This driver provides an interface for storage driver to |
|
retrieve file-oriented encrypt keys from file system. |
|
The storage driver must register hardware encryption |
|
capability to HIE. |

Enable debug facility. Print logs when encryption, |
|
decryption, attach/retrieve key from bio. |

/d/hie/debug: debug log control |
|
Mask Debug Messages |
|
0x02 print logs when accessing certain inode. |
|
0x04 dump bio basic info when decrypt/encrypt. |
|
0x08 print keys when decrypt/encrypt. |
|
0x10 print pointer to the bio when decrypt/encrypt. |

Example: "echo 16 > /d/hie/debug" |
|
|
|
/d/hie/ino: target inode number, when log mask = 0x02. |

help |

Skip calling driver registered encryption/decryption |
|
function. Used to simulate theoretical speed limit of |
|
hardware encryption, that is, encryption overhead time |
|
equals zero. |

help |
|
XOR the buffer with 0xFFFF, instead of calling driver |
|
registered encryption/decryption function. Used to |
|
verify the correctness of hie_encrypt(), hie_decrypt() |
|
insertion points in the driver. |

XOR the buffer with real keys. Used to verify the |
|
correctness of key passing from the file system to |
|
the block layer, and finally to the HIE driver. |

XOR the buffer with the initialzation vector(iv.), |
|
if BC_IV_PAGE_IDX flag is set in the bio crypt |
|
context. Used to verify the correctness of iv. |
