This test reproduces a UDP socket leak across sockmap lookup-bind-release,
but there is no Fixes: tag.
The sibling fix commit a2510dc351c5 ("bpf, sockmap: Don't leak UDP socks on
lookup-bind-release") carries a Fixes: tag pointing at the commit that lifted
the socket-state restriction allowing unbound UDP sockets into sockmap.
Should this test carry the same tag so it stays backportable alongside the
fix?
Fixes: 0c48eefae712 ("sock_map: Lift socket state restriction for datagram
sockets")
