Overview ¶

Package ipv4 provides a thin, allocation-free view over raw IPv4 packets.

Functions ¶

func ScanFrame ¶

func ScanFrame(data []byte, atEof bool) (advance int, token []byte, err error)

ScanFrame implements bufio.SplitFunc to split a stream into IPv4 frames.

Types ¶

type Frame ¶

type Frame []byte

Frame is a raw IPv4 packet. Accessors read directly from the backing slice, so a Frame must be validated with DecodeFrame (or produced by MakeFrame or ScanFrame) before its variable-length fields are used.

func DecodeFrame ¶

func DecodeFrame(data []byte) Frame

func MakeFrame ¶

func MakeFrame(source, destination net.IP) Frame

func (Frame) Copy ¶

func (self Frame) Copy() Frame

func (Frame) DSCP ¶

func (self Frame) DSCP() byte

func (Frame) Destination ¶

func (self Frame) Destination() net.IP

func (Frame) DestinationPort ¶

func (self Frame) DestinationPort() uint16

func (Frame) ECN ¶

func (self Frame) ECN() byte

func (Frame) Flags ¶

func (self Frame) Flags() byte

func (Frame) FragmentOffset ¶

func (self Frame) FragmentOffset() uint16

func (Frame) HeaderChecksum ¶

func (self Frame) HeaderChecksum() uint16

func (Frame) IHL ¶

func (self Frame) IHL() byte

func (Frame) Identification ¶

func (self Frame) Identification() uint16

func (Frame) Options ¶

func (self Frame) Options() []byte

func (Frame) Payload ¶

func (self Frame) Payload() []byte

func (Frame) Protocol ¶

func (self Frame) Protocol() byte

func (Frame) SetDestination ¶

func (self Frame) SetDestination(ip net.IP)

func (Frame) SetIHL ¶

func (Frame) SetTotalLength ¶

func (self Frame) SetTotalLength(totalLength uint16)

func (Frame) SetVersion ¶

func (self Frame) SetVersion(version byte)

func (Frame) Source ¶

func (self Frame) Source() net.IP

func (Frame) SourcePort ¶

func (self Frame) SourcePort() uint16

func (Frame) TTL ¶

func (self Frame) TTL() byte

func (Frame) TotalLength ¶
