crypto: caam - Use the preferred style for memory allocations

2015-08-24T14:07:42+00:00

"The preferred form for passing a size of a struct is the following: p = kmalloc(sizeof(*p), ...); .... The preferred form for allocating a zeroed array is the following: p = kcalloc(n, sizeof(...), ...); " ,so do as suggested. Signed-off-by: Fabio Estevam Reviewed-by: Horia Geant?

crypto: aead - Remove CRYPTO_ALG_AEAD_NEW flag

2015-08-17T08:53:53+00:00

This patch removes the CRYPTO_ALG_AEAD_NEW flag now that everyone has been converted. Signed-off-by: Herbert Xu

crypto: caam - Detect hardware features during algorithm registration

2015-08-10T15:19:04+00:00

Register only algorithms supported by CAAM hardware, using the CHA version and instantiation registers to identify hardware capabilities. Signed-off-by: Victoria Milhoan Tested-by: Horia Geantă Signed-off-by: Herbert Xu

crypto: caam - Change kmalloc to kzalloc to avoid residual data

2015-08-10T15:18:58+00:00

Since fields must be ORed in to operate correctly using any order of operations, changed allocations of the combination of extended descriptor structs + hardware scatterlists to use kzalloc() instead of kmalloc(), so as to ensure that residue data would not be ORed in with the correct data.

crypto: caam - Convert authenc to new AEAD interface

2015-08-04T12:45:31+00:00

This patch converts the authenc implementations in caam to the new AEAD interface. The biggest change is that seqiv no longer generates a random IV. Instead the IPsec sequence number is used as the IV. Signed-off-by: Herbert Xu

crypto: caam - fix rfc4106 encap shared descriptor

2015-07-31T07:17:33+00:00

The encap shared descriptor was changed to use the new IV convention. In the process some commands were shifted, making the output length zero, caam effectively writing garbage in dst. While here, update the decap descriptor to execute the "write" commands before the "read"s (as it previously was). This makes sure the input fifo is drained before becoming full.

crypto: caam - Use new IV convention

2015-07-14T06:56:47+00:00

This patch converts rfc4106 to the new calling convention where the IV is now part of the AD and needs to be skipped. Signed-off-by: Herbert Xu

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. Signed-off-by: Herbert Xu

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. Signed-off-by: Herbert Xu

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.
