Notes for BIND 9.16.19
|
|
----------------------
|
|
|
|
New Features
|
|
~~~~~~~~~~~~
|
|
|
|
- Using a new configuration option, ``parental-agents``, each zone can
|
|
now be associated with a list of servers that can be used to check the
|
|
DS RRset in the parent zone. This enables automatic KSK rollovers.
|
|
:gl:`#1126`
|
|
|
|
Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- IP fragmentation has been disabled for outgoing UDP sockets. Errors
|
|
triggered by sending DNS messages larger than the specified path MTU
|
|
are properly handled by sending empty DNS replies with the ``TC``
|
|
(TrunCated) bit set, which forces DNS clients to fall back to TCP.
|
|
:gl:`#2790`
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- The code managing :rfc:`5011` trust anchors created an invalid
|
|
placeholder keydata record upon a refresh failure, which prevented the
|
|
database of managed keys from subsequently being read back. This has
|
|
been fixed. :gl:`#2686`
|
|
|
|
- Signed, insecure delegation responses prepared by ``named`` either
|
|
lacked the necessary NSEC records or contained duplicate NSEC records
|
|
when both wildcard expansion and CNAME chaining were required to
|
|
prepare the response. This has been fixed. :gl:`#2759`
|
|
|
|
- If ``nsupdate`` sends an SOA request and receives a REFUSED response,
|
|
it now fails over to the next available server. :gl:`#2758`
|
|
|
|
- A bug that caused the NSEC3 salt to be changed on every restart for
|
|
zones using KASP has been fixed. :gl:`#2725`
|
|
|
|
- The configuration-checking code failed to account for the inheritance
|
|
rules of the ``dnssec-policy`` option. This has been fixed.
|
|
:gl:`#2780`
|
|
|
|
- The fix for :gl:`#1875` inadvertently introduced a deadlock: when
|
|
locking key files for reading and writing, the ``in-view`` logic was
|
|
not considered. This has been fixed. :gl:`#2783`
|
|
|
|
- A race condition could occur where two threads were competing for the
|
|
same set of key file locks, leading to a deadlock. This has been
|
|
fixed. :gl:`#2786`
|
|
|
|
