This serial of patches enables the SM4-XTS algorithm in blk-crypto and enables the SM4-XTS/CTS algorithm in fscrypt to encrypt file content and filename. v2 change: - As Eric said, the new FSCRYPT_MODE is defined for the unused numbers 7 and 8 Tianjia Zhang (2): blk-crypto: Add support for SM4-XTS blk crypto mode fscrypt: Add SM4 XTS/CTS symmetric algorithm support Documentation/filesystems/fscrypt.rst | 1 + block/blk-crypto.c | 6 ++++++ fs/crypto/keysetup.c | 15 +++++++++++++++ fs/crypto/policy.c | 4 ++++ include/linux/blk-crypto.h | 1 + include/uapi/linux/fscrypt.h | 2 ++ 6 files changed, 29 insertions(+)
