Security Fixes

     * On servers configured to perform DNSSEC validation using managed
       trust anchors (i.e., keys configured explicitly via managed-keys,
       or implicitly via dnssec-validation auto; or dnssec-lookaside
       auto;), revoking a trust anchor and sending a new untrusted
       replacement could cause named to crash with an assertion failure.
       This could occur in the event of a botched key rollover, or
       potentially as a result of a deliberate attack if the attacker was
       in position to monitor the victim's DNS traffic.
       This flaw was discovered by Jan-Piet Mens, and is disclosed in
       CVE-2015-1349. [RT #38344]
     * A flaw in delegation handling could be exploited to put named into
       an infinite loop, in which each lookup of a name server triggered
       additional lookups of more name servers. This has been addressed by
       placing limits on the number of levels of recursion named will
       allow (default 7), and on the number of queries that it will send
       before terminating a recursive query (default 50).
       The recursion depth limit is configured via the max-recursion-depth
       option, and the query limit via the max-recursion-queries option.
       The flaw was discovered by Florian Maury of ANSSI, and is disclosed
       in CVE-2014-8500. [RT #37580]

New Features

     * None

Feature Changes

     * NXDOMAIN responses to queries of type DS are now cached separately
       from those for other types. This helps when using "grafted" zones
       of type forward, for which the parent zone does not contain a
       delegation, such as local top-level domains. Previously a query of
       type DS for such a zone could cause the zone apex to be cached as
       NXDOMAIN, blocking all subsequent queries. (Note: This change is
       only helpful when DNSSEC validation is not enabled. "Grafted" zones
       without a delegation in the parent are not a recommended
     * NOTIFY messages that are sent because a zone has been updated are
       now given priority above NOTIFY messages that were scheduled when
       the server started up. This should mitigate delays in zone
       propagation when servers are restarted frequently.
     * Errors reported when running rndc addzone (e.g., when a zone file
       cannot be loaded) have been clarified to make it easier to diagnose
     * Added support for OPENPGPKEY type.
     * When encountering an authoritative name server whose name is an
       alias pointing to another name, the resolver treats this as an
       error and skips to the next server. Previously this happened
       silently; now the error will be logged to the newly-created "cname"
       log category.
     * If named is not configured to validate the answer then allow
       fallback to plain DNS on timeout even when we know the server
       supports EDNS. This will allow the server to potentially resolve
       signed queries when TCP is being blocked.

Bug Fixes

     * dig, host and nslookup aborted when encountering a name which,
       after appending search list elements, exceeded 255 bytes. Such
       names are now skipped, but processing of other names will continue.
       [RT #36892]
     * The error message generated when named-checkzone or named-checkconf
       -z encounters a $TTL directive without a value has been clarified.
       [RT #37138]
     * Semicolon characters (;) included in TXT records were incorrectly
       escaped with a backslash when the record was displayed as text.
       This is actually only necessary when there are no quotation marks.
       [RT #37159]
     * When files opened for writing by named, such as zone journal files,
       were referenced more than once in named.conf, it could lead to file
       corruption as multiple threads wrote to the same file. This is now
       detected when loading named.conf and reported as an error. [RT
     * dnssec-keygen -S failed to generate successor keys for some
       algorithm types (including ECDSA and GOST) due to a difference in
       the content of private key files. This has been corrected. [RT
     * UPDATE messages that arrived too soon after an rndc thaw could be
       lost. [RT #37233]
     * Forwarding of UPDATE messages did not work when they were signed
       with SIG(0); they resulted in a BADSIG response code. [RT #37216]
     * When checking for updates to trust anchors listed in managed-keys,
       named now revalidates keys based on the current set of active trust
       anchors, without relying on any cached record of previous
       validation. [RT #37506]
     * When NXDOMAIN redirection is in use, queries for a name that is
       present in the redirection zone but a type that is not present will
       now return NOERROR instead of NXDOMAIN.
     * When a zone contained a delegation to an IPv6 name server but not
       an IPv4 name server, it was possible for a memory reference to be
       left un-freed. This caused an assertion failure on server shutdown,
       but was otherwise harmless. [RT #37796]
     * Due to an inadvertent removal of code in the previous release, when
       named encountered an authoritative name server which dropped all
       EDNS queries, it did not always try plain DNS. This has been
       corrected. [RT #37965]
     * A regression caused nsupdate to use the default recursive servers
       rather than the SOA MNAME server when sending the UPDATE.
     * Adjusted max-recursion-queries to better accommodate empty caches.
     * Built-in "empty" zones did not correctly inherit the
       "allow-transfer" ACL from the options or view. [RT #38310]
     * A mutex leak was fixed that could cause named processes to grow to
       very large sizes. [RT #38454]
     * Fixed some bugs in RFC 5011 trust anchor management, including a
       memory leak and a possible loss of state information.[RT #38458]

New Features

   Support for CAA record types, as described in RFC 6844 "DNS
   Certification Authority Authorization (CAA) Resource Record",
   was added. [RT#36625] [RT #36737]

   Disallow "request-ixfr" from being specified in zone statements
   where it is not valid (it is only valid for slave and redirect
   zones) [RT #36608]

   Support for CDS and CDNSKEY resource record types was added. For
   details see the proposed Informational Internet-Draft "Automating
   DNSSEC Delegation Trust Maintenance" at
   http://tools.ietf.org/html/draft-ietf-d … inance-14.
   [RT #36333]

   Added version printing options to various BIND utilities. [RT #26057]
   [RT #10686]

   On Windows, enable the Python tools "dnssec-coverage" and
   "dnssec-checkds". [RT #34355]

   Added a "no-case-compress" ACL, which causes named to use
   case-insensitive compression (disabling change #3645) for specified
   clients. (This is useful when dealing with broken client
   implementations that use case-sensitive name comparisons, rejecting
   responses that fail to match the capitalization of the query
   that was sent.) [RT #35300]

Feature Changes

   Adds RPZ SOA to the additional section of responses to clearly
   indicate the use of RPZ in a manner that is intended to avoid
   causing issues for downstream resolvers and forwarders [RT #36507]

   rndc now gives distinct error messages when an unqualified zone
   name matches multiple views vs. matching no views [RT #36691]

   Improves the accuracy of dig's reported round trip times.  [RT #36611]

   The Windows installer now places files in the Program Files area
   rather than system services. [RT #35361]

   When an SPF record exists in a zone but no equivalent TXT record
   does, a warning will be issued.  The warning for the reverse
   condition is no longer issued. See the check-spf option in the
   documentation for details. [RT #36210]

   "named" will now log explicitly when using rndc.key to configure
   command channel. [RT #35316]

   The default setting for the -U option (setting the number of UDP
   listeners per interface) has been adjusted to improve performance.
   [RT #35417]

   Aging of smoothed round-trip time measurements is now limited
   to no more than once per second, to improve accuracy in selecting
   the best name server. [RT #32909]

   DNSSEC keys that have been marked active but have no publication
   date are no longer presumed to be publishable. [RT #35063]

Bug Fixes

   The Makefile in bin/python was changed to work around a bmake
   bug in FreeBSD 10 and NetBSD 6. [RT #36993] (**)

   Corrected bugs in the handling of wildcard records by the DNSSEC
   validator: invalid wildcard expansions could be treated as valid
   if signed, and valid wildcard expansions in NSEC3 opt-out ranges
   had the AD bit set incorrectly in responses. [RT #37093] [RT #37072]

   When resigning, dnssec-signzone was removing all signatures from
   delegation nodes. It now retains DS and (if applicable) NSEC
   signatures.  [RT #36946]

   The AD flag was being set inappopriately on RPZ responses. [RT #36833]

   Updates the URI record type to current draft standard,
   draft-faltstrom-uri-08, and allows the value field to be zero
   length [RT #36642] [RT #36737]

   RRSIG sets that were not loaded in a single transaction at start
   up were not being correctly added to re-signing heaps.  [RT #36302]

   Setting '-t aaaa' in .digrc had unintended side-effects. [RT #36452]

   A race condition could cause a crash in isc_event_free during
   shutdown.  [RT #36720]

   Addresses a race condition issue in dispatch. [RT #36731]

   acl elements could be miscounted, causing a crash while loading
   a config [RT #36675]

   Corrects a deadlock between view.c and adb.c. [RT #36341]

   liblwres wasn't properly handling link-local addresses in
   nameserver clauses in resolv.conf. [RT #36039]

   Buffers in isc_print_vsnprintf were not properly initialized
   leading to potential overflows when printing out quad values.
   [RT #36505]

   Don't call qsort() with a null pointer, and disable the GCC 4.9
   "delete null pointer check" optimizer option. This fixes problems
   when using GNU GCC 4.9.0 where its compiler code optimizations
   may cause crashes in BIND. For more information, see the operational
   advisory at https://kb.isc.org/article/AA-01167/. [RT #35968]

   Fixed a bug that could cause repeated resigning of records in
   dynamically signed zones. [RT #35273]

   Fixed a bug that could cause an assertion failure after forwarding
   was disabled. [RT #35979]

   Fixed a bug that caused SERVFAILs when using RPZ on a system
   configured as a forwarder. [RT #36060]

   Worked around a limitation in Solaris's /dev/poll implementation
   that could cause named to fail to start when configured to use
   more sockets than the system could accomodate. [RT #35878]
