KEYS: Add placeholder for KDF usage with DH
The values computed during Diffie-Hellman key exchange are often used in combination with key derivation functions to create cryptographic keys. Add a placeholder for a later implementation to configure a key derivation function that will transform the Diffie-Hellman result returned by the KEYCTL_DH_COMPUTE command. [This patch was stripped down from a patch produced by Mat Martineau that had a bug in the compat code - so for the moment Stephan's patch simply requires that the placeholder argument must be NULL] Original-signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: James Morris <james.l.morris@oracle.com>
