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.

News Roundup

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. ***

352: Introducing Randomness

JT Pennington — Thu, 28 May 2020 08:00:00 -0400

A brief introduction to randomness, logs grinding netatalk to a halt, NetBSD core team changes, Using qemu guest agent on OpenBSD kvm/qemu guests, WireGuard patchset for OpenBSD, FreeBSD 12.1 on a laptop, and more.

Headlines

Entropy

A brief introduction to randomness

Problem: Computers are very predictable. This is by design.

But what if we want them to act unpredictably? This is very useful if we want to secure our private communications with randomized keys, or not let people cheat at video games, or if we're doing statistical simulations or similar.

Logs grinding Netatalk on FreeBSD to a hault

I’ve heard it said the cobbler’s children walk barefoot. While posessing the qualities of a famed financial investment strategy, it speaks to how we generally put more effort into things for others than ourselves; at least in business.
The HP Microserver I share with Clara is a modest affair compared to what we run at work. It has six spinning rust drives and two SSDs which are ZFS-mirrored; not even in a RAID 10 equivalent. This is underlaid with GELI for encryption, and served to our Macs with Netatalk over gigabit Ethernet with jumbo frames.

News Roundup

NetBSD Core Team Changes

Matt Thomas (matt@) has served on the NetBSD core team for over ten years, and has made many contributions, including ELF functionality, being the long-time VAX maintainer, gcc contributor, the generic pmap, and also networking functionality, and platform bring-up over the years. Matt has stepped down from the NetBSD core team, and we thank him for his many, extensive contributions.
Robert Elz (kre@), a long time BSD contributor, has kindly accepted the offer to join the core team, and help us out with the benefit of his experience and advice over many years. Amongst other things, Robert has been maintaining our shell, liaising with the Austin Group, and bringing it up to date with modern functionality.

Using qemu guest agent on OpenBSD kvm/qemu guests

In a post to the ports@ mailing list, Landry Breuil (landry@) shared some of his notes on using qemu guest agent on OpenBSD kvm/qemu guests.

WireGuard patchset for OpenBSD

A while ago I wanted to learn more about OpenBSD development. So I picked a project, in this case WireGuard, to develop a native client for. Over the last two years, with many different iterations, and working closely with the WireGuard's creator (Jason [Jason A. Donenfeld - Ed.], CC'd), it started to become a serious project eventually reaching parity with other official implementations. Finally, we are here and I think it is time for any further development to happen inside the src tree.

FreeBSD 12.1 on a laptop

I’m using FreeBSD again on a laptop for some reasons so expect to read more about FreeBSD here. This tutorial explain how to get a graphical desktop using FreeBSD 12.1.

Headlines

LLVM santizers and GDB regression test suite.

As NetBSD-9 is branched, I have been asked to finish the LLVM sanitizer integration. This work is now accomplished and with MKLLVM=yes build option (by default off), the distribution will be populated with LLVM files for ASan, TSan, MSan, UBSan, libFuzzer, SafeStack and XRay.

I have also transplanted basesystem GDB patched to my GDB repository and managed to run the GDB regression test-suite.

NetBSD distribution changes

I have enhanced and imported my local MKSANITIZER code that makes whole distribution sanitization possible. Few real bugs were fixed and a number of patches were newly written to reflect the current NetBSD sources state. I have also merged another chunk of the fruits of the GSoC-2018 project with fuzzing the userland (by plusun@).

News Roundup

Ada—The Language of Cost Savings?

Many myths surround the Ada programming language, but it continues to be used and evolve at the same time. And while the increased adoption of Ada and SPARK, its provable subset, is slow, it’s noticeable. Ada already addresses more of the features found in found in heavily used embedded languages like C+ and C#. It also tackles problems addressed by upcoming languages like Rust.

Chris concludes, “Development technologies have a profound impact on one of the largest and most variable costs associated with embedded-system engineering—labor. At a time when on-time system deployment can not only impact customer satisfaction, but access to services revenue streams, engineering team efficiency is at a premium. Our research showed that programming language choices can have significant influence in this area, leading to shorter projects, better schedules and, ultimately, lower development costs. While a variety of factors can influence and dictate language choice, our research showed that Ada’s evolution has made it an increasingly compelling option for engineering organizations, providing both technically and financially sound solution.”

In general, Ada already makes embedded “programming in the large” much easier by handling issues that aren’t even addressed in other languages. Though these features are often provided by third-party software, it results in inconsistent practices among developers. Ada also supports the gamut of embedded platforms from systems like Arm’s Cortex-M through supercomputers. Learning Ada isn’t as hard as one might think and the benefits can be significant.

FreeBSD core team appoints a WG to explore transitioning from Subversion to Git.

The FreeBSD Core Team is the governing body of FreeBSD.

Core approved source commit bits for Doug Moore (dougm), Chuck Silvers (chs), Brandon Bergren (bdragon), and a vendor commit bit for Scott Phillips (scottph).

The annual developer survey closed on 2019-04-02. Of the 397 developers, 243 took the survey with an average completion time of 12 minutes. The public survey closed on 2019-05-13. It was taken by 3637 users and had a 79% completion rate. A presentation of the survey results took place at BSDCan 2019.

The core team voted to appoint a working group to explore transitioning our source code 'source of truth' from Subversion to Git. Core asked Ed Maste to chair the group as Ed has been researching this topic for some time. For example, Ed gave a MeetBSD 2018 talk on the topic.

There is a variety of viewpoints within core regarding where and how to host a Git repository, however core feels that Git is the prudent path forward.

36: Let's Get RAID

JT Pennington — Wed, 07 May 2014 08:00:00 -0400

This week on the show we'll be showing you how to set up RAID arrays in both FreeBSD and OpenBSD. There's also an interview with David Chisnall - of the FreeBSD core team - about the switch to Clang and a lot more. As usual, we'll be dropping the latest news and answering your emails, so sit back and enjoy some BSD Now - the place to B.. SD.

OpenBSD 5.5 released

If you ordered a CD set then you've probably had it for a little while already, but OpenBSD has formally announced the public release of 5.5
This is one of the biggest releases to date, with a very long list of changes and improvements
Some of the highlights include: time_t being 64 bit on all platforms, release sets and binary packages being signed with the new signify tool, a new autoinstall feature of the installer, SMP support on Alpha, a new AViiON port, lots of new hardware drivers including newer NICs, the new vxlan driver, relayd improvements, a new pf queue system for bandwidth shaping, dhcpd and dhclient fixes, OpenSMTPD 5.4.2 and all its new features, position-independent executables being default for i386, the RNG has been replaced with ChaCha20 as well as some other security improvements, FUSE support, tmpfs, softraid partitions larger than 2TB and a RAID 5 implementation, OpenSSH 6.6 with all its new features and fixes... and a lot more
The full list of changes is HUGE, be sure to read through it all if you're interested in the details
If you're doing an upgrade from 5.4 instead of a fresh install, pay careful attention to the upgrade guide as there are some very specific steps for this version
Also be sure to apply the errata patches on your new installations... especially those OpenSSL ones (some of which still aren't fixed in the other BSDs yet)
On the topic of errata patches, the project is now going to also send them out (signed) via the announce mailing list, a very welcome change
Congrats to the whole team on this great release - 5.6 is going to be even more awesome with "Libre"SSL and lots of other stuff that's currently in development ***

FreeBSD foundation funding highlights

The FreeBSD foundation posts a new update on how they're spending the money that everyone donates
"As we embark on our 15th year of serving the FreeBSD Project and community, we are proud of what we've done to help FreeBSD become the most innovative, reliable, and high-performance operation system"
During this spring, they want to highlight the new UEFI boot support and newcons
There's a lot of details about what exactly UEFI is and why we need it going forward
FreeBSD has also needed some updates to its console to support UTF8 and wide characters
Hopefully this series will continue and we'll get to see what other work is being sponsored ***

OpenSSH without OpenSSL

The OpenSSH team has been hard at work, making it even better, and now OpenSSL is completely optional
Since it won't have access to the primitives OpenSSL uses, there will be a trade-off of features vs. security
This version will drop support for legacy SSH v1, and the only two cryptographic algorithms supported are an in-house implementation of AES in counter mode and the new combination of the Chacha20 stream cipher with Poly1305 for packet integrity
Key exchange is limited to elliptic curve Diffie-Hellman and the newer Curve25519 KEXs
No support for RSA, DSA or ECDSA public keys - only Ed25519
It also includes a new buffer API and a set of wrappers to make it compatible with the existing API
Believe it or not, this was planned before all the heartbleed craziness
Maybe someday soon we'll have a mini-openssh-portable in FreeBSD ports and NetBSD pkgsrc, would be really neat ***

BSDMag's April 2014 issue is out

The free monthly BSD magazine has got a new issue available for download
This time the articles include: pascal on BSD, an introduction to revision control systems and configuration management, deploying NetBSD on AWS EC2, more GIMP tutorials, an AsiaBSDCon 2014 report and a piece about how easily credit cards are stolen online
Anyone can contribute to the magazine, just send the editors an email about what you want to write
No Linux articles this time around, good ***

BSDTalk episode 240

Our buddy Will Backman has uploaded a new episode of BSDTalk, this time with our other buddy GNN as the guest - mainly to talk about NTP and keeping reliable time
Topics include the specific details of crystals used in watches and computers to keep time, how temperature affects the quality, different sources of inaccuracy, some general NTP information, why you might want extremely precise time, different time sources (GPS, satellite, etc), differences in stratum levels, the problem of packet delay and estimating the round trip time, some of the recent NTP amplification attacks, the downsides to using UDP instead of TCP and... much more
GNN also talks a little about the Precision Time Protocol and how it's different than NTP
Two people we've interviewed talking to each other, awesome
If you're interested in NTP, be sure to see our tutorial too ***

m2k14 trip reports

We've got a few more reports from the recent OpenBSD hackathon in Morocco
The first one is from Antoine Jacoutot (who is a key GNOME porter and gave us the screenshots for the OpenBSD desktop tutorial)
"Since I always fail at actually doing whatever I have planned for a hackathon, this time I decided to come to m2k14 unprepared about what I was going to do"
He got lots of work done with ports and pushing GNOME-related patches back up to the main project, then worked on fixing ports' compatibility with LibreSSL
Speaking of LibreSSL, there's an article all would-be portable version writers should probably read and take into consideration
Jasper Adriaanse also writes about what he got done over there
He cleaned up and fixed the puppet port to work better with OpenBSD ***

Why you should use FreeBSD on your cloud VPS

Here we have a blog post from Atlantic, a VPS and hosting provider, about 10 reasons for using FreeBSD
Starts off with a little bit of BSD history for those who are unfamiliar with it and only know Linux and Windows
The 10 reasons are: community, stability, collaboration, ease of use, ports, security, ZFS, GEOM, sound and having lots of options
The post goes into detail about each of them and why FreeBSD makes a great choice for a VPS OS ***

PCBSD weekly digest

Big changes coming in the way PCBSD manages software
The PBI system, AppCafe and related tools are all going to use pkgng now
The AppCafe will no longer be limited to PBIs, so much more software will be easily available from the ports tree
New rating system coming soon and much more ***
