  • d6ebf5286   crypto: make all generic algorithms set cra_driver_name ... Browse Code »

    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.

  • 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.

  • 8d6053984   crypto: null - Remove VLA usage of skcipher ... Browse Code »

    In the quest to remove all stack VLA usage from the kernel[1], this
    replaces struct crypto_skcipher and SKCIPHER_REQUEST_ON_STACK() usage
    with struct crypto_sync_skcipher and SYNC_SKCIPHER_REQUEST_ON_STACK(),
    which uses a fixed stack size.

  • e50944e21   crypto: shash - remove useless setting of type flags ... Browse Code »

    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.

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

    _mod_init ()

    and fini () is replaced with _mod_fini.

  • 560c06ae1   [CRYPTO] api: Get rid of flags argument to setkey ... Browse Code »

    Now that the tfm is passed directly to setkey instead of the ctx, we no
    longer need to pass the &tfm->crt_flags pointer.

    This patch also gets rid of a few unnecessary checks on the key length
    for ciphers as the cipher layer guarantees that the key length is within
    the bounds specified by the algorithm.

    Rather than testing dia_setkey every time, this patch does it only once
    during crypto_alloc_tfm. The redundant check from crypto_digest_setkey
    is also removed.

  • 6c2bb98bc   [CRYPTO] all: Pass tfm instead of ctx to algorithms ... Browse Code »

    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.

    null_encrypt() needs to copy the data in case src and dst are disjunct,

    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!
