<div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem">
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.
[RT #22288] [CVE-2010-3613] [VU#706148]
</li><li class="listitem">
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.

Check that named successfully skips NSEC3 records
that fail to match the NSEC3PARAM record currently
in use.
[RT #21868]
</li><li class="listitem">
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">
BIND did not properly handle non-cacheable negative responses
from insecure zones. This caused several non-protocol-compliant
zones to become unresolvable. BIND is now more accepting of
responses it receives from less strict servers.
[RT #21555]
</li><li class="listitem">
The resolver could attempt to destroy a fetch context too
soon, resulting in a crash.
[RT #19878]
</li><li class="listitem">
The placeholder negative caching element was not
properly constructed triggering a crash (INSIST) in
dns_ncache_towire().
[RT #21346]
</li><li class="listitem">
Handle the introduction of new trusted-keys and
DS, DLV RRsets better.

Fix arguments to dns_keytable_findnextkeynode() call.

<div class="itemizedlist"><ul class="itemizedlist" type="disc"><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
with the log error: "dns_journal_compact failed: failure".
[RT #22434]
</li><li class="listitem">
'host -D' now turns on debugging messages earlier.
[RT #22361]
</li><li class="listitem">
isc_print_vsnprintf() failed to check if there was
space available in the buffer when adding a left
justified character with a non zero width,
(e.g. "%-1c").
[RT #22270]
</li><li class="listitem">
view->queryacl was being overloaded. Seperate the
usage into view->queryacl, view->cacheacl and
view->queryonacl.
[RT #22114]

win32: add more dependencies to BINDBuild.dsw.

delegations.

<p>
"make test" will fail on OSX and possibly other operating systems.
The failure occurs in a new test to check for allow-query ACLs.
The failure is caused because the source address is not specified on
the dig commands issued in the test.
</p>
<p>
If running "make test" is part of your usual acceptance process,
please edit the file <code class="code">bin/tests/system/allow_query/test.sh</code>
and add
</p><p>
<code class="code">-b 10.53.0.2</code>
</p><p>
to the <code class="code">DIGOPTS</code> line.
