[CRYPTO] api: Split out low-level API The crypto API is made up of the part facing users such as IPsec and the low-level part which is used by cryptographic entities such as algorithms. This patch splits out the latter so that the two APIs are more clearly delineated. As a bonus the low-level API can now be modularised if all algorithms are built as modules.

[CRYPTO] templates: Pass type/mask when creating instances This patch passes the type/mask along when constructing instances of templates. This is in preparation for templates that may support multiple types of instances depending on what is requested. For example, the planned software async crypto driver will use this construct. For the moment this allows us to check whether the instance constructed is of the correct type and avoid returning success if the type does not match.

[CRYPTO] api: Added crypto_type support This patch adds the crypto_type structure which will be used for all new crypto algorithm types, beginning with block ciphers. The primary purpose of this abstraction is to allow different crypto_type objects for crypto algorithms of the same type, in particular, there will be a different crypto_type objects for asynchronous algorithms.

[CRYPTO] api: Do not remove users unless new algorithm matches As it is whenever a new algorithm with the same name is registered users of the old algorithm will be removed so that they can take advantage of the new algorithm. This presents a problem when the new algorithm is not equivalent to the old algorithm. In particular, the new algorithm might only function on top of the existing one. Hence we should not remove users unless they can make use of the new algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] scatterwalk: Prepare for block ciphers This patch prepares the scatterwalk code for use by the new block cipher type. Firstly it halves the size of scatter_walk on 32-bit platforms. This is important as we allocate at least two of these objects on the stack for each block cipher operation. It also exports the symbols since the block cipher code can be built as a module. Finally there is a hack in scatterwalk_unmap that relies on progress being made. Unfortunately, for hardware crypto we can't guarantee progress to be made since the hardware can fail. So this also gets rid of the hack by not advancing the address returned by scatterwalk_map. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] cipher: Added block cipher type This patch adds the new type of block ciphers. Unlike current cipher algorithms which operate on a single block at a time, block ciphers operate on an arbitrarily long linear area of data. As it is block-based, it will skip any data remaining at the end which cannot form a block. The block cipher has one major difference when compared to the existing block cipher implementation. The sg walking is now performed by the algorithm rather than the cipher mid-layer. This is needed for drivers that directly support sg lists. It also improves performance for all algorithms as it reduces the total number of indirect calls by one. In future the existing cipher algorithm will be converted to only have a single-block interface. This will be done after all existing users have switched over to the new block cipher type.

[CRYPTO] digest: Added user API for new hash type The existing digest user interface is inadequate for support asynchronous operations. For one it doesn't return a value to indicate success or failure, nor does it take a per-operation descriptor which is essential for the issuing of requests while other requests are still outstanding. This patch is the first in a series of steps to remodel the interface for asynchronous operations. For the ease of transition the new interface will be known as "hash" while the old one will remain as "digest". This patch also changes sg_next to allow chaining.
