Helper function which determines whether the capabilities of the |

OEM Token are sufficient to permit debug of an application. |
|
579 |
||
580 |
Normally, we use the AllFiles capability as a proxy which |
|
581 |
means a Debug Agent can debug non-debuggable executables, |
|
582 |
provided it has a superset of the capabilities of the executable |
|
583 |
to be debugged. |
|
584 |
||
585 |
However, this causes the problem that all OEM Debug Tokens implicitly |
|
586 |
give the power to debug an AllFiles executable, even if all that |
|
587 |
is really needed is the power to debug an app with no capabilities, |
|
588 |
or capabilities other than AllFiles. |
|
589 |
||
590 |
To address this, we treat the AllFiles capability in a special way. |
|
591 |
The AllFiles capability in a token is taken to mean that an OEM has |
|
592 |
signed the token, and hence can debug other executables. But this does |
|
593 |
not inclue the ability to debug an AllFiles executable. To debug an AllFiles |
|
594 |
executable, the token must also have TCB. |
