Mikhail Petrov updated IGNITE-15322:
------------------------------------
    Description: 
For example, this code needs TASK_EXECUTE permissions.
{code:java}
Affinity affinity = ignite.affinity("TEST");
affinity.mapKeysToNodes(Arrays.asList(1L,100L, 1000L));{code}
This is unexpected behavior, because:
 - the task started implicitly (under the hood), customer should not to know 
about it.
 - this is a system task (not defined by a customer), the tasks needs for a 
normal grid workflow.

Also, I suppose there are any other implicitly tasks, which could lead to 
unexpected behavior (need permissions).

Proposed way to solve this issue:
1. Add mechanism to destinguish whether task class is SYSTEM (part of the 
Ignite codebase) or USER.

Here we can reuse SecurityUtils#isSystemType mechanism that is used in Ignite 
Sanbox implementation.

2. Add mechanism to detect if task execution was initiated by the user (PUBLIC 
CALL) or by the Ignite system itself (INTERNAL CALL).

It seems that the easiest way to achieve this is to completely separate the 
public and private Compute APIs. 
Task executioin requests received through Ignite Thin Clients are considered 
PUBLIC CALLs.

The first two steps give us the ability to 
A. safely skip authorization of SYSTEM tasks which are 
called through INTERNAL API.
B. keep authorization of PUBLIC tasks intact
C. prevent users of calling SYSTEM tasks directly through PUBLIC API ( it means 
that all user task execution requests received through REST or Thin client 
protocols MUST be executed through PUBLIC API).

3. Add the ability to explicitly specify for SYSTEM 
task/callable/runnable/closure what permission should be checked before its 
execution. 

It can be solved by introducing optional interface that compute job can 
implement.
{code:java}
/** */
public interface PublicAccessJob {
     /** */
    public SecurityPermissionSet requiredPermissions();
}
{code}
4. SYSTEM tasks can splitted into two categories - 
SYSTEM INTERNAL (tasks that are not available to the user) and SYSTEM PUBLIC 
tasks (tasks that are part oof the ignite code but are available to the user 
and can be executed through the PUBLIC API)

Example of SYSTEM public tasks - Visor tasks on which the user control script 
is implemented

They are executed through Thin Client which is considered Public API.

Considering that SYSTEM PUBLIC tasks can potentially be executed by the user, 
we must force the developer to explicitly specify permissions for tasks of this 
type. It can be done by checking that SYSTEM tasks that are executed through 
PUBLIC API impelements PublicAwareJob interface described above.
||X||Public API||Private API||
|PUBLIC task|auth by task name|restricted|
|SYSTEM INTERNAL task|restricted|auth skipped|
|SYSTEM PUBLIC task|auth by explicitly specified permissions|auth skipped|

By the way the PublicAccessJob interface, implemented by all Visor jobs, allows 
you to specify for each specific Visor job what permissions it requires. Also 
it is proposed to guard all Visor Jobs with ADMIN_OPS permission by default.

5. Authorization of SYSTEM tasks cancellation must be skipped it they are 
canceled by the same user who started them, oterwise dedicated permissions is 
required (e.g. ADMIN_KILL). USER tasks cancellation is performed by their names.

Possible troubles:

1. Mentioned SecurityUtils#isSystemType works only for the ignite-core module. 
If some tasks are defined inside other Ignite modules - they will not be 
considered SYSTEM. Currently there are no such task.

2. Currently all DotNet code is wrapped and executed via special SYSTEM tasks. 
As a result all DotNet runnable/callable/tasks are authorized by the name of 
the SYSTEM wrapper task. So if TASK_EXECUTE permissions for the SYSTEM wrapper 
task is granted - user can execute whathever DotNet custom tas he wants. After 
the propsed changes SYTEM task authorization will no more.be performed. So 
DotNet custom code execution will become completeley unauthorised. We should 
fix it in a separate ticket.
