ChangeLog

841.	[func]		tomek
	Pkt4 and Pkt6 class have a common base now. A lot code duplication
	removed. Added getMAC() method that will be used to extract MAC
	in DHCPv6.
	(Trac #3546, git 6e68af7dfe15e4d461bf068f545d2bdaaa8fcfb0)

840.	[func]		nicolas
	PktFilterInet::send method now sets source IPv4 address explicitly.
	This enabled perfdhcp to control its source address on systems that have
	more than one address assigned to a given interface. Thanks to
	Nicolas Chaigneau from Capgemini for providing this fix.
	(Github #2, git 6ac36ed7a1d97bcf52ffb2aec7cbf116e58e5803)

	DHCPv4 examples corrected in Kea ARM. Thanks to Adam Osuchowski
	from Silesian University of Technology for providing this fix.
	(Github #1, git 15785c0e28190659b037cfcca19f0267ccd9049f)

838.	[bug]		tomek
	Kea components now use the KEA_LOCKFILE_DIR environment variable
	to specify the directory of the logging lockfile. Locking can be
	disabled completely by setting the variable to 'none'.
	(Trac #3591, git d4556e1d21766b94f2f0cda59df15e47e6f2676e)

	The configure script checks if OpenSSL supports SHA-2, in order
	to avoid very old (and likely subject to unfixed security bugs)
	OpenSSL versions.
	(Trac #3482, git c779a0ef23d2092cf896276dab1fbcb190380374)

	pools in the default kea.conf file.

833.	[func]		marcin
	Configuration Manager supports two stage configuration. In the
	first stage a temporary configuration is created and in the
	second stage this configuration is committed. If configuration
	fails at the first stage, the temporary configuration is rolled
	back and the server continues to use the old configuration.

	DHCP servers check if the interfaces specified in the configuration,
	to be used to receive DHCP messages, are present in the system.
	If the interface doesn't exist, an error is reported. In addition,
	the SO_REUSEPORT flag is set for IPv6 sockets as multiple multicast
	sockets can be bound to the DHCPv6 server port.

Kea 0.9beta1 released on August 13, 2014

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.

803.	[func]		marcin
	DHCPv4 server supports responding to directly connected clients on
	FreeBSD, NetBSD and OpenBSD using Berkeley Packet Filtering. This
	also resolves the problem reported in #3438 that the server doesn't
	pick the correct interface to respond to the client and the client

800.	[bug]		marcin
	DHCPv6 server is now usable on FreeBSD, NetBSD and OpenBSD systems.
	It can receive messages sent to ff02::1:2 multicast address. Also,
	fixed the bug whereby the DHCPv6 server failed to bind the socket
	to global unicast address on BSD systems due to invalid scope id
	setting.

	Removed a lot of remaining BIND10 framework: bind10, bindctl,
	cfgmgr, cmdctl, msgq, stats, sysinfo, tests, usermgr from src/bin
	directory, also src/lib/python directory. Python3 is not
	required anymore, unless documentation generation is enabled.

	cryptolink: add OpenSSL crypto backend as an alternative to Botan

	DDNS, removing the Botan dependency.

	DHCP-DDNS: Implemented dynamic reconfiguration of the server,
	triggered when the SIGHUP signal is received by the server's
	process. Also, server performs a graceful shut down when SIGINT
	or SIGTERM signal is received.
	(Trac #3407, git f1a224df1e46098748ba60205be09ada4600515f)

	servers and get their status and configuration data. This script
	is installed only if the JSON configuration backend is in use.

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.

	libdhcpsrv: the Memfile lease storage backend now writes
	leases into a CSV file. Configuration parsers for b10-dhcp4

	b10-dhcp4 and b10-dhcp6 now support using PostgreSQL as the backend
	for storing lease data.  This backend is enabled by specifying
	--with-dhcp-pgsql on the "configure" command line. Without this
