Subject: [PATCH 2/3] mok: fix the mirroring of RT variables
|
|
|
5b2885 |
|
|
|
5b2885 |
When there is no key in MokList, import_mok_state() just skipped MokList
|
|
|
5b2885 |
even though it should always mirror the vendor cert. Besides, the faulty
|
|
|
5b2885 |
check of 'present' and 'addend' invalidates the mirroring of MokListXRT,
|
|
|
5b2885 |
MokSBStateRT, and MokIgnoreDB.
