摘要： A system and method are disclosed for runtime probing of software. In accordance with one embodiment, a target method of a software application is modified to include a call to a first helper method and a call to a second helper method that occurs after the call to the first helper method. The first helper method collects runtime information, and at least one of the first helper method or the second helper method passes data comprising the runtime information to a native method that provides the data to a software tool (e.g., a performance monitoring tool, a debugger, etc.). The modified target method is then executed within a virtual machine.

摘要： Implementations for a secure remote kernel module signing are disclosed. In one example, the method includes receiving an indicator of a public key associated with a client computing device, determining that the public key associated with the client computing device is in common with a public key associated with a first server computing device, compiling the script, signing the compiled script with a private key that is associated with the public key that is in common with the client computing device and the first server computing device without generating a new private key, and sending the signed compiled script to the client computing device.

摘要： Providing dynamic instrumentation using domain-specific monitoring-language-to-kernel-bytecode compilation is disclosed. An instrumentation program file is converted by a compilation engine into multiple bytecode sections. A load and execute engine identifies which sections can be executed in kernel space and which can be executed in user space. The sections to be executed in kernel space are then loaded into a kernel space bytecode interpreter for execution, while the sections to be executed in user space are concurrently executed by a user space bytecode interpreter of the load and execute engine. In some examples, the load and execute engine may provide global variables that are accessible by both the kernel space and the user space, and that facilitate data exchange between the kernel space bytecode interpreter and the user space bytecode interpreter.

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.
