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 9.16.8
|
|
---------------------
|
|
|
|
New Features
|
|
~~~~~~~~~~~~
|
|
|
|
- Add a new ``rndc`` command, ``rndc dnssec -rollover``, which triggers
|
|
a manual rollover for a specific key. :gl:`#1749`
|
|
|
|
- Add a new ``rndc`` command, ``rndc dumpdb -expired``, which dumps the
|
|
cache database, including expired RRsets that are awaiting cleanup, to
|
|
the ``dump-file`` for diagnostic purposes. :gl:`#1870`
|
|
|
|
Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- DNS Flag Day 2020: The default EDNS buffer size has been changed from
|
|
4096 to 1232 bytes. According to measurements done by multiple
|
|
parties, this should not cause any operational problems as most of the
|
|
Internet "core" is able to cope with IP message sizes between
|
|
1400-1500 bytes; the 1232 size was picked as a conservative minimal
|
|
number that could be changed by the DNS operator to an estimated path
|
|
MTU minus the estimated header space. In practice, the smallest MTU
|
|
witnessed in the operational DNS community is 1500 octets, the maximum
|
|
Ethernet payload size, so a useful default for maximum DNS/UDP payload
|
|
size on reliable networks would be 1400 bytes. :gl:`#2183`
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- ``named`` reported an invalid memory size when running in an
|
|
environment that did not properly report the number of available
|
|
memory pages and/or the size of each memory page. :gl:`#2166`
|
|
|
|
- With multiple forwarders configured, ``named`` could fail the
|
|
``REQUIRE(msg->state == (-1))`` assertion in ``lib/dns/message.c``,
|
|
causing it to crash. This has been fixed. :gl:`#2124`
|
|
|
|
- ``named`` erroneously performed continuous key rollovers for KASP
|
|
policies that used algorithm Ed25519 or Ed448 due to a mismatch
|
|
between created key size and expected key size. :gl:`#2171`
|
|
|
|
- Updating contents of an RPZ zone which contained names spelled using
|
|
varying letter case could cause some processing rules in that RPZ zone
|
|
to be erroneously ignored. :gl:`#2169`
