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.

func (*MyPacketBuilder) AddLayer ¶

func (p *MyPacketBuilder) AddLayer(l gopacket.Layer)

func (*MyPacketBuilder) ApplicationLayer ¶

func (p *MyPacketBuilder) ApplicationLayer() gopacket.ApplicationLayer

func (*MyPacketBuilder) Data ¶

func (p *MyPacketBuilder) Data() []byte

func (*MyPacketBuilder) DecodeOptions ¶

func (p *MyPacketBuilder) DecodeOptions() *gopacket.DecodeOptions

func (*MyPacketBuilder) DumpPacketData ¶

func (p *MyPacketBuilder) DumpPacketData()

func (*MyPacketBuilder) ErrorLayer ¶

func (p *MyPacketBuilder) ErrorLayer() gopacket.ErrorLayer

func (*MyPacketBuilder) Layer ¶

func (*MyPacketBuilder) Layers ¶

func (p *MyPacketBuilder) Layers() []gopacket.Layer

func (*MyPacketBuilder) LinkLayer ¶

func (p *MyPacketBuilder) LinkLayer() gopacket.LinkLayer

func (*MyPacketBuilder) Metadata ¶

func (p *MyPacketBuilder) Metadata() *gopacket.PacketMetadata

func (*MyPacketBuilder) NetworkLayer ¶

func (p *MyPacketBuilder) NetworkLayer() gopacket.NetworkLayer

func (*MyPacketBuilder) NextDecoder ¶

func (p *MyPacketBuilder) NextDecoder(next gopacket.Decoder) error

func (*MyPacketBuilder) SetApplicationLayer ¶

func (p *MyPacketBuilder) SetApplicationLayer(l gopacket.ApplicationLayer)

func (*MyPacketBuilder) SetErrorLayer ¶

func (p *MyPacketBuilder) SetErrorLayer(l gopacket.ErrorLayer)

func (*MyPacketBuilder) SetLinkLayer ¶

func (p *MyPacketBuilder) SetLinkLayer(l gopacket.LinkLayer)

func (*MyPacketBuilder) SetNetworkLayer ¶

func (p *MyPacketBuilder) SetNetworkLayer(l gopacket.NetworkLayer)

func (*MyPacketBuilder) SetTransportLayer ¶

func (p *MyPacketBuilder) SetTransportLayer(l gopacket.TransportLayer)

func (*MyPacketBuilder) SetTruncated ¶

func (p *MyPacketBuilder) SetTruncated()

func (*MyPacketBuilder) TransportLayer ¶

func (p *MyPacketBuilder) TransportLayer() gopacket.TransportLayer

type ZeroCopyPacketSource ¶

type ZeroCopyPacketSource struct {
	gopacket.DecodeOptions
	// contains filtered or unexported fields
}

func NewZeroCopyPacketSource ¶

func NewZeroCopyPacketSource(source gopacket.PacketDataSource, decoder gopacket.Decoder) *ZeroCopyPacketSource

func (*ZeroCopyPacketSource) NextPacket ¶
