crypto: hash - Add real ahash walk interface

2014-05-21T12:56:12Z

Although the existing hash walk interface has already been used by a number of ahash crypto drivers, it turns out that none of them were really asynchronous. They were all essentially polling for completion. That's why nobody has noticed until now that the walk interface couldn't work with a real asynchronous driver since the memory is mapped using kmap_atomic. As we now have a use-case for a real ahash implementation on x86, this patch creates a minimal ahash walk interface. Basically it just calls kmap instead of kmap_atomic and does away with the crypto_yield call. Real ahash crypto drivers don't need to yield since by definition they won't be hogging the CPU.

crypto: allow blkcipher walks over AEAD data

2014-03-10T12:17:11Z

This adds the function blkcipher_aead_walk_virt_block, which allows the caller to use the blkcipher walk API to handle the input and output scatterlists. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: remove direct blkcipher_walk dependency on transform

2014-03-10T12:17:10Z

In order to allow other uses of the blkcipher walk API than the blkcipher algos themselves, this patch copies some of the transform data members to the walk struct so the transform is only accessed at walk init time. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: scatterwalk - Use sg_chain_ptr on chain entries

2013-12-09T11:58:52Z

Now that scatterwalk_sg_chain sets the chain pointer bit the sg_page call in scatterwalk_sg_next hits a BUG_ON when CONFIG_DEBUG_SG is enabled. Use sg_chain_ptr instead of sg_page on a chain entry. Cc: stable@vger.kernel.org Signed-off-by: Tom Lendacky Signed-off-by: Herbert Xu

crypto: scatterwalk - Set the chain pointer indication bit

2013-11-28T14:16:24Z

The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain function to chain two scatterlists, but the chain pointer indication bit is not set. When the resulting scatterlist is used, for example, by sg_nents to count the number of scatterlist entries, a segfault occurs because sg_nents does not follow the chain pointer to the chained scatterlist. Update scatterwalk_sg_chain to set the chain pointer indication bit as is done by the sg_chain function. Cc: stable@vger.kernel.org Signed-off-by: Tom Lendacky Signed-off-by: Herbert Xu
