crypto: caam - Set last bit on src SG list

2015-06-19T06:16:32+00:00

The new aead_edesc_alloc left out the bit indicating the last
entry on the source SG list.  This patch fixes it.

crypto: caam - Reintroduce DESC_MAX_USED_BYTES

2015-06-19T06:16:31+00:00

I incorrectly removed DESC_MAX_USED_BYTES when enlarging the size
of the shared descriptor buffers, thus making it four times larger
than what is necessary.  This patch restores the division by four
calculation.

crypto: caam - Convert GCM to new AEAD interface

2015-06-17T07:35:08+00:00

This patch converts the caam GCM implementations to the new AEAD
interface.  This is compile-tested only.

Note that all IV generation for GCM algorithms have been removed.
The reason is that the current generation uses purely random IVs
which is not appropriate for counter-based algorithms where we
first and foremost require uniqueness.

Of course there is no reason why you couldn't implement seqiv or
seqniv within caam since all they do is xor the sequence number
with a salt, but since I can't test this on actual hardware I'll
leave it alone for now.

crypto: caam - Clamp AEAD SG list by input length

2015-06-09T14:25:58+00:00

Currently caam assumes that the SG list contains exactly the number
of bytes required.  This assumption is incorrect.

Up until now this has been harmless.  However with the new AEAD
interface this now breaks as the AD SG list contains more bytes
than just the AD.

This patch fixes this by always clamping the AD SG list by the
specified AD length.

crypto: caam - Use old_aead_alg

2015-05-22T03:25:53+00:00

This patch replaces references to aead_alg with old_aead_alg.

crypto: caam - Remove unnecessary reference to crt_aead

2015-05-13T02:31:35+00:00

crt_aead is an internal implementation detail and must not be
used outside of the crypto API itself.  This patch replaces the
unnecessary uses of crt_aead with crypto_aead_ivsize.

crypto: caam - Remove bogus references to crypto API internals

2015-04-23T06:18:08+00:00

The caam driver includes algorithm types that it doesn't even
use, such as struct rng_alg which has recently been moved to an
internal header file and consequently broke the build of caam.

This patch removes these bogus references.

crypto: caam - remove dead code

2015-01-26T00:34:23+00:00

- assoc_nents and src_nents are never zero when all_contig is false
- iv_contig is zero on the else branch

crypto: caam - add support for givencrypt cbc(aes) and rfc3686(ctr(aes))

2014-11-06T15:15:05+00:00

Add support for one-shot givencrypt algorithms.
Givencrypt algorithms will generate their IV and encrypt data
within the same shared job descriptors.
Current algorithms merged from ablkcipher to givencrypt are:
 - AES Cipher Block Chaining (CBC)
 - AES Counter Mode (CTR) compliant with RFC3686
