Subject: [PATCH] FAPI: Fix execution of policy callback for reading PCR
|
||
|
|
registers.
|
||
|
|
|
||
|
|
For Policy PCR current PCR registers of the TPM registers can be used to compute
|
||
|
|
the policy digest. The counter in the computed PCR list was not set. Thus a empty
|
||
|
|
PCR list was used for the policy digest computation.
|
||
