I looked at the patch/source, but I cannot test.
The Problem is, my StarCos 3.2 card currently does not
work with the D-Trust starcos 3.4 driver.

I would have expected a different handling, with
callback functions on the card driver level ,eg:

// callbacks into card plugins.

typedef void* sc_card_state_t;

sc_card_state_t* card_alloc_state();
card_free_state(sc_card_state_t* sc_card_state);

int card_save_state(void** ptr);
int card_restore_state(void* ptr);

Where the driver can store "what is needed" for this card.
The pkcs11 layer then have to keep track for the slot<->void pointer, with
a hash.

If a card supports auth cookies, it can do that in the void pointer, or if
not
it can store the directory/pin.
This means the pkcs11 layer does not know about: "struct sc_pkcs11_login",
but only
manages a dummy typedef.

Martin
