Controlling Script Execution - Mickaël Salaün, Microsoft
Linux can rely on several mechanisms to control executable code. However, scripts have always been a grey area because they are not directly executed by the kernel but by a user space interpreter. We propose a new way to control script execution, relying on the kernel to manage a global consistent execution policy. While it may be seen as a simple problem at first, we'll see the different use cases and challenges that led to the current implementation, going through the previous O_MAYEXEC open flag and the dedicated trusted_for syscall approaches.
