Hi all,
I have problems in using Permission derived from java.security.Permission
with the felix ConditionalPermissionAdmin.
I have 3 bundles:
- PermissionManagement: defines MyPermission class and assigns this
permission to all bundles
- Provider: exposes a function f with security check on MyPermission
- Consumer: try to use function f
I run these bundles in felix + framework.security + scr and got access
denied
(Consumer is not allowed to use function f although MyPermission is
already assigned to all bundles)
Questions: How should I assign and check self-defined Permissions?
Any help is appreciated.
More infos to affected code snippets below.
Kind regards and thanks in advance
Hasan
Problems in detail:
I have a bundle named PermissionManagement which defines a new
Permission class
as follows:
public class MyPermission extends Permission {
private String actions;
public MyPermission(String name, String actions) {
super(name);
this.actions = actions;
System.out.println("MyPermission constructor called with params:
" +
name + ", " + actions);
}
...
@Override
public String getActions() {
System.out.println("MyPermission getActions method called");
return this.actions;
}
}
PermissionManagement also defines a class called "PermissionManager" to
assign
MyPermission to all bundles using ConditionalPermissionAdmin as follows:
cpa.addConditionalPermissionInfo(new ConditionInfo[]{
null
},
new PermissionInfo[]{
new PermissionInfo(
MyPermission.class.getName(), "MyName", "MyAction")
});
Provider bundle defines a class DummyProvider which exposes a function F
guarded with security check
public String f() {
MyPermission myPerm = new MyPermission("MyName", "MyAction");
SecurityManager security = System.getSecurityManager();
if (security != null) {
security.checkPermission(myPerm);
}
return "test";
}
Consumer bundle has an Activator as follows:
public class Activator implements BundleActivator {
@Override
public void start(BundleContext arg0) throws Exception {
DummyProvider dp = new DummyProvider();
System.out.println(dp.f());
}
...
}
in felix shell
-> start file:///.../consumer-1.0-SNAPSHOT.jar
DummyProvider constructor called
MyPermission constructor called with params: MyName, MyAction
MyPermission hashCode method called
MyPermission hashCode method called
MyPermission hashCode method called
MyPermission hashCode method called
MyPermission getActions method called
java.security.AccessControlException: access denied
(testbundles.permissionmanagement.MyPermission MyName MyAction)
