Re: Cil Macros

The only thing I am confused on now is on what to put for the "ARG" statements. Now when it says "ARG1" am I supposed to put my mytest_t type there or just leave it as it says like ARG1? I took out the typeattributeset statement like you said and tried to build it with the following, but it still failed. Thanks.

(macro mytest_t_domain_auto_trans ((type ARG1))
  (call domain_trans (type ARG1))
  (allow ARG1  mytest_t (process (exec read write getattr transition)))
)

Hello everyone, I've been trying to play around with macros with the CIL
language and have come across some problems on how they work. I'm just trying to simple create a macro that will do a type transition with a process called
mytest_t domain.

Here is what I have so far:




(macro mytest_t_domain_auto_trans ((ARG1))
   (typeattributeset cil_gen_require application_domain_type)
   (call domain_trans (ARG1))
   (allow ARG1 mytest_t (process (exec read write getattr transition)))
)


You are probably getting a message saying invalid syntax.
The macro definition needs to say what the argument is, like this:
(macro mytest_t_domain_auto_trans ((type ARG1))

We use (typeattributeset cil_gen_require SOME_TYPE) when converting pp files to cil to make optional blocks work when a type is required, but not used. I don't think that you need it here.

I hope that helps.

...but when I try to run it it obviously doesn't work. If anyone has any input
on what I am doing wrong I'm all ears. Thanks.
