Several bugs have been fixed in the RPZ implementation:
|
|
</para>
|
|
<itemizedlist>
|
|
<para>
|
|
Policy zones that did not specifically require recursion
|
|
could be treated as if they did; consequently, setting
|
|
<command>qname-wait-recurse no;</command> was
|
|
sometimes ineffective. This has been corrected.
|
|
In most configurations, behavioral changes due to this
|
|
fix will not be noticeable. [RT #39229]
|
|
</para>

|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
The server could crash if policy zones were updated (e.g.
|
|
via <command>rndc reload</command> or an incoming zone
|
|
transfer) while RPZ processing was still ongoing for an
|
|
active query. [RT #39415]

|
|
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]

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]
