Abstract: A topology discovery process is used to discover all of the links in an ad hoc network and thereby ascertain the topology of the entire network. One of the nodes of the network, referred to as the coordinator, receives the topology information which can then be used to, for example, distribute a routing table to each other node of the network. The process has a Diffusion phase in which a k-resilient mesh, k>1, is created by propagating a topology request message through the network. Through this process, the nodes obtain information from which they are able to discern their local neighbor information. In a subsequent, Gathering phase, the local neighbor information is reported upstream from a node to its parents in the mesh and thence to the parents' parents and so forth back to the coordinator. The robustness of the Diffusion phase is enhanced by allowing a node to have more than one parent as well as by a number of techniques, including use of a so-called diffusion acknowledgement message.

Abstract: The present embodiments provide methods for detecting errors and vulnerabilities in software without access to its source code. The method entails extracting functions from dynamically linked applications, determining error return codes and error numbers for the extracted functions, and forming a wrapper using the extracted functions. The wrapper is used to intercept some of the function calls, wherein the intercepted functions are manipulated to fail. The embodiments further relate to an article of manufacture to detect errors. The article of manufacture utilizes an extraction module to extract functions from dynamically linked applications, software to compile error return codes and error numbers for functions, and a wrapper module to form a wrapper with the extracted functions.

Abstract: Computer architecture and method splice a new TCP connection. A proxy group for the new TCP connection is determined and, at one of the proxies, the new TCP connection is accepted. At the one proxy, a client request is received from a client of the new TCP connection and an appropriate backend server to handle the client request is determined. At the one proxy, the client request is spliced and sent to the appropriate backend server. Splicing state information of the new TCP connection is sent from the one proxy to other proxies of the proxy group. Each subsequent TCP segment of the new TCP connection is spliced and sent to the appropriate backend server at any one proxy of the proxy group.

Abstract: A method includes a step of executing a software function using a set of test arguments and obtaining a result corresponding to each of the set of test arguments, each result indicating one of a set of robust and non-robust results, a subset of test arguments corresponding to robust results. The method further includes defining a set of arguments based on the results and the set of test arguments, the set of arguments including the subset of test arguments. Thereafter, arguments of subsequent calls to the software function may thereafter be examined to determine whether they fall within the set of arguments.

Abstract: A method and apparatus for detecting a heap smashing condition. A call to a library function, such as a request to write a data block to the heap section of a memory, is intercepted from a program being executed. In an embodiment, a fault-containment wrapper module determines whether performing the write request would smash the heap. If it would smash the heap, an error handling procedure is executed instead of writing the data block. If it would not smash the heap, the fault-containment wrapper module causes the data block to be written to the memory as requested.
