- Adding a NO DATA signed negative response to cache failed to clear
- any matching RRSIG records already in cache. A subsequent lookup
- of the cached NO DATA entry could crash named (INSIST) when the
- unexpected RRSIG was also returned with the NO DATA cache entry.

- BIND, acting as a DNSSEC validator, was determining if the NS RRset
- is insecure based on a value that could mean either that the RRset
- is actually insecure or that there wasn't a matching key for the RRSIG
- in the DNSKEY RRset when resuming from validating the DNSKEY RRset.
- This can happen when in the middle of a DNSKEY algorithm rollover,
- when two different algorithms were used to sign a zone but only the
- new set of keys are in the zone DNSKEY RRset.

- BIND now builds with threads disabled in versions of NetBSD earlier
- than 5.0 and with pthreads enabled by default in NetBSD versions 5.0
- and higher. Also removes support for unproven-pthreads, mit-pthreads
- and ptl2. [RT #19203]
- </li><li class="listitem">
- HPUX now correctly defaults to using /dev/poll, which should
- increase performance. [RT #21919]
- </li><li class="listitem">
- If named is running as a threaded application, after an "rndc stop"
- command has been issued, other inbound TCP requests can cause named
- to hang and never complete shutdown. [RT #22108]
- </li><li class="listitem">
- When performing a GSS-TSIG signed dynamic zone update, memory could be
- leaked. This causes an unclean shutdown and may affect long-running
- servers. [RT #22573]
- </li><li class="listitem">
- A bug in NetBSD and FreeBSD kernels with SO_ACCEPTFILTER enabled allows
- for a TCP DoS attack. Until there is a kernel fix, ISC is disabling
- SO_ACCEPTFILTER support in BIND. [RT #22589]
- </li><li class="listitem">
- Corrected a defect where a combination of dynamic updates and zone
- transfers incorrectly locked the in-memory zone database, causing
- named to freeze. [RT #22614]
- </li><li class="listitem">
- Don't run MX checks (check-mx) when the MX record points to ".".
- [RT #22645]
- </li><li class="listitem">
- DST key reference counts can now be incremented via dst_key_attach.

- isc_mutex_init_errcheck() in phtreads/mutex.c failed to destroy attr. [RT #22766]

- The Kerberos realm was being truncated when being pulled from the
- the host prinicipal, make krb5-self updates fail. [RT #22770]

- named failed to preserve the case of domain names in RDATA which is not compressible when writing master files. [RT #22863]
- </li><li class="listitem">
-There was a bug in how the clients-per-query code worked with some
-query patterns. This could result, in rare circumstances, in having all
-the client query slots filled with queries for the same DNS label,
-essentially ignoring the max-clients-per-query setting.

- Worked around a race condition in the cache database memory
- handling. Without this fix a DNS cache DB or ADB could
- incorrectly stay in an over memory state, effectively refusing
- further caching, which subsequently made a BIND 9 caching
- server unworkable.
- [RT #21818]
- </li><li class="listitem">
- Microsoft changed the behavior of sockets between NT/XP based
- stacks vs Vista/windows7 stacks. Server 2003/2008 have the older
- behavior, 2008r2 has the new behavior. With the change, different
- error results are possible, so ISC adapted BIND to handle the new
- error results.
- This resolves an issue where sockets would shut down on
- Windows servers causing named to stop responding to queries.
- [RT #21906]
- </li><li class="listitem">
- Windows has non-POSIX compliant behavior in its rename() and unlink()
- calls. This caused journal compaction to fail on Windows BIND servers
