pc_ssh_server_dispatch()

int pc_ssh_server_dispatch	(	uint8_t	i,
		uint8_t	msg_type,
		const uint8_t *	payload,
		size_t	len
	)

Dispatch one decrypted inbound SSH message for slot i.

Routes by message type and handshake phase, driving the handshake and, once open, the channel protocol. Responses are produced via the emit callback.

Parameters

[in]	i	SSH slot.
[in]	msg_type	First payload byte (SSH message number).
[in]	payload	Full message payload (including msg_type at [0]).
[in]	len	Payload length.

Returns

0 if handled, -1 if the connection must be closed.
