type IterateCallback ¶

type IterateCallback func(*L2ResponderKey, *L2ResponderStats)

IterateCallback 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 L2 responder map.

type L2ResponderKey ¶

type L2ResponderKey struct {
	IP      types.IPv4 `align:"ip"`
	IfIndex uint32     `align:"ifindex"`
}

L2ResponderKey implements the bpf.MapKey interface.

Must be in sync with struct l2_responder_v4_key in <bpf/lib/maps.h>

func (k *L2ResponderKey) String() string

type L2ResponderStats ¶

type L2ResponderStats struct {
	ResponsesSent uint64 `align:"responses_sent"`
}

L2ResponderStats implements the bpf.MapValue interface.

Must be in sync with struct l2_responder_v4_stats in <bpf/lib/maps.h>

func (s *L2ResponderStats) String() string

type Map ¶

type Map interface {
	Create(ip netip.Addr, ifIndex uint32) error
	Lookup(ip netip.Addr, ifIndex uint32) (*L2ResponderStats, error)
	Delete(ip netip.Addr, ifIndex uint32) error
	IterateWithCallback(cb IterateCallback) error
}

func NewFakeMap() Map

func NewMap(lifecycle cell.Lifecycle) (Map, error)
