Abstract: A method of transmitting data for use at a data processing system and network interface device, the data processing system being coupled to a network by the network interface device, the method comprising: forming a message template in accordance with a predetermined set of network protocols, the message template including at least in part one or more protocol headers; forming an application layer message in one or more parts; updating the message template with the parts of the application layer message; processing the message template in accordance with the predetermined set of network protocols so as to complete the protocol headers; and causing the network interface device to transmit the completed message over the network.

Abstract: Roughly described, a network interface device receiving data packets from a computing device for transmission onto a network, the data packets having a certain characteristic, transmits the packet only if the sending queue has authority to send packets having that characteristic. The data packet characteristics can include transport protocol number, source and destination port numbers, source and destination IP addresses, for example. Authorizations can be programmed into the NIC by a kernel routine upon establishment of the transmit queue, based on the privilege level of the process for which the queue is being established. In this way, a user process can use an untrusted user-level protocol stack to initiate data transmission onto the network, while the NIC protects the remainder of the system or network from certain kinds of compromise.

Abstract: A method and data processing system are provided. The data processing system comprises an application associated with a plurality of sockets and a sub-system for making data available to the application via the plurality of sockets. The sub-system is configured to provide in response to a request from the application: an indication of events that have occurred on one or more of the plurality of sockets; and an indication of an order in which the events should be processed.

Abstract: Data is received at a buffer used by a protocol processing stack which protocol processes the received data. The received data is made available to, for example, an application, before the protocol processing of the data is complete. If the protocol processing is successful the data made available to the application is committed.
