Subject: [PATCH v2 00/13] Finish disentangling ChaCha, Poly1305, and BLAKE2s from CRYPTO
Date: Sun, 20 Apr 2025 12:25:56 -0700 [thread overview]
Message-ID: <20250420192609.295075-1-ebiggers@kernel.org> (raw)
This series removes the unnecessary dependency of the ChaCha, Poly1305,
and BLAKE2s library functions on the generic crypto infrastructure, i.e.
CONFIG_CRYPTO. To do this, it moves the architecture-optimized
implementations of these functions into new directories
arch/*/lib/crypto/ which do not depend on CRYPTO. This mirrors the
existing distinction between crypto/ and lib/crypto/.
The last two patches remove the selection of CRYPTO by CRYPTO_LIB_CHACHA
and CRYPTO_LIB_POLY1305, and they remove the corresponding *_INTERNAL
symbols which were needed only because of the entanglement with CRYPTO.
Note that Curve25519 is still entangled. Later patches will fix that.
Changed in v2:
- Introduced new directories arch/*/lib/crypto/ instead of keeping
the library functions in arch/*/crypto/.
Eric Biggers (13):
crypto: arm64 - drop redundant dependencies on ARM64
crypto: powerpc - drop redundant dependencies on PPC
crypto: s390 - drop redundant dependencies on S390
crypto: x86 - drop redundant dependencies on X86
crypto: arm - move library functions to arch/arm/lib/crypto/
crypto: arm64 - move library functions to arch/arm64/lib/crypto/
crypto: mips - move library functions to arch/mips/lib/crypto/
crypto: powerpc - move library functions to arch/powerpc/lib/crypto/
crypto: riscv - move library functions to arch/riscv/lib/crypto/
crypto: s390 - move library functions to arch/s390/lib/crypto/
crypto: x86 - move library functions to arch/x86/lib/crypto/
crypto: lib/chacha - remove INTERNAL symbol and selection of CRYPTO
crypto: lib/poly1305 - remove INTERNAL symbol and selection of CRYPTO
