Hi, I am seeing funny QEMU behaviour when using "-net socket,listen" mechanism. When connecting and disconnecting several clients I start to get duplicated packets from QEMU server. IMHO, the following is happenning: 1. Client is disconnected: we get into net_socket_send callback. 2. net_socket_send does closesocket on the fd. 3. Note, that VLANClientState is not being removed. 4. New client is getting the same fd as the old client. 5. At this stage we have two VLANClientState's with the same fd. 6. From now on, every packet is being sent twice by qemu_vlan_deliver_packet. It seems that the fix would be to qemu_del_vlan_client on stage 3. It certainly fixes my problem. Thanks, Boris. PS.
