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
* 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]
* 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]
* 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]
Security Fixes
+ BIND 9 nameservers performing recursive queries could cache an
invalid record and subsequent queries for that record could
crash the resolvers with an assertion failure. [RT #26590]
[CVE-2011-4313]
Feature Changes
+ Improves initial start-up and server reload time by increasing
the default size of the hash table the configuration parser
uses to keep track of loaded zones and allowing it to grow
dynamically to better handle systems with large numbers of
zones. [RT #26523]
+ --enable-developer, a new composite argument to the configure
script, enables a set of build options normally disabled but
frequently selected in test or development builds, specifically:
enable_fixed_rrset, with_atf, enable_filter_aaaa, enable_rpz_nsip,
enable_rpz_nsdname, and with_dlz_filesystem (and on Linux and
Darwin, also enable_exportlib) [RT #27103]
* BIND 9 nameservers performing recursive queries could cache an invalid
record and subsequent queries for that record could crash the resolvers
with an assertion failure. [RT #26590]

New Features
9.6-ESV-R5
* Added a tool able to generate malformed packets to allow testing of
how named handles them. [RT #24096]
Security Fixes
9.6-ESV-R5
* named, set up to be a caching resolver, is vulnerable to a user
querying a domain with very large resource record sets (RRSets)
when trying to negatively cache the response. Due to an off-by-one
error, caching the response could cause named to crash. [RT #24650]
[CVE-2011-1910]
* Change #2912 populated the message section in replies to UPDATE
requests, which some Windows clients wanted. This exposed a latent
bug that allowed the response message to crash named. With this
fix, change 2912 has been reduced to copy only the zone section to
the reply. A more complete fix for the latent bug will be released
later. [RT #24777]
Feature Changes
9.6-ESV-R5
* Merged in the NetBSD ATF test framework (currently version 0.12)
for development of future unit tests. Use configure --with-atf to
build ATF internally or configure --with-atf=prefix to use an
external copy. [RT #23209]
* Added more verbose error reporting from DLZ LDAP. [RT #23402]
* Replaced compile time constant with STDTIME_ON_32BITS. [RT #23587]
The package name was selected as:
- Make sure to greater version from bind-9.6.3.

9.6.3
* 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]
* HPUX now correctly defaults to using /dev/poll, which should
increase performance. [RT #21919]
* 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]
* 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]
* 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]
* 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]
* Don't run MX checks (check-mx) when the MX record points to ".".
[RT #22645]
* DST key reference counts can now be incremented via dst_key_attach.
[RT #22672]
* 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]
* 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. [RT
#22972]
--- 9.6.1-P3 released ---
2831. [security] Do not attempt to validate or cache
out-of-bailiwick data returned with a secure
answer; it must be re-fetched from its original
source and validated in that context. [RT #20819]
2828. [security] Cached CNAME or DNAME RR could be returned to clients
without DNSSEC validation. [RT #20737]
2827. [security] Bogus NXDOMAIN could be cached as if valid. [RT #20712]
--- 9.6.1-P2 released ---
2772. [security] When validating, track whether pending data was from
the additional section or not and only return it if
validates as secure. [RT #20438]

2578. [bug] Changed default sig-signing-type to 65534, because

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
