ChangeLog

7XX.	[doc]		tomek
	Developer's Guide updated with pointers updated from BIND10 to
	Kea.
	(Trac #3396, git tbd)

791.	[func]		tmark
	DHCP-DDNS: Now supports configure.ac parameter: --with-kea-config.
	It allows selecting configuration backend and accepts one of two
	values: BUNDY, which uses Bundy (former BIND10) framework as Kea
	0.8 did, or JSON, which reads configuration from a JSON file.
	(Trac #3401, git 8e69209caafc81041229f3d9601599f3d98fc86e)

790.	[func]		marcin
	DHCPv4 server: 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 #3405, git dd0270bd91cf8fc958b8b388950d343d311ee99e)

789.	[bug]		marcin
	DHCPv4 server sends Renewal Time (58) and Rebinding Time (59)
	options to the client when the appropriate timers are set
	in the configuration. Previously, the timers were ignored.
	(Trac #3336, git b3c8a079889411182ade517c85aa4fe5d6b8719a)

788.	[func]		tomek
	DHCPv4 server: New parameter added to configure.ac: --with-kea-config.
	It allows selecting configuration backend and accepts one of two
	values: BUNDY, which uses Bundy (former BIND10) framework as Kea
	0.8 did, or JSON, which reads configuration from a JSON file.
	(Trac #3399, git 6e4dd3ae58c091ba0fd64c87fa8d7c268210f99b)

787.	[func]		marcin
	DHCPv6 server: 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 #3406, git 3be60fa6ac521aecae6ae92d26dc03792bc76903)

786.	[func]		tmark
	DHCP-DDNS now supports DDNS updates with TSIG.  Please refer to the
	Kea Guide for details. Prior to this TSIG keys could be defined but
	were not used.
	(Trac #3432, git 80fea12a53d1e832d4e7b710ca6ea613300f73ea)

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.
	(Trac #3246, git 50de7df4195195e981ae9c8c6f1b4100047d5bb5)

784.	[func]		tmark
	DHCP_DDNS's configuration was changed. The unused parameter, "interface"
	was deleted.  Three new parameters, "ncr_protocol", "ncr_format", and
	"dns_server_timeout" were added.  Please refer to Kea Guide for
	details.
	(Trac #3268,    git bd60252e679f19b062f61926647f661ab169f21c)

783.	[func]*		tomek
	DHCPv6 server: New parameter added to configure: --with-kea-config.
	It allows selecting configuration backend and accepts one of two
	values: BUNDY, which uses Bundy (former BIND10 framework as Kea
	0.8 did, or JSON, which reads configuration from a JSON file.
	(Trac #3400, git 7e9fdfa644b81f72bfa5300b7ddcdb9754400769)

782.	[func]		tmark
	Added sender-ip, sender-port, and max-queue-size parameters to
	the dhcp-ddns configuration section of both b10-dhcp4 and b10-dhcp6.
	(Trac #3328,    git 8d8d0b5eedaab20bf1008dfb3a6913eb006a6e73)

781.	[func]		marcin
	libkea-dhcpsrv: the Memfile lease storage backend returns leases
	of a specified type. Previously, it ignored the lease type parameter
	and returned all leases for a particular client. Thanks to David
	Carlier for helping to implement this ticket.
	(Trac #3148, git d2f0edf473716cd747a21d6917e89ba55c148d8e)

780.	[func]		marcin
	libkea-cc: JSON parser stores information about the position
	of the data element values in the JSON string. The position
	comprises the line number and the offset within this line where
	the specific value resides. This functionality is intended to
	be used for error logging during configuration parsing.
	(Trac #3408, git 115a52a6713340fc589f6f95d73d242931239405)

779.	[doc]		tmark
	Added a section to the developer's guide for Kea's DHCP-DDNS
	component, D2.
	(Trac #3158,    git  7be263c7372b1401a8b4288742854f96b5bec0d6)

bind10-1.2.0rc1 released on April 8, 2014

778.	[func]*		marcin
	libdhcpsrv: the Memfile lease storage backend now writes
	leases into a CSV file. Configuration parsers for b10-dhcp4
	and b10-dhcp6 use the new configuration parameters to
	control the location of the lease file. It is possible to
	disable lease writes to disk using configuration for testing
	purposes.
	(Trac #3360, git 09e6e71abf8bc693e389ebd262fd149b43c1f1d4)

777.	[func]		tmark
	If b10-dhcp-ddns is configured to listen on an address other than
	loopback, it will issue a log message warning the user that this is
	insecure and is supported for testing purposes only.
	(Trac #3383,    git  652aa4de2fa82fdf3de569d01d9f4aa618fc1972)

776.	[func]		tomek
	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
	switch the PostgreSQL backend is not compiled leaving BIND 10 able to
	be built on systems without PostgreSQL installed.  Thanks to David
	Carlier who contributed the initial patches for this work.
	(Trac #3080,    git  1aae8b1fab3008e62c4f085948b1abadad512447)

775.	[func]		marcin
	b10-dhcp4, b10-dhcp6: added a new parameter to subnet configuration.
	This parameter allows subnet ids to be set to arbitrary values or
	automatically generated values. Generated subnet ids are renumbered
	each time one or more subnets are removed.  Setting the ids to
	specific values prevents this renumbering.
	(Trac #3281, git d90e9a0642fbb16a4e664160b4812f61fb81f1aa)

774.	[doc]		marcin
	Updated information in the BIND 10 Guide about the standards supported
	by Kea and its current limitations.
	(Trac #3258, git ff52b86206e3a256a02ca6d5cde55040550ba86a)

773.	[doc]		tmark
	Added sections to the BIND 10 guide on configuring and using the
	DHCP-DDNS feature of Kea.  Chapter 19, describes the new DHCP-DDNS
	server and its configuration. Additions to chapters 17 and 18
	describe configuring the DHCP servers to work with the new server.
	(Trac #3283, git 806eea955c61eba2d7268958a740a8e8ea63bdaf)

772.	[bug]		tmark
	b10-dhcp4 and b10-dhcp6 now both correctly support DDNS updates
	when honoring client requested delegation. When DDNS is enabled,
	and the client's FQDN indicates they will do the forward updates,
	the servers will now post a DDNS update request to b10-dhcp-ddns
	for the reverse updates. Prior to this the servers were posting no
	DDNS update requests when honoring client delegation.
	(Trac #3352, git b1a0f405463723d539b2e6ed2dcdd692d7796b88)

771.	[bug]		tmark
	Ticket #3339 (entry 760) was reverted to fix regression
	where components added through bindctl, could not be removed.
	(Trac #3374, git c641e2d0569df3ca3e5a93beaf0ecf39db07e402)

770.	[bug]		tmark
	Configuration parsing in b10-dhcp6 and b10-dhcp4 for the "dhcp-ddns"
	section of their configurations now supplies hard-coded default values
	rather than those from their spec files.  This is a temporary solution
	to circumvent an issue in the configuration libraries which causes
	map-items to behave incorrectly.
	(Trac #3358, git 983d8acec3a7ccb1ffef662eac7518aed5f99381)

769.	[func]		marcin
	b10-dhcp6: Implemented support for Rebind message.
	(Trac #3232, git 3649413932857470558a6f19e0b0e181b3fc0fda)

768.	[bug]		tmark
	b10-dhcp-ddns now treats a DNS server response code of
	NXRRSET as a successful outcome when processing a request
	to remove DNS data.  This corrects a defect in which
	b10-dhcp-ddns would incorrectly fail a request to remove
	DNS data when the DNS server's response was NXRRSET.
	(Trac #3362, git da3b0d4f364d069ffdb47723545798ac589fae42)

767.	[func]		tomek
	Unit-tests for all DHCP database backends are now shared.
	This improves test coverage for memfile and any future
	backends that may appear.
	(Trac #3359, git 3d6c11630ada9d0681a813cf026f6bb16aabb9fa)

bind10-1.2.0beta1 released on March 6, 2014

766.	[func]		muks
	--disable-dns and --disable-dhcp configure arguments have been
	added to conditionally disable the DNS or DHCP components
	respectively. This facility can be used to do a DNS or DHCP-only
	build of BIND 10. DNS and DHCP components are both enabled by
	default.
	(Trac #2367, git 81a689b61b1c4abf8a1a4fcbe41cfc96fd11792a)

765.	[bug]		tomek
	b10-dhcp4: Fixed a minor bug in eRouter1.0 class processing. The
	server no longer sets giaddr field.
	(Trac #3353, git 23c22e9b1141c699f361d45c309e737dfecf6f3f)

764.	[bug]		tomek
	b10-dhcp4: Fixed a bug caused client classification to not work
	properly.
	(Trac #3343, git 1801400ac874380e7a565d373b4bae96a49e21f7)

763.	[func]		tmark
	b10-dhcp-ddns may now be configured to disable DNS updates in
	in a given direction by simply not defining any domains for that
	direction in its configuration.  This allows it to be configured to
	support either forward DNS or reverse DNS only.  Prior to this if
	a request was received that could not be matched to servers in a
	given direction it was failed immediately.
	(Trac #3341, git 01f26bce1d9faaddb8be59802f73891ea065b200)

762.	[func]		tmark
	If configured to do so, b10-dhcp6 will now create DHCP-DDNS update
	requests and send them to b10-dhcp-ddns for processing.
	(Trac# 3329, git 239956696465a13196a2b6bc0f3a61aed21a5de8)

761.	[doc]		stephen, jreed
	Added "man" page for perfdhcp.
	(Trac #2307, git ff2f538912c205fbdb1408ee613c09b90de53514)

760.	[bug]		tmark
	When merging a map of configuration elements into another, elements
	that are themselves maps will be merged. In particular, this
	corrects a defect which caused a configuration commit error to
	occur when using bindctl to modify a single a parameter in
	dhcp-ddns portion of b10-dhcp4 configuration.
	(Trac# 3339, git 3ae0d93d89f3277a566eeb045191a43b2dd9d9b1)

759.	[func]		tomek
	b10-dhcp4, b10-dhcp6: IP address of the relay agent can now be
	specified for both IPv4 and IPv6 subnets. That information allows
	the server to properly handle a case where relay agent address
	does not match subnet.  This is mostly useful in shared subnets
	and cable networks.
	(Trac #3322, git 5de565baea42c9096dff78ed5fbd05982a174469)

758.	[bug]		tmark
	b10-dhcp4 now correctly handles DHO_HOST_OPTION.  This corrects
	a bug where the server would fail to recognize the option in the
	DHCP request and then skip generating the appropriate DHCP-DDNS
	update request.
	(Trac #2426, git 985d66cba7665a71e17ef70c5d22c767abaad1b6)

757.	[func]		tmark
	b10-dhcp6 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. These parameters influence when and how DDNS updates
	requests are created but communicating them to b10-dhcp-ddns is
	not yet supported.  That will be provided under separate ticket,
	Trac #3222.
	(Trac# 3034, git 22c667a66536ff3e3741bc67025d824644ed4e7d)

756.	[bug]		marcin
	b10-dhcp6: server parses DHCPv6 Vendor Class option. Previously
	the server failed to parse Vendor Class option having empty opaque
	data field because of the invalid definition in libdhcp++. The
	DHCPv6 Vendor Class option and DHCPv4 V-I Vendor Class option is
	now represented by the new OptionVendorClass. The b10-dhcp4 is
	affected by this change such that it uses new class to parse the
	DHCPv4 V-I Vendor Class option.
	(Trac #3316, git 1e61d7db5b8dc76682aa568cd62bfae0eeff46e3)

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)

	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)

	While not all tests still pass, main BIND 10 programs should

	behavior such as abrupt crash instead of graceful shutdown
	when some fatal event happens, so it's generally discouraged to

	IP version (-4 or -6) does not match the command line argument
	given for the server. Prior to this perfdhcp would core when given
	an IP version of -6 but a valid IPv4 address for server.

	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.

	Changed mysql_lease_mgr to set the SQL mode option to STRICT. This
	causes mysql it to treat invalid input data as an error. Rather than
	"successfully" inserting a too large value by truncating it, the
	insert will fail, and the lease manager will throw an exception.
	Also, attempts to create a HWAddr (hardware address) object with
	too long an array of data now throw an exception.

	The separate "static" data source is now deprecated as it can be
	served in the more generic "MasterFiles" type of data source.
	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>"}
	> config set data_sources/classes/CH[0]/cache-enable true
	> config commit
	(Same for CH[1], CH[2], IN[0], etc, if applicable, although it
	should be very unlikely in practice.  Also note: '=>' above
	indicates the next line is actually part of the command.  Do
	not type in this "arrow").

	b10-dhcp6: Added unit tests for handling requests when no
	IPv6 subnets are configured/defined. Testing these conditions
	was overlooked during implementation of Trac #2719.

	Added special handling for the case where b10-auth receives a
	NOTIFY message, but zonemgr isn't running. Previously this was
	logged as a communications problem at the ERROR level, resulting
	in increasing noise when zonemgr is intentionally stopped. Other
	than the log level there is no change in externally visible
	behavior.

	libdns++: the NSEC, DS, DLV, and AFSDB Rdata classes now use the
	generic lexer in constructors from text.  This means that the name
	fields in such RRs in a zone file can now be non-absolute (the
	origin name in that context will be used), e.g., when loaded by
	b10-loadzone.
