I'm not seeing that behavior - each xsk holds it's own reference to xsks_maps, so when the map descriptor is closed, it doesn't necessarily delete the map. There's no refcount on the bpf program though; so the socket should not be trying to remove the program - that should be done by the application. -- Jonathan
