[$] A panel discussion on the kernel's code of conduct

수, 2018/11/21 - 1:53오전
There has been a great deal of discussion around the kernel project's recently adopted code of conduct (CoC), but little of that has happened in an open setting. That changed to an extent when a panel discussion was held during the Kernel Summit track at the 2018 Linux Plumbers Conference. Panelists Mishi Choudhary, Olof Johansson, Greg Kroah-Hartman, and Chris Mason took on a number of issues surrounding the CoC in a generally calm and informative session.

[$] The kernel developer panel at LPC

화, 2018/11/20 - 2:36오전
The closing event at the 2018 Linux Plumbers Conference (LPC) was a panel of kernel developers. The participants were Laura Abbott, Anna-Maria Gleixner, Shuah Khan, Julia Lawall, and Anna Schumaker; moderation was provided by Kate Stewart. This fast-moving discussion covered the challenges of kernel development, hardware vulnerabilities, scaling the kernel, and more.

Kernel prepatch 4.20-rc3

월, 2018/11/19 - 11:38오후
The 4.20-rc3 kernel prepatch is out for testing. "The changes in rc3 are pretty tiny, which means that the statistics look slightly different from the usual ones - drivers only account for less than a third of the patch, for example."

[$] Bringing the Android kernel back to the mainline

금, 2018/11/16 - 5:17오전
Android devices are based on the Linux kernel but, since the beginning, those devices have not run mainline kernels. The amount of out-of-tree code shipped on those devices has been seen as a problem for most of this time, and significant resources have been dedicated to reducing it. At the 2018 Linux Plumbers Conference, Sandeep Patil talked about this problem and what is being done to address it. The dream of running mainline kernels on Android devices has not yet been achieved, but it may be closer than many people think.

Red Hat Enterprise Linux 8 Beta

금, 2018/11/16 - 3:44오전
Red Hat has announced the release of RHEL 8 Beta. "Red Hat Enterprise Linux 8 Beta introduces the concept of Application Streams to deliver userspace packages more simply and with greater flexibility. Userspace components can now update more quickly than core operating system packages and without having to wait for the next major version of the operating system. Multiple versions of the same package, for example, an interpreted language or a database, can also be made available for installation via an application stream. This helps to deliver greater agility and user-customized versions of Red Hat Enterprise Linux without impacting the underlying stability of the platform or specific deployments."

[$] A report from the Automated Testing Summit

목, 2018/11/15 - 7:21오전

In the first session of the Testing & Fuzzing microconference at the 2018 Linux Plumbers Conference (LPC), Kevin Hilman gave a report on the recently held Automated Testing Summit (ATS). Since the summit was an invitation-only gathering of 35 people, there were many at LPC who were not at ATS but had a keen interest in what was discussed. The summit came out of a realization that there is a lot of kernel testing going on in various places, but not a lot of collaboration between those efforts, Hilman said.

[$] Device-tree schemas

목, 2018/11/15 - 3:56오전
Device trees have become ubiquitous in recent years as a way of describing the hardware layout of non-discoverable systems, such as many ARM-based devices. The device-tree bindings define how a particular piece of hardware is described in a device tree. Drivers then implement those bindings. The device-tree documentation shows how to use the bindings to describe systems: which properties are available and which values they may have. In theory, the bindings, drivers and documentation should be consistent with each other. In practice, they are often not consistent and, even when they are, using those bindings correctly in actual device trees is not a trivial task. As a result, developers have been considering formal validation for device-tree files for years. Recently, Rob Herring proposed a move to a more structured documentation format for device-tree bindings using JSON Schema to allow automated validation.

[$] Debian, Rust, and librsvg

수, 2018/11/14 - 9:46오전

Debian supports many architectures and, even for those it does not officially support, there are Debian ports that try to fill in the gap. For most user applications, it is mostly a matter of getting GCC up and running for the architecture in question, then building all of the different packages that Debian provides. But for packages that need to be built with LLVM—applications or libraries that use Rust, for example—that simple recipe becomes more complicated. How much the lack of Rust support for an unofficial architecture should hold back the rest of the distribution was the subject of a somewhat acrimonious discussion recently.

[$] C library system-call wrappers, or the lack thereof

화, 2018/11/13 - 8:01오전
User-space developers may be accustomed to thinking of system calls as direct calls into the kernel. Indeed, the first edition of The C Programming Language described read() and write() as "a direct entry into the operating system". In truth, user-level "system calls" are just functions in the C library like any other. But what happens when the developers of the C library refuse to provide access to system calls they don't like? The result is an ongoing conflict that has recently flared up again; it shows some of the difficulties that can arise when the system as a whole has no ultimate designer and the developers are not talking to each other.
