Subject: [PATCH] tpm2: update tpm2 test for supported commands
|
||
|
|
|
||
|
|
The test expects TPM2_CC_FIRST - 1 and TPM2_CC_LAST + 1 to be unsupported, but
|
||
|
|
those are not necessarily invalid commands. Instead test known-invalid
|
||
|
|
commands. Also add some more valid commands.
|
||
|
|
|
||
|
|
(cherry picked from commit 171d5b69c025c4a86a5100e9437b934ad84daca4)
