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.

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.
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]
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]
4124. [func] Log errors or warnings encountered when parsing the
internal default configuration. Clarify the logging
of errors and warnings encountered in rndc
addzone or modzone parameters. [RT #39440]
4120. [bug] A bug in RPZ could cause the server to crash if
policy zones were updated while recursion was
pending for RPZ processing of an active query.
[RT #39415]
4083. [cleanup] Print of the number of CPUs and UDP listeners
in the log and in "rndc status" output; indicate
whether threads are supported in "named -V" output.
[RT #38811]
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"
using either method disables the check completely.
[RT #37908]
4056. [bug] Expanded automatic testing of trust anchor
management and fixed several small bugs including
a memory leak and a possible loss of key state
information. [RT #38458]
4055. [func] "rndc managed-keys" can be used to check status
of trust anchors or to force keys to be refreshed,
Also, the managed keys data file has easier-to-read
comments. [RT #38458]
4040. [func] Added server-side support for pipelined TCP
queries. TCP connections are no longer closed after
the first query received from a client. (The new
"keep-response-order" option allows clients to be
specified for which the old behavior will still be
used.) [RT #37821]
Based on a patch sent in by Tony Finch <dot@dotat.at>.
Also fix win32 implementation of isc_file_openunique() to use a random
filename instead of using the process id.
4034. [func] When added, negative trust anchors (NTA) are now
saved to files (viewname.nta), in order to
persist across restarts of the named server.
[RT #37087]
4030. [func] "rndc delzone" is now applicable to zones that were
configured in named.conf, as well as zones that
were added via "rndc addzone". (Note, however, that
if named.conf is not also modified, the deleted zone
will return when named is reloaded.) [RT #37887]
4029. [func] "rndc showzone" displays the current configuration
of a specified zone. [RT #37887]
Conflicts:
bin/tests/system/conf.sh.in
lib/dns/win32/libdns.def.in
lib/isc/win32/file.c
The merge also needed to update files in legacy and tcp system tests
(newly introduced in master after branch was created) to introduce use
of lockfile.
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]
4005. [func] The buffer used for returning text from rndc
commands is now dynamically resizable, allowing
arbitrarily large amounts of text to be sent back
to the client. (Prior to this change, it was
possible for the output of "rndc tsig-list" to be
truncated.) [RT #37731]
3999. [func] "mkeys" and "nzf" files are now named after
their corresponding views, unless the view name
contains characters that would be incompatible
with use in a filename (i.e., slash, backslash,
or capital letters). If a view name does contain
these characters, the files will still be named
using a cryptographic hash of the view name.
Regardless of this, if a file using the old name
format is found to exist, it will continue to be
used. [RT #37704]
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]
3867. [func] "rndc nta" can now be used to set a temporary
negative trust anchor, which disables DNSSEC
validation below a specified name for a specified
period of time (not exceeding 24 hours). This
can be used when validation for a domain is known
to be failing due to a configuration error on
the part of the domain owner rather than a
spoofing attack. [RT #29358]
3784. [bug] Using "rrset-order fixed" when it had not been
enabled at compile time caused inconsistent
results. It now works as documented, defaulting
to cyclic mode. [RT #28104]
3745. [func] "configure --with-tuning=large" adjusts various
compiled-in constants and default settings to
values suited to large servers with abundant
memory. [RT #29538]
(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]
3741. [func] "delve" (domain entity lookup and validation engine):
A new tool with dig-like semantics for performing DNS
lookups, with internal DNSSEC validation, using the
same resolver and validator logic as named. This
allows easy validation of DNSSEC data in environments
with untrustworthy resolvers, and assists with
troubleshooting of DNSSEC problems. (Note: not yet
available on win32.) [RT #32406]
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]
3705. [func] "configure --enable-native-pkcs11" enables BIND
to use the PKCS#11 API for all cryptographic
functions, so that it can drive a hardware service
module directly without the need to use a modified
OpenSSL as intermediary (so long as the HSM's vendor
provides a complete-enough implementation of the
PKCS#11 interface). This has been tested successfully
with the Thales nShield HSM and with SoftHSMv2 from
the OpenDNSSEC project. [RT #29031]
3700. [func] Allow access to subgroups of XML statistics via
special URLs http://<server>:<port>/xml/v3/server,
/zones, /net, /tasks, /mem, and /status. [RT #35115]
3699. [bug] Improvements to statistics channel XSL stylesheet:
the stylesheet can now be cached by the browser;
section headers are omitted from the stats display
when there is no data in those sections to be
displayed; counters are now right-justified for
easier readability. [RT #35117]
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]
Updated CHANGES note:
3606. [func] "rndc flushtree" now flushes matching
records in the address database and bad cache
as well as the DNS cache. (Previously only the
DNS cache was flushed.) [RT #33970]
3606. [func] "rndc flushtree -all" flushes matching
records in the ADB and bad cache as well as
the DNS cache. (Without the "-all" option,
flushtree will still only flush records from
the DNS cache.) [RT #33970]
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]
3506. [func] When setting "max-cache-size" and "max-acache-size",
the keyword "unlimited" is no longer defined as equal
to 4 gigabytes (except on 32-bit platforms); it
means literally unlimited. [RT #32358]
3505. [bug] When setting "max-cache-size" and "max-acache-size",
larger values than 4 gigabytes could not be set
explicitly, though larger sizes were available
when setting cache size to 0. This has been
corrected; the full range is now available.
[RT #32358]
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]
report the files that were being used so they can
be cleaned up if desired. [RT #27899]

remove slave/stub files when deleting a zone using delzone
- rndc zonestatus now checks the signing time on the
signed, not raw, db when looking at inline-signing zones
3476. [bug] "rndc zonestatus" could report a spurious "not
found" error on inline-signing zones. [RT #29226]
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.

for rt26172
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]
This includes the following changes:
3326. [func] Added task list statistics: task model, worker
threads, quantum, tasks running, tasks ready.
[RT #27678]
3325. [func] Report cache statistics: memory use, number of
nodes, number of hash buckets, hit and miss counts.
[RT #27056]
3324. [test] Add better tests for ADB stats [RT #27057]
3323. [func] Report the number of buckets the resolver is using.
[RT #27020]
3322. [func] Monitor the number of active TCP and UDP dispatches.
[RT #27055]
3321. [func] Monitor the number of recursive fetches and the
number of open sockets, and report these values in
the statistics channel. [RT #27054]
3320. [func] Added support for monitoring of recursing client
count. [RT #27009]
3319. [func] Added support for monitoring of ADB entry count and
hash size. [RT #27057]
Added API to create a set of UDP dispatches which can be shared
round-robin style when making upstream queries for authoritative
data; this should reduce lock contention in the query source
dispatch.
