  • b3c16bfc6   crypto: skcipher - Add skcipher_ialg_simple helper ... Browse Code »

    This patch introduces the skcipher_ialg_simple helper which fetches
    the crypto_alg structure from a simple skcipher instance's spawn.

    This allows us to remove the third argument from the function
    skcipher_alloc_instance_simple.

    In doing so the reference count to the algorithm is now maintained
    by the Crypto API and the caller no longer needs to drop the alg
    refcount.

  • c4741b230   crypto: run initcalls for generic implementations earlier ... Browse Code »

    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.

  • 4943ba16b   crypto: include crypto- module prefix in template ... Browse Code »

    This adds the module loading prefix "crypto-" to the template lookup
    as well.

    For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly
    includes the "crypto-" prefix at every level, correctly rejecting "vfat":

    net-pf-38
    algif-hash
    crypto-vfat(blowfish)
    crypto-vfat(blowfish)-all
    crypto-vfat

  • ebc610e5b   [CRYPTO] templates: Pass type/mask when creating instances ... Browse Code »

    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.

  • db131ef90   [CRYPTO] cipher: Added block ciphers for CBC/ECB ... Browse Code »

    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.
