sc-hsm-pkcs11-test: "Find a private key after login" test failure on an empty token

[saper]

As of https://github.com/CardContact/sc-hsm-embedded/commit/4f26f202b28d5fe1c91a7a5b84061dd5b385b440 I get the following running the tests on an freshly initialized Nitrokey HSM 2:

Script started on Sat Jan 28 11:55:01 2023
Command: ./src/tests/sc-hsm-pkcs11-test --module src/pkcs11/.libs/libsc-hsm-pkcs11.so
 --pin 000000 --invasive
PKCS11 unit test running.

and then:

Find a private key after loginCalling C_FindObjectsInit - CKR_OK : Passed
Calling C_FindObjects - CKR_OK : Passed
Calling C_FindObjectsFinal - CKR_OK : Passed
- CKR_ARGUMENTS_BAD : Failed

Quick analysis:

At the time the testLogin() https://github.com/CardContact/sc-hsm-embedded/blob/4f26f202b28d5fe1c91a7a5b84061dd5b385b440/src/tests/sc-hsm-pkcs11-test.c#L2833 is run, there is no private key on the token at all.

If I run the following sequence instead:

radziecki> sc-hsm-tool --initialize --so-pin 3537363231383830 --pin 000000

...

then I finally get

Unit test finished.
455 tests performed.
0 tests failed.

[saper]

I have also noticed that if there is no AES key already, testAES() is skipped.

After adding the AES key, I got

Unit test finished.
472 tests performed.
0 tests failed.
