  • 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.

  • 2062c5b6d   crypto: 842 - change 842 alg to use software ... Browse Code »

    Change the crypto 842 compression alg to use the software 842 compression
    and decompression library. Add the crypto driver_name as "842-generic".
    Remove the fallback to LZO compression.

    Previously, this crypto compression alg attemped 842 compression using
    PowerPC hardware, and fell back to LZO compression and decompression if
    the 842 PowerPC hardware was unavailable or failed. This should not
    fall back to any other compression method, however; users of this crypto
    compression alg can fallback if desired, and transparent fallback tricks
    callers into thinking they are getting 842 compression when they actually
    get LZO compression - the failure of the 842 hardware should not be
    transparent to the caller.

    The crypto compression alg for a hardware device also should not be located
    in crypto/ so this is now a software-only implementation that uses the 842
    software compression/decompression library.

  • 35a1fc187   powerpc/crypto: add 842 crypto driver ... Browse Code »

    This patch add the 842 cryptographic API driver that
    submits compression requests to the 842 hardware compression
    accelerator driver (nx-compress).

    If the hardware accelerator goes offline for any reason
    (dynamic disable, migration, etc...), this driver will use LZO
    as a software failover for all future compression requests.
    For decompression requests, the 842 hardware driver contains
    a software implementation of the 842 decompressor to support
    the decompression of data that was compressed before the accelerator
    went offline.
