[refpolicy] Basic policy for KDE and Konqueror, third look

[nicky726@gmail.com (Nicky726)]

Hello,

here I am again after some time, with my Konqueror policy related questions. I 
was too busy with the school, but by now I managed to incorporate almost all 
commets by Chris PeBenito, I only need to do some testing, which is where I 
got stuck again.

I've got this ugly hack just for testing purposes:

gen_require(`
               type unconfined_t;
               role unconfined_r;
       ')

konqueror_role(unconfined_r, unconfined_t)

in konqueror.te so that Konqueror is run in correct context. (work-in-progress 
.if file inculeded). Problem is that, when I run Konqueror, context is not 
changed, it still is unconfined... 

Did I missed some revolutionary change in refpolicy or Fedora in last 4 
months, which causes this, or have I some stupid mistake in my policy? 

I was also trying to put this konqueror_role call somewhere, where it should 
be -- not that I'm sure, where it is, as there is big difference between 
refpolicy and Fedora. To make it short there is too much code for me to 
follow, and too much changes in Fedora policy patches. How do the refpolicy 
developpers test their policies btw? 

Guess thats all for now. Thanks for your answers and patience,
Ondrej Vadinsky
