crypto: caam - add missing put_device() call

2019-03-07T08:24:52+00:00

The of_find_device_by_node() takes a reference to the underlying device
structure, we should release that reference.

crypto: caam - use mapped_{src,dst}_nents for job descriptor

2019-02-15T05:21:55+00:00

The mapped_{src,dst}_nents _returned_ from the dma_map_sg call (which
could be less than src/dst_nents) have to be used to generate the aead,
skcipher job descriptors.

crypto: caam - fixed handling of sg list

2019-02-08T07:30:08+00:00

when the source sg contains more than 1 fragment and
destination sg contains 1 fragment, the caam driver
mishandle the buffers to be sent to caam.

crypto: caam - handle zero-length AEAD output

2019-02-01T06:42:03+00:00

Recent AEAD changes in testmgr framework introduced by commit
a0d608ee5ebf ("crypto: testmgr - unify the AEAD encryption and decryption test vectors")
uncovered an error in the CAAM drivers, since they don't correctly
handle the case when AEAD output length is zero.

Add checks to avoid feeding zero-length req->dst to DMA API.

crypto: chacha20-generic - refactor to allow varying number of rounds

2018-11-20T06:26:55+00:00

In preparation for adding XChaCha12 support, rename/refactor
chacha20-generic to support different numbers of rounds.  The
justification for needing XChaCha12 support is explained in more detail
in the patch "crypto: chacha - add XChaCha12 support".

The only difference between ChaCha{8,12,20} are the number of rounds
itself; all other parts of the algorithm are the same.  Therefore,
remove the "20" from all definitions, structures, functions, files, etc.
that will be shared by all ChaCha versions.

Also make ->setkey() store the round count in the chacha_ctx (previously
chacha20_ctx).  The generic code then passes the round count through to
chacha_block().  There will be a ->setkey() function for each explicitly
allowed round count; the encrypt/decrypt functions will be the same.  I
decided not to do it the opposite way (same ->setkey() function for all
round counts, with different encrypt/decrypt functions) because that
would have required more boilerplate code in architecture-specific
implementations of ChaCha and XChaCha.
