MECHANISM FOR INTERPOSING ON OPERATING SYSTEM CALLS |
摘要 |
A method for interposing on operating system calls in a host is provided. The method includes patching an operating system kernel function, the patching comprising adding a first pointer that invokes an agent function, the patching performed by an agent. The method includes executing the agent function, responsive to a system call stub calling the operating system kernel function, which invokes the agent function via the first pointer, wherein at least one action of the method is performed by a processor of a host having an operating system. |

1. A method for interposing on operating system calls in a host, comprising:
patching an operating system kernel function that is in a portion of memory distinct from a system call vector table, the patching comprising overwriting a portion of the operating system kernel function in the portion of the memory to add a first pointer that invokes an agent function, the patching performed by an agent without the agent patching the system call vector table; and executing the agent function, responsive to a system call stub calling the operating system kernel function, which invokes the agent function via the first pointer, wherein at least one action of the method is performed by a processor of a host having an operating system. |
