Types

type MapSweeper

type MapSweeper struct {
	// contains filtered or unexported fields
}

MapSweeper is responsible for checking stale map paths on the filesystem and garbage collecting the endpoint if the corresponding endpoint no longer exists.

func NewMapSweeper

func NewMapSweeper(g endpointManager) *MapSweeper

NewMapSweeper creates an object that walks map paths and garbage-collects them.

func (*MapSweeper) CollectStaleMapGarbage

func (ms *MapSweeper) CollectStaleMapGarbage()

CollectStaleMapGarbage cleans up stale content in the BPF maps from the datapath.

func (*MapSweeper) RemoveDisabledMaps

func (ms *MapSweeper) RemoveDisabledMaps()

RemoveDisabledMaps removes BPF maps in the filesystem for features that have been disabled. The maps may still be in use in which case they will continue to live until the BPF program using them is being replaced.
