It can also be retrieved from: git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git curve25519-v2 This series removes the unused crypto_kpp support for Curve25519, migrates curve25519-selftest to a KUnit test suite, and reorganizes the generic and arch-optimized Curve25519 code to all be located in lib/crypto/ and built into a single libcurve25519 module. Changed from v1: - Split kpp removal into multiple patches - Don't select CRYPTO_LIB_CURVE25519_GENERIC from KUnit test - Removed unnecessary parameter from hpre_ecc_clear_ctx() - Removed unnecessary 'return' from arm curve25519_base_arch() - Updated file comment in lib/crypto/curve25519.c - Made kconfig help text for KUnit test more consistent with other tests - Used initializer in test_curve25519() - Removed unnecessary newlines from messages in test_curve25519() - Use NSEC_PER_SEC instead of literal 1000000000 - Added an Acked-by Eric Biggers (12): crypto: hisilicon/hpre - Remove unused curve25519 kpp support crypto: arm/curve25519 - Remove unused kpp support crypto: powerpc/curve25519 - Remove unused kpp support crypto: x86/curve25519 - Remove unused kpp support crypto: testmgr - Remove curve25519 kpp tests crypto: curve25519 - Remove unused kpp support lib/crypto: tests: Migrate Curve25519 self-test to KUnit lib/crypto: tests: Add Curve25519 benchmark lib/crypto: curve25519: Move a couple functions out-of-line lib/crypto: curve25519: Consolidate into single module lib/crypto: tests: Enable Curve25519 test when CRYPTO_SELFTESTS wireguard: kconfig: Simplify crypto kconfig selections arch/arm/crypto/Kconfig | 13 - arch/arm/crypto/Makefile | 2 - arch/arm/crypto/curve25519-glue.c | 137 -- arch/m68k/configs/amiga_defconfig | 1 - arch/m68k/configs/apollo_defconfig | 1 - arch/m68k/configs/atari_defconfig | 1 - arch/m68k/configs/bvme6000_defconfig | 1 - arch/m68k/configs/hp300_defconfig | 1 - arch/m68k/configs/mac_defconfig | 1 - arch/m68k/configs/multi_defconfig | 1 - arch/m68k/configs/mvme147_defconfig | 1 - arch/m68k/configs/mvme16x_defconfig | 1 - arch/m68k/configs/q40_defconfig | 1 - arch/m68k/configs/sun3_defconfig | 1 - arch/m68k/configs/sun3x_defconfig | 1 - arch/powerpc/crypto/Kconfig | 13 - arch/powerpc/crypto/Makefile | 2 - arch/s390/configs/debug_defconfig | 1 - arch/s390/configs/defconfig | 1 - arch/x86/crypto/Kconfig | 13 - arch/x86/crypto/Makefile | 5 - crypto/Kconfig | 8 - crypto/Makefile | 1 - crypto/curve25519-generic.c | 91 -- crypto/testmgr.c | 6 - crypto/testmgr.h | 1225 ----------------- drivers/crypto/hisilicon/Kconfig | 1 - drivers/crypto/hisilicon/hpre/hpre_crypto.c | 403 +----- drivers/net/Kconfig | 15 +- include/crypto/curve25519.h | 40 +- lib/crypto/Kconfig | 37 +- lib/crypto/Makefile | 27 +- .../crypto/arm}/curve25519-core.S | 0 lib/crypto/arm/curve25519.h | 47 + lib/crypto/curve25519-generic.c | 25 - lib/crypto/curve25519.c | 69 +- .../crypto/powerpc}/curve25519-ppc64le_asm.S | 0 .../crypto/powerpc/curve25519.h | 124 +- lib/crypto/tests/Kconfig | 9 + lib/crypto/tests/Makefile | 1 + .../curve25519_kunit.c} | 99 +- .../crypto/x86/curve25519.h | 127 +- 42 files changed, 236 insertions(+), 2318 deletions(-) delete mode 100644 arch/arm/crypto/curve25519-glue.c delete mode 100644 crypto/curve25519-generic.c rename {arch/arm/crypto => lib/crypto/arm}/curve25519-core.S (100%) create mode 100644 lib/crypto/arm/curve25519.h delete mode 100644 lib/crypto/curve25519-generic.c rename {arch/powerpc/crypto => lib/crypto/powerpc}/curve25519-ppc64le_asm.S (100%) rename arch/powerpc/crypto/curve25519-ppc64le-core.c => lib/crypto/powerpc/curve25519.h (56%) rename lib/crypto/{curve25519-selftest.c => tests/curve25519_kunit.c} (96%) rename arch/x86/crypto/curve25519-x86_64.c => lib/crypto/x86/curve25519.h (94%) base-commit: 362f92286065d9f8282da5def89e173a12191568 -- 2.50.1
