Documentation

Overview

Package neighborsmap represents the map that stores IP to mac address mappings for NodePort clients. It is primarily managed from the datapath; Cilium side is used to create the map only. +groupName=maps

Functions

func InitMaps

func InitMaps(ipv4, ipv6 bool) error

InitMaps creates the nodeport neighbors maps in the kernel.

Types

type Key4

type Key4 struct {
	// contains filtered or unexported fields
}

Key4 is the IPv4 for the IP-to-MAC address mappings. +k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapKey

func (*Key4) DeepCopy

func (in *Key4) DeepCopy() *Key4

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Key4.

func (*Key4) DeepCopyInto

func (in *Key4) DeepCopyInto(out *Key4)

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

func (*Key4) DeepCopyMapKey

func (in *Key4) DeepCopyMapKey() bpf.MapKey

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

func (*Key4) GetKeyPtr

func (k *Key4) GetKeyPtr() unsafe.Pointer

GetKeyPtr returns the unsafe pointer to the BPF key

func (Key4) NewValue

func (k Key4) NewValue() bpf.MapValue

NewValue returns a new empty instance of the structure representing the BPF map value.

func (*Key4) String

func (k *Key4) String() string

String converts the key into a human readable string format.

type Key6

type Key6 struct {
	// contains filtered or unexported fields
}

Key6 is the IPv6 for the IP-to-MAC address mappings. +k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapKey

func (*Key6) DeepCopy

func (in *Key6) DeepCopy() *Key6

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Key6.

func (*Key6) DeepCopyInto
