[ Upstream commit d6b83f1e3707c4d60acfa58afd3515e17e5d5384 ] If failed to allocate "tags" or could not find the final upper device from start_dev's upper list in bond_verify_device_path(), only the loopback detection of the current upper device should be affected, and the system is no need to be panic. So return -ENOMEM in alb_upper_dev_walk to stop walking, print some warn information when failed to allocate memory for vlan tags in bond_verify_device_path. I also think that the following function calls netdev_walk_all_upper_dev_rcu ---->>>alb_upper_dev_walk ---------->>>bond_verify_device_path From this way, "end device" can eventually be obtained from "start device" in bond_verify_device_path, IS_ERR(tags) could be instead of IS_ERR_OR_NULL(tags) in alb_upper_dev_walk.
