Functions

func SetNodeMap

func SetNodeMap(m *Map)

SetNodeMap sets the node map. Only used for testing.

Types

type Map

type Map struct {
	*ebpf.Map
}

func NewNodeMap

func NewNodeMap(mapName string) *Map

func NodeMap

func NodeMap() *Map

func (*Map) Delete

func (m *Map) Delete(ip net.IP) error

func (Map) IterateWithCallback

func (m Map) IterateWithCallback(cb NodeIterateCallback) error

IterateWithCallback iterates through all the keys/values of a node map, passing each key/value pair to the cb callback.

func (*Map) Update

func (m *Map) Update(ip net.IP, nodeID uint16) error

type NodeIterateCallback

type NodeIterateCallback func(*NodeKey, *NodeValue)

NodeIterateCallback represents the signature of the callback function expected by the IterateWithCallback method, which in turn is used to iterate all the keys/values of a node map.

type NodeKey

type NodeKey struct {
	Pad1   uint16 `align:"pad1"`
	Pad2   uint8  `align:"pad2"`
	Family uint8  `align:"family"`
	// represents both IPv6 and IPv4 (in the lowest four bytes)
	IP types.IPv6 `align:"$union0"`
}

func (*NodeKey) String

func (k *NodeKey) String() string

type NodeValue

type NodeValue struct {
	NodeID uint16
}
