- Update to 9.16.19
* 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]
* create_keydata() 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]
* KASP support was extended with the "check DS" feature.
Zones with "dnssec-policy" and "parental-agents"
configured now check for DS presence and can perform
automatic KSK rollovers. [GL #1126]
* Rescheduling a setnsec3param() task when a zone failed
to load on startup caused a hang on shutdown. This has
been fixed. [GL #2791]
* The configuration-checking code failed to account for
the inheritance rules of the "dnssec-policy" option.
This has been fixed. [GL #2780]
* If nsupdate sends an SOA request and receives a REFUSED
response, it now fails over to the next available
server. [GL #2758]
* For UDP messages larger than the path MTU, named now
sends an empty response with the TC (TrunCated) bit set.
In addition, setting the DF (Don't Fragment) flag on
outgoing UDP sockets was re-enabled. [GL #2790]
* Views with recursion disabled are now configured with a
default cache size of 2 MB unless "max-cache-size" is
explicitly set. This prevents cache RBT hash tables from
being needlessly preallocated for such views. [GL #2777]
* Change 5644 inadvertently introduced a deadlock: when
locking the key file mutex for each zone structure in a
different view, the "in-view" logic was not considered.
This has been fixed. [GL #2783]
* Increasing "max-cache-size" for a running named instance
(using "rndc reconfig") did not cause the hash tables
used by cache databases to be grown accordingly. This
has been fixed. [GL #2770]
* 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]
* A bug that caused the NSEC3 salt to be changed on every
restart for zones using KASP has been fixed. [GL #2725] (forwarded request 909186 from polslinux)
