Hi,

I am sorry if this is a newbie's question. I am developing a kernel module 
which needs to call some crypt functions implemented in user space. Since 
those functions utilize openssl library, I assume there is no easy way to 
port them into kernel.

I wonder whether there is an easy and elegant way to call the user space 
functions from the kernel and get the results, if /proc can not be used.  If 
anybody knows where I can find a crypt library in the kernel, that will be a 
great help too.

Thank you very much.

Xiaozhou Qiu
