userhelper consolehelper role

[Matthew Ife]

It would appear that this is a new macro in fedora 13 but I dont believe
it is complete.

Whenever you run consolehelper from a RBAC account (in my case staff_t)
it does not work. When I ran audit2allow it was apparent a whole bunch
of different access vectors are needed to properly run graphical
utilities that might take advantage of consolehelper.

Running as sysadm_t was unaffected (I assume theres no transition in
this type to a consolehelper domain). I was running the command
"system-config-users" at the time.

Here is the audit2allow output. I've not sanitized this at all to find
out what is really relevent and what isnt.

require {
	type staff_t;
	type sysadm_t;
	type staff_consolehelper_t;
	type admin_home_t;
	type xdm_var_run_t;
	type xauth_exec_t;
	type xauth_home_t;
	class process { setsched transition };
	class capability { sys_nice chown dac_override };
	class dir { write search remove_name add_name };
	class shm { unix_read write unix_write read destroy create };
	class file { execute setattr read create execute_no_trans write getattr
link unlink open };
	role sysadm_r;
}
