60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Added support for DynDB, a new interface for loading zone data
b397f922936e9f73aa8c3ea40be3ad74285dacaaTinderbox User from an external database, developed by Red Hat for the FreeIPA
b397f922936e9f73aa8c3ea40be3ad74285dacaaTinderbox User project. (Thanks in particular to Adam Tkac and Petr
b397f922936e9f73aa8c3ea40be3ad74285dacaaTinderbox User Spacek of Red Hat for the contribution.)
507151045be68c671ffd4e2f37e17cdfa0376fc4Automatic Updater Unlike the existing DLZ and SDB interfaces, which provide a
507151045be68c671ffd4e2f37e17cdfa0376fc4Automatic Updater limited subset of database functionality within BIND —
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein translating DNS queries into real-time database lookups with
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein relatively poor performance and with no ability to handle
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein DNSSEC-signed data — DynDB is able to fully implement
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews and extend the database API used natively by BIND.
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews A DynDB module could pre-load data from an external data
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews source, then serve it with the same performance and
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein functionality as conventional BIND zones, and with the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein ability to take advantage of database features not
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews available in BIND, such as multi-master replication.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein New quotas have been added to limit the queries that are
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein sent by recursive resolvers to authoritative servers
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein experiencing denial-of-service attacks. When configured,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein these options can both reduce the harm done to authoritative
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein servers and also avoid the resource exhaustion that can be
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein experienced by recursives when they are being used as a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein vehicle for such an attack.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; ">
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <code class="option">fetches-per-server</code> limits the number of
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein simultaneous queries that can be sent to any single
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein authoritative server. The configured value is a starting
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein point; it is automatically adjusted downward if the server is
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein partially or completely non-responsive. The algorithm used to
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein adjust the quota can be configured via the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <code class="option">fetch-quota-params</code> option.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <code class="option">fetches-per-zone</code> limits the number of
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein simultaneous queries that can be sent for names within a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein single domain. (Note: Unlike "fetches-per-server", this
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein value is not self-tuning.)
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Statistics counters have also been added to track the number
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein of queries affected by these quotas.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Added support for <span class="command"><strong>dnstap</strong></span>, a fast,

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein libraries must be available, and BIND must be configured with
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein A new utility <span class="command"><strong>dnstap-read</strong></span> has been added
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein to allow <span class="command"><strong>dnstap</strong></span> data to be presented in
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews a human-readable format.

b05bdb520d83f7ecaad708fe305268c3420be01dMark Andrews New statistics counters have been added to track traffic
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews sizes, as specified in RSSAC002. Query and response
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews message sizes are broken up into ranges of histogram buckets:
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews TCP and UDP queries of size 0-15, 16-31, ..., 272-288, and 288+,
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews and TCP and UDP responses of size 0-15, 16-31, ..., 4080-4095,
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews and 4096+. These values can be accessed via the XML and JSON

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein A new DNSSEC key management utility,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span class="command"><strong>dnssec-keymgr</strong></span>, has been added. This tool
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein is meant to run unattended (e.g., under <span class="command"><strong>cron</strong></span>).
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein It reads a policy definition file
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein (default: <code class="filename">/etc/dnssec.policy</code>)
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein and creates or updates DNSSEC keys as necessary to ensure that a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein zone's keys match the defined policy for that zone. New keys are
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein created whenever necessary to ensure rollovers occur correctly.
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater Existing keys' timing metadata is adjusted as needed to set the
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater correct rollover period, prepublication interval, etc. If
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater the configured policy changes, keys are corrected automatically.
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater See the <span class="command"><strong>dnssec-keymgr</strong></span> man page for full details.
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater Note: <span class="command"><strong>dnssec-keymgr</strong></span> depends on Python and on
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater the Python lex/yacc module, PLY. The other Python-based tools,
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater <span class="command"><strong>dnssec-coverage</strong></span> and
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater <span class="command"><strong>dnssec-checkds</strong></span>, have been
afb33f777af856f8c3382604a7a8ffdfe2b512c5Automatic Updater refactored and updated as part of this work.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein 95 Hackathon in Buenos Aires, April 2016.)
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The serial number of a dynamically updatable zone can
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein now be set using
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span class="command"><strong>rndc signing -serial <em class="replaceable"><code>number</code></em> <em class="replaceable"><code>zonename</code></em></strong></span>.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein This is particularly useful with <code class="option">inline-signing</code>
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein zones that have been reset. Setting the serial number to a value
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein larger than that on the slaves will trigger an AXFR-style
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein When answering recursive queries, SERVFAIL responses can now be
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein cached by the server for a limited time; subsequent queries for

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein now reported with millisecond accuracy. [RT #40082]
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Updated the compiled-in addresses for H.ROOT-SERVERS.NET
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein ACLs containing <span class="command"><strong>geoip asnum</strong></span> elements were
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein not correctly matched unless the full organization name was
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein specified in the ACL (as in
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span class="command"><strong>geoip asnum "AS1234 Example, Inc.";</strong></span>).
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein They can now match against the AS number alone (as in
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span class="command"><strong>geoip asnum "AS1234";</strong></span>).
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein When using native PKCS#11 cryptography (i.e.,
9941177e7eb530451d5970959cc2828c53cb36c9Tinderbox User <span class="command"><strong>configure --enable-native-pkcs11</strong></span>) HSM PINs
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein of up to 256 characters can now be used.
f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce NXDOMAIN responses to queries of type DS are now cached separately
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein from those for other types. This helps when using "grafted" zones
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein of type forward, for which the parent zone does not contain a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein delegation, such as local top-level domains. Previously a query
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein of type DS for such a zone could cause the zone apex to be cached
9941177e7eb530451d5970959cc2828c53cb36c9Tinderbox User as NXDOMAIN, blocking all subsequent queries. (Note: This
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein change is only helpful when DNSSEC validation is not enabled.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein "Grafted" zones without a delegation in the parent are not a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein recommended configuration.)
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews Update forwarding performance has been improved by allowing
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein a single TCP connection to be shared between multiple updates.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein By default, <span class="command"><strong>nsupdate</strong></span> will now check
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the correctness of hostnames when adding records of type
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein A, AAAA, MX, SOA, NS, SRV or PTR. This behavior can be
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein disabled with <span class="command"><strong>check-names no</strong></span>.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Added support for OPENPGPKEY type.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The names of the files used to store managed keys and added
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein zones for each view are no longer based on the SHA256 hash
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein of the view name, except when this is necessary because the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein view name contains characters that would be incompatible with use
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews as a file name. For views whose names do not contain forward
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews slashes ('/'), backslashes ('\'), or capital letters - which
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein could potentially cause namespace collision problems on
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein case-insensitive filesystems - files will now be named
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein after the view (for example, <code class="filename">internal.mkeys</code>
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein or <code class="filename">external.nzf</code>). However, to ensure
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein consistent behavior when upgrading, if a file using the old
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews name format is found to exist, it will continue to be used.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein "rndc" can now return text output of arbitrary size to
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the caller. (Prior to this, certain commands such as
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews "rndc tsig-list" and "rndc zonestatus" could return
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews truncated output.)
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews Errors reported when running <span class="command"><strong>rndc addzone</strong></span>
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews (e.g., when a zone file cannot be loaded) have been clarified
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein to make it easier to diagnose problems.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein When encountering an authoritative name server whose name is
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein an alias pointing to another name, the resolver treats
035992291cb70ec3be4046fcea921b4a6acb1c77Mark Andrews this as an error and skips to the next server. Previously
035992291cb70ec3be4046fcea921b4a6acb1c77Mark Andrews this happened silently; now the error will be logged to
035992291cb70ec3be4046fcea921b4a6acb1c77Mark Andrews the newly-created "cname" log category.
68b30890ebd441a6a1ae3fdf71744d07d02cd030Mark Andrews If <span class="command"><strong>named</strong></span> is not configured to validate
035992291cb70ec3be4046fcea921b4a6acb1c77Mark Andrews answers, then allow fallback to plain DNS on timeout even when
68b30890ebd441a6a1ae3fdf71744d07d02cd030Mark Andrews we know the server supports EDNS. This will allow the server to
035992291cb70ec3be4046fcea921b4a6acb1c77Mark Andrews potentially resolve signed queries when TCP is being
035992291cb70ec3be4046fcea921b4a6acb1c77Mark Andrews Large inline-signing changes should be less disruptive.
035992291cb70ec3be4046fcea921b4a6acb1c77Mark Andrews Signature generation is now done incrementally; the number
9c6a5d1f22f972232d7a9fd5c5fa64f10bacbdffAutomatic Updater of signatures to be generated in each quantum is controlled
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews by "sig-signing-signatures <em class="replaceable"><code>number</code></em>;".
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews The experimental SIT option (code point 65001) of BIND
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews 9.10.0 through BIND 9.10.2 has been replaced with the COOKIE
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews option (code point 10). It is no longer experimental, and
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews is sent by default, by both <span class="command"><strong>named</strong></span> and
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews <span class="command"><strong>dig</strong></span>.
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews The SIT-related named.conf options have been marked as
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews obsolete, and are otherwise ignored.
4556ad3a270bf049b3225433a402666aaffe3c36Mark Andrews When <span class="command"><strong>dig</strong></span> receives a truncated (TC=1)
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein response or a BADCOOKIE response code from a server, it
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein will automatically retry the query using the server COOKIE
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein that was returned by the server in its initial response.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein A alternative NXDOMAIN redirect method (nxdomain-redirect)
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews which allows the redirect information to be looked up from
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein a namespace on the Internet rather than requiring a zone
bea931e17b7567f09107f93ab7e25c7f00abeb9cMark Andrews to be configured on the server is now available.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Retrieving the local port range from net.ipv4.ip_local_port_range
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein on Linux is now supported.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Within the <code class="option">response-policy</code> option, it is now
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein possible to configure RPZ rewrite logging on a per-zone basis
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews using the <code class="option">log</code> clause.
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews The default preferred glue is now the address type of the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein transport the query was received over.
ac93437301f55ed69bf85883a497a75598c628f9Automatic Updater On machines with 2 or more processors (CPU), the default value
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein for the number of UDP listeners has been changed to the number
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein of detected processors minus one.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Zone transfers now use smaller message sizes to improve
9941177e7eb530451d5970959cc2828c53cb36c9Tinderbox User message compression. This results in reduced network usage.
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews Added support for the AVC resource record type (Application
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Visibility and Control).
