This can be observed e.g. with\nstrace (edited for clarity):\n\n    # ip nexthop add id 1 dev lo\n    # ip nexthop add id 101 group 1\n    # strace -e recvmsg ip nexthop get id 101\n    ...\n    recvmsg(...

But as they are, they\nleak kernel memory, and the fact they are not just zero complicates repurposing\nof the fields for new ends.
