Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- The ``allow-transfers`` option was extended to accept additional
|
|
``port`` and ``transport`` parameters, to further restrict zone
|
|
transfers to a particular port and DNS transport protocol. Either of
|
|
these options can be specified.
|
|
|
|
For example: ``allow-transfer port 853 transport tls { any; };``
|
|
:gl:`#2776`
|
|
|
|
- `UseSTD3ASCIIRules`_ is now disabled for IDN support. This disables additional
|
|
validation rules for domain names in dig because applying the rules would
|
|
silently strip characters not-allowed in hostnames such as underscore (``_``)
|
|
or wildcard (``*``) characters. This reverts change :gl:`!5738` from the
|
|
previous release. :gl:`#1610`
|
|
|
|
- Previously, when an incoming TCP connection could not be accepted because the client
|
|
closed the connection early, an error message of ``TCP connection
|
|
failed: socket is not connected`` was logged. This message has been changed
|
|
to ``Accepting TCP connection failed: socket is not connected``. The
|
|
severity level at which this type of message is logged has also
|
|
been changed from ``error`` to ``info`` for the following triggering
|
|
events: ``socket is not connected``, ``quota reached``, and ``soft
|
|
quota reached``. :gl:`#2700`
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- Removing a configured ``catalog-zone`` clause from the configuration, running
|
|
``rndc reconfig``, then bringing back the removed ``catalog-zone`` clause and
|
|
running ``rndc reconfig`` again caused ``named`` to crash. This has been fixed.
|
|
:gl:`#1608`
|
|
|
|
- The resolver could hang on shutdown due to dispatch resources not being
|
|
cleaned up when a TCP connection was reset. This has been fixed. :gl:`#3026`
