Types

type DotSegmentIterator

type DotSegmentIterator struct {
	// contains filtered or unexported fields
}

func NewDotSegmentRevertIterator

func NewDotSegmentRevertIterator(value string) *DotSegmentIterator

func (*DotSegmentIterator) HasNext

func (iterator *DotSegmentIterator) HasNext() bool

func (*DotSegmentIterator) Next

func (iterator *DotSegmentIterator) Next() int

func (*DotSegmentIterator) NextIdx

func (iterator *DotSegmentIterator) NextIdx() int

type IPSet

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

IPSet implements the plugin interface.

func New

func New() *IPSet

New create new ipset

func (IPSet) Name

func (p IPSet) Name() string

Name implements the Handler interface.

func (IPSet) ServeDNS

func (p IPSet) 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, ipset *IPSet) *ResponseReverter

NewResponseReverter returns a pointer to a new ResponseReverter.

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.

type StringSegment

type StringSegment func(key string, start int) (segment string, nextIndex int)

type Trie

type Trie struct {
	// contains filtered or unexported fields
}

func NewTrie

func NewTrie(key string) *Trie

func (*Trie) Get

func (trie *Trie) Get(key string) int

func (*Trie) Put

func (trie *Trie) Put(key string, value int)
