crypto: ccree,hisilicon - Fix dependencies to correct algorithm

2023-01-07T10:15:56+00:00

commit 2ae6feb1a1f6678fe11864f1b6920ed10b09ad6a upstream. Commit d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") moves the SM3 and SM4 stand-alone library and the algorithm implementation for the Crypto API into the same directory, and the corresponding relationship of Kconfig is modified, CONFIG_CRYPTO_SM3/4 corresponds to the stand-alone library of SM3/4, and CONFIG_CRYPTO_SM3/4_GENERIC corresponds to the algorithm implementation for the Crypto API. Therefore, it is necessary for this module to depend on the correct algorithm. Fixes: d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") Cc: Jason A.

crypto: rockchip - rework by using crypto_engine

2022-12-31T12:26:17+00:00

[ Upstream commit 57d67c6e8219b2a034c16d6149e30fb40fd39935 ] Instead of doing manual queue management, let's use the crypto/engine for that. In the same time, rework the requests handling to be easier to understand (and fix all bugs related to them).

crypto: rockchip - add fallback for cipher

[ Upstream commit 68ef8af09a1a912a5ed2cfaa4cca7606f52cef90 ] The hardware does not handle 0 size length request, let's add a fallback. Furthermore fallback will be used for all unaligned case the hardware cannot handle.

crypto: s390 - do not depend on CRYPTO_HW for SIMD implementations

2022-07-07T03:04:06+00:00

Various accelerated software implementation Kconfig values for S390 were mistakenly placed into drivers/crypto/Kconfig, even though they're mainly just SIMD code and live in arch/s390/crypto/ like usual. This gives them the very unusual dependency on CRYPTO_HW, which leads to problems elsewhere. This patch fixes the issue by moving the Kconfig values for non-hardware drivers into the usual place in crypto/Kconfig. Acked-by: Herbert Xu Signed-off-by: Jason A.

crypto: s390 - add crypto library interface for ChaCha20

2022-05-13T09:24:49+00:00

Implement a crypto library interface for the s390-native ChaCha20 cipher algorithm. This allows us to stop to select CRYPTO_CHACHA20 and instead select CRYPTO_ARCH_HAVE_LIB_CHACHA. This allows BIG_KEYS=y not to build a whole ChaCha20 crypto infrastructure as a built-in, but build a smaller CRYPTO_LIB_CHACHA instead. Make CRYPTO_CHACHA_S390 config entry to look like similar ones on other architectures. Remove CRYPTO_ALGAPI select as anyway it is selected by CRYPTO_SKCIPHER. Add a new test module and a test script for ChaCha20 cipher and its interfaces.

crypto: xilinx: prevent probing on non-xilinx hardware

2022-03-09T03:12:31+00:00

The zynqmp-sha driver is always loaded and register its algorithm even on platform which do not have the proper hardware. This lead to a stacktrace due to zynqmp-sha3-384 failing its crypto self tests. So check if hardware is present via the firmware API call get_version. While at it, simplify the platform_driver by using module_platform_driver() Furthermore the driver should depend on ZYNQMP_FIRMWARE since it cannot work without it.

crypto: xilinx - Add Xilinx SHA3 driver

2022-03-02T22:49:21+00:00

This patch adds SHA3 driver support for the Xilinx ZynqMP SoC. Xilinx ZynqMP SoC has SHA3 engine used for secure hash calculation. The flow is SHA3 request from Userspace -> SHA3 driver-> ZynqMp driver-> Firmware -> SHA3 HW Engine SHA3 HW engine in Xilinx ZynqMP SoC, does not support parallel processing of 2 hash requests. Therefore, software fallback is being used for init, update, final, export and import in the ZynqMP SHA driver For digest, the calculation of SHA3 hash is done by the hardened SHA3 accelerator in Xilinx ZynqMP SoC.

s390/crypto: add SIMD implementation for ChaCha20

2021-12-06T13:42:24+00:00

Add an implementation of the ChaCha20 stream cipher (see e.g. RFC 7539) that makes use of z13's vector instruction set extension. The original implementation is by Andy Polyakov which is adapted for kernel use. Four to six blocks are processed in parallel resulting in a performance gain for inputs >= 256 bytes. chacha20-generic 1 operation in 622 cycles (256 bytes) 1 operation in 2346 cycles (1024 bytes) chacha20-s390 1 operation in 218 cycles (256 bytes) 1 operation in 647 cycles (1024 bytes) Cc: Andy Polyakov Reviewed-by: Harald Freudenberger Signed-off-by: Patrick Steuer Signed-off-by: Heiko Carstens

crypto: sl3516 - Add dependency on ARCH_GEMINI

The Storlink SL3516 crypto engine is only present on Storlink Semiconductor/Storm Semiconductor/Cortina Systems Gemini SoCs. Hence add a dependency on ARCH_GEMINI, to prevent asking the user about this driver when configuring a kernel without Gemini support. While at it, group the dependencies.
