This series fixes some crashes when CONFIG_CFI_CLANG (Control Flow
Integrity) is enabled, with the new CFI implementation that was merged
in 6.1 and is supported on x86. 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.
Eric Biggers (11):
crypto: x86/aegis128 - fix 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: 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"
