  • Bundling Spatially Correlated Prefetches for Improved Main Memory Row Buffer Locality
    Bundling Spatially Correlated Prefetches for Improved Main Memory Row Buffer Locality by Patrick Judd A thesis submitted in conformity with the requirements for the degree of Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto © Copyright by Patrick Judd 2014 Bundling Spatially Correlated Prefetches for Improved Main Memory Row Buffer Locality Patrick Judd Masters of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2014 Abstract Row buffer locality is a consequence of programs ’ inherent spatial locality that the memory system can easily exploit for significant performance gains and power savings. However, as the number of cores on a chip increases, request streams become interleaved more frequently and row buffer locality is lost. Prefetching can help mitigate this effect, but more spatial locality remains to be recovered. In this thesis we propose Prefetch Bundling, a scheme which tags spatially correlated prefetches with information to allow the memory controller to prevent prefetches from becoming interleaved. We evaluate this scheme with a simple scheduling policy and show that it improves the row hit rate by 11%. Unfortunately, the simplicity of the scheduling policy does not translate these row hits to improved performance or power savings. However, future work may build on this framework and develop more balanced policies that leverage the row locality of Prefetch Bundling. ii Acknowledgments There are many people to thank as I reflect back on my Master’s degree. First and foremost I must thank my supervisor, Andreas Moshovos, for his support, confidence in my abilities, and most of all for his ability to keep me grounded during stressful and trying times.

  • On the Viability of Memory Forensics in Compromised Environments
    On the Viability of Memory Forensics in Compromised Environments Zur Praktikabilit¨atvon Hauptspeicherforensik in kompromittierten Umgebungen Der Technischen Fakult¨atder Friedrich-Alexander-Universit¨at Erlangen-N¨urnberg zur Erlangung des Grades DOKTOR-INGENIEUR vorgelegt von Johannes Stuettgen aus Herdecke Als Dissertation genehmigt von der Technischen Fakult¨atder Friedrich-Alexander-Universit¨at Erlangen-N¨urnberg Tag der m¨undlichen Pr¨ufung: 28.05.2015 Vorsitzende des Promotionsorgans: Prof. Dr.-Ing. habil. Marion Merklein Gutachter: Prof. Dr.-Ing. Felix Freiling Prof. Dr. Michael Meier Abstract Memory forensics has become a powerful tool for the detection and analysis of ma- licious software. It provides investigators with an impartial view of a system, expos- ing hidden processes, threads, and network connections, by acquiring and analyzing physical memory. Because malicious software must be at least partially resident in memory in order to execute, it cannot remove all its traces from RAM. However, the memory acquisition process is vulnerable to subversion in compromised envi- ronments. Malicious software can employ anti-forensic techniques to intercept the acquisition and filter memory contents while they are copied. In this thesis, we analyze 12 popular memory acquisition tools for Windows, Linux, and Mac OS X, and study their implementation in regard to how they enumerate and map memory. We find that all of the analyzed programs use the operating system to perform these tasks, and further illustrate this by implementing an open source memory acquisition framework for Mac OS X. In a survey of kernel rootkit techniques, that prevent or filter physical memory access, we show that all 12 tested programs are vulnerable to anti-forensics, because they rely on the operating system for critical functions.

  • Exploiting the DRAM Rowhammer Bug to Gain Kernel Privileges
    Exploiting the DRAM rowhammer bug to gain kernel privileges Mark Seaborn, sandbox builder and breaker with contributions by Thomas Dullien, reverse engineer 9th March 2015 This article was originally published on the Google Project Zero blog. Contents Overview Introduction to the rowhammer problem Refining the selection of addresses to hammer Using the physical address mapping Random address selection Selecting addresses using timing Double­sided hammering Exploiting rowhammer bit flips NaCl sandbox escape Kernel privilege escalation Break it down: exploit steps Exploiting write access to page tables Routes for causing row hammering Experimental results Testing your own machine Mitigations Targeted refreshes of adjacent rows BIOS updates and increasing refresh rates Monitoring for row hammering using perf counters On disclosures On exploitability of bugs On vulnerability of machines Conclusion Credits Overview “Rowhammer” is a problem with some recent DRAM devices in which repeatedly accessing a row of memory can cause bit flips in adjacent rows. We tested a selection of laptops and found that a subset of them exhibited the problem. We built two working privilege escalation exploits that use this effect. One exploit uses rowhammer­induced bit flips to gain kernel privileges on x86­64 Linux when run as an unprivileged userland process. When run on a machine vulnerable to the rowhammer problem, the process was able to induce bit flips in page table entries (PTEs). It was able to use this to gain write access to its own page table, and hence gain read­write access to all of physical memory. We don’t know for sure how many machines are vulnerable to this attack, or how many existing vulnerable machines are fixable.

  • ABSTRACT Exploiting Unused Storage Resources to Enhance
    ABSTRACT Exploiting Unused Storage Resources to Enhance Systems’ Energy Efficiency, Performance, and Fault-Tolerance by Hai Huang Chair: Kang G. Shin The invention of better fabrication materials and processes in solid-state devices has led to unprecedented technological breakthroughs in computer hardware. Today’s system software, however, often cannot take full advantage of the hardware’s rapidly improving capabilities, thus resulting in idling resources, e.g., unoccupied memory and disk space. To make hardware operate more efficiently and to reduce the amount of idle resources, this thesis proposes several techniques that can harness such resources to the benefit of users. Although there are many different types of hardware resources, this thesis focuses on the reclamation of idle resources in the storage hierarchy. First, we implemented a pure software technique to reduce the power dissipation of main memory. By aggregating un- mapped and unused memory pages and powering down unused memory ranks, a signifi- cant amount of energy can be saved with little or no performance degradation. Next, we explored several architectural-level solutions that can more aggressively reduce energy, but at the expense of performance. We also developed techniques to exploit unused disk capacity to improve disks’ perfor- mance and energy-efficiency. These techniques are realized in our implementation of the Free Space File System (FS2). Unlike traditional file systems where extra disk space is not used, FS2 actively makes use of it to hold replicas of temporally-related data blocks that were poorly placed by the underlying file system. Using contiguous regions of free disk space to place related data blocks closer to one another enables disk heads to work more efficiently.
