At this year’s AsiaBSDCon, I presented a talk about a SDN network emulator called Mininet, and my ongoing work to make it more portable. That presentation was focused on the OpenBSD version of the port, and I breezed past the detail that I also had a version or Mininet working on FreeBSD. Because I was given the opportunity, I’d like to share a bit about the FreeBSD version of Mininet. It will not only be about what Mininet is and why it might be interesting, but also a recounting of my experience as a user making a first-time attempt at porting an application to FreeBSD.
I had the opportunity to attend SCaLEx16 (Southern California Linux Expo) March 8-11, in Pasadena, California. Based on its name, one would think it was a Linux conference. While that may have been the focus in the beginning, today the conference is evolving into an open source conference with many other projects involved. If only they could remove the L from the name…
We are pleased to announce that the Oregon State University (OSU) Open Source Lab (OSL), which hosts infrastructure for over 160 different open source projects, has agreed to host some of our servers for FreeBSD development.
At the end of last year I mentioned the Syzkaller kernel system call fuzzer and the work done by one of the Foundation’s co-op students to integrate and automate its use in FreeBSD. As a brief refresher, Syzkaller is a coverage-guided system call fuzzer. It invokes syscalls with arbitrary and changing inputs, and is intended to use code coverage data to guide changes to system call inputs in order to access larger and larger portions of the kernel in the search for bugs.
We’re pleased to announce a new Iridium Level Donor: NetApp. Thank you for your ongoing support of open source and your commitment to FreeBSD.
The FreeBSD Foundation funded my attendance and part of my travel to APRICOT 2018 in Kathmandu, Nepal.
APRICOT is the largest annual internet community conference in the Asia-Pacific region. Nearly one thousand attendees show up for two weeks of workshops, tutorials and presentations. While the primary focus of the conference is on networking, the conference also attracts a sizable number of systems people. I also attended some of the APTLD conference which overlapped for a couple of days during the APRICOT workshop week. This was the first time I attended APRICOT.
Issues affecting most CPUs used in servers, desktops, laptops, and mobile devices are in the news. These hardware vulnerabilities, known by the code-names “Meltdown” and “Spectre”, allow malicious programs to read data to which they should not have access. This potentially includes credentials, cryptographic material, or other secrets.
