ChangeLog

370.	[func]		jinmei
	libdns++: a new class NSEC3Hash was introduced as a utility for
	calculating NSEC3 hashes for various purposes.  Python binding was
	provided, too.  Also fixed a small bug in the NSEC3PARAM RDATA
	implementation that empty salt in text representation was
	rejected.
	(Trac #1575, git 2c421b58e810028b303d328e4e2f5b74ea124839)

369.	[func]		vorner
	The SocketRequestor provides more information about what error happened
	when it throws, by using subclasses of the original exception. This way
	a user not interested in the difference can still use the original
	exception, while it can be recognized if necessary.
	(Trac #1542, git 2080e0316a339fa3cadea00e10b1ec4bc322ada0)

368.	[func]*		jinmei
	libdatasrc: the interface of ZoneFinder() was changed: WILDCARD
	related result codes were deprecated and removed, and the
	corresponding information is now provided via a separate accessor
	method on FindResult.  Other separate FindResult methods will
	also tell the caller whether the zone is signed with NSEC or NSEC3
	(when necessary and applicable).
	(Trac #1611, git c175c9c06034b4118e0dfdbccd532c2ebd4ba7e8)

367.	[bug]		jinmei
	libdatasrc: in-memory data source could incorrectly reject to load
	zones containing RRSIG records.  For example, it didn't allow
	RRSIG that covers a CNAME RR.  This fix also makes sure find()
	will return RRsets with RRSIGs if they are signed.
	(Trac #1614, git e8241ea5a4adea1b42a60ee7f2c5cfb87301734c)

366.	[bug]		vorner
	Fixed problem where a directory named "io" conflicted with the python3
	standard module "io" and caused the installation to fail.  The
	offending directory has been renamed to "cio".
	(Trac #1561, git d81cf24b9e37773ba9a0d5061c779834ff7d62b9)

365.	[bug]		jinmei
	libdatasrc: in-memory datasource incorrectly returned delegation
	for DS lookups.
	(Trac #1571, git d22e90b5ef94880183cd652e112399b3efb9bd67)

364.	[func]		jinmei
	b10-auth experimentally supports statistics counters of incoming
	requests per opcode.  The counters can be (e.g.) shown as
	opcode.<code name> in the output of the bindctl "Stats show"
	command, where <code name> is lower-cased textual representation
	of opcodes ("query", "notify", etc).
	Note: This is an experimental attempt of supporting more
	statistics counters for b10-auth, and the interface and output may
	change in future versions.
	(Trac #1399, git 07206ec76e2834de35f2e1304a274865f8f8c1a5)

bind10-devel-20120119 released on January 19, 2012

363.	[func]		jelte
	Added dummy DDNS module b10-ddns. Currently it does not
	provide any functionality, but it is a skeleton implementation
	that will be expanded later.
	(Trac #1451, git b0d0bf39fbdc29a7879315f9b8e6d602ef3afb1b)

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.
	(Trac #1508-#1510, git edc5b3c12eb45437361484c843794416ad86bb00)

361.	[func]		vorner,jelte,jinmei
	The socket creator is now used to provide sockets. It means you can
	reconfigure the ports and addresses at runtime even when the rest
	of the bind10 runs as non root user.
	(Trac #805,#1522, git 1830215f884e3b5efda52bd4dbb120bdca863a6a)

360.	[bug]		vorner
	Fixed problem where bindctl crashed when a duplicate non-string
	item was added  to a list.  This error is now properly reported.
	(Trac #1515, git a3cf5322a73e8a97b388c6f8025b92957e5d8986)

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.
	(Trac #1462, git ceeb87f6d539c413ebdc66e4cf718e7eb8559c45)

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).
	(Trac #1424, git 2cba8cb83cde4f34842898a848c0b1182bc20597)

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).
	(Trac #1430, git b35797ba1a49c78246abc8f2387901f9690b328d)

356.	[doc]		tomek
	BIND10 Guide updated. It now describes DHCPv4 and DHCPv6
	components, including their overview, usage, supported standard
	and limitations. libdhcp++ is also described.
	(Trac #1367, git 3758ab360efe1cdf616636b76f2e0fb41f2a62a0)

355.	[bug]		jinmei
	Python xfrin.diff module incorrectly combined RRSIGs of different
	type covered, possibly merging different TTLs.  As a result a
	secondary server could store different RRSIGs than those at the
	primary server if it gets these records via IXFR.
	(Trac #1502, git 57b06f8cb6681f591fa63f25a053eb6f422896ef)

354.	[func]		tomek
	dhcp4: Support for DISCOVER and OFFER implemented. b10-dhcp4 is
	now able to offer hardcoded leases to DHCPv4 clients.
	dhcp6: Code refactored to use the same approach as dhcp4.
	(Trac #1230, git aac05f566c49daad4d3de35550cfaff31c124513)

353.	[func]		tomek
	libdhcp++: Interface detection in Linux implemented. libdhcp++
	is now able (on Linux systems) to detect available network
	interfaces, its link-layer addresses, flags and configured
	IPv4 and IPv6 addresses. Interface detection on other
	systems is planned.
	(Trac #1237, git 8a040737426aece7cc92a795f2b712d7c3407513)

352.	[func]		tomek
	libdhcp++: Transmission and reception of DHCPv4 packets is now
	implemented. Low-level hacks are not implemented for transmission
	to hosts that don't have IPv4 address yet, so currently the code
	is usable for communication with relays only, not hosts on the
	same link.
	(Trac #1239, #1240, git f382050248b5b7ed1881b086d89be2d9dd8fe385)

351.	[func]		fdupont
	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
	and SA).  More information can be obtained by invoking the utility
	(in tests/tools/perfdhcp) with the "-h" flag.
	(Trac #1450, git 85083a76107ba2236732b45524ce7018eefbaf90)

350.	[func]*		vorner
	The target parameter of ZoneFinder::find is no longer present, as the
	interface was awkward. To get all the RRsets of a single domain, use
	the new findAll method (the same applies to python version, the method
	is named find_all).
	(Trac #1483,#1484, git 0020456f8d118c9f3fd6fc585757c822b79a96f6)

349.	[bug]		dvv
	resolver: If an upstream server responds with FORMERR to an EDNS
	query, try querying it without EDNS.
	(Trac #1386, git 99ad0292af284a246fff20b3702fbd7902c45418)

348.	[bug]		stephen
	By default the logging output stream is now flushed after each write.
	This fixes a problem seen on some systems where the log output from
	different processes was jumbled up.  Flushing can be disabled by
	setting the appropriate option in the logging configuration.
	(Trac #1405, git 2f0aa20b44604b671e6bde78815db39381e563bf)

347.	[bug]		jelte
	Fixed a bug where adding Zonemgr/secondary_zones without explicitly
	setting the class value of the added zone resulted in a cryptic
	error in bindctl ("Error: class"). It will now correctly default to
	IN if not set. This also adds better checks on the name and class
	values, and better errors if they are bad.
	(Trac #1414, git 7b122af8489acf0f28f935a19eca2c5509a3677f)

346.	[build]*		jreed
	Renamed libdhcp to libdhcp++.
	(Trac #1446, git d394e64f4c44f16027b1e62b4ac34e054b49221d)

345.	[func]		tomek
	dhcp4: Dummy DHCPv4 component implemented. Currently it does
	nothing useful, except providing skeleton implementation that can
	be expanded in the future.
	(Trac #992, git d6e33479365c8f8f62ef2b9aa5548efe6b194601)

344.	[func]		y-aharen
	src/lib/statistics: Added statistics counter library for entire server
	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)

343.	[func]		jelte
	Added IXFR-out system tests, based on the first two test sets of
	http://bind10.isc.org/wiki/IxfrSystemTests.
	(Trac #1314, git 1655bed624866a766311a01214597db01b4c7cec)

342.	[bug]		stephen
	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.
	(Trac #1383, git 9b2b249d23576c999a65d8c338e008cabe45f0c9)

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

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

339.	[bug]		jinmei
	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)

337.	[func]		tomek
	libdhcp++: Support for DHCPv4 option that can store a single
	address or a list of IPv4 addresses added. Support for END option
	added.
	(Trac #1350, git cc20ff993da1ddb1c6e8a98370438b45a2be9e0a)

336.	[func]		jelte
	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).
	(Trac #1278, git 2ae72d76c74f61a67590722c73ebbf631388acbd)

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.
	(Trac #1389, git 3fdce88046bdad392bd89ea656ec4ac3c858ca2f)

333.	[bug]		dvv
	Solaris needs "-z now" to force non-lazy binding and prevent
	g++ static initialization code from deadlocking.
	(Trac #1439, git c789138250b33b6b08262425a08a2a0469d90433)

332.	[bug]		vorner
	C++ exceptions in the isc.dns.Rdata wrapper are now converted
	to python ones instead of just aborting the interpreter.
	(Trac #1407, git 5b64e839be2906b8950f5b1e42a3fadd72fca033)

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.
	(Trac #1341, git c1171699a2b501321ab54207ad26e5da2b092d63)

328.	[func]		jelte
	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.
	(Trac #1333, git 3e19362bc1ba7dc67a87768e2b172c48b32417f5,
	git 39def1d39c9543fc485eceaa5d390062edb97676)

324.	[bug]		jinmei
	Fixed reference leak in the isc.log Python module.  Most of all
	BIND 10 Python programs had memory leak (even though the pace of
	leak may be slow) due to this bug.
	(Trac #1359, git 164d651a0e4c1059c71f56b52ea87ac72b7f6c77)

323.	[bug]		jinmei
	b10-xfrout incorrectly skipped adding TSIG RRs to some
	intermediate responses (when TSIG is to be used for the
	responses).  While RFC2845 optionally allows to skip intermediate
	TSIGs (as long as the digest for the skipped part was included
	in a later TSIG), the underlying TSIG API doesn't support this
	mode of signing.
	(Trac #1370, git 76fb414ea5257b639ba58ee336fae9a68998b30d)

322.	[func]		jinmei
	datasrc: Added C++ API for retrieving difference of two versions
	of a zone.  A new ZoneJournalReader class was introduced for this
	purpose, and a corresponding factory method was added to
	DataSourceClient.
	(Trac #1332, git c1138d13b2692fa3a4f2ae1454052c866d24e654)

321.	[func]*		jinmei
	b10-xfrin now installs IXFR differences into the underlying data
	source (if it supports journaling) so that the stored differences
	can be used for subsequent IXFR-out transactions.
	Note: this is a backward incompatibility change for older sqlite3
	database files.  They need to be upgraded to have a "diffs" table.
	(Trac #1376, git 1219d81b49e51adece77dc57b5902fa1c6be1407)

320.	[func]*		vorner
	The --brittle switch was removed from the bind10 executable.
	It didn't work after change #316 (Trac #213) and the same
	effect can be accomplished by declaring all components as core.
	(Trac #1340, git f9224368908dd7ba16875b0d36329cf1161193f0)

319.	[func]		naokikambe
	b10-stats-httpd was updated. In addition of the access to all
	statistics items of all modules, the specified item or the items
	of the specified module name can be accessed.  For example, the
	URI requested by using the feature is showed as
	"/bind10/statistics/xml/Auth" or
	"/bind10/statistics/xml/Auth/queries.tcp". The list of all possible
	module names and all possible item names can be showed in the
	root document, whose URI is "/bind10/statistics/xml".  This change
	is not only for the XML documents but also is for the XSD and
	XSL documents.

	datasrc: the getUpdater method of DataSourceClient supports an
	optional 'journaling' parameter to indicate the generated updater
	to store diffs.  The database based derived class implements this
	extension.

	libdhcp: Support for DHCPv4 packet manipulation is now implemented.
	All fixed fields are now supported. Generic support for DHCPv4
	options is available (both parsing and assembly). There is no code
	that uses this new functionality yet, so it is not usable directly
	at this time. This code will be used by upcoming b10-dhcp4 daemon.
	(Trac #1228, git 31d5a4f66b18cca838ca1182b9f13034066427a7)

314.	[bug]		jelte
	b10-xfrin would previously initiate incoming transfers upon 
	receiving NOTIFY messages from any address (if the zone was 
	known to b10-xfrin, and using the configured address). It now 
	only starts a transfer if the source address from the NOTIFY 
	packet matches the configured master address and port. This was 
	really already fixed in release bind10-devel-20111014, but there 
	were some deferred cleanups to add.

313.	[func]		jinmei
	datasrc: Added C++ API for adding zone differences to database
	based data sources.  It's intended to be used for the support for
	IXFR-in and dynamic update (so they can subsequently be retrieved
	for IXFR-out).  The addRecordDiff method of the DatabaseAccessor
	defines the interface, and a concrete implementation for SQLite3
	was provided.
	(Trac #1329, git 1aa233fab1d74dc776899df61181806679d14013)

312.	[func]		jelte
	Added an initial framework for doing system tests using the 
	cucumber-based BDD tool Lettuce. A number of general steps are
	included,  for instance running bind10 with specific
	configurations, sending queries, and inspecting query answers. A
	few very basic tests are included as well.

	libdhcp: DHCP packet library was implemented. Currently it handles
	packet reception, option parsing, option generation and output
	packet building. Generic and specialized classes for several
	DHCPv6 options (IA_NA, IAADDR, address-list) are available. A
	simple code was added that leverages libdhcp. It is a skeleton
	DHCPv6 server. It receives incoming SOLICIT and REQUEST messages
	and responds with proper ADVERTISE and REPLY. Note that since
	LeaseManager is not implemented, server assigns the same
	hardcoded lease for every client. This change removes existing
	DHCPv6 echo server as it was only a proof of concept code.

	b10-xfrout: ACLs for xfrout can now be configured per zone basis.
	A per zone ACL is part of a more general zone configuration.  A
	quick example for configuring an ACL for zone "example.com" that
	rejects any transfer request for that zone is as follows:
	> config add Xfrout/zone_config
	> config set Xfrout/zone_config[0]/origin "example.com"
	> config add Xfrout/zone_config[0]/transfer_acl
	> config set Xfrout/zone_config[0]/transfer_acl[0] {"action": "REJECT"}
	The previous global ACL (query_acl) was renamed to transfer_acl,
	which now works as the default ACL.  Note: backward compatibility
	is not provided, so an existing configuration using query_acl
	needs to be updated by hand.
	Note: the per zone configuration framework is a temporary
	workaround.  It will eventually be redesigned as a system wide
	configuration.

	(configured in tsig_keys/keys, list of strings like
	"name:<base64-secret>:sha1-hmac"). It doesn't use them for
	ACL yet, only verifies them and signs if the request is signed.

	In unit tests, allow the choice of whether unhandled exceptions are
	caught in the unit test program (and details printed) or allowed to
	propagate to the default exception handler.  See the bind10-dev thread
	https://lists.isc.org/pipermail/bind10-dev/2011-January/001867.html
	for more details.

	xfrin: added support for TSIG verify.  This change completes TSIG
	support in b10-xfrin.

	pydnspp: added python extension for the TSIG API introduced in
	change 235.

	Updated configuration options to Xfrin, so that you can specify
	a master address, port, and TSIG key per zone. Still only one per
	zone at this point, and TSIG keys are (currently) only specified
	by their full string representation. This replaces the
	Xfrin/master_addr, Xfrin/master_port, and short-lived
	Xfrin/tsig_key configurations with a Xfrin/zones list.

	src/bin/xfrout: If a zone doesn't have notify slaves (only has
	one apex ns record - the primary master name server) will cause
	b10-xfrout uses 100% of CPU.

	Implement the simplest forwarder, which pass everything through
	except QID, port number. The response will not be cached.

237.	[bug]		naokikambe
	Resolved that the stats module wasn't configurable in bindctl in
	spite of its having configuration items. The configuration part
	was removed from the original spec file "stats.spec" and was
	placed in a new spec file "stats-schema.spec". Because it means
	definitions of statistics items. The command part is still
	there. Thus stats module currently has no its own configuration,
	and the items in "stats-schema.spec" are neither visible nor
	configurable through bindctl. "stats-schema.spec" is shared with
	stats module and stats-httpd module, and maybe with other
	statistical modules in future. "stats.spec" has own configuration
	and commands of stats module, if it requires.

	C++ client side of configuration now uses BIND10 logging system.
	It also has improved error handling when communicating with the
	rest of the system.

	libdns++: added support for TSIG signing and verification.  It can
	be done using a newly introduced TSIGContext class.
	Note: we temporarily disabled support for truncated signature
	and modified some part of the code introduced in #226 accordingly.
	We plan to fix this pretty soon.

	src/bin/xfrin: update xfrin to use TSIG. Currently it only supports
	sending a signed TSIG request or SOA request.

	To facilitate the writing of extended descriptions in
	message files, altered the message file format.  The message
	is now flagged with a "%" as the first non-blank character
	in the line and the lines in the extended description are
	no longer preceded by a "+".
	(Trac #900, git b395258c708b49a5da8d0cffcb48d83294354ba3)

231.	[func]*		vorner
    The logging interface changed slightly. We use
	logger.foo(MESSAGE_ID).arg(bar); instead of logger.foo(MESSAGE_ID,
	bar); internally. The message definitions use '%1,%2,...'
	instead of '%s,%d', which allows us to cope better with
	mismatched placeholders and allows reordering of them in
	case of translation.
	(Trac #901, git 4903410e45670b30d7283f5d69dc28c2069237d6)

230.	[bug]		naokikambe
	Removed too repeated verbose messages in two cases of:
	 - when auth sends statistics data to stats
	 - when stats receives statistics data from other modules

	Add manual page for b10-host.
	(git a437d4e26b81bb07181ff35a625c540703eee845)

228.	[func]*		jreed
	The host tool is renamed to b10-host. While the utility is
	a work in progress, it is expected to now be shipped with
	tarballs. Its initial goal was to be a host(1) clone,
	rewritten in C++ from scratch and using BIND 10's libdns++.
	It now supports the -a (any), -c class, -d (verbose) switches
	and has improved output.
	(Trac #872, git d846851699d5c76937533adf9ff9d948dfd593ca)

227.	[build]		jreed
	Add missing libdns++ rdata files for the distribution (this
	fixes distcheck error). Change three generated libdns++
	headers to "nodist" so they aren't included in the distribution
	(they were mistakenly included in last tarball).

226.	[func]*		jelte
	Introduced an API for cryptographic operations. Currently it only
	supports HMAC, intended for use with TSIG. The current
	implementation uses Botan as the backend library.
	This introduces a new dependency, on Botan.  Currently only Botan
	1.8.x works; older or newer versions don't.
