Linux 4.17 Release – Main Changes, Arm & MIPS Architectures

Linus Torvalds released Linux 4.17 last Sunday: So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached. And while I would have liked even less changes, I really didn’t get the feeling that another week would help the release in any way, so here we are, with 4.17 released. No, I didn’t call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_distant future, and I’m told all the release scripts on are ready for it, but I didn’t feel there was any real reason for it. I suspect that around 4.20 – which is I run out of fingers and toes to keep track of minor releases, and thus start getting mightily confused – I’ll switch […]

Linux 4.16 Release – Main Changes, Arm and MIPS Architectures

Linus Torvalds has just released Linux 4.16: So the take from final week of the 4.16 release looks a lot like rc7, in that about half of it is networking. If it wasn’t for that, it would all be very small and calm. We had a number of fixes and cleanups elsewhere, but none of it made me go “uhhuh, better let this soak for another week”. And davem didn’t think the networking was a reason to delay the release, so I’m not. End result: 4.16 is out, and the merge window for 4.17 is open and I’ll start doing pull requests tomorrow. Outside of networking, most of the last week was various arch fixlets (powerpc, arm, x86, arm64), some driver fixes (mainly scsi and rdma) and misc other noise (documentation, vm, perf). The appended shortlog gives an overview of the details (again, this is only the small stuff in […]

Protecode System 4 Helps Managing Software Package Data Exchange (SPDX) Files

Some days ago, I posted a presentation about SPDX (Software Portable Data Exchange), a new standard file format to share open source licenses. This took place at the Linux Embedded Linux Conference, mid- February 2012 and the presenter said SPDX was still in its infancy, nobody formally adopted it and current tools would take input from an excel file and convert it into an XML/RDF SPDX file. However, Protecode, a company specialized in open source license management solutions, has already a management suite called Protecode System 4 that can handle SPDX format among other things. Here’s how the company describes Protecode System 4: Protecode System 4 is a complete license management solution for all stages of the software development process. Protecode System 4 enables users to manage open source and third party license compliance by providing a list of all open source components that exist in a software product along […]

The Power of SPDX (Software Package Data Exchange) – ELC 2012

Mark Gisi, Sr. Manager of Intellectual Property at Wind River , discusses SPDX (Software Package Data Exchange) at Embedded Linux Conference 2012. Abstract: Sharing Critical Licensing Information within a Linux Device Supply Chain Embedded Linux device runtimes are derived from 100s of open source packages. A common misunderstanding is that just one or two licenses govern a given open source package, when in fact; often a dozen or more apply. Therefore a device runtime could be under 100s of unique licenses. Determining which licenses are relevant is challenging. SPDX, the Linux Foundation’s license exchange format, provides an effective mechanism for recording and sharing licensing information within a device vendor supply chain. We present an overview of SPDX along with a detailed source code example on how to create and extract relevant licensing information. The target audience includes developers, engineering managers, release operation engineers and license compliance professionals. They will learn […]
