The underlying nlmsg_multicast() already sets sk->sk_err for us to notify socket overruns, so we should not do anything with this return value. So we just call nfnetlink_set_err() if: 1) We fail to allocate the netlink message. or 2) We don't have enough space in the netlink message to place attributes, which means that we likely need to allocate a larger message. Before this patch, the internal ESRCH netlink error code was propagated to userspace, which is quite misleading. Netlink semantics mandate that listeners just hit ENOBUFS if the socket buffer overruns.
