摘要： An apparatus and method for improving the efficiency with which speculative critical sections are executed within a transactional memory architecture. For example, a method in accordance with one embodiment comprises: waiting to execute a speculative critical section of program code until a lock is freed by a current transaction; responsively executing the speculative critical section to completion upon detecting that the lock has been freed, regardless of whether the lock is held by another transaction during the execution of the speculative critical section; once execution of the speculative critical section is complete, determining whether the lock is taken; and if the lock is not taken, then committing the speculative critical section and, if the lock is taken, then aborting the speculative critical section.

摘要： A processing device implementing unbounded transactional memory with forward progress guarantees using a hardware global lock is disclosed. A processing device of the disclosure includes a hardware transactional memory (HTM) hardware contention manager to cause a bounded transaction to be translated to an unbounded transaction, the unbounded transaction to acquire a global hardware lock for the unbounded transaction, the global hardware lock read by bounded transactions that abort when the global hardware lock is taken. The processing device further includes an execution unit communicably coupled to the HTM hardware contention manager to execute instructions of the unbounded transaction without speculation, the unbounded transaction to release the global hardware lock upon completion of execution of the instructions.

摘要： Methods, systems, and computer programs are presented for detecting the root cause in use-after-free (UAF) memory corruption errors. A method includes an operation for tracking access to memory by a program to detect access to memory not allocated by the program. The method further includes operations for tracking allocations and deallocations of memory by the program, and for storing, in response to detecting a deallocation of memory by the program, at least part of a state of a program stack at a time of the deallocation of memory. Further, the method includes an operation for detecting, after the deallocation, access by the program to the memory associated with the deallocation of memory. In response to the detecting, the state of the program stack is saved in permanent storage at the time of the deallocation.

摘要： Technologies for identification of a potential root cause of a use-after-free memory corruption bug of a program include a computing device to replay execution of the execution of the program based on an execution log of the program. The execution log comprises an ordered set of executed instructions of the program that resulted in the use-after-free memory corruption bug. The computing device compares a use-after-free memory address access of the program to a memory address associated with an occurrence of the use-after-free memory corruption bug in response to detecting the use-after-free memory address access and records the use-after-free memory address access of the program as a candidate for a root cause of the use-after-free memory corruption bug to a candidate list in response to detecting a match between the use-after-free memory address access of the program and the memory address associated with the occurrence of the use-after-free memory corruption bug.

摘要： One or more embodiments may provide a method for performing a replay. The method includes initiating execution of a program, the program having a plurality of sets of instructions, and each set of instructions has a number of chunks of instructions. The method also includes intercepting, by a virtual machine unit executing on a processor, an instruction of a chunk of the number of chunks before execution. The method further includes determining, by a replay module executing on the processor, whether the chunk is an active chunk, and responsive to the chunk being the active chunk, executing the instruction.

摘要： A processor is described comprising memory access conflict detection circuitry to identify a conflict pertaining to a transaction being executed by a thread that believes it has locked information within a memory. The processor also includes logging circuitry to construct and report out a packet if the memory access conflict detection circuitry identifies a conflict that causes the transaction to be aborted.
