Function Documentation

◆ sendme_circuit_consider_sending()

void sendme_circuit_consider_sending	(	circuit_t *	circ,
		crypt_path_t *	layer_hint
	)

Check if the deliver_window for circuit circ (at hop layer_hint if it's defined) is low enough that we should send a circuit-level sendme back down the circuit. If so, send enough sendmes that the window would be overfull if we sent any more.

◆ sendme_circuit_data_received()

int sendme_circuit_data_received	(	circuit_t *	circ,
		crypt_path_t *	layer_hint
	)

Definition at line 620 of file sendme.c.

◆ sendme_connection_edge_consider_sending()

void sendme_connection_edge_consider_sending ( edge_connection_t * conn )

Called when we've just received a relay data cell, when we've just finished flushing all bytes to stream conn, or when we've flushed some bytes to the stream conn.

If conn->outbuf is not too full, and our deliver window is low, send back a suitable number of stream-level sendme cells.

	)

◆ sendme_process_circuit_level_impl()

int sendme_process_circuit_level_impl	(	crypt_path_t *	layer_hint,
		circuit_t *	circ
	)

Process a SENDME for Tor's original fixed window circuit-level flow control. Updates the package_window and ensures that it does not exceed the max.

Returns -END_CIRC_REASON_TORPROTOCOL if the max is exceeded, otherwise returns 0.
