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]
startup-notify-rate instead of serial-query-rate.
[RT #24454]
3955. [bug] Notify messages due to changes are no longer queued
behind startup notify messages. [RT #24454]
EDNS(1) queries (define DRAFT_ANDREWS_EDNS1 when
building). Add support for limiting the EDNS version
advertised to servers: server { edns-version 0; };
Log the EDNS version received in the query log.
[RT #35864]
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]
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.
(Thanks to Vincent Bernat.) [RT #36781]
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
"nta-lifetime" and "nta-recheck" options. [RT #36146]
3852. [func] Increase the default number of clients available
for servicing lightweight resolver queries, and
make them configurable via the "lwres-tasks" and
"lwres-clients" options. (Thanks to Tomas Hozza.)
[RT #35857]
3814. [func] The "masterfile-style" zone option controls the
formatting of dumped zone files. Options are
"relative" (multiline format) and "full" (one
record per line). The default is "relative".
[RT #20798]
3811. [func] "serial-update-method date;" sets serial number
on dynamic update to today's date in YYYYMMDDNN
format. (Thanks to Bradley Forschinger.) [RT #24903]
3746. [func] New "max-zone-ttl" option enforces maximum
TTLs for zones. If loading a zone containing a
higher TTL, the load fails. DDNS updates with
higher TTLs are accepted but the TTL is truncated.
(Note: Currently supported for master zones only;
inline-signing slaves will be added.) [RT #38405]
(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]
information will be automatically updated if the
OS supports routing sockets. Use
"automatic-interface-scan no;" to disable.
Add "rndc scan" to trigger a scan. [RT #23027]
3731. [func] Added a "no-case-compress" ACL, which causes
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.)
[RT #35300]
3620. [func] Added "rpz-client-ip" policy triggers, enabling
RPZ responses to be configured on the basis of
the client IP address; this can be used, for
example, to blacklist misbehaving recursive
or stub resolvers. [RT #33605]
3619. [bug] Fixed a bug in RPZ with "recursive-only no;"
[RT #33776]
3535. [func] Add support for setting Differentiated Services Code
Point (DSCP) values in named. Most configuration
options which take a "port" option (e.g.,
listen-on, forwarders, also-notify, masters,
notify-source, etc) can now also take a "dscp"
option specifying a code point for use with
outgoing traffic, if supported by the underlying
OS. [RT #27596]
3504. [func] Add support for ACLs based on geographic location,
using MaxMind GeoIP databases. Based on code
contributed by Ken Brownfield <kb@slide.com>.
[RT #30681]
3501. [func] zone-statistics now takes three options: full,
terse, and none. "yes" and "no" are retained as
synonyms for full and terse, respectively. [RT #29165]
3432. [func] Multiple DLZ databases can now be configured.
DLZ databases are searched in the order configured,
unless set to "search no", in which case a
zone can be configured to be retrieved from a
particular DLZ database by using a "dlz <name>"
option in the zone statement. DLZ databases can
support type "master" and "redirect" zones.

Add
- optional "recursive-only yes|no" to the response-policy statement
- optional max-policy-ttl to limit the lies that "recursive-only no"
can introduce into resolvers' caches
- test that queries with RD=0 are not rewritten by default
- performance smoke test
Change encoding of PASSTHRU action to "rpz-passthru".
(The old encoding is still accepted.)
Fix rt26180 assert botch in zone_findrdataset() in this branch
as well.
Fix missing signatures on NOERROR results despite RPZ hits
when there are signatures and the client asks for DNSSEC,
3327. [func] Added 'filter-aaaa-on-v6' option; this is similar
to 'filter-aaaa-on-v4' but applies to IPv6
connections. (Use "configure --enable-filter-aaaa"
to enable this option.) [RT #27308]
