FreeBSD Quarterly Report

This report will be covering FreeBSD related projects between April and June, and covers a diverse set of topics ranging from kernel updates over userland and ports, as well to third-party work.
Some highlights picked with the roll of a d100 include, but are not limited to, the ability to forcibly unmounting UFS when the underlying media becomes inaccessible, added preliminary support for Bluetooth Low Energy, a introduction to the FreeBSD Office Hours, and a repository of software collections called potluck to be installed with the pot utility, as well as many many more things.
As a little treat, readers can also get a rare report from the quarterly team.
Finally, on behalf of the quarterly team, I would like to extend my deepest appreciation and thank you to salvadore@, who decided to take down his shingle. His contributions not just the quarterly reports themselves, but also the surrounding tooling to many-fold ease the work, are immeasurable.

Traditional Unix Toolchains

Older Unix systems tend to be fairly uniform in how they handle the so-called 'toolchain' for creating binaries. This blog will give a quick overview of the toolchain pipeline for Unix systems that follow the V7 tradition (which evolved along with Unix, a topic for a separate blog maybe).
Unix is a pipeline based system, either physically or logically. One program takes input, process the data and produces output. The input and output have some interface they obey, usually text-based. The Unix toolchain is no different.

Bastille Day 2020 : v0.7 released

This release matures the project from 0.6.x -> 0.7.x. Continued testing and bug fixes are proving Bastille capable for a range of use-cases. New (experimental) features are examples of innovation from community contribution and feedback. Thank you.

FreeBSD third quarterly status report for 2019

This quarter the reports team has been more active than usual thanks to a better organization: calls for reports and reminders have been sent regularly, reports have been reviewed and merged quickly (I would like to thank debdrup@ in particular for his reviewing work).

Efficiency could still be improved with the help of our community. In particular, the quarterly team has found that many reports have arrived in the last days before the deadline or even after. I would like to invite the community to follow the guidelines below that can help us sending out the reports sooner.

Starting from next quarter, all quarterly status reports will be prepared the last month of the quarter itself, instead of the first month after the quarter's end. This means that deadlines for submitting reports will be the 1st of January, April, July and October.

Next quarter will then be a short one, covering the months of November and December only and the report will probably be out in mid January.

OpenBSD on Sparc64

OpenBSD, huh? Yes, I usually write about FreeBSD and that’s in fact what I tried installing on the machine first. But I ran into problems with it very early on (never even reached single user mode) and put it aside for later. Since I powered up the SunFire again last month, I needed an OS now and chose OpenBSD for the simple reason that I have it available.

First I wanted to call this article simply “OpenBSD on SPARC” – but that would have been misleading since OpenBSD used to support 32-bit SPARC processors, too. The platform was just put to rest after the 5.9 release.

Version 6.0 was the last release of OpenBSD that came on CD-ROM. When I bought it, I thought that I’d never use the SPARC CD. But here was the chance! While it is an obsolete release, it comes with the cryptographic signatures to verify the next release. So the plan is to start at 6.0 as I can trust the original CDs and then update to the latest release. This will also be an opportunity to recap on some of the things that changed over the various versions.

News Roundup

ZoL repo move to OpenZFS

Because it will contain the ZFS source code for both Linux and FreeBSD, we will rename the "ZFSonLinux" code repository to "OpenZFS". Specifically, the repo at http://github.com/ZFSonLinux/zfs will be moved to the OpenZFS organization, at http://github.com/OpenZFS/zfs.

The next major release of ZFS for Linux and FreeBSD will be "OpenZFS 2.0", and is expected to ship in 2020.

Mcclure111 Sun Thread

A long time ago— like 15 years ago— I worked at Sun Microsystems. The company was nearly dead at the time (it died a couple years later) because they didn't make anything that anyone wanted to buy anymore. So they had a lot of strange ideas about how they'd make their comeback.

GEOM NOP

Sometimes while testing file systems or applications you want to simulate some errors on the disk level. The first time I heard about this need was from Baptiste Daroussin during his presentation at AsiaBSDCon 2016. He mentioned how they had built a test lab with it. The same need was recently discussed during the PGCon 2019, to test a PostgreSQL instance. If you are FreeBSD user, I have great news for you: there is a GEOM provider which allows you to simulate a failing device.

GNOP allows us to configure transparent providers from existing ones. The first interesting option of it is that we can slice the device into smaller pieces, thanks to the ‘offset option’ and ‘stripsesize’. This allows us to observe how the data on the disk is changing. Let’s assume that we want to observe the changes in the GPT table when the GPT flags are added or removed (for example the bootme flags which are described here). We can use dd every time and analyze it using absolute values from the disks.

Keeping NetBSD up-to-date with pkg_comp 2.0

This is a tutorial to guide you through the shiny new pkg_comp 2.0 on NetBSD.

Goals: to use pkg_comp 2.0 to build a binary repository of all the packages you are interested in; to keep the repository fresh on a daily basis; and to use that repository with pkgin to maintain your NetBSD system up-to-date and secure.

This tutorial is specifically targeted at NetBSD but should work on other platforms with some small changes. Expect, at the very least, a macOS-specific tutorial as soon as I create a pkg_comp standalone installer for that platform.
