Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers

"OK Labs announced the availability of a verified, "bug-free secure microkernel" version of its Linux-compatible OKL4 hypervisor. Currently downloadable free for non-commercial evaluation on embedded ARM11 or x86 platforms, the "OKL4 Verified" microkernel is designed for business-critical and mission-critical applications in mobile/wireless devices, says the company.

"In August 2009, OK Labs (Open Kernel Labs) announced the completion of a "sel4" research project, intended to provide formal mathematical proof of the correctness of the microkernel used in the firm's Linux-ready OKL4 hypervisor. The research was conducted with NICTA (National Information and Communications Technology Australia), OK Labs' incubator and investor, as well as researchers from the University of New South Wales (UNSW) in Australia.

"NICTA's verified code base, now called OKL4 Verified, was derived from the same open source L4 project that spawned OKL4, says OK Labs. The verification process used with OKL4 Verified eliminates a wide range of exploitable errors in the kernel, says the company. These are said to include design flaws and code-based errors like buffer overflows, null pointer dereference, and other pointer errors, memory leaks, and arithmetic overflows and exceptions."
