Subject: [PATCH 34/34] EP11: Fix setting unknown CPs to ON
|
|
|
253609 |
|
|
|
253609 |
The very last control point must also be applied from the queried bits to
|
|
|
253609 |
the combined bits. Otherwise the very last control point is always treated
|
|
|
253609 |
as being ON, although it might be OFF, and this can lead to mechanisms being
|
|
|
253609 |
used that are disabled by that control point.
|
|
|
253609 |
|
|
|

Fixes https://github.com/opencryptoki/opencryptoki/commit/97248f73495695436f11fafd74c2ec41a5a6f796
