Ma JieYue fdcf77659c xen-netfront: fix missing rx_refill_timer when allocate memory failed ... There was a bug in xennet_alloc_rx_buffers, when allocating page or sk_buff failed, and at the same time rx_batch queue not empty, the rx_refill_timer timer won't be scheduled. If finally the remaining request buffers in rx ring less than what backend driver expected, the backend driver would think of rx ring as full and start dropping packets. In such situation, there is no way for the netfront driver to recover automatically, so that the device can not work properly. The patch fixes the problem by always scheduling rx_refill_timer timer when alloc_page or __netdev_alloc_skb fails, no matter whether rx_batch queue is empty or not. It ensures that the rx ring request buffers will finally meet the backend needs. Signed-off-by: Ma JieYue <jieyue.majy@alibaba-inc.com> Signed-off-by: David S.
