ChangeLog

xxx.	[bug]		naokikambe
	Fix inconsistent statistics counts of Auth via bindctl or
	b10-stats-httpd while multiple b10-auth instances are running. Each
	count of Auth is accumulated across the instances except an inactive
	instances. Introduce a pid argument into the set command of b10-stats
	so that b10-stats identifies which instance sends by the PID which the
	b10-auth instance sends together with statistics data. Also add a
	regression check into systest against that inconsistency.
	(Trac #1751, git TBD)

401.	[func]*		jinmei
	libdns++: updated the internal implementation of the
	MessageRenderer class.  This is mostly a transparent change, but
	the new version now doesn't allow changing compression mode in the
	middle of rendering (which shouldn't be an issue in practice).
	On the other hand, name compression performance was significantly
	improved: depending on the number of names, micro benchmark tests
	showed the new version is several times faster than the previous
	version .
	(Trac #1603, git 9a2a86f3f47b60ff017ce1a040941d0c145cfe16)

	Fix crash on Max OS X 10.7 by altering logging so as not to allocate
	heap storage in the static initialization of logging objects.
	(Trac #1698, git a8e53be7039ad50d8587c0972244029ff3533b6e)

399.	[func]		muks
	Add support for the SSHFP RR type (RFC 4255).
	(Trac #1136, git ea5ac57d508a17611cfae9d9ea1c238f59d52c51)

398.	[func]		jelte
	The b10-xfrin module now logs more information on successful
	incoming transfers. In the case of IXFR, it logs the number of
	changesets, and the total number of added and deleted resource
	records. For AXFR (or AXFR-style IXFR), it logs the number of
	resource records. In both cases, the number of overhead DNS
	messages, runtime, amount of wire data, and transfer speed are logged.
	(Trac #1280, git 2b01d944b6a137f95d47673ea8367315289c205d)

397.	[func]		muks
	The boss process now gives more helpful description when a
	sub-process exits due to a signal.
	(Trac #1673, git 1cd0d0e4fc9324bbe7f8593478e2396d06337b1e)

396.	[func]*		jinmei
	libdatasrc: change the return type of ZoneFinder::find() so it can
	contain more context of the search, which can be used for
	optimizing post find() processing.  A new method getAdditional()
	is added to it for finding additional RRsets based on the result
	of find().  External behavior shouldn't change.  The query
	handling code of b10-auth now uses the new interface.
	(Trac #1607, git 2e940ea65d5b9f371c26352afd9e66719c38a6b9)

395.	[bug]		jelte
	The log message compiler now errors (resulting in build failures) if
	duplicate log message identifiers are found in a single message file.
	Renamed one duplicate that was found (RESOLVER_SHUTDOWN, renamed to
	RESOLVER_SHUTDOWN_RECEIVED).
	(Trac #1093, git f537c7e12fb7b25801408f93132ed33410edae76)

394.	[bug]		jelte
	b10-auth now catches any exceptions during response building; if any
	datasource either throws an exception or causes an exception to be
	thrown, the message processing code will now catch it, log a debug
	message, and return a SERVFAIL response.
	(Trac #1612, git b5740c6b3962a55e46325b3c8b14c9d64cf0d845)

393.	[func]		jelte
	Introduced a new class LabelSequence in libdns++, which provides
	lightweight accessor functionality to the Name class, for more
	efficient comparison of parts of names.
	(Trac #1602, git b33929ed5df7c8f482d095e96e667d4a03180c78)

392.	[func]*		jinmei
	libdns++: revised the (Abstract)MessageRenderer class so that it
	has a default internal buffer and the buffer can be temporarily
	switched.  The constructor interface was modified, and a new
	method setBuffer() was added.
	(Trac #1697, git 9cabc799f2bf9a3579dae7f1f5d5467c8bb1aa40)

391.	[bug]*		vorner
	The long time unused configuration options of Xfrout "log_name",
	"log_file", "log_severity", "log_version" and "log_max_bytes" were
	removed, as they had no effect (Xfrout uses the global logging
	framework).  However, if you have them set, you need to remove
	them from the configuration file or the configuration will be
	rejected.
	(Trac #1090, git ef1eba02e4cf550e48e7318702cff6d67c1ec82e)

bind10-devel-20120301 released on March 1, 2012

390.	[bug]		vorner
	The UDP IPv6 packets are now correctly fragmented for maximum
	guaranteed MTU, so they won't get lost because being too large
	for some hop.
	(Trac #1534, git ff013364643f9bfa736b2d23fec39ac35872d6ad)

389.	[func]*		vorner
	Xfrout now uses the global TSIG keyring, instead of its own. This
	means the keys need to be set only once (in tsig_keys/keys).
	However, the old configuration of Xfrout/tsig_keys need to be
	removed for Xfrout to work.
	(Trac #1643, git 5a7953933a49a0ddd4ee1feaddc908cd2285522d)

388.	[func]		jreed
	Use prefix "sockcreator-" for the private temporary directory
	used for b10-sockcreator communication.
	(git b98523c1260637cb33436964dc18e9763622a242)

387.	[build]		muks
	Accept a --without-werror configure switch so that some builders can
	disable the use of -Werror in CFLAGS when building.
	(Trac #1671, git 8684a411d7718a71ad9fb616f56b26436c4f03e5)

386.	[bug]		jelte
	Upon initial sqlite3 database creation, the 'diffs' table is now
	always created. This already happened most of the time, but there
	are a few cases where it was skipped, resulting in potential errors
	in xfrout later.
	(Trac #1717, git 30d7686cb6e2fa64866c983e0cfb7b8fabedc7a2)

385.	[bug]		jinmei
	libdns++: masterLoad() didn't accept comments placed at the end of
	an RR.  Due to this the in-memory data source cannot load a master
	file for a signed zone even if it's preprocessed with BIND 9's
	named-compilezone.
	Note: this fix is considered temporary and still only accepts some
	limited form of such comments.  The main purpose is to allow the
	in-memory data source to load any signed or unsigned zone files as
	long as they are at least normalized with named-compilezone.
	(Trac #1667, git 6f771b28eea25c693fe93a0e2379af924464a562)

384.	[func]		jinmei, jelte, vorner, haikuo, kevin
	b10-auth now supports NSEC3-signed zones in the in-memory data
	source.
	(Trac #1580, #1581, #1582, #1583, #1584, #1585, #1587, and
	other related changes to the in-memory data source)

383.	[build]		jinmei
	Fixed build failure on MacOS 10.7 (Lion) due to the use of
	IPV6_PKTINFO; the OS requires a special definition to make it
	visible to the compiler.
	(Trac #1633, git 19ba70c7cc3da462c70e8c4f74b321b8daad0100)

382.	[func]		jelte
	b10-auth now also experimentally supports statistics counters of
	the rcode responses it sends. The counters can be shown as
	rcode.<code name>, where code name is the lowercase textual
	representation of the rcode (e.g. "noerror", "formerr", etc.).
	Same note applies as for opcodes, see changelog entry 364.

	b10-auth: honor the DNSSEC DO bit in the new query handler.
	(Trac #1695, git 61f4da5053c6a79fbc162fb16f195cdf8f94df64)

380.	[bug]		jinmei
	libdns++: miscellaneous bug fixes for the NSECPARAM RDATA
	implementation, including incorrect handling for empty salt and
	incorrect comparison logic.
	(Trac #1638, git 966c129cc3c538841421f1e554167d33ef9bdf25)

379.	[bug]		jelte
	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").
	(Trac #1649, git 003ca8597c8d0eb558b1819dbee203fda346ba77)

378.	[func]		vorner
	It is possible to start authoritative server or resolver in multiple
	instances, to use more than one core. Configuration is described in
	the guide.
	(Trac #1596, git 17f7af0d8a42a0a67a2aade5bc269533efeb840a)

377.	[bug]		jinmei
	libdns++: miscellaneous bug fixes for the NSEC and NSEC3 RDATA
	implementation, including a crash in NSEC3::toText() for some RR
	types, incorrect handling of empty NSEC3 salt, and incorrect
	comparison logic in NSEC3::compare().
	(Trac #1641, git 28ba8bd71ae4d100cb250fd8d99d80a17a6323a2)

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.
	(Trac #1570, git 2858b2098a10a8cc2d34bf87463ace0629d3670e)

375.	[func]		jelte
	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
	command or configuration update.  Previously this would result
	in a 'not responding' error instead of 'not running'.
	(Trac #640, git 17e78fa1bb1227340aa9815e91ed5c50d174425d)

374.	[func]*		stephen
	Alter RRsetPtr and ConstRRsetPtr to point to AbstractRRset (instead
	of RRset) to allow for specialised implementations of RRsets in
	data sources.
	(Trac #1604, git 3071211d2c537150a691120b0a5ce2b18d010239)

373.	[bug]		jinmei
	libdatasrc: the in-memory data source incorrectly rejected loading
	a zone containing a CNAME RR with RRSIG and/or NSEC.
	(Trac #1551, git 76f823d42af55ce3f30a0d741fc9297c211d8b38)

372.	[func]		vorner
	When the allocation of a socket fails for a different reason than the
	socket not being provided by the OS, the b10-auth and b10-resolver
	abort, as the system might be in inconsistent state after such error.
	(Trac #1543, git 49ac4659f15c443e483922bf9c4f2de982bae25d)

371.	[bug]		jelte
	The new query handling module of b10-auth (currently only used with
	the in-memory data source) now correctly includes the DS record (or
	the denial of its existence if NSEC is used) when returning a
	delegation from a signed zone.
	(Trac #1573, git bd7a3ac98177573263950303d4b2ea7400781d0f)

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)

	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.

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, #1509, #1510,

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)

	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)

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.

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.

	The target parameter of ZoneFinder::find is no longer present, as the

	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)

	In the resolver, a FORMERR received from an upstream nameserver
	now results in a SERVFAIL being returned as a response to the original

	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.

	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 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

bind10-devel-20110819 released on August 19, 2011

281.	[func]		jelte
	Added a new type for configuration data: "named set". This allows for
	similar configuration as the current "list" type, but with strings
	instead of indices as identifiers. The intended use is for instance
	/foo/zones/example.org/bar instead of /foo/zones[2]/bar. Currently
	this new type is not in use yet.

276.	[func]		stephen
	Although the top-level loggers are named after the program (e.g.
	b10-auth, b10-resolver), allow the logger configuration to omit the
	"b10-" prefix and use just the module name.
	(Trac #1003, git a01cd4ac5a68a1749593600c0f338620511cae2d)

275.	[func]		jinmei
	Added support for TSIG key matching in ACLs.  The xfrout ACL can
	now refer to TSIG key names using the "key" attribute.  For
	example, the following specifies an ACL that allows zone transfer
	if and only if the request is signed with a TSIG of a key name
	"key.example":
	> config set Xfrout/query_acl[0] {"action": "ACCEPT", \
	                                  "key": "key.example"}

274.	[bug]		naokikambe
	add unittests for functions xml_handler, xsd_handler and xsl_handler
	respectively to make sure their behaviors are correct, regardless of
	whether type which xml.etree.ElementTree.tostring() after Python3.2
	returns is str or byte.
	(Trac #1021, git 486bf91e0ecc5fbecfe637e1e75ebe373d42509b)

273.	[func]		vorner
	It is possible to specify ACL for the xfrout module. It is in the ACL
	configuration key and has the usual ACL syntax. It currently supports
	only the source address. Default ACL accepts everything.
	(Trac #772, git 50070c824270d5da1db0b716db73b726d458e9f7)

	libdns++/pydnspp: TSIG signing now handles truncated DNS messages
	(i.e. with TC bit on) with TSIG correctly.
	(Trac #910, 8e00f359e81c3cb03c5075710ead0f87f87e3220)

271.	[func]		stephen
	Default logging for unit tests changed to severity DEBUG (level 99)
	with the output routed to /dev/null.  This can be altered by setting
	the B10_LOGGER_XXX environment variables.
	(Trac #1024, git 72a0beb8dfe85b303f546d09986461886fe7a3d8)

270.	[func]		jinmei
	Added python bindings for ACLs using the DNS request as the
	context.  They are accessible via the isc.acl.dns module.
	(Trac #983, git c24553e21fe01121a42e2136d0a1230d75812b27)

269.	[bug]		y-aharen
	Modified IntervalTimerTest not to rely on the accuracy of the timer.
	This fix addresses occasional failure of build tests.
	(Trac #1016, git 090c4c5abac33b2b28d7bdcf3039005a014f9c5b)

268.	[func]		stephen
	Add environment variable to allow redirection of logging output during
	unit tests.

bind10-devel-20110705 released on July 05, 2011

267.	[func]		tomek
	Added a dummy module for DHCP6. This module does not actually
	do anything at this point, and BIND 10 has no option for
	starting it yet. It is included as a base for further
	development.
	(Trac #990, git 4a590df96a1b1d373e87f1f56edaceccb95f267d)

266.	[func]		Multiple developers
        Convert various error messages, debugging and other output
        to the new logging interface, including for b10-resolver,
        the resolver library, the CC library, b10-auth, b10-cfgmgr,
        b10-xfrin, and b10-xfrout. This includes a lot of new
        documentation describing the new log messages.
        (Trac #738, #739, #742, #746, #759, #761, #762)

265.	[func]*		jinmei
	b10-resolver: Introduced ACL on incoming queries.  By default the
	resolver accepts queries from ::1 and 127.0.0.1 and rejects all
	others.  The ACL can be configured with bindctl via the
	"Resolver/query_acl" parameter.  For example, to accept queries
	from 192.0.2.0/24 (in addition to the default list), do this:
	> config add Resolver/query_acl
	> config set Resolver/query_acl[2]/action "ACCEPT"
	> config set Resolver/query_acl[2]/from "192.0.2.0/24"
	> config commit
	(Trac #999, git e0744372924442ec75809d3964e917680c57a2ce,
	also based on other ACL related work done by stephen and vorner)

264.	[bug]		jerry
	b10-xfrout: fixed a busy loop in its notify-out subthread.  Due to
	the loop, the thread previously woke up every 0.5 seconds throughout
	most of the lifetime of b10-xfrout, wasting the corresponding CPU
	time.
	(Trac #1001, git fb993ba8c52dca4a3a261e319ed095e5af8db15a)

263.	[func]		jelte
	Logging configuration can now also accept a * as a first-level
	name (e.g. '*', or '*.cache'), indicating that every module
	should use that configuration, unless overridden by an explicit
	logging configuration for that module
	(Trac #1004, git 0fad7d4a8557741f953eda9fed1d351a3d9dc5ef)

262.	[func]		stephen
	Add some initial documentation about the logging framework.
	Provide BIND 10 Messages Manual in HTML and DocBook? XML formats.
	This provides all the log message descriptions in a single document.
	A developer tool, tools/system_messages.py (available in git repo),
	was written to generate this.
	(Trac #1012, git 502100d7b9cd9d2300e78826a3bddd024ef38a74)

	text in the new-style logging messages.
	(Trac #1031, git 1c7930a7ba19706d388e4f8dcf2a55a886b74cd2)

259.	[bug]		stephen
	Logging now correctly initialized in b10-auth.  Also, fixed
	bug whereby querying for "version.bind txt ch" would cause
	b10-auth to crash if BIND 10 was started with the "-v" switch.
	(Trac #1022,#1023, git 926a65fa08617be677a93e9e388df0f229b01067)

257.	[bug]		y-aharen
	Fixed a bug an instance of IntervalTimerImpl may be destructed 
	while deadline_timer is holding the handler. This fix addresses
	occasional failure of IntervalTimerTest.destructIntervalTimer.

251.	[bug]*		jinmei
	Make sure bindctl private files are non readable to anyone except
	the owner or users in the same group.  Note that if BIND 10 is run
	with changing the user, this change means that the file owner or
	group will have to be adjusted.  Also note that this change is
	only effective for a fresh install; if these files already exist,
	their permissions must be adjusted by hand (if necessary).
