   Log Message:
   Update bind96 package to 9.6.3.

   9.6.3

        * BIND now builds with threads disabled in versions of NetBSD earlier
          than 5.0 and with pthreads enabled by default in NetBSD versions
          5.0 and higher. Also removes support for unproven-pthreads,
          mit-pthreads and ptl2. [RT #19203]
        * HPUX now correctly defaults to using /dev/poll, which should
          increase performance. [RT #21919]
        * If named is running as a threaded application, after an "rndc stop"
          command has been issued, other inbound TCP requests can cause named
          to hang and never complete shutdown. [RT #22108]
        * When performing a GSS-TSIG signed dynamic zone update, memory could
          be leaked. This causes an unclean shutdown and may affect
          long-running servers. [RT #22573]
        * A bug in NetBSD and FreeBSD kernels with SO_ACCEPTFILTER enabled
          allows for a TCP DoS attack. Until there is a kernel fix, ISC is
          disabling SO_ACCEPTFILTER support in BIND. [RT #22589]
        * Corrected a defect where a combination of dynamic updates and zone
          transfers incorrectly locked the in-memory zone database, causing
          named to freeze. [RT #22614]
        * Don't run MX checks (check-mx) when the MX record points to ".".
          [RT #22645]
        * DST key reference counts can now be incremented via dst_key_attach.
          [RT #22672]
        * isc_mutex_init_errcheck() in phtreads/mutex.c failed to destroy
          attr. [RT #22766]
        * The Kerberos realm was being truncated when being pulled from the
          the host prinicipal, make krb5-self updates fail. [RT #22770]
        * named failed to preserve the case of domain names in RDATA which is
          not compressible when writing master files. [RT #22863]
        * There was a bug in how the clients-per-query code worked with some
          query patterns. This could result, in rare circumstances, in having
          all the client query slots filled with queries for the same DNS
          label, essentially ignoring the max-clients-per-query setting. [RT
          #22972]
