22cf7053 - crypto: chacha - unexport chacha_generic routines

crypto: chacha - unexport chacha_generic routinesNow that all users of generic ChaCha code have moved to the core library,there is no longer a need for the generic ChaCha skcpiher driver toexport parts of it implementation for reuse by other drivers. So dropthe exports, and make the symbols static.Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu List of files: /linux-6.15/include/crypto/internal/chacha.h

5fb8ef25 - crypto: chacha - move existing library code into lib/crypto

Fri, 08 Nov 2019 12:22:08 +0000

crypto: chacha - move existing library code into lib/cryptoCurrently, our generic ChaCha implementation consists of a permutefunction in lib/chacha.c that operates on the 64-byte ChaCha statedirectly [and which is always included into the core kernel since itis used by the /dev/random driver], and the crypto API plumbing toexpose it as a skcipher.In order to support in-kernel users that need the ChaCha streamcipherbut have no need [or tolerance] for going through the abstractions ofthe crypto API, let's expose the streamcipher bits via a library APIas well, in a way that permits the implementation to be superseded byan architecture specific one if provided.So move the streamcipher code into a separate module in lib/crypto,and expose the init() and crypt() routines to users of the library.Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu List of files: /linux-6.15/include/crypto/internal/chacha.h
