Ken-ichirou MATSUZAWA 0ef707700f netlink: rx mmap: fix POLLIN condition ... Poll() returns immediately after setting the kernel current frame (ring->head) to SKIP from user space even though there is no new frame. And in a case of all frames is VALID, user space program unintensionally sets (only) kernel current frame to UNUSED, then calls poll(), it will not return immediately even though there are VALID frames. To avoid situations like above, I think we need to scan all frames to find VALID frames at poll() like netlink_alloc_skb(), netlink_forward_ring() finding an UNUSED frame at skb allocation.
