SCRIPTED MULTIPROCESS PROBING WITHOUT SYSTEM PRIVILEGE

摘要

A controller process loads a module based on a user-generated script into itself. The controller process also generates a shared memory mapping using offset pointers as opposed to absolute pointers. The controller process loads the module and the shared memory mapping into target processes indicated by the user-generated script in order to probe the target processes.

1. A method comprising:
receiving a script indicating one or more probe points in one or more target processes; generating a module based on the script; and executing a controller process in user space to
generate a shared memory mapping comprising one or more offset pointers defining a shared memory space to be shared between the controller process and the one or more target processes, andload the module and the shared memory mapping into the one or more target processes.
