Notes for BIND 9.18.31
|
|
----------------------
|
|
|
|
New Features
|
|
~~~~~~~~~~~~
|
|
|
|
- Added WALLET type.
|
|
|
|
Add the new record type WALLET (262). This provides a mapping from a
|
|
domain name to a cryptographic currency wallet. Multiple mappings can
|
|
exist if multiple records exist. :gl:`#4947`
|
|
|
|
Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- Allow IXFR-to-AXFR fallback on ``DNS_R_TOOMANYRECORDS``.
|
|
|
|
This change allows fallback from an IXFR failure to AXFR when the
|
|
reason is ``DNS_R_TOOMANYRECORDS``. :gl:`#4928`
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- Fix a statistics channel counter bug when "forward only" zones are
|
|
used.
|
|
|
|
When resolving a zone with a "forward only" policy, and finding out
|
|
that all the forwarders were marked as "bad", the "ServerQuota"
|
|
counter of the statistics channel was incorrectly increased. This has
|
|
been fixed. :gl:`#1793`
|
|
|
|
- Fix a bug in the static-stub implementation.
|
|
|
|
Static-stub addresses and addresses from other sources were being
|
|
mixed together, resulting in static-stub queries going to addresses
|
|
not specified in the configuration, or alternatively, static-stub
|
|
addresses being used instead of the correct server addresses.
|
|
:gl:`#4850`
|
|
|
|
- Don't allow :any:`statistics-channels` if libxml2 and libjson-c are
|
|
not configured.
|
|
|
|
When BIND 9 is not configured with the libxml2 and libjson-c
|
|
libraries, the use of the :any:`statistics-channels` option is a fatal
|
|
error. :gl:`#4895`
|
|
|
|
- Limit the outgoing UDP send queue size.
|
|
|
|
If the operating system UDP queue got full and the outgoing UDP
|
|
sending started to be delayed, BIND 9 could exhibit memory spikes as
|
|
it tried to enqueue all the outgoing UDP messages. It now tries to
|
|
deliver the outgoing UDP messages synchronously; if that fails, it
|
|
drops the outgoing DNS message that would get queued up and then
|
|
timeout on the client side. :gl:`#4930`
|
|
|
|
- Do not set ``SO_INCOMING_CPU``.
|
|
|
|
Remove the ``SO_INCOMING_CPU`` setting as kernel scheduling performs
|
|
better without constraints. :gl:`#4936`
|
|
|
|
|
