ChangeLog

502.    [func]      vorner
	TTLs can be specified with units as well as number of seconds now.
	This allows specifications like "1D3H".
	(Trac #2384, git 44c321c37e17347f33ced9d0868af0c891ff422b)

501.	[func]      tomek
	Added DHCPv6 allocation engine, now used in the processing of DHCPv6
	messages.
	(Trac #2414, git b3526430f02aa3dc3273612524d23137b8f1fe87)

500.	[bug]		jinmei
	Corrected the autoconf example in the examples directory so it can
	use the configured path to Boost to check availability of the BIND 10
	library.  Previously the sample configure script could fail if
	Boost is installed in an uncommon place.  Also, it now provides a
	helper m4 function and example usage for embedding the library
	path to executable (using linker options like -Wl,-R) to help
	minimize post-build hassles.
	(Trac #2356, git 36514ddc884c02a063e166d44319467ce6fb1d8f)

499.	[func]		team
	The b10-auth 'loadzone' command now uses the internal thread
	introduced in 495 to (re)load a zone in the background, so that
	query processing isn't blocked while loading a zone.
	(Trac #2213, git 686594e391c645279cc4a95e0e0020d1c01fba7e)

498.	[func]		marcin
	Implemented DHCPv6 option values configuration using configuration
	manager. In order to set values for data fields carried by the
	particular option, user specifies the string of hexadecimal digits
	that is in turn converted to binary data and stored into option buffer.
	More user friendly way of option content specification is planned.
	(Trac #2318, git e75c686cd9c14f4d6c2a242a0a0853314704fee9)

497.	[bug]		jinmei
	Fixed several issues in isc-sysinfo:
	- make sure it doesn't report a negative value for free memory
	  size (this happened on FreeBSD, but can possibly occur on other
	  BSD variants)
	- correctly identifies the SMP support in kernel on FreeBSD
	- print more human readable uptime as well as the time in seconds
	(Trac #2297, git 59a449f506948e2371ffa87dcd19059388bd1657)

496.	[func]		tomek
	DHCPv6 Allocation Engine implemented. It allows address allocation
	from the configured subnets/pools. It currently features a single
	allocator: IterativeAllocator, which assigns addresses iteratively.
	Other allocators (hashed, random) are planned.
	(Trac #2324, git 8aa188a10298e3a55b725db36502a99d2a8d638a)

495.	[func]		team
	b10-auth now handles reconfiguration of data sources in
	background using a separate thread.  This means even if the new
	configuration includes a large amount of data to be loaded into
	memory (very large zones and/or a very large number of zones),
	the reconfiguration doesn't block query handling.
	(Multiple Trac tickets up to #2211)

494.	[bug]		jinmei
	Fixed a problem that shutting down BIND 10 kept some of the
	processes alive.  It was two-fold: when the main bind10 process
	started as a root, started b10-sockcreator with the privilege, and
	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
	FDs open.
	(Trac #1858, git 405d85c8a0042ba807a3a123611ff383c4081ee1)

493.	[build]		jinmei
	Fixed build failure with newer versions of clang++.  These
	versions are stricter regarding "unused variable" and "unused
	(driver) arguments" warnings, and cause fatal build error
	with -Werror.  The affected versions of clang++ include Apple's
	customized version 4.1 included in Xcode 4.5.1.  So this fix
	will solve build errors for Mac OS X that uses newer versions of
	Xcode.
	(Trac #2340, git 55be177fc4f7537143ab6ef5a728bd44bdf9d783,
	3e2a372012e633d017a97029d13894e743199741 and commits before it
	with [2340] in the commit log)

492.	[func]		tomek
	libdhcpsrv: The DHCP Configuration Manager is now able to store
	information about IPv4 subnets and pools. It is still not possible
	to configure that information. Such capability will be implemented
	in a near future.
	(Trac #2237, git a78e560343b41f0f692c7903c938b2b2b24bf56b)

491.	[func]		tomek
	b10-dhcp6: Configuration for DHCPv6 has been implemented.
	Currently it is possible to configure IPv6 subnets and pools
	within those subnets, global and per subnet values of renew,
	rebind, preferred and valid lifetimes. Configured parameters
	are accepted, but are not used yet by the allocation engine yet.
	(Trac #2269, git 028bed9014b15facf1a29d3d4a822c9d14fc6411)

490.	[func]		tomek
	libdhcpsrv: An abstract API for lease database has been
	implemented. It offers a common interface to all concrete
	database backends.
	(Trac #2140, git df196f7609757253c4f2f918cd91012bb3af1163)

489.	[func]		muks
	The isc::dns::RRsetList class has been removed. It was now unused
	inside the BIND 10 codebase, and the interface was considered
	prone to misuse.
	(Trac #2266, git 532ac3d0054f6a11b91ee369964f3a84dabc6040)

488.	[build]		jinmei
	On configure, changed the search order for Python executable.
	It first tries more specific file names such as "python3.2" before
	more generic "python3".  This will prevent configure failure on
	Mac OS X that installs Python3 via recent versions of Homebrew.
	(Trac #2339, git 88db890d8d1c64de49be87f03c24a2021bcf63da)

487.	[bug]		jinmei
	The bind10 process now terminates a component (subprocess) by the
	"config remove Boss/components" bindctl command even if the
	process crashes immediately before the command is sent to bind10.
	Previously this led to an inconsistent state between the
	configuration and an internal component list of bind10, and bind10
	kept trying to restart the component.  A known specific case of
	this problem is that b10-ddns could keep failing (due to lack of
	dependency modules) and the administrator couldn't stop the
	restart via bindctl.
	(Trac #2244, git 7565788d06f216ab254008ffdfae16678bcd00e5)

486.	[bug]*		jinmei
	All public header files for libb10-dns++ are now installed.
	Template configure.ac and utility AC macros for external projects
	using the library are provided under the "examples" directory.
	The src/bin/host was moved as part of the examples (and not
	installed with other BIND 10 programs any more).
	(Trac #1870, git 4973e638d354d8b56dcadf71123ef23c15662021)

485.	[bug]		jelte
	Several bugs have been fixed in bindctl; tab-completion now works
	within configuration lists, the problem where sometimes the
	completion added a part twice has been solved, and it no longer
	suggests the confusing value 'argument' as a completion-hint for
	configuration items. Additionally, bindctl no longer crashes upon
	input like 'config remove Boss'.
	(Trac #2254, git 9047de5e8f973e12e536f7180738e6b515439448)

484.	[func]		tomek
	A new library (libb10-dhcpsrv) has been created. At present, it
	only holds the code for the DHCP Configuration Manager. Currently
	this object only supports basic configuration storage for the DHCPv6
	server,	but that capability will be expanded.
	(Trac #2238, git 6f29861b92742da34be9ae76968e82222b5bfd7d)

bind10-devel-20120927 released on September 27, 2012

483.	[func]		marcin
	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)

481.	[bug]		vorner
	The abbreviated form of IP addresses in ACLs is accepted
	(eg. "from": ["127.0.0.1", "::1"] now works).
	(Trac #2191, git 48b6e91386b46eed383126ad98dddfafc9f7e75e)

479.	[func]		marcin
	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.

478.	[func]		naokikambe
	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.
	(Trac #2222, git 91311bdbfea95f65c5e8bd8294ba08fac12405f1)

	Fixed a problem with b10-msgq on OSX when using a custom Python
	installation, that offers an unreliable select.poll() interface.
	(Trac #2190, git e0ffa11d49ab949ee5a4ffe7682b0e6906667baa)

476.	[bug]		vorner
	The Xfrin now accepts transfers with some TSIG signatures omitted, as
	allowed per RFC2845, section 4.4. This solves a compatibility
	issues with Knot and NSD.
	(Trac #1357, git 7ca65cb9ec528118f370142d7e7b792fcc31c9cf)

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.

	TCP connections now time out in b10-auth if no (or not all) query
	data is sent by the client. The timeout value defaults to 5000
	milliseconds, but is configurable in Auth/tcp_recv_timeout.
	(Trac #357, git cdf3f04442f8f131542bd1d4a2228a9d0bed12ff)

472.	[build]		jreed
	All generated documentation is removed from the git repository.
	The ./configure --enable-man option is removed. A new option
	-enable-generate-docs is added; it checks for required
	documentation building dependencies. Dummy documentation is
	built and installed if not used. Distributed tarballs will
	contain the generated documentation.

	Fixed a problem when b10-loadzone tried to tread semicolon
	in string data as start of comment, which caused invalid
	data being loaded.
	(Trac #2188, git 12efec3477feb62d7cbe36bdcfbfc7aa28a36f57)

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.
	(Trac #2179, git d659abdd9f3f369a29830831297f64484ac7b051)

469.	[bug]		jelte
	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.
	(Trac #2178, git a75ed413e8a1c8e3702beea4811a46a1bf519bbd)

468.	[func]*		naokikambe, fujiwara
	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)

	Created a new tool b10-dbutil, that can check and upgrade database
	schemas, to be used when incompatible changes are introduced in the
	backend database schema. Currently it only supports sqlite3 databases.
	Note: there's no schema change that requires this utility as of

412.	[func]		jelte
	Added a command-line option '--clear-config' to bind10, which causes
	the system to create a backup of the existing configuration database
	file, and start out with a clean default configuration. This can be

	b10-auth now also experimentally supports statistics counters of
	the rcode responses it sends. The counters can be shown as

	Configuration commands in bindctl now check for list indices if
	the 'identifier' argument points to a child element of a list
	item. Previously, it was possible to 'get' non-existent values
	by leaving out the index, e.g. "config show Auth/listen_on/port,
	which should be config show Auth/listen_on[<index>]/port, since
	Auth/listen_on is a list. The command without an index will now
	show an error. It is still possible to show/set the entire list
	("config show Auth/listen_on").

376.	[bug]		jinmei, vorner
	The new query handling module of b10-auth did not handle type DS
	query correctly: It didn't look for it in the parent zone, and
	it incorrectly returned a DS from the child zone if it
	happened to exist there.  Both were corrected, and it now also
	handles the case of having authority for the child and a grand
	ancestor.

	Modules now inform the system when they are stopping. As a result,
	they are removed from the 'active modules' list in bindctl, which
	can then inform the user directly when it tries to send them a

	in a 'not responding' error instead of 'not running'.

	libdatasrc: in-memory data source could incorrectly reject to load

	b10-auth experimentally supports statistics counters of incoming

	Added dummy DDNS module b10-ddns. Currently it does not
	provide any functionality, but it is a skeleton implementation
	that will be expanded later.

362.	[func]*		vorner
	Due to the socket creator changes, b10-auth and b10-resolver
	are no longer needed to start as root. They are started as
	the user they should be running, so they no longer have
	the -u flag for switching the user after initialization.
	Note: this change broke backward compatibility to boss component
	configuration.  If your b10-config.db contains "setuid" for
	Boss.components, you'll need to remove that entry by hand before
	starting BIND 10.

359.	[bug]		kevin
	Corrected SOA serial check in xfrout.  It now compares the SOA
	serial of an IXFR query with that of the server based serial
	number arithmetic, and replies with a single SOA record of the
	server's current version if the former is equal to or newer
	than the latter.

358.	[bug]		jinmei
	b10-resolver ignored default configuration parameters if listen_on
	failed (this can easily happen especially for a test environment
	where the run time user doesn't have root privilege), and even if
	listen_on was updated later the resolver wouldn't work correctly
	unless it's fully restarted (for example, all queries would be
	rejected due to an empty ACL).

357.	[bug]		jinmei
	ZoneFinder::find() for database based data sources didn't
	correctly identify out-of-zone query name and could return a
	confusing result such as NXRRSET.  It now returns NXDOMAIN with an
	empty RRset.  Note: we should rather throw an exception in such a
	case, which should be revisited later (see Trac #1536).

	Python xfrin.diff module incorrectly combined RRSIGs of different

	libdhcp++: Transmission and reception of DHCPv4 packets is now

	Alpha version of DHCP benchmarking tool added.  "perfdhcp" is able to
	test both IPv4 and IPv6 servers: it can time the four-packet exchange
	(DORA and SARR) as well as time the initial two-packet exchange (DO

	Fixed a bug where adding Zonemgr/secondary_zones without explicitly
	setting the class value of the added zone resulted in a cryptic
