Hi Abhijit and Saket, Thank you very much for your reply! I did some study on eCryptfs before. I think eCrytfs is a " big ideas for small business". Implementation of a totally new filesystem is quite complex for me to imitate and study. So with the elicitation from eCryptfs, I have this idea to design a simplified module(not another filesystem) to do transparent en/decrypting, by replacing some main function pointers. Thanks to you, now I know there is WRAPFS, which I think is perfectly suitable for my project－－short, easy, and highly extendable. If I still cannot fix this problem, I would like to turn to WRAPFS! Much thanks! Freeman Zhang _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
