From: Eric Biggers <ebiggers@xxxxxxxxxx> Move crypto_simd_disabled_for_test to lib/ so that crypto_simd_usable() can be used by library code. This was discussed previously (https://lore.kernel.org/linux-crypto/20220716062920.210381-4-ebiggers@xxxxxxxxxx/) but was not done because there was no use case yet. However, this is now needed for the arm64 CRC32 library code. Tested with: export ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- echo CONFIG_CRC32=y > .config echo CONFIG_MODULES=y >> .config echo CONFIG_CRYPTO=m >> .config echo CONFIG_DEBUG_KERNEL=y >> .config echo CONFIG_CRYPTO_MANAGER_DISABLE_TESTS=n >> .config echo CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y >> .config make olddefconfig make -j$(nproc) Signed-off-by: Eric Biggers <ebiggers@xxxxxxxxxx> --- crypto/algapi.c | 6 ------ lib/crypto/Makefile | 2 ++ lib/crypto/simd.c | 11 +++++++++++ 3 files changed, 13 insertions(+), 6 deletions(-) create mode 100644 lib/crypto/simd.c diff --git a/crypto/algapi.c b/crypto/algapi.c index 74e2261c184ca..429a832f90fe0 100644 --- a/crypto/algapi.c +++ b/crypto/algapi.c @@ -4,11 +4,10 @@ * * Copyright (c) 2006 Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> */ #include <crypto/algapi.h> -#include <crypto/internal/simd.h> #include <linux/err.h> #include <linux/errno.h> #include <linux/fips.h> #include <linux/init.h> #include <linux/kernel.h> @@ -21,15 +20,10 @@ #include "internal.h" static LIST_HEAD(crypto_template_list); -#ifdef CONFIG_CRYPTO_MANAGER_EXTRA_TESTS -DEFINE_PER_CPU(bool, crypto_simd_disabled_for_test); -EXPORT_PER_CPU_SYMBOL_GPL(crypto_simd_disabled_for_test); -#endif - static inline void crypto_check_module_sig(struct module *mod) { if (fips_enabled && mod && !module_sig_ok(mod)) panic("Module %s signature verification failed in FIPS mode\n", module_name(mod)); diff --git a/lib/crypto/Makefile b/lib/crypto/Makefile index 969baab8c805f..01fac1cd05a19 100644 --- a/lib/crypto/Makefile +++ b/lib/crypto/Makefile @@ -56,5 +56,7 @@ libblake2s-y += blake2s-selftest.o libchacha20poly1305-y += chacha20poly1305-selftest.o libcurve25519-y += curve25519-selftest.o endif obj-$(CONFIG_MPILIB) += mpi/ + +obj-$(CONFIG_CRYPTO_MANAGER_EXTRA_TESTS) += simd.o diff --git a/lib/crypto/simd.c b/lib/crypto/simd.c new file mode 100644 index 0000000000000..9c36cb3bb49c4 --- /dev/null +++ b/lib/crypto/simd.c @@ -0,0 +1,11 @@ +// SPDX-License-Identifier: GPL-2.0-or-later +/* + * SIMD testing utility functions + * + * Copyright 2024 Google LLC + */ + +#include <crypto/internal/simd.h> + +DEFINE_PER_CPU(bool, crypto_simd_disabled_for_test); +EXPORT_PER_CPU_SYMBOL_GPL(crypto_simd_disabled_for_test); base-commit: 5c20772738e1d1d7bec41664eb9d61497e53c10e -- 2.47.0
