On behalf of ISC and Kea team I'm pleased to announce that
new version 1.6.0 beta is released and available to use!
Welcome to Kea 1.6.0-beta. Kea is a DHCP implementation 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 a REST API to control the DHCP and DNS update servers, an
example shell client to connect to the CA, a daemon that is able to
retrieve YANG configuration and updates from Sysrepo, 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 is stored in a CSV file by default; it can optionally be
stored in a MySQL, PostgreSQL, or Cassandra database instead. Host
reservations can be stored in a configuration file; they can also be
stored in a MySQL, PostgreSQL, or Cassandra database and, to some
degree, retrieved from a RADIUS server. Kea DHCPv4 and DHCPv6 daemons
provide support for YANG models, which are stored in a Sysrepo datastore
and can be configured via the NETCONF protocol.
The text below references issue numbers. For more details, visit the Kea
GitLab page at https://gitlab.isc.org/isc-projects/kea/issues. The major
new features and changes in this version are:
1. **Config Backend**. Kea Configuration Backend (abbreviated as Config
Backend or CB) is a new feature which lets the DHCPv4 and DHCPv6 servers
manage and fetch their configuration from one or more MySQL databases.
The MySQL CB implementation is distributed as a hooks library. You can
now store most of the Kea configuration in the CB: global parameters,
shared networks, subnets, pools, options, and option definitions.
Instead of specifying these parameters in your local configuration, you
can now put this information in the database and simply tell Kea where
to find it. Kea will merge the parameters from the CB with other
parameters configured locally (such as interfaces). Kea can
periodically poll the CB and retrieve updates. This will greatly
simplify automated configuration change deployments.
The most basic configuration for CB looks more or less like this:
The CB is supported for DHCPv4 and DHCPv6. The only database supported
for now and the near future is MySQL.
You can connect multiple Kea instances to retrieve configurations from
the same central database; this lets you effectively centralize your Kea
servers' configuration and push configuration changes to all your Kea
This 1.6.0-beta version supports only a single Kea configuration per
configuration backend. During the beta period we will add server tags,
where you will be able to specify that certain configuration elements
(such as a specific subnet) should be applied only on servers with a
matching server tag. This will let you differentiate configurations
between servers while keeping all configuration elements in the same
centralized database. In future releases (1.7.0 and beyond) we will
continue improving and expanding this mechanism. The improvements will
likely include adding more capabilities for configuration in database
storage, such as client classes, hooks, logging, and network interfaces.
The CB is implemented for MySQL only. This is a conscious decision; we
hope to polish the feature's rough edges on one specific backend before
we implement it for other databases. It is somewhat likely that
PostgreSQL will appear sometime in the future, but that will happen only
when the MySQL-based CB is mostly complete. Unfortunately, due to
Cassandra's nature as a non-relational database and the difficulty
working with it, it is unlikely we will ever implement a CB for
The config backend is by far the most complex feature ever developed in
Kea and we ask for your honest feedback on it. Did you manage to get it
working? What was easy and what was difficult or not working? What are
the features you'd like to see next?
2. **Management commands for the Config Backend**. The CB stores data in
a MySQL schema that is public. It's possible to insert a configuration
into the MySQL tables manually, or automatically using SQL scripts, but
this requires a reasonably good knowledge of the schema. As an
alternative, ISC has developed a new hook library that provides
management commands for config backends. It simplifies many typical
operations, such as listing, adding, retrieving, deleting of global
parameters, shared networks, subnets, pools, options, and option
definitions. For a complete list, see commands starting with "remote-"
in [Appendix A of the Kea User's
The cb_cmds hooks library is available to subscribers only. If you are
not a subscriber and would like to participate in beta testing, please
contact [hidden email] and our sales team will assist you.
3. **Native packages**. As we continue its development, Kea is adding
integration with other open source products, including NETCONF (provided
by Sysrepo), RADIUS (based on the FreeRADIUS client), and Cassandra.
That flexibility comes at a price, though. It is getting more difficult
to install Kea with those optional dependencies enabled. We also noticed
that some OS distributions lag behind in packaging the latest Kea
releases. To help alleviate both of those problems, ISC will start
providing our own native (DEB and RPM) packages for several popular
distributions. We are planning to provide packages for CentOS 7, Debian
9, Fedora 28 and 29, and Ubuntu 18.04, 18.10 and 19.04. The binary
packages will cover DHCPv4, DHCPv6, DDNS, Control Agent, and all three
(MySQL, PostgreSQL, Cassandra) backends. ISC subscription customers will
also be given an option to conveniently install hooks as separate
packages. In the future we plan to experiment with packaging NETCONF
with Sysrepo and all its necessary dependencies. The native packages
will be available within four weeks after 1.6.0-beta sources become
available; stay tuned for a separate announcement!
4. **Improved compatibility**. Kea follows RFC standards as defined by
the IETF; however, there are some devices out there that are not as
strict in following the standards. Nevertheless, Kea should be able to
work with such devices. Kea 1.6.0 now sends the DHCPv4 message type as
the first option (#530), the trailing null is now stripped from received
options (#539), empty hostnames are handled better (#40), and it's now
possible to define sub-options with codes 0 and 255 (#564).
5. **Control socket for DDNS**. The DDNS daemon has finally gotten its
control socket and can process commands. It's now possible to update its
configuration and in general interact with it while it's running. The
following nine commands are now supported: build-report, config-get,
config-reload, config-set, config-test, config-write, list-commands,
shutdown, and version-get (#30).
6. **Preliminary performance improvements**. While overall performance
improvements will be the major focus of the next Kea release, we
conducted some preliminary work in 1.6. Perfdhcp, a tool for testing
performance, is now multi-threaded (#283) and has a new 'avalanche' mode
to simulate a large number of devices renewing at once. It lets you
measure how long it takes to provision a specified number of devices,
with a realistic model of devices getting impatient and retransmitting
when not provided with an answer within one second. Also, Kea DHCPv4 can
now be configured to disable client-id lookup in a database to speed up
7. **Performance reports**. ISC has started publishing performance
reports. The two documents available now are [Performance report
comparing 1.4.0 and
8. **New host cache commands**. Two new commands have been implemented
in the host cache hook: cache-size (which lets you check the current
number of cached entries) and cache-get-by-id (which lets you look up
whether an entry for a specified hardware address, client-id, duid,
circuit-id, or flex-id is in the cache) (#594).
9. **New subnet commands**. Two new commands were added to the
subnet_cmds hook: subnet4-update and subnet6-update. They allow the
existing IPv4 and IPv6 subnets to be tweaked (#465). Previously in order
to update an existing subnet you had to first remove it and then re-add
it with the changes.
10. **New host commands**. Two new commands were added to the host_cmds
hook. They allow retrieval of all reservations from a given subnet,
either in one go (reservation-get-all) or page by page
(reservation-get-page) (#313, 511).
11. **High Availability improvements**. Two improvements have been made
in the High Availability code. First, it better handles abrupt time
changes, e.g. when NTP changes the system clock (#599). Second, the CA
daemon now adds Host http header, which makes it possible to set up a
reverse HA proxy with NGINX (#360).
12. **Logging moved** to daemon scope (#273). Earlier Kea versions had
the Logging scope defined at the global level in their JSON
configurations, due to historical reasons that no longer apply. The idea
was to have one configuration file shared by all daemons, but it didn't
withstand the test of time. Kea 1.6.0 moves the Logging entry to
specific scopes, such as Dhcp4 or Dhcp6. For the time being, Kea 1.6.0
still accepts the old syntax, but prints a warning. Future Kea versions
will eventually drop that backward compatibility and will produce an
error. Make sure you update your configurations.
13. **Automatically calculate renewal and rebind timers** (#365).
Earlier Kea versions had the renewal (t1) and rebind (t2) timers
configured manually with their own defaults. These were simple mechanics
that worked in general, but it was too easy to inadvertently
misconfigure Kea. It is now possible to tell Kea to automatically
calculate t1 and t2 times based on valid (v4) or preferred (v6)
lifetimes. See the 'calculate-tee-times', 't1-percent', and 't2-percent'
parameters for details.
14. **Hook libraries moved to separate directory**. Earlier Kea versions
installed hooks in a /usr/lib/hooks/ directory. This was confusing as
the /usr/lib/ directory is shared by all software installed on the
system and it was unclear what the hooks meant. The directory is now
called /usr/lib/kea/hooks. When upgrading to 1.6.0 make sure you update
your configuration to point to the right hook libraries (#161).
15. **Hammer added**. ISC developed a tool that is used internally to
build VMs and install Kea dependencies on many systems. We thought that,
while the tool is not intended for end-users, there may be power users
that could benefit from having access to such a tool. It is not part of
the tarball release, but it may be retrieved from our GitLab repository
16. Many small **fixes related to recent OS releases**: NetBSD 8.0
(#165), Fedora 29 (#354), FreeBSD 11.2 (#367), CentOS 7 (#380),
macOS/XCode (#561), Ubuntu 19.04 (#589), and installation on Debian 9
with MariaDB 10.1 (#389).
17. **RADIUS improvements**. RADIUS has gotten a round of improvements:
a memory leak has been fixed (#415), accounting is now better documented
(#416), and RADIUS with shared networks works much better (#474).
18. **Cassandra consistency** is now a configurable parameter (#16).
19. **Kea can recalculate statistics** when the server configuration
changes (#394). This addresses a problem when statistics were reflecting
an old configuration and didn't take into account configuration changes
since the last full server reconfiguration.
20. **Better debugging of flex-id** for non-printable characters (#21).

The configuration syntax has changed. The Logging scope that used
to be shared between all servers has been deprecated. Each daemon

deprecated. Kea 1.6 will accept it, but that capability will be
removed in the future. Please migrate your configuration to new

1542. [test] tmark
MySQL, PostgreSQL, and CQL unit tests will now attempt to wipe
the unit test data, rather than the (re)create the schema between
each test. This reduces test execution time appreciably. The
behavior may be overridden by defining environment variable:
KEA_TEST_DB_WIPE_DATA_ONLY="false". This will cause the schema
to be recreated before each test but may dramatically increase
test execution time.

Improved handling unix sockets in unit tests. Now by default
they are created in temporary folder under /tmp folder. This
fixes the issue with creating sockets with too long path
in the case when source folder is deeply nested.

Renamed OptionalValue C++ object to Optional and modified its
API. This object is now used to represent optional values in
subnets and shared networks. This is an internal Kea logic
change but it may impact existing user hooks libraries.

Support for vendor options improved in DHCPv4 and DHCPv6. Kea is
able to send back vendor suboptions, even if the client packet
include DHCPv4 vivso (125) or DHCPv6 vendor (17) option. Usage
classification in such a case is required, though.

1522. [bug] marcin
The "unspecified" DHCP timer values (e.g. renew-timer) are
represented as NULL values in the database. This corrects
a bug whereby the unspecified timers defaulted to 0 which
prevented the DHCP server from calculating the timers to
be sent to the client. Instead a value of 0 was sent.

1521. [func] marcin
Removed subsecond precision for the timestamps in MySQL config
backend. It caused issues on systems with MySQL version prior
to 5.6.4 which don't support subsecond timestamp values.

always local has been fixed. Thank you to Brent Bloxam from
Beanfield Metroconnect for submitting a patch!

Extended MySQL schema to include the types of the global DHCP
parameters in the database. The Kea servers will use this
information to cast the values fetched from the database into
their actual types. The supported types are: string, integer,
boolean and real.

kea-dhcp4 will now connect to and fetch configuration data from
configured backends. At this point, only fetched subnet data is
merged and used.

Implemented audit trail for MySQL Configuration Backend. It
for tracking incremental changes in the servers' configurations.
Both mysql_cb hooks library and the MySQL schema have been
to facilitate this feature.

Changes required for new host commands that retrieve all host
reservations from a given subnet (reservation-get-all,
reservation-get-page) added. Also added documentation.

Control Agent and DHCP-DDNS daemons now support config-reload
command, that instruct a given server to load again its
configuration from a file on disk.

Fixed perfdhcp that now it keeps requested rate during
testing. Previously it was always about 20% lower than expected.

1512. [func] tmark
kea-dhcp4 will now ignore empty Host Name (option code 12) values
received from clients. While an empty value for this option is
not RFC-compliant, some clients do send them. Prior to the this
server would drop the entire packet. In the spirit of being
in what we accept, the server will now simply omit the option.

kea-dhcp4 can now be configured to calculate values to
send to clients for for T1 and T2 (options 58 and 59
repsectively). Prior to this it was only possible to
specify explicit values.

1508. [func] fdupont
Implemented the management API using a control socket for the
DHCP DDNS (D2) server. D2 now supports the following commands:
build-report, config-get, config-set, config-test, config-write,
list-commands, shutdown and version-get. Also, extended Control
Agent (CA) to support one additional command: config-set.
(Gitlab #30,!183, git ab27550cec365f42289eb5fa1bc39f33f01b19c2)
1507. [func] tmark
kea-dhcp4 now ensures that the message type option (53) is
the first option in outbound DHCPv4 packets. This was done
to accommodate non-compliant clients that require the option
to be first.
