- Prevents a named assert (crash) when queried for a record whose RDATA exceeds 65535 bytes. [RT #30416]
- Prevents a named assert (crash) when validating caused by using "Bad cache" data before it has been initialized. [RT #30025]
condition has been corrected where improper handling of zero-length
RDATA could cause undesirable behavior, including termination of the
named process. [RT #29644]
- BIND now recognizes the TLSA resource record type, created to support IETF DANE (DNS-based Authentication of Named Entities) [RT #28989]
- 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 tests on random jitter values that are used when handling zone
refreshes have been relaxed. Prior to this change named could terminate
unexpectedly when processing stub zones. [RT# 19821]
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]
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]
- 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]
- Uses hmctx, not mctx when freeing rbtdb->heaps to avoid triggering an assertion when flushing cache data. [RT #28571]
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]
