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]
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]
Based on PR 41772 by Robert Elz.
Pkgsrc changes:
o MAKE_JOBS_SAFE=no, README said "Do not use a parallel make".
o remove patch-aj, libbind has been removed from the BIND 9 distribution
since 9.6.0.
o add bind-dig-sigchase option. requested by PR 41751.

2607. [bug] named could incorrectly delete NSEC3 records for
empty nodes when processing a update request.
[RT #19749]

2597. [bug] Handle a validation failure with a insecure delegation
from a NSEC3 signed master/slave zone. [RT #19464]
