The Linux Plumbers Conference (LPC) registration web site has been showing "sold out" recently because the cap on early bird registrations
was reached. We are happy to report that we have reviewed the registration numbers for this year's conference and were able to open more early bird registration slots. Beyond that, regular registration will open July 1st. Please note that speakers and microconference runners get free passes to LPC, as do some microconference presenters, so that may be another way to attend the conference. Time is running out for new refereed-track and microconference proposals, so visit the CFP page soon. Topics for accepted microconferences are welcome as well.

LPC will be held in Lisbon, Portugal from Monday, September 9 through Wednesday, September 11.

We hope to see you there!

We are pleased to announce that the Tracing Microconference has been accepted into the 2019 Linux Plumbers Conference! Its return to Linux Plumbers shows that tracing is not finished in Linux, and there continue to be challenging problems to solve.

There's a broad list of ways to perform Tracing in Linux. From the original mainline Linux tracer, Ftrace, to profiling tools like perf, more complex customized tracing like BPF and out-of-tree tracers like LTTng, systemtap, and Dtrace. Part of the trouble with tracing within Linux is that there is so much to choose from. Each of these have their own audience, but there is a lot of overlap. This year's theme is to find those common areas and combine them into common utilities.

There is also a lot of new work that is happening and discussions between top maintainers will help keep everyone in sync, and provide good direction for the future.

Expected topics include:

• bpf tracing - Anything to do with BPF and tracing combined
• libtrace - Making libraries from our tools
• Packaging - Packaging these libraries
• babeltrace - Anything that we need to do to get all tracers talking to each other
• Those pesky tracepoints - How to get what we want from places where trace events are taboo
• Changing tracepoints - Without breaking userspace
• Function tracing - Modification of current implementation
• Rewriting of the Function Graph tracer - Can kretprobes and function graph tracer merge as one
• Histogram and synthetic tracepoints - Making a better interface that is more intuitive to use

Come and join us and not only learn but help direct the future progress of tracing inside the Linux kernel and beyond!

If you have another tracing topic idea, please send it to Steven Rostedt: rostedt@goodmis.org .

We hope to see you there!

Seen an amusing blog post today on the topic of the hideous debacle that is Google Fi (on top of being a virtual network). Here's the best part though:

About a year ago I tried to get my parents to switch from AT&T to Google Fi. I even made a spreadsheet for my dad (who likes those sorts of things) about how much money he could save. He wasn't interested. His one point was that at anytime he can go in and get help from an AT&T rep. I kept asking "Who cares? Why would you ever need that?". Now I know. He was paying almost $60 a month premium for the opportunity to able to talk to a real person, face-to-face! I would gladly pay that now.

Respect your elders!

With the demise of Google+, I've decided to try to resurrect my blog. Previously, I was using Wordpress, but I've decided that it's just too risky from a security perspective. So I've decided my blog over to Hugo.

A consequence of this switch is that all of the Wordpress comments have been dropped, at least for now.

The open nature of the RISC-V ecosystem has allowed contributions from both academia and industry leading to an unprecedented number of new hardware design proposals in a very short time span. Linux support is the key to enabling these new hardware options. Since last year's Plumbers, many kernel features were added to RISC-V. To name a few, we now have out-of-box 32-bit and eBPF support, some key issues with Linux boot process have been addressed, and hypervisor support is on its way.

Last year's RISC-V microconference was such a success that we would like to repeat that again this year by focusing on finding solutions and discussing ideas that require kernel changes.

Topics for this year microconference are expected to cover:

• RISC-V Platform Specification Progress, including some extensions such as power management
• Fixing the Linux boot process in RISC-V (RISC-V now has better support for open source boot loaders like U-Boot and coreboot compared to last year. As a result of this developers can use the same boot loaders to boot Linux on RISC-V as they do in other architectures, but there's more work to be done)
• RISC-V hypervisor emulation
• NOMMU Linux for RISC-V
• Any other subject of interest

If you're interested in participating in this microconference or have other topics to propose, please contact Atish Patra (atish.patra@wdc.com) or Palmer Dabbelt (palmer@dabbelt.com)

LPC will be held in Lisbon, Portugal from Monday, September 9 through Wednesday, September 11.

We hope to see you there!

I've released man-pages-5.01. The release tarball is available on kernel.org. The browsable online pages can be found on man7.org. The Git repository for man-pages is available on kernel.org.

This release resulted from patches, bug reports, reviews, and comments from just over 20 contributors. The release is smaller release than typical; it includes just over 70 commits that changed just over 40 pages.

The most notable of the changes in man-pages-5.01 is the following:

• The tsearch(3) page adds documentation of the new twalk_r() function that is added in the upcoming glibc 2.30 release. Thanks to Florian Weimer.

Seen in a blog entry by Martin Tournoij (via):

I've been happily programming Python for over a decade, so I'm used to significant whitespace, but sometimes I'm still struggling with YAML. In Python the drawbacks and loss of clarity are contained by not having functions that are several pages long, but data or configuration files have no such natural limits to their length.

[...]

YAML may seem 'simple' and 'obvious' when glancing at a basic example, but turns out it's not. The YAML spec is 23,449 words; for comparison, TOML is 3,339 words, JSON is 1,969 words, and XML is 20,603 words.

There's more where the above came from. In particular, the portability issues are rather surprising.

Unfortunately for me, OpenStack TripleO is based on YAML.

We are pleased to announce that the BPF microconference has been accepted into the 2019 Linux Plumbers Conference! Last year's BPF microconference was such a success that it will be held again this year.

BPF along with its just-in-time (JIT) compiler inside the Linux kernel allows for versatile programmability of the kernel and plays a major role in networking (XDP, tc BPF, etc.), tracing (kprobes, uprobes, tracepoints) and security (seccomp, landlock) subsystems.

Since last year's Plumbers Conference, many of the discussed improvements have been tackled and found their way into the Linux kernel such as significant steps towards allowing for a compile-once paradigm with the help of BTF and global data support as well as considerable verifier scalability improvements to name a few. The topics proposed for this year's event include:

- libbpf, loader unification
- Standardized BPF ELF format
- Multi-object semantics and linker-style logic for BPF loaders
- Verifier scalability work towards 1 million instructions
- Sleepable BPF programs
- BPF loop support
- Indirect calls in BPF
- Unprivileged BPF
- BPF type format (BTF)
- BPF timers
- bpftool
- LLVM BPF backend, JITs and BPF offloading
- and more

Come join us and participate in the decision making of one of the most cutting edge advancements in the Linux kernel!

See here for a detailed preview of the proposed and accepted topics. Please feel free to submit your discussion proposals to Alexei or Daniel: lpc-bpf@vger.kernel.org

We hope to see you there!

Wow, they better not be building Boeings from this crap:

NASA Launch Services Program (LSP) investigators have determined the technical root cause for the Taurus XL launch failures of NASA's Orbiting Carbon Observatory (OCO) and Glory missions in 2009 and 2011, respectively: faulty materials provided by aluminum manufacturer, Sapa Profiles (SPI). LSP's technical investigation led to the involvement of NASA's Office of the Inspector General and the U.S. Department of Justice (DOJ). DOJ's efforts, recently made public, resulted in the resolution of criminal charges and alleged civil claims against SPI, and its agreement to pay $46 million to the U.S. government and other commercial customers. This relates to a 19-year scheme that included falsifying thousands of certifications for aluminum extrusions to hundreds of customers.

BTW, those costly failures probably hastened the sale of Orbital to ATK in 2015. There were repercussions for the personnell running the Taurus program as well.

lwn.net just featured an article the sustainability of open source, which seems to be a bit a topic in various places since a while. I've made a keynote at Siemens Linux Community Event 2018 last year which lends itself to a different take on all this:

The slides for those who don't like videos.

This talk was mostly aimed at managers of engineering teams and projects with fairly little experience in shipping open source, and much less experience in shipping open source through upstream cross vendor projects like the kernel. It goes through all the usual failings and missteps and explains why an upstream first strategy is the right one, but with a twist: Instead of technical reasons, it's all based on economical considerations of why open source is succeeding. Fundamentally it's not about the better software, or the cheaper prize, or that the software freedoms are a good thing worth supporting.

Instead open source is eating the world because it enables a much more competitive software market. And all the best practices around open development are just to enable that highly competitive market. Instead of arguing that open source has open development and strongly favours public discussions because that results in better collaboration and better software we put on the economic lens, and private discussions become insider trading and collusions. And that's just not considered cool in a competitive market. Similar arguments can be made with everything else going on in open source projects.

Circling back to the list of articles at the top I think it's worth looking at the sustainability of open source as an economic issue of an extremely competitive market, in other words, as a market failure: Occasionally the result is that no one gets paid, the customers only receive a sub-par product with all costs externalized - costs like keeping up with security issues. And like with other market failures, a solution needs to be externally imposed through regulations, taxation and transfers to internalize all the costs again into the product's prize. Frankly no idea how that would look like in practice though.

Anyway, just a thought, but good enough a reason to finally publish the recording and slides of my talk, which covers this just in passing in an offhand remark.

Update: Fix slides link.
