MFC 253983, 253984:

Update Bind to 9.8.5-P2

New Features

Adds a new configuration option, "check-spf"; valid values are
"warn" (default) and "ignore". When set to "warn", checks SPF
and TXT records in spf format, warning if either resource record
type occurs without a corresponding record of the other resource
record type. [RT #33355]

Adds support for Uniform Resource Identifier (URI) resource
records. [RT #23386]

Adds support for the EUI48 and EUI64 RR types. [RT #33082]

Adds support for the RFC 6742 ILNP record types (NID, LP, L32,
and L64). [RT #31836]

Feature Changes

Changes timing of when slave zones send NOTIFY messages after
loading a new copy of the zone. They now send the NOTIFY before
writing the zone data to disk. This will result in quicker
propagation of updates in multi-level server structures. [RT #27242]
"named -V" can now report a source ID string. (This is will be
of most interest to developers and troubleshooters). The source

ID for ISC's production versions of BIND is defined in the "srcid"
file in the build tree and is normally set to the most recent
git hash. [RT #31494]

Response Policy Zone performance enhancements. New "response-policy"
option "min-ns-dots". "nsip" and "nsdname" now enabled by default
with RPZ. [RT #32251]

MFV/MFC r233914:

Update to version 9.8.2, the latest from ISC, which contains numerous bug fixes.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Upgrade to 9.6-ESV-R4-P1, which address the following issues:

1. Very large RRSIG RRsets included in a negative cache can trigger
an assertion failure that will crash named (BIND 9 DNS) due to an
off-by-one error in a buffer size check.

This bug affects all resolving name servers, whether DNSSEC validation
is enabled or not, on all BIND versions prior to today. There is a
possibility of malicious exploitation of this bug by remote users.

2. Named could fail to validate zones listed in a DLV that validated
insecure without using DLV and had DS records in the parent zone.

Add a patch provided by ru@ and confirmed by ISC to fix a crash at
shutdown time when a SIG(0) key is being used.

Update BIND to version 9.6.1rc1. This version has better performance and
lots of new features compared to 9.4.x, including:

Full NSEC3 support
Automatic zone re-signing
New update-policy methods tcp-self and 6to4-self
DHCID support.
More detailed statistics counters including those supported in BIND 8.
Faster ACL processing.
Efficient LRU cache-cleaning mechanism.
NSID support.
