crypto: caam - add support for acipher xts(aes)

2015-10-08T13:42:20+00:00

Add support for AES working in XEX-based Tweaked-codebook mode with
ciphertext Stealing (XTS)

sector index - HW limitation: CAAM device supports sector index of only
8 bytes to be used for sector index inside IV, instead of whole 16 bytes
received on request. This represents 2 ^ 64 = 16,777,216 Tera of possible
values for sector index.

crypto: caam - dma_map_sg can handle chained SG

2015-10-01T13:56:56+00:00

The caam driver use two dma_map_sg path according to SG are chained
or not.
Since dma_map_sg can handle both case, clean the code with all
references to sg chained.

Thus removing dma_map_sg_chained, dma_unmap_sg_chained
and __sg_count functions.

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.

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.

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.

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.
