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]
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]
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]
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]
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]
3851. [func] Allow libseccomp based system-call filtering
on Linux; use "configure --enable-seccomp" to
turn it on. Thanks to Loganaden Velvindron for
the contribution. [RT #35347]
3832. [func] "named -L <filename>" causes named to send log
messages to the specified file by default instead
of to the system log. (Thanks to Tony Finch.)
[RT #35845]
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]
(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]
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]
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>.

3327. [func] Added 'filter-aaaa-on-v6' option; this is similar
to 'filter-aaaa-on-v4' but applies to IPv6

count. [RT #27009]

2988. [experimental] Added a "dlopen" DLZ driver, allowing the creation
of external DLZ drivers that can be loaded as
shared objects at runtime rather than linked with
named. Currently this is switched on via a
compile-time option, "configure --with-dlz-dlopen".
Note: the syntax for configuring DLZ zones
is likely to be refined in future releases.

2987. [func] Improve ease of configuring TKEY/GSS updates by
adding a "tkey-gssapi-keytab" option. If set,
updates will be allowed with any key matching
a principal in the specified keytab file.
"tkey-gssapi-credential" is no longer required
and is expected to be deprecated. (Contributed
