Typedef Documentation

◆ osmo_ss7_asp_rx_unknown_cb

typedef int osmo_ss7_asp_rx_unknown_cb(struct osmo_ss7_asp *asp, int ppid_mux, struct msgb *msg)

Weak function to handle payload for unknown/unsupported PPID or IPA StreamID.

This function can be overridden by application code to implement whatever handling it wants for such additional payloads/streams.

Parameters

[in]	asp	Application Server Process through which data was received
[in]	ppid_sid	SCTP PPID (in sigtran case) or IPA Stream ID
[in]	msg	Message buffer containing received data. Continues to be owned by caller!

Returns: 0 on success; negative on error

Function Documentation

◆ osmo_sccp_set_max_optional_data()

void osmo_sccp_set_max_optional_data	(	struct osmo_sccp_instance *	inst,
		int	val
	)

Adjust the upper bound for the optional data length (the payload) for CR, CC, CREF and RLSD messages.

For any Optional Data part larger than this value in octets, send CR, CC, CREF and RLSD messages without any payload, and send the data payload in a separate Data Form 1 message. ITU-T Q.713 sections 4.2 thru 4.5 define a limit of 130 bytes for the 'Data' parameter. This limit can be adjusted here. May be useful for interop with nonstandard SCCP peers.

Parameters

[in]	sccp	SCCP instance to reconfigure.
[in]	val	Number of bytes to set as upper bound for the optional data length, or pass a negative value to set the standard value of SCCP_MAX_OPTIONAL_DATA == 130, which conforms to ITU-T Q.713.

		int	default_local_port,
		const char *	default_local_ip,
		int	default_remote_port,
		const char *	default_remote_ip
	)

request an sccp client instance

Parameters

[in]	ctx	talloc context
[in]	name	human readable name
[in]	default_pc	pointcode to be used on missing VTY setting
[in]	prot	protocol to be used (e.g OSMO_SS7_ASP_PROT_M3UA)
[in]	default_local_port	local port to be used on missing VTY setting
[in]	default_local_ip	local IP-address to be used on missing VTY setting
[in]	default_remote_port	remote port to be used on missing VTY setting
[in]	default_remote_ip	remote IP-address to be used on missing VTY setting

Returns: callee-allocated SCCP instance on success; NULL on error

This is simplified version of osmo_sccp_simple_client_on_ss7_id(). the only difference is that the ID of the CS7 instance will be set to 0 statically

Parameters

[in]	ctx	talloc context
[in]	ss7_id	of the SS7/CS7 instance
[in]	name	human readable name
[in]	default_pc	pointcode to be used on missing VTY setting
[in]	prot	protocol to be used (e.g OSMO_SS7_ASP_PROT_M3UA)
[in]	default_local_port	local port to be used on missing VTY setting

Returns: callee-allocated SCCP instance on success; NULL on error

The function will examine the given CS7 instance and its sub components (as, asp, etc.). If necessary it will allocate the missing components. If no CS7 instance can be detected under the caller supplied ID, a new instance will be created beforehand.
