[SECURITY] Fedora 26 Update: knot-resolver-2.3.0-1.fc26

The Knot DNS Resolver is a caching full resolver implementation written in C and LuaJIT, including both a resolver library and a daemon. Modular architecture of the library keeps the core tiny and efficient, and provides a state-machine like API for extensions. The package is pre-configured as local caching resolver. To start using it, start a single kresd instance: $ systemctl start kresd(a)1.service
