rpc: Fix serialization of NULL mechanism pointer #601

Closed ueno closed 9 months ago

ueno commented 9 months ago

A NULL mechanism pointer is valid for C_*Init functions to cancel the operation. Since 852ccd8d we encoded it with a CK_MECHANISM_TYPE 0 as an indicator, though it clashes with CKM_RSA_PKCS_KEY_PAIR_GEN (0). This patch changes the encoding to use a special value (0xffffffff) to indicate that and also properly advance the offset when reading.
