Import 9.16.33; last imported was 9.16.20

	--- 9.16.33 released ---

5962.	[security]	Fix memory leak in EdDSA verify processing.
			(CVE-2022-38178) [GL #3487]

5961.	[security]	Fix memory leak in ECDSA verify processing.
			(CVE-2022-38177) [GL #3487]

5960.	[security]	Fix serve-stale crash that could happen when
			stale-answer-client-timeout was set to 0 and there was
			a stale CNAME in the cache for an incoming query.
			(CVE-2022-3080) [GL #3517]

5957.	[security]	Prevent excessive resource use while processing large
			delegations. (CVE-2022-2795) [GL #3394]

5956.	[func]		Make RRL code treat all QNAMEs that are subject to
			wildcard processing within a given zone as the same
			name. [GL #3459]

5955.	[port]		The libxml2 library has deprecated the usage of
			xmlInitThreads() and xmlCleanupThreads() functions. Use
			xmlInitParser() and xmlCleanupParser() instead.
			[GL #3518]

5954.	[func]		Fallback to IDNA2003 processing in dig when IDNA2008
			conversion fails. [GL #3485]

5953.	[bug]		Fix a crash on shutdown in delete_trace_entry(). Add
			mctx attach/detach pair to make sure that the memory
			context used by a memory pool is not destroyed before
			the memory pool itself. [GL #3515]

5952.	[bug]		Use quotes around address strings in YAML output.
			[GL #3511]

5951.	[bug]		In some cases, the dnstap query_message field was
			erroneously set when logging response messages.
			[GL #3501]

5948.	[bug]		Fix nsec3.c:dns_nsec3_activex() function, add a missing
			dns_db_detachnode() call. [GL #3500]

5945.	[bug]		If parsing /etc/bind.key failed, delv could assert
			when trying to parse the built in trust anchors as
			the parser hadn't been reset. [GL !6468]

5942.	[bug]		Fix tkey.c:buildquery() function's error handling by
			adding the missing cleanup code. [GL #3492]

5941.	[func]		Zones with dnssec-policy now require dynamic DNS or
			inline-siging to be configured explicitly. [GL #3381]

5936.	[bug]		Don't enable serve-stale for lookups that error because
			it is a duplicate query or a query that would be
			dropped. [GL #2982]

	--- 9.16.32 released ---

5934.	[func]		Improve fetches-per-zone fetch limit logging to log
			the final allowed and spilled values of the fetch
			counters before the counter object gets destroyed.
			[GL #3461]

5933.	[port]		Automatically disable RSASHA1 and NSEC3RSASHA1 in
			named on Fedorda 33, Oracle Linux 9 and RHEL9 when
			they are disabled by the security policy. [GL #3469]

5932.	[bug]		Fix rndc dumpdb -expired and always include expired
			RRsets, not just for RBTDB_VIRTUAL time window.
			[GL #3462]

5929.	[bug]		The "max-zone-ttl" option in "dnssec-policy" was
			not fully effective; it was used for timing key
			rollovers but did not actually place an upper limit
			on TTLs when loading a zone. This has been
			corrected, and the documentation has been clarified
			to indicate that the old "max-zone-ttl" zone option
			is now ignored when "dnssec-policy" is in use.
			[GL #2918]

5924.	[func]		When it's necessary to use AXFR to respond to an
			IXFR request, a message explaining the reason
			is now logged at level info. [GL #2683]

5923.	[bug]		Fix inheritance for dnssec-policy when checking for
			inline-signing. [GL #3438]

5922.	[bug]		Forwarding of UPDATE message could fail with the
			introduction of netmgr. This has been fixed. [GL #3389]

	--- 9.16.31 released ---

5917.	[bug]		Update ifconfig.sh script as is miscomputed interface
			identifiers when destroying interfaces. [GL #3061]

5915.	[bug]		Detect missing closing brace (}) and computational
			overflows in $GENERATE directives. [GL #3429]

5913.	[bug]		Fix a race between resolver query timeout and
			validation in resolver.c:validated(). Remove
			resolver.c:maybe_destroy() as it is no loger needed.
			[GL #3398]

5909.	[bug]		The server-side destination port was missing from dnstap
			captures of client traffic. [GL #3309]

5905.	[bug]		When the TCP connection would be closed/reset between
			the connect/accept and the read, the uv_read_start()
			return value would be unexpected and cause an assertion
			failure. [GL #3400]

5903.	[bug]		When named checks that the OPCODE in a response matches
			that of the request, if there is a mismatch named logs
			an error.  Some of those error messages incorrectly
			used RCODE instead of OPCODE to lookup the nemonic.
			This has been corrected. [GL !6420]

	--- 9.16.30 released ---

5899.	[func]		Don't try to process DNSSEC-related and ZONEMD records
			in catz. [GL #3380]

5890.	[bug]		When the fetches-per-server quota was adjusted
			because of an authoritative server timing out more
			or less frequently, it was incorrectly set to 1
			rather than the intended value.  This has been
			fixed. [GL #3327]

5888.	[bug]		Only write key files if the dnssec-policy keymgr has
			changed the metadata. [GL #3302]

5823.	[func]		Replace hazard pointers based lock-free list with
			locked-list based queue that's simpler and has no or
			little performance impact. [GL #3180]

	--- 9.16.29 released ---

5885.	[bug]		RPZ NSIP and NSDNAME rule processing didn't handle stub
			and static-stub zones at or above the query name.  This
			has now been addressed. [GL #3232]

5881.	[bug]		dig +nssearch could hang in rare cases when recv_done()
			callback was being called earlier than send_done().
			[GL #3278]

5880.	[func]		Add new named command-line option -C to print built-in
			defaults. [GL #1326]

5879.	[contrib]	dlz: Add FALLTHROUGH and UNREACHABLE macros. [GL #3306]

5874.	[bug]		keymgr didn't work with python 3.11. [GL !6157]

5866.	[bug]		Work around a jemalloc quirk which could trigger an
			out-of-memory condition in named over time. [GL #3287]

5863.	[bug]		If there was a pending negative cache DS entry,
			validations depending upon it could fail. [GL #3279]

5858.	[bug]		Don't remove CDS/CDNSKEY DELETE records on zone sign
			when using 'auto-dnssec maintain;'. [GL #2931]

	--- 9.16.28 released ---

5856.	[bug]		The "starting maxtime timer" message related to outgoing
			zone transfers was incorrectly logged at the ERROR level
			instead of DEBUG(1). [GL #3208]

5852.	[func]		Add new "reuseport" option to enable/disable load
			balancing of sockets. [GL #3249]

5843.	[bug]		When an UPDATE targets a zone that is not configured,
			the requested zone name is now logged in the "not
			authoritative" error message, so that it is easier to
			track down problematic update clients. [GL #3209]

5836.	[bug]		Quote the dns64 prefix in error messages that complain
			about problems with it, to avoid confusion with the
			following dns64 ACLs. [GL #3210]

5834.	[cleanup]	C99 variable-length arrays are difficult to use safely,
			so avoid them except in test code. [GL #3201]

5828.	[bug]		Replace single TCP write timer with per-TCP write
			timers. [GL #3200]

5824.	[bug]		Invalid dnssec-policy definitions were being accepted
			where the defined keys did not cover both KSK and ZSK
			roles for a given algorithm.  This is now checked for
			and the dnssec-policy is rejected if both roles are
			not present for all algorithms in use. [GL #3142]

	--- 9.16.27 released ---

5818.	[security]	A synchronous call to closehandle_cb() caused
			isc__nm_process_sock_buffer() to be called recursively,
			which in turn left TCP connections hanging in the
			CLOSE_WAIT state blocking indefinitely when
			out-of-order processing was disabled. (CVE-2022-0396)
			[GL #3112]

5817.	[security]	The rules for acceptance of records into the cache
			have been tightened to prevent the possibility of
			poisoning if forwarders send records outside
			the configured bailiwick. (CVE-2021-25220) [GL #2950]

5816.	[bug]		Make BIND compile with LibreSSL 3.5.0, as it was using
			not very accurate pre-processor checks for using shims.
			[GL #3172]

5815.	[bug]		If an oversized key name of a specific length was used
			in the text form of an HTTP or SVBC record, an INSIST
			could be triggered when parsing it. [GL #3175]

5814.	[bug]		The RecursClients statistics counter could underflow
			in certain resolution scenarios. [GL #3147]

5811.	[bug]		Reimplement the maximum and idle timeouts for outgoing
			zone transfers. [GL #1897]

5807.	[bug]		Add a TCP "write" timer, and time out writing
			connections after the "tcp-idle-timeout" period
			has elapsed. [GL #3132]

5804.	[func]		Add a debug log message when starting and ending
			the task exclusive mode. [GL #3137]

	--- 9.16.26 released ---

5801.	[bug]		Log "quota reached" message when hard quota
			is reached when accepting a connection. [GL #3125]

5800.	[func]		Add ECS support to the DLZ interface. [GL #3082]

5797.	[bug]		A failed view configuration during a named
			reconfiguration procedure could cause inconsistencies
			in BIND internal structures, causing a crash or other
			unexpected errors. [GL #3060]

5795.	[bug]		rndc could crash when interrupted by a signal
			before receiving a response. [GL #3080]

5793.	[bug]		Correctly detect and enable UDP recvmmsg support
			in all versions of libuv that support it. [GL #3095]

	--- 9.16.25 released ---

5789.	[bug]		Allow replacing expired zone signatures with
			signatures created by the KSK. [GL #3049]

5788.	[bug]		An assertion could occur if a catalog zone event was
			scheduled while the task manager was being shut
			down. [GL #3074]

5787.	[doc]		Update 'auto-dnssec' documentation, it may only be
			activated at zone level. [GL #3023]

5786.	[bug]		Defer detaching from zone->raw in zone_shutdown() if
			the zone is in the process of being dumped to disk, to
			ensure that the unsigned serial number information is
			always written in the raw-format header of the signed
			version on an inline-signed zone. [GL #3071]

5785.	[bug]		named could leak memory when two dnssec-policy clauses
			had the same name. named failed to log this error.
			[GL #3085]

5776.	[bug]		Add a missing isc_condition_destroy() for nmsocket
			condition variable and add missing isc_mutex_destroy()
			for nmworker lock. [GL #3051]

5676.	[func]		Memory use in named was excessive. This has been
			addressed by:
			- Replacing locked memory pools with normal memory
			  allocations.
			- Reducing the number of retained free items in
			  unlocked memory pools.
			- Disabling the internal allocator by default.
			  "named -M internal" turns it back on.
			[GL #2398]

	--- 9.16.24 released ---

5773.	[func]		Change the message when accepting TCP connection has
			failed to say "Accepting TCP connection failed" and
			change the log level for ISC_R_NOTCONNECTED, ISC_R_QUOTA
			and ISC_R_SOFTQUOTA results codes from ERROR to INFO.
			[GL #2700]

5768.	[bug]		dnssec-dsfromkey failed to omit revoked keys. [GL #853]

5764.	[bug]		dns_sdlz_putrr failed to process some valid resource
			records. [GL #3021]

5762.	[bug]		Fix a "named" crash related to removing and restoring a
			`catalog-zone` entry in the configuration file and
			running `rndc reconfig`. [GL #1608]

5758.	[bug]		mdig now honors the operating system's preferred
			ephemeral port range. [GL #2374]

5757.	[test]		Replace sed in nsupdate system test with awk to
			construct the nsupdate command.  The sed expression
			was not reliably changing the ttl. [GL #3003]

	--- 9.16.23 released ---

5752.	[bug]		Fix an assertion failure caused by missing member zones
			during a reload of a catalog zone. [GL #2308]

5750.	[bug]		Fix a bug when comparing two RSA keys. There was a typo
			which caused the "p" prime factors to not being
			compared. [GL #2972]

5737.	[bug]		Address Coverity warning in lib/dns/dnssec.c.
			[GL #2935]

	--- 9.16.22 released ---

5736.	[security]	The "lame-ttl" option is now forcibly set to 0. This
			effectively disables the lame server cache, as it could
			previously be abused by an attacker to significantly
			degrade resolver performance. (CVE-2021-25219)
			[GL #2899]

5724.	[bug]		Address a potential deadlock when checking zone content
			consistency. [GL #2908]

5723.	[bug]		Change 5709 broke backward compatibility for the
			"check-names master ..." and "check-names slave ..."
			options. This has been fixed. [GL #2911]

5720.	[contrib]	Old-style DLZ drivers that had to be enabled at
			build-time have been marked as deprecated. [GL #2814]

5719.	[func]		The "map" zone file format has been marked as
			deprecated. [GL #2882]

5717.	[func]		The "cache-file" option, which was documented as "for
			testing purposes only" and not to be used, has been
			removed. [GL #2903]

5716.	[bug]		Multiple library names were mistakenly passed to the
			krb5-config utility when ./configure was invoked with
			the --with-gssapi=[/path/to/]krb5-config option. This
			has been fixed by invoking krb5-config separately for
			each required library. [GL #2866]

5715.	[func]		Add a check for ports specified in "*-source(-v6)"
			options clashing with a global listening port. Such a
			configuration was already unsupported, but it failed
			silently; it is now treated as an error. [GL #2888]

5714.	[bug]		Remove the "adjust interface" mechanism which was
			responsible for setting up listeners on interfaces when
			the "*-source(-v6)" address and port were the same as
			the "listen-on(-v6)" address and port. Such a
			configuration is no longer supported; under certain
			timing conditions, that mechanism could prevent named
			from listening on some TCP ports. This has been fixed.
			[GL #2852]

5712.	[doc]		Add deprecation notice about removing native PKCS#11
			support in the next major BIND 9 release. [GL #2691]

	--- 9.16.21 released ---

5711.	[bug]		"map" files exceeding 2GB in size failed to load due to
			a size comparison that incorrectly treated the file size
			as a signed integer. [GL #2878]

5710.	[port]		win32: incorrect parentheses resulted in the wrong
			sizeof() tests being used to pick the appropriate
			Windows atomic operations for the object's size.
			[GL #2891]

5709.	[cleanup]	Enum values throughout the code have been updated
			to use the terms "primary" and "secondary" instead of
			"master" and "slave", respectively. [GL #1944]

5708.	[bug]		The thread-local isc_tid_v variable was not properly
			initialized when running BIND 9 as a Windows Service,
			leading to a crash on startup. [GL #2837]

5705.	[bug]		Change #5686 altered the internal memory structure of
			zone databases, but neglected to update the MAPAPI value
			for zone files in "map" format. This caused named to
			attempt to load incompatible map files, triggering an
			assertion failure on startup. The MAPAPI value has now
			been updated, so named rejects outdated files when
			encountering them. [GL #2872]

5704.	[bug]		Change #5317 caused the EDNS TCP Keepalive option to be
			ignored inadvertently in client requests. It has now
			been fixed and this option is handled properly again.
			[GL #1927]

5701.	[bug]		named-checkconf failed to detect syntactically invalid
			values of the "key" and "tls" parameters used to define
			members of remote server lists. [GL #2461]

5700.	[bug]		When a member zone was removed from a catalog zone,
			journal files for the former were not deleted.
			[GL #2842]

5699.	[func]		Data structures holding DNSSEC signing statistics are
			now grown and shrunk as necessary upon key rollover
			events. [GL #1721]

5698.	[bug]		When a DNSSEC-signed zone which only has a single
			signing key available is migrated to use KASP, that key
			is now treated as a Combined Signing Key (CSK).
			[GL #2857]

5696.	[protocol]	Support for HTTPS and SVCB record types has been added.
			(This does not include ADDITIONAL section processing for
			these record types, only basic support for RR type
			parsing and printing.) [GL #1132]

5694.	[bug]		Stale data in the cache could cause named to send
			non-minimized queries despite QNAME minimization being
			enabled. [GL #2665]

5691.	[bug]		When a dynamic zone was made available in another view
			using the "in-view" statement, running "rndc freeze"
			always reported an "already frozen" error even though
			the zone was successfully frozen. [GL #2844]

5690.	[func]		dnssec-signzone now honors Predecessor and Successor
			metadata found in private key files: if a signature for
			an RRset generated by the inactive predecessor exists
			and does not need to be replaced, no additional
			signature is now created for that RRset using the
			successor key. This enables dnssec-signzone to gradually
			replace RRSIGs during a ZSK rollover. [GL #1551]
