1.0.8 - Unreleased

New features

Fixes

Changes for users

Changes for developers

1.0.7 - 2017-06-25

Fixes

  • Fix Debian and RPM dependencies
  • Fix unnecessary dependency on newer version of pkg_resources

1.0.6 - 2017-06-25

Fixes

  • Fix calculations of maximum domain name length
  • Deal with the release of ZConfig 3.2.0, which broke our ZConfig 3.1.0 previous hacks

Changes for users

  • Switch to idna with better IDNA implementation (it implements 5891 instead of the obsolete 3490)

Changes for developers

  • normalise_hex now accepts bytes as input, for easier byte printing

1.0.5 - 2017-06-21

New features

  • Provide RPM repositories at https://repo.dhcpkit.org/
  • Add PD-Exclude option implementation
  • Add Client FQDN option implementation
  • Add Timezone options implementation
  • Add Relay Echo-Request option implementation
  • Add Relay Echo-Request option handler implementation

Fixes

  • Fixed Python type annotations in many places

Changes for users

  • Show LDRA relays when printing .TransactionBundle
  • The DHCPv6 server will try to keep going when not running as root, it might sometimes work, for example when connecting to a VPP instance instead of the usual opening listening sockets on low ports

Changes for developers

  • Improve DNS handling: be explicit about difference between absolute and relative domain names
  • New .UnknownProtocolElement available for more generic protocol parsing
  • .All_DHCP_Relay_Agents_and_Servers and .All_DHCP_Servers are now instances of IPv6Address instead of strings
  • Added an .IgnoreMessage exception type so listeners can signal to the server that the received data is to be ignored
  • The .IncompleteMessage exception is now a subclass of .IgnoreMessage

1.0.4 - 2016-12-17

New features

  • Provide debian/ubuntu packaging with init/init.d/systemd scripts
  • Provide an extensive default configuration
  • Allow the control socket location to be overridden from the command line

Fixes

  • Improve ipv6-dhcpd to ipv6-dhcpctl communication when shutting down
  • Add missing copyright statement for RFC 7598
  • Fix Sphinx RFC reference

Changes for users

  • Allow unicast listening on ::1 for testing purposes

Changes for developers

  • Make python dependencies more accurate
  • Make building process for documentation more stable

1.0.3 - 2016-11-17

Fixes

  • Fix leasequery statistics output, also fixes Observium stats

1.0.2 - 2016-11-16

Why?

  • Re-release with updated changelog and status

1.0.0 - 2016-11-16

New features

  • Add rate limit handler to ignore obnoxious clients
  • Add implementation for the Leasequery and Bulk Leasequery protocols

Fixes

  • Ignore MAC address 00:00:00:00:00:00 when searching for a server-id
  • Fix finding the inner relay message in a RelayForwardMessage

Changes for users

  • Improve logging for ignored messages
  • The default log level now only logs errors, not warnings
  • Improve exception handling and logging for errors during worker initialisation

Changes for developers

  • Sending replies has been moved from the main process to the worker processes
  • Therefore .OutgoingPacketBundle does no longer exist
  • Constants for status codes have been renamed to be more consistent, the old names have been deprecated and will be removed in the future
  • Tests have been moved under the dhcpkit module to be easier to import from other extensions (for example when they need a solicit message and packet to test with)
  • Added Leasequery and Bulk Leasequery messages, options and status codes
  • Leasequery needs RelayForwardMessages without a contained message, so allow that now
  • Code for privilege management have been moved to dhcpkit.common
  • Code for console logging has been moved to dhcpkit.common.logging
  • Replies are now sent directly from worker processes, not first handed back to the master and then sent from there
  • Refactor listeners and message handling to allow for TCP listeners and leasequery extensions
  • Open sockets with SO_REUSEADDR so we can restart quickly without having to wait for TIME_WAIT
  • Allow for multiple responses in transaction bundle, especially useful for TCP connections

0.9.5 - 2016-08-11

New features

  • 2.5x speed improvement.

Changes for developers

  • .ProtocolElement.parse and the ~.ProtocolElement.load_from methods it uses no longer call .ProtocolElement.validate because every (nested) element validating everything all the time is rather inefficient. Now callers are supposed to call .ProtocolElement.validate themselves (if they want to).
  • We no longer use abc and ~abc.ABCMeta. It turned out that all the run-time validation it did caused a ±20% slow down.

0.9.4 - 2016-08-04

New features

  • Added support for the 6939 client link-layer address relay option
  • Added support for the 4580 subscriber-id relay option
  • Added support for the 6334 DS-Lite AFTR tunnel endpoint name option
  • Added support for the 7598 MAP options
  • Added support for ~dhcpkit.ipv6.extensions.linklayer_id and ~dhcpkit.ipv6.extensions.subscriber_id in static-csv and static-sqlite

Fixes

  • Fix error where command line log-level argument was ignored.
  • Fix error that caused every message to be interpreted as received-over-multicast
  • Don't block when the inbound queue is full, just drop the message and continue
  • Fixed an interface-id parsing bug in static-csv and static-sqlite
  • Allow UnknownOption in all options, otherwise we reject messages with options that contain unknown sub-options

0.9.3 - 2016-07-27

Fixes

  • Not all systems have a wheel group anymore, so don't use that as a default group for the control socket.
  • Linux doesn't support SIGINFO, and its functionality has become redundant with the new control socket functionality, so remove SIGINFO handling.

Changes for users

  • Critical errors are now always shown on stderr. Otherwise the server could crash without the user seeing the reason.

0.9.2 - 2016-07-27

Fixes

  • A packaging error slipped through the checks, and it turns out that crucial XML files weren't packaged in previous 0.9.x versions. This has now been fixed.

0.9.1 - 2016-07-27

New features

  • It is now possible to use IDNs everywhere in DHCPKit, including configuration files.
  • Implement a domain socket to control the server process.
  • Added ipv6-dhcpctl to control the server process through the domain socket.
  • Added a configuration section <statistics> to specify categories that you would like statistics on. Currently it is possible to gather statistics per interface, client subnet or relay.
  • Added stats and stats-json commands for ipv6-dhcpctl.

Changes for users

  • Create PID file /var/run/ipv6-dhcpd.pid by default.
  • Create domain socket /var/run/ipv6-dhcpd.sock control the server by default.

Changes for developers

  • Added support for Internationalized Domain Names (IDN) in ~dhcpkit.utils.parse_domain_bytes and ~dhcpkit.utils.encode_domain.
  • Created ForOtherServerError as a subclass of CannotRespondError, to enable more accurate logging, and to make it possible to gather better statistics.
  • Replaced .IncomingPacketBundle.interface_id bytes with ~.IncomingPacketBundle.interface_name str, providing ~.IncomingPacketBundle.interface_id for backwards compatibility.
  • Added ~.TransactionBundle.relays property to more easily enumerate all the relays a message went through.
  • Moved responsibility of creating the .TransactionBundle from the .MessageHandler to .worker. It gives a cleaner API and helps with statistics counting.
  • Added .statistics and updated .worker and .MessageHandler to update relevant counters.

0.9.0 - 2016-07-16

  • A complete rewrite of the DHCPv6 server with a new configuration style.
