net/bind918: update to 9.18.11

Approved by MAINTAINER (sekiya@).

--- 9.18.11 released ---

6067. [security] Fix serve-stale crash when recursive clients soft quota
is reached. (CVE-2022-3924) [GL #3619]

6066. [security] Handle RRSIG lookups when serve-stale is active.
(CVE-2022-3736) [GL #3622]

6064. [security] An UPDATE message flood could cause named to exhaust all
available memory. This flaw was addressed by adding a
new "update-quota" statement that controls the number of
simultaneous UPDATE messages that can be processed or
forwarded. The default is 100. A stats counter has been
added to record events when the update quota is
exceeded, and the XML and JSON statistics version
numbers have been updated. (CVE-2022-3094) [GL #3523]

6062. [func] The DSCP implementation, which has been
nonfunctional for some time, is now marked as
obsolete and the implementation has been removed.
Configuring DSCP values in named.conf has no
effect, and a warning will be logged that
the feature should no longer be used. [GL #3773]

6061. [bug] Fix unexpected "Prohibited" extended DNS error
on allow-recursion. [GL #3743]

6060. [bug] Fix a use-after-free bug in dns_zonemgr_releasezone()
by detaching from the zone manager outside of the write
lock. [GL #3768]

6059. [bug] In some serve stale scenarios, like when following an
expired CNAME record, named could return SERVFAIL if the
previous request wasn't successful. Consider non-stale
data when in serve-stale mode. [GL #3678]

6058. [bug] Prevent named from crashing when "rndc delzone"
attempts to delete a zone added by a catalog zone.
[GL #3745]

6053. [bug] Fix an ADB quota management bug in resolver. [GL #3752]

6051. [bug] Improve thread safety in the dns_dispatch unit.
[GL #3178] [GL #3636]

6050. [bug] Changes to the RPZ response-policy min-update-interval
and add-soa options now take effect as expected when
named is reconfigured. [GL #3740]

6049. [bug] Exclude ABD hashtables from the ADB memory
overmem checks and don't clean ADB names
and ADB entries used in the last 10 seconds
(ADB_CACHE_MINIMUM). [GL #3739]

6048. [bug] Fix a log message error in dns_catz_update_from_db(),
where serials with values of 2^31 or larger were logged
incorrectly as negative numbers. [GL #3742]

6047. [bug] Try the next server instead of trying the same
server again on an outgoing query timeout.
[GL #3637]

6046. [bug] TLS session resumption might lead to handshake
failures when client certificates are used for
authentication (Mutual TLS).  This has been fixed.
[GL #3725]

6045. [cleanup] The list of supported DNSSEC algorithms changed log
level from "warning" to "notice" to match named's other
startup messages. [GL !7217]

6044. [bug] There was an "RSASHA236" typo in a log message.
[GL !7206]

5830. [func] Implement incremental resizing of isc_ht hash tables to
perform the rehashing gradually. The catalog zone
implementation has been optimized to work with hundreds
of thousands of member zones. [GL #3212] [GL #3744]
