Wei Xu says: ==================== vhost: fix a few skb leaks Matthew found a roughly 40% tcp throughput regression with commit c67df11f(vhost_net: try batch dequing from skb array) as discussed in the following thread: https://www.mail-archive.com/netdev@vger.kernel.org/msg187936.html v4: - fix zero iov iterator count in tap/tap_do_read()(Jason) - don't put tun in case of EBADFD(Jason) - Replace msg->msg_control with new 'skb' when calling tun/tap_do_read() v3: - move freeing skb from vhost to tun/tap recvmsg() to not confuse the callers. v2: - add Matthew as the reporter, thanks matthew. - moving zero headcount check ahead instead of defer consuming skb due to jason and mst's comment. - add freeing skb in favor of recvmsg() fails. ==================== Acked-by: Michael S.
