The sandboxing system implemented in Google`s Chrome browser has undergone a major overhaul in development version 23.0.1255.0 with the introduction of a brand new sandbox on Linux and ChromeOS for renderers. The new sandbox uses a feature called Seccomp-BPF that gives the Linux kernel a higher degree of control in imposing restrictions to the application, as well as to evaluate system call numbers and their parameters. This approach will likely result not only in performance improvements, but will allow the kernel to detect logic traps such as code that makes it loop endlessly until it depletes the system`s resources.”]
