      [master] dnstap · b66b333f
      Evan Hunt authored
      4235.	[func]		Added support in named for "dnstap", a fast method of
      			capturing and logging DNS traffic, and a new command
      			"dnstap-read" to read a dnstap log file.  Use
      			"configure --enable-dnstap" to enable this
      			feature (note that this requires libprotobuf-c
      			and libfstrm). See the ARM for configuration details.
      
      			Thanks to Robert Edmonds of Farsight Security.

      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
      			  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]

      [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]

      			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

      [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
      			elements.
      
      			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.

      3744. [experimental] SIT: send and process Source Identity Tokens · b5f6271f
      Mark Andrews authored
                              (which are similar to DNS Cookies by Donald Eastlake)
                              and are designed to help clients detect off path
                              spoofed responses and for servers to detect legitimate
                              clients.
      
                              SIT use a experimental EDNS option code (65001).
      
                              SIT can be enabled via --enable-developer or
                              --enable-sit.  It is on by default in Windows.
      
                              RRL processing as been updated to know about SIT with
                              legitimate clients not being rate limited. [RT #35389]
