Introduction

   BIND 9.6-ESV-R11rc1 is the first release candidate for BIND
   9.6-ESV-R11.

   BIND 9.6-ESV is an Extended Support Version of BIND. The BIND
   9.6-ESV branch will reach its End of Life in January 2014.  There
   will be no further bug fixes to it of any kind and BIND 9.6-ESV-R11
   will be our final release version of the 9.6 releases. We recommend
   that you plan your upgrade to BIND 9.9.4 or higher.  BIND 9.9
   is our current ESV Extended Support Version and will be supported
   for three more years.

   This document summarizes changes from BIND 9.6-ESV-R10 to BIND

Security Fixes

   Treat an all zero netmask as invalid when generating the localnets
   acl to work around a bug on the 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] **

Feature Changes

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

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

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

   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 "isc-config.sh" 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]

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

   (powerpc 64-bit Little Endian). [RT #35060]

Bug Fixes

   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]

   Address race condition with manual notify requests. [RT #34806]

   Address bugs in dns_rdata_fromstruct and dns_rdata_tostruct for
   WKS and ISDN types. [RT #34910]
