      Updated CHANGES note to include require-server-cookie: · c631ff56
      Mark Andrews authored
      4152.   [func]          Implement DNS COOKIE option.  This replaces the
                              experimental SIT option of BIND 9.10.  The following
                              named.conf directives are available: send-cookie,
                              cookie-secret, cookie-algorithm, nocookie-udp-size
                              and require-server-cookie.  The following dig options
                              are available: +[no]cookie[=value] and +[no]badcookie.

      [master] DDoS mitigation features · 1479200a
      Evan Hunt authored
      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
      			- New stats counters have been added to count
      			  queries spilled due to these quotas.
      			See the ARM for details of these options. [RT #37125]

      [master] add "lock-file" and fix up singleton code · 7ae96d88
      Evan Hunt authored
      4080.	[func]		Completed change #4022, adding a "lock-file" option
      			to named.conf to override the default lock file,
      			in addition to the "named -X <filename>" command
      			line option.  Setting the lock file to "none"

      4040.	[func]		Added server-side support for pipelined TCP

      			the first query received from a client. (The new

      			specified for which the old behavior will still be

      [master] limit recursion depth and iterative queries · 3230429e
      Evan Hunt authored
      4006.	[security]	A flaw in delegation handling could be exploited
      			to put named into an infinite loop.  This has
      			been addressed by placing limits on the number
      			of levels of recursion named will allow (default 7),
      			and the number of iterative queries that it will
      			send (default 50) before terminating a recursive
      			query (CVE-2014-8500).
      			The recursion depth limit is configured via the
      			"max-recursion-depth" option.  [RT #35780]

      [master] servfail cache · a8783019
      Evan Hunt authored
      3943.	[func]		SERVFAIL responses can now be cached for a
      			limited time (configured by "servfail-ttl",
      			default 10 seconds, limit 30). This can reduce
      			the frequency of retries when an authoritative
      			server is known to be failing, e.g., due to
      			ongoing DNSSEC validation problems. [RT #21347]

      [master] ECS authoritative support · d46855ca
      Evan Hunt authored
      3936.	[func]		Added authoritative support for the EDNS Client
      			Subnet (ECS) option.
      			ACLs can now include "ecs" elements which specify
      			an address or network prefix; if an ECS option is
      			included in a DNS query, then the address encoded
      			in the option will be matched against "ecs" ACL
      			Also, if an ECS address is included in a query,
      			then it will be used instead of the client source
      			address when matching "geoip" ACL elements.  This
      			behavior can be overridden with "geoip-use-ecs no;".
      			When "ecs" or "geoip" ACL elements are used to
      			select a view for a query, the response will include
      			an ECS option to indicate which client network the
      			answer is valid for.

      3882.	[func]		By default, negative trust anchors will be tested
      			periodically to see whether data below them can be
      			validated, and if so, they will be allowed to
      			expire early. The "rndc nta -force" option
      			overrides this behvaior.  The default NTA lifetime
      			and the recheck frequency can be configured by the

      3746.	[func]		New "max-zone-ttl" option enforces maximum

      			named to use case-insensitive compression
      			(disabling change #3645) for specified
      			clients. (This is useful when dealing
      			with broken client implementations that
      			use case-sensitive name comparisons,
      			rejecting responses that fail to match the
      			capitalization of the query that was sent.)
