Notes for BIND 9.19.0
---------------------
Known Issues
~~~~~~~~~~~~
- According to :rfc:`8310`, Section 8.1, the ``Subject`` field MUST NOT
be inspected when verifying a remote certificate while establishing a
DNS-over-TLS connection. Only ``subjectAltName`` must be checked
instead. Unfortunately, some quite old versions of cryptographic
libraries might lack the ability to ignore the ``Subject`` field. This
should have minimal production-use consequences, as most of the
production-ready certificates issued by certificate authorities will
have ``subjectAltName`` set. In such cases, the ``Subject`` field is
ignored. Only old platforms are affected by this, e.g. those supplied
with OpenSSL versions older than 1.1.1. :gl:`#3163`
New Features
~~~~~~~~~~~~
- Add support for remote TLS certificate verification, both to
:iscman:`named` and :iscman:`dig`, making it possible to implement
Strict and Mutual TLS authentication, as described in :rfc:`9103`,
Section 9.3. :gl:`#3163`
- :iscman:`dnssec-verify` and :iscman:`dnssec-signzone` now accept a
``-J`` option to specify a journal file to read when loading the zone
to be verified or signed. :gl:`#2486`
Removed Features
~~~~~~~~~~~~~~~~
- The ``keep-order-response`` option has been declared obsolete and the
functionality has been removed. :iscman:`named` expects DNS clients to
be fully compliant with :rfc:`7766`. :gl:`#3140`
Feature Changes
~~~~~~~~~~~~~~~
- Run RPZ updates on the specialized "offload" threads to reduce the
amount of time they block query processing on the main networking
threads. This should increase the responsiveness of :iscman:`named`
when RPZ updates are being applied after an RPZ zone has been
successfully transferred. :gl:`#3190`
