3.8.13.27 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Mateusz Guzik <mguzik@xxxxxxxxxx> commit a914722f333b3359d2f4f12919380a334176bb89 upstream. Otherwise the kernel oopses when remounting with IPv6 server because net is dereferenced in dev_get_by_name. Use net ns of current thread so that dev_get_by_name does not operate on foreign ns. Changing the address is prohibited anyway so this should not affect anything.
