omissions and errors). We want to
hear from you even if everything worked.
If you have any comments or questions about working with Kea, please
share them to the Kea Users List
https://lists.isc.org/mailman/listinfo/kea-users or to the Kea
Jabber room. Bugs and feature requests may be submitted via the
ticket tracking system at http://kea.isc.org/.
The following summarizes the significant changes and important
upgrade notes since the previous release (BIND 10 Kea 0.8). (See
the git history for more details and additional development.)
819. [build] marcin
Renamed variables in the configure.ac so as their names do not
refer to BIND10 project. As a result of renaming the B10_CXXFLAGS
to KEA_CXXFLAGS in configure.ac all dependent Makefiles had to
be updated in the tree. The AX_BOOST_FOR_BIND10 macro has been
renamed to AX_BOOST_FOR_KEA.

status of the DHCP-DDNS server.
(Trac #3465, git 6bc61470c9ccee001fe282d0f879bcddac0b8721)
794. [func] fdupont
cryptolink: add OpenSSL crypto backend as an alternative to Botan
by specifying --with-openssl[=PATH] on the "configure" command
line. Add hash support to the cryptolink API and use it in DHCP
DDNS, removing the Botan dependency.

servers and get their status and configuration data. This script
is installed only if the JSON configuration backend is in use.
(Trac #3422, git e1d164c7a9a54a7aacea88c8c57cd2826e06012b)
791. [func] tmark
DHCP-DDNS: Now supports configure.ac parameter: --with-kea-config.
It allows selecting configuration backend and accepts one of two
values: BUNDY, which uses Bundy (former BIND10) framework as Kea
0.8 did, or JSON, which reads configuration from a JSON file.

DHCP-DDNS now supports DDNS updates with TSIG. Please refer to the
Kea Guide for details. Prior to this TSIG keys could be defined but
were not used.
(Trac #3432, git 80fea12a53d1e832d4e7b710ca6ea613300f73ea)
785. [bug] marcin
DHCPv6 server avoids collisions between prefixes that are allocated
as a result of receiving hints from the clients. Previously the
whole prefix (including bits beyond the prefix length) was used to
search existing leases in the lease database. If not found, the
new lease was crated for the prefix sent by the client. If another
client sent the same prefix but with different non-significant bits
the prefix was allocated. This led to prefix collisions. Currently,
server ignores bits beyond the prefix length when searching for
existing leases.
(Trac #3246, git 50de7df4195195e981ae9c8c6f1b4100047d5bb5)
784. [func] tmark
DHCP_DDNS's configuration was changed. The unused parameter,
"interface" was deleted. Three new parameters, "ncr_protocol",
"ncr_format", and "dns_server_timeout" were added. Please refer to
Kea Guide for details.

libkea-dhcpsrv: the Memfile lease storage backend returns leases
of a specified type. Previously, it ignored the lease type parameter
and returned all leases for a particular client. Thanks to David
Carlier for helping to implement this ticket.
(Trac #3148, git d2f0edf473716cd747a21d6917e89ba55c148d8e)
780. [func] marcin
libkea-cc: JSON parser stores information about the position
of the data element values in the JSON string. The position
comprises the line number and the offset within this line where
the specific value resides. This functionality is intended to
be used for error logging during configuration parsing.
(Trac #3408, git 115a52a6713340fc589f6f95d73d242931239405)
779. [doc] tmark
Added a section to the developer's guide for Kea's DHCP-DDNS
component, D2.
