      crypto: chacha20-generic - refactor to allow varying number of rounds · 1ca1b917
      由 Eric Biggers 提交于 
      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.

      crypto: caam/jr - fix ablkcipher_edesc pointer arithmetic · 13cc6f48
      由 Horia Geantă 提交于 
      In some cases the zero-length hw_desc array at the end of
ablkcipher_edesc struct requires for 4B of tail padding.

Due to tail padding and the way pointers to S/G table and IV
are computed:
	edesc->sec4_sg = (void *)edesc + sizeof(struct ablkcipher_edesc) +
			 desc_bytes;
	iv = (u8 *)edesc->hw_desc + desc_bytes + sec4_sg_bytes;
first 4 bytes of IV are overwritten by S/G table.

Update computation of pointer to S/G table to rely on offset of hw_desc
member and not on sizeof() operator.

      crypto: caam/qi - fix compilation with DEBUG enabled · 972b812b
      由 Horia Geantă 提交于 
      caam/qi driver does not compile when DEBUG is enabled
(CRYPTO_DEV_FSL_CAAM_DEBUG=y):

drivers/crypto/caam/caamalg_qi.c: In function 'ablkcipher_done':
drivers/crypto/caam/caamalg_qi.c:794:2: error: implicit declaration of function 'dbg_dump_sg' [-Werror=implicit-function-declaration]
  dbg_dump_sg(KERN_ERR, "dst    @" __stringify(__LINE__)": ",

Since dbg_dump_sg() is shared between caam/jr and caam/qi, move it
in a shared location and export it.

At the same time:
-reduce ifdeferry by providing a no-op implementation for !DEBUG case
-rename it to caam_dump_sg() to be consistent in terms of
exported symbols namespace (caam_*)

      crypto: caam - properly set IV after {en,de}crypt · 854b06f7
      由 David Gstir 提交于 
      Certain cipher modes like CTS expect the IV (req->info) of
ablkcipher_request (or equivalently req->iv of skcipher_request) to
contain the last ciphertext block when the {en,de}crypt operation is done.
This is currently not the case for the CAAM driver which in turn breaks
e.g. cts(cbc(aes)) when the CAAM driver is enabled.

This patch fixes the CAAM driver to properly set the IV after the
{en,de}crypt operation of ablkcipher finishes.

This issue was revealed by the changes in the SW CTS mode in commit
0605c41c ("crypto: cts - Convert to skcipher")

      crypto: caam - pass key buffers with typesafe pointers · 9c0bc511
      由 Arnd Bergmann 提交于 
      The 'key' field is defined as a 'u64' and used for two different
pieces of information: either to store a pointer or a dma_addr_t.
The former leads to a build error on 32-bit machines:

drivers/crypto/caam/caamalg_desc.c: In function 'cnstr_shdsc_aead_null_encap':
drivers/crypto/caam/caamalg_desc.c:67:27: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
drivers/crypto/caam/caamalg_desc.c: In function 'cnstr_shdsc_aead_null_decap':
drivers/crypto/caam/caamalg_desc.c:143:27: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

Using a union to provide correct types gets rid of the warnings
and as well as a couple of redundant casts.
