Subject: [PATCH] tpm2: Return TPM_RC_VALUE upon decryption failure
|
||
|
|
|
||
|
|
When decryption fails then return TPM_RC_VALUE rather than TPM_RC_FAILURE.
|
||
|
|
The old error code could indicate to an application or driver that
|
||
|
|
something is wrong with the TPM (has possibly gone into failure mode) even
|
||
|
|
though only the decryption failed, possibly due to a wrong key.
