CHANGES

4812.	[bug]		Minor improvements to stability and consistency of code
			handling managed keys. [RT #46468]

4811.	[bug]		Revert api changes to use <isc/buffer.h> inline
			macros.  Provide a alternative mechanism to turn
			on the use of inline macros when building BIND.
			[RT #46520]

4810.	[test]		The chain system test failed if the IPv6 interfaces
			were not configured. [RT #46508]

	--- 9.12.0b2 released ---

4809.	[port]		Check at configure time whether -latomic is needed
			for stdatomic.h. [RT #46324]

4808.	[bug]		Properly test for zlib.h. [RT #46504]

4807.	[cleanup]	isc_rng_randombytes() returns a specified number of
			bytes from the PRNG; this is now used instead of
			calling isc_rng_random() multiple times. [RT #46230]

4806.	[func]		Log messages related to loading of zones are now
			directed to the "zoneload" logging category.
			[RT #41640]

4805.	[bug]		TCP4Active and TCP6Active weren't being updated
			correctly. [RT #46454]

4804.	[port]		win32: access() does not work on directories as
			required by POSIX.  Supply a alternative in
			isc_file_isdirwritable. [RT #46394]

4803.	[placeholder]

4802.	[test]		Refactor mkeys system test to make it quicker and more
			reliable. [RT #45293]

4801.	[func]		'dnssec-lookaside auto;' and 'dnssec-lookaside .
			trust-anchor dlv.isc.org;' now elicit warnings rather
			than being fatal configuration errors. [RT #46410]

4800.	[bug]		When processing delzone, write one zone config per
			line to the NZF. [RT #46323]

4799.	[cleanup]	Improve clarity of keytable unit tests. [RT #46407]

4798.	[func]		Keys specified in "managed-keys" statements
			are tagged as "initializing" until they have been
			updated by a key refresh query. If initialization
			fails it will be visible from "rndc secroots".
			[RT #46267]

4797.	[func]		Removed "isc-hmac-fixup", as the versions of BIND that
			had the bug it worked around are long past end of
			life. [RT #46411]

4796.	[bug]		Increase the maximum configurable TCP keepalive
			timeout to 65535. [RT #44710]

4795.	[func]		A new statistics counter has been added to track
			priming queries. [RT #46313]

4794.	[func]		"dnssec-checkds -s" specifies a file from which
			to read a DS set rather than querying the parent.
			[RT #44667]

4793.	[bug]		nsupdate -[46] could overflow the array of server
			addresses. [RT #46402]

4792.	[bug]		Fix map file header correctness check. [RT #38418]

4791.	[doc]		Fixed outdated documentation about export libraries.
			[RT #46341]

4790.	[bug]		nsupdate could trigger a require when sending a
			update to the second address of the server.
			[RT #45731]

4789.	[cleanup]	Check writability of new-zones-directory. [RT #46308]

4788.	[cleanup]	When using "update-policy local", log a warning
			when an update matching the session key is received
			from a remote host. [RT #46213]

4787.	[cleanup]	Turn nsec3param_salt_totext() into a public function,
			dns_nsec3param_salttotext(), and add unit tests for it.
			[RT #46289]

4786.	[func]		The "filter-aaaa-on-v4" and "filter-aaaa-on-v6"
			options are no longer conditionally compiled.
			[RT #46340]

4785.	[func]		The hmac-md5 algorithm is no longer recommended for
			use with RNDC keys.  The default in rndc-confgen
			is now hmac-sha256. [RT #42272]

4784.	[func]		The use of dnssec-keygen to generate HMAC keys is
			deprecated in favor of tsig-keygen.  dnssec-keygen
			will print a warning when used for this purpose.
			All HMAC algorithms will be removed from
			dnssec-keygen in a future release. [RT #42272]

4783.	[test]		dnssec: 'check that NOTIFY is sent at the end of
			NSEC3 chain generation failed' required more time
			on some machines for the IXFR to complete. [RT #46388]

4782.	[test]		dnssec: 'checking positive and negative validation
			with negative trust anchors' required more time to
			complete on some machines. [RT #46386]

4781.	[maint]		B.ROOT-SERVERS.NET is now 199.9.14.201. [RT #45889]

4780.	[bug]		When answering ANY queries, don't include the NS
			RRset in the authority section if it was already
			in the answer section. [RT #44543]

4779.	[bug]		Expire NTA at the start of the second. Don't update
			the expiry value if the record has already expired
			after a successful check. [RT #46368]

4778.	[test]		Improve synth-from-dnssec testing. [RT #46352]

4777.	[cleanup]	Removed a redundant call to configure_view_acl().
			[RT #46369]

4776.	[bug]		Improve portability of ht_test. [RT #46333]

4775.	[bug]		Address Coverity warnings in ht_test.c and mem_test.c
			[RT #46281]

4774.	[bug]		<isc/util.h> was incorrectly included in several
			header files. [RT #46311]

4773.	[doc]		Fixed generating Doxygen documentation for functions
			annotated using certain macros.  Miscellaneous
			Doxygen-related cleanups. [RT #46276]

	--- 9.12.0b1 released ---

4772.	[test]		Expanded unit testing framework for libns, using
			hooks to interrupt query flow and inspect state
			at specified locations. [RT #46173]

4771.	[bug]		When sending RFC 5011 refresh queries, disregard
			cached DNSKEY rrsets. [RT #46251]

4770.	[bug]		Cache additional data from priming queries as glue.
			Previously they were ignored as unsigned
			non-answer data from a secure zone, and never
			actually got added to the cache, causing hints
			to be used frequently for root-server
			addresses, which triggered re-priming. [RT #45241]

4769.	[func]		The working directory and managed-keys directory has
			to be writeable (and seekable). [RT #46077]

4768.	[func]		By default, memory is no longer filled with tag values
			when it is allocated or freed; this improves
			performance but makes debugging of certain memory
			issues more difficult. "named -M fill" turns memory
			filling back on. (Building "configure
			--enable-developer", turns memory fill on by
			default again; it can then be disabled with
			"named -M nofill".) [RT #45123]

4767.	[func]		Add a new function, isc_buffer_printf(), which can be
			used to append a formatted string to the used region of
			a buffer. [RT #46201]

4766.	[cleanup]	Addresss Coverity warnings. [RT #46150]

4765.	[bug]		Address potential INSIST in dnssec-cds. [RT #46150]

4764.	[bug]		Address portability issues in cds system test.
			[RT #46214]

4763.	[contrib]	Improve compatibility when building MySQL DLZ
			module by using mysql_config if available.
			[RT #45558]

4762.	[func]		"update-policy local" is now restricted to updates
			from local addresses. (Previously, other addresses
			were allowed so long as updates were signed by the
			local session key.) [RT #45492]

4761.	[protocol]	Add support for DOA. [RT #45612]

4760.	[func]		Add glue cache statistics counters. [RT #46028]

4759.	[func]		Add logging channel "trust-anchor-telementry" to
			record trust-anchor-telementry in incoming requests.
			Both _ta-XXXX.<anchor>/NULL and EDNS KEY-TAG options
			are logged.  [RT #46124]

4758.	[doc]		Remove documentation of unimplemented "topology".
			[RT #46161]

4757.	[func]		New "dnssec-cds" command creates a new parent DS
			RRset based on CDS or CDNSKEY RRsets found in
			a child zone, and generates either a dsset file
			or stream of nsupdate commands to update the
			parent. Thanks to Tony Finch. [RT #46090]

4756.	[bug]		Interrupting dig could lead to an INSIST failure after
			certain errors were encountered while querying a host
			whose name resolved to more than one address.  Change
			4537 increased the odds of triggering this issue by
			causing dig to hang indefinitely when certain error
			paths were evaluated.  dig now also retries TCP queries
			(once) if the server gracefully closes the connection
			before sending a response. [RT #42832, #45159]

4755.	[cleanup]	Silence unnecessary log message when NZF file doesn't
			exist. [RT #46186]

4754.	[bug]		dns_zone_setview needs a two stage commit to properly
			handle errors. [RT #45841]

4753.	[contrib]	Software obtainable from known upstream locations
			(i.e., zkt, nslint, query-loc) has been removed.
			Links to these and other packages can be found at
			https://www.isc.org/community/tools [RT #46182]

4752.	[test]		Add unit test for isc_net_pton. [RT #46171]

4751.	[func]		"dnssec-signzone -S" can now automatically add parent
			synchronization records (CDS and CDNSKEY) according
			to key metadata set using the -Psync and -Dsync
			options to dnssec-keygen and dnssec-settime.
			[RT #46149]

4750.	[func]		"rndc managed-keys destroy" shuts down RFC 5011 key
			maintenance and deletes the managed-keys database.
			If followed by "rndc reconfig" or a server restart,
			key maintenance is reinitialized from scratch.
			This is primarily intended for testing. [RT #32456]

4749.	[func]		The ISC DLV service has been shut down, and all
			DLV records have been removed from dlv.isc.org.
			- Removed references to ISC DLV in documentation
			- Removed DLV key from bind.keys
			- No longer use ISC DLV by default in delv
			- "dnssec-lookaside auto" and configuration of
			  "dnssec-lookaide" with dlv.isc.org as the trust
			  anchor are both now fatal errors.
			[RT #46155]

4748.	[cleanup]	Sprintf to snprintf coversions. [RT #46132]

4747.	[func]		Synthesis of responses from DNSSEC-verified records.
			Stage 3 - synthesize NODATA responses. [RT #40138]

4746.	[cleanup]	Add configured prefixes to configure summary
			output. [RT #46153]

4745.	[test]		Add color-coded pass/fail messages to system
			tests when running on terminals that support them.
			[RT #45977]

4744.	[bug]		Suppress trust-anchor-telementry queries if
			validation is disabled. [RT #46131]

4743.	[func]		Exclude trust-anchor-telementry queries from
			synth-from-dnssec processing. [RT #46123]

4742.	[func]		Synthesis of responses from DNSSEC-verified records.
			Stage 2 - synthesis of records from wildcard data.
			If the dns64 or filter-aaaa* is configured then the
			involved lookups are currently excluded. [RT #40138]

4741.	[bug]		Make isc_refcount_current() atomically read the
			counter value. [RT #46074]

4740.	[cleanup]	Avoid triggering format-truncated warnings. [RT #46107]

4739.	[cleanup]	Address clang static analysis warnings. [RT #45952]

4738.	[port]		win32: strftime mishandles %Z. [RT #46039]

4737.	[cleanup]	Address Coverity warnings. [RT #46012]

4736.	[cleanup]	(a) Added comments to NSEC3-related functions in
			lib/dns/zone.c.  (b) Refactored NSEC3 salt formatting
			code.  (c) Minor tweaks to lock and result handling.
			[RT #46053]

4735.	[bug]		Add @ISC_OPENSSL_LIBS@ to isc-config. [RT #46078]

4734.	[contrib]	Added sample configuration for DNS-over-TLS in
			contrib/dnspriv.

4733.	[bug]		Change #4706 introduced a bug causing TCP clients
			not be reused correctly, leading to unconstrained
			memory growth. [RT #46029]

4732.	[func]		Change default minimal-responses setting to
			no-auth-recursive. [RT #46016]

4731.	[bug]		Fix use after free when closing an LMDB. [RT #46000]

4730.	[bug]		Fix out of bounds access in DHCID totext() method.
			[RT #46001]

4729.	[bug]		Don't use memset() to wipe memory, as it may be
			removed by compiler optimizations when the
			memset() occurs on automatic stack allocation
			just before function return. [RT #45947]

4728.	[func]		Use C11's stdatomic.h instead of isc_atomic
			where available. [RT #40668]

4727.	[bug]		Retransferring an inline-signed slave using NSEC3
			around the time its NSEC3 salt was changed could result
			in an infinite signing loop. [RT #45080]

4726.	[port]		Prevent setsockopt() errors related to TCP_FASTOPEN
			from being logged on FreeBSD if the kernel does not
			support it.  Notify the user when the kernel does
			support TCP_FASTOPEN, but it is disabled by sysctl.
			Add a new configure option, --disable-tcp-fastopen, to
			disable use of TCP_FASTOPEN altogether. [RT #44754]

4725.	[bug]		Nsupdate: "recvsoa" was incorrectly reported for
			failures in sending the update message.  The correct
			location to be reported is "update_completed".
			[RT #46014]

4724.	[func]		By default, BIND now uses the random number
			functions provided by the crypto library (i.e.,
			OpenSSL or a PKCS#11 provider) as a source of
			randomness rather than /dev/random.  This is
			suitable for virtual machine environments
			which have limited entropy pools and lack
			hardware random number generators.

			This can be overridden by specifying another
			entropy source via the "random-device" option
			in named.conf, or via the -r command line option;
			however, for functions requiring full cryptographic
			strength, such as DNSSEC key generation, this
			cannot be overridden. In particular, the -r
			command line option no longer has any effect on
			dnssec-keygen.

			This can be disabled by building with
			"configure --disable-crypto-rand".
			[RT #31459] [RT #46047]

4723.	[bug]		Statistics counter DNSTAPdropped was misidentified
			as DNSSECdropped. [RT #46002]

4722.	[cleanup]	Clean up uses of strcpy() and strcat() in favor of
			strlcpy() and strlcat() for safety. [RT #45981]

4721.	[func]		'dnssec-signzone -x' and 'dnssec-dnskey-kskonly'
			options now apply to CDNSKEY and DS records as well
			as DNSKEY. Thanks to Tony Finch. [RT #45689]

4720.	[func]		Added a statistics counter to track prefetch
			queries. [RT #45847]

4719.	[bug]		Address PVS static analyzer warnings. [RT #45946]

4718.	[func]		Avoid seaching for a owner name compression pointer
			more than once when writing out a RRset. [RT #45802]

4717.	[bug]		Treat replies with QCOUNT=0 as truncated if TC=1,
			FORMERR if TC=0, and log the error correctly.
			[RT #45836]

4716.	[placeholder]

	--- 9.12.0a1 released ---

4715.	[bug]		TreeMemMax was mis-identified as a second HeapMemMax
			in the Json cache statistics. [RT #45980]

4714.	[port]		openbsd/libressl: add support for building with
			--enable-openssl-hash. [RT #45982]

4713.	[func]		Added support for the DNS Response Policy Service
			(DNSRPS) API, which allows named to use an external
			response policy daemon when built with
			"configure --enable-dnsrps". Thanks to Farsight
			Security. [RT #43376]

4712.	[bug]		"dig +domain" and "dig +search" didn't retain the
			search domain when retrying with TCP. [RT #45547]

4711.	[test]		Some RR types were missing from genzones.sh.
			[RT #45782]

4710.	[cleanup]	Changed the --enable-openssl-hash default to yes.
			[RT #45019]

4709.	[cleanup]	Use dns_name_fullhash() to hash names for RRL.
			[RT #45435]

4708.	[cleanup]	Legacy Windows builds (i.e. for XP and earlier)
			are no longer supported. [RT #45186]

4707.	[func]		The lightweight resolver daemon and library (lwresd
			and liblwres) have been removed. [RT #45186]

4706.	[func]		Code implementing name server query processing has
			been moved from bin/named to a new library "libns".
			Functions remaining in bin/named are now prefixed
			with "named_" rather than "ns_".  This will make it
			easier to write unit tests for name server code, or
			link name server functionality into new tools.
			[RT #45186]

4705.	[placeholder]

4704.	[cleanup]	Silence Visual Studio compiler warnings. [RT #45898]

4703.	[bug]		BINDInstall.exe was missing some buffer length checks.
			[RT #45898]

4702.	[func]		Update function declarations to use
			dns_masterstyle_flags_t for style flags. [RT #45924]

4701.	[cleanup]	Refactored lib/dns/tsig.c to reduce code
			duplication and simplify the disabling of MD5.
			[RT #45490]

4700.	[func]		Serving of stale answers is now supported. This
			allows named to provide stale cached answers when
			the authoritative server is under attack.
			See max-stale-ttl, stale-answer-enable,
			stale-answer-ttl. [RT #44790]

4699.	[func]		Multiple cookie-secret clauses can now be specified.
			The first one specified is used to generate new
			server cookies.  [RT #45672]

4698.	[port]		Add --with-python-install-dir configure option to allow
			specifying a nonstandard installation directory for
			Python modules. [RT #45407]

4697.	[bug]		Restore workaround for Microsoft Windows TSIG hash
			computation bug. [RT #45854]

4696.	[port]		Enable filter-aaaa support by default on Windows
			builds. [RT #45883]

4695.	[bug]		cookie-secrets were not being properly checked by
			named-checkconf. [RT #45886]

4694.	[func]		dnssec-keygen no longer uses RSASHA1 by default;
			the signing algorithm must be specified on
			the command line with the "-a" option.  Signing
			scripts that rely on the existing default behavior
			will break; use "dnssec-keygen -a RSASHA1" to
			repair them. (The goal of this change is to make
			it easier to find scripts using RSASHA1 so they
			can be changed in the event of that algorithm
			being deprecated in the future.) [RT #44755]

4693.	[func]		Synthesis of responses from DNSSEC-verified records.
			Stage 1 covers NXDOMAIN synthesis from NSEC records.
			This is controlled by synth-from-dnssec and is enabled
			by default. [RT #40138]

4692.	[bug]		Fix build failures with libressl introduced in 4676.
			[RT #45879]

4691.	[func]		Add -4/-6 command line options to nsupdate and rndc.
			[RT #45632]

4690.	[bug]		Command line options -4/-6 were handled inconsistently
			between tools. [RT #45632]

4689.	[cleanup]	Turn on minimal responses for CDNSKEY and CDS in
			addition to DNSKEY and DS. Thanks to Tony Finch.
			[RT #45690]

4688.	[protocol]	Check and display EDNS KEY TAG options (RFC 8145) in
			messages. [RT #44804]

4687.	[func]		Refactor tracklines code. [RT #45126]

4686.	[bug]		dnssec-settime -p could print a bogus warning about
			key deletion scheduled before its inactivation when a
			key had an inactivation date set but no deletion date
			set. [RT #45807]

4685.	[bug]		dnssec-settime incorrectly calculated publication and
			activation dates for a successor key. [RT #45806]

4684.	[bug]		delv could send bogus DNS queries when an explicit
			server address was specified on the command line along
			with -4/-6. [RT #45804]

4683.	[bug]		Prevent nsupdate from immediately exiting on invalid
			user input in interactive mode. [RT #28194]

4682.	[bug]		Don't report errors on records below a DNAME.
			[RT #44880]

4681.	[bug]		Log messages from the validator now include the
			associated view unless the view is "_default/IN"
			or "_dnsclient/IN". [RT #45770]

4680.	[bug]		Fix failing over to another master server address when
			nsupdate is used with GSS-API. [RT #45380]

4679.	[cleanup]	Suggest using -o when dnssec-verify finds a SOA record
			not at top of zone and -o is not used. [RT #45519]

4678.	[bug]		geoip-use-ecs has the wrong type when geoip support
			is disabled at configure time. [RT #45763]

4677.	[cleanup]	Split up the main function in dig to better support
			the iOS app version. [RT #45508]

4676.	[cleanup]	Allow BIND to be built using OpenSSL 1.0.X with
			deprecated functions removed. [RT #45706]

4675.	[cleanup]	Don't use C++ keyword class. [RT #45726]

4674.	[func]		"dig +sigchase", and related options "+topdown" and
			"+trusted-keys", have been removed. Use "delv" for
			queries with DNSSEC validation. [RT #42793]

4673.	[port]		Silence GCC 7 warnings. [RT #45592]

4672.	[placeholder]

4671.	[bug]		Fix a race condition that could cause the
			resolver to crash with assertion failure when
			chasing DS in specific conditions with a very
			short RTT to the upstream nameserver. [RT #45168]

4670.	[cleanup]	Ensure that a request MAC is never sent back
			in an XFR response unless the signature was
			verified. [RT #45494]

4669.	[func]		Iterative query logic in resolver.c has been
			refactored into smaller functions and commented,
			for improved readability, maintainability and
			testability. [RT #45362]

4668.	[bug]		Use localtime_r and gmtime_r for thread safety.
			[RT #45664]

4667.	[cleanup]	Refactor RDATA unit tests. [RT #45610]

4666.	[bug]		dnssec-keymgr: Domain names beginning with digits (0-9)
			could cause a parser error when reading the policy
			file. This now works correctly so long as the domain
			name is quoted. [RT #45641]

4665.	[protocol]	Added support for ED25519 and ED448 DNSSEC signing
			algorithms (RFC 8080). (Note: these algorithms
			depend on code currently in the development branch
			of OpenSSL which has not yet been released.)
			[RT #44696]

4664.	[func]		Add a "glue-cache" option to enable or disable the
			glue cache. The default is "yes". [RT #45125]

4663.	[cleanup]	Clarify error message printed by dnssec-dsfromkey.
			[RT #21731]

4662.	[performance]	Improve cache memory cleanup of zero TTL records
			by putting them at the tail of LRU header lists.
			[RT #45274]

4661.	[bug]		A race condition could occur if a zone was reloaded
			while resigning, triggering a crash in
			rbtdb.c:closeversion(). [RT #45276]

4660.	[bug]		Remove spurious "peer" from Windows socket log
			messages. [RT #45617]

4659.	[bug]		Remove spurious log message about lmdb-mapsize
			not being supported when parsing builtin
			configuration file. [RT #45618]

4658.	[bug]		Clean up build directory created by "setup.py install"
			immediately.  [RT #45628]

			zone's "default-masters" option to the generated
			configuration of its member zones. [RT #45545]

4655.	[bug]		Lack of seccomp could be falsely reported. [RT #45599]

4654.	[cleanup]	Don't use C++ keywords delete, new and namespace.
			[RT #45538]

4653.	[bug]		Reorder includes to move @DST_OPENSSL_INC@ and
			@ISC_OPENSSL_INC@ after shipped include directories.
			[RT #45581]

4652.	[bug]		Nsupdate could attempt to use a zeroed address on
			server timeout. [RT #45417]
