libunbound-devel-mini-1.16.0-1.1 RPM for ppc64

From OpenSuSE Ports Tumbleweed for ppc64

Name: libunbound-devel-mini Distribution: openSUSE Tumbleweed
Version: 1.16.0 Vendor: openSUSE
Release: 1.1 Build date: Sun Jun 19 21:29:03 2022
Group: Productivity/Networking/DNS/Servers Build host: obs-power9-10
Size: 1305098 Source RPM: libunbound-devel-mini-1.16.0-1.1.src.rpm
Summary: Just a devel package for build loops
Unbound is a validating, recursive, and caching DNS(SEC) resolver.

The C implementation of Unbound is developed and maintained by NLnet
Labs. It is based on ideas and algorithms taken from a java prototype
developed by Verisign labs, Nominet, Kirei and

Unbound is designed as a set of modular components, so that also
DNSSEC (secure DNS) validation and stub-resolvers (that do not run
as a server, but are linked into an application) are easily possible.

  - update to 1.9.6
    This release contains a number of security related fixes found in
    a security audit
  - The unbound.conf includes are sorted ascending, for include
    statements with a '*' from glob.
  - drop-tld.diff in contrib/ : adds option drop-tld: yesno that drops 2 label
    queries, to stop random floods.  Apply with
    patch -p1 < contrib/drop-tld.diff and compile.
    From Saksham Manchanda (Secure64).  Please note that we think this
    will drop DNSKEY and DS lookups for tlds and hence break DNSSEC
    lookups for downstream clients.
  - Add new configure option `--enable-fully-static` to enable full static
    build if requested; in relation to #91.
  - Add make distclean that removes everything configure produced,
    and make maintainer-clean that removes bison and flex output.
  - unbound-fuzzers.tar.bz2 in contrib/ : three programs for fuzzing, that
    are 1:1 replacements for unbound-fuzzme.c that gets created after applying
    the contrib/unbound-fuzzme.patch.  They are contributed by
    Eric Sesterhenn from X41 D-Sec.

    there is a high volume and the operator cannot do anything for the
    remote failure.  Specifically filters the high volume errors.
  - Fix #71: fix openssl error squelch commit compilation error.
  - Fix #72: configure --with-syslog-facility=LOCAL0-7 with default
