[rsbac] REG module

[Tommy]

I'm writing a module using the reg facilities, but I'm finding a lot of 
difficulties in changing the uid of the process using the syscall registered 
by the module. I use current->uid = the_other_uid, but the uid doesn't change 
and I don't get any other RSBAC module complaining (well, it would be very 
difficult, as I'm just changing an integer value...). I would also like to 
know how I could do such change whitout bypassing the other modules. Should I 
use rsbac_adf_request() for a simple check before changing the uid or is 
there another way?

P.S.: As you've probably already understood I'm a newbie to both rsbac and 
kernel programming :)
