A Ballista Retrospective
Software Robustness Testing A Ballista Retrospective Phil Koopman [email protected] http://ballista.org With contributions from: Dan Siewiorek, Kobey DeVale John DeVale, Kim Fernsler, Dave Guttendorf, Nathan Kropp, Jiantao Pan, Charles Shelton, Ying Shi Institute for Complex Engineered Systems Overview Introduction • APIs aren’t robust (and people act as if they don’t want them to be robust!) Top 4 Reasons people give for ignoring robustness improvement • “My API is already robust, especially for easy problems” (it’s probably not) • “Robustness is impractical” (it is practical) • “Robust code will be too slow” (it need not be) • “We already know how to do it, thank you very much” (perhaps they don’t) Conclusions • The big future problem for “near-stationary” robustness isn’t technology -- it is awareness & training 2 Ballista Software Testing Overview SPECIFIED INPUT RESPONSE BEHAVIOR SPACE SPACE ROBUST SHOULD VAL I D OPERATION WORK INPUTS MO DULE REPRODUCIBLE UNDEFINED UNDER FAILURE TEST SHOULD INVALID INPUTS UNREPRODUCIBLE RETURN FAILURE ERROR Abstracts testing to the API/Data type level • Most test cases are exceptional • Test cases based on best-practice SW testing methodology 3 Ballista: Test Generation (fine grain testing) Tests developed per data type/subtype; scalable via composition 4 Initial Results: Most APIs Weren’t Robust Unix & Windows systems had poor robustness scores: • 24% to 48% of intentionally exceptional Unix tests yielded non-robust results • Found simple “system killer” programs in Unix, Win 95/98/ME, and WinCE -

SCO Vs. IBM: Clarity As Push Approaches Shove
Managing L'unix Paul Murphy March 12th, 2007 SCO vs. IBM: clarity as push approaches shove Posted by Paul Murphy @ 12:15 am Just recently groklaw published both IBM's motion for summary judgement on SCO's contractual claims and SCO's rebuttal argument. The judge could rule on those today or later or this week, but the outcome is less interesting than the documents themselves because here, for the first time, both SCO and IBM state their cases clearly and relatively simply. As the motions make clear everything ultimately comes down to one issue: did IBM breach contracts now held by SCO? For a judge to grant a motion for summary judgement, however, the judge has to agree that the facts are undisputed, and since they're not my belief is that IBM's lawyers had to know that the only motion that counts, the one on contractual issues, would not succeed. The key question, therefore, is why they decided to waste the court's time with it - and my guess, because as regular readers known my belief is that SCO has a strong case, is first that they're trying to use IBM's financial strength to bankrupt SCO, and, secondly, that they're trying to establish a fundamental misrepresentation of the key issues as fact. Here's part of the critical text, from the SCO side: First, IBM argues briefly otherwise, but the plain language of the standard AT&T UNIX license agreement required the licensee to hold in confidence all parts of the modifications and derivative works the licensee developed based on the licensed UNIX software product. -
Understanding the Linux Kernel, 3Rd Edition by Daniel P
1 Understanding the Linux Kernel, 3rd Edition By Daniel P. Bovet, Marco Cesati ............................................... Publisher: O'Reilly Pub Date: November 2005 ISBN: 0-596-00565-2 Pages: 942 Table of Contents | Index In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does. This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics: • Memory management, including file buffering, process swapping, and Direct memory Access (DMA) • The Virtual Filesystem layer and the Second and Third Extended Filesystems • Process creation and scheduling • Signals, interrupts, and the essential interfaces to device drivers • Timing • Synchronization within the kernel • Interprocess Communication (IPC) • Program execution Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. -

Initially targeting netbooks, its main selling points are speed, simplicity and security — which kind of implies that the current No.1 OS doesn't deliver in these areas!
