Abstract: Techniques are disclosed for providing thread specific protection levels in a multithreaded processing environment. An associated method includes generating a group of threads in a process, one of the group of threads opening a thread entity, and that one of the group of threads specifying one or more levels of access to the thread entity for the other threads. In one embodiment, when a first of the threads attempts to perform a specified operation on the thread entity, the method of this invention determines whether that first thread is the one of the group of threads that opened the thread entity. When the first thread is not that one of the group of threads, the first thread is allowed to perform the specified operation if and only if such operation is permitted by the specified one or more levels of access.

In one embodiment, it is determined, at the network device, to create a network socket for an application of the network device to initiate a network connection for the application. Socket aggregation parameters are determined for the network socket associated with the application. The network socket is defined based, at least in part, on the socket aggregation parameters. A plurality of packets received from the application associated with the network socket are aggregated. It is determined, based on said aggregating the plurality of packets, whether at least one aggregation limit associated with the socket aggregation parameters is reached. An aggregate packet is provided to a network adapter of the network device to perform segmentation offload in response to said determining that at least one aggregation limit associated with the socket aggregation parameters is reached.

Abstract: Provided is reporting session information for a session upstream from a server. A data processing system receives a session handshake from a first client for a session between the server and the first client. The system receives a session-descriptor for a session between a second client and the first client before handling a nested session. The system determines whether a user has made an upstream session request. The system obtains session data from an upstream data structure, responsive to a determination that the user has made an upstream session request. The system renders the session data based on the upstream session request.

Abstract: A method, system and computer program product for transferring data between two applications over a local network connection. The invention establishes a socket connection between the applications and transfers data through the socket connection using a pseudo socket layer interface when the two endpoints of the socket connection are on the same host. Socket application program interface comprises socket buffers for sending and receiving data. A connecting application identifies and establishes a connection with a listening socket, and places data directly in the socket receive buffer of the receiving socket. If the other end of the socket connection is on a remote host, then data is transferred using underlying network facilities.

Abstract: In a computer system having memory, at least one processor and a physical input-output adapter, the at least one processor generates logical partitions, including local logical partitions and an input-output logical partition. The logical partitions have respective local virtual adapters. The input-output logical partition has a shared virtual adapter configured to communicate with the physical input-output adapter, such that a plurality of the local logical partitions share the physical input-output adapter via the shared virtual adapter. The at least one processor provides communication for ones of the local virtual adapters of the local logical partitions directly with the physical input-output adapter by a hypervisor.

Abstract: An embodiment allows an application to use a unique feature of an operating system residing on a LPAR different than its own. If the application makes a request for a feature not available in the operating system that it runs on, a transporter module can check its records to verify if such a feature exists on another operating system in a different LPAR. If it does exist, the transporter communicates to a facilitator of the operating system on the different LPAR though a hypervisor. The facilitator provides the unique feature to the transporter, who then forwards it to the application in need.
