KEYS: Set the asymmetric-key type default search method
The keyring expansion patches introduces a new search method by which key_search() attempts to walk directly to the key that has exactly the same description as the requested one. However, this causes inexact matching of asymmetric keys to fail. The solution to this is to select iterative rather than direct search as the default search type for asymmetric keys. As an example, the kernel might have a key like this: Magrathea: Glacier signing key: 6a2a0f82bad7e396665f465e4e3e1f9bd24b1226 and: keyctl search <keyring-ID> asymmetric id:d24b1226 should find the key, despite that not being its exact description.
