Erwin Lansing cfd4d2c42e Update to 9.8.4-P1. 
Security Fixes

   Prevents named from aborting with a require assertion failure
   on servers with DNS64 enabled.  These crashes might occur as a
   result of  specific queries that are received.

New Features

*  Elliptic Curve Digital Signature Algorithm keys and signatures in
   DNSSEC are now supported per RFC 6605. [RT #21918]

Feature Changes

*  Improves OpenSSL error logging [RT #29932]

*  nslookup now returns a nonzero exit code when it is unable to get
   an answer.  [RT #29492]

Other critical bug fixes are included.

# So ... if none of --prefix, --sysconfdir or --localstatedir are

# it for sysconfdir and localstatedir the way configure normally
# would. To change the prefix for everything but leave named.conf
# in /etc or named.pid in /var/run, then do this the usual configure way:
# ./configure --prefix=/somewhere --sysconfdir=/etc
# ./configure --prefix=/somewhere --localstatedir=/var
#
# To put named.conf and named.pid in /usr/local with everything else,
# set the prefix explicitly to /usr/local even though that's the default:

# XXXDCL This probably doesn't work right on all systems.

# Essentially the problems here relate to two different
# areas. The first area is building with either KTH
# or MIT Kerberos, particularly when both are present on
# the machine. The other is static versus dynamic linking.
#
# On the KTH vs MIT issue, Both have libkrb5 that can mess
# up the works if one implementation ends up trying to
# use the other's krb. This is unfortunately a situation
# that very easily arises.
#
# Dynamic linking when the dependency information is built
# into MIT's libgssapi_krb5 or KTH's libgssapi magically makes
# all such problems go away, but when that setup is not
# present, because either the dynamic libraries lack
# dependencies or static linking is being done, then the
# problems start to show up.
