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

	// MaxEntries represents the maximum number of config entries.
	// Initially defined as 256, so that downgrade from a future version having more than one
	// entry works without necessarily resizing the map. Entries not known by the datapath
	// version are simply ignored.
	MaxEntries = 256

Variables

var Cell = cell.Module(

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.
