Rethinking OpenBSD security, FreeBSD 2020 Q1 status report, the notion of progress and user interfaces, Comments about Thomas E. Dickey on NetBSD curses, making Unix a little more Plan9-like, Not-actually Linux distro review: FreeBSD, and more. Headlines Rethinking OpenBSD Security OpenBSD aims to be a secure operating system. In the past few months there were quite a few security errata, however. That’s not too unusual, but some of the recent ones were a bit special. One might even say bad. The OpenBSD approach to security has a few aspects, two of which might be avoiding errors and minimizing the risk of mistakes. Other people have other ideas about how to build secure systems. I think it’s worth examining whether the OpenBSD approach works, or if this is evidence that it’s doomed to failure. I picked a few errata, not all of them, that were interesting and happened to suit my narrative. FreeBSD 2020 Q1 Quarterly report Welcome, to the quarterly reports, of the future! Well, at least the first quarterly report from 2020. The new timeline, mentioned in the last few reports, still holds, which brings us to this report, which covers the period of January 2020 - March 2020. News Roundup The Notion of Progress and User Interfaces One trait of modern Western culture is the notion of progress. A view claiming, at large, everything is getting better and better. How should we think about progress? Both in general and regarding technology? Thomas E. Dickey on NetBSD curses I was recently pointed at a web page on Thomas E. Dickeys site talking about NetBSD curses. It seems initially that the page was intended to be a pointer to some differences between ncurses and NetBSD curses and does appear to start off in this vein but it seems that the author has lost the plot as the document evolved and the tail end of it seems to be devolving into some sort of slanging match. I don't want to go through Mr. Dickey's document point by point, that would be tedious but I would like to pick out some of the things that I believe to be the most egregious. Please note that even though I am a NetBSD developer, the opinions below are my own and not the NetBSD projects. Making Unix a little more Plan9-like I’m not really interested in defending anything. I tried out plan9port and liked it, but I have to live in Unix land. Here’s how I set that up. A Warning The suckless community, and some of the plan9 communities, are dominated by jackasses. I hope that’s strong enough wording to impress the severity. Don’t go into IRC for help. Stay off the suckless email list. The software is great, the people who write it are well-spoken and well-reasoned, but for some reason the fandom is horrible to everyone. Not-actually Linux distro review: FreeBSD 12.1-RELEASE This month's Linux distro review isn't of a Linux distribution at all—instead, we're taking a look at FreeBSD, the original gangster of free Unix-like operating systems. The first FreeBSD release was in 1993, but the operating system's roots go further back—considerably further back. FreeBSD started out in 1992 as a patch-release of Bill and Lynne Jolitz's 386BSD—but 386BSD itself came from the original Berkeley Software Distribution (BSD). BSD itself goes back to 1977—for reference, Linus Torvalds was only seven years old then. Before we get started, I'd like to acknowledge something up front—our distro reviews include the desktop experience, and that is very much not FreeBSD's strength. FreeBSD is far, far better suited to running as a headless server than as a desktop! We're going to get a full desktop running on it anyway, because according to Lee Hutchinson, I hate myself—and also because we can't imagine readers wouldn't care about it. FreeBSD does not provide a good desktop experience, to say the least. But if you're hankering for a BSD-based desktop, don't worry—we're already planning a followup review of GhostBSD, a desktop-focused BSD distribution.

We extend a very large thank you to Jupiter Broadcasting and Linux Academy for hosting us for so many years, and allowing us to bring you over 100 episodes without advertisements. LinuxAcademy is now under new leadership, and we understand that cutbacks needed to be made, and that BSD is not their core product. That does not mean your favourite BSD podcast is going away, we will continue and we expect things will not look much different. What does this mean for you, the listener? Not much will change, just make sure your subscription is via the RSS feed at BSDNow.tv rather than one of the Jupiter Broadcasting feeds. We will update you with more news as things settle out.

Tales from a core file, Lenovo X260 BIOS Update with OpenBSD, the problem of Unix iowait and multi-CPU machines, Hugo workflow using FreeBSD Jails, Caddy, Restic; extending NetBSD-7 branch support, a tale of two hypervisor bugs, and more. Headlines Tales From a Core File - Lessons from the Unix stdio ABI: 40 Years Later On the side, I’ve been wrapping up some improvements to the classic Unix stdio libraries in illumos. stdio contains the classic functions like fopen(), printf(), and the security nightmare gets(). While working on support for fmemopen() and friends I got to reacquaint myself with some of the joys of the stdio ABI and its history from 7th Edition Unix. With that in mind, let’s dive into this, history, and some mistakes not to repeat. While this is written from the perspective of the C programming language, aspects of it apply to many other languages. Update Lenovo X260 BIOS with OpenBSD My X260 only runs OpenBSD and has no CD driver. But I still need to upgrade its BIOS from time to time. And this is possible using the ISO BIOS image. First off all, you need to download the “BIOS Update (Bootable CD)” from the Lenovo Support Website. News Roundup The problem of Unix iowait and multi-CPU machines Various Unixes have had a 'iowait' statistic for a long time now (although I can't find a source for where it originated; it's not in 4.x BSD, so it may have come through System V and sar). The traditional and standard definition of iowait is that it's the amount of time the system was idle but had at least one process waiting on disk IO. Rather than count this time as 'idle' (as you would if you had a three-way division of CPU time between user, system, and idle), some Unixes evolved to count this as a new category, 'iowait'. My Latest Self Hosted Hugo Workflow using FreeBSD Jails, Caddy, Restic and More After hosting with Netlify for a few years, I decided to head back to self hosting. Theres a few reasons for that but the main reasoning was that I had more control over how things worked. In this post, i’ll show you my workflow for deploying my Hugo generated site (www.jaredwolff.com). Instead of using what most people would go for, i’ll be doing all of this using a FreeBSD Jails based server. Plus i’ll show you some tricks i’ve learned over the years on bulk image resizing and more. Let’s get to it. Extending support for the NetBSD-7 branch Typically, some time after releasing a new NetBSD major version (such as NetBSD 9.0), we will announce the end-of-life of the N-2 branch, in this case NetBSD-7. We've decided to hold off on doing that to ensure our users don't feel rushed to perform a major version update on any remote machines, possibly needing to reach the machine if anything goes wrong. Security fixes will still be made to the NetBSD-7 branch. We hope you're all safe. Stay home. Tale of two hypervisor bugs - Escaping from FreeBSD bhyve VM escape has become a popular topic of discussion over the last few years. A good amount of research on this topic has been published for various hypervisors like VMware, QEMU, VirtualBox, Xen and Hyper-V. Bhyve is a hypervisor for FreeBSD supporting hardware-assisted virtualization. This paper details the exploitation of two bugs in bhyve - FreeBSD-SA-16:32.bhyve (VGA emulation heap overflow) and CVE-2018-17160 (Firmware Configuration device bss buffer overflow) and some generic techniques which could be used for exploiting other bhyve bugs. Further, the paper also discusses sandbox escapes using PCI device passthrough, and Control-Flow Integrity bypasses in HardenedBSD 12-CURRENT Beastie Bits GhostBSD 20.02 Overview FuryBSD 12.1 Overview > Joe Maloney got in touch to say that the issues in the video and other ones found have since been fixed.
