[RFC] HFP support into oFono and BlueZ

[Denis Kenzior]

Hi Padovan,

Initial impressions:

+static DBusConnection *connection;
+static char *ofono_handsfree_path;
+
+
+static int timeout;
+

These globals seem to belong in per-modem user data unless you only want 1 HFP 
device per system?

+
+GIOChannel *g_at_get_channel_from_fd(int fd)
+{
+	GIOChannel *channel;
+	struct termios ti;
+
+	/* Switch TTY to raw mode */
+	memset(&ti, 0, sizeof(ti));
+	cfmakeraw(&ti);
+	tcflush(fd, TCIOFLUSH);
+	tcsetattr(fd, TCSANOW, &ti);
+
+	channel = g_io_channel_unix_new(fd);
+
+	if (channel == NULL) {
+		close(fd);
+		return NULL;
+	}
+
+	g_io_channel_set_close_on_unref(channel, TRUE);
+
+	return channel;
+}

Seriously, what are you trying to do here?  If you want a GIOChannel simply 
use g_io_channel_unix_new(fd) and pass it to gatchat.  See plugins/phonesim.c 
phonesim_enable() for details.  That operates on a TCP socket.

+struct ofono_modem *ofono_modem_get_by_path(const char *path);
+

You don't need this, see below.

+	g_dbus_register_interface(conn, obj_path, HFP_AGENT_INTERFACE,
+			agent_methods, NULL, NULL, data, NULL);
+

You can pass the modem object as userdata for the agent when registering the 
interface.  The modem will thus be available as 'data' in 
hfp_agent_new_connection, etc.
