Adrian Ratiu continues his series on eBPF with part 3, which looks at various ways to write and build eBPF programs. It starts by looking at using 'restricted C' with the LLVM eBPF compiler, moves into looking at the BPF Compiler Collection (BCC), then bpftrace, and finally...
The recently discovered vulnerability in Thunderbolt has restarted discussions about protecting the kernel against untrusted, hotpluggable hardware. That vulnerability, known as Thunderclap, allows a hostile external device to exploit Input-Output Memory Management Unit...

Over at Opensource.com, Jason Brock tries out Linux graphics tools, with an eye toward their ability to replace the proprietary tools he uses on a day-to-day basis. Overall, the tools held their own for a variety of tasks (e.g. logo and ad design, publication layout), though ...
The release of the 5.1-rc6 kernel prepatch on April 21 indicates that the 5.1 development cycle is getting close to its conclusion. So naturally the time has come to put together some statistics describing where the changes merged for 5.1 came from. It is, for the most part,...

An April Fools joke that went sour seems to be at least the proximate cause for a rather large upheaval in the Devuan community. For much of April 1 (or March 31 depending on time zone), the Devuan web site looked like it had been taken over by attackers, which was worrisome ...
The Mozilla Blog introduces Mozilla's 2019 Internet Health Report. 'In the Report’s three spotlight articles, we unpack three big issues: One examines the need for better machine decision making — that is, asking questions like Who designs the algorithms? and What data...
In his keynote at the 2019 Legal and Licensing Workshop (LLW), longtime workshop participant Andrew Wilson looked at the past, but he went much further back than, say, the history of free software—or even computers. His talk looked at technological liberty in the context...

Intel's 'Software Guard Extensions' (SGX) feature allows the creation of encrypted 'enclaves' that cannot be accessed from the rest of the system. Normal code can call into an enclave, but only code running inside the enclave itself can access the data stored there. SGX is...
Here's an article on the V8 blog describing the work that was done to mitigate Spectre vulnerabilities in the V8 JavaScript engine. 'Our research reached the conclusion that, in principle, untrusted code can read a process’s entire address space using Spectre and side...

The Erlang community mourns the loss of Joe Armstrong, known as the father of Erlang. 'He was part of the Erlang landscape, always interested in what people had to say. His passion and enjoyment about the craft, even in his 60s, was still high up at levels I don't even know...

Fermilab has maintained Scientific Linux, a derivative of Red Hat Enterprise Linux, for many years. That era is coming to an end, though: 'Toward that end, we will deploy CentOS 8 in our scientific computing environments rather than develop Scientific Linux 8. We will...
The election for the Debian project leader has concluded; the leader for the next year will be Sam Hartman. See this page for the details of the vote.
The 5.1-rc6 kernel prepatch is out for testing. 'It's Easter Sunday here, but I don't let little things like random major religious holidays interrupt my kernel development workflow. The occasional scuba trip? Sure. But everybody sitting around eating traditional foods? No....
