4269. [bug] Zones using "map" format master files currently
don't work as policy zones. This limitation has
now been documented; attempting to use such zones
in "response-policy" statements is now a
configuration error. [RT #38321]
This is for ticket #36955.
Improve grammar for zone-statistics to list new arguments.
Refer to the docs in the options section.
Clarify about stats may not show view name.
This is for ticket #39570.
I didn't have this reviewed for v9_10, but was reviewed for the
master but had different option names.
Moved some docs from server statement to options.
While there add a missing related option from grammar.
Also improved docs a little for nosit-udp-size.
Note I didn't add a changelog entry. The documentation was already
there and only modified a little.
dblatex generated LaTeX that failed with the "id" for link reference
in the sect1 when itr had no <title> to reference.
(A workaround is to set a <title>.)
But since this appendix only had one section
and looked off to have B1 with no title and no B2, just remove the
sect1 tags.
I added the id to the first <para> tag just in case someone uses
it to link.
Note I didn't reformat the content there.
I didn't get this reviewed as was trivial change.
3938. [func] Added quotas to be used in recursive resolvers
that are under high query load for names in zones
whose authoritative servers are nonresponsive or
are experiencing a denial of service attack.
- "fetches-per-server" limits the number of
simultaneous queries that can be sent to any
single authoritative server. The configured
value is a starting point; it is automatically
adjusted downward if the server is partially or
completely non-responsive. The algorithm used to
adjust the quota can be configured via the
"fetch-quota-params" option.
- "fetches-per-zone" limits the number of
simultaneous queries that can be sent for names
within a single domain. (Note: Unlike
"fetches-per-server", this value is not
self-tuning.)
- New stats counters have been added to count
queries spilled due to these quotas.
These options are not available by default;
use "configure --enable-fetchlimit" (or
--enable-developer) to include them in the build.
See the ARM for details of these options. [RT #37125]
4021. [bug] Adjust max-recursion-queries to accommodate
the need for more queries when the cache is
empty. [RT #38104]
(cherry picked from commit be7fba8019)
