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]

pass the correct name to query_prefetch
3829. [func] "dig +ttlunits" causes dig to print TTL values
with time-unit suffixes: w, d, h, m, s for
weeks, days, hours, minutes, and seconds. (Thanks
to Tony Finch.) [RT #35823]
3821. [contrib] Added a new "mysqldyn" DLZ module with dynamic
update and transaction support. Thanks to Marty
Lee for the contribution. [RT #35656]
3820. [func] The DLZ API doesn't pass the database version to
the lookup() function; this can cause DLZ modules
that allow dynamic updates to mishandle prerequisite
checks. This has been corrected by adding a
'dbversion' field to the dns_clientinfo_t
structure. [RT #35656]
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]
in draft-andrews-dnsext-expire-00. Retrivial of
remaining time to expiry from slave zones is supported.
EXPIRE uses an experimental option code (65002) and
is subject to change. [RT #35416]
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]
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]
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]
Install some include files:
dns/client.h
dns/tsec.h
irs/resconf.h
irs/types.h
(I noticed these when building DHCP using installed BIND9.)
This was okayed during the 2014-01-02 BIND9 phone meeting.
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]
3562. [func] Update map file header format to include a SHA-1 hash
of the database content, so that corrupted map files
can be rejected at load time. [RT #32459]
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]
3524. [func] Added an alternate statistics channel in JSON format,
when the server is built with the json-c library:
http://[address]:[port]/json. [RT #32630]
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]
- handle malformed answers from DLZ better:
- handle dlz_lookup errors better:
when the first lookup of a name returns an unexpected failure code,
we return it to the caller rather than continuing on to look up
the wildcard. we now only continue processing if the return from
the first lookup was either ISC_R_SUCCESS or ISC_R_NOTFOUND.
- improved backward-compatibility for dlz_version:
added a DLZ_DLOPEN_AGE value indicating how many versions
back from the current DLZ_DLOPEN_VERSION named will support

'"\#"' was incorrectly being treated as a unknown data escape sequence.
3434. [bug] Pass client info to the DLZ findzone() entry
point in addition to lookup(). This makes it
possible for a database to answer differently
whether it's authoritative for a name depending
on the address of the client. [RT #31775]
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.
[RT #27597]
adds query type statistics at the zone level, and
flattens the XML tree and uses compressed format to
optimize parsing. Includes new XSL that permits
charting via the Google Charts API on browsers that
support javascript in XSL. The old XML schema has been
deprecated. [RT #30023]

and more from CVS
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,
3329. [bug] Handle RRSIG signer-name case consistently: We
generate RRSIG records with the signer-name in
lower case. We accept them with any case, but if
they fail to validate, we try again in lower case.
[RT #27451]
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.
- multiple DLZ's can be specified, including multiple DLZ's using
the same driver; e.g., two different back-ends both loaded by the
dlopen driver
- new "search" option can be specified in a DLZ indicating whether
this DLZ database should be searched for unknown zones. The
default is "yes". If "no", then the zone can only be found by
named if it's registered in the zone table, which happens if the
zone is configured for dynamic updates, or if "dlz <dlzname>" is
specified in the zone statement. (The latter functionality is
incomplete in this commit).
fix possible memory overrun in dns_zone_getincludes
fix inconsistent mxtc use in ns_server_zonestatus
fix missing out of memory errors checks in zone_registerinclude
fix possible use after free issues zone_registerinclude/ns_server_zonestatus
include the serial number of the zone from which
they were generated, if different (as in the case
of inline-signing zones). This is to be used in
inline-signing zones, to track changes between the
unsigned and signed versions of the zone, which may
have different serial numbers.
(Note: raw zonefiles generated by this version of
BIND are no longer compatble with prior versions.
To generate a backward-compatible raw zonefile
using dnssec-signzone or named-compilezone, specify
output format "raw=0" instead of simply "raw".)
