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, nodeID uint16, 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 TunnelIP

type TunnelIP struct {
	// represents both IPv6 and IPv4 (in the lowest four bytes)
	IP     types.IPv6 `align:"$union0"`
	Family uint8      `align:"family"`
}

+k8s:deepcopy-gen=true

func (*TunnelIP) DeepCopy

func (in *TunnelIP) DeepCopy() *TunnelIP

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

func (*TunnelIP) DeepCopyInto

func (in *TunnelIP) DeepCopyInto(out *TunnelIP)

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

type TunnelKey

type TunnelKey struct {
	TunnelIP
	ClusterID uint8  `align:"cluster_id"`
	Pad       uint16 `align:"pad"`
}

+k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapKey

func (*TunnelKey) DeepCopy

func (in *TunnelKey) DeepCopy() *TunnelKey

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

func (*TunnelKey) DeepCopyInto

func (in *TunnelKey) DeepCopyInto(out *TunnelKey)

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

func (*TunnelKey) DeepCopyMapKey

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

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

func (*TunnelKey) GetKeyPtr

func (k *TunnelKey) GetKeyPtr() unsafe.Pointer

GetKeyPtr returns the unsafe pointer to the BPF key

func (TunnelKey) NewValue

func (v TunnelKey) NewValue() bpf.MapValue

func (TunnelKey) String

func (k TunnelKey) String() string

String provides a string representation of the TunnelKey.
