ChangeLog

6XX.	[doc]		stephen
	Added the "Hook's Maintenance Guide" to the BIND 10 developer
	documentation.
	(Trac# 3063, git ABCD)

656.	[func]		tomek
	Additional hooks (buffer6_receive, lease6_renew,
	lease6_release, buffer6_send) added to the DHCPv6 server.
	(Trac #2984, git 540dd0449121094a56f294c500c2ed811f6016b6)

655.	[func]		tmark
	Added D2UpdateMgr class to b10-dhcp-ddns. This class is the b10-dhcp-ddns
	task master, instantiating and supervising transactions that carry out the
	DNS updates needed to fulfill the requests (NameChangeRequests) received
	from b10-dhcp-ddns clients (e.g. DHCP servers).
	(Trac #3059 git d72675617d6b60e3eb6160305738771f015849ba)

654.	[bug]		stephen
	Always clear "skip" flag before calling any callouts on a hook.
	(Trac# 3050, git ff0b9b45869b1d9a4b99e785fbce421e184c2e93)

653.	[func]		tmark
	Added initial implementation of D2QueueMgr to
	b10-dhcp-ddns.  This class manages the receipt and
	queueing of requests received by b10-dhcp-ddns from
	its clients (e.g. DHCP servers)
	(Trac# 3052, git a970f6c5255e000c053a2dc47926cea7cec2761c)

652.	[doc]		stephen
	Added the "Hook Developer's Guide" to the BIND 10 developer
	documentation.
	(Trac# 2982, git 26a805c7e49a9ec85ee825f179cda41a2358f4c6)

651.	[bug]		muks
	A race condition when creating cmdctl certificates caused corruption
	of these certificates in rare cases. This has now been fixed.
	(Trac# 2962, git 09f557d871faef090ed444ebeee7f13e142184a0)

650.	[func]		muks
	The DomainTree rebalancing code has been updated to be more
	understandable. This ChangeLog entry is made just to make a note
	of this change. The change should not cause any observable
	difference whatsoever.
	(Trac# 2811, git 7c0bad1643af13dedf9356e9fb3a51264b7481de)

649.	[func]		muks
	The default b10-xfrout also_notify port has been changed from
	0 to 53.
	(Trac# 2925, git 8acbf043daf590a9f2ad003e715cd4ffb0b3f979)

648.	[func]		tmark
	Moved classes pertaining to sending and receiving
	NameChangeRequests from src/bin/d2 into their own library,
	libdhcp_ddns, in src/lib/dhcp_ddns.  This allows the
	classes to be shared between DHDCP-DDNS and its clients,
	such as the DHCP servers.
	(Trac# 3065, git 3d39bccaf3f0565152ef73ec3e2cd03e77572c56)

647.	[func]		tmark
	Added initial implementation of classes for sending
	and receiving NameChangeRequests between DHCP-DDNS
	and its clients such as DHCP. This includes both
	abstract classes and a derivation which traffics
	requests across UDP sockets.
	(Trac #3008, git b54530b4539cec4476986442e72c047dddba7b48)

646.	[func]		stephen
	Extended the hooks framework to add a "validate libraries" function.
	This will be used to check libraries specified during BIND 10
	configuration.
	(Trac #3054, git 0f845ed94f462dee85b67f056656b2a197878b04)

645.	[func]		tomek
	Added initial set of hooks (pkt4_receive, subnet4_select,
	lease4_select, pkt4_send) to the DHCPv6 server.
	(Trac #2994, git be65cfba939a6a7abd3c93931ce35c33d3e8247b)

644.	[func]		marcin
	b10-dhcp4, b10-dhcp6: Implemented selection of the interfaces
	that server listens on, using Configuration Manager. It is
	possible to specify interface names explicitly or use asterisk
	to specify that server should listen on all available interfaces.
	Sockets are reopened according to the new configuration as
	soon as it is committed.
	(Trac #1555, git f48a3bff3fbbd15584d788a264d5966154394f04)

643.	[bug]		muks
	When running some unittests as root that depended on insufficient
	file permissions, the tests used to fail because the root user
	could still access such files. Such tests are now skipped when
	they are run as the root user.
	(Trac #3056, git 92ebabdbcf6168666b03d7f7fbb31f899be39322)

642.	[func]		tomek
	Added initial set of hooks (pkt6_receive, subnet6_select,
	lease6_select, pkt6_send) to the DHCPv6 server.
	(Trac #2995, git d6de376f97313ba40fef989e4a437d184fdf70cc)

641.	[func]		stephen
	Added the hooks framework. This allows shared libraries of
	user-written functions to be loaded at run-time and the
	functions called during packet processing.
	(Trac #2980, git 82c997a72890a12af135ace5b9ee100e41c5534e)

640.	[func]		marcin
	b10-dhcp-ddns: Implemented DNSClient class which implements
	asynchronous DNS updates using UDP. The TCP and TSIG support
	will be	implemented at later time. Nevertheless, class API
	accomodates the use of TCP and TSIG.
	(Trac #2977, git 5a67a8982baa1fd6b796c063eeb13850c633702c)

639.	[bug]		muks
	Added workaround for build failure on Fedora 19 between GCC 4.8.x
	and boost versions less than 1.54. Fedora 19 currently ships
	boost-1.53.
	(Trac #3039, git 4ef6830ed357ceb859ebb3e5e821a064bd8797bb)

638.	[bug]*		naokikambe
	Per-zone statistics counters are distinguished by zone class,
	e.g. IN, CH, and HS. A class name is added onto a zone name in
	structure of per-zone statistics.
	(Trac #2884, git c0153581c3533ef045a92e68e0464aab00947cbb)

637.	[func]		tmark
	Added initial implementation of NameChangeRequest,
	which embodies DNS update requests sent to DHCP-DDNS
	by its clients.
	(trac3007 git f33bdd59c6a8c8ea883f11578b463277d01c2b70)

636.	[func]		tmark
	Added the initial implementation of configuration parsing for
	DCHP-DDNS.
	(Trac #2957, git c04fb71fa44c2a458aac57ae54eeb1711c017a49)

635.	[func]		marcin
	b10-dhcp-ddns: Implemented DNS Update message construction.
	(Trac #2796, git eac5e751473e238dee1ebf16491634a1fbea25e2)

634.	[bug]		muks
	When processing DDNS updates, we now check the zone more
	thoroughly with the received zone data updates to check if it is
	valid.  If the zone fails validation, we reply with SERVFAIL
	rcode. So, while previously we may have allowed more zone data
	cases without checking which resulted in invalid zones, such
	update requests are now rejected.
	(Trac #2759, git d8991bf8ed720a316f7506c1dd9db7de5c57ad4d)

633.	[func]		jinmei
	b10-memmgr: a new BIND 10 module that manages shared memory
	segments for DNS zone data.  At this point it's runnable but does
	nothing really meaningful for end users; it was added to the
	master branch for further development.
	(Trac #2854, git d05d7aa36d0f8f87b94dba114134b50ca37eabff)

632.	[bug]		marcin
	perfdhcp: Fixed a bug in whereby the application was sporadically
	crashing when timed out packets were garbage collected.
	(Trac #2979, git 6d42b333f446eccc9d0204bcc04df38fed0c31db)

631.	[bug]		muks
	Applied a patch by Tomas Hozza to fix a couple of compile errors
	on Fedora 19 development release.
	(Trac #3001, git 6e42b90971b377261c72d51c38bf4a8dc336664a)

630.	[bug]		muks
	If there is a problem loading the backend module for a type of
	data source, b10-auth would not serve any zones. This behaviour
	has been changed now so that it serves zones from all other usable
	data sources that were configured.
	(Trac #2947, git 9a3ddf1e2bfa2546bfcc7df6d9b11bfbdb5cf35f)

629.	[func]		stephen
	Added first part of the hooks framework.
	(Trac #2794, git d2b107586db7c2deaecba212c891d231d7e54a07)

628.	[func]		y-aharen
	b10-auth: A new statistics item 'qryrecursion' has been introduced.
	The counter is for the number of queries (OpCode=Query) with Recursion
	Desired (RD) bit on.
	(Trac #2796, git 3d291f42cdb186682983aa833a1a67cb9e6a8434)

627.	[func]		tmark
	Logger name for DHCP-DDNS has been changed from "d2_logger" to
	"dhcpddns".  In addition, its log messages now use two suffixes,
	DCTL_ for logs the emanate from the underlying base classes, and
	DHCP_DDNS_ for logs which emanate from DHCP-DDNS specific code
	(Trac #2978, git 5aec5fb20b0486574226f89bd877267cb9116921)

626.	[func]		tmark
	Created the initial implementation of DHCP-DDNS service
	controller class, D2Controller, and the abstract class from
	which it derives,DControllerBase. D2Controller manages the
	lifecycle and BIND10 integration of the DHCP-DDNS application
	process, D2Process. Also note, module name is now
	b10-dhcp-ddns.
	(Trac #2956, git a41cac582e46213c120b19928e4162535ba5fe76)

625.	[bug]*		jinmei
	b10-xfrin/b10-loadzone: b10-xfrin now refers to the unified
	"data_sources" module configuration instead of almost-deprecated
	the Auth/database_file configuration (Note: zonemgr still uses the
	latter, so a secondary server would still need it for the moment).
	Due to this change, b10-xfrin does not auto-generate an initial
	zone for the very first transfer anymore; b10-loadzone has been
	extended with a new -e option for the initial setup.
	(Trac #2946, git 8191aec04c5279c199909f00f0a0b2b8f7bede94)

624.	[bug]		jinmei
	logging: prevented multiple BIND 10 processes from generating
	multiple small log files when they dumped logs to files and try
	to roll over them simultaneously.  This fix relies on a feature of
	underling logging library (log4cplus) version 1.1.0 or higher,
	so the problem can still happen if BIND 10 is built with an older
	version of log4cplus. (But this is expected to happen rarely in
	any case unless a verbose debug level is specified).
	(Trac #1622, git 5da8f8131b1224c99603852e1574b2a1adace236)

623.	[func]		tmark
	Created the initial, bare-bones implementation of DHCP-DDNS service
	process class, D2Process, and the abstract class from which it derives,
	DProcessBase. D2Process will provide the DHCP-DDNS specific event loop
	and business logic.
	(Trac #2955, git dbe4772246039a1257b6492936fda2a8600cd245)

622.	[func]*		jinmei
	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.
	(Trac #2911, git 8118f8e4e9c0ad3e7b690bbce265a163e4f8767a)

621.	[func]		team
	libdns++: All 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. Note
	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.
	(Trac #2522, git ea97070cf6b41299351fc29af66fa39c6465d56a)
	(Trac #2521, git c6603decaadcd33ccf9aee4a7b22447acec4b7f6)
	(See also ChangeLog 594, 564, 545)

620.	[bug]		jinmei
	b10-auth now returns SERVFAIL to queries for a zone that is
	configured to be loaded in-memory but isn't due to load time
	errors (missing zone file or errors in the zone file, etc).
	Such zones were previously treated as non existent and would
	result in REFUSED or unintentional match against less specific
	zones.  The revised behavior is also compatible with BIND 9.
	(Trac #2905, git 56ee9810fdfb5f86bd6948e6bf26545ac714edd8)

619.	[bug]		jinmei
	b10-xfrout now uses blocking send for xfr response messages
	to prevent abrupt termination of the stream due to a slower
	client or narrower network bandwidth.
	(Trac #2934, git bde0e94518469557c8b455ccbecc079a38382afd)

618.	[func]*		marcin
	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.
	(Trac #2902, git c2d40e3d425f1e51647be6a717c4a97d7ca3c29c)

617.	[bug]		marcin
	b10-dhcp4: Fixed a bug whereby the domain-name option was encoded
	as FQDN (using technique described in RFC1035) instead of a string.
	Also, created new class which represents an option carrying a single
	string value. This class is now used for all standard options of
	this kind.
	(Trac #2786, git 96b1a7eb31b16bf9b270ad3d82873c0bd86a3530)

616.	[doc]		stephen
	Added description to the DHCP "Database Back-Ends" section of the
	BIND 10 Developer's Guide about how to set up a MySQL database for
	testing the DHCP MySQL backend.
	(Trac #2653, git da3579feea036aa2b7d094b1c260a80a69d2f9aa)

615.	[bug]		jinmei
	b10-auth: Avoid referencing to a freed object when authoritative
	server addresses are reconfigured.  It caused a crash on a busy
	server during initial startup time, and the same crash could also
	happen if listen_on parameters are reconfigured at run time.
	(Trac #2946, git d5f2a0d0954acd8bc33aabb220fab31652394fcd)

614.	[func]		tmark
	b10-d2: Initial DHCP-DDNS (a.k.a. D2) module implemented.
	Currently it does nothing useful, except for providing the
	skeleton implementation to be expanded in the future.
	(Trac #2954, git 392c5ec5d15cd8c809bc9c6096b9f2bfe7b8c66a)

613.	[func]		jinmei
	datasrc: Error handling in loading zones into memory is now more
	consistent and convenient: data source configuration does not fail
	due to zones configured to be loaded into memory but not available
	in the data source, just like the case of missing zone file for
	the MasterFiles type of data source.  Also, zones that aren't
	loaded into memory due to errors can now be reloaded for b10-auth
	using the bindctl Auth loadzone command after fixing the error,
	without reconfiguring the entire data source.
	(Trac #2851, git a3d4fe8a32003534150ed076ea0bbf80e1fcc43c)

612.	[func]		tomek
	b10-dhcp6: Support for relayed DHCPv6 traffic has been added.
	(Trac #2898, git c3f6b67fa16a07f7f7ede24dd85feaa7c157e1cb)

611.	[func]		naokikambe
	Added Xfrin statistics items such as the number of successful
	transfers.  These are per-zone type counters.  Their values can be
	obtained with zone names by invoking "Stats show Xfrin" via bindctl
	while Xfrin is running.
	(Trac #2252, git e1a0ea8ef5c51b9b25afa111fbfe9347afbe5413)

bind10-1.1.0beta2 released on May 10, 2013

610.	[bug]		muks
	When the sqlite3 program is not available on the system (in
	PATH), we no longer attempt to run some tests which depend
	on it.
	(Trac #1909, git f85b274b85b57a094d33ca06dfbe12ae67bb47df)

609.	[bug]		jinmei
	Handled some rare error cases in DNS server classes correctly.
	This fix specifically solves occasional crash of b10-auth due to
	errors caused by TCP DNS clients.  Also, as a result of cleanups
	with the fix, b10-auth should now be a little bit faster in
	handling UDP queries: in some local experiments it ran about 5%
	faster.
	(Trac #2903, git 6d3e0f4b36a754248f8a03a29e2c36aef644cdcc)

608.	[bug]		jinmei
	b10-cmdctl: fixed a hangup problem on receiving the shutdown
	command from bindctl.  Note, however, that cmdctl is defined as
	a "needed" module by default, so shutting down cmdctl would cause
	shutdown of the entire BIND 10 system anyway, and is therefore
	still not very useful in practice.
	(Trac #2712, git fa392e8eb391a17d30550d4b290c975710651d98)

607.	[bug]		jinmei
	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.
	(Trac #2887, git 69dfb4544d9ded3c10cffbbfd573ae05fdeb771f)

606.	[bug]		jinmei
	b10-xfrout now correctly stops sending notify requests once it
	receives a valid response.  It previously handled it as if the
	requests are timed out and resent it a few times in a short
	period.
	(Trac #2879, git 4c45f29f28ae766a9f7dc3142859f1d0000284e1)

605.	[bug]		tmark
	Modified perfdhcp to calculate the times displayed for packet sent
	and received as time elapsed since perfdhcp process start time.
	Previously these were times since the start of the epoch.
	However the large numbers involved caused loss of precision
	in the calculation of the test statistics.
	(Trac #2785, git e9556924dcd1cf285dc358c47d65ed7c413e02cf)

604.	[func]		marcin
	libdhcp++: abstracted methods which open sockets and send/receive
	DHCP4 packets to a separate class. Other classes will be derived
	from it to implement OS-specific methods of DHCPv4 packets filtering.
	The primary purpose for this change is to add support for Direct
	DHCPv4 response to a client which doesn't have an address yet on
	different OSes.
	(Trac #991, git 33ffc9a750cd3fb34158ef676aab6b05df0302e2)

	The directory in which the b10-dchp4 and b10-dhcp6 server id files has
	been changed from the local state directory (set by the "configure"
	--localstatedir switch) to the "bind10" subdirectory of it. After an
	upgrade, server id files in the former location will be orphaned and
	should be manually removed.
	(Trac #2770, git a622140d411b3f07a68a1451e19df36118a80650)

602.	[bug]		tmark
	Perfdhcp will now exit gracefully if the command line argument for
	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.
	(Trac #2784, git 96b66c0c79dccf9a0206a45916b9b23fe9b94f74)

601.	[bug]*		jinmei, vorner
	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.
	(Trac #2877, git 33bd949ac7288c61ed0a664b7329b50b36d180e5)

600.	[bug]		tmark
	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.

bind10-1.1.0beta1 released on April 4, 2013

598.	[func]*		jinmei
	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>"}

	b10-loadzone was fully overhauled.  It now uses C++-based zone
	parser and loader library, performing stricter checks, having
	more complete support for master file formats, producing more
	helpful logs, is more extendable for various types of data
	sources, and yet much faster than the old version.  In
	functionality the new version should be generally backwards
	compatible to the old version, but there are some
	incompatibilities: name fields of RDATA (in NS, SOA, etc) must
	be absolute for now; due to the stricter checks some input that was
	(incorrectly) accepted by the old version may now be rejected;
	command line options and arguments are not compatible.

	The in-memory data source now uses a more complete master

	it supports multi-line RR representation and more complete
	support for escaped and quoted strings.  It also produces
	more helpful log messages when there is an error in the zone
	file.  It will be enhanced as more specific tasks in the
	#2368 meta ticket are completed.  The new parser is generally
	backward compatible to the previous one, but due to the
	tighter checks some input that has been accepted so far
	could now be rejected, so it's advisable to check if you
	use textual zone files directly loaded to memory.

	then dropped the privilege, the bind10 process cannot kill the
	sockcreator via signal any more (when it has to), but it kept
	sending the signal and didn't stop.  Also, when running on Python
	3.1 (or older), the sockcreator had some additional file
	descriptor open, which prevented it from exiting even after the
	bind10 process terminated.  Now the bind10 process simply gives up
	killing a subprocess if it fails due to lack of permission, and it
	makes sure the socket creator is spawned without any unnecessary

	libdhcp++: Added new parameter to define sub-second timeout
	for DHCP packet reception. The total timeout is now specified
	by two parameters:  first specifies integral number of
	seconds, second (which defaults to 0) specifies fractional
	seconds with microsecond resolution.
	(Trac #2231, git 15560cac16e4c52129322e3cb1787e0f47cf7850)

482.	[func]		team
	Memory footprint of the in-memory data source has been
	substantially improved.  For example, b10-auth now requires much
	less memory than BIND 9 named for loading and serving the same
	zone in-memory.  This is a transparent change in terms of user
	operation; there's no need to update or change the configuration
	to enable this feature.
	Notes: multiple instances of b10-auth still make separate copies
	of the memory image.  Also, loading zones in memory still suspends
	query processing, so manual reloading or reloading after incoming
	transfer may cause service disruption for huge zones.
	(Multiple Trac tickets, Summarized in Trac #2101)

	The abbreviated form of IP addresses in ACLs is accepted
	(eg. "from": ["127.0.0.1", "::1"] now works).

	Refactored perfdhcp tool to C++, added missing unit tests and removed
	the old code. The new code uses libdhcp++ (src/lib/dhcp) for DHCP
	packet management, network interface management and packet
	transmission.

	New statistics items added into b10-xfrout: ixfr_running and
	axfr_running.  Their values can be obtained by invoking "Stats show
	Xfrout" via bindctl while b10-xfrout is running.

475.	[func]		naokikambe
	Added Xfrout statistics counters: notifyoutv4, notifyoutv6,
	xfrrej, and xfrreqdone. These are per-zone type counters.
	The value of these counters can be seen with zone name by
	invoking "Stats show Xfrout" via bindctl.

	All generated documentation is removed from the git repository.
	The ./configure --enable-man option is removed. A new option

	built and installed if not used. Distributed tarballs will
	contain the generated documentation.

470.	[func]		naokikambe
	The stats module now supports partial statistics updates. Each
	module can return only statistics data which have been updated since
	the last time it sent them to the stats module. The purpose of partial
	updates is to reduce the amount of statistics data sent through the
	message queue.

	libdatasrc: the data source client list class now ignores zone
	content problems (such as out-of-zone data) in MasterFiles type
	zones, instead of aborting the entire configuration.  It only logs
	an error, and all other zones and datasources are still loaded. The
	error log message has been improved to include the zone origin and
	source file name.  As a result of this change, b10-auth no longer
	exits upon encountering such errors during startup.

	b10-stats polls the bind10 and b10-auth with new 'getstats' command
	to retrieve statistics data.  The "poll-interval" parameter in
	b10-stats is for configuring the polling interval.  All statistics
	data collected once are preserved while b10-stats is running.
	The "sendstats" command was removed from bind10 and b10-auth. The
	"statistics-interval" configuration item was removed from b10-auth.

	BIND 10 now relies on Boost offset_ptr, which caused some new
	portability issues.  Such issues are detected at ./configure time.
	If ./configure stops due to this, try the following workaround:
	- If it's about the use of mutable for a reference with clang++,
	  upgrade Boost version to 1.44 or higher, or try a different
	  compiler (e.g. g++ generally seems to be free from this issue)
	- If it's about the use of "variadic templates", specify
	  --without-werror so the warning won't be promoted to an error.
	  Specifying BOOST_NO_USER_CONFIG in CXXFLAGS may also work
	  (which would be the case if Boost is installed via pkgsrc)
