New quotas have been added to limit the queries that are
|
||
sent by recursive resolvers to authoritative servers
|
||
experiencing denial-of-service attacks. When configured,
|
||
these options can both reduce the harm done to authoritative
|
||
servers and also avoid the resource exhaustion that can be
|
||
experienced by recursives when they are being used as a
|
||
vehicle for such an attack.
|

</p>

<p>
|

NOTE: These options are not available by default; use

simultaneous queries that can be sent to any single

authoritative server. The configured value is a starting
|
||
point; it is automatically adjusted downward if the server is
|
||
partially or completely non-responsive. The algorithm used to
|
||
adjust the quota can be configured via the
|

<code class="option">fetch-quota-params</code> option.

<li><p>
|

<code class="option">fetches-per-zone</code> limits the number of

value is not self-tuning.)

Large inline-signing changes should be less disruptive.

"request-sit", "sit-secret" and "nosit-udp-size", are

"cookie-secret" and "nocookie-udp-size" in BIND 9.11.

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]
|
||
</p></li>
|
||
<li><p>
|
||
The server could crash if a reload of an RPZ zone was
|
||
initiated while another reload of the same zone was
|
||
already in progress. [RT #39649]
|
||
</p></li>
|
||
<li><p>
|
||
Query names could match against the wrong policy zone
|
||
if wildcard records were present. [RT #40357]
