Subject: [kea-dev] Kea 1.2.0-beta released!
Message-ID: <[email protected]>
Content-Type: text/plain; charset=utf-8
On behalf of ISC and Kea team I'm pleased to announce that new version
of Kea is now available for testing! Kea 1.2.0-beta is can be downloaded
from:
https://www.isc.org/download
final version will be released at the end of this month - April 28, 2017.
Kea 1.2.0-beta Release Notes:Kea is a new DHCP implementation
being developed by Internet Systems Consortium, Inc. that features fully
functional DHCPv4 and DHCPv6 servers, a dynamic DNS update daemon, a Control
Agent (CA) that provides REST API to control DHCP servers, an example shell
client to connect to the CA and a DHCP performance measurement tool. Both DHCP
servers fully support server discovery, address assignment, renewal, rebinding,
release, decline, information request, DNS updates, client classification and
host reservations. The DHCPv6 server also supports prefix delegation. Lease
information can be stored in a MySQL, PostgreSQL or Cassandra database; it can
also be stored in a CSV file. Host reservations can be stored in the
configuration file; they can also be stored in a MySQL or PostgreSQL database.
Version 1.2.0-beta adds the following features to Kea:
* Control Agent - is an optional daemon that can connect to command channels
exposed by DHCPv4 and DHCPv6 (this capability in DDNS module is coming soon)
and exposes it over REST API. It uses a clean, easy to use HTTP interface
that
receives commands defined in JSON syntax. A number of existing commands are
available, with more being planned for each upcoming releases.
* kea-shell is an example client that can connect to CA. It is a tool that is
mostly intended to be used in scripts, but can also be used to send commands
manually. It is written in Python (supports both 2.x and 3.x), is optional
(no
python needed by default) and serves as an illustration on how to take
advantage of the REST API. Any software or environment that can form JSON
commands and send them over an HTTP interface can take advantage of the new
API.
* parser refactoring - Part of the Kea code that was responsible for
understanding configuration files was very complex, difficult to understand
and
even more difficult to extend. With the introduction of the REST API and its
new commands, new use cases appeared when a file on disk is not the only
possible source of configuration. Therefore the Kea team spent significant
effort to refactor configuration handling. The code is now much leaner,
simpler
and much more extensible. There are some user visible benefits, too: you can
now use C++ (!//) and C (/* ... */) comments everywhere. C style comments can
span multiple lines. It is also now possible to include other files in your
configuration file. The default values for absent parameters are now clearly
defined and many additional sanity checks have been implemented. Finally, the
configuration error messages are now more descriptive and easier to
understand.
* new commands - a number of new commands have been implemented. In particular,
it is now possible to update (config-set), retrieve (config-get) or write the
current configuration to disk (config-write). It is possible to list
supported
command (list-commands), check version (version-get) information or
compilation
details that cover dependencies versions (build-report) and more. Commands
previously available only over command channel API are now also available
over
REST API.
* configuration test - A capability to test new configuration has been added.
This works both from the command-line (see -t switch), via REST interface and
command channel API (see config-test command).
* options in pools - It is now possible to specify options on a pool level.
* C++11 - Kea 1.2-beta is the first Kea release that requires C++11 support in
your compiler.
* Overall 113 tickets and 15 pull requests on github have been closed.

option, field, characteristic or property of the packet to be
used as identifier and then do reservations based on the evaluated
expression for each incoming packet.
(Trac #5132, git cd497526d5bff7ae55bb41c9264fb33943a0cf62)

provided by Control Agent, has been added. Control Agent now
uses bison parser, which provides better sanity checks, improved
comments and file inclusions.

store it in its configuration syntax structure. Upcoming tickets
will take advantage of that information.
(Trac #5134, git 828304f2f408888e4b096418e90e35ba524979d0)

and the SimpleParser framework. This includes changes to
libprocess which render the CPL agnostic to the underlying
parsing mechanisms.
(Trac #5110, git feb2cedc0936364a923ab78542a21114533dd0f5)
1217. [func] marcin

1216. [func] fdupont, tomek
Command line option -t implemented for DHCPv4 and DHCPv6. It
allows configuration sanity checking. Note that not all parameters
are completely checked. In particular, service and control channel
sockets are not opened, and hook libraries are not loaded.

is not used yet.
(Trac #5076, git d99048aa5b90efa7812a75cdae98a0913470f5a6)
1213. [bug] fdupont

SimpleParser framework. Several parameters (renew-timer,

(Github #32, git d51c005519c4add6fd0c37bcd68b0fbe94941b2d)
1187. [bug] marcin
DHCPv4 server allows for allocating multiple leases for the
same hardware address if a different client identifier is
used for each lease. This facilitates the PXE boot use cases
where a booted machine may request a lease multiple times.
(Trac #5029, git 03defed4d8bb9a997d31dbfcf30ae3f866bd3353)

1183. [bug] tmark
kea-dhcp4 now correctly loads declined leases from CSV
lease files. Prior to this, declined leases were being
incorrectly and silently discarded. In addition, both
kea-dhcp4 and kea-dhcp6 will now emit an error log for
each invalid row encountered when loading leases from
CSV files.
(Trac #5058, git 29b088079bed3c5059fdf8a43a4e79cd7f9a4207)
