Security Fixes

   Treat an all zero netmask as invalid when generating the localnets
   acl to workaround bug on Windows platform. [CVE-2013-6230] [RT #34687]

   Fix crashes when serving some NSEC3 signed zones. memcpy was
   incorrectly called with overlapping ranges, resulting in malformed
   names being generated on some platforms. This could cause INSIST
   failures. (CVE 2014-0591) [RT #35120]

Features Changes

   Add the ability to specify ndots to "nslookup". [RT #34711]

   Introduce a new tool "dnssec-importkey" to allow externally-generated
   DNSKEY to be imported into the DNSKEY management framework. [RT #34698]

   Check that EDNS subnet client options are well formed. [RT #34718]

   "named" now preserves the capitalization of names when responding
   to queries. [RT #34737]

   Include a comment in .nzf files (used for adding new zones via
   "rndc"), giving the name of the associated view. [RT #34765]

   Use separate rate limiting queues for refresh and notify requests.
   [RT #30589]

   Adjust when a master server is deemed unreachable to be less
   aggressive. [RT #27075]

   Create delegations for all "children" of empty zones except
   "forward first". [RT #34826]

   Changed the name of "" developers script (for
   outputting compiler and linker flags) to "bind9-config". [RT #23825]

   Add "dig" option to keep the TCP socket open between successive
   queries (+[no]keepopen).  [RT #34918]

   Add dns_client_createx2() function to DNS Client API to provide
   a way to specify the local address for use when sending update
   packets. [RT #34811]

   "named-checkconf -z" now checks zones of type hint as well as
   master. [RT #35046]

   Update config.guess and config.sub to add support for ppc64le
   (powerpc 64-bit Little Endian). [RT #35060]

   Update the Windows build system to support feature selection and
   WIN64 builds. This is a work in progress. [RT #34160]

   Add "dnssec-signzone -Q" switch to drop signatures from keys
   that are still published but no longer active.  [RT #34990]

   Add a more detailed "not found" message to "rndc" commands which
   specify a zone name. [RT #35059]

   named will now warn when a zone's configured "key-directory"
   does not exist or is not a directory. [RT #35108]

   Added improvements to statistics channel XSL stylesheet: the
   stylesheet can now be cached by the browser; section headers are
   omitted from the stats display when there is no data in those
   sections to be displayed; counters are now right-justified for
   easier readability. (Only available with ./configure --enable-newstats.)
   [RT #35117]

   "named-checkconf" can now obscure shared secrets when printing
   by specifying '-x'. [RT #34465]

   "named" can now accept integer timestamps in RRSIG records. [RT #35185]

   The export-library API call for loading "resolv.conf",
   irs_resconf_load(), has been modified to return ISC_R_FILENOTFOUND
   when the file does not exist and initializes the resconf structure
   as if the file had existed and configured with nameservers at
   the localhost addresses ( and ::1). [RT #35194]

Bug Fixes

   Treat type 65533 (KEYDATA) as opaque except when used in a key
   zone. [RT #34238]

   Fix "host" and "nslookup" so don't need dot after the domain by
   checking ndots when searching. Only continue searching on NXDOMAIN
   responses. [RT #34711]

   Handle changes to sig-validity-interval settings better. [RT #34625]

   Fix bug where journal filename string could be set incorrectly,
   causing garbage in log messages. [RT #34738]

   dependencies/rules for python programs as make won't use the

   order reversal deadlock with inline zones. [RT #34856]

   Fix "host" failure if a UDP query timed out. [RT #34870]

   Fix a potential hang with failure to release lock on error in
   receive_secure_db. #34944]

   issue with potential bad data in a database used by DLZ or SDB.
   [RT #34993]

   build. [RT #35001]

   Fixed a bug causing an insecure delegation from one "static-stub"
   zone to another to fail with a broken trust chain. [RT #35081]

   Fixed problem where iterative responses could be discarded when
   the "query-source" port for an upstream query was the same as
   the listener port (53). [RT #34925]

   Fix crashes in RBTDB implementation. Two calls to dns_db_getoriginnode
   were fatal if there was no data at the node. [RT #35080]

   Fix a possible race and crash in the socket_search() function
   in dispatch.c. [RT #35107]
