ChangeLog

755.	[func]		muks
	Add support for the CAA RR type (RFC 6844).
	(Trac #2512, git 39162608985e5c904448f308951c73bb9c32da8f)

754.	[func]		muks
	Add support for the TLSA RR type (RFC 6698).
	(Trac #2185, git a168170430f6927f28597b2a6debebe31cf39b13)

753.	[func]		muks
	libdns++: the unknown/generic (RFC 3597) RDATA class now uses the
	generic lexer in constructors from text.
	(Trac #2426, git 0770d2df84e5608371db3a47e0456eb2a340b5f4)

752.	[func]		tmark
	If configured to do so, b10-dhcp4 will now create DHCP-DDNS update
	requests and send them to b10-dhcp-ddns for processing.
	(Trac# 3329, git 4546dd186782eec5cfcb4ddb61b0a3aa5c700751)

751.	[func]		muks
	The BIND 10 zone loader now supports the $GENERATE directive (a
	BIND 9 extension).
	(Trac #2430, git b05064f681231fe7f8571253c5786f4ff0f2ca03)

750.	[func]		tomek
	b10-dhcp4, b10-dhcp6: Simple client classification has been
	implemented. Incoming packets can be assigned to zero or more
	client classes. It is possible to restrict subnet usage to a given
	client class. User's Guide and Developer's Guide has been updated.
	(Trac #3274, git 1791d19899b92a6ee411199f664bdfc690ec08b2)

749.	[bug]		tmark
	b10-dhcp-ddns now sets the TTL value in RRs that add A, AAAA, or PTR DNS
	entries to the lease length provided in instigating NameChangeRequest.
	This corrected a bug in which the TTL was always set to 0.
	(Trac# 3299, git dbacf27ece77f3d857da793341c6bd31ef1ea239)

748.	[bug]		marcin
	b10-dhcp4 server picks a subnet, to assign address for a directly
	connected client, using IP address of the interface on which the
	client's message has been received. If the message is received on
	the interface for which there is no suitable subnet, the message
	is discarded. Also, the subnet for renewing client which unicasts
	its request, is selected using ciaddr.
	(Trac #3242, git 9e571cc217d6b1a2fd6fdae1565fcc6fde6d08b1)

747.	[bug]		marcin
	libdhcpsrv: server configuration mechanism allows creating definitions
	for standard options for which Kea doesn't provide a definition yet.
	Without this, the server administrator couldn't configure options for
	which a definition didn't exist.
	(Trac# 3309, git 16a6ed6e48a6a950670c4874a2e81b1faf287d99)

746.	[func]		tomek
	IOAddress no longer exposes underlying asio objects. The getAddress()
	method has been removed and replaced with several convenience methods.
	(Trac #1485, git ecdb62db16b3f3d447db4a9d2a4079d5260431f0)

745.	[bug]		muks
	b10-auth now returns rcode=REFUSED for all questions with
	qtype=RRSIG (i.e., where RRSIGs are queried directly). This is
	because RRSIGs are meaningless without being bundled alongside the
	RRs they cover.
	(Trac #2226, git 68d24e65c9c3dfee38adfbe1c93367b0083f9a58)

744.	[func]		marcin
	b10-dhcp6: Refactored the code which is processing Client FQDN option.
	The major user-visible change is that server generates DDNS
	NameChangeRequest for the first IPv6 address (instead of all)
	acquired by a client. Also, the server generates fully qualified domain
	name from acquired IPv6 address, if the client sends an empty name in
	Client FQDN option.
	(Trac# 3295, git aa1c94a54114e848c64771fde308fc9ac0c00fd0)

743.	[func]		tmark
	b10-dhcp4 now responds with changes in DDNS behavior based upon
	configuration parameters specified through its dhcp-ddns configuration
	element. The parameters now supported are override-no-update,
	override-client-update, replace-client-name, generated-prefix, and
	qualifying-suffix.
	(Trac# 3282, git 42b1f1e4c4f5aa48b7588233402876f5012c043c)

742.	[func]		muks
	The authoritative server now includes the datasource configuration
	when logging some errors with the
	AUTH_DATASRC_CLIENTS_BUILDER_RECONFIGURE_ERROR message ID.
	(Trac #2756, git 31872754f36c840b4ec0b412a86afe9f38be86e0)

741.	[bug]		shane
	Remove hard-coded (and unnecessary) TSIG key from error message.
	This also prevents a crash if the TSIG name is missing.
	(Trac #3099, git 0ba8bbabe09756a4627e80aacdbb5050407faaac)

740.	[func]		muks
	When displaying messages about mismatched configuration data types
	in entered values (between the supplied value type and expected
	schema type), bindctl now includes both the supplied and expected
	configuration data types in the returned error. The user has more
	information on what caused the error now.
	(Trac #3239, git 84d5eda2a6ae0d737aef68d56023fc33fef623e6)

739.	[bug]		muks
	Various minor updates were made to the SSHFP RDATA parser. Mainly,
	the SSHFP constructor no longer throws an isc::BadValue exception.
	generic::SSHFP::getFingerprintLen() was also renamed to
	getFingerprintLength().
	(Trac #3287, git 2f26d781704618c6007ba896ad3d9e0c107d04b0)

738.	[bug]		muks
	b10-auth now correctly processes NXDOMAIN results in the root zone
	when using a SQLite3 data source.
	(Trac #2951, git 13685cc4580660eaf5b041b683a2d2f31fd24de3)

737.	[func]		muks
	b10-auth now additionally logs the source address and port when
	DNS messages with unsupported opcodes are received.
	(Trac #1516, git 71611831f6d1aaaea09143d4837eddbd1d67fbf4)

736.    [bug]           wlodek
	b10-dhcp6 is now capable to determine if a received
	message is addressed to it, using server identifier option.
	The messages with non-matching server identifier are dropped.
	(Trac #2892, git 3bd69e9b4ab9be231f7c966fd62b95a4e1595901)

735.	[doc]		stephen
	Expanded Developer's Guide to include chapter on logging.
	(Trac #2566, git a08d702839d9df6cddefeccab1e7e657377145de)

734.	[bug]		marcin
	libdhcp++: fixed a bug which caused an error when setting boolean
	values for an option. Also, bind10-guide has been updated with the
	examples how to set the boolean values for an option.
	(Trac# 3292, git 7c4c0514ede3cffc52d8c2874cdbdb74ced5f4ac)

733.	[bug]		marcin
	libdhcp++: a function which opens IPv6/UDPv6 sockets for the
	DHCPv6 server, gracefully handles errors to bind socket to
	a multicast address.
	(Trac #3288, git 76ace0c46a5fe0e53a29dad093b817ad6c891f1b)

732.	[func]		tomek
	b10-dhcp4, b10-dhcp6: Support for simplified client classification
        added. Incoming packets are now assigned to a client class based on
	the content of the packet's user class option (DHCPv4) or vendor class
	option (DHCPv6). Two classes (docsis3.0 and eRouter1.0) have class
	specific behavior in b10-dhcp4. See DHCPv4 Client Classification and
	DHCPv6 Client Classification in BIND10 Developer's Guide for details.
	This is a first ticket in a series of planned at least three tickets.
	(Trac #3203, git afea612c23143f81a4201e39ba793bc837c5c9f1)

731.	[func]		tmark
	b10-dhcp4 now parses parameters which support DHCP-DDNS updates via
	the DHCP-DDNS module, b10-dhcp-ddns.  These parameters are part of new
	configuration element, dhcp-ddns, defined in dhcp4.spec. The parameters
	parse, store and retrieve but do not yet govern behavior.  That will be
	provided under separate ticket.
	(Trac# 3033, git 0ba859834503f2b9b908cd7bc572e0286ca9201f)

730.	[bug]		tomek
	b10-dhcp4, b10-dhcp6: Both servers used to unnecessarily increase
	subnet-id values after reconfiguration. The subnet-ids are now reset
	to 1 every time a server is reconfigured.
	(Trac #3234, git 31e416087685a6dadc3047fdbb0927bbf60095aa)

729.	[bug]		marcin
	b10-dhcp4 discards DHCPv4 messages carrying server identifiers
	which don't match server identifiers used by the server.
	(Trac #3279, git 805d2b269c6bf3e7be68c13f1da1709d8150a666)

728.	[func]		marcin
	b10-dhcp6: If server fails to open a socket on one interface it
	will log a warning and continue to open sockets on other interfaces.
	The warning message is communicated from the libdhcp++ via the
	error handler function supplied by the DHCPv6 server.
	(Trac #3252, git af5eada1bba906697ee92df3fcc25cc0e3979221)

727.	[func]		muks
	RRset::setName() has now been removed.
	(Trac #2335, git c918027a387da8514acf7e125fd52c8378113662)

726.	[bug]		muks
	Don't print trailing newlines in Question::toText() output by
	default.  This fixes some logging that were split with a line
	feed.  It is possible to get the old behavior by passing
	toText(true).  Message::toText() output is unchanged.
	(Trac #571, git 7286499d5206c6d2aa8a59a5247c3841a772a43e)

725.	[func]		tmark
	b10-dhcp-ddns D2UpdateMgr now uses the newly implemented
	NameAddTransaction and NameRemoveTransaction classes.  This allows
	it to conduct actual DNS update exchanges based upon queued
	NameChangeRequests.
	(Trac# 3089, git 9ff948a169e1c1f3ad9e1bad1568375590a3ef42)

724.	[bug]		marcin
	b10-dhcp4: Different server identifiers are used for the packets
	being sent through different interfaces. The server uses IPv4 address
	assigned to the particular interface as a server identifier. This
	guarantees that the unicast packet sent by a relay or a client, to
	the address being a server identifier, will reach the server.
	(Trac #3231, git c7a229f15089670d2bfde6e9f0530c30ce6f8cf8)

723.	[bug]		marcin
	libdhcp++: Implemented unit tests for the IfaceMgr's routine
	which opens IPv6 sockets on detected interfaces. The IfaceMgr
	logic performing low level operations on sockets has been
	moved to a separate class. By providing a custom implementation
	of this class, the unit tests may use fake interfaces with
	custom configuration and thus cover wide range of test
	scenarios for the function.
	(Trac #3251, git 21d2f7ec425f8461b545687104cd76a42da61b2e)

722.	[bug]		muks
	b10-cmdctl now prints a more operator-friendly message when the
	address+port that b10-cmdctl listens on is already in use.
	(Trac #3227, git 5ec35e37dbb46f66ff0f6a9d9a6a87a393b37934)

721.	[func]		tmark
	Updates the user_chk example hooks shared library with callouts
	for packet receive and packet send.  Decision outcome now includes
	the lease or prefix assigned.  The user registry now supports a
	default user entry.
	(Trac #3207, git 34fddf2e75b80d9e517a8f9c3321aa4878cda795)

720.	[func]		tmark
	Added the initial implementation of the class, NameAddTransaction,
	to b10-dhcp-ddns.  This class provides a state machine which
	implements the logic required to remove forward and reverse DNS
	entries as described in RFC 4703, section 5.5. This includes the
	ability to construct the necessary DNS requests.
	(Trac# 3088, git ca58ac00fce4cb5f46e534d7ffadb2db4e4ffaf3)

719.	[func]		tomek
	b10-dhcp4: Support for sending back client-id (RFC6842) has been
	added now. Also a configuration parameter (echo-client-id) has
	been added, so it is possible to enable backward compatibility
	("echo-client-id false").
	(Trac #3210, git 88a4858db206dfcd53a227562198f308f7779a72)

718.	[func]		dclink, tomek
	libdhcp++: Interface detection implemented for FreeBSD, NetBSD,
	OpenBSD, Mac OS X and Solaris 11. Thanks to David Carlier for
	contributing a patch.
	(Trac #2246, git d8045b5e1580a1d0b89a232fd61c10d25a95e769)

717.	[bug]		marcin
	Fixed the bug which incorrectly treated DHCPv4 option codes 224-254 as
	standard options, barring them from being used as custom options.
	(Trac #2772, git c6158690c389d75686545459618ae0bf16f2cdb8)

716.	[func]		marcin
	perfdhcp: added support for sending DHCPv6 Release messages
	at the specified rate and measure performance. The orphan
	messages counters are not displayed for individual exchanges
	anymore. The following ticket: #3261 has been submitted to
	implement global orphan counting for all exchange types.
	(Trac #3181, git 684524bc130080e4fa31b65edfd14d58eec37e50)

715.	[bug]		marcin
	libdhcp++: Used the CMSG_SPACE instead of CMSG_LEN macro to calculate
	msg_controllen field of the DHCPv6 message. Use of CMSG_LEN causes
	sendmsg failures on OpenBSD due to the bug kernel/6080 on OpenBSD.
	(Trac #1824, git 39c9499d001a98c8d2f5792563c28a5eb2cc5fcb)

714.	[doc]		tomek
	BIND10 Contributor's Guide added.
	(Trac #3109, git 016bfae00460b4f88adbfd07ed26759eb294ef10)

713.	[func]		tmark
	Added DNS update request construction to d2::NameAddTransaction
	in b10-dhcp-ddns.  The class now generates all DNS update
	request variations needed to fulfill it's state machine in
	compliance with RFC 4703, sections 5.3 and 5.4.
	(Trac# 3241, git dceca9554cb9410dd8d12371b68198b797cb6cfb)

	b10-dhcp4: If server fails to open a socket on one interface it
	will log a warning and continue to open sockets on other interfaces.
	The warning message is communicated from the libdhcp++ via the

711.	[func]		tmark
	Added the initial implementation of the class, NameAddTransaction,
	to b10-dhcp-ddns.  This class provides the state model logic
	described in the DHCP_DDNS design to add or replace forward and
	reverse DNS entries for a given FQDN.  It does not yet construct
	the actual DNS update requests, this will be added under Trac#
	3241.
	(Trac# 3087, git 8f99da735a9f39d514c40d0a295f751dc8edfbcd)

710.	[build]		jinmei
	Fixed various build time issues for MacOS X 10.9.  Those include
	some general fixes and improvements:
	- (libdns++) masterLoad() functions now use the generic MasterLoader
	  class as backend, eliminating the restrictions of the previous
	  versions.
	- (libcc) fixed a minor portability bug in the JSON parser.  Although
	  the only known affected system is OS X 10.9 at the moment, that
	  could potentially cause disruption on other existing and future
	  systems.
	Other notes:
	- if built with googletest, gtest 1.7 (and possibly higher) is
	  required.
	- many older versions of Boost don't work.  A known workable version
	  is 1.54.

	b10-dhcp4: Server processes the DHCPv4 Client FQDN and Host Name
	options sent by a client and generates the response. As a result
	of processing, the server generates NameChangeRequests which
	represent changes to DNS mappings for a particular lease (addition
	or removal of DNS mappings).
	Currently all generated NameChangeRequests are dropped. Sending
	them to b10-dhcp-ddns will be implemented with the future tickets.

	b10-xfrin now has tighter control on the choice of IXFR or AXFR
	through zones/request_ixfr configuration item.  It includes
	the new "IXFR only" behavior for some special cases.  b10-xfrin
	now also uses AXFR whenever necessary, so it is now safe to try
	IXFR by default and it's made the default.  The previous
	use_ixfr configuration item was deprecated and triggers startup
	failure if specified; configuration using use_ixfr should be
	updated.

	that the existing string constructors for these Rdata classes also
	use the generic lexer, and they now expect an absolute name (with
	the trailing '.') in the name fields.

	b10-dhcp4: Added the ability for the server to respond to a
	directly connected client which does not yet have an IP address.
	On Linux, the server will unicast the response to the client's
	hardware address and the 'yiaddr' (the client's new IP
	address). Sending a response to the unicast address prevents other
	(not interested) hosts from receiving the server response. This
	capability is not yet implemented on non-Linux Operating Systems
	where, in all cases, the server responds to the broadcast
	address. The logic conforms to section 4.1 of RFC 2131.

	b10-cmdctl: fixed a hangup problem on receiving the shutdown
	command from bindctl.  Note, however, that cmdctl is defined as

	Worked around some unit test regressions on FreeBSD 9.1 due to
	a binary compatibility issue between standard and system
	libraries (http://www.freebsd.org/cgi/query-pr.cgi?pr=175453).
	While not all tests still pass, main BIND 10 programs should
	generally work correctly.  Still, there can be odd run time
	behavior such as abrupt crash instead of graceful shutdown
	when some fatal event happens, so it's generally discouraged to
	use BIND 10 on FreeBSD 9.1 RELEASE.  According to the above
	bug report for FreeBSD, it seems upgrading or downgrading the
	FreeBSD version will solve this problem.

	The "delete record" interface of the database based data source
	was extended so that the parameter includes reversed name in
	addition to the actual name.  This may help the underlying
	accessor implementation if reversed names are more convenient
	for the delete operation.  This was the case for the SQLite3
	accessor implementation, and it now performs delete operations
	much faster.  At a higher level, this means IXFR and DDNS Updates
	to the sqlite3 database are no longer so slow on large zones as
	they were before.

	The separate "static" data source is now deprecated as it can be

	This means existing configuration may not work after an update.
	If "config show data_sources/classes/CH[0]" on bindctl contains a
	"static" type of data source, you'll need to update it as follows:
	> config set data_sources/classes/CH[0]/type MasterFiles
	> config set data_sources/classes/CH[0]/params {"BIND": =>
	  "<the value of current data_sources/classes/CH[0]/params>"}
