Notes for BIND 9.19.22
----------------------
Security Fixes
~~~~~~~~~~~~~~
- None.
New Features
~~~~~~~~~~~~
- The ``tls`` block was extended with a new ``cipher-suites`` option
that allows setting allowed cipher suites for TLSv1.3. Please
consult the documentation for additional details.
:gl:`#3504`
- The statistics channel now includes counters that indicate the number
of currently connected TCP IPv4/IPv6 clients. :gl:`#4425`
- The statistics channel's incoming zone transfers information now also shows
the zones' "first refresh" flag, which indicates that a zone is not fully
ready yet, and its first ever refresh is pending or is in-progress. The number
of such zones is now also exposed by the ``rndc status`` command. :gl:`#4241`
- Add HSM support to :any:`dnssec-policy`. You can now configure keys with a
``key-store`` that allows you to set the directory to store the key files and
set a PKCS#11 URI string. The latter requires OpenSSL 3 and a valid PKCS#11
provider to be configured for OpenSSL. :gl`#1129`.
Removed Features
~~~~~~~~~~~~~~~~
- BIND 9 no longer supports non-zero :any:`stale-answer-client-timeout` values,
when the feature is turned on. When using a non-zero value, ``named`` now
generates a warning log message, and treats the value as ``0``. :gl:`#4447`
Feature Changes
~~~~~~~~~~~~~~~
- The ``dnssec-validation yes`` option now requires an explicitly configured
:any:`trust-anchors` statement. If using manual trust anchors is not
operationally required, then please consider using ``dnssec-validation auto``
instead. :gl:`#4373`
Bug Fixes
~~~~~~~~~
- Changes to ``listen-on`` statements were ignored on reconfiguration
unless the port or interface address was changed, making it
impossible to change a related listener transport type. That issue
has been fixed.
ISC would like to thank Thomas Amgarten for bringing this issue to
our attention. :gl:`#4518`, :gl:`#4528`
- A use-after-free assertion might get triggered when the overmem cache
cleaning triggers. :gl:`#4595`
ISC would like to thank to Jinmei Tatuya from Infoblox for bringing
this issue to our attention.
- A regression in cache-cleaning code enabled memory use to grow
significantly more quickly than before, until the configured
:any:`max-cache-size` limit was reached. This has been fixed.
:gl:`#4596`
Known Issues
~~~~~~~~~~~~
- There are no new known issues with this release. See :ref:`above
<relnotes_known_issues>` for a list of all known issues affecting this
BIND 9 branch.
