DNS BIND今天放出各产品线的最新版本9.9.4,9.8.6.2013-09-20.进过2个RC.之前的版本是2013-05-28的9.9.3/9.8.5。尽管BIND 10已经发布1.1，但因为改动太大，可能更多使用的还是BIND9.9.9.4支持了RRL防止DOS攻击。
完全改进：
Security Fixes
Previously an error in bounds checking on the private type
'keydata' could be used to deny service through a deliberately
triggerable REQUIRE failure (CVE-2013-4854). [RT #34238]
Prevents exploitation of a runtime_check which can crash named
when satisfying a recursive query for particular malformed zones.
(CVE-2013-3919) [RT #33690]
New Features
Added Response Rate Limiting (RRL) functionality to reduce the
effectiveness of DNS as an amplifier for reflected denial-of-service
attacks by rate-limiting substantially-identical responses. [RT
#28130]
Feature Changes
rndc status now also shows the build-id. [RT #20422]
Improved OPT pseudo-record processing to make it easier to support
new EDNS options. [RT #34414]
"configure" now finishes by printing a summary of optional BIND
features and whether they are active or inactive. ("configure
--enable-full-report" increases the verbosity of the summary.)
[RT #31777]
Addressed compatibility issues with newer versions of Microsoft
Visual Studio. [RT #33916]
Improved the 'rndc' man page. [RT #33506]
'named -g' now no longer works with an invalid logging configuration.
[RT #33473]
The default (and minimum) value for tcp-listen-queue is now 10
instead of 3. This is a subtle control setting (not applicable
to all OS environments). When there is a high rate of inbound
TCP connections, it controls how many connections can be queued
before they are accepted by named. Once this limit is exceeded,
new TCP connections will be rejected. Note however that a value
of 10 does not imply a strict limit of 10 queued TCP connections
- the impact of changing this configuration setting will be
OS-dependent. Larger values for tcp-listen queue will permit
more pending tcp connections, which may be needed where there
is a high rate of TCP-based traffic (for example in a dynamic
environment where there are frequent zone updates and transfers).
For most production servers the new default value of 10 should
be adequate. [RT #33029]
Added support for OpenSSL versions 0.9.8y, 1.0.0k, and 1.0.1e
with PKCS#11. [RT #33463]
Added logging messages on slave servers when they forward DDNS
updates to a master. [RT #33240]
Changed the logging category for RRL events from 'queries' to
'query-errors'. [RT #33540]
Bug Fixes
Fixed the "allow-query-on" option to correctly check the destination
address. [RT #34590]
Fix forwarding for forward only "zones" beneath automatic empty
zones. [RT #34583]
Fix DNSSEC auto maintenance so signatures can be removed from a
zone with only KSK keys for an algorithm. [RT #34439]
Fix DNSSEC auto maintenance so signatures from newly inactive
keys are removed (when publishing a new key while deactivating
another key at the same time). [RT #32178]
Remove bogus warning log message about missing signatures when
receiving a query for a SIG record. [RT #34600]
Fix Response Policy Zones on slave servers so new RPZ changes
take effect. [RT #34450]
Fix the "zone-statistics" option to work with the default
traditional statistics (not new "--enable-newstats" feature).
[RT #34466]
named could crash when deleting inline-signing zones with "rndc
delzone". [RT #34066]
Improved resistance to a theoretical authentication attack based
on differential timing. [RT #33939]
named was failing to answer queries during "rndc reload" [RT
#34098]
win32: Some executables had been omitted from the installer. [RT
#34116]
fixed a broken 'Invalid keyfile' error message in dnssec-keygen.
[RT #34045]
The build of BIND now installs isc/stat.h so that it's available
to /isc/file.h when building other applications that reference
these header files - for example dnsperf (see Debian bug ticket
#692467). [RT #33056]
Better handle failures building XML for stats channel responses.
[RT #33706]
Fixed a memory leak in GSS-API processing. [RT #33574]
Fixed an acache-related race condition that could cause a crash.
[RT #33602]
rndc now properly fails when given an invalid '-c' argument. [RT
#33571]
Fixed an issue with the handling of zero TTL records that could
cause improper SERVFAILs. [RT #33411]
Fixed a crash-on-shutdown race condition with DNSSEC validation.
[RT #33573]
Corrected the way that "rndc addzone" and "rndc delzone" handle
non-standard characters in zone names. [RT #33419]
Adjusted RRL behavior for recursive queries to defer rate-limiting
until after recursion is complete. Also uses correct rcode for
slipped NXDOMAIN responses. [RT #33604]
Previously, BIND could erroneously report a missing file
specification when using inline slave zones. [RT #33662]
