Comment 1 Daniel Walsh 2013-07-01 06:55:35 EDT
Very strange, you should not have gotten this avc

   type_transition cups_pdf_t user_home_dir_t : file user_home_t;  

Since we have these rules in policy.

This says that if cups_pdf_t tries to create a file in a directory labeled user_home_dir_t, it will get created as user_home_t.

At least in F19.

Miroslav are we missing these rules in F18?
Comment 2 Miroslav Grepl 2013-07-01 07:13:53 EDT
There was a different trans rule. Fixed.
