BIND 9.12.0 is a new feature release of BIND, still under development.
|
|
|
|
|
|
This document summarizes new features and functional changes that
|
|
|
|
|
|
have been introduced on this branch. With each development
|
|
|
|
|
|
release leading up to the final BIND 9.12.0 release, this document
|
|
|
|
|
|
will be updated with additional features added and bugs fixed.

With the release of BIND 9.11.0, ISC changed to the open
|
|
|
|
|
|
source license for BIND from the ISC license to the Mozilla
|
|
|
|
|
|
Public License (MPL 2.0).
|
|
|
|
|
|
</p>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
The MPL-2.0 license requires that if you make changes to
|
|
|
|
|
|
licensed software (e.g. BIND) and distribute them outside
|
|
|
|
|
|
your organization, that you publish those changes under that
|
|
|
|
|
|
same license. It does not require that you publish or disclose
|
|
|
|
|
|
anything other than the changes you made to our software.
|
|
|
|
|
|
</p>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
This requirement will not affect anyone who is using BIND
|
|
|
|
|
|
without redistributing it, nor anyone redistributing it without
|
|
|
|
|
|
changes, therefore this change will be without consequence
|
|
|
|
|
|
for most individuals and organizations who are using BIND.
|
|
|
|
|
|
</p>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
Those unsure whether or not the license change affects their
|
|
|
|
|
|
use of BIND, or who wish to discuss how to comply with the
|
|
|
|
|
|
license may contact ISC at <a class="link" href="https://www.isc.org/mission/contact/" target="_top">

As of BIND 9.11.2, Windows XP is no longer a supported platform for

<span class="command"><strong>query_find()</strong></span> has been split into

Code implementing name server query processing has been moved

|
|
|
from <span class="command"><strong>named</strong></span> to an external library,
|
|
|
|
|
|
<span class="command"><strong>libns</strong></span>. This will make it easier to

write unit tests for the code, or to link it into new tools.

<span class="command"><strong>named</strong></span> can now synthesize negative responses
|
|
|
|
|
|
(NXDOMAIN, NODATA, or wildcard answers) from cached DNSSEC-verified
|
|
|
|
|
|
records that were returned in negative or wildcard responses from
|

authoritative servers.

<p>

This will reduce query loads on authoritative servers for signed
|
|
|
|
|
|
domains: when existing cached records can be used by the resolver
|
|
|
|
|
|
to determine that a name does not exist in the authorittive domain,
|
|
|
|
|
|
no query needs to be sent. Reducing the number of iterative queries
|
|
|
|
|
|
should also improve resolver performance.

This behavior is controlled by the new

<code class="filename">named.conf</code> option

<span class="command"><strong>synth-from-dnssec</strong></span>. It is enabled by

Support for zones signed using NSEC3 (without opt-out) is

planned for the future.

The DNS Response Policy Service (DNSRPS) API, a mechanism to
|
|
|
|
|
|
allow <span class="command"><strong>named</strong></span> to use an external response policy
|
|
|
|
|
|
provider, is now supported. (One example of such a provider is
|
|
|
|
|
|
"FastRPZ" from Farsight Security, Inc.) This allows the same
|
|
|
|
|
|
types of policy filtering as standard RPZ, but can reduce the
|
|
|
|
|
|
workload for <span class="command"><strong>named</strong></span>, particularly when using
|
|
|
|
|
|
large and frequently-updated policy zones. It also enables
|
|
|
|
|
|
<span class="command"><strong>named</strong></span> to share response policy providers
|
|
|
|
|
|
with other DNS implementations such as Unbound.

|
|
|
|

This feature is avaiable if BIND is built with
|
|
|
|
|
|
<span class="command"><strong>configure --enable-dnsrps</strong></span>, if a DNSRPS
|
|
|
|
|
|
provider is installed, and if <span class="command"><strong>dnsrps-enable</strong></span>
|
|
|
|
|
|
is set to "yes" in <code class="filename">named.conf</code>. Standard
|
|
|
|
|
|
built-in RPZ is used otherwise.

By default, BIND now uses the random number generation functions
|
|
|
|
|
|
in the cryptographic library (i.e., OpenSSL or a PKCS#11
|
|
|
|
|
|
provider) as a source of high-quality randomness rather than
|
|
|
|
|
|
<code class="filename">/dev/random</code>. This is suitable for virtual
|
|
|
|
|
|
machine environments, which may have limited entropy pools and
|
|
|
|
|
|
lack hardware random number generators.
|
|
|
|
|
|
</p>
|
|
|
|
|
|
<p>
|
|
|
|
|
|
This can be overridden by specifying another entropy source via
|
|
|
|
|
|
the <span class="command"><strong>random-device</strong></span> option in
|
|
|
|
|
|
<code class="filename">named.conf</code>, or via the <span class="command"><strong>-r</strong></span>
|
|
|
|
|
|
command line option. However, for functions requiring full
|
|
|
|
|
|
cryptographic strength, such as DNSSEC key generation, this
|
|
|
|
|
|
<span class="emphasis"><em>cannot</em></span> be overridden. In particular, the
|
|
|
|
|
|
<span class="command"><strong>-r</strong></span> command line option no longer has any
|

effect on <span class="command"><strong>dnssec-keygen</strong></span>.

|
|
|
|
|
</p>
|
|
|
|

<p>

This can be disabled by building with

|
|
|
|
|
<span class="command"><strong>configure --disable-crypto-rand</strong></span>, in which
|
|
|
|
|

entropy source. [RT #31459] [RT #46047]
