crypto: qce - use AES fallback for small requests

2020-02-13T09:05:27+00:00

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. Signed-off-by: Eneas U de Queiroz Signed-off-by: Herbert Xu

crypto: exynos-rng - Rename Exynos to lowercase

2020-01-09T03:30:58+00:00

Fix up inconsistent usage of upper and lowercase letters in "Exynos" name. "EXYNOS" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Herbert Xu

crypto: qce - allow building only hashes/ciphers

2019-12-27T10:18:04+00:00

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.

crypto: inside-secure - add unspecified HAS_IOMEM dependency

2019-12-20T06:58:34+00:00

Currently CONFIG_CRYPTO_DEV_SAFEXCEL=y implicitly depends on CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get the following build error: ld: drivers/crypto/inside-secure/safexcel.o: in function `safexcel_probe': drivers/crypto/inside-secure/safexcel.c:1692: undefined reference to `devm_platform_ioremap_resource' Fix the build error by adding the unspecified dependency.

crypto: bcm-spu - switch to skcipher API

2019-11-17T01:02:46+00:00

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. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu
