/*
 * Dual-Function Cryptographic Functions
 * (as defined in PKCS#11 spec section 11.13)
 *
 * These functions will not be supported in the this release.
 * A call to these functions returns CKR_FUNCTION_NOT_SUPPORTED.
 *
 * Providing the support for dual-function crypto functions is
 * not trivial.  C_FooInit() need to be called for the 2 crypto
 * operations before any of these function can be called.
 * When C_FooInit() is called, metaslot doesn't know if it is going
 * to do dual-function crypto or single crypto operation.
 * So, it has no way to pick the slot that supports both the mechanism
 * it specified and supports dual-functions.
 *
 * In order for these dual functions to be supported in the future,
 * metaslot need to simulate the dual-function crypto operations
 * when both operations are not lucky enough be to initialized in
 * the same slots that supports dual-functions.
