[PATCH v4 0/2] Add SM4 XTS symmetric algorithm for blk-crypto and fscrypt

From: Tianjia Zhang
Date: Thu Dec 01 2022 - 07:58:32 EST


SM4 is widely used in China's data encryption software and hardware.
these algoritms are mandatory in many scenarios. 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.

v4 changes:
- only allow the SM4 XTS/CTS algorithm in policy v2 for fscrypt
- update git commit message

v3 change:
- update git commit message

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
