Functions

func SetTunnelMap added in v0.15.7

func SetTunnelMap(m *Map)

SetTunnelMap sets the tunnel map. Only used for testing.

Types

type Map added in v0.15.7

type Map struct {

}

Map implements tunnel connectivity configuration in the BPF datapath.

func NewTunnelMap added in v0.15.7

func NewTunnelMap(mapName string) *Map

NewTunnelMap returns a new tunnel map.

func TunnelMap added in v0.15.7

func TunnelMap() *Map

func (*Map) DeleteTunnelEndpoint added in v0.15.7

func (m *Map) DeleteTunnelEndpoint(prefix net.IP) error

DeleteTunnelEndpoint removes a prefix => tunnel-endpoint mapping

func (*Map) GetTunnelEndpoint added in v0.15.7

func (m *Map) GetTunnelEndpoint(prefix net.IP) (net.IP, error)

GetTunnelEndpoint retrieves a prefix => tunnel-endpoint mapping

func (*Map) SetTunnelEndpoint added in v0.15.7

func (m *Map) SetTunnelEndpoint(encryptKey uint8, prefix, endpoint net.IP) error
