Hello,
I have set loglevel of NetworkManager to DEBUG to exact more information why nm-openvpn-service-openvpn-helper is unable to accomplish network interface configuration. Actually the device (tap0) created and would be available for further operations (ifup, route table update etc.) but somehow it never happens.
I cannot figure out actually the "call stack" among several external program calls, however I v found the particular error gets printed out
nm-udev-manager.c ::
/sys/devices/virtual/net/tap0: couldn't determine device driver; ignoring..., which led me to the global function call see beneath. Does any1 know if RedHat issue has been opened for such NetworkManager bug ?
Does any1 have idea why
Code:
const gchar *
g_udev_device_get_driver (GUdevDevice *device)
{
g_return_val_if_fail (G_UDEV_IS_DEVICE (device), NULL);
return udev_device_get_driver (device->priv->udevice);
}
this routine call fails and in the end I am getting
/sys/devices/virtual/net/tap0: couldn't determine device driver; ignoring... error message in the log, since *device is NULL?
As far as I am concerned the device_creator () invokes somehow the global routine above and if it is so, the device_creator() does not succeed anything and hands over the NULL pointer. Has anyone idea ?
