2017-03-12T05:37:28+00:00

commit 1c68bb0f62bf8de8bb30123ea840d5168f25abea upstream.

Running with KASAN and crypto tests currently gives

This always happens on the same IV which is less than 16 bytes.

Per Ard,

"CCM IVs are 16 bytes, but due to the way they are constructed
internally, the final couple of bytes of input IV are dont-cares.

Apparently, we do read all 16 bytes, which triggers the KASAN errors."

Fix this by padding the IV with null bytes to be at least 16 bytes.

crypto: keywrap - add testmgr support

2015-10-15T13:05:08+00:00

The testmanager code for symmetric ciphers is extended to allow
verification of the IV after a cipher operation.

In addition, test vectors for kw(aes) for encryption and decryption are
added.

crypto: testmgr - test IV value after a cipher operation

2015-10-15T13:05:01+00:00

The crypto drivers are supposed to update the IV passed to the crypto
request before calling the completion callback.
Test for the IV value before considering the test as successful.

crypto: akcipher - Changes to asymmetric key API

2015-10-14T14:23:16+00:00

Setkey function has been split into set_priv_key and set_pub_key.
Akcipher requests takes sgl for src and dst instead of void *.
Users of the API i.e. two existing RSA implementation and
test mgr code have been updated accordingly.

crypto: testmgr - Disable authenc test and convert test vectors

2015-08-04T12:45:30+00:00

This patch disables the authenc tests while the conversion to the
new IV calling convention takes place.  It also replaces the authenc
test vectors with ones that will work with the new IV convention.

crypto: testmgr - Add a longer ChaCha20 test vector

2015-07-17T13:20:26+00:00

The AVX2 variant of ChaCha20 is used only for messages with >= 512 bytes
length. With the existing test vectors, the implementation could not be
tested. Due that lack of such a long official test vector, this one is
self-generated using chacha20-generic.
