Some of them were unconditional crashes, while others depended on whether the compiler optimized out the indirect calls or not. This series also simplifies some code that was intended to work around limitations of the old CFI implementation and is unnecessary for the new CFI implementation. Changed in v2: - Added patch "crypto: x86/sm4 - fix crash with CFI enabled" - Restored accidentally-deleted include of - Tweaked some commit messages and added Reviewed-by and Acked-by tags Eric Biggers (12): crypto: x86/aegis128 - fix possible crash with CFI enabled crypto: x86/aria - fix crash with CFI enabled crypto: x86/nhpoly1305 - eliminate unnecessary CFI wrappers crypto: x86/sha1 - fix possible crash with CFI enabled crypto: x86/sha256 - fix possible crash with CFI enabled crypto: x86/sha512 - fix possible crash with CFI enabled crypto: x86/sm3 - fix possible crash with CFI enabled crypto: x86/sm4 - fix crash with CFI enabled crypto: arm64/nhpoly1305 - eliminate unnecessary CFI wrapper crypto: arm64/sm3 - fix possible crash with CFI enabled crypto: arm/nhpoly1305 - eliminate unnecessary CFI wrapper Revert "crypto: shash - avoid comparing pointers to exported functions under CFI" arch/arm/crypto/nh-neon-core.S | 2 +- arch/arm/crypto/nhpoly1305-neon-glue.c | 11 ++--------- arch/arm64/crypto/nh-neon-core.S | 5 +++-- arch/arm64/crypto/nhpoly1305-neon-glue.c | 11 ++--------- arch/arm64/crypto/sm3-neon-core.S | 3 ++- arch/x86/crypto/aegis128-aesni-asm.S | 9 +++++---- arch/x86/crypto/aria-aesni-avx-asm_64.S | 13 +++++++------ arch/x86/crypto/nh-avx2-x86_64.S | 5 +++-- arch/x86/crypto/nh-sse2-x86_64.S | 5 +++-- arch/x86/crypto/nhpoly1305-avx2-glue.c | 11 ++--------- arch/x86/crypto/nhpoly1305-sse2-glue.c | 11 ++--------- arch/x86/crypto/sha1_ni_asm.S | 3 ++- arch/x86/crypto/sha1_ssse3_asm.S | 3 ++- arch/x86/crypto/sha256-avx-asm.S | 3 ++- arch/x86/crypto/sha256-avx2-asm.S | 3 ++- arch/x86/crypto/sha256-ssse3-asm.S | 3 ++- arch/x86/crypto/sha256_ni_asm.S | 3 ++- arch/x86/crypto/sha512-avx-asm.S | 3 ++- arch/x86/crypto/sha512-avx2-asm.S | 3 ++- arch/x86/crypto/sha512-ssse3-asm.S | 3 ++- arch/x86/crypto/sm3-avx-asm_64.S | 3 ++- arch/x86/crypto/sm4-aesni-avx-asm_64.S | 7 ++++--- arch/x86/crypto/sm4-aesni-avx2-asm_64.S | 7 ++++--- crypto/shash.c | 18 +++--------------- include/crypto/internal/hash.h | 8 +++++++- 25 files changed, 70 insertions(+), 86 deletions(-) base-commit: 75df46b598b5b46b0857ee7d2410deaf215e23d1
