Security Fixes

  • Windows binary packages distributed by ISC are now built and linked against OpenSSL 1.0.0i

New Features


Feature Changes
  • BIND now recognizes the TLSA resource record type, created to support IETF DANE (DNS-based Authentication of Named Entities) [RT #28989]
Bug Fixes
  • The locking strategy around the handling of iterative queries has been tuned to reduce unnecessary contention in a multi-threaded environment.  (Note that this may not provide a measurable improvement over previous versions of BIND, but it corrects the performance impact of change 3309 / RT #27995) [RT #29239] 
  • Addresses a race condition that can cause named to to crash when the masters list for a zone is updated via rndc reload/reconfig [RT #26732]
  • named-checkconf now correctly validates dns64 clients acl definitions. [RT #27631] 
  • Fixes a race condition in zone.c that can cause named to crash during the processing of rndc delzone [RT #29028]
  • Prevents a named segfault from resolver.c due to procedure fctx_finddone() not being thread-safe.  [RT #27995] 
  • Improves DNS64 reverse zone performance. [RT #28563]
  • Adds wire format lookup method to sdb. [RT #28563] 
  • Uses hmctx, not mctx when freeing rbtdb->heaps to avoid triggering an assertion when flushing cache data. [RT #28571] 
  • Resolves inconsistencies in locating DNSSEC keys where zone names contain characters that require special mappings [RT #28600]
  • A new flag -R  has been added to queryperf for running tests using non-recursive queries.  It also now builds correctly on MacOS version 10.7 (darwin)  [RT #28565] 
  • Named no longer crashes if gssapi is enabled in named.conf but was not compiled into the binary [RT #28338]
  • SDB now handles unexpected errors from back-end database drivers gracefully instead of exiting on an assert. [RT #28534]
