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.
+values better suited to small machines, e.g. OpenWRT boxes, by specifying
+--with-tuning=small on the configure command line. This will decrease
+memory usage by using smaller structures, but will degrade performance.
On Linux, process capabilities are managed in user space using the libcap
library, which can be installed on most Linux systems via the libcap-dev

<p>
The <span class="command"><strong>dnssec-policy</strong></span> statement defines a key and
signing policy (KASP) for zones.
</p>
<p>
- KASP is used to determine how one or more zones need to be signed
- with DNSSEC. For example, how often RRSIG records need to be
- refreshed, or what cryptographic algorithms to use.
+ A KASP determines how one or more zones will be signed
+ with DNSSEC. For example, it specifies how often keys should
+ roll, which cryptographic algorithms to use, and how often RRSIG
+ records need to be refreshed.
+ </p>
+ <p>
+ Multiple key and signing policies can be configured. To
+ attach a policy to a zone, add a <span class="command"><strong>dnssec-policy</strong></span>
+ option to the <span class="command"><strong>zone</strong></span> statement, specifying he
+ name of the policy that should be used.
+ </p>
+ <p>
+ Key rollover timing is computed for each key according to
+ the key lifetime defined in the KASP. The lifetime may be
+ modified by zone TTLs and propagation delays, in order to
+ prevent validation failures. When a key reaches the end of its
+ lifetime,
+ <span class="command"><strong>named</strong></span> will generate and publish a new key
+ automatically, then deactivate the old key and activate the
+ new one, and finally retire the old key according to a computed
+ schedule.
</p>
<p>
- You can configure multiple policies. To attach a policy to a zone
- simply add <strong class="userinput"><code>dnssec-policy "policy_name"</code></strong>
- option to the <span class="command"><strong>zone</strong></span> statement with a matching
- policy name.
+ Zone-signing key (ZSK) rollovers require no operator input.
+ Key-signing key (KSK) and combined signing key (CSK) rollovers
+ require action to be taken to submit a DS record to the parent.
+ Rollover timing for KSKs and CSKs is adjusted to take into account
+ delays in processing and propagating DS updates.
+ </p>
+ <p>
+ There are two predefined <span class="command"><strong>dnssec-policy</strong></span> names:
+ <span class="command"><strong>none</strong></span> and <span class="command"><strong>default</strong></span>.
+ Setting a zone's policy to
+ <span class="command"><strong>none</strong></span> is the same as not setting
+ <span class="command"><strong>dnssec-policy</strong></span> at all; the zone will not
+ be signed. Policy <span class="command"><strong>default</strong></span> causes the
+ zone to be signed with a single combined signing key (CSK)
+ using algorithm ECDSAP256SHA256; this key will have an
+ unlimited lifetime. (A verbose copy of this policy
+ may be found in the source tree, in the file
+ <code class="filename">doc/misc/dnssec-policy.default.conf</code>.)
+ </p>
+<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
+<h3 class="title">Note</h3>
+ The default signing policy may change in future releases.
+ This could result in changes to your signing policy
+ occurring when you upgrade to a new version of BIND. Check
+ the release notes carefully when upgrading to be informed
+ of such changes. To prevent policy changes on upgrade,
+ use an explicitly defined <span class="command"><strong>dnssec-policy</strong></span>
+ rather than <span class="command"><strong>default</strong></span>.
+ </div>
+<p>
+ </p>
+ <p>
+ If a <span class="command"><strong>dnssec-policy</strong></span> statement is modified
+ and the server restarted or reconfigured, <span class="command"><strong>named</strong></span>
+ will attempt to change the policy smoothly from the old one to
+ the new. For example, if the key algorithm is changed, then
+ a new key will be generated with the new algorithm, and the old
+ algorithm will be retired when the existing key's lifetime ends.
+ </p>

+ <span class="command"><strong>dnssec-policy</strong></span> statement:

- an example (for illustration purposes only) of some possible
- keys in a <span class="command"><strong>dnssec-policy</strong></span>:
+ A list specifying the algorithms and roles to use when

+ Entries in this list do not represent specific
+ DNSSEC keys, which may be changed on a regular basis,
+ but the roles that keys will play in the signing policy.
+ For example, configuring a KSK of algorithm RSASHA256 ensures
+ that the DNSKEY RRset will always include a key-signing key
+ for that algorithm.

+ list:

<p>
- This example lists three keys. The first token determines
- what RRsets the key will sign. If set to
- <strong class="userinput"><code>ksk</code></strong> the key will sign the DNSKEY, CDS,
- and CDNSKEY RRsets, if set to <strong class="userinput"><code>zsk</code></strong> the
- key will sign the other RRsets, and if set to
- <strong class="userinput"><code>csk</code></strong> the key will sign all RRsets.
+ This example specifies that three keys should be used
+ in the zone. The first token determines which role the
+ key will play in signing RRsets. If set to
+ <strong class="userinput"><code>ksk</code></strong>, then this will be
+ a key-signing key; it will have the KSK flag set and
+ will only be used to sign DNSKEY, CDS, and CDNSKEY RRsets.
+ If set to <strong class="userinput"><code>zsk</code></strong>, this will be
+ a zone-signing key; the KSK flag will be unset, and
+ the key will sign all RRsets <span class="emphasis"><em>except</em></span>
+ DNSKEY, CDS, and CDNSKEY. If set to
+ <strong class="userinput"><code>csk</code></strong> the key will have the KSK
+ flag set and will be used to sign all RRsets.

<p>
- The following part determines where the key will be stored.
- Currently keys can only be stored in the configured

</p>
<p>
- The third token tells how long the key may be used. In the

- key may be used for 30 days and the third key has a rather
- peculiar lifetime of 6 months, 12 hours, 3 minutes and 15
- seconds.
+ The <span class="command"><strong>lifetime</strong></span> parameter specifies how

+ lifetime, the second key may be used for 30 days, and the
+ third key has a rather peculiar lifetime of 6 months,

+ seconds is the same as <span class="command"><strong>unlimited</strong></span>.
</p>
<p>
- The last token(s) are the key's algorithm and algorithm
- length. The length may be omitted as shown in the
- example for the second and third key.
+ Note that the lifetime of a key may be extended if
+ retiring it too soon would cause validation failures.
+ For example, if the key were configured to roll more
+ frequently than its own TTL, its lifetime would
+ automatically be extended to account for this.
+ </p>
+ <p>
+ The <span class="command"><strong>algorithm</strong></span> parameter specifies
+ the key's algorithm, expressed either as a string
+ ("rsasha256", "ecdsa384", etc) or as a decimal number.
+ An optional second parameter specifies the key's size
+ in size in bits. If it is omitted, as shown in the
+ example for the second and third keys, an appropriate

-<a name="relnotes_versions"></a>Note on Version Numbering</h3></div></div></div>
<p>
- Until BIND 9.12, new feature development releases were tagged
- as "alpha" and "beta", leading up to the first stable release
- for a given development branch, which always ended in ".0".
- More recently, BIND adopted the "odd-unstable/even-stable"
- release numbering convention. There will be no "alpha" or "beta"
- releases in the 9.15 branch, only increasing version numbers.
- So, for example, what would previously have been called 9.15.0a1,
- 9.15.0a2, 9.15.0b1, and so on, will instead be called 9.15.0,
- 9.15.1, 9.15.2, etc.
- </p>
- <p>
- The first stable release from this development branch will be
- renamed as 9.16.0. Thereafter, maintenance releases will continue
- on the 9.16 branch, while unstable feature development proceeds in
- 9.17.
+ Please see the file <code class="filename">CHANGES</code> for a more
+ detailed list of changes and bug fixes.

-<a name="relnotes_versions"></a>Note on Version Numbering</h3></div></div></div>
<p>
- Until BIND 9.12, new feature development releases were tagged
- as "alpha" and "beta", leading up to the first stable release
- for a given development branch, which always ended in ".0".
- More recently, BIND adopted the "odd-unstable/even-stable"
- release numbering convention. There will be no "alpha" or "beta"
- releases in the 9.15 branch, only increasing version numbers.
- So, for example, what would previously have been called 9.15.0a1,
- 9.15.0a2, 9.15.0b1, and so on, will instead be called 9.15.0,
- 9.15.1, 9.15.2, etc.
- </p>
- <p>
- The first stable release from this development branch will be
- renamed as 9.16.0. Thereafter, maintenance releases will continue
- on the 9.16 branch, while unstable feature development proceeds in
- 9.17.
+ Please see the file <code class="filename">CHANGES</code> for a more
+ detailed list of changes and bug fixes.

-Release Notes for BIND Version 9.15.8
+Release Notes for BIND Version 9.17.0
Introduction
-BIND 9.15 is an unstable development release of BIND. This document
+BIND 9.17 is an unstable development release of BIND. This document
summarizes new features and functional changes that have been introduced
on this branch. With each development release leading up to the stable
-BIND 9.16 release, this document will be updated with additional features
+BIND 9.18 release, this document will be updated with additional features
added and bugs fixed.
-Note on Version Numbering
-
-Until BIND 9.12, new feature development releases were tagged as "alpha"
-and "beta", leading up to the first stable release for a given development
-branch, which always ended in ".0". More recently, BIND adopted the
-"odd-unstable/even-stable" release numbering convention. There will be no
-"alpha" or "beta" releases in the 9.15 branch, only increasing version
-numbers. So, for example, what would previously have been called 9.15.0a1,
-9.15.0a2, 9.15.0b1, and so on, will instead be called 9.15.0, 9.15.1,
-9.15.2, etc.
-
-The first stable release from this development branch will be renamed as
-9.16.0. Thereafter, maintenance releases will continue on the 9.16 branch,
-while unstable feature development proceeds in 9.17.
+Please see the file CHANGES for a more detailed list of changes and bug
+fixes.
Supported Platforms
each release, source code, and pre-compiled versions for Microsoft Windows
operating systems.
-Notes for BIND 9.15.8
-
-Feature Changes
-
- * The trust-anchors statement no longer rejects a mix of both key-style
- and DS-style trust anchor entries for the same name. [GL #1237]
-
-Bug Fixes
-
- * Fixed an intermittent crash in the validator that could occur when
- validating negative answers from the cache. [GL #1561]
-
- * Fixed a bug that could cause named to crash on machines with more than
- 40 CPUs. [GL #1493]
-
- * Socket-related statistics counters were not being updated by network
- manager sockets, but are now fully functional. [GL #1311]
-
-Notes for BIND 9.15.7
-
-Feature Changes
-
- * The dnssec-keys configuration statement, which was introduced in
- 9.15.1 and revised in 9.15.6, has now been renamed to the more
- descriptive trust-anchors. [GL !2702]
-
- (See release notes for BIND 9.15.1 and BIND 9.15.6 for prior
- discussion of this feature.)
-
- * Added support for multithreaded listening for TCP connections in the
- network manager. [GL !2659]
-
-Bug Fixes
-
- * Fixed a bug that caused named to leak memory on reconfiguration when
- any GeoIP2 database was in use. [GL #1445]
-
- * Fixed several possible race conditions discovered by ThreadSanitizer.
-
-Notes for BIND 9.15.6
-
-Security Fixes
-
- * Set a limit on the number of concurrently served pipelined TCP
- queries. This flaw is disclosed in CVE-2019-6477. [GL #1264]
-
-New Features
-
- * A new asynchronous network communications system based on libuv is now
- used by named for listening for incoming requests and responding to
- them. This change will make it easier to improve performance and
- implement new protocol layers (for example, DNS over TLS) in the
- future. [GL #29]
-
- * The new dnssec-policy option allows the configuration key and signing
- policy (KASP) for zones. This option enables named to generate new
- keys as needed and automatically roll both ZSK and KSK keys. (Note
- that the syntax for this statement differs from the DNSSEC policy used
- by dnssec-keymgr.) [GL #1134]
-
- * Two new keywords have been added to the dnssec-keys statement:
- initial-ds and static-ds. These allow the use of trust anchors in DS
- format instead of DNSKEY format. DS format allows trust anchors to be
- configured for keys that have not yet been published; this is the
- format used by IANA when announcing future root keys.
-
- As with the initial-key and static-key keywords, initial-ds configures
- a dynamic trust anchor to be maintained via RFC 5011, and static-ds
- configures a permanent trust anchor.
-
- (Note: Currently, DNSKEY-format and DS-format trust anchors cannot
- both be used for the same domain name.) [GL #6] [GL #622]
-
- * Added a new statistics variable tcp-highwater that reports the maximum
- number of simultaneous TCP clients BIND has handled while running. [GL
- #1206]
-
-Feature Changes
-
- * NSEC Aggressive Cache (synth-from-dnssec) has been disabled by default
- because it was found to have a significant performance impact on the
- recursive service. The NSEC Aggressive Cache will be enable by default
- in the future releases. [GL #1265]
-
- * The DNSSEC validation code has been refactored for clarity and to
- reduce code duplication. [GL #622]
-
-Notes for BIND 9.15.5
-
-Security Fixes
-
- * named could crash with an assertion failure if a forwarder returned a
- referral, rather than resolving the query, when QNAME minimization was
- enabled. This flaw is disclosed in CVE-2019-6476. [GL #1051]
-
- * A flaw in DNSSEC verification when transferring mirror zones could
- allow data to be incorrectly marked valid. This flaw is disclosed in
- CVE-2019-6475. [GL #1252]
-
-Notes for BIND 9.15.4
-
-New Features
-
- * Added a new command line option to dig: +[no]unexpected. By default,
- dig won't accept a reply from a source other than the one to which it
- sent the query. Add the +unexpected argument to enable it to process
- replies from unexpected sources.
-
- * dig, mdig and delv can all now take a +yaml option to print output in
- a a detailed YAML format. [RT #1145]
-
-Bug Fixes
-
- * When a response-policy zone expires, ensure that its policies are
- removed from the RPZ summary database. [GL #1146]
-
-Notes for BIND 9.15.3
-
-New Features
-
- * Statistics channel groups are now toggleable. [GL #1030]
-
-Removed Features
-
- * DNSSEC Lookaside Validation (DLV) is now obsolete. The
- dnssec-lookaside option has been marked as deprecated; when used in
- named.conf, it will generate a warning but will otherwise be ignored.
- All code enabling the use of lookaside validation has been removed
- from the validator, delv, and the DNSSEC tools. [GL #7]
-
-Feature Changes
-
- * A SipHash 2-4 based DNS Cookie (RFC 7873) algorithm has been added and
- made default. Old non-default HMAC-SHA based DNS Cookie algorithms
- have been removed, and only the default AES algorithm is being kept
- for legacy reasons. This change doesn't have any operational impact in
- most common scenarios. [GL #605]
-
- If you are running multiple DNS Servers (different versions of BIND 9
- or DNS server from multiple vendors) responding from the same IP
- address (anycast or load-balancing scenarios), you'll have to make
- sure that all the servers are configured with the same DNS Cookie
- algorithm and same Server Secret for the best performance.
-
- * The information from the dnssec-signzone and dnssec-verify commands is
- now printed to standard output. The standard error output is only used
- to print warnings and errors, and in case the user requests the signed
- zone to be printed to standard output with -f - option. A new
- configuration option -q has been added to silence all output on
- standard output except for the name of the signed zone.
-
- * DS records included in DNS referral messages can now be validated and
- cached immediately, reducing the number of queries needed for a DNSSEC
- validation. [GL #964]
-
-Bug Fixes
-
- * Cache database statistics counters could report invalid values when
- stale answers were enabled, because of a bug in counter maintenance
- when cache data becomes stale. The statistics counters have been
- corrected to report the number of RRsets for each RR type that are
- active, stale but still potentially served, or stale and marked for
- deletion. [GL #602]
-
- * Interaction between DNS64 and RPZ No Data rule (CNAME *.) could cause
- unexpected results; this has been fixed. [GL #1106]
-
- * named-checkconf now checks DNS64 prefixes to ensure bits 64-71 are
- zero. [GL #1159]
-
- * named-checkconf now correctly reports a missing dnstap-output option
- when dnstap is set. [GL #1136]
-
- * Handle ETIMEDOUT error on connect() with a non-blocking socket. [GL #
- 1133]
-
- * dig now correctly expands the IPv6 address when run with +expandaaaa
- +short. [GL #1152]
-
-Notes for BIND 9.15.2
-
-New Features
-
- * The GeoIP2 API from MaxMind is now supported. Geolocation support will
- be compiled in by default if the libmaxminddb library is found at
- compile time, but can be turned off by using configure --disable-geoip
- .
-
- The default path to the GeoIP2 databases will be set based on the
- location of the libmaxminddb library; for example, if it is in /usr/
- local/lib, then the default path will be /usr/local/share/GeoIP. This
- value can be overridden in named.conf using the geoip-directory
- option.
-
- Some geoip ACL settings that were available with legacy GeoIP,
- including searches for netspeed, org, and three-letter ISO country
- codes, will no longer work when using GeoIP2. Supported GeoIP2
- database types are country, city, domain, isp, and as. All of these
- databases support both IPv4 and IPv6 lookups. [GL #182] [GL #1112]
-
- * Two new metrics have been added to the statistics-channel to report
- DNSSEC signing operations. For each key in each zone, the dnssec-sign
- counter indicates the total number of signatures named has generated
- using that key since server startup, and the dnssec-refresh counter
- indicates how many of those signatures were refreshed during zone
- maintenance, as opposed to having been generated as a result of a zone
- update. [GL #513]
-
-Bug Fixes
-
- * When qname-minimization was set to relaxed, some improperly configured
- domains would fail to resolve, but would have succeeded when
- minimization was disabled. named will now fall back to normal
- resolution in such cases, and also uses type A rather than NS for
- minimal queries in order to reduce the likelihood of encountering the
- problem. [GL #1055]
-
- * ./configure no longer sets --sysconfdir to /etc or --localstatedir to
- /var when --prefix is not specified and the aforementioned options are
- not specified explicitly. Instead, Autoconf's defaults of $prefix/etc
- and $prefix/var are respected.
-
- * Glue address records were not being returned in responses to root
- priming queries; this has been corrected. [GL #1092]
-
-Notes for BIND 9.15.1
-
-Security Fixes
-
- * A race condition could trigger an assertion failure when a large
- number of incoming packets were being rejected. This flaw is disclosed
- in CVE-2019-6471. [GL #942]
-
-New Features
-
- * In order to clarify the configuration of DNSSEC keys, the trusted-keys
- and managed-keys statements have been deprecated, and the new
- dnssec-keys statement should now be used for both types of key.
-
- When used with the keyword initial-key, dnssec-keys has the same
- behavior as managed-keys, i.e., it configures a trust anchor that is
- to be maintained via RFC 5011.
-
- When used with the new keyword static-key, it has the same behavior as
- trusted-keys, configuring a permanent trust anchor that will not
- automatically be updated. (This usage is not recommended for the root
- key.) [GL #6]
-
-Removed Features
-
- * The cleaning-interval option has been removed. [GL !1731]
-
-Feature Changes
-
- * named will now log a warning if a static key is configured for the
- root zone. [GL #6]
-
- * JSON-C is now the only supported library for enabling JSON support for
- BIND statistics. The configure option has been renamed from
- --with-libjson to --with-json-c. Use PKG_CONFIG_PATH to specify a
- custom path to the json-c library as the new configure option does not
- take the library installation path as an optional argument.
-
-Notes for BIND 9.15.0
-
-Security Fixes
-
- * In certain configurations, named could crash with an assertion failure
- if nxdomain-redirect was in use and a redirected query resulted in an
- NXDOMAIN from the cache. This flaw is disclosed in CVE-2019-6467. [GL
- #880]
-
- * The TCP client quota set using the tcp-clients option could be
- exceeded in some cases. This could lead to exhaustion of file
- descriptors. This flaw is disclosed in CVE-2018-5743. [GL #615]
-
-New Features
-
- * The new add-soa option specifies whether or not the response-policy
- zone's SOA record should be included in the additional section of RPZ
- responses. [GL #865]
-
-Removed Features
-
- * The dnssec-enable option has been obsoleted and no longer has any
- effect. DNSSEC responses are always enabled if signatures and other
- DNSSEC data are present. [GL #866]
-
-Feature Changes
-
- * When static and managed DNSSEC keys were both configured for the same
- name, or when a static key was used to configure a trust anchor for
- the root zone and dnssec-validation was set to the default value of
- auto, automatic RFC 5011 key rollovers would be disabled. This
- combination of settings was never intended to work, but there was no
- check for it in the parser. This has been corrected, and it is now a
- fatal configuration error. [GL #868]
-
- * DS and CDS records are now generated with SHA-256 digests only,
- instead of both SHA-1 and SHA-256. This affects the default output of
- dnssec-dsfromkey, the dsset files generated by dnssec-signzone, the DS
- records added to a zone by dnssec-signzone based on keyset files, the
- CDS records added to a zone by named and dnssec-signzone based on
- "sync" timing parameters in key files, and the checks performed by
- dnssec-checkds.
-
-Bug Fixes
-
- * The allow-update and allow-update-forwarding options were
- inadvertently treated as configuration errors when used at the options
- or view level. This has now been corrected. [GL #913]
