Types

type N

type N struct {
	Next plugin.Handler
	// contains filtered or unexported fields
}

N implements the plugin interface.

func (N) Name

func (n N) Name() string

Name implements the Handler interface.

func (N) ServeDNS

func (n N) ServeDNS(ctx context.Context, w dns.ResponseWriter, r *dns.Msg) (int, error)

ServeDNS implements the plugin.Handler interface.

type ResponseReverter

type ResponseReverter struct {
	dns.ResponseWriter
	// contains filtered or unexported fields
}

ResponseReverter reverses the operations done on the question section of a packet. This is need because the client will otherwise disregards the response, i.e. dig will complain with ';; Question section mismatch: got example.org/HINFO/IN'

func NewResponseReverter

func NewResponseReverter(w dns.ResponseWriter, r *dns.Msg, listNames []string, mappedListName map[string][]string) *ResponseReverter

NewResponseReverter returns a pointer to a new ResponseReverter.

func (*ResponseReverter) HitDomainList

func (r *ResponseReverter) HitDomainList(domain string, domains []string) bool

func (*ResponseReverter) Write

func (r *ResponseReverter) Write(buf []byte) (int, error)

Write is a wrapper that records the size of the message that gets written.

func (*ResponseReverter) WriteMsg

func (r *ResponseReverter) WriteMsg(res *dns.Msg) error

WriteMsg records the status code and calls the underlying ResponseWriter's WriteMsg method.
