The initial commit adding netlink callback handling also introduced memory leak issue. The python callback info was stored in an allocated structure, but that was never freed. Only exposing nl_cb_alloc() as is. nl_cb_get() is removed as it is not very useful to use reference counting mechanism. Python uses that itself internally. To deal properly with Python callback info the function nl_cb_put() and nl_cb_clone() have a custom wrapper taking care of Python reference counting. This commit also adds a Callback python class using the netlink callback functions. Signed-off-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: Thomas Graf <tgraf@suug.ch>
