Handled IPv6 address after activating PDP context.
Received IPv6 address is of format addr + netmask in the same string
in the form of "a1.a2.a3.a4.a5.a6.a7.a8.a9.a10.a11.a12.a13.a14.a15.a16.
m1.m2.m3.m4.m5.m6.m7.m8.m9.m10.m11.m12.m13.m14.m15.m16"
the cb_data can be used by creating the structure with cb_data_new,
and then there are two possibilities:
- use it in a single callback function, and destroy it with a call to
g_free.
Example:
- calling function:
struct cb_data *cbd = cb_data_new(cb, data);
if (g_at_chat_send(chat, buf, NULL, at_cgatt_cb, cbd, g_free) > 0)
return;
g_free(cbd);
- called function (here at_cgatt_cb):
static void at_cgatt_cb(gboolean ok, GAtResult *result,
gpointer user_data)
{
struct cb_data *cbd = user_data;
ofono_gprs_cb_t cb = cbd->cb;
struct ofono_error error;
decode_at_error(&error,
g_at_result_final_response(result));
cb(&error, cbd->data);
}
note the absence of explicit g_free(cbd);
- pass it through a train of callback functions, adding a reference at
each pass cb_data_ref, and removing it with cb_data_unref.
the use of cb_data_ref would replace a new object creation, while the
use of cb_data_unref the use of g_free.
Example:
- calling function:
struct cb_data *cbd = cb_data_new(cb, data);
// no cb_ref at the creation
if (g_at_chat_send(chat, buf, NULL,
at_lte_set_default_attach_info_cb,
cbd, cb_data_unref) > 0)
goto end;
cb_data_unref(cbd);
- called function 1 (at_lte_set_default_attach_info_cb):
static void at_lte_set_default_attach_info_cb(gboolean ok,
GAtResult *result, gpointer user_data)
{
struct cb_data *cbd = user_data;
cbd = cb_data_ref(cbd);
if (g_at_chat_send(chat, buf, NULL,
at_cgatt_cb, cbd, cb_data_unref) > 0)
return;
cb_data_unref(cbd);
}
- called function 2 (at_cgatt_cb):
like above. no call to g_free or cb_data_unref. The terminal function
doesn't need to know about the reference scheme.
The function at_util_get_cgdcont_command computes the AT+CGDCONT
string, as per 3GPP 27.007.
It uses a second function, at_util_gprs_proto_to_pdp_type,
that returns the pdp_type string for the command
This function converts the ofono enum ofono_gprs_auth_method
into the value of the 3GPP 27.007 'auth_proto' variable of +CGAUTH so
that it can be passed directly to the AT command.

This utility will be used by HFP voicecall driver to compare
two calls. In some hardware, the call index may be shift when
a call transitions from waiting to incoming state (e.g. all other
held and active calls are released)
