A 35 Year Old Bug in Patch

Larry Wall posted patch 1.3 to mod.sources on May 8, 1985. A number of versions followed over the years. It's been a faithful alley for a long, long time. I've never had a problem with patch until I embarked on the 2.11BSD restoration project. In going over the logs very carefully, I've discovered a bug that bites this effort twice. It's quite interesting to use 27 year old patches to find this bug while restoring a 29 year old OS...

Sandbox for FreeBSD

A sandbox is a software which artificially limits access to the specific resources on the target according to the assigned policy. The sandbox installs hooks to the kernel syscalls and other sub-systems in order to interrupt the events triggered by the application. From the application point of view, application working as usual, but when it wants to access, for instance, /dev/kmem the sandbox software decides against the assigned sandbox scheme whether to grant or deny access.
In our case, the sandbox is a kernel module which uses MAC (Mandatory Access Control) Framework developed by the TrustedBSD team. All necessary hooks were introduced to the FreeBSD kernel.

Changing from one dataset to another within a jail

ZFS has a the ability to share itself within a jail. That gives the jail some autonomy, and I like that.
I’ve written briefly about that, specifically for iocage. More recently, I started using a zfs snapshot for caching clearing.
The purpose of this post is to document the existing configuration of the production FreshPorts webserver and outline the plan on how to modify it for more zfs-snapshot-based cache clearing.

You don’t need tmux or screen for ZFS

Back in January I mentioned how to add redundancy to a ZFS pool by adding a mirrored drive. Someone with a private account on Twitter asked me why FreeBSD—and NetBSD!—doesn’t ship with a tmux or screen equivilent in base in order to daemonise the process and let them run in the background.
ZFS already does this for its internal commands.

HardenedBSD August 2020 Status Report and Call for Donations

This last month has largely been a quiet one. I've restarted work on porting five-year-old work from the Code Pointer Integrity (CPI) project into HardenedBSD. Chiefly, I've started forward-porting the libc and rtld bits from the CPI project and now need to look at llvm compiler/linker enhancements. We need to be able to apply SafeStack to shared objects, not just application binaries. This forward-porting work I'm doing is to support that effort.
The infrastructure has settled and is now churning normally and happily. We're still working out bandwidth issues. We hope to have a new fiber line ran by the end of September.
As part of this status report, I'm issuing a formal call for donations. I'm aiming for $4,000.00 USD for a newer self-hosted Gitea server. I hope to purchase the new server before the end of 2020.

Important parts of Unix's history happened before readline support was common

Unix and things that run on Unix have been around for a long time now. In particular, GNU Readline was first released in 1989 (as was Bash), which is long enough ago for it (or lookalikes) to become pretty much pervasive, especially in Unix shells. Today it's easy to think of readline support as something that's always been there. But of course this isn't the case. Unix in its modern form dates from V7 in 1979 and 4.2 BSD in 1983, so a lot of Unix was developed before readline and was to some degree shaped by the lack of it.

LibreSSL documentation status update

More than six years ago, LibreSSL was forked from OpenSSL, and almost two years ago, i explained the status of LibreSSL documentation during EuroBSDCon 2018 in Bucuresti. So it seems providing an update might be in order.
Note that this is not an update regarding LibreSSL status in general because i'm not the right person to talk about the big picture of working on the LibreSSL code, my work has been quite focussed on documentation. All the same, it is fair to say that even though the number of developers working on it is somewhat limited, the LibreSSL project is quite alive, typically having a release every few months. Progress continues being made with respect to porting and adding new functionality (for example regarding TLSv1.3, CMS, RSA-PSS, RSA-OAEP, GOST, SM3, SM4, XChaCha20 during the last two years), OpenSSL compatibility improvements (including providing additional OpenSSL-1.1 APIs), and lots of bug fixes and code cleanup.

FreeBSD on SPARC64 (is dead)

’m coming pretty late to the party, because SPARC64 support in FreeBSD is apparently doomed: After the POWER platform made the switch to a LLVM/Clang-based toolchain, SPARC64 is one of the last ones that still uses the ancient GCC 4.2-based toolchain that the project wants to finally get rid off (it has already happened as I was writing this – looks like the firm plan was not so firm after all, since they killed it off early). And compared to the other platforms it has seen not too much love in recent times… SPARC64 being a great platform, I’d be quite sad to see it go. But before that happens let’s see what the current status is and what would need to be done if it were to survive, shall we?

News Roundup

Bringing zpool checkpoints to a FreeBSD bootloader

Almost two years ago I wrote a blog post about checkpoints in ZFS. I didn’t hide that I was a big fan of them. That said, after those two years, I still feel that there are underappreciated features in the ZFS world, so I decided to do something about that.
Currently, one of the best practices for upgrading your operating system is to use boot environments. They are a great feature for managing multiple kernels and userlands. They are based on juggling which ZFS datasets are mounted. Each dataset has its own version of the system. Unfortunately, boot environments have their limitations. If we, for example, upgrade our ZFS pool, we may not be able to use older versions of the system anymore.
The big advantage of boot environments is that they have very good tools. Two main tools are beadm (which was created by vermaden) and bectl (which currently is in the FreeBSD base system). These tools allow us to create and manage boot environments.

FreeBSD USB Audio

I recently got a Behringer UMC22 sound card for video conferencing and DJing. This page documents what I’ve learned about using this sound card, and USB audio in general, on FreeBSD.
tl;dr: Everything works as long as the sound card follows the USB audio device class specification.

Kyua: An introduction for NetBSD users

Kyua's current goal is to reimplement only the ATF tools while maintaining backwards compatibility with the tests written with the ATF libraries (i.e. with the NetBSD test suite).
Because Kyua is a replacement of some ATF components, the end goal is to integrate Kyua into the NetBSD base system (just as ATF is) and remove the deprecated ATF components. Removing the deprecated components will allow us to make the above-mentioned improvements to Kyua, as well as many others, without having to deal with the obsolete ATF code base. Discussing how and when this transition might happen is out of the scope of this document at the moment.

Keeping backup ZFS on Linux kernel modules around

I'm a long term user of ZFS on Linux and over pretty much all of the time I've used it, I've built it from the latest development version. Generally this means I update my ZoL build at the same time as I update my Fedora kernel, since a ZoL update requires a kernel reboot anyway. This is a little bit daring, of course, although the ZoL development version has generally been quite solid (and this way I get the latest features and improvements long before I otherwise would).

Command-line Tools can be 235x Faster than your Hadoop Cluster

As I was browsing the web and catching up on some sites I visit periodically, I found a cool article from Tom Hayden about using Amazon Elastic Map Reduce (EMR) and mrjob in order to compute some statistics on win/loss ratios for chess games he downloaded from the millionbase archive, and generally have fun with EMR. Since the data volume was only about 1.75GB containing around 2 million chess games, I was skeptical of using Hadoop for the task, but I can understand his goal of learning and having fun with mrjob and EMR. Since the problem is basically just to look at the result lines of each file and aggregate the different results, it seems ideally suited to stream processing with shell commands. I tried this out, and for the same amount of data I was able to use my laptop to get the results in about 12 seconds (processing speed of about 270MB/sec), while the Hadoop processing took about 26 minutes (processing speed of about 1.14MB/sec).

FreeBSD Laptop Find Out Battery Life Status Command

I know how to find out battery life status using Linux operating system. How do I monitor battery status on a laptop running FreeBSD version 9.x/10.x/11.x/12.x?
You can use any one of the following commands to get battery status under FreeBSD laptop including remaining battery life and more.

FreeBSD Qt WebEngine GPU Acceleration

FreeBSD has a handful of Qt WebEngine-based browsers. Falkon, and Otter-Browser, and qutebrowser and probably others, too. All of them can run into issues on FreeBSD with GPU-accelerated rendering not working. Let’s look at some of the workarounds.

NetBSD on the Nanopi Neo2

The NanoPi NEO2 from FriendlyARM has been serving me well since 2018, being my test machine for OpenBSD/arm64 related things.
As NetBSD/evbarm finally gained support for AArch64 in NetBSD 9.0, released back in February, I decided to give it a try on this device. The board only has 512MB of RAM, and this is where NetBSD really shines. Things have become a lot easier since jmcneill@ now provides bootable ARM images for a variety of devices, including the NanoPi NEO2.

I'm back into the grind of FreeBSD's wireless stack and 802.11ac

Yes, it's been a while since I posted here and yes, it's been a while since I was actively working on FreeBSD's wireless stack. Life's been .. well, life. I started the ath10k port in 2015. I wasn't expecting it to take 5 years, but here we are. My life has changed quite a lot since 2015 and a lot of the things I was doing in 2015 just stopped being fun for a while.
But the stars have aligned and it's fun again, so here I am.

News Roundup

Some thoughts on us overlooking Illumos's syseventadm

In a comment on my praise of ZFS on Linux's ZFS event daemon, Joshua M. Clulow noted that Illumos (and thus OmniOS) has an equivalent in syseventadm, which dates back to Solaris. I hadn't previously known about syseventadm, despite having run Solaris fileservers and OmniOS fileservers for the better part of a decade, and that gives me some tangled feelings.

When Unix learned to reboot

Recently, a friend asked me the history of halt, and when did we have to stop with the sync / sync / sync dance before running halt or reboot. The two are related, it turns out.

DragonFlyBSD Lands New EXT2/3/4 File-System Driver

While DragonFlyBSD has its own, original HAMMER2 file-system, for those needing to access data from EXT2/EXT3/EXT4 file-systems, there is a brand new "ext2fs" driver implementation for this BSD operating system.
DragonFlyBSD has long offered an EXT2 file-system driver (that also handles EXT3 and EXT4) while hitting their Git tree this week is a new version. The new sys/vfs/ext2fs driver, which will ultimately replace their existing sys/gnu/vfs/ext2fs driver is based on a port from FreeBSD code. As such, this driver is BSD licensed rather than GPL. But besides the more liberal license to jive with the BSD world, this new driver has various feature/functionality improvements over the prior version. However, there are some known bugs so for the time being both file-system drivers will co-exist.

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.

Emulex: The Cheapest 10gbe for Your Homelab

Years ago, the hunt for the cheapest 10gbe NICs resulted in buying Mellanox ConnectX-2 single-port 10gbe network cards from eBay for around $10. Nowadays those cards have increased in cost to around $20-30. While still cheap, not quite the cheapest. There are now alternatives!
Before diving into details, let’s get something very clear. If you want the absolute simplest plug-and-play 10gbe LAN for your homelab, pay the extra for Mellanox. If you’re willing to go hands-on, do some simple manual configuration and installation, read on for my experiences with Emulex 10gbe NICs.
Emulex NICs can often be had for around $15 on eBay, sometimes even cheaper. I recently picked up a set of 4 of these cards, which came bundled with 6 SFP+ 10g-SR modules for a grand total of $47.48. Considering I can usually find SFP+ modules for about $5/ea, these alone were worth $30.

I have also tried some Solarflare cards that I found cheap, they work ok, but are pickier about optics, and tend to be focused on low-latency, so often don’t manage to saturate the full 10 gbps, topping out around 8 gbps.

I have been using fs.com for optics, patch cables, and DACs. I find DACs are usually cheaper if you are just going between a server and a switch in the same rack, or direct between 2 servers. ***

In Search of 2.11BSD, as released

Almost all of the BSD releases have been well preserved. If you want to find 1BSD, or 2BSD or 4.3-TAHOE BSD you can find them online with little fuss. However, if you search for 2.11BSD, you'll find it easily enough, but it won't be the original. You'll find either the latest patched version (2.11BSD pl 469), or one of the earlier popular version (pl 430 is popular). You can even find the RetroBSD project which used 2.11BSD as a starting point to create systems for tiny mips-based PIC controllers. You'll find every single patch that's been issued for the system.

Fakecracker: NetBSD as a Function Based MicroVM

In November 2018 AWS published an Open Source tool called Firecracker, mostly a virtual machine monitor relying on KVM, a small sized Linux kernel, and a stripped down version of Qemu. What baffled me was the speed at which the virtual machine would fire up and run the service. The whole process is to be compared to a container, but safer, as it does not share the kernel nor any resource, it is a separate and dedicated virtual machine.
If you want to learn more on Firecracker‘s internals, here’s a very well put article.

First powerpc64 snapshots available for OpenBSD

Since we reported the first bits of powerpc64 support going into the tree on 16 May, work has progressed at a steady pace, resulting in snapshots now being available for this platform.
So, if you have a POWER9 system idling around, go to your nearest mirror and fetch this snapshot. Keep in mind that as this is still very early days, very little handholding is available - you are basically on your own.

OPNsense 20.1.8 released

Sorry about the delay while we chased a race condition in the updates back to an issue with the latest FreeBSD package manager updates. For now we reverted to our current version but all relevant third party packages have been updated as updates became available over the last weeks, e.g. cURL and Python, and hostapd / wpa_supplicant amongst others.

Chasing a bad commit

While working on a big project where multiple teams merge their feature branches frequently into a release Git branch, developers often run into situations where they find that some of their work have been either removed, modified or affected by someone else's work accidentally. It can happen in smaller teams as well. Two features could have been working perfectly fine until they got merged together and broke something. That's a highly possible case. There are many other cases which could cause such hard to understand and subtle bugs which even continuous integration (CI) systems running the entire test suite of our projects couldn't catch.
We are not going to discuss how such subtle bugs can get into our release branch because that's just a wild territory out there. Instead, we can definitely discuss about how to find a commit that deviated from an expected outcome of a certain feature. The deviation could be any behaviour of our code that we can measure distinctively — either good or bad in general.

Getting Started with NetBSD on the Pinebook Pro

If you buy a Pinebook Pro now, it comes with Manjaro Linux on the internal eMMC storage. Let’s install NetBSD instead!
The easiest way to get started is to buy a decent micro-SD card (what sort of markings it should have is a science of its own, by the way) and install NetBSD on that. On a warm boot (i.e. when rebooting a running system), the micro-SD card has priority compared to the eMMC, so the system will boot from there.

A FreeBSD developer has borrowed some of the NetBSD code to get audio working on RockPro64 and Pinebook Pro: https://twitter.com/kernelnomicon/status/1282790609778905088 ***

FreeBSD on the Intel 10th Gen i3 NUC

I have ended up with some 10th Gen i3 NUC's (NUC10i3FNH to be specific) to put to work in my testbed. These are quite new devices, the build date on the boxes is 13APR2020. Before I figure out what their true role is (one of them might have to run linux) I need to install FreeBSD -CURRENT and see how performance and hardware support is.

pf table size check and change

Did you know there’s a default size limit to pf’s state table? I did not, but it makes sense that there is one. If for some reason you bump into this limit (difficult for home use, I’d think), here’s how you change it
There is a table-entries limit specified, you can see current settings with
'pfctl -s all'. You can adjust the limits in the /etc/pf.conf file
containing the rules with a line like this near the top:
set limit table-entries 100000

In the original mail thread, there is mention of the FreeBSD sysctl net.pf.request_maxcount, which controls the maximum number of entries that can be sent as a single ioctl(). This allows the user to adjust the memory limit for how big of a list the kernel is willing to allocate memory for. ***

Throw-Away Browser on FreeBSD With "pot" Within 5 Minutes

pot is a great and relatively new jail management tool. It offers DevOps style provisioning and can even be used to provide Docker-like, scalable cloud services together with nomad and consul (more about this in Orchestrating jails with nomad and pot).

Today I will be creating a OpenBSD guest via bhyve on OmniOS. I will also be adding a Pass Through Ethernet Controller so I can have a multi-homed guest that will serve as a firewall/router.
This post will cover setting up bhyve on OmniOS, so it will also be a good introduction to bhyve. As well, I look into OpenBSD’s uEFI boot loader so if you have had trouble with this, then you are in the right place.

BSD versus Linux distribution development

Q: Comparing-apples-to-BSDs asks: I was reading one of the old articles from the archive. One of the things mentioned was how the BSDs have a distinct approach in terms of packaging the base system relative to userland apps, and that the Linux distros at the time were not following the same practice. Are there Linux distros that have adopted the same approach in modern times? If not, are there technical limitations that are preventing them from doing so, such as some distros supporting multiple kernel versions maybe?
DistroWatch answers: In the article mentioned above, I made the observation that Linux distributions tend to take one of two approaches when it comes to packaging software. Generally a Linux distribution will either offer a rolling release, where virtually all packages are regularly upgraded to their latest stable releases, or a fixed release where almost all packages are kept at a set version number and only receive bug fixes for the life cycle of the distribution. Projects like Arch Linux and Void are popular examples of rolling, always-up-to-date distributions while Fedora and Ubuntu offer fixed platforms.

My FreeBSD Laptop Build

I have always liked Thinkpad hardware and when I started to do more commuting I decided I needed something that had a decent sized screen but fit well on a bus. Luckily about this time Lenovo gave me a nice gift in the Thinkpad X390. Its basically the famous X2xx series but with a 13” screen and smaller bezel.
So with this laptop I figured it was time to actually put the docs together on how I got my FreeBSD workstation working on it. I will here in the near future have another post that will cover this for HardenedBSD as well since the steps are similar but have a few extra gotchas due to the extra hardening.

yubikey-agent on FreeBSD

Some time ago Filippo Valsorda wrote yubikey-agent, seamless SSH agent for YubiKeys. I really like YubiKeys and worked on the FreeBSD support for U2F in Chromium and pyu2f, getting yubikey-agent ported looked like an interesting project. It took some hacking to make it work but overall it wasn’t hard. Following is the roadmap on how to get it set up on FreeBSD. The actual details depend on your system (as you will see)

Manage Kubernetes clusters from OpenBSD

This should work with OpenBSD 6.7. I write this while the source tree is locked for release, so even if I use -current this is as close as -current gets to -release
Update 2020-06-05: we now have a port for kubectl. So, at least in -current things get a bit easier.

History of FreeBSD Part 1: Unix and BSD

FreeBSD, a free and open-source Unix-like operating system has been around since 1993. However, its origins are directly linked to that of BSD, and further back, those of Unix. During this History of FreeBSD series, we will talk about how Unix came to be, and how Berkeley’s Unix developed at Bell Labs.

Running Jitsi-Meet in a FreeBSD Jail

Due to the situation with COVID-19 that also lead to people being confined to their homes in South Africa as well, we decided to provide a (freely usable of course) Jitsi Meet instance to the community being hosted in South Africa on our FreeBSD environment.
That way, communities in South Africa and beyond have a free alternative to the commercial conferencing solutions with sometimes dubious security and privacy histories and at the same time improved user experience due to the lower latency of local hosting.

FreeBSD uses bugzilla for tracking bugs, taking feature requests, regressions and issues in the Operating System. The web interface for bugzilla is okay, but if you want to do a lot of batch operations it is slow to deal with. We are planning to run a bugsquash on July 11th and that really needs some tooling to help any hackers that show up process the giant bug list we have.
