Types

type EgressInfo4

type EgressInfo4 struct {
	EgressIP       types.IPv4 `align:"egress_ip"`
	TunnelEndpoint types.IPv4 `align:"tunnel_endpoint"`
}

EgressInfo4 implements the bpf.MapValue interface. It contains the information about egress gateway and egress IP address for masquerading. +k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapValue

func (*EgressInfo4) DeepCopy

func (in *EgressInfo4) DeepCopy() *EgressInfo4

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new EgressInfo4.

func (*EgressInfo4) DeepCopyInto

func (in *EgressInfo4) DeepCopyInto(out *EgressInfo4)

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

func (*EgressInfo4) DeepCopyMapValue

func (in *EgressInfo4) DeepCopyMapValue() bpf.MapValue

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

func (*EgressInfo4) GetValuePtr

func (v *EgressInfo4) GetValuePtr() unsafe.Pointer

GetValuePtr returns the unsafe pointer to the BPF value.

func (*EgressInfo4) String

func (v *EgressInfo4) String() string

String pretty print the egress information.

type Key4

type Key4 struct {
	// PrefixLen is full 32 bits of SourceIP + DestCIDR's mask bits
	PrefixLen uint32

	SourceIP types.IPv4
	DestCIDR types.IPv4
}

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

func NewKey

func NewKey(src, dst net.IP, mask net.IPMask) Key4

NewKey returns a new Key4 instance

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

func (*Key4) NewValue

func (k *Key4) NewValue() bpf.MapValue

func (*Key4) String

func (k *Key4) String() string
