This document summarizes changes since BIND 9.10.2.
|
|
</p>
|
|
<p>
|
|
BIND 9.10.2-P1 addresses several bugs that have been identified
|
|
in the BIND 9.10 implementation of response-policy zones (RPZ).
|
|
The bugs are in code which optimizes searching through multiple
|
|
policy zones. In some cases, they can cause RPZ to behave
|
|
inefficiently by searching for query matches in more policy
|
|
zones than are strictly necessary, or to behave unpredictably
|
|
by failing to search a policy zone that should have been
|
|
searched. In the worst case, they can lead to assertion
|
|
failures, terminating <span><strong class="command">named</strong></span>.
|
|
</p>
|
|
<p>
|
|
If you are using RPZ in BIND 9.10 in a production environment,
|
|
and particularly if you have multiple policy zones, you should
|
|
upgrade to BIND 9.10.2-P1. Otherwise, this upgrade is not urgent.

<div class="itemizedlist"><ul type="disc"><li>
|
|
<p>
|
|
Several bugs have been fixed in the RPZ implementation:
|
|
</p>
|
|
<div class="itemizedlist"><ul type="circle">
|
|
<li><p>
|
|
Policy zones that did not specifically require recursion
|
|
could be treated as if they did; consequently, setting
|
|
<span><strong class="command">qname-wait-recurse no;</strong></span> was
|
|
sometimes ineffective. This has been corrected.
|
|
In most configurations, behavioral changes due to this
|
|
fix will not be noticeable. [RT #39229]
|
|
</p></li>
|
|
<li><p>
|
|
The server could crash if policy zones were updated (e.g.
|
|
via <span><strong class="command">rndc reload</strong></span> or an incoming zone
|
|
transfer) while RPZ processing was still ongoing for an
|
|
active query. [RT #39415]
|
|
</p></li>
|
|
<li><p>
|
|
On servers with one or more policy zones configured as
|
|
slaves, if a policy zone updated during regular operation
|
|
(rather than at startup) using a full zone reload, such as
|
|
via AXFR, a bug could allow the RPZ summary data to fall out
|
|
of sync, potentially leading to an assertion failure in
|
|
rpz.c when further incremental updates were made to the
|
|
zone, such as via IXFR. [RT #39567]
|
|
</p></li>
|
|
<li><p>
|
|
The server could match a shorter prefix than what was
|
|
available in CLIENT-IP policy triggers, and so, an
|
|
unexpected action could be taken. This has been
|
|
corrected. [RT #39481]
|
|

The end of life for BIND 9.10 is yet to be determined but
|
|
will not be before BIND 9.12.0 has been released for 6 months.
