Types ¶
type EndpointMapManager ¶ added in v1.19.0
type EndpointMapManager struct {
endpointmanager.EndpointManager
// contains filtered or unexported fields
}
EndpointMapManager is a wrapper around an endpointmanager as well as the filesystem for removing maps related to endpoints from the filesystem.
func (*EndpointMapManager) ListMapsDir ¶ added in v1.19.0
func (e *EndpointMapManager) ListMapsDir(path string) []string
ListMapsDir gives names of files (or subdirectories) found in the specified path.
func (*EndpointMapManager) RemoveDatapathMapping ¶ added in v1.19.0
func (e *EndpointMapManager) RemoveDatapathMapping(endpointID uint16) error
RemoveDatapathMapping unlinks the endpointID from the global policy map, preventing packets that arrive on this node from being forwarded to the endpoint that used to exist with the specified ID.
func (*EndpointMapManager) RemoveMapPath ¶ added in v1.19.0
func (e *EndpointMapManager) RemoveMapPath(path string)
RemoveMapPath removes the specified path from the filesystem.
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 (*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.
type PrefixedMap ¶ added in v1.17.7
PrefixedMap describes a pattern for filtering map files. It specifies which files to match via Prefix and which to exclude via Excludes.
