Types

type ConnAdapter 

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

ConnAdapter wraps a PPP connection into the etherconn.SharedEthernetConn interface.

func NewConnAdapter 

func NewConnAdapter(ppp *PPP, proto ProtocolNumber) *ConnAdapter

func (*ConnAdapter) Close 

func (c *ConnAdapter) Close() error

func (*ConnAdapter) Register 

func (c *ConnAdapter) Register(k etherconn.L4HashKey) (torecvch chan *etherconn.EthernetResponse)

func (*ConnAdapter) SetWriteDeadline 

func (c *ConnAdapter) SetWriteDeadline(t time.Time) error

SetWriteDeadline sets deadline for WriteIPPktTo

func (*ConnAdapter) Start 

func (c *ConnAdapter) Start(ctx context.Context)

func (*ConnAdapter) Unregister added in v1.1.0 

func (c *ConnAdapter) Unregister(k etherconn.L4HashKey)

func (*ConnAdapter) WriteIPPktTo 

func (c *ConnAdapter) WriteIPPktTo(p []byte, _ net.HardwareAddr) (int, error)

WriteIPPktTo implements etherconn.SharedEthernetConn interface. dstmac is not used at all.

type Deserializer 

type Deserializer interface {
	Parse([]byte) error
}

type PPP 

type PPP struct {
	Logger *zerolog.Logger
	// contains filtered or unexported fields
}

PPP represents the PPP protocol (built over PPPoE for usage over ethernet)

func NewPPP 

func NewPPP(conn net.PacketConn, l *zerolog.Logger, generateReject func(b []byte) *Packet) *PPP

NewPPP creates a new PPP protocol instance, using conn as underlying transport, l as Logger;

func (*PPP) Close 

func (ppp *PPP) Close() error

func (*PPP) Register 

func (ppp *PPP) Register(p ProtocolNumber) (chan []byte, chan []byte)

Register a new protocol over PPP. 1. send is used to send packets 2. receive is used to receive packets

func (*PPP) Start 

func (ppp *PPP) Start(ctx context.Context)

func (*PPP) Unregister 

func (ppp *PPP) Unregister(p ProtocolNumber)

Unregister removes a previously registered protocol if present.

type Packet 

type Packet struct {
	Proto   ProtocolNumber
	Payload Serializer
}

Packet represents PPP packet

func NewPacket 

func NewPacket(data Serializer, proto ProtocolNumber) *Packet

NewPacket return a new PPP packet with protocol number and payload

func (*Packet) Parse 

func (pppPkt *Packet) Parse(buf []byte) error

Parse buf into PPPPacket

func (*Packet) Serialize 

func (pppPkt *Packet) Serialize() ([]byte, error)

Serialize into bytes, without copying, and no padding

type ProtocolNumber 

type ProtocolNumber uint16

ProtocolNumber is the PPP protocol number
