[CRYPTO] cipher: Added block ciphers for CBC/ECB This patch adds two block cipher algorithms, CBC and ECB. These are implemented as templates on top of existing single-block cipher algorithms. They invoke the single-block cipher through the new encrypt_one/decrypt_one interface. This also optimises the in-place encryption and decryption to remove the cost of an IV copy each round.

crypto: remove cipher routines from public crypto API The cipher routines in the crypto API are mostly intended for templates implementing skcipher modes generically in software, and shouldn't be used outside of the crypto subsystem. So move the prototypes and all related definitions to a new header file under include/crypto/internal. Also, let's use the new module namespace feature to move the symbol exports into a new namespace CRYPTO_INTERNAL.

[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: run initcalls for generic implementations earlier Use subsys_initcall for registration of all templates and generic algorithm implementations, rather than module_init. Then change cryptomgr to use arch_initcall, to place it before the subsys_initcalls. This is needed so that when both a generic and optimized implementation of an algorithm are built into the kernel (not loadable modules), the generic implementation is registered before the optimized one. Otherwise, the self-tests for the optimized implementation are unable to allocate the generic implementation for the new comparison fuzz tests. Note that on arm, a side effect of this change is that self-tests for generic implementations may run before the unaligned access handler has been installed. So, unaligned accesses will crash the kernel. This is arguably a good thing as it makes it easier to detect that type of bug.
