This includes: - Use stronger typing in the SHA-224 and SHA-256 functions. - Add support for HMAC-SHA224 and HMAC-SHA256. (I'll send a separate patch with KUnit test cases for this.) - Make the old-school crypto API's support for sha224 and sha256 just use the actual library API, instead of unsafe low-level functions. - Consolidate the CPU-based SHA-224 and SHA-256 code into a single module, with better inlining and dead code elimination. - Properly document the SHA-224 and SHA-256 functions. - Other changes to synchronize the code with SHA-384 and SHA-512. Changed in v2: - Dropped sha224_kunit.c changes; it will be added later in the history - Dropped some patches that I folded into the SHA-512 series - Removed redundant checks of IS_ENABLED(CONFIG_KERNEL_MODE_NEON) - Removed obsolete setting of -DARCH for sha256.o - Fixed a commit title to mention sha256 instead of sha512 - Excluded HMAC-SHA{224,256} code from purgatory, where it isn't needed Eric Biggers (14): libceph: Rename hmac_sha256() to ceph_hmac_sha256() cxl/test: Simplify fw_buf_checksum_show() lib/crypto: sha256: Reorder some code lib/crypto: sha256: Remove sha256_blocks_simd() lib/crypto: sha256: Add sha224() and sha224_update() lib/crypto: sha256: Make library API use strongly-typed contexts lib/crypto: sha256: Propagate sha256_block_state type to implementations lib/crypto: sha256: Add HMAC-SHA224 and HMAC-SHA256 support crypto: sha256 - Wrap library and add HMAC support crypto: sha256 - Use same state format as legacy drivers lib/crypto: sha256: Remove sha256_is_arch_optimized() lib/crypto: sha256: Consolidate into single module lib/crypto: sha256: Sync sha256_update() with sha512_update() lib/crypto: sha256: Document the SHA-224 and SHA-256 API arch/mips/cavium-octeon/Kconfig | 6 - arch/mips/cavium-octeon/crypto/Makefile | 1 - arch/riscv/purgatory/purgatory.c | 8 +- arch/s390/purgatory/purgatory.c | 2 +- arch/x86/purgatory/purgatory.c | 2 +- crypto/Kconfig | 4 +- crypto/Makefile | 1 - crypto/sha256.c | 371 +++++++++------- crypto/testmgr.c | 12 + drivers/char/tpm/tpm2-sessions.c | 12 +- drivers/crypto/img-hash.c | 4 +- drivers/crypto/starfive/jh7110-hash.c | 8 +- include/crypto/internal/sha2.h | 66 --- include/crypto/sha2.h | 390 +++++++++++++++-- kernel/kexec_file.c | 10 +- lib/crypto/Kconfig | 34 +- lib/crypto/Makefile | 39 +- lib/crypto/arm/Kconfig | 7 - lib/crypto/arm/Makefile | 8 +- lib/crypto/arm/sha256-armv4.pl | 20 +- lib/crypto/arm/sha256-ce.S | 2 +- lib/crypto/arm/sha256.c | 64 --- lib/crypto/arm/sha256.h | 46 ++ lib/crypto/arm64/Kconfig | 6 - lib/crypto/arm64/Makefile | 9 +- lib/crypto/arm64/sha2-armv8.pl | 2 +- lib/crypto/arm64/sha256-ce.S | 2 +- lib/crypto/arm64/sha256.c | 75 ---- lib/crypto/arm64/sha256.h | 57 +++ lib/crypto/arm64/sha512.h | 6 +- .../crypto/mips/sha256.h | 20 +- lib/crypto/powerpc/Kconfig | 6 - lib/crypto/powerpc/Makefile | 3 - lib/crypto/powerpc/{sha256.c => sha256.h} | 19 +- lib/crypto/riscv/Kconfig | 8 - lib/crypto/riscv/Makefile | 3 - .../sha256-riscv64-zvknha_or_zvknhb-zvkb.S | 2 +- lib/crypto/riscv/sha256.c | 67 --- lib/crypto/riscv/sha256.h | 42 ++ lib/crypto/s390/Kconfig | 6 - lib/crypto/s390/Makefile | 3 - lib/crypto/s390/sha256.c | 47 -- lib/crypto/s390/sha256.h | 28 ++ lib/crypto/sha256-generic.c | 138 ------ lib/crypto/sha256.c | 413 ++++++++++++++++-- lib/crypto/sparc/Kconfig | 8 - lib/crypto/sparc/Makefile | 4 - lib/crypto/sparc/{sha256.c => sha256.h} | 37 +- lib/crypto/x86/Kconfig | 8 - lib/crypto/x86/Makefile | 3 - lib/crypto/x86/sha256-avx-asm.S | 2 +- lib/crypto/x86/sha256-avx2-asm.S | 2 +- lib/crypto/x86/sha256-ni-asm.S | 2 +- lib/crypto/x86/sha256-ssse3-asm.S | 2 +- lib/crypto/x86/sha256.c | 80 ---- lib/crypto/x86/sha256.h | 55 +++ net/ceph/messenger_v2.c | 12 +- tools/testing/cxl/test/mem.c | 21 +- 58 files changed, 1307 insertions(+), 1008 deletions(-) delete mode 100644 include/crypto/internal/sha2.h delete mode 100644 lib/crypto/arm/sha256.c create mode 100644 lib/crypto/arm/sha256.h delete mode 100644 lib/crypto/arm64/sha256.c create mode 100644 lib/crypto/arm64/sha256.h rename arch/mips/cavium-octeon/crypto/octeon-sha256.c => lib/crypto/mips/sha256.h (76%) rename lib/crypto/powerpc/{sha256.c => sha256.h} (76%) delete mode 100644 lib/crypto/riscv/sha256.c create mode 100644 lib/crypto/riscv/sha256.h delete mode 100644 lib/crypto/s390/sha256.c create mode 100644 lib/crypto/s390/sha256.h delete mode 100644 lib/crypto/sha256-generic.c delete mode 100644 lib/crypto/sparc/Kconfig delete mode 100644 lib/crypto/sparc/Makefile rename lib/crypto/sparc/{sha256.c => sha256.h} (53%) delete mode 100644 lib/crypto/x86/sha256.c create mode 100644 lib/crypto/x86/sha256.h -- 2.50.0
