Security Fixes
- Prevents a named assert (crash) when validating caused by using
"Bad cache" data before it has been initialized. [RT #30025]
- A condition has been corrected where improper handling of zero-length
RDATA could cause undesirable behavior, including termination of
the named process. [RT #29644]
New Features
- None
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
- Fixes the defect introduced by change #3314 that was causing
failures when saving stub zones to disk (resulting in excessive
CPU usage in some cases). [RT #29952]
- 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]
