const (
	// MapName name of map used to pin map for datapath
	MapName = "cilium_runtime_config"
)

Variables ¶

View Source

var Cell = cell.Module(
	"config-map",
	"eBPF map config contains runtime configuration state for the Cilium datapath",

	cell.Provide(provide),
)

Cell initializes and manages the config map.

Functions ¶

This section is empty.

Types ¶

type Index ¶

type Index uint32

Index is the index to the runtime config array.

const (
	UTimeOffset Index = iota
	AgentLiveness
)

All supported indices in one place. Must be in sync with RUNTIME_CONFIG_ enum in bpf/lib/common.h

func (*Index) New ¶

func (k *Index) New() bpf.MapKey

func (Index) String ¶

func (r Index) String() string

String pretty print the Index

type Map ¶

type Map interface {
	// Update writes the given uint64 value to the bpf map at the given index.
	Update(index Index, val uint64) error

	Get(index Index) (uint64, error)
}

Map provides access to the eBPF map configmap.

func LoadMap ¶

func LoadMap(logger *slog.Logger) (Map, error)

LoadMap loads the pre-initialized config map for access. This should only be used from components which aren't capable of using hive - mainly the Cilium CLI. It needs to initialized beforehand via the Cilium Agent.

type Value ¶

type Value uint64

Value is the generic datapath runtime config value.

func (*Value) New ¶

func (v *Value) New() bpf.MapValue

func (*Value) String ¶

func (v *Value) String() string

String pretty print the config Value.
