net-sysfs: initialize uid and gid before calling net_ns_get_ownership
commit f7a1e76d upstream. Currently in net_ns_get_ownership() it may not be able to set uid or gid if make_kuid or make_kgid returns an invalid value, and an uninit-value issue can be triggered by this. This patch is to fix it by initializing the uid and gid before calling net_ns_get_ownership(), as it does in kobject_get_ownership() Fixes: e6dee9f3 ("net-sysfs: add netdev_change_owner()") Reported-by:Paolo Abeni <pabeni@redhat.com> Signed-off-by:
