rndc addzone error reporting improvements
Clearer error messages from rndc addzone and modzone when the view is not
known or when allow-new-zones is off.
Also, remove a spurious newline from the delzone response.
4161. [test] Add JSON test for traffic size stats; also test
for consistency between "rndc stats" and the XML
and JSON statistics channel contents. [RT #38700]
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.
See the ARM for details of these options. [RT #37125]
4156. [func] Added statistics counters to track the sizes
of incoming queries and outgoing responses in
histogram buckets, as specified in RSSAC002.
[RT #39049]
response when there is a malformed EDNS option.
[RT #39647]
4153. [bug] Dig should zero non significant +subnet bits. Check
that non significant ECS bits are zero on receipt.
[RT #39647]
experimental SIT option of BIND 9.10. The following
named.conf directives are avaliable: send-cookie,
cookie-secret, cookie-algorithm and nocookie-udp-size.
The following dig options are available:
+[no]cookie[=value] and +[no]badcookie. [RT #39928]
