--- 9.16.20 released --- 5689. [security] An assertion failure occurred when named attempted to send a UDP packet that exceeded the MTU size, if Response Rate Limiting (RRL) was enabled. (CVE-2021-25218) [GL #2856] 5688. [bug] Zones using KASP and inline-signed zones failed to apply changes from the unsigned zone to the signed zone under certain circumstances. This has been fixed. [GL #2735] 5687. [bug] "rndc reload <zonename>" could trigger a redundant reload for an inline-signed zone whose zone file was not modified since the last "rndc reload". This has been fixed. [GL #2855] 5686. [func] The number of internal data structures allocated for each zone was reduced. [GL #2829] 5685. [bug] named failed to check the opcode of responses when performing zone refreshes, stub zone updates, and UPDATE forwarding. This has been fixed. [GL #2762] 5682. [bug] Some changes to "zone-statistics" settings were not properly processed by "rndc reconfig". This has been fixed. [GL #2820] 5681. [func] Relax the checks in the dns_zone_cdscheck() function to allow CDS and CDNSKEY records in the zone that do not match an existing DNSKEY record, as long as the algorithm matches. This allows a clean rollover from one provider to another in a multi-signer DNSSEC configuration. [GL #2710] 5679. [func] Thread affinity is no longer set. [GL #2822] 5678. [bug] The "check DS" code failed to release all resources upon named shutdown when a refresh was in progress. This has been fixed. [GL #2811] 5672. [bug] Authentication of rndc messages could fail if a "controls" statement was configured with multiple key algorithms for the same listener. This has been fixed. [GL #2756] --- 9.16.19 released --- 5671. [bug] A race condition could occur where two threads were competing for the same set of key file locks, leading to a deadlock. This has been fixed. [GL #2786] 5670. [bug] create_keydata() created an invalid placeholder keydata record upon a refresh failure, which prevented the database of managed keys from subsequently being read back. This has been fixed. [GL #2686] 5669. [func] KASP support was extended with the "check DS" feature. Zones with "dnssec-policy" and "parental-agents" configured now check for DS presence and can perform automatic KSK rollovers. [GL #1126] 5668. [bug] Rescheduling a setnsec3param() task when a zone failed to load on startup caused a hang on shutdown. This has been fixed. [GL #2791] 5667. [bug] The configuration-checking code failed to account for the inheritance rules of the "dnssec-policy" option. This has been fixed. [GL #2780] 5666. [doc] The safe "edns-udp-size" value was tweaked to match the probing value from BIND 9.16 for better compatibility. [GL #2183] 5665. [bug] If nsupdate sends an SOA request and receives a REFUSED response, it now fails over to the next available server. [GL #2758] 5664. [func] For UDP messages larger than the path MTU, named now sends an empty response with the TC (TrunCated) bit set. In addition, setting the DF (Don't Fragment) flag on outgoing UDP sockets was re-enabled. [GL #2790] 5662. [bug] Views with recursion disabled are now configured with a default cache size of 2 MB unless "max-cache-size" is explicitly set. This prevents cache RBT hash tables from being needlessly preallocated for such views. [GL #2777] 5661. [bug] Change 5644 inadvertently introduced a deadlock: when locking the key file mutex for each zone structure in a different view, the "in-view" logic was not considered. This has been fixed. [GL #2783] 5658. [bug] Increasing "max-cache-size" for a running named instance (using "rndc reconfig") did not cause the hash tables used by cache databases to be grown accordingly. This has been fixed. [GL #2770] 5655. [bug] Signed, insecure delegation responses prepared by named either lacked the necessary NSEC records or contained duplicate NSEC records when both wildcard expansion and CNAME chaining were required to prepare the response. This has been fixed. [GL #2759] 5653. [bug] A bug that caused the NSEC3 salt to be changed on every restart for zones using KASP has been fixed. [GL #2725] --- 9.16.18 released --- 5660. [bug] The configuration-checking code failed to account for the inheritance rules of the "key-directory" option. [GL #2778] 5659. [bug] When preparing DNS responses, named could replace the letters 'W' (uppercase) and 'w' (lowercase) with '\000'. This has been fixed. [GL #2779] --- 9.16.17 released --- 5652. [bug] A copy-and-paste error in change 5584 caused the IP_DONTFRAG socket option to be enabled instead of disabled. This has been fixed. [GL #2746] 5651. [func] Refactor zone dumping to be processed asynchronously via the uv_work_t thread pool API. [GL #2732] 5650. [bug] Prevent a crash that could occur if serve-stale was enabled and a prefetch was triggered during a query restart. [GL #2733] 5649. [bug] If a query was answered with stale data on a server with DNS64 enabled, an assertion could occur if a non-stale answer arrived afterward. [GL #2731] 5648. [bug] The calculation of the estimated IXFR transaction size in dns_journal_iter_init() was invalid. [GL #2685] 5644. [bug] Fix a race condition in reading and writing key files for zones using KASP and configured in multiple views. [GL #1875] 5643. [cleanup] "make install" no longer creates an empty ${localstatedir}/run directory. [GL #2709] 5642. [bug] Zones which are configured in multiple views with different values set for "dnssec-policy" and with identical values set for "key-directory" are now detected and treated as a configuration error. [GL #2463] 5641. [bug] Address a potential memory leak in dst_key_fromnamedfile(). [GL #2689] 5639. [bug] Check that the first and last SOA record of an AXFR are consistent. [GL #2528] 5638. [bug] Improvements related to network manager/task manager integration: - isc_managers_create() and isc_managers_destroy() functions were added to handle setup and teardown of netmgr, taskmgr, timermgr, and socketmgr, since these require a precise order of operations now. - Event queue processing is now quantized to prevent infinite looping. - The netmgr can now be paused from within a netmgr thread. - Deadlocks due to a conflict between netmgr's pause/resume and listen/stoplistening operations were fixed. [GL #2654] 5633. [doc] The "inline-signing" option was incorrectly described as being inherited from the "options"/"view" levels and was incorrectly accepted at those levels without effect. This has been fixed. [GL #2536] 5624. [func] Task manager events are now processed inside network manager loops. The task manager no longer needs its own set of worker threads, which improves resolver performance. [GL #2638] --- 9.16.16 released --- 5637. [func] Change the default value of the "max-ixfr-ratio" option to "unlimited". [GL #2671] 5636. [bug] named and named-checkconf did not report an error when multiple zones with the "dnssec-policy" option set were using the same zone file. This has been fixed. [GL #2603] 5635. [bug] Journal compaction could fail when a journal with invalid transaction headers was not detected at startup. This has been fixed. [GL #2670] 5634. [bug] If "dnssec-policy" was active and a private key file was temporarily offline during a rekey event, named could incorrectly introduce replacement keys and break a signed zone. This has been fixed. [GL #2596] 5633. [doc] The "inline-signing" option was incorrectly described as being inherited from the "options"/"view" levels and was incorrectly accepted at those levels without effect. This has been fixed. [GL #2536] 5632. [func] Add a new built-in KASP, "insecure", which is used to transition a zone from a signed to an unsigned state. The existing built-in KASP "none" should no longer be used to unsign a zone. [GL #2645] 5631. [protocol] Update the implementation of the ZONEMD RR type to match RFC 8976. [GL #2658] 5630. [func] Treat DNSSEC responses containing NSEC3 records with iteration counts greater than 150 as insecure. [GL #2445] 5629. [func] Reduce the maximum supported number of NSEC3 iterations that can be configured for a zone to 150. [GL #2642] 5627. [bug] RRSIG(SOA) RRsets placed anywhere other than at the zone apex were triggering infinite resigning loops. This has been fixed. [GL #2650] 5626. [bug] When generating zone signing keys, KASP now also checks for key ID conflicts among newly created keys, rather than just between new and existing ones. [GL #2628] 5625. [bug] A deadlock could occur when multiple "rndc addzone", "rndc delzone", and/or "rndc modzone" commands were invoked simultaneously for different zones. This has been fixed. [GL #2626] 5622. [cleanup] The lib/samples/ directory has been removed, as export versions of libraries are no longer maintained. [GL !4835] 5619. [protocol] Implement draft-vandijk-dnsop-nsec-ttl, updating the protocol such that NSEC(3) TTL values are set to the minimum of the SOA MINIMUM value or the SOA TTL. [GL #2347] 5618. [bug] Change 5149 introduced some inconsistencies in the way record TTLs were presented in cache dumps. These inconsistencies have been eliminated. [GL #389] [GL #2289] |
