Abstract
Official abstract text for this publication.
Systems and methods are provided for regular expression support in instrumentation languages using kernel-mode executable code. An example system includes a translator module that receives an input source code including a regular expression in a first source code language, wherein the translator module further determines a matching function in kernel-mode code language corresponding to the regular expression, and wherein the matching function corresponds to deterministic finite automaton. The system further includes a kernel module that processes at least one string using the matching function, wherein the matching function simulates state transitions of the deterministic finite automaton using the at least one string.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for providing regular expression support using kernel-mode code language matching functions, the system comprising: at least one hardware processor coupled to a non-transitory memory and configured to cause the system to execute: a translator module that receives a probe script comprising an input source code of an event occurring in a host machine operating system and compiles the probe script written in a scripting language comprising SystemTap,…
