hwrng: hisi-trng - Move hisi-trng into drivers/char/hw_random/

2026-06-11T06:02:58+00:00

Since this file just implements a hwrng driver, move it into drivers/char/hw_random/. Rename the kconfig option accordingly as well. Note that this moves the file back to its original location. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: hisi-trng - Remove crypto_rng interface

2026-06-11T05:53:59+00:00

drivers/crypto/hisilicon/trng/trng.c exposes the same hardware through two completely separate interfaces, crypto_rng and hwrng. However, the implementation of this is buggy because it permits generation operations from these interfaces to run concurrently with each other, accessing the same registers. That is, hisi_trng_generate() synchronizes with itself but not with hisi_trng_read(). This results in potential repetition of output from the RNG, output of non-random values, etc. Fortunately, there's actually no point in hardware RNG drivers implementing the crypto_rng interface. It's not actually used by anything besides the "rng" algorithm type of AF_ALG, which in turn is not actually used in practice. Other crypto_rng hardware drivers are likewise being phased out, leaving just the hwrng support. Thus, remove it to simplify the code and avoid conflict (and confusion) with the hwrng interface which is the one that actually matters.

crypto: hisilicon/zip - add lz4 algorithm for hisi_zip

2026-01-31T02:52:31+00:00

Add the "hisi-lz4-acomp" algorithm by the crypto acomp. When the 8th bit of the capability register is 1, the lz4 algorithm will register to crypto acomp, and the window length is configured to 16K by default. Since the "hisi-lz4-acomp" currently only support compression direction, decompression is completed by the soft lz4 algorithm. Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/zip - support fallback for zip

2026-01-16T06:02:06+00:00

When the hardware queue resource busy(no shareable queue) or memery alloc fail in initialization of acomp_alg, use soft algorithm to complete the work. Fixes: 1a9e6f59caee ("crypto: hisilicon/zip - remove zlib and gzip") Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/hpre - Remove unused curve25519 kpp support

2025-09-06T21:45:49+00:00

Curve25519 is used only via the library API, not the crypto_kpp API. In preparation for removing the unused crypto_kpp API for Curve25519, remove the unused "hpre-curve25519" kpp algorithm.

hwrng: histb - Move driver to drivers/char/hw_random/histb-rng.c

2023-05-12T10:48:01+00:00

Move to drivers/char/hw_random since histb-(t)rng does not provide cryptography pseudo rng. histb-rng is pretty like hisi-rng, but after investigation, we confirm there is no RNG_PHY_SEED register on histb-rng so a separate driver is needed. Still we rename relevant function names to match those in hisi-rng. Link: https://lore.kernel.org/r/20230401164448.1393336-1-mmyangfl@gmail.com Signed-off-by: David Yang Signed-off-by: Herbert Xu

crypto: hisilicon - remove redundant config PCI dependency for some CRYPTO_DEV_HISI configs

2023-01-20T10:29:31+00:00

While reviewing dependencies in some Kconfig files, I noticed the redundant dependency "depends on PCI && PCI_MSI". The config PCI_MSI has always, since its introduction, been dependent on the config PCI. So, it is sufficient to just depend on PCI_MSI, and know that the dependency on PCI is implicitly implied. Reduce the dependencies of configs CRYPTO_DEV_HISI_SEC2, CRYPTO_DEV_HISI_QM, CRYPTO_DEV_HISI_ZIP and CRYPTO_DEV_HISI_HPRE. No functional change and effective change of Kconfig dependendencies.

crypto: ccree,hisilicon - Fix dependencies to correct algorithm

2022-12-02T10:12:41+00:00

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.
