2011-03-13vhost-net: remove unlocked use of receive_queueMichael S. Tsirkin
Use of skb_queue_empty(&sock->sk->sk_receive_queue) without taking the sk_receive_queue.lock is unsafe or useless. Take it out. Reported-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-03-13vhost: lock receive queue, not the socketJason Wang
vhost takes a sock lock to try and prevent the skb from being pulled from the receive queue after skb_peek. However this is not the right lock to use for that, sk_receive_queue.lock is. Fix that up. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-03-13vhost-net: Unify the code of mergeable and big buffer handlingJason Wang
Codes duplication were found between the handling of mergeable and big buffers, so this patch tries to unify them. This could be easily done by adding a quota to the get_rx_bufs() which is used to limit the number of buffers it returns (for mergeable buffer, the quota is simply UIO_MAXIOV, for big buffers, the quota is just 1), and then the previous handle_rx_mergeable() could be resued also for big buffers.

2011-03-13vhost-net: check the support of mergeable buffer outside the receive loopJason Wang
No need to check the support of mergeable buffer inside the recevie loop as the whole handle_rx()_xx is in the read critical region. So this patch move it ahead of the receiving loop. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-03-08vhost: copy_from_user -> __copy_from_userMichael S. Tsirkin
copy_from_user is pretty high on perf top profile, replacing it with __copy_from_user helps. It's also safe because we do access_ok checks during setup. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
