New Features

~~~~~~~~~~~~

|
|
|
|
|
|
- New configuration options, ``tcp-receive-buffer``, ``tcp-send-buffer``,
|
|
|
|
|
``udp-receive-buffer``, and ``udp-send-buffer``, have been added. These
|
|
|
|
|
options allows the operator to fine tune the receiving and sending
|
|
|
|
|
buffers in the operating system. On busy servers, increasing the value
|
|
|
|
|
of the receive buffers can prevent the server from dropping the packets
|
|
|
|
|
during short spikes, and decreasing the value would prevent the server to
|
|
|
|
|
became clogged up with queries that are too old and have already timeouted
|
|
|
|
|
on the receiving side. :gl:`#2313`

- Run zone dumping tasks on separate asynchronous thread pools. This change
|
|
|
|
|
makes zone dumping no longer block networking I/O. :gl:`#2732`

|
- The interface handling code has been refactored to use fewer resources,
|
|
|
|
|
which should lead to less memory fragmentation and better startup
|
|
|
|
|
performance. :gl:`#2433`

Bug Fixes
|
|
|
|
|
~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
- Fix a race condition in reading and writing key files for KASP zones in
|
|
|
|
|
multiple views. :gl:`#1875`
|
|
|
|
|
|
|
|
|
|
- Check ``key-directory`` conflicts in ``named.conf`` for zones in multiple
|
|
|
|
|
views with different ``dnssec-policy``. Using the same ``key-directory`` for
|
|
|
|
|
such zones is not allowed. :gl:`#2463`
|
2021-05-14 11:15:30 +10:00
|
|
|
|
|
|
|
|
- ``named-checkconf`` now complains if zones with ``dnssec-policy`` reference
|
|
|
|
|
the same zone file more than once. :gl:`#2603`
|
|
|
|
|
|
|
|
|
|
- The calculation of the estimated IXFR transaction size by
|
|
|
|
|
`dns_journal_iter_init()` was invalid. This resulted in excessive
|
|
|
|
|
AXFR-style-IXFR responses. :gl:`#2685`
|
2021-05-26 17:41:11 -07:00
|
|
|
|
|
|
|
|
- If a query was answered with stale data on a server with DNS64 enabled,
|
|
|
|
|
an assertion could occur if a non-stale answer arrived afterward. This
|
|
|
|
|
has been fixed. :gl:`#2731`
|
2021-05-27 16:04:07 +02:00
|
|
|
|
|
|
|
|
- Fixed an assertion failure that could occur if stale data was used
|
|
|
|
|
to answer a query, and then a prefetch was triggered after the query
|
|
|
|
|
was restarted (for example, to follow a CNAME). :gl:`#2733`
|
