Functions

func NtohsU16

func NtohsU16(n uint16) uint16

NtohsU16 converts an unsigned int16 from network order to host order

Types

type Conntracker

type Conntracker interface {
	GetTranslationForConn(ip util.Address, port uint16, transport process.ConnectionType) *IPTranslation
	ClearShortLived()
	GetStats() map[string]int64
	Close()
}

Conntracker is a wrapper around go-conntracker that keeps a record of all connections in user space

func NewConntracker

func NewConntracker(procRoot string, deleteBufferSize, maxStateSize int) (Conntracker, error)

NewConntracker creates a new conntracker with a short term buffer capped at the given size

func NewNoOpConntracker

func NewNoOpConntracker() Conntracker

NewNoOpConntracker creates a conntracker which always returns empty information

type IPTranslation

type IPTranslation struct {
	ReplSrcIP   util.Address
	ReplDstIP   util.Address
	ReplSrcPort uint16
	ReplDstPort uint16
}

IPTranslation can be associated with a connection to show show the connection is NAT'd
