Types

type Map

type Map struct {
	*bpf.Map
}

Map implements tunnel connectivity configuration in the BPF datapath.

func NewTunnelMap

func NewTunnelMap(name string) *Map

NewTunnelMap returns a new tunnel map with the specified name.

func (*Map) DeleteTunnelEndpoint

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

DeleteTunnelEndpoint removes a prefix => tunnel-endpoint mapping

func (*Map) GetTunnelEndpoint

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

GetTunnelEndpoint removes a prefix => tunnel-endpoint mapping

func (*Map) SetTunnelEndpoint

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

SetTunnelEndpoint adds/replaces a prefix => tunnel-endpoint mapping

func (*Map) SilentDeleteTunnelEndpoint

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

SilentDeleteTunnelEndpoint removes a prefix => tunnel-endpoint mapping. If the prefix is not found no error is returned.

type TunnelEndpoint

type TunnelEndpoint struct {
	bpf.EndpointKey
}

func (*TunnelEndpoint) DeepCopy

func (in *TunnelEndpoint) DeepCopy() *TunnelEndpoint

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new TunnelEndpoint.

func (*TunnelEndpoint) DeepCopyInto

func (in *TunnelEndpoint) DeepCopyInto(out *TunnelEndpoint)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*TunnelEndpoint) DeepCopyMapKey

func (in *TunnelEndpoint) DeepCopyMapKey() bpf.MapKey

DeepCopyMapKey is an autogenerated deepcopy function, copying the receiver, creating a new bpf.MapKey.

func (*TunnelEndpoint) DeepCopyMapValue

func (in *TunnelEndpoint) DeepCopyMapValue() bpf.MapValue

DeepCopyMapValue is an autogenerated deepcopy function, copying the receiver, creating a new bpf.MapValue.

func (TunnelEndpoint) NewValue

func (v TunnelEndpoint) NewValue() bpf.MapValue
