  • Most generic crypto algorithms declare a driver name ending in
    "-generic". The rest don't declare a driver name and instead rely on
    the crypto API automagically appending "-generic" upon registration.

    Having multiple conventions is unnecessarily confusing and makes it
    harder to grep for all generic algorithms in the kernel source tree.
    But also, allowing NULL driver names is problematic because sometimes
    people fail to set it, e.g. the case fixed by commit 417980364300
    ("crypto: cavium/zip - fix collision with generic cra_driver_name").

    Of course, people can also incorrectly name their drivers "-generic".
    But that's much easier to notice / grep for.

    Therefore, let's make cra_driver_name mandatory. In preparation for
    this, this patch makes all generic algorithms set cra_driver_name.

  • 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.

  • Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH. But this
    is redundant with the C structure type ('struct shash_alg'), and
    crypto_register_shash() already sets the type flag automatically,
    clearing any type flag that was already there. Apparently the useless
    assignment has just been copy+pasted around.

    So, remove the useless assignment from all the shash algorithms.

    This patch shouldn't change any actual behavior.

  • ARRAY_SIZE is more concise to use when the size of an array is divided by
    the size of its type or the size of its first element.

    The semantic patch that makes this change is as follows:

    Thanks for the suggestion, the init() is replaced with

    _mod_init ()

    and fini () is replaced with _mod_fini.

  • Up until now algorithms have been happy to get a context pointer since
    they know everything that's in the tfm already (e.g., alignment, block
    size).

    However, once we have parameterised algorithms, such information will
    be specific to each tfm. So the algorithm API needs to be changed to
    pass the tfm structure instead of the context pointer.

    This patch is basically a text substitution. The only tricky bit is
    the assembly routines that need to get the context pointer offset
    through asm-offsets.h.

  • A lot of crypto code needs to read/write a 32-bit/64-bit words in a
    specific gender. Many of them open code them by reading/writing one
    byte at a time. This patch converts all the applicable usages over
    to use the standard byte order macros.

    This is based on a previous patch by Denis Vlasenko.

  • Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
