Function Documentation

assign_onionskin_to_cpuworker()

int assign_onionskin_to_cpuworker	(	or_circuit_t *	circ,
		create_cell_t *	onionskin
	)

Try to tell a cpuworker to perform the public key operations necessary to respond to onionskin for the circuit circ.

Return 0 if we successfully assign the task, or -1 on failure.

cpu_init()

void cpu_init

(

void

)

Initialize the cpuworker subsystem. It is OK to call this more than once during Tor's lifetime.

Definition at line 83 of file cpuworker.c.

cpuworker_cancel_circ_handshake()

void cpuworker_cancel_circ_handshake

(

or_circuit_t *

circ

)

If circ has a pending handshake that hasn't been processed yet, remove it from the worker queue.

cpuworker_log_onionskin_overhead()

void cpuworker_log_onionskin_overhead	(	int	severity,
		int	onionskin_type,
		const char *	onionskin_type_name
	)

If we've measured overhead for onionskins of type onionskin_type, log it.

cpuworker_queue_work()

struct workqueue_entry_t* cpuworker_queue_work	(	workqueue_priority_t	priority,
		workqueue_reply_t(*)(void *, void *)	fn,
		void(*)(void *)	reply_fn,
		void *	arg
	)

cpuworkers_rotate_keyinfo()

void cpuworkers_rotate_keyinfo

(

void

)

Called when the onion key has changed so update all CPU worker(s) with new function pointers with which a new state will be generated.

Definition at line 188 of file cpuworker.c.

estimated_usec_for_onionskins()

uint64_t estimated_usec_for_onionskins	(	uint32_t	n_requests,
		uint16_t	onionskin_type
	)

Return an estimate of how many microseconds we will need for a single cpuworker to process n_requests onionskins of type onionskin_type.
