  • Morpho-Syntactic Interactions Between V and C in Romance1
    Dialectologia. Special issue, V (2015), 293-319. ISSN: 2013-2247 Received 7 August 2015. Accepted 26 September 2015. MORPHO-SYNTACTIC INTERACTIONS BETWEEN V AND C IN ROMANCE1 Ángel J. GALLEGO Universitat Autònoma de Barcelona [email protected] Abstract This paper discusses a series of morpho-syntactic (a)symmetries that emerge in the vP and CP levels of different Romance languages. The (a)symmetries considered indicate a P or D oriented nature for specific functional heads placed in the vP and CP domains, an idea that has been at the forefront of micro-parametric studies ever since the 80s (cf. Kayne 1984, 2000; Uriagereka 1995). The consequences of this investigation for the status of parameter theory are further considered (cf. Chomsky 1981; Baker 2001; Biberauer 2008; Kayne 2000; Picallo 2014) and the study of the lexicon, arguably the main locus of linguistic variation (cf.

  • Porting the QEMU Virtualization Software to MINIX 3
    Porting the QEMU virtualization software to MINIX 3 Master's thesis in Computer Science Erik van der Kouwe Student number 1397273 [email protected] Vrije Universiteit Amsterdam Faculty of Sciences Department of Mathematics and Computer Science Supervised by dr. Andrew S. Tanenbaum Second reader: dr. Herbert Bos 12 August 2009 Abstract The MINIX 3 operating system aims to make computers more reliable and more secure by keeping privileged code small and simple. Unfortunately, at the moment only few major programs have been ported to MINIX. In particular, no virtualization software is available. By isolating software environments from each other, virtualization aids in software development and provides an additional way to achieve reliability and security. It is unclear whether virtualization software can run efficiently within the constraints of MINIX' microkernel design. To determine whether MINIX is capable of running virtualization software, I have ported QEMU to it. QEMU provides full system virtualization, aiming in particular at portability and speed. I find that QEMU can be ported to MINIX, but that this requires a number of changes to be made to both programs. Allowing QEMU to run mainly involves adding standardized POSIX functions that were previously missing in MINIX. These additions do not conflict with MINIX' design principles and their availability makes porting other software easier. A list of recommendations is provided that could further simplify porting software to MINIX. Besides just porting QEMU, I also investigate what performance bottlenecks it experiences on MINIX. Several areas are found where MINIX does not perform as well as Linux. The causes for these differences are investigated.

  • Can Microkernels Mitigate Microarchitectural Attacks?⋆
    Can Microkernels Mitigate Microarchitectural Attacks?? Gunnar Grimsdal1, Patrik Lundgren2, Christian Vestlund3, Felipe Boeira1, and Mikael Asplund1[0000−0003−1916−3398] 1 Department of Computer and Information Science, Link¨oping University, Sweden ffelipe.boeira,[email protected] 2 Westermo Network Technologies [email protected] 3 Sectra AB, Link¨oping,Sweden Abstract. Microarchitectural attacks such as Meltdown and Spectre have attracted much attention recently. In this paper we study how effec- tive these attacks are on the Genode microkernel framework using three different kernels, Okl4, Nova, and Linux. We try to answer the question whether the strict process separation provided by Genode combined with security-oriented kernels such as Okl4 and Nova can mitigate microar- chitectural attacks. We evaluate the attack effectiveness by measuring the throughput of data transfer that violates the security properties of the system. Our results show that the underlying side-channel attack Flush+Reload used in both Meltdown and Spectre, is effective on all in- vestigated platforms. We were also able to achieve high throughput using the Spectre attack, but we were not able to show any effective Meltdown attack on Okl4 or Nova. Keywords: Genode, Meltdown, Spectre, Flush+Reload, Okl4, Nova 1 Introduction It used to be the case that general-purpose operating systems were mostly found in desktop computers and servers. However, as IoT devices are becoming in- creasingly more sophisticated, they tend more and more to require a powerful operating system such as Linux, since otherwise all basic services must be im- plemented and maintained by the device developers. At the same time, security has become a prime concern both in IoT and in the cloud domain.

Among the various possibilities, the ERIKA Enterprise RTOS (Real-Time Operating System) and Linux with preemption patches have been selected. A description of the porting effort on the reference architecture has also been provided. 7.1 Introduction In the past, OSs for high-performance computing (HPC) were based on custom-tailored solutions to fully exploit all performance opportunities of supercomputers. Nowadays, instead, HPC systems are being moved away from in-house OSs to more generic OS solutions like Linux. Such a trend can be observed in the TOP500 list [1] that includes the 500 most powerful supercomputers in the world, in which Linux dominates the competition. In fact, in around 20 years, Linux has been capable of conquering all the TOP500 list from scratch (for the first time in November 2017). Each manufacturer, however, still implements specific changes to the Linux OS to better exploit specific computer hardware features. This is especially true in the case of computing nodes in which lightweight kernels are used to speed up the computation. 173 174 Embedded Operating Systems Figure 7.1 Number of Linux-based supercomputers in the TOP500 list.

  • Advanced Development of Certified OS Kernels Prof
    Advanced Development of Certified OS Kernels Zhong Shao (PI) and Bryan Ford (Co-PI) Department of Computer Science Yale University P.O.Box 208285 New Haven, CT 06520-8285, USA {zhong.shao,bryan.ford}yale.edu July 15, 2010 1 Innovative Claims Operating System (OS) kernels form the bedrock of all system software—they can have the greatest impact on the resilience, extensibility, and security of today’s computing hosts. A single kernel bug can easily wreck the entire system’s integrity and protection. We propose to apply new advances in certified software [86] to the development of a novel OS kernel. Our certified kernel will offer safe and application-specific extensibility [8], provable security properties with information flow control, and accountability and recovery from hardware or application failures. Our certified kernel builds on proof-carrying code concepts [74], where a binary executable includes a rigorous machine-checkable proof that the software is free of bugs with respect to spe- cific requirements. Unlike traditional verification systems, our certified software approach uses an expressive general-purpose meta-logic and machine-checkable proofs to support modular reason- ing about sophisticated invariants. The rich meta-logic enables us to verify all kinds of low-level assembly and C code [10,28,31,44,68,77,98] and to establish dependability claims ranging from simple safety properties to advanced security, correctness, and liveness properties. We advocate a modular certification framework for kernel components, which mirrors and enhances the modularity of the kernel itself. Using this framework, we aim to create not just a “one-off” lump of verified kernel code, but a statically and dynamically extensible kernel that can be incrementally built and extended with individual certified modules, each of which will provably preserve the kernel’s overall safety and security properties.

  • A Broad Market Approach to Antitrust Product Market Definition in Innovative Industries
    A Broad Market Approach to Antitrust Product Market Definition in Innovative Industries Andrew C. Hruska Detecting market power is crucial to antitrust enforcement, and agencies discern market power by examining concentration in a defined market. This Note argues that the current restrictive approach to market definition leads to overenforcement because agencies fail to account for the full range of restraints on market power. This problem can lead to particularly skewed market defini- tions in the context of innovation and cooperation among multiproduct firms. Innovation creates uncertainties about market structure and the course of development. Multi-product firms use innovative technologies as part of a larger mix of products, many of which are commoditized and interchangeable. A broader market definition approach would alleviate the problem of overenforce- ment by including the spectrum of partial substitutes and emerging replacements that the "smallest market" approach can ignore. An example of this definition problem arose with the joint venture between International Business Machines Corporation ("IBM") and Apple Computer Corporation ("Apple") to produce a new type of computer software. Announced in the summer of 1991, this joint venture, called Taligent, and four others between IBM and Apple collectively signalled a dramatic realignment of forces in the computer industry.' Taligent eventually received Federal Trade Com- mission (FTC) approval, but only after an investigation lasting several months.' Although Taligent survived its antitrust examination, similar ventures in the high-technology sector might well fail the tests of market concentration under the current guidelines for reviewing business combinations.3 The basic problem with the current Merger Guidelines is their method of defining the relevant product market.
