GSoC Reports: Benchmarking NetBSD, third evaluation report


September 12, 2020 posted by Leonardo Taccari

This report was written by Apurva Nandan as part of Google Summer of Code 2020.

This blog post is in continuation of GSoC Reports: Benchmarking NetBSD, first evaluation report and GSoC Reports: Benchmarking NetBSD, second evaluation report blogs, and describes my progress in the final phase of GSoC 2020 under The NetBSD Foundation.

In the third phase, I upgraded to the latest stable version Phoronix Test Suite (PTS) 9.8.0 in pkgsrc-wip, resolved the TODOs and created patches for more test-profiles to fix their installation and runtime errors on NetBSD-current.

The GNU GDB Debugger and NetBSD (Part 4)


September 10, 2020 posted by Kamil Rytarowski

The NetBSD team of developers maintains two copies of GDB:
  • One in the base-system with a stack of local patches.
  • One in pkgsrc with mostly build fix patches.

The base-system version of GDB (GPLv3) still relies on a set of local patches. I set a goal to reduce the local patches to bare minimum, ideally reaching no local modifications at all.[Read More] [1 comment]

 

GSoC 2020: Report-2: Fuzzing the NetBSD Network Stack in a Rumpkernel Environment


August 30, 2020 posted by Kamil Rytarowski

This report was written by Nisarg S. Joshi as part of Google Summer of Code 2020.

The objective of this project is to fuzz the various protocols and layers of the network stack of NetBSD using rumpkernel. This project is being carried out as a part of GSoC 2020. This blog post is regarding the project, the concepts and tools involved, the objectives and the current progress and next steps.

GSoC Reports: Benchmarking NetBSD, second evaluation report


August 12, 2020 posted by Leonardo Taccari

This report was written by Apurva Nandan as part of Google Summer of Code 2020.

This blog post is in continuation of GSoC Reports: Benchmarking NetBSD, first evaluation report blog and describes my progress in the second phase of GSoC 2020 under The NetBSD Foundation.

In this phase, I worked on the automation of the regression suite made using Phoronix Test Suite (PTS) and its integration with Anita.

The automation framework consists of two components Phoromatic server, provided by Phoronix Test Suite in pkgsrc, and Anita, a Python tool for automating NetBSD installation.

GSoC Reports: Enhancing Syzkaller support for NetBSD, Part 2


August 05, 2020 posted by Kamil Rytarowski

This report was prepared by Ayushi Sharma as a part of Google Summer of Code 2020

As a part of Google summer code 2020, I have been working on Enhance the Syzkaller support for NetBSD. This post summarises the work done in the past month.

For work done in the first coding period, you can take a look at the previous post.

Automation for enhancement

With an aim of increasing the number of syscalls fuzzed, we have decided to automate the addition of descriptions for syscalls as well as ioctl device drivers in a customised way for NetBSD.

GSoC Reports: Benchmarking NetBSD, first evaluation report


July 16, 2020 posted by Leonardo Taccari

This report was written by Apurva Nandan as part of Google Summer of Code 2020.

My GSoC project under NetBSD involves developing an automated regression and performance test framework for NetBSD that offers reproducible benchmarking results with detailed history and logs across various hardware & architectures.

To achieve this performance testing framework, I am using the Phoronix Test Suite (PTS) which is an open-source, cross-platform automated testing/benchmarking software for Linux, Windows and BSD environments. It allows the creation of new tests using simple XML files and shell scripts and integrates with revision control systems for per-commit regression testing.

GSoC Reports: Extending the functionality of NetPGP, Part 1


July 13, 2020 posted by Kamil Rytarowski

This report was prepared by Jason High as a part of Google Summer of Code 2020

NetPGP is a library and suite of tools implementing OpenPGP under a BSD license. As part of Google Summer of Code 2020, we are working to extend its functionality and work towards greater parity with similar tools. During the first phase, we have made the following contributions

  1. Added the Blowfish block cipher
  2. ECDSA key creation
  3. ECDSA signature and verification
  4. Symmetric file encryption/decryption
  5. S2K Iterated+Salt for symmetric encryption

GSoC Reports: Curses Library Automated Testing, Part 1


July 13, 2020 posted by Kamil Rytarowski

This report was prepared by Naman Jain as a part of Google Summer of Code 2020

Introduction

My GSoC project under NetBSD involves the development of test framework of curses library. Automated Test Framework (ATF) was introduced in 2007 but ATF cannot be used directly for curses testing for several reasons most important of them being curses has functions which do timed reads/writes which is hard to do with just piping characters to test applications. Also, stdin is not a tty device and behaves differently and may affect the results. A lot of work regarding this has been done and we have a separate test framework in place for testing curses.

The aim of project is to build a robust test suite for the library and complete the SUSv2 specification. This includes writing tests for the remaining functions and enhancing the existing ones. Meanwhile, the support for complex character function has to be completed along with fixing some bugs, adding features and improving the test framework.
