Notes for BIND 9.16.16
|
|
----------------------
|
|
|
|
Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- DNSSEC responses containing NSEC3 records with iteration counts
|
|
greater than 150 are now treated as insecure. :gl:`#2445`
|
|
|
|
- The maximum supported number of NSEC3 iterations that can be
|
|
configured for a zone has been reduced to 150. :gl:`#2642`
|
|
|
|
- The default value of the ``max-ixfr-ratio`` option was changed to
|
|
``unlimited``, for better backwards compatibility in the stable
|
|
release series. :gl:`#2671`
|
|
|
|
- Zones that want to transition from secure to insecure mode without
|
|
becoming bogus in the process must now have their ``dnssec-policy``
|
|
changed first to ``insecure``, rather than ``none``. After the DNSSEC
|
|
records have been removed from the zone, the ``dnssec-policy`` can be
|
|
set to ``none`` or removed from the configuration. Setting the
|
|
``dnssec-policy`` to ``insecure`` causes CDS and CDNSKEY DELETE
|
|
records to be published. :gl:`#2645`
|
|
|
|
- The implementation of the ZONEMD RR type has been updated to match
|
|
:rfc:`8976`. :gl:`#2658`
|
|
|
|
- The ``draft-vandijk-dnsop-nsec-ttl`` IETF draft was implemented:
|
|
NSEC(3) TTL values are now set to the minimum of the SOA MINIMUM value
|
|
or the SOA TTL. :gl:`#2347`
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- It was possible for corrupt journal files generated by an earlier
|
|
version of ``named`` to cause problems after an upgrade. This has been
|
|
fixed. :gl:`#2670`
|
|
|
|
- TTL values in cache dumps were reported incorrectly when
|
|
``stale-cache-enable`` was set to ``yes``. This has been fixed.
|
|
:gl:`#389` :gl:`#2289`
|
|
|
|
- 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`
|
|
|
|
- ``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`
|
|
|
|
- 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`
|
|
|
|
- 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`
