[Xen-devel] encrypt data in blkfront.c

["tianjiangbo16898" <tianjiangbo16898@xxxxxxx>]

hello!

i am a junior in XEN. so some questions may be very junior too, please give me more patience.

 

I want to encrypt the data that will be written into the the disk, and the operation will happen in the Domain U's front-end driver.

and i notice that the write operation happens when the static int blkif_queue_request(struct request *req)   

 functions in blkfront.c File is called and the data is put into the struct request *req

 

I want to encrypt these data,  and i want to if the data is in virtual address of the guest Domain U or virtual address of the

the domain 0.

If I want to encrypt the data ,should I do operation on these virtual address directely or do it after doing some translation.

and do want translation.

 

please help!

Thanks very much!
