Security Fixes
ISC would like to thank Kishore Kumar Kothapalli of Infoblox for
bringing this vulnerability to our attention. :gl:`#2899`
-Known Issues
-~~~~~~~~~~~~
-
-- None.
-
New Features
~~~~~~~~~~~~
make achieving perfect forward secrecy (PFS) possible for DNS-over-TLS
(DoT) and DNS-over-HTTPS (DoH). :gl:`#2796`
-- Implement incremental resizing of RBT hash tables to perform the rehashing
- gradually instead all-at-once to be able to grow the memory usage gradually
- while keeping steady response rate during the rehashing. :gl:`#2941`
-
-- Add finer-grained ``update-policy`` rule types, ``krb5-subdomain-self-rhs``
- and ``ms-subdomain-self-rhs``, that restrict updates to SRV and PTR records
- so that their content can only match the machine name embedded in the
- Kerberos principal making the change. :gl:`#481`
-
Removed Features
~~~~~~~~~~~~~~~~
enabled in ``named`` at build time have been removed. New-style DLZ
modules should be used as a replacement. :gl:`#2814`
-- Add support for OpenSSL 3.0.0. OpenSSL 3.0.0 deprecated 'engine' support.
- If OpenSSL 3.0.0 has been built without support for deprecated functionality
- pkcs11 via engine_pkcs11 is no longer available. At this point in time
- there is no replacement ``provider`` for pkcs11 which is the replacement to
- the ``engine API``. :gl:`#2843`
-
- Support for the ``map`` zone file format (``masterfile-format map;``)
has been removed. Users relying on the ``map`` format are advised to
convert their zones to the ``raw`` format with ``named-compilezone``
``notify-source``, ``parental-source``, and/or for their respective
IPv6 counterparts. :gl:`#2888`
-- Because the old socket manager API has been removed, "socketmgr"
- statistics are no longer reported by the statistics channel. :gl:`#2926`
-
- Zone transfers over TLS (XoT) now need the ``dot`` Application-Layer
Protocol Negotiation (ALPN) token to be selected in the TLS handshake,
as required by :rfc:`9103` section 7.1. :gl:`#2794`
-- `UseSTD3ASCIIRules`_ is now enabled for IDN support. This enables additional
- validation rules for domains and hostnames within dig. :gl:`#1610`
-
-.. _UseSTD3ASCIIRules: http://www.unicode.org/reports/tr46/#UseSTD3ASCIIRules
-
-- The default for ``dnssec-dnskey-kskonly`` is changed to ``yes``. This means
- that DNSKEY, CDNSKEY, and CDS RRsets are now only signed with the KSK by
- default. The additional signatures from the ZSK that are added if the option
- is set to ``no`` add to the DNS response payload without offering added value.
- :gl:`#1316`
-
-- The output of ``rndc serve-stale status`` has been clarified. It now
- explicitly reports whether retention of stale data in the cache is enabled
- (``stale-cache-enable``), and whether returning of such data in responses is
- enabled (``stale-answer-enable``). :gl:`#2742`
-
-- The default for ``dnssec-policy``'s ``nsec3param`` is changed to use
- no extra iterations and no salt. :gl:`#2956`.
-
Bug Fixes
~~~~~~~~~
``named`` startup, it could fail to listen for TCP connections on the
newly added interfaces. :gl:`#2852`
-- Reloading a catalog zone which referenced a missing/deleted member
- zone triggered a runtime check failure, causing ``named`` to exit
- prematurely. This has been fixed. :gl:`#2308`
-
- Under specific circumstances, zone transfers over TCP and TLS could be
interrupted prematurely. This has been fixed. :gl:`#2917`
-
-- Logfiles using ``timestamp``-style suffixes were not always correctly
- removed when the number of files exceeded the limit set by ``versions``.
- :gl:`#828`
-
-- Some lame delegations could trigger a dependency loop, in which a
- resolver fetch was waiting for a name server address lookup which was
- waiting for the same resolver fetch. This could cause a recursive lookup
- to hang until timing out. This now detected and avoided. :gl:`#2927`
