This code/logic is spurious, because the majority of packets are translated by eBPF, so whether the daemon runs or not, usually just doesn't matter - bpf will handle them anyway. As such what we actually care about is that the daemon is terminated at the same time as the bpf map configuration is removed. This is done by jni native code stopClatdProcess() which is called from ClatCoordinator java code immediately after maybeStopBpf(). Additionally on ipv6 address change we don't even terminate the daemon - we simply stop the event loop, but still block in main() until we receive SIGTERM/SIGKILL. (This was done a while ago to fix a bunch of issues with daemon dieing and being killed racing with each other) Test: TreeHugger Signed-off-by: Maciej Żenczykowski <maze@google.com> Change-Id: I86d203a244838166ed1fbec1bc48a680e433f9fa
