Types

type TSOffset

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

TSOffset is an offset applied to the value of the TSVal field in the TCP Timestamp option.

func NewTSOffset

func NewTSOffset(milliseconds uint32) TSOffset

NewTSOffset creates a new TSOffset from milliseconds.

func (TSOffset) Elapsed

func (offset TSOffset) Elapsed(now tcpip.MonotonicTime, tsEcr uint32) time.Duration

Elapsed calculates the elapsed time given now and the echoed back timestamp.

func (*TSOffset) StateFields

func (offset *TSOffset) StateFields() []string

func (*TSOffset) StateLoad

func (offset *TSOffset) StateLoad(ctx context.Context, stateSourceObject state.Source)

+checklocksignore

func (*TSOffset) StateSave

func (offset *TSOffset) StateSave(stateSinkObject state.Sink)

+checklocksignore

func (*TSOffset) StateTypeName

func (offset *TSOffset) StateTypeName() string

func (TSOffset) TSVal

func (offset TSOffset) TSVal(now tcpip.MonotonicTime) uint32

TSVal applies the offset to now and returns the timestamp in milliseconds.
