This patch converts the padlock-sha implementation to shash. In doing so the existing mechanism of storing the data until final is no longer viable as we do not have a way of allocating data in crypto_shash_init and then reliably freeing it. This is just as well because a better way of handling the problem is to hash everything but the last chunk using normal sha code and then provide the intermediate result to the padlock device. This is good enough because the primary application of padlock-sha is IPsec and there the data is laid out in the form of an hmac header followed by the rest of the packet. In essence we can provide all the data to the padlock as the hmac header only needs to be hashed once. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This is the s390 hardware accelerated implementation of the
|
|
AES cipher algorithms (FIPS-197). AES uses the Rijndael
|
|
algorithm.
|
|
|
|
Rijndael appears to be consistently a very good performer in
|
|
both hardware and software across a wide range of computing
|
|
environments regardless of its use in feedback or non-feedback
|
|
modes. Its key setup time is excellent, and its key agility is
|
|
good. Rijndael's very low memory requirements make it very well
|
|
suited for restricted-space environments, in which it also
|
|
demonstrates excellent performance. Rijndael's operations are
|
|
among the easiest to defend against power and timing attacks.

On s390 the System z9-109 currently only supports the key size
|
|
of 128 bit.
