125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington BIND 9.11.0 includes a number of changes from BIND 9.10 and earlier
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington releases. New features include:
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - The EDNS EXPIRE option has been implemented on the client
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington side, allowing a slave server to set the expiration timer
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington correctly when transferring zone data from another slave
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington server.
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - A new "masterfile-style" zone option controls the formatting
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley of text zone files: When set to "full", a zone file is dumped
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington in single-line-per-record format.
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - "dig" now supports sending arbitary EDNS options by specifying
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington them on the command line.
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - "dig +ttlunits" causes dig to print TTL values with time-unit
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington suffixes: w, d, h, m, s for weeks, days, hours, minutes, and
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington seconds.
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - "serial-update-format" can now be set to "date". On update,
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington the serial number will be set to the current date in YYYYMMDDNN
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington format.
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - "dnssec-signzone -N date" sets the serial number to YYYYMMDDNN.
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - "named -L <filename>" causes named to send log messages to
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington the specified file by default instead of to the system log.

125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley BIND 9.10.0 includes a number of changes from BIND 9.9 and earlier
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley releases. New features include:
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley - DNS Response-rate limiting (DNS RRL), which blunts the
308c7ad5f68301d19f023af616f62f3e7cbce632Andreas Gustafsson impact of reflection and amplification attacks, is always
04b8111f2137a9cf9b0b71228f76b3e40ffa1173Brian Wellington compiled in and no longer requires a compile-time option
04b8111f2137a9cf9b0b71228f76b3e40ffa1173Brian Wellington to enable it.
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington - An experimental "Source Identity Token" (SIT) EDNS option
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington is now available. Similar to DNS Cookies as invented by
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington Donald Eastlake 3rd, these are designed to enable clients
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington to detect off-path spoofed responses, and to enable servers
ccad3c9ecbe8a1060ff7b407a318ccd592de536eBrian Wellington to detect spoofed-source queries. Servers can be configured
8224be5129daebea8f0f5e8be5f925679ec893f1Brian Wellington to send smaller responses to clients that have not identified
8224be5129daebea8f0f5e8be5f925679ec893f1Brian Wellington themselves using a SIT option, reducing the effectiveness of
870288a1fadd31edeb5f04660533bbca2fa62520Bob Halley amplification attacks. RRL processing has also been updated;
d14b749789121d9d502fa1348e9e73270e9b039fBob Halley clients proven to be legitimate via SIT are not subject to
63d1ef9e771b748ca9bf241dfc1f07d3730203faBob Halley rate limiting. Use "configure --enable-sit" to enable this
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley feature in BIND.
63d1ef9e771b748ca9bf241dfc1f07d3730203faBob Halley - A new zone file format, "map", stores zone data in a
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley format that can be mapped directly into memory, allowing
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley significantly faster zone loading.
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley - "delv" (domain entity lookup and validation) is a new tool
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley with dig-like semantics for looking up DNS data and performing
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley internal DNSSEC validation. This allows easy validation in
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley environments where the resolver may not be trustworthy, and
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley assists with troubleshooting of DNSSEC problems. (NOTE:
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley In previous development releases of BIND 9.10, this utility
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley was called "delve". The spelling has been changed to avoid
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley confusion with the "delve" utility included with the Xapian
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley search engine.)
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley - Improved EDNS(0) processing for better resolver performance
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley and reliability over slow or lossy connections.
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley - A new "configure --with-tuning=large" option tunes certain
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley compiled-in constants and default settings to values better
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley suited to large servers with abundant memory. This can
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley improve performance on such servers, but will consume more
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley memory and may degrade performance on smaller systems.
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley - Substantial improvement in response-policy zone (RPZ)
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley performance. Up to 32 response-policy zones can be
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley configured with minimal performance loss.
125d72976ab6b8fa6629a5ace276a86e9fef91acBrian Wellington - To improve recursive resolver performance, cache records
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley which are still being requested by clients can now be
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley automatically refreshed from the authoritative server
c50fd34a4e0e6978f8ca5f6f3ad8545549c3cfeeBob Halley before they expire, reducing or eliminating the time
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley window in which no answer is available in the cache.
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley - New "rpz-client-ip" triggers and drop policies allowing
25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley response policies based on the IP address of the client.
c50fd34a4e0e6978f8ca5f6f3ad8545549c3cfeeBob Halley - ACLs can now be specified based on geographic location
904a5734375869ffb504ed8cde6b68cafadb6d64Bob Halley using the MaxMind GeoIP databases. Use "configure
904a5734375869ffb504ed8cde6b68cafadb6d64Bob Halley --with-geoip" to enable.
c50fd34a4e0e6978f8ca5f6f3ad8545549c3cfeeBob Halley - Zone data can now be shared between views, allowing
multiple views to serve the same zones authoritatively
without storing multiple copies in memory.
- New XML schema (version 3) for the statistics channel
includes many new statistics and uses a flattened XML tree
for faster parsing. The older schema is now deprecated.
- A new stylesheet, based on the Google Charts API, displays
XML statistics in charts and graphs on javascript-enabled
browsers.
- The statistics channel can now provide data in JSON
format as well as XML.
- New stats counters track TCP and UDP queries received
per zone, and EDNS options received in total.
- The internal and export versions of the BIND libraries
(libisc, libdns, etc) have been unified so that external
library clients can use the same libraries as BIND itself.
- A new compile-time option, "configure --enable-native-pkcs11",
allows BIND 9 cryptography functions to use the PKCS#11 API
natively, so that BIND can drive a cryptographic hardware
service module (HSM) directly instead of using a modified
OpenSSL as an intermediary. (Note: This feature requires an
HSM to have a full implementation of the PKCS#11 API; many
current HSMs only have partial implementations. The new
"pkcs11-tokens" command can be used to check API completeness.
Native PKCS#11 is known to work with the Thales nShield HSM
and with SoftHSM version 2 from the Open DNSSEC project.)
- The new "max-zone-ttl" option enforces maximum TTLs for
zones. This can simplify the process of rolling DNSSEC keys
by guaranteeing that cached signatures will have expired
within the specified amount of time.
- "dig +subnet" sends an EDNS CLIENT-SUBNET option when
querying.
- "dig +expire" sends an EDNS EXPIRE option when querying.
When this option is sent with an SOA query to a server
that supports it, it will report the expiry time of
a slave zone.
- New "dnssec-coverage" tool to check DNSSEC key coverage
for a zone and report if a lapse in signing coverage has
been inadvertently scheduled.
- Signing algorithm flexibility and other improvements
for the "rndc" control channel.
- "named-checkzone" and "named-compilezone" can now read
journal files, allowing them to process dynamic zones.
- Multiple DLZ databases can now be configured. Individual
zones can be configured to be served from a specific DLZ
database. DLZ databases now serve zones of type "master"
and "redirect".
- "rndc zonestatus" reports information about a specified zone.
- "named" now listens on IPv6 as well as IPv4 interfaces
by default.
- "named" now preserves the capitalization of names
when responding to queries: for instance, a query for
"example.com" may be answered with "example.COM" if the
name was configured that way in the zone file. Some
clients have a bug causing them to depend on the older
behavior, in which the case of the answer always matched
the case of the query, rather than the case of the name
configured in the DNS. Such clients can now be specified
in the new "no-case-compress" ACL; this will restore the
older behavior of "named" for those clients only.
- new "dnssec-importkey" command allows the use of offline
DNSSEC keys with automatic DNSKEY management.
- New "named-rrchecker" tool to verify the syntactic
correctness of individual resource records.
- When re-signing a zone, the new "dnssec-signzone -Q" option
drops signatures from keys that are still published but are
no longer active.
- "named-checkconf -px" will print the contents of configuration
files with the shared secrets obscured, making it easier to
share configuration (e.g. when submitting a bug report)
without revealing private information.
- "rndc scan" causes named to re-scan network interfaces for
changes in local addresses.
- On operating systems with support for routing sockets,
network interfaces are re-scanned automatically whenever
they change.
- "tsig-keygen" is now available as an alternate command
name to use for "ddns-confgen".
Building

Several environment variables that can be set before running
configure will affect compilation:
CC
The C compiler to use. configure tries to figure
out the right one for supported systems.
CFLAGS
C compiler flags. Defaults to include -g and/or -O2
as supported by the compiler. Please include '-g'
if you need to set CFLAGS.
STD_CINCLUDES
System header file directories. Can be used to specify
where add-on thread or IPv6 support is, for example.
Defaults to empty string.
STD_CDEFINES
Any additional preprocessor symbols you want defined.
Defaults to empty string.
Possible settings:
Change the default syslog facility of named/lwresd.
-DISC_FACILITY=LOG_LOCAL0

On most platforms, BIND 9 is built with multithreading
support, allowing it to take advantage of multiple CPUs.
You can configure this by specifying "--enable-threads" or
"--disable-threads" on the configure command line. The default
is to enable threads, except on some older operating systems
on which threads are known to have had problems in the past.
(Note: Prior to BIND 9.10, the default was to disable threads on
Linux systems; this has been reversed. On Linux systems, the
threaded build is known to change BIND's behavior with respect
to file permissions; it may be necessary to specify a user with
the -u option when running named.)
To build shared libraries, specify "--with-libtool" on the
configure command line.
Certain compiled-in constants and default settings can be
increased to values better suited to large servers with abundant
memory resources (e.g, 64-bit servers with 12G or more of memory)
by specifying "--with-tuning=large" on the configure command
line. This can improve performance on big servers, but will
consume more memory and may degrade performance on smaller
systems.
For the server to support DNSSEC, you need to build it
with crypto support. You must have OpenSSL 0.9.5a
or newer installed and specify "--with-openssl" on the
configure command line. If OpenSSL is installed under
a nonstandard prefix, you can tell configure where to
look for it using "--with-openssl=/prefix".
To support the HTTP statistics channel, the server must
be linked with at least one of the following: libxml2
(http://xmlsoft.org) or json-c (https://github.com/json-c).
If these are installed at a nonstandard prefix, use
"--with-libxml2=/prefix" or "--with-libjson=/prefix".
On some platforms it is necessary to explicitly request large
file support to handle files bigger than 2GB. This can be
done by "--enable-largefile" on the configure command line.
Support for the "fixed" rrset-order option can be enabled
or disabled by specifying "--enable-fixed-rrset" or
"--disable-fixed-rrset" on the configure command line.
The default is "disabled", to reduce memory footprint.
If your operating system has integrated support for IPv6, it
will be used automatically. If you have installed KAME IPv6
separately, use "--with-kame[=PATH]" to specify its location.
"make install" will install "named" and the various BIND 9 libraries.
By default, installation is into /usr/local, but this can be changed
with the "--prefix" option when running "configure".
You may specify the option "--sysconfdir" to set the directory
where configuration files like "named.conf" go by default,
and "--localstatedir" to set the default parent directory
of "run/named.pid". For backwards compatibility with BIND 8,
--sysconfdir defaults to "/etc" and --localstatedir defaults to
"/var" if no --prefix option is given. If there is a --prefix
option, sysconfdir defaults to "$prefix/etc" and localstatedir
defaults to "$prefix/var".
To see additional configure options, run "configure --help".
Note that the help message does not reflect the BIND 8
compatibility defaults for sysconfdir and localstatedir.
If you're planning on making changes to the BIND 9 source, you
should also "make depend". If you're using Emacs, you might find
"make tags" helpful.
If you need to re-run configure please run "make distclean" first.
This will ensure that all the option changes take.
Building with gcc is not supported, unless gcc is the vendor's usual
compiler (e.g. the various BSD systems, Linux).
Known compiler issues:
* gcc-3.2.1 and gcc-3.1.1 is known to cause problems with solaris-x86.
* gcc prior to gcc-3.2.3 ultrasparc generates incorrect code at -02.
* gcc-3.3.5 powerpc generates incorrect code at -02.
* Irix, MipsPRO 7.4.1m is known to cause problems.
A limited test suite can be run with "make test". Many of
the tests require you to configure a set of virtual IP addresses
on your system, and some require Perl; see bin/tests/system/README
for details.
SunOS 4 requires "printf" to be installed to make the shared
libraries. sh-utils-1.16 provides a "printf" which compiles
on SunOS 4.
Known limitations
Linux requires kernel build 2.6.39 or later to get the
performance benefits from using multiple sockets.
Documentation
The BIND 9 Administrator Reference Manual is included with the
source distribution in DocBook XML and HTML format, in the
doc/arm directory.
Some of the programs in the BIND 9 distribution have man pages
in their directories. In particular, the command line
options of "named" are documented in /bin/named/named.8.
There is now also a set of man pages for the lwres library.
If you are upgrading from BIND 8, please read the migration
notes in doc/misc/migration. If you are upgrading from
BIND 4, read doc/misc/migration-4to9.
Frequently asked questions and their answers can be found in
FAQ.
Additional information on various subjects can be found
in the other README files.
Change Log
A detailed list of all changes to BIND 9 is included in the
file CHANGES, with the most recent changes listed first.
Change notes include tags indicating the category of the
change that was made; these categories are:
[func] New feature
[bug] General bug fix
[security] Fix for a significant security flaw
[experimental] Used for new features when the syntax
or other aspects of the design are still
in flux and may change
[port] Portability enhancement
[maint] Updates to built-in data such as root
server addresses and keys
[tuning] Changes to built-in configuration defaults
and constants to improve performance
[protocol] Updates to the DNS protocol such as new
RR types
[test] Changes to the automatic tests, not
affecting server functionality
[cleanup] Minor corrections and refactoring
[doc] Documentation
[contrib] Changes to the contributed tools and
libraries in the 'contrib' subdirectory
[placeholder] Used in the master development branch to
reserve change numbers for use in other
branches, e.g. when fixing a bug that only
exists in older releases
In general, [func] and [experimental] tags will only appear
in new-feature releases (i.e., those with version numbers
ending in zero). Some new functionality may be backported to
older releases on a case-by-case basis. All other change
types may be applied to all currently-supported releases.
