User action security auditing
In a storage area network (SAN), a SAN management application provides a security audit log of security sensitive user actions performed across the storage area network. In a SAN, multiple services operate to perform requested user actions. Configurations herein substantially overcome the shortcomings of conventional SAN security event logging by providing a comprehensive security audit mechanism operable to identify and record user actions. An event normalizer disposed in each of the services identifies requested user actions, creates a uniform user action object, and sends the user action object to a coalescer operable to receive user action objects from the plurality of services in the SAN. The user action object provides a generic template responsive to each of the event normalizers in the services. The event normalizers normalize event properties and attributes concerning a user action into the generic user action object, and employs preexisting conduits for gathering and recording events. |

Network attack detection using partial deterministic finite automaton pattern matching
This disclosure describes techniques for determining whether network traffic contains one or more computer security threats. In order to determine whether a symbol stream conforms to the symbol pattern, a security device stores a full deterministic finite automaton (fDFA) that accepts streams of symbols that conform to the symbol pattern. The security device also creates a partial deterministic finite automaton (pDFA) that includes nodes that correspond to the nodes in the fDFA that have the highest visitation levels. The security device processes each symbol in the symbol stream using the pDFA until a symbol causes the pDFA to transition to a failure node or to an accepting node. If the symbol causes the pDFA to transition to the failure node, the security device processes the symbol and subsequent symbols in the symbol stream using the fDFA. |

Placement driven routing
A method placing items routing wiring pursuant to integrated circuit specifications to create an integrated circuit design. Once the initially placed design is legalized, rather that just starting wiring routing, the method identifies books in the integrated circuit design which contain blocked items. The method allows the routing process to be paused temporarily, and for the items to be moved to a certain extent. This movement process is controlled (limited according to signal power output by the associated books) so that the timing of the integrated circuit design is not affected by any such “mid-routing” movement. If the books do not have any blocked items, the process continues to route wires between the items and the books. If at any point before or during the routing of the wires it is found that the books do have blocked items, the process pauses the routing of the wires and performs any number of different processes to solve the blocked item situation (unblock the blocked items). |

The present invention provides a solution that unifies independent data sources into a single data source by hiding one of the data sources in metadata. The non-hidden source, which can reference the hidden source, can be processed by a primary XML processing agent. This agent can initially ignore syntax and semantics of content associated with the hidden source, which is contained within the metadata. A secondary XML processing agent can transform the hidden source into a readable form, which is consumable by the primary processing agent. The primary XML processing agent can receive this readable form as a content stream. The primary XML processing agent can be unaware that the content stream originates from the unified source, which permits the unified source to represent multiple sources while preserving “rules” that typically prohibit multiple data types to be included in a single source. |

Method for decoding data in non-volatile storage using reliability metrics based on multiple reads
Data stored in non-volatile storage is decoded using iterative probabilistic decoding and multiple read operations to achieve greater reliability. An error correcting code such as a low density parity check code may be used. In one approach, initial reliability metrics, such as logarithmic likelihood ratios, are used in decoding read data of a set of non-volatile storage element. The decoding attempts to converge by adjusting the reliability metrics for bits in code words which represent the sensed state. If convergence does not occur, e.g., within a set time period, the state of the non-volatile storage element is sensed again, current values of the reliability metrics in the decoder are adjusted, and the decoding again attempts to converge. In another approach, the initial reliability metrics are based on multiple reads. Tables which store the reliability metrics and adjustments based on the sensed states can be prepared before decoding occurs. |

Sector-oriented hardware defect compression based on format information
A system and method identifies and masks physical sectors where the errors encountered during the defect scan exceed a predetermined level. This avoids the need to read and process all the data written to an individual sector during the initial defect scan. This method first writes a predetermined pattern such as a 2-T pattern to the magnetic media available for user data. This written pattern is then read. As the pattern is read, an error result increments or decrements a counter based on the error. The counter reaching a predetermined level signifies that there are too many errors in this physical sector. This sector may then be added to the primary defect list and masked out without reading the remaining written pattern within the sector. This will result significant time savings as physical sectors containing multiple errors are identified without process all the information written to the physical sector. The primary defect list is used during the low-level format to map logical locations to physical locations. |

A semi-static transaction may involve obtaining, possibly after incrementing, a reference version value against which to subsequently validate that memory locations, such as read-set locations, have not been modified concurrently with the semi-static transaction. The read-set locations may be validated while locks are held for the locations to be written (e.g., the write-set locations). After committing the modifications to the write-set locations and as part of releasing the locks, versioned write-locks associated with the write-set locations may be updated to reflect the previously obtained, or newly incremented, reference version value. |

Selectively monitoring loads to support transactional program execution
One embodiment of the present invention provides a system that selectively monitors load instructions to support transactional execution of a process, wherein changes made during the transactional execution are not committed to the architectural state of a processor until the transactional execution successfully completes. Upon encountering a load instruction during transactional execution of a block of instructions, the system determines whether the load instruction is a monitored load instruction or an unmonitored load instruction. If the load instruction is a monitored load instruction, the system performs the load operation, and load-marks a cache line associated with the load instruction to facilitate subsequent detection of an interfering data access to the cache line from another process. If the load instruction is an unmonitored load instruction, the system performs the load operation without load-marking the cache line. |

System and program product for validating remotely cached dynamic content web pages
Under the present invention, when a request for a web page is received from a client on a server, the web page is built and analyzed for cacheability. If the web page is cacheable, an entity tag is generated. The entity tag generally identifies the various sources of dynamic content in the web page, and includes cacheability flags and time values associated with the dependencies. The entity tag is sent to the client with the web page where it is stored in local cache memory. If a subsequent request for the same web page is issued from the client, the request is accompanied with the entity tag (e.g., in a header). The entity tag is decoded and analyzed by the server to determine whether the cached web page is still valid. |

Cache residence prediction
The present invention proposes a novel cache residence prediction mechanism that predicts whether requested data of a cache miss can be found in another cache. The memory controller can use the prediction result to determine if it should immediately initiate a memory access, or initiate no memory access until a cache snoop response shows that the requested data cannot be supplied by a cache.The cache residence prediction mechanism can be implemented at the cache side, the memory side, or both. A cache-side prediction mechanism can predict that data requested by a cache miss can be found in another cache if the cache miss address matches an address tag of a cache line in the requesting cache and the cache line is in an invalid state. A memory-side prediction mechanism can make effective prediction based on observed memory and cache operations that are recorded in a prediction table. |

Hardware arithmetic engine for lambda rule computations
A recursive lambda rule engine (114, 302) includes a first multiplier (204) that sequentially multiplies each of series of inputs by a nonlinearity determining parameter and supplies results to a second multiplier (214) that multiplies the output of the first multiplier (204) by a previous output of the engine (114, 302). A three input adder (220, 228) sequentially sums the output of the second multiplier (214), inputs from the series of inputs, and the previous output of the engine (114, 302). A shift register (244) is used to feedback the output of the engine (114, 302) to the three input adder (220, 228) and second multiplier (214). A MUX (234) is used to route an initial value through the shift register (244) for the first cycle of operation. |

Repetitive controller to compensate for odd harmonics
A repetitive controller scheme with negative feedback and feedforward introduces infinitely many poles on the imaginary axis located at the resonant peaks. The feedforward introduces zeros, which produce notches located in between two consecutive resonant peaks. The latter has the advantage of making the controllers more selective, in the sense that the original overlapping (appearing at the valleys) or interaction between consecutive resonant peaks is removed by the notches. This would allow, in principle, peaks of higher gains and slightly wider bandwidth, avoiding, at the same time, the excitation of harmonics located in between two consecutive peaks. A negative feedback compensator with feedforward is especially useful when only the compensation of odd harmonics is required, but not the even harmonics, like in many power electronic systems. In contrast, the positive feedback controller would try to reinject, and indeed amplify, any small noise, which has components on the even frequencies. The negative feedback repetitive controller includes a simple Low Pass Filter (LPF). This modification restricts the bandwidth of the controller, and at the same time reinforces the stability when the controller is inserted in a closed-loop system. |

Realtime-safe read copy update with lock-free readers
A technique for realtime-safe detection of a grace period for deferring the destruction of a shared data element until pre-existing references to the data element have been removed. A pair of counters is established for each of one or more processors. A global counter selector determines which counter of each per-processor counter pair is a current counter. When reading a shared data element at a processor, the processor's current counter is incremented. Following counter incrementation, the processor's counter pair is tested for reversal to ensure that the incremented counter is still the current counter. If a counter reversal has occurred, such that the incremented counter is no longer current, the processor's other counter is incremented. Following referencing of the shared data element, any counter that remains incremented is decremented. Following an update to the shared data element wherein a pre-update version of the element is maintained, the global counter selector is switched to establish a new current counter of each per-processor counter pair. The non-current counter of each per-processor counter pair is tested for zero. The shared data element's pre-update version is destroyed upon the non-current counter of each per-processor counter pair being zero. |

Signaling protocol registration load reduction
An intermediate device is described that reduces the number of signaling registration requests and responses flowing across a network. For example, a load reducing device intercepts the registration requests, filters a portion of the requests, and outputs autonomous response for each filtered registration request. The load reducing device forwards an unfiltered portion of the registration requests sufficient to maintain registration of the requesting device. The autonomous responses keep a logical pinhole in a firewall in an open state so that the registering device behind the firewall can receive session initiation invitations. At the same time, filtering the portion of the requests reduces the number of requests and responses that traverse any intermediate networks between the load reducing device and an intended recipient of the request. |

Technique for dynamically splitting MPLS TE-LSPs
A technique dynamically splits Traffic Engineering (TE) Label Switched Paths (LSPs) in a computer network. According to the novel technique, a head-end node may determine that a TE-LSP to a destination needs to be sized to a larger bandwidth (a “larger” TE-LSP) than currently available over a single path to the destination (e.g., a path that may also be required to meet other constraints, such as cost, delay, etc.). In response, the head-end node may dynamically “split” the larger TE-LSP, and create a first split TE-LSP over a best (e.g., shortest) available path (e.g., that meets other constraints). The first split TE-LSP may reserve a maximum available bandwidth for that best available path. The head-end node may then continue recursively creating subsequent split TE-LSPs for any remaining bandwidth of the larger TE-LSP over available paths until the larger TE-LSP may no longer be split (e.g., all bandwidth has been placed, configurable maximum number of splits reached, etc.). Notably, the split TE-LSPs may be “re-groomed” at a later time to recombine and reorganize the split TE-LSPs. |

For each BS, a diversity set is maintained for the sets of MS. Each BS determines possible interference at the MS based on the diversity set. A graph is constructed, in which nodes represent the sets of MS, mid each edge between a pair of nodes represents channel interference between the MS represented by the pair of nodes. A weight is assigned to each edge, which reflects interference between the two MSs connected by the edge. The interference graph is partitioned into non-overlapping clusters of nodes based on a structure of the interference graph, the potential interference, so that a sum of the weights of the edges between each cluster is maximized. Based upon the graph partitioning, the channel resources are allocated to the mobile stations in order to maximize the system capacity. |

A current passing through the micro machine device due to the application of the control voltage are detected with respect to positive and negative sides, and parameters related to a capacitance of the micro machine device are acquired with respect to the positive and negative sides on the basis of the detected current. The control voltage is controlled so that the parameters acquired with respect to the positive and negative sides accord with each other. Thus, variation of the capacitance between the positive side and the negative side can be suppressed in switching drive of a variable capacitance device. |
