  • 7682cd97a   crypto: atmel-i2c - select CONFIG_BITREVERSE ... Browse Code »

    [ Upstream commit d33a23b0532d5d1b5b700e8641661261e7dbef61 ]

    The bitreverse helper is almost always built into the kernel,
    but in a rare randconfig build it is possible to hit a case
    in which it is a loadable module while the atmel-i2c driver
    is built-in:

    arm-linux-gnueabi-ld: drivers/crypto/atmel-i2c.o: in function `atmel_i2c_checksum':
    atmel-i2c.c:(.text+0xa0): undefined reference to `byte_rev_table'

    Add one more 'select' statement to prevent this.

    The Mediatek accelerator driver calls into a dynamically allocated

    There is no point in using the skcipher API for this, so use the AES
    library interface instead.

    Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

  • ce163ba0b   crypto: qce - use AES fallback for small requests ... Browse Code »

    Process small blocks using the fallback cipher, as a workaround for an
    observed failure (DMA-related, apparently) when computing the GCM ghash
    key. This brings a speed gain as well, since it avoids the latency of
    using the hardware engine to process small blocks.

    Using software for all 16-byte requests would be enough to make GCM
    work, but to increase performance, a larger threshold would be better.
    Measuring the performance of supported ciphers with openssl speed,
    software matches hardware at around 768-1024 bytes.

    Considering the 256-bit ciphers, software is 2-3 times faster than qce
    at 256-bytes, 30% faster at 512, and about even at 768-bytes. With
    128-bit keys, the break-even point would be around 1024-bytes.

    This adds the 'aes_sw_max_len' parameter, to set the largest request
    length processed by the software fallback. Its default is being set to
    512 bytes, a little lower than the break-even point, to balance the cost
    in CPU usage.

    Allow the user to choose whether to build support for all algorithms
    (default), hashes-only, or skciphers-only.

    The QCE engine does not appear to scale as well as the CPU to handle
    multiple crypto requests. While the ipq40xx chips have 4-core CPUs, the
    QCE handles only 2 requests in parallel.

    Ipsec throughput seems to improve when disabling either family of
    algorithms, sharing the load with the CPU. Enabling skciphers-only
    appears to work best.

    Commit 7a7ffe65c8c5 ("crypto: skcipher - Add top-level skcipher interface")
    dated 20 august 2015 introduced the new skcipher API which is supposed to
    replace both blkcipher and ablkcipher. While all consumers of the API have
    been converted long ago, some producers of the ablkcipher remain, forcing
    us to keep the ablkcipher support routines alive, along with the matching
    code to expose [a]blkciphers via the skcipher API.

    So switch this driver to the skcipher API, allowing us to finally drop the
    ablkcipher code in the near future.
