The c/storage SetNames API is depracated because it is not race free to first get the list of names and then append our new name then write the full list back. Instead a better Add/RemovesNames API has been added. Tag and Untag should use these to prevent race conditions that can be easily reproduce using podman tag in parallel. Tests have been added to ensure it is working correctly. Fixes containers/podman#17515 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
