Functions ¶

func Size ¶

func Size(proto string, size int) int

Size returns a normalized size based on proto.

func Version ¶

func Version(req *dns.Msg) (*dns.Msg, error)

Version checks the EDNS version in the request. If error is nil everything is OK and we can invoke the plugin. If non-nil, the returned Msg is valid to be returned to the client (and should). For some reason this response should not contain a question RR in the question section.

Types ¶
