Hello all. I have been playing with CIL on Selinux and have ran into a problem trying to convert the filetrans_pattern interface into a CIL macro.

The filetrans_pattern is as follows:

define(`filetrans_pattern',` allow $1 $2:dir rw_dir_perms; type_transition $1 $2:$4 $3 $5; ')

I converted that into a CIL macro like so:

(macro filetrans_pattern ((type ARG1)(type ARG2)(type ARG3)(class ARG4)(name ARG5)) (allow ARG1 ARG2 (dirs (rw))) (typetransition ARG1 ARG2 ARG4 ARG3 ARG5))

So far so good. The issue is when I try to call the Macro it says I am missing an argument and the .cil policy won't build. Here is my call statement:

(call filetrans_pattern (example_t example_tmp_t dir))

There are a couple of problems. First, you are calling the macro with only three arguments. Although the filename is optional for a typetransition rule, it is not in this case because CIL does not have optional arguments. If you do not want to specify a filename, then use "*". Second, the typetransition rule should be "(typetransition ARG1 ARG2 ARG4 ARG5 ARG3)"

It sounds like example_tmp_t is the result that you want. The second argument should be the type of the directory where the tmp directory is being created.

I want it so that whenever I run my process type of example_t it will transition into the example_tmp_t and store any tmp files inside of my newly created example_tmp_t directory. I know I'm missing something but can't figure out what. Let me know what you think.
