Define a :gl: Sphinx role that takes a GitLab issue/MR number as an argument and creates a hyperlink to the relevant ISC GitLab URL. This makes it easy to reach ISC GitLab pages directly from the release notes. Make all GitLab references in the release notes use the new Sphinx role.

Notes for BIND 9.17.9
|
|
---------------------
|
|
|
|
New Features
|
|
~~~~~~~~~~~~
|
|
|
|
- ``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
|
|
without making it bogus in the process; changing to ``dnssec-policy
|
|
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`
|
|
|
|
- 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).
|
|
``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`
|
|
|
|
- ``named`` no longer attempts to assign threads to CPUs outside the CPU
|
|
affinity set. Thanks to Ole Bjørn Hessen. :gl:`#2245`
|
|
|
|
- When reconfiguring ``named``, removing ``auto-dnssec`` did not turn
|
|
off DNSSEC maintenance. This has been fixed. :gl:`#2341`
|
|
|
|
- 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`
