The cca on the crypto adapter has a restriction in the size of the exponent if a key with a modulus bigger than 2048 bit is used. Thus in that case we have to avoid that the crypto device driver thinks the adapter is defect and sets it offline. Therfore a new member for the zcrypt_device struct called max_exp_bit_length is introduced. This will be set the first time the cca returns the error code function not implemented. If this is done with an adapter twice it will return -EINVAL. Signed-off-by: Felix Beck <felix.beck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> |
