Functions

func AfpacketDecoderEngine

func AfpacketDecoderEngine(ifaceName string, filter string, ctx context.Context)

func DefaultEagerEngine

func DefaultEagerEngine(ifaceName string, filter string, ctx context.Context)

func LayerDump

func LayerDump(l gopacket.Layer) string

LayerDump outputs a very verbose string representation of a layer. Its output is a concatenation of LayerString(l) and hex.Dump(l.LayerContents()). It contains newlines and ends with a newline.

func ZeroCopyDecoderEngine

func ZeroCopyDecoderEngine(ifaceName string, filter string, ctx context.Context)

func ZeroCopyEagerEngine

func ZeroCopyEagerEngine(ifaceName string, filter string, ctx context.Context)

func ZeroCopyEagerWithChannelEngine

func ZeroCopyEagerWithChannelEngine(ifaceName string, filter string, ctx context.Context)

func ZeroCopyPacketBuilderEngine

func ZeroCopyPacketBuilderEngine(ifaceName string, filter string, ctx context.Context)

func ZeroCopyParserEngine

func ZeroCopyParserEngine(ifaceName string, filter string, ctx context.Context)

Types

type DecodeFailure

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

DecodeFailure is a packet layer created if decoding of the packet data failed for some reason. It implements ErrorLayer. LayerContents will be the entire set of bytes that failed to parse, and Error will return the reason parsing failed.

func (*DecodeFailure) Dump

func (d *DecodeFailure) Dump() (s string)

Dump implements Dumper.

func (*DecodeFailure) Error

func (d *DecodeFailure) Error() error

Error returns the error encountered during decoding.

func (*DecodeFailure) LayerContents

func (d *DecodeFailure) LayerContents() []byte

LayerContents implements Layer.

func (*DecodeFailure) LayerPayload

func (d *DecodeFailure) LayerPayload() []byte

LayerPayload implements Layer.

func (*DecodeFailure) LayerType

func (d *DecodeFailure) LayerType() gopacket.LayerType

LayerType returns LayerTypeDecodeFailure

func (*DecodeFailure) String

func (d *DecodeFailure) String() string

String implements fmt.Stringer.

type MyPacketBuilder

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

MyPacketBuilder is a PacketBuilder implementation that does eager decoding. Upon initial construction, it decodes all the layers it can from packet data.
