Similar to "notify-source" and "transfer-source", add options to
set the source address when querying parental agents for DS records.
(manually picked from commit 2872d6a12e)
Introduce a way to configure parental agents that can be used to
query DS records to be used in automatic key rollovers.
(manually picked from commit 0311705d4b)
Change the primaries configuration objects to the more generic
remote-servers, that we can reuse for other purposes (such as
parental-agents).

Generally, the issues fixed here are missing articles, wrong articles
and double articles. We especially like "the the".

When backporting the Don't Fragment UDP socket option, it was noticed
that the edns-udp-size probing uses 1432 as one of the values to be
probed and the documentation would be recommending 1400 as the safe
value. As the safe value can be from the 1400-1500 interval, the
documentation has been changed to match the probed value, so we do not
skip it.
Instead of just disabling the PMTUD mechanism on the UDP sockets, we
now set IP_DONTFRAG (IPV6_DONTFRAG) flag. That means that the UDP
packets won't get ever fragmented. If the ICMP packets are lost the
UDP will just timeout and eventually be retried over TCP.
Expand the description of mirror zones in the ARM by adding a brief
discussion of how the validation process works for AXFR and IXFR. Move
the paragraph mentioning the "file" option higher up. Apply minor
stylistic and whitespace-related tweaks to the relevant section of the
ARM.
(cherry picked from commit d877aa9adf)
Improve the description of the "max-cache-size" option in the ARM by
focusing on its meaning for multiple views and default values.
Add mention of a hash table preallocation.

Commit 070c5fff49 updated the man pages
to contents produced using:
- Sphinx 4.0.2
- sphinx-rtd-theme 0.5.2
- docutils 0.17.1
However, sphinx-rtd-theme 0.5.2 is incompatible with versions 0.17+ of
the docutils package. This problem was addressed in the Docker image
used for building man pages by downgrading the docutils package to
version 0.16.
Regenerate the man pages again, this time using:
- Sphinx 4.0.2
- sphinx-rtd-theme 0.5.2
- docutils 0.16
This is necessary to prevent the "docs" GitLab CI job from failing.
(cherry picked from commit 6a2daddf5b)
When the feature was backported, we should have leave it disabled by
default, it turns out the default `100%` is producing some unexpected
results (under investigation), so for the time being, we are going to to
disable the max-ixfr-ratio.
Update the ARM to mention the new built-in "insecure" policy. Update
the DNSSEC guide recipe "Revert to unsigned" to add the additional
step of reconfiguring the zone to "insecure" (instead of immediately
set it to "none").

By default readthedocs.org uses Sphinx 1.8.5, but MR !4563 has
introduced depedency on ReferenceRole class which is available only in
Sphinx 2.0.0.
Path to doc/arm/requirements.txt needs to be configured in
readthedocs.org.
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.

While working on the serve-stale backports, I noticed the following
oddities:
1. In the serve-stale system test, in one case we keep track of the
time how long it took for dig to complete. In commit
aaed7f9d8c, the code removed the
exception to check for result == ISC_R_SUCCESS on stale found
answers, and adjusted the test accordingly. This failed to update
the time tracking accordingly. Move the t1/t2 time track variables
back around the two dig commands to ensure the lookups resolved
faster than the resolver-query-timeout.
2. We can remove the setting of NS_QUERYATTR_STALEOK and
DNS_RDATASETATTR_STALE_ADDED on the "else if (stale_timeout)"
code path, because they are added later when we know we have
actually found a stale answer on a stale timeout lookup.
3. We should clear the NS_QUERYATTR_STALEOK flag from the client
query attributes instead of DNS_RDATASETATTR_STALE_ADDED (that
flag is set on the rdataset attributes).
4. In 'bin/named/config.c' we should set the configuration options
in alpabetical order.
5. In the ARM, in the backports we have added "(stale)" between
"cached" and "RRset" to make more clear a stale RRset may be
returned in this scenario.
(cherry picked from commit 104b676235)
Using "stale-answer-client-timeout" turns out to have unforeseen
negative consequences, and thus it is better to disable the feature
by default for the time being.
(cherry picked from commit e443279bbf)
Commit 9fb6d11abb (which converted BIND 9
documentation from DocBook to Sphinx) inadvertently removed a paragraph
from the description of the "max-ixfr-ratio" option. Add the missing
paragraph back.
(cherry picked from commit 3878cf4ac5)
Add a new option 'purge-keys' to 'dnssec-policy' that will purge key
files for deleted keys. The option determines how long key files
should be retained prior to removing the corresponding files from
disk.
If set to 0, the option is disabled and 'named' will not remove key
files from disk.
(cherry picked from commit 313de3a7e2)
When sphinx-build is invoked without the -d command line switch, the
default path to the directory in which cached environment and doctree
files are placed is OUTPUTDIR/.doctrees. This causes the contents of
such cache directories to needlessly be included in BIND release
directories. Avoid that by employing the -d command line switch to make
each sphinx-build process use a cache directory outside the output
directory. Make sure these cache directories are separate from each
other as well, to prevent multiple sphinx-build processes running in
parallel from interfering with each other.
In order to prevent documentation building issues from being glossed
over, pass the -W command line switch to all sphinx-build invocations.
This causes the latter to return with a non-zero exit code whenever any
Sphinx warnings are triggered.
(cherry picked from commit 51479ed9a3)
as "type primary" is preferred over "type master" now, it makes
sense to make "primaries" available as a synonym too.
added a correctness check to ensure "primaries" and "masters"
cannot both be used in the same zone.
(cherry picked from commit 16e14353b1)
The DNS Flag Day 2020 reduced all the EDNS buffer sizes to 1232. In
this commit, we revert the default value for nocookie-udp-size back to
4096 because the option is too obscure and most people don't realize
that they also need to change this configuration option in addition to
max-udp-size.
