Abstract
A method for tracing function execution includes instantiating, by at least one hardware processor of a computing node, a user code runtime configured with access to an operating system (OS) kernel of the computing node. The user code runtime is configured with a first set of filtering policies associated with a first set of allowed system calls. The OS kernel is configured with a second set of filtering policies associated with a second set of allowed system calls. A system call initiated by the user code runtime is detected to violate one or both of the first set of allowed system calls and the second set of allowed system calls. A trace of the system call is initiated based on the detecting.
