- ``ipv4only.arpa`` is now served when DNS64 is configured. [GL #385]

Feature Changes

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

|
|
|
- It is now possible to transition a zone from secure to insecure mode
|
2021-01-08 16:16:51 +01:00
|
|
|
without making it bogus in the process; changing to ``dnssec-policy
|
2020-12-08 09:42:51 +01:00
|
|
|
none;`` also causes CDS and CDNSKEY DELETE records to be published, to
|
|
|
|
|
signal that the entire DS RRset at the parent must be removed, as
|
|
|
|
|
described in RFC 8078. [GL #1750]
|
2020-12-16 22:09:14 +01:00
|
|
|
|
|
|
|
|
- When using the ``unixtime`` or ``date`` method to update the SOA
|
|
|
|
|
serial number, ``named`` and ``dnssec-signzone`` silently fell back to
|
|
|
|
|
the ``increment`` method to prevent the new serial number from being
|
|
|
|
|
smaller than the old serial number (using serial number arithmetics).
|
2021-01-08 16:16:51 +01:00
|
|
|
``dnssec-signzone`` now prints a warning message, and ``named`` logs a
|
|
|
|
|
warning, when such a fallback happens. [GL #2058]

Bug Fixes

~~~~~~~~~
|
|
|
|

|
|
|
- Multiple threads could attempt to destroy a single RBTDB instance at
|
|
|
|
|
the same time, resulting in an unpredictable but low-probability
|
|
|
|
|
assertion failure in ``free_rbtdb()``. This has been fixed. [GL #2317]
|
|
|
|
|
|
2021-01-08 16:16:51 +01:00
|
|
|
- ``named`` no longer attempts to assign threads to CPUs outside the CPU
|
|
|
|
|
affinity set. Thanks to Ole Bjørn Hessen. [GL #2245]
|
2020-12-23 12:03:26 +01:00
|
|
|
|
2021-01-08 16:16:51 +01:00
|
|
|
- When reconfiguring ``named``, removing ``auto-dnssec`` did not turn
|
2020-12-08 09:55:36 +01:00
|
|
|
off DNSSEC maintenance. This has been fixed. [GL #2341]
|

2021-01-08 16:16:51 +01:00
|
|
|
- The report of intermittent BIND assertion failures triggered in
|
|
|
|
|
``lib/dns/resolver.c:dns_name_issubdomain()`` has now been closed
|
|
|
|
|
without further action. Our initial response to this was to add
|
|
|
|
|
diagnostic logging instead of terminating ``named``, anticipating that
|
|
|
|
|
we would receive further useful troubleshooting input. This workaround
|
|
|
|
|
first appeared in BIND releases 9.17.5 and 9.16.7. However, since
|
|
|
|
|
those releases were published, there have been no new reports of
|
|
|
|
|
assertion failures matching this issue, but also no further diagnostic
|
|
|
|
|
input, so we have closed the issue. [GL #2091]
