Secure the Clones * Static Enforcement of Policies for Secure Object Copying Thomas Jensen, Florent Kirchner, and David Pichardie INRIA Rennes – Bretagne Atlantique, France [email protected] Abstract. Exchanging mutable data objects with untrusted code is a delicate matter because of the risk of creating a data space that is accessible by an attacker. Consequently, secure programming guidelines for Java stress the importance of using defensive copying before accepting or handing out references to an inter- nal mutable object. However, implementation of a copy method (like clone()) is entirely left to the programmer. It may not provide a sufficiently deep copy of an object and is subject to overriding by a malicious sub-class. Currently no language-based mechanism supports secure object cloning.

  • Nested Class Modularity in Squeak/Smalltalk
    Springer, Nested Class Modularity in Squeak/Smalltalk Nested Class Modularity in Squeak/Smalltalk Modularität mit geschachtelten Klassen in Squeak/Smalltalk by Matthias Springer A thesis submitted to the Hasso Plattner Institute at the University of Potsdam, Germany in partial fulfillment of the requirements for the degree of Master of Science in ITSystems Engineering Supervisor Prof. Dr. Robert Hirschfeld Software Architecture Group Hasso Plattner Institute University of Potsdam, Germany August 17, 2015 Abstract We present the concept, the implementation, and an evaluation of Matriona, a module system for and written in Squeak/Smalltalk. Matriona is inspired by Newspeak and based on class nesting: classes are members of other classes, similarly to class instance variables. Top-level classes (modules) are globals and nested classes can be accessed using message sends to the corresponding enclosing class. Class nesting effec- tively establishes a global and hierarchical namespace, and allows for modular decomposition, resulting in better understandability, if applied properly. Classes can be parameterized, allowing for external configuration of classes, a form of dependency management. Furthermore, parameterized classes go hand in hand with mixin modularity. Mixins are a form of inter-class code reuse and based on single inheritance. We show how Matriona can be used to solve the problem of duplicate classes in different modules, to provide a versioning and dependency management mech- anism, and to improve understandability through hierarchical decomposition. v Zusammenfassung Diese Arbeit beschreibt das Konzept, die Implementierung und die Evaluierung von Matriona, einem Modulsystem für und entwickelt in Squeak/Smalltalk. Ma- triona ist an Newspeak angelehnt und basiert auf geschachtelten Klassen: Klassen, die, wie zum Beispiel auch klassenseitige Instanzvariablen, zu anderen Klassen gehören.

  • Lazy Object Copy As a Platform for Population-Based Probabilistic Programming
    Lazy object copy as a platform for population-based probabilistic programming Lawrence M. Murray Uber AI Abstract This work considers dynamic memory management for population-based probabilistic programs, such as those using particle methods for inference. Such programs exhibit a pattern of allocating, copying, potentially mutating, and deallocating collections of similar objects through successive generations. These objects may assemble data structures such as stacks, queues, lists, ragged arrays, and trees, which may be of random, and possibly unbounded, size. For the simple case of N particles, T generations, D objects, and resampling at each generation, dense representation requires O(DNT ) memory, while sparse representation requires only O(DT + DN log DN) memory, based on existing theoretical results. This work describes an object copy-on-write platform to automate this saving for the programmer. The core idea is formalized using labeled directed multigraphs, where vertices represent objects, edges the pointers between them, and labels the necessary bookkeeping. A specific labeling scheme is proposed for high performance under the motivating pattern. The platform is implemented for the Birch probabilistic programming language, using smart pointers, hash tables, and reference-counting garbage collection. It is tested empirically on a number of realistic probabilistic programs, and shown to significantly reduce memory use and execution time in a manner consistent with theoretical expectations. This enables copy-on-write for the imperative programmer, lazy deep copies for the object-oriented programmer, and in-place write optimizations for the functional programmer. 1 Introduction Probabilistic programming aims at better accommodating the workflow of probabilistic modeling and inference in general-purpose programming languages.

  • Concurrent Copying Garbage Collection with Hardware Transactional Memory
    Concurrent Copying Garbage Collection with Hardware Transactional Memory Zixian Cai 蔡子弦 A thesis submitted in partial fulfilment of the degree of Bachelor of Philosophy (Honours) at The Australian National University November 2020 © Zixian Cai 2020 Typeset in TeX Gyre Pagella, URW Classico, and DejaVu Sans Mono by XƎTEX and XƎLATEX. Except where otherwise indicated, this thesis is my own original work. Zixian Cai 12 November 2020 To 2020, what does not kill you makes you stronger. Acknowledgments First and foremost, I thank my shifu1, Steve Blackburn. When I asked you how to learn to do research, you said that it often takes the form of an apprenticeship. Indeed, you taught me the craft of research by example, demonstrating how to be a good teacher, a good researcher, and a good community leader. Apart from the vast technical ex- pertise, you have also been a constant source of advice, support, and encouragement throughout my undergraduate career. I could not ask for a better mentor. I thank Mike Bond from The Ohio State University, who co-supervises me. Meet- ings with you and Steve are always enjoyable for me. I am sorry for the meetings that went over time, often around the dinner time for you, lowering your glucose level. You help me turn complicated ideas into implementation with your experiences in hard- ware transactional memory. I am thankful for your patient guidance and inspiration. Many people have helped me with this thesis. I thank Adrian Herrera, Kunal Sa- reen, and Brenda Wang for subjecting themselves to the draft of this document, and providing valuable feedback.

  • ESUG 2012 Report
    CS21 and ESUG 23, Brescia, July 13th - 17th, 2015 1 CS21 and ESUG 23, Brescia, July 13th - 17th, 2015 This document contains my report of the ESUG conference in Brescia, July 13th - 17th, 2015 (and brief remarks on the Camp Smalltalk on the Sunday before it). As there were parallel tracks, I could not attend all talks. At the end, I also report a 2015 UK Smalltalk User Group meeting I attended. Style ‘I’ or ‘my’ refers to Niall Ross; speakers (other than myself) are referred to by name or in the third person. A question asked in or after a talk is prefixed by ‘Q.’ (sometimes I name the questioner; often I was too busy noting their question). A question not beginning with ‘Q.’ is a rhetorical question asked by the speaker (or is just my way of summarising their meaning). Author’s Disclaimer and Acknowledgements These reports give my personal view. No view of any other person or organisation with which I am connected is expressed or implied. The talk descriptions were typed while I was trying to keep up with and understand what the speakers were saying, so may contain errors of fact or clarity. I apologise for any inaccuracies, and to any participants whose names or affiliations I failed to note down. If anyone spots errors or omissions, email me and corrections may be made. My thanks to the conference organisers and the speakers whose work gave me something to report. My own talk is written up at much greater length than the others. Venue The accommodation was in old town of Brescia (called Brixia in Roman times).
