Subject: [GIT PULL] security: keys updates for v4.20
Please pull. Note these patches have been in next and my tree under a
different branch for some weeks.
>From David: "Provide five new operations in the key_type struct that can
be used to provide access to asymmetric key operations. These will be
implemented for the asymmetric key type in a later patch and may refer to
a key retained in RAM by the kernel or a key retained in crypto hardware.
int (*asym_query)(const struct kernel_pkey_params *params,
struct kernel_pkey_query *info);
int (*asym_eds_op)(struct kernel_pkey_params *params,
const void *in, void *out);
int (*asym_verify_signature)(struct kernel_pkey_params *params,
const void *in, const void *in2);
Since encrypt, decrypt and sign are identical in their interfaces, they're
rolled together in the asym_eds_op() operation and there's an operation ID
in the params argument to distinguish them.
Verify is different in that we supply the data and the signature instead
and get an error value (or 0) as the only result on the expectation that
this may well be how a hardware crypto device may work."
