216a7795ec210bdabd5dad42323eee70bbfc8d90 - crypto: hisi-trng - Remove crypto_rng interface

Sat, 30 May 2026 22:26:23 +0200

crypto: hisi-trng - Remove crypto_rng interfacedrivers/crypto/hisilicon/trng/trng.c exposes the same hardware throughtwo completely separate interfaces, crypto_rng and hwrng. However, theimplementation of this is buggy because it permits generation operationsfrom these interfaces to run concurrently with each other, accessing thesame registers. That is, hisi_trng_generate() synchronizes with itselfbut not with hisi_trng_read(). This results in potential repetition ofoutput from the RNG, output of non-random values, etc.Fortunately, there's actually no point in hardware RNG driversimplementing the crypto_rng interface. It's not actually used byanything besides the "rng" algorithm type of AF_ALG, which in turn isnot actually used in practice. Other crypto_rng hardware drivers arelikewise 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.Fixes: e4d9d10ef4be ("crypto: hisilicon/trng - add support for PRNG")Cc: stable@vger.kernel.orgSigned-off-by: Eric Biggers Signed-off-by: Herbert Xu List of files: /linux/drivers/crypto/hisilicon/Kconfig

crypto: hisilicon/zip - add lz4 algorithm for hisi_zipAdd the "hisi-lz4-acomp" algorithm by the crypto acomp. When the8th bit of the capability register is 1, the lz4 algorithm willregister to crypto acomp, and the window length is configured to16K by default.Since the "hisi-lz4-acomp" currently only support compressiondirection, decompression is completed by the soft lz4 algorithm.Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu List of files: /linux/drivers/crypto/hisilicon/Kconfig

hwrng: histb - Move driver to drivers/char/hw_random/histb-rng.cMove to drivers/char/hw_random since histb-(t)rng does not providecryptography pseudo rng.histb-rng is pretty like hisi-rng, but after investigation, we confirmthere is no RNG_PHY_SEED register on histb-rng so a separate driver isneeded.Still we rename relevant function names to match those in hisi-rng.Link: https://lore.kernel.org/r/20230401164448.1393336-1-mmyangfl@gmail.comSigned-off-by: David Yang Signed-off-by: Herbert Xu List of files: /linux/drivers/crypto/hisilicon/Kconfig

Wed, 11 Jan 2023 13:02:03 +0100

crypto: hisilicon - remove redundant config PCI dependency for some CRYPTO_DEV_HISI configsWhile reviewing dependencies in some Kconfig files, I noticed the redundantdependency "depends on PCI && PCI_MSI". The config PCI_MSI has always,since its introduction, been dependent on the config PCI. So, it issufficient to just depend on PCI_MSI, and know that the dependency on PCIis 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.Signed-off-by: Lukas Bulwahn Acked-by: Weili Qian Signed-off-by: Herbert Xu List of files: /linux/drivers/crypto/hisilicon/Kconfig
