ChangeLog

522.	[func]		jelte
	Configuration of TSIG keys for b10-xfrin has changed; instead of
	specifying the full TSIG key (<name>:<base64>:<algo>) it now expects
	just the name, and uses the global TSIG Key Ring like all the other
	components (configuration list /tsig_keys/keys).
	Note: this is not automatically updated, so if you use TSIG in
	xfrin, you need to update your configuration.
	(Trac #1351, git e65b7b36f60f14b7abe083da411e6934cdfbae7a)

521.	[func]		marcin
	Implemented definitions for DHCPv6 standard options identified
	by codes up to 48. These definitions are now used by the DHCPv6
	server to create instances of options being sent to a client.
	(Trac #2491, git 0a4faa07777189ed9c25211987a1a9b574015a95)

520.	[func]		jelte
	The system no longer prints initial log messages to stdout
	regardless of what logging configuration is present, but it
	temporarily stores any log messages until the configuration is
	processed. If there is no specific configuration, or if the
	configuration cannot be accessed, it will still fall back to stdout.
	Note that there are still a few instances where output is printed,
	these shall be addressed separately.
	Note also that, currently, in case it falls back to stdout (such as
	when it cannot connect to b10-cfgmgr), all log messages are always
	printed (including debug messages), regardless of whether -v was
	used. This shall also be addressed in a future change.
	(Trac #2445, git 74a0abe5a6d10b28e4a3e360e87b129c232dea68)

519.	[bug]		muks
	Fixed a problem in inmem NSEC lookup which caused returning an
	incorrect NSEC record or (in rare cases) assert failures
	when a non-existent domain was queried, which was a sub-domain of
	a domain that existed.
	(Trac #2504, git 835553eb309d100b062051f7ef18422d2e8e3ae4)

518.	[func]		stephen
	Extend DHCP MySQL backend to handle IPv4 addresses.
	(Trac #2404, git ce7db48d3ff5d5aad12b1da5e67ae60073cb2607)

517.	[func]		stephen
	Added IOAddress::toBytes() to get byte representation of address.
	Also added convenience methods for V4/V6 address determination.
	(Trac #2396, git c23f87e8ac3ea781b38d688f8f7b58539f85e35a)

516.	[bug]		marcin
	Fixed 'make distcheck' failure when running perfdhcp unit tests.
	The unit tests used to read files from the folder specified
	with the path relative to current folder, thus when the test was
	run from a different folder the files could not be found.
	(Trac #2479, git 4e8325e1b309f1d388a3055ec1e1df98c377f383)

515.	[bug]		jinmei
	The in-memory data source now accepts an RRSIG provided without
	a covered RRset in loading.  A subsequent query for its owner name
	of the covered type would generally result in NXRRSET; if the
	covered RRset is of type NSEC3, the corresponding NSEC3 processing
	would result in SERVFAIL.
	(Trac #2420, git 6744c100953f6def5500bcb4bfc330b9ffba0f5f)

514.	[bug]		jelte
	b10-msgq now handles socket errors more gracefully when sending data
	to clients. It no longer exits with 'broken pipe' errors, and is
	also better at resending data on temporary error codes from send().
	(Trac #2398, git 9f6b45ee210a253dca608848a58c824ff5e0d234)

513.	[func]		marcin
	Implemented the OptionCustom class for DHCPv4 and DHCPv6.
	This class represents an option which has a defined
	structure: a set of data fields of specific types and order.
	It is used to represent those options that can't be
	represented by any other specialized class.
	(Trac #2312, git 28d885b457dda970d9aecc5de018ec1120143a10)

512.	[func]		jelte
	Added a new tool b10-certgen, to check and update the self-signed
	SSL certificate used by b10-cmdctl. The original certificate
	provided has been removed, and a fresh one is generated upon first
	build. See the b10-certgen manpage for information on how to update
	existing installed certificates.
	(Trac #1044, git 510773dd9057ccf6caa8241e74a7a0b34ca971ab)

511.	[bug]		stephen
	Fixed a race condition in the DHCP tests whereby the test program
	spawned a subprocess and attempted to read (without waiting) from
	the interconnecting pipe before the subprocess had written
	anything.  The lack of output was being interpreted as a test
	failure.
	(Trac #2410, git f53e65cdceeb8e6da4723730e4ed0a17e4646579)

510.	[func]		marcin
	DHCP option instances can be created using a collection of strings.
	Each string represents a value of a particular data field within
	an option. The data field values, given as strings, are validated
	against the actual types of option fields specified in the options
	definitions.
	(Trac #2490, git 56cfd6612fcaeae9acec4a94e1e5f1a88142c44d)

509.	[func]		muks
	Log messages now include the pid of the process that logged the
	message.
	(Trac #1745, git fc8bbf3d438e8154e7c2bdd322145a7f7854dc6a)

508.	[bug]		stephen
	Split the DHCP library into two directories, each with its own
	Makefile.  This properly solves the problem whereby a "make"
	operation with multiple threads could fail because of the
	dependencies between two libraries in the same directory.
	(Trac #2475, git 834fa9e8f5097c6fd06845620f68547a97da8ff8)

bind10-devel-20121115 released on November 15, 2012

507.	[doc]		jelte
	Added a chapter about the use of the bindctl command tool to
	to the BIND 10 guide.
	(Trac #2305, git c4b0294b5bf4a9d32fb18ab62ca572f492788d72)

506.	[security]		jinmei
	Fixed a use-after-free case in handling DNAME record with the
	in-memory data source.  This could lead to a crash of b10-auth
	if it serves a zone containing a DNAME RR from the in-memory
	data source.  This bug was introduced at bind10-devel-20120927.
	(Trac #2471, git 2b1793ac78f972ddb1ae2fd092a7f539902223ff)

505.	[bug]		jelte
	Fixed a bug in b10-xfrin where a wrong call was made during the
	final check of a TSIG-signed transfer, incorrectly rejecting the
	transfer.
	(Trac #2464, git eac81c0cbebee72f6478bdb5cda915f5470d08e1)

504.	[bug]*		naokikambe
	Fixed an XML format viewed from b10-stats-httpd. Regarding
	per-zone counters as zones of Xfrout, a part of the item
	values wasn't an exact XML format. A zone name can be
	specified in URI as
	/bind10/statistics/xml/Xfrout/zones/example.org/xfrreqdone.
	XSD and XSL formats are also changed to constant ones due
	to these changes.
	(Trac #2298, git 512d2d46f3cb431bcdbf8d90af27bff8874ba075)

503.	[func]		Stephen
	Add initial version of a MySQL backend for the DHCP code.  This
	implements the basic IPv6 lease access functions - add lease, delete
	lease and update lease.  The backend is enabled by specifying
	--with-dhcp-mysql on the "configure" command line: without this
	switch, the MySQL code is not compiled, so leaving BIND 10 able to
	be built on systems without MySQL installed.
	(Trac #2342, git c7defffb89bd0f3fdd7ad2437c78950bcb86ad37)

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)

480.	[doc]		vorner
	Added documentation about global TSIG key ring to the Guide.
	(Trac #2189, git 52177bb31f5fb8e134aecb9fd039c368684ad2df)

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.

	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)

477.	[bug]		jelte
	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

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

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.

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

	We now set g+w and g+s permissions (mode 02770) during
	installation for the BIND 10 local state directory
	($prefix/var/bind10-devel/) so that permissions to files
	and sub-directories created in that directory are inherited.

460.	[bug]		muks
	SSHFP's algorithm and fingerprint type checks have been relaxed

458.	[build]*		jinmei
	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)
	(Trac #2147, git 30061d1139aad8716e97d6b620c259752fd0a3cd)

	BIND 10 library names now have a "b10-" prefix. This is to avoid
	clashes with other similarly named libraries on the system.

	BIND 10 now compiles against log4cplus-1.1.0 (RC releases)
	also.  Note: some older versions of log4cplus don't work any more;
	known oldest workable version is 1.0.4.  Thanks to John Lumby for
	sending a patch.

	The server now uses newer API for data sources. This would be an
	internal change, however, the data sources are now configured
	differently. Please, migrate your configuration to the top-level
	"data_sources" module.  Also the bind10 -n and --no-cache
	and b10-auth -n options are removed.
	(Trac #1976, git 0d4685b3e7603585afde1b587cbfefdfaf6a1bb3)

454.	[bug]		jelte
	b10-cfgmgr now loads its configuration check plugins directly from
	the plugin search path, as opposed to importing them from the
	general python system module path list; this prevents naming
	conflicts with real python modules.
	(Trac #2119, git 2f68d7ac5c3c7cc88a3663191113eece32d46a3d)

	b10-auth no longer tries to send DDNS UPDATE messages to b10-ddns if
	b10-ddns is not running. Sending an UPDATE to BIND 10 that is not
	configured to run DDNS will now result in a response with rcode
	NOTIMP instead of SERVFAIL.

	isc-sysinfo: An initial implementation of the isc-sysinfo
	tool is now available for Linux, OpenBSD, FreeBSD, and Mac
	OS X. It gathers and outputs system information which can

	libdatasrc: the database-based data source now correctly returns
	glue records on (not under) a zone cut, such as in the case where
	the NS name of an NS record is identical to its owner name. (Note:
	libdatasrc itself doesn't judge what kind of record type can be a
	"glue"; it's the caller's responsibility.)

	b10-xfin: fixed a bug where xfrin sent the wrong notification
	message to zonemgr on successful zone transfer. This also
	solves other reported problems such as too frequent attempts
	of zone refreshing (see Trac #1786 and #1834).

	b10-ddns is now functional and handles dynamic update requests
	per RFC 2136.  See BIND 10 guide for configuration and operation
	details.
	(Multiple Trac tickets)

447.	[bug]		jinmei
	Fixed a bug in b10-xfrout where a helper thread could fall into
	an infinite loop if b10-auth stops while the thread is waiting for
	forwarded requests from b10-auth.
	(Trac #988 and #1833, git 95a03bbefb559615f3f6e529d408b749964d390a)

445.	[bug]*		jinmei
	The pre-install check for older SQLite3 DB now refers to the DB
	file with the prefix of DESTDIR.  This ensures that 'make install'
	with specific DESTDIR works regardless of the version of the DB
	file installed in the default path.
	(Trac #1982, git 380b3e8ec02ef45555c0113ee19329fe80539f71)

	libdatasrc: fixed ZoneFinder for database-based data sources so
	that it handles type DS query correctly, i.e., treating it as
	authoritative data even on a delegation point.
	(Trac #1912, git 7130da883f823ce837c10cbf6e216a15e1996e5d)

443.	[func]*		muks
	The logger now uses a lockfile named `logger_lockfile' that is
	created in the local state directory to mutually separate
	individual logging operations from various processes. This is
	done so that log messages from different processes don't mix
	together in the middle of lines. The `logger_lockfile` is created
	with file permission mode 0660. BIND 10's local state directory
	should be writable and perhaps have g+s mode bit so that the
	`logger_lockfile` can be opened by a group of processes.

	Updated the DB schema used in the SQLite3 data source so it can
	use SQL indices more effectively.  The previous schema had several
	issues in this sense and could be very slow for some queries on a
	very large zone (especially for negative answers).  This change
	requires a major version up of the schema; use b10-dbutil to

413.	[func]		stephen, jelte
	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
	the March 29th release.  While running it shouldn't break
	an existing database file, it should be even more advisable not to
	run it at the moment.
	(Trac #963, git 49ba2cf8ac63246f389ab5e8ea3b3d081dba9adf)

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
	used if the configuration file is corrupted to the point where it
	cannot be read anymore, and BIND 10 refuses to start. The name of
	the backup file can be found in the logs (CFGMGR_RENAMED_CONFIG_FILE).

410.	[bug]		jinmei
	Python CC library now ensures write operations transmit all given
	data (unless an error happens).  Previously it didn't check the
	size of transmitted data, which could result in partial write on
	some systems (notably on OpenBSD) and subsequently cause system
	hang up or other broken state.  This fix specifically solves start
	up failure on OpenBSD.
	(Trac #1829, git 5e5a33213b60d89e146cd5e47d65f3f9833a9297)

405.	[bug]		jinmei
	Make sure disabling Boost threads if the default configuration is
	to disable it for the system.  This fixes a crash and hang up
	problem on OpenBSD, where the use of Boost thread could be
	different in different program files depending on the order of
	including various header files, and could introduce inconsistent
	states between a library and a program.  Explicitly forcing the

	items and per zone items. Also, modified b10-auth to use it. It is
	also intended to use in the other modules such as b10-resolver.
	(Trac #510, git afddaf4c5718c2a0cc31f2eee79c4e0cc625499f)

	Added IXFR-out system tests, based on the first two test sets of
	http://bind10.isc.org/wiki/IxfrSystemTests.

	In the resolver, a FORMERR received from an upstream nameserver
	now results in a SERVFAIL being returned as a response to the original
	query.  Additional debug messages added to distinguish between
	different errors in packets received from upstream nameservers.

	libdhcp++: Support for handling both IPv4 and IPv6 added.
	Also added support for binding IPv4 sockets.
	(Trac #1238, git 86a4ce45115dab4d3978c36dd2dbe07edcac02ac)

	Fixed several linker issues related to recent gcc versions, botan
	and gtest.
	(Trac #1442, git 91fb141bfb3aadfdf96f13e157a26636f6e9f9e3)

	libxfr, used by b10-auth to share TCP sockets with b10-xfrout,
	incorrectly propagated ASIO specific exceptions to the application
	if the given file name was too long.  This could lead to
	unexpected shut down of b10-auth.
	(Trac #1387, git a5e9d9176e9c60ef20c0f5ef59eeb6838ed47ab2)

338.	[bug]		jinmei
	b10-xfrin didn't check SOA serials of SOA and IXFR responses,
	which resulted in unnecessary transfer or unexpected IXFR
	timeouts (these issues were not overlooked but deferred to be
	fixed until #1278 was completed).  Validation on responses to SOA
	queries were tightened, too.
	(Trac #1299, git 6ff03bb9d631023175df99248e8cc0cda586c30a)

	libdhcp++: Support for DHCPv4 option that can store a single
	address or a list of IPv4 addresses added. Support for END option
	added.

	libdns++ (and its python wrapper) now includes a class Serial, for
	SOA SERIAL comparison and addition. Operations on instances of this
	class follow the specification from RFC 1982.
	Rdata::SOA::getSerial() now returns values of this type (and not
	uint32_t).

335.	[bug]*		jelte
	The DataSourceClientContainer class that dynamically loads
	datasource backend libraries no longer provides just a .so file name
	to its call to dlopen(), but passes it an absolute path. This means
	that it is no longer an system implementation detail that depends on
	[DY]LD_LIBRARY_PATH which file is chosen, should there be multiple
	options (for instance, when test-running a new build while a
	different version is installed).
	These loadable libraries are also no longer installed in the default
	library path, but in a subdirectory of the libexec directory of the
	target ($prefix/libexec/[version]/backends).
	This also removes the need to handle b10-xfin and b10-xfrout as
	'special' hardcoded components, and they are now started as regular
	components as dictated by the configuration of the boss process.
	(Trac #1292, git 83ce13c2d85068a1bec015361e4ef8c35590a5d0)

334.	[bug]		jinmei
	b10-xfrout could potentially create an overflow response message
	(exceeding the 64KB max) or could create unnecessarily small
	messages.  The former was actually unlikely to happen due to the
	effect of name compression, and the latter was marginal and at least
	shouldn't cause an interoperability problem, but these were still
	potential problems and were fixed.

	Solaris needs "-z now" to force non-lazy binding and prevent
	g++ static initialization code from deadlocking.

	C++ exceptions in the isc.dns.Rdata wrapper are now converted
	to python ones instead of just aborting the interpreter.

bind10-devel-20111128 released on November 28, 2011

331.	[bug]		shane
	Fixed a bug in data source library where a zone with more labels
	than an out-of-bailiwick name server would cause an exception to
	be raised.
	(Trac #1430, git 81f62344db074bc5eea3aaf3682122fdec6451ad)

330.	[bug]		jelte
	Fixed a bug in b10-auth where it would sometimes fail because it
	tried to check for queued msgq messages before the session was
	fully running.
	(git c35d0dde3e835fc5f0a78fcfcc8b76c74bc727ca)

329.	[doc]		vorner, jreed
	Document the bind10 run control configuration in guide and
	manual page.

	b10-auth now passes IXFR requests on to b10-xfrout, and no longer
	responds to them with NOTIMPL.
	(Trac #1390, git ab3f90da16d31fc6833d869686e07729d9b8c135)

327.	[func]		jinmei
	b10-xfrout now supports IXFR.  (Right now there is no user
	configurable parameter about this feature; b10-xfrout will
	always respond to IXFR requests according to RFC1995).
	(Trac #1371 and #1372, git 80c131f5b0763753d199b0fb9b51f10990bcd92b)

326.	[build]*		jinmei
	Added a check script for the SQLite3 schema version.  It will be
	run at the beginning of 'make install', and if it detects an old
	version of schema, installation will stop.  You'll then need to
	upgrade the database file by following the error message.
	(Trac #1404, git a435f3ac50667bcb76dca44b7b5d152f45432b57)

325.	[func]		jinmei
	Python isc.datasrc: added interfaces for difference management:
	DataSourceClient.get_updater() now has the 'journaling' parameter
	to enable storing diffs to the data source, and a new class
	ZoneJournalReader was introduced to retrieve them, which can be
	created by the new DataSourceClient.get_journal_reader() method.
