EXPIRATION_DATE=        2011-01-01

While I'm here, update CONFLICTS for bind98.

Actually remove the MD5, oops

For the port:
1. Add CONFLICT for the ../bind-tools port
2. Remove CONFLICT for the removed ../bind9 port
3. Remove OPTION for threads on < RELENG_7
4. Remove MD5 from distinfo
5. Switch to pkg-install to create the symlinks to /etc/namedb/ as
   requested in [1]

Update to the latest patch set from ISC, which addresses the following:

   Named could return SERVFAIL for negative responses
   from unsigned zones.

Update to the latest patchfix releases to deal with the problems
related to the handling of broken DNSSEC trust chains.

This fix is only necessary for those who have DNSSEC validation
enabled and configure trust anchors from third parties, either
manually, or through a system like DLV.

Upgrade to BIND 9.4.3-P5, 9.5.2-P2, and 9.6.1-P3. These versions address
the following vulnerabilities:

BIND 9 Cache Update from Additional Section
https://www.isc.org/advisories/CVE-2009-4022v6
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-4022
A nameserver with DNSSEC validation enabled may incorrectly add
unauthenticated records to its cache that are received during the
resolution of a recursive client query

BIND 9 DNSSEC validation code could cause bogus NXDOMAIN responses
https://www.isc.org/advisories/CVE-2010-0097
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0097
There was an error in the DNSSEC NSEC/NSEC3 validation code that could
cause bogus NXDOMAIN responses (that is, NXDOMAIN responses for records
proven by NSEC or NSEC3 to exist) to be cached as if they had validated
correctly

These issues only affect systems with DNSSEC validation enabled.

Update CONFLICTS for bind97

Update to the latest patchlevels for BINDs 9.[456]. The vulnerability
this is designed to fix is related to DNSSEC validation on a resolving
name server that allows access to untrusted users. If your system does
not fall into all 3 of these categories you do not need to update
immediately.

Wrap some query socket handling in dig with a socket != NULL bow

This patch or something similar will likely be included in a future
BIND release.

Add isc-config.sh.1 to MAN1

Feature safe:   yes

Update to version 9.5.2, the latest from ISC. This version has numerous
bug fixes, and all users of BIND 9.5.x are encouraged to upgrade.

Feature safe:   yes

The new LINKS OPTION is not only useless it's harmful when combined
with the REPLACE_BASE option so if the latter is defined don't try
to make the LINKS.

Problem pointed out by: Chris Wopat <me@falz.net>

For all:
Add an OPTION (on by default) to install the appropriate symlinks for
named.conf and rndc.key in /usr/local/etc and /var/named/usr/local/etc.

For bind9[456]:
Add OPTIONs (off by default) for the DLZ configure options, and their
corresponding ports knobs. [1] The basic infrastructure for this was
provided in the PR, but this version is slightly different in a few
details so responsibility for bugs is mine.

Update the hashes of the PGP signature files for the new releases.
The previous signatures were derived from the wrong key.
The new signatures all verify correctly.

No changes to the hashes for the software itself.

Update to patched versions which address a remote DoS vulnerability:

        Receipt of a specially-crafted dynamic update message may
        cause BIND 9 servers to exit. This vulnerability affects all
        servers -- it is not limited to those that are configured to
        allow dynamic updates. Access controls will not provide an
        effective workaround.

More details can be found here: https://www.isc.org/node/474

All BIND users are encouraged to update to a patched version ASAP.

- Flip from MAKE_JOBS_SAFE to MAKE_JOBS_UNSAFE, fails both on pointyhat and on
  my local machine

Fix CONFLICTS (again). The previous example didn't work at all for ports
other than plain bind9 since the real PORTNAMEs for the other ports are
bind9[456]. This fix has the added advantage of covering REPLACE_BASE.

Where it matters, update regarding MAKE_JOBS_{UN}SAFE for my ports

BIND 9.5.1-P2 is a SECURITY patch for BIND 9.5.1.  It addresses a bug
in DNSSEC lookaside validation (DLV): unrecognized signature algorithms,
which should have been treated as the equivalent of an unsigned zone,
were instead treated as a validation failure.

Update to the -P1 versions of the current BIND ports which contain
the fix for the following vulnerability: https://www.isc.org/node/373

Description:
Return values from OpenSSL library functions EVP_VerifyFinal()
and DSA_do_verify() were not checked properly.

Impact:
It is theoretically possible to spoof answers returned from
zones using the DNSKEY algorithms DSA (3) and NSEC3DSA (6).

In short, if you're not using DNSSEC to verify signatures you have
nothing to worry about.

While I'm here, address the issues raised in the PR by adding a knob
to disable building with OpenSSL altogether (which eliminates DNSSEC
capability), and fix the configure arguments to better deal with the
situation where the user has ssl bits in both the base and LOCALBASE.

Update CONFLICTS to reflect the addition of the bind96 port,
the demise of bind9-dlz, and updates to the bind9-sdb-* ports.

Upgrade to version 9.5.1 which includes numerous bug fixes and performance
improvements, including, "Additional support for query port randomization
including performance improvement and port range specification."

When building on amd64 ports' configure doesn't properly recognize our
arch, so help it along a bit. [1]

Update to patchlevel 2 for all versions:

- performance improvement over the P1 releases, namely
   + significantly remedying the port allocation issues
   + allowing TCP queries and zone transfers while issuing as many
      outstanding UDP queries as possible
   + additional security of port randomization at the same level as P1

- also includes fixes for several bugs in the 9.5.0 base code

Add an OPTION to turn on the ability of dns/host/nslookup to do
DNSSEC validation.

This is off by default, so no PORTREVISION bump.

Strengthen the wording regarding the THREADS OPTION for <FreeBSD-7

Upgrade to the -P1 versions of each port, which add stronger randomization
of the UDP query-source ports. The server will still use the same query
port for the life of the process, so users for whom the issue of cache
poisoning is highly significant may wish to periodically restart their
server using /etc/rc.d/named restart, or other suitable method.

In order to take advantage of this randomization users MUST have an
appropriate firewall configuration to allow UDP queries to be sent and
answers to be received on random ports; and users MUST NOT specify a
port number using the query-source[-v6] option.

The avoid-v[46]-udp-ports options exist for users who wish to eliminate
certain port numbers from being chosen by named for this purpose. See
the ARM Chatper 6 for more information.

Update for 9.5.0

Some of the important features of BIND 9 are:

DNS Security: DNSSEC (signed zones), TSIG (signed DNS requests)
IP version 6: Answers DNS queries on IPv6 sockets, IPv6 resource records (AAAA)
     Experimental IPv6 Resolver Library
DNS Protocol Enhancements: IXFR, DDNS, Notify, EDNS0
     Improved standards conformance
Views: One server process can provide multiple "views" of the DNS namespace,
     e.g. an "inside" view to certain clients, and an "outside" view to others.
Multiprocessor Support, including working threads in this version

BIND 9.5 has a number of new features over previous versions, including:
GSS-TSIG support (RFC 3645), DHCID support
Experimental http server and statistics support for named via xml
More detailed statistics counters, compatible with the ones supported in BIND 8
Faster ACL processing
Efficient LRU cache cleaning mechanism.
NSID support (RFC 5001).
