The tests in pasta/tcp and pasta/udp for inbound transfers have the server listening within the namespace explicitly bound to 127.0.0.1 or ::1. This only works because of the behaviour of inbound splice connections, which always appear with both source and destination addresses as loopback in the namespace. That's not an inherent property for "spliced" connections and arguably an undesirable one. Also update the test names to make it clearer that these tests are expecting to exercise the "splice" path. Interestingly this was already correct for the equivalent passt_in_ns/*, although we also update the test names for clarity there. Note that there are similar issues in some of the podman tests, addressed in https://github.com/containers/podman/pull/24064 Signed-off-by: David Gibson <david(a)gibson.dropbear.id.au> ---
