This has been fixed. ISC would like to thank Vlatko Kosturjak from Marlink Cyber for bringing this vulnerability to our attention. [GL #5616] Feature Changes# Support compilation with cmocka 2.0.0+ bb9234c6ce The assert_in_range() function was deprecated in favor of assert_int_in_range() and assert_uint_in_range(). Add compatibility shims for cmocka<2.0.0 and use the new functions. [GL #5699] [GL !11437] Add more information to the rndc recursing output about fetches. 9766feb4df This adds more information about the active fetches for debugging and diagnostic purposes. [GL !11358] Bug Fixes# Make key rollovers more robust. 7a70d05b5d A manual rollover when the zone is in an invalid DNSSEC state causes predecessor keys to be removed too quickly. Additional safeguards to prevent this have been added. DNSSEC records will not be removed from the zone until the underlying state machine has moved back into a valid DNSSEC state. [GL #5458] [GL !11329] Fix a catalog zones issue when a member zone could fail to load. 95cbc2c327 A catalog zone's member zone could fail to load in some rare cases, when the internally generated zone configuration string was exceeding 512 bytes. That condition only was not enough for the issue to arise, but it was a necessary condition. This could happen, for example, if the catalog zone's default primary servers list contained a large number of items. This has been fixed. [GL #5658] [GL !11349] Allow glue in delegations with QTYPE=ANY. 441158ac18 When a query for type ANY triggered a delegation response, all additional data was omitted from the response, including mandatory glue. This has been corrected. [GL #5659] [GL !11283] Adding NSEC3 opt-out records could leave invalid records in chain. 1b90296e1f When creating an NSEC3 opt-out chain, a node in the chain could be removed too soon, causing the previous NSEC3 being unable to be found, resulting in invalid NSEC3 records to be left in the zone. This has been fixed. [GL #5671] [GL !11340] Fix slow speed of NSEC3 optout large delegation zone signing. 88f915b77b BIND 9.20 takes much more time signing a large delegation zone with NSEC3 optout compared to version 9.18. This has been restored. [GL #5672] [GL !11362] Reconfigure NSEC3 opt-out zone to NSEC causes zone to be invalid. 1d0e19c612 A zone that is signed with NSEC3, opt-out enabled, and then reconfigured to use NSEC, causes the zone to be published with missing NSEC records. This has been fixed. [GL #5679] [GL !11401] Fix a possible catalog zone issue during reconfiguration. 911b45b2b3 The named process could terminate unexpectedly during reconfiguration when a catalog zone update was taking place at the same time. This has been fixed. [GL !11386] Fix the charts in the statistics channel. 7c7b01dd65 The charts in the statistics channel could sometimes fail to render in the browser, and were completely disabled for Mozilla-based browsers for historical reasons. This has been fixed. [GL !11364] BIND 9.20.17# New Features# Add spatch to detect implicit bool/int/result cast. 02be363d1f Detection of implicit cast from a boolean into an int, or an isc_result_t into a boolean (either in an assignement or return position). If such pattern is found, a warning comment is added into the code (and the CI will fails) so the error can be spotted and manually fixed. [GL !11237] Feature Changes# Use atomics for CMM_{LOAD,STORE}_SHARED with ThreadSanitizer. 94fa721705 Upstream has removed the atomics implementation of CMM_LOAD_SHARED and CMM_STORE_SHARED as these can be used also with non-stdatomics types. As we only use the CMM api with stdatomics types, we can restore the previous behaviour to prevent ThreadSanitizer warnings. [GL #5660] [GL !11290] Provide more information when the memory allocation fails. 6749725610 Provide more information about the failure when the memory allocation fails. [GL !11304] Reduce the number of outgoing queries. 457b470e96 Reduces the number of outgoing queries when resolving the nameservers for delegation points. This helps the DNS resolver with cold cache resolve client queries with complex delegation chains and redirections. [GL !11258] Bug Fixes# Fix the spurious timeouts while resolving names. d96cf874fb Sometimes the loops in the resolving (e.g. to resolve or validate ns1.example.com we need to resolve ns1.example.com) were not properly detected leading to spurious 10 seconds delay. This has been fixed and such loops are properly detected. [GL #3033], #5578 [GL !11298] Fix bug where zone switches from NSEC3 to NSEC after retransfer. 3b40ffbf83 When a zone is re-transferred, but the zone journal on an inline-signing secondary is out of sync, the zone could fall back to using NSEC records instead of NSEC3. This has been fixed. [GL #5527] [GL !11274] Attach socket before async streamdns_resume_processing. bb9451c73f Call to streamdns_resume_processing is asynchronous but the socket passed as argument is not attached when scheduling the call. While there is no reproducible way (so far) to make the socket reference number down to 0 before streamdns_resume_processing is called, attach the socket before scheduling the call. This guard against an hypothetic case where, for some reasons, the socket refcount would reach 0, and be freed from memory when streamdns_resume_processing is called. [GL #5620] [GL !11260] AMTRELAY type 0 presentation format handling was wrong. adf104a063 RFC 8777 specifies a placeholder value of "." for the gateway field when the gateway type is 0 (no gateway). This was not being checked for nor emitted when displaying the record. This has been corrected. Instances of this record will need the placeholder period added to them when upgrading. [GL #5639] [GL !11255] Fix parsing bug in remote-servers with key or tls. d9400c5967 The remote-servers clause enable the following pattern using a named server-list: remote-servers a { 1.2.3.4; ... }; remote-servers b { a key foo; }; However, such configuration was wrongly rejected, with an "unexpected token 'foo'" error. Such configuration is now accepted. [GL #5646] [GL !11300] Fix TLS contexts cache object usage bug in the resolver. 13adf94006 named could terminate unexpectedly when reconfiguring or reloading, and if client-side TLS transport was in use (for example, when forwarding queries to a DoT server). This has been fixed. [GL #5653] [GL !11299] Fix unitiailized pointer check on getipandkeylist. 5ed0cf091b Function named_config_getipandkeylist could, in case of error in the early code attempting to get the port or tls-port, make a pointer check on a non-initialized value. This is now fixed. [GL !11306] Standardize CHECK and RETERR macros. ef714e91ac previously, there were over 40 separate definitions of CHECK macros, of which most used "goto cleanup", and the rest "goto failure" or "goto out". there were another 10 definitions of RETERR, of which most were identical to CHECK, but some simply returned a result code instead of jumping to a cleanup label. this has now been standardized throughout the code base: RETERR is for returning an error code in the case of an error, and CHECK is for jumping to a cleanup tag, which is now always called "cleanup". both macros are defined in isc/util.h. [GL !11069] Adding NSEC3 opt-out records could leave invalid records in chain. 1d83a8ad46 When creating an NSEC3 opt-out chain, a node in the chain could be removed too soon, causing the previous NSEC3 being unable to be found, resulting in invalid NSEC3 records to be left in the zone. This has been fixed. Closes [#5671](#5671) BIND 9.20.16# Feature Changes# Fix assertion failure from arc4random_uniform with invalid limit. 1040282de7e When the arc4random_uniform() is called on NetBSD with upper_bound that makes no sense statistically (0 or 1), the call crashes the calling program. Fix this by returning 0 when upper bound is < 2 as does Linux, FreeBSD and NetBSD. (Hint: System CSPRNG should never crash.) [GL #5596] [GL !11151] Bug Fixes# Fix dnssec-keygen key collision checking for KEY rrtype keys. ac8b23b80bf The dnssec-keygen utility program failed to detect possible Key ID collisions with the existing keys generated using the non-default -T KEY option (e.g. for SIG(0)). This has been fixed. [GL #5506] [GL !11128] Fix shutdown INSIST in dns_dispatchmgr_getblackhole. f0aaaef166c Previously, named could trigger an assertion in dns_dispatchmgr_getblackhole while shutting down. This has been fixed. [GL #5525] [GL !11162] Dnssec-verify now uses exit code 1 when failing due to illegal options. 6ead0aa4a2b Previously, dnssec-verify exited with code 0 if the options could not be parsed. This has been fixed. [GL #5574] [GL !11129] Prevent assertion failures of dig when server is specified before the -b option. deada63e2b2 Previously, dig could exit with an assertion failure when the server was specified before the dig -b option. This has been fixed. [GL #5609] [GL !11204] Skip unsupported algorithms when looking for signing key. c346fe88a1b A mix of supported and unsupported DNSSEC algorithms in the same zone could have caused validation failures. Ignore the DNSSEC keys with unsupported algorithm when looking for the signing keys. [GL #5622] [GL !11210] Fix configuration bugs involving global defaults. a85d6fb581c The configuration code for the max-cache-size, dnssec-validation, and response-padding options were unnecessarily complicated, and in the case of max-cache-size, buggy. These have been fixed. The optionmaps variable in configure_view() is no longer needed and has been removed. [GL !11172] Skip buffer allocations if not logging. 4f601175bd0 Currently, during IXFR we allocate a 2KB buffer for IXFR change logging regardless of the log level. This commit introduces an early check on the log level in dns_diff_print to avoid this. Results in a speedup from 28% in the test case from issue #5442. [GL !11192] BIND 9.20.15# Security Fixes# [CVE-2025-8677] DNSSEC validation fails if matching but invalid DNSKEY is found. 0d676bf9f23 Previously, if a matching but cryptographically invalid key was encountered during DNSSEC validation, the key was skipped and not counted towards validation failures. named now treats such DNSSEC keys as hard failures and the DNSSEC validation fails immediately, instead of continuing with the next DNSKEYs in the RRset. ISC would like to thank Zuyao Xu and Xiang Li from the All-in-One Security and Privacy Laboratory at Nankai University for bringing this vulnerability to our attention. [GL #5343] [CVE-2025-40778] Address various spoofing attacks. 23de94fd236 Previously, several issues could be exploited to poison a DNS cache with spoofed records for zones which were not DNSSEC-signed or if the resolver was configured to not do DNSSEC validation. These issues were assigned CVE-2025-40778 and have now been fixed. As an additional layer of protection, named no longer accepts DNAME records or extraneous NS records in the AUTHORITY section unless these are received via spoofing-resistant transport (TCP, UDP with DNS cookies, TSIG, or SIG(0)). ISC would like to thank Yuxiao Wu, Yunyi Zhang, Baojun Liu, and Haixin Duan from Tsinghua University for bringing this vulnerability to our attention. [GL #5414] [CVE-2025-40780] Cache-poisoning due to weak pseudo-random number generator. 34af35c2df8 It was discovered during research for an upcoming academic paper that a xoshiro128** internal state can be recovered by an external 3rd party, allowing the prediction of UDP ports and DNS IDs in outgoing queries. This could lead to an attacker spoofing the DNS answers with great efficiency and poisoning the DNS cache. The internal random generator has been changed to a cryptographically secure pseudo-random generator. ISC would like to thank Prof. Amit Klein and Omer Ben Simhon from Hebrew University of Jerusalem for bringing this vulnerability to our attention. [GL #5484] New Features# Add dnssec-policy keys configuration check to named-checkconf. 1f5a0405f72 A new option -k is added to named-checkconf that allows checking the dnssec-policy keys configuration against the configured key stores. If the found key files are not in sync with the given dnssec-policy, the check will fail. This is useful to run before migrating to dnssec-policy. [GL #5486] [GL !11011] Feature Changes# Minor refactor of dst code. c6acbaa020b Convert the defines to enums. Initialize the tags more explicitly and less ugly. [GL !11038] Bug Fixes# Use signer name when disabling DNSSEC algorithms. 986816baa74 disable-algorithms could cause DNSSEC validation failures when the parent zone was signed with the algorithms that were being disabled for the child zone. This has been fixed; disable-algorithms now works on a whole-of-zone basis. If the zone's name is at or below the disable-algorithms name the algorithm is disabled for that zone, using deepest match when there are multiple disable-algorithms clauses. [GL #5165] [GL !11014] Rndc sign during ZSK rollover will now replace signatures. d2f551140cd When performing a ZSK rollover, if the new DNSKEY is omnipresent, the rndc sign command now signs the zone completely with the successor key, replacing all zone signatures from the predecessor key with new ones. [GL #5483] [GL !11017] Missing DNSSEC information when CD bit is set in query. 968a6be41fb The RRSIGs for glue records were not being cached correctly for CD=1 queries. This has been fixed. [GL #5502] [GL !10956] Preserve cache when reload fails and reload the server again. 975aeda10b4 Fixes an issue where failing to reconfigure/reload the server would prevent to preserved the views caches on the subsequent server reconfiguration/reload. [GL #5523] [GL !10988] Check plugin config before registering. e2260b80702 In named_config_parsefile(), when checking the validity of named.conf, the checking of plugin correctness was deliberately postponed until the plugin is loaded and registered. However, the checking was never actually done: the plugin_register() implementation was called, but plugin_check() was not. ns_plugin_register() (used by named) now calls the check function before the register function, and aborts if either one fails. ns_plugin_check() (used by named-checkconf) calls only the check function. [GL !11032] BIND 9.20.14# Note The BIND 9.20.14 release was withdrawn after the discovery of a regression in a security fix in it during pre-release testing. BIND 9.20.13# New Features# Add manual mode configuration option to dnsec-policy. 1e435b107f Add a new option manual-mode to dnssec-policy. The intended use is that if it is enabled, it will not automatically move to the next state transition, but instead the transition is logged. Only after manual confirmation with rndc dnssec -step the transition is made. [GL #4606] [GL !10880] Add a new 'servfail-until-ready' configuration option for RPZ. 925af17d21 By default, when named is started it may start answering to queries before the response policy zones are completely loaded and processed. This new feature gives an option to the users to tell named that incoming requests should result in SERVFAIL answer until all the response policy zones are processed and ready. Note that if one or more response policy zones fail to load, named starts responding to queries according to those zones that did load. Note, that enabling this option has no effect when a DNS Response Policy Service (DNSRPS) interface is used. [GL #5222] [GL !10889] Support for parsing HHIT and BRID records has been added. 1f051af24d [GL #5444] [GL !10932] Removed Features# Deprecate the "tkey-gssapi-credential" statement. b239a70cac The tkey-gssapi-keytab statement allows GSS-TSIG to be set up in a simpler and more reliable way than using the tkey-gssapi-credential statement and setting environment variables (e.g. KRB5_KTNAME). Therefore, the tkey-gssapi-credential statement has been deprecated; tkey-gssapi-keytab should be used instead. For configurations currently using a combination of both tkey-gssapi-keytab and tkey-gssapi-credential, the latter should be dropped and the keytab pointed to by tkey-gssapi-keytab should now only contain the credential previously specified by tkey-gssapi-credential. [GL #4204] [GL !10924] Obsolete the "tkey-domain" statement. 9352ae65d7 Mark the tkey-domain statement as obsolete, since it has not had any effect on server behavior since support for TKEY Mode 2 (Diffie-Hellman) was removed (in BIND 9.20.0). [GL #4204] [GL !10926] Feature Changes# Update clang-format style with options added in newer versions. 0c2c477c31 Add and apply InsertBraces statement to add missing curly braces around one-line statements and use ControlStatementsExceptControlMacros for SpaceBeforeParens to remove space between foreach macro and the brace, e.g. FOREACH (x) { becomes FOREACH(x) {. [GL !10864] Bug Fixes# Ensure file descriptors 0-2 are in use. 35dee6eb90 libuv expect file descriptors <= STDERR_FILENO are in use. otherwise, it may abort when closing a file descriptor it opened. [GL #5226] [GL !10908] Prevent spurious SERVFAILs for certain 0-TTL resource records. 6b266b222c Under certain circumstances, BIND 9 can return SERVFAIL when updating existing entries in the cache with new NS, A, AAAA, or DS records with 0-TTL. [GL #5294] [GL !10898] Use DNS_RDATACOMMON_INIT to hide branch differences. a64df9729b Initialization of the common members of rdata type structures varies across branches. Standardize it by using the DNS_RDATACOMMON_INIT macro for all types, so that new types are more likely to use it, and hence backport more cleanly. [GL #5467] [GL !10834] RPZ canonical warning displays zone entry incorrectly. d833676515 When an IPv6 rpz prefix entry is entered incorrectly the log message was just displaying the prefix rather than the full entry. This has been corrected. [GL #5491] [GL !10930] Fix a catalog zone issue when having an unset 'default-primaries' configuration clause. 293e75af28 A catalog zone with an unset default-primaries clause could cause an unexpected termination of the named process after two reloading or reconfiguration commands. This has been fixed. [GL #5494] [GL !10905] Add and use __attribute__((nonnull)) in dnssec-signzone.c. a8eed36d3e Clang 20 was spuriously warning about the possibility of passing a NULL file pointer to fprintf(), which uses the 'nonnull' attribute. To silence the warning, the functions calling fprintf() have been marked with the same attribute to assure that NULL can't be passed to them in the first place. Close #5487 [GL !10913] RPZ 'servfail-until-ready': skip updating SERVFAIL cache. af2fb26325 In order to not pollute the SERVFAIL cache with the configured SERVFAIL answers while RPZ is loading, set the NS_CLIENTATTR_NOSETFC attribute for the client. [GL !10940] BIND 9.20.12# New Features# Support for parsing the DSYNC record has been added. f440fe712d [GL #5440] [GL !10820] Feature Changes# Adaptive memory allocation strategy for qp-tries. 9a046cbed5 qp-tries allocate their nodes (twigs) in chunks to reduce allocator pressure and improve memory locality. The choice of chunk size presents a tradeoff: larger chunks benefit qp-tries with many values (as seen in large zones and resolvers) but waste memory in smaller use cases. Previously, our fixed chunk size of 2^10 twigs meant that even an empty qp-trie would consume 12KB of memory, while reducing this size would negatively impact resolver performance. This MR implements an adaptive chunking strategy that tracks the size of the most recently allocated chunk and doubles the chunk size for each new allocation until reaching a predefined maximum. This approach effectively balances memory efficiency for small tries while maintaining the performance benefits of larger chunk sizes for bigger data structures. [GL #5445] [GL !10804] Add deprecation warnings for RSASHA1, RSASHA1-NSEC3SHA1 and DS digest type 1. 5aefaa4b97 RSASHA1 and RSASHA1-NSEC-SHA1 DNSKEY algorithms have been deprecated by the IETF and should no longer be used for DNSSEC. DS digest type 1 (SHA1) has also been deprecated. Validators are now expected to treat these algorithms and digest as unknown, resulting in some zones being treated as insecure when they were previously treated as secure. Warnings have been added to named and tools when these algorithms and this digest are being used for signing. Zones signed with RSASHA1 or RSASHA1-NSEC-SHA1 should be migrated to a different DNSKEY algorithm. Zones with DS or CDS records with digest type 1 (SHA1) should be updated to use a different digest type (e.g. SHA256) and the digest type 1 records should be removed. Related to #5358 [GL !10738] Bug Fixes# Stale RRsets in a CNAME chain were not always refreshed. ed37c7825e With serve-stale enabled, a CNAME chain that contains a stale RRset, the refresh query doesn't always properly refresh the stale RRsets. This has been fixed. [GL #5243] [GL !10767] Add RPZ extended DNS error for zones with a CNAME override policy configured. 39ad2016c1 When the zone is configured with a CNAME override policy, or the response policy zone contains a wildcard CNAME, the extended DNS error code was not added. This has been fixed. [GL #5342] [GL !10819] Fix a possible crash when adding a zone while recursing. 7a3ec8dd94 A query for a zone that was not yet loaded may yield an unexpected result such as a CNAME or DNAME, triggering an assertion failure. This has been fixed. [GL #5357] [GL !10718] Fix dig issues. 8c50819aa8 When used with the +keepopen option with a TCP connection, iscman:dig could terminate unexpectedly in rare situations. Additionally, iscman:dig could hang and fail to shutdown properly when interrupted during a query. These have been fixed. [GL #5381] [GL !10727] Log dropped or slipped responses in the query-errors category. 47470b586d Responses which were dropped or slipped because of RRL (Response Rate Limiting) were logged in the rate-limit category instead of the query-errors category, as documented in ARM. This has been fixed. [GL #5388] [GL !10725] Separate out adbname type flags. fc689c6525 There are three adbname flags that are used to identify different types of adbname lookups when hashing rather than using multiple hash tables. Separate these to their own structure element as these need to be able to be read without locking the adbname structure. [GL #5404] [GL !10695] Synth-from-dnssec was not working in some scenarios. bc54f059e0 Aggressive use of DNSSEC-Validated cache with NSEC was not working in scenarios when no parent NSEC was not in cache. This has been fixed. [GL #5422] [GL !10754] Clean enough memory when adding new ADB names/entries under memory pressure. b7e7923daa The ADB memory cleaning is opportunistic even when we are under memory pressure (in the overmem condition). Split the opportunistic LRU cleaning and overmem cleaning and make the overmem cleaning always cleanup double of the newly allocated adbname/adbentry to ensure we never allocate more memory than the assigned limit. [GL !10707] Prevent spurious validation failures. 3b98c7cc9d Under rare circumstances, validation could fail if multiple clients simultaneously iterated the same set of signatures.

(CVE-2023-4408) [GL #4234] 6314. [bug] Address race conditions in dns_tsigkey_find(). [GL #4182] 6312. [bug] Conversion from NSEC3 signed to NSEC signed could temporarily put the zone into a state where it was treated as unsigned until the NSEC chain was built. Additionally conversion from one set of NSEC3 parameters to another could also temporarily put the zone into a state where it was treated as unsigned until the new NSEC3 chain was built. [GL #1794] [GL #4495] 6310. [bug] Memory leak in zone.c:sign_zone. When named signed a zone it could leak dst_keys due to a misplaced 'continue'. [GL #4488] 6306. [func] Log more details about the cause of "not exact" errors. [GL #4500] 6304. [bug] The wrong time was being used to determine what RRSIGs where to be generated when dnssec-policy was in use. [GL #4494] 6302. [func] The "trust-anchor-telemetry" statement is no longer marked as experimental.

[bug] BIND might sometimes crash after startup or re-configuration when one 'tls' entry is used multiple times to connect to remote servers due to initialisation attempts from contexts of multiple threads. That has been fixed. [GL #4464] 6290. [bug] Dig +yaml will now report "no servers could be reached" also for UDP setup failure when no other servers or tries are left. [GL #1229] 6287. [bug] Recognize escapes when reading the public key from file. [GL !8502] 6286. [bug] Dig +yaml will now report "no servers could be reached" on TCP connection failure as well as for UDP timeouts.

[bug] Fix a possible assertion failure on an error path in resolver.c:fctx_query(), when using an uninitialized link. [GL #4331] 6254. [cleanup] Add semantic patch to do an explicit cast from char to unsigned char in ctype.h class of functions. [GL #4327] 6252. [test] Python system tests have to be executed by invoking pytest directly. Executing them with the legacy test runner is no longer supported. [GL #4250] 6250. [bug] The wrong covered value was being set by dns_ncache_current for RRSIG records in the returned rdataset structure. This resulted in TYPE0 being reported as the covered value of the RRSIG when dumping the cache contents. [GL #4314] --- 9.18.19 released --- 6246.

[bug] Restore support to read legacy HMAC-MD5 K file pairs. [GL #4154] 6204. [bug] Use NS records for relaxed QNAME-minimization mode. This reduces the number of queries named makes when resolving, as it allows the non-existence of NS RRsets at non-referral nodes to be cached in addition to the referrals that are normally cached. [GL #3325] 6200. [bug] Fix nslookup erroneously reporting a timeout when the input is delayed. [GL #4044] 6199. [bug] Improve HTTP Connection: header protocol conformance in the statistics channel.

[security] Fix serve-stale crash when recursive clients soft quota is reached. (CVE-2022-3924) [GL #3619] 6066. [security] Handle RRSIG lookups when serve-stale is active. (CVE-2022-3736) [GL #3622] 6064. [security] An UPDATE message flood could cause named to exhaust all available memory. This flaw was addressed by adding a new "update-quota" statement that controls the number of simultaneous UPDATE messages that can be processed or forwarded. The default is 100. A stats counter has been added to record events when the update quota is exceeded, and the XML and JSON statistics version numbers have been updated. (CVE-2022-3094) [GL #3523] 6062.

Consider non-stale data when in serve-stale mode. [GL #3678] 6058. [bug] Prevent named from crashing when "rndc delzone" attempts to delete a zone added by a catalog zone. [GL #3745] 6050. [bug] Changes to the RPZ response-policy min-update-interval and add-soa options now take effect as expected when named is reconfigured. [GL #3740] 6048. [bug] Fix a log message error in dns_catz_update_from_db(), where serials with values of 2^31 or larger were logged incorrectly as negative numbers. [GL #3742] 6045. [cleanup] The list of supported DNSSEC algorithms changed log level from "warning" to "notice" to match named's other startup messages. [GL !7217] 6044. [bug] There was an "RSASHA236" typo in a log message. [GL !7206] --- 9.16.36 released --- 6043. [bug] The key file IO locks objects would never get deleted from the hashtable due to off-by-one error. [GL #3727] 6042. [bug] ANY responses could sometimes have the wrong TTL. [GL #3613] 6040. [bug] Speed up the named shutdown time by explicitly canceling all recursing ns_client objects for each ns_clientmgr. [GL #3183] 6039. [bug] Removing a catalog zone from catalog-zones without also removing the referenced zone could leave a dangling pointer. [GL #3683] 6031.

[GL #3468] --- 9.16.35 released --- 6013. [bug] Fix a crash that could happen when you change a dnssec-policy zone with NSEC3 to start using inline-signing. [GL #3591] 6009. [bug] Don't trust a placeholder KEYDATA from the managed-keys zone by adding it into secroots. [GL #2895] 6008. [bug] Fixed a race condition that could cause a crash in dns_zone_synckeyzone(). [GL #3617] 6002. [bug] Fix a resolver prefetch bug when the record's TTL value is equal to the configured prefetch eligibility value, but the record was erroneously not treated as eligible for prefetching. [GL #3603] 6001. [bug] Always call dns_adb_endudpfetch() after calling dns_adb_beginudpfetch() for UDP queries in resolver.c, in order to adjust back the quota. [GL #3598] 6000.
