[SECURITY] Fedora 26 Update: knot-resolver-2.1.0-1.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: If you run into issues with activation of the service or its sockets, either update your selinux-policy package or turn off selinux (setenforce 0). https://bugzilla.redhat.com/show_bug.cgi?id=3D1366968 https://bugzilla.redhat.com/show_bug.cgi?id=3D1543049
