crypto: sa2ul - Select CRYPTO_AUTHENC

2020-10-29T09:11:07+00:00

[ Upstream commit 61f033ba18c37e6b9ddfc4ee6dffe049d981fe7e ] The sa2ul driver uses crypto_authenc_extractkeys and therefore must select CRYPTO_AUTHENC.

crypto: sa2ul - add Kconfig selects to fix build error

2020-08-21T04:43:51+00:00

sa2ul.c uses sha{1,256,512}_zero_message_hash, so select the Kconfig symbols that provide those, like other crypto drivers do. Fixes this build error: ld: drivers/crypto/sa2ul.o: in function `sa_sha_digest': sa2ul.c:(.text+0x2b25): undefined reference to `sha512_zero_message_hash' Fixes: 7694b6ca649f ("crypto: sa2ul - Add crypto driver") Signed-off-by: Randy Dunlap Reported-by: Randy Dunlap # 2020-07-29 Cc: Herbert Xu Cc: "David S.

Adds a basic crypto driver and currently supports AES/3DES in cbc mode for both encryption and decryption. Signed-off-by: Keerthy [t-kristo@ti.com: major re-work to fix various bugs in the driver and to cleanup the code] Signed-off-by: Tero Kristo Signed-off-by: Herbert Xu

crypto: mediatek - use AES library for GCM key derivation

2020-07-16T11:49:04+00:00

The Mediatek accelerator driver calls into a dynamically allocated skcipher of the ctr(aes) variety to perform GCM key derivation, which involves AES encryption of a single block consisting of NUL bytes. There is no point in using the skcipher API for this, so use the AES library interface instead. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: qce - support zero length test vectors

2020-07-03T04:18:34+00:00

crypto test module passes zero length vectors as test input to sha-1 and sha-256. To provide correct output for these vectors, hash zero support has been added as in other crypto drivers. Signed-off-by: Sivaprakash Murugesan Signed-off-by: Herbert Xu

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

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/' Signed-off-by: Masahiro Yamada

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
