[$] CVE-less vulnerabilities

수, 2019/06/26 - 5:49오전
More bugs in free software are being found these days, which is good for many reasons, but there are some possible downsides to that as well. In addition, projects like OSS-Fuzz are finding lots of bugs in an automated fashion—many of which may be security relevant. The sheer number of bugs being reported is overwhelming many (most?) free-software projects, which simply do not have enough eyeballs to fix, or even triage, many of the reports they receive. A discussion about that is currently playing out on the oss-security mailing list.

GitLab 12.0

수, 2019/06/26 - 3:04오전
GitLab 12.0 has been released. "GitLab gives users the ability to automatically create review apps for each merge request. This allows anyone to see how the design or UX has been changed. In GitLab 12.0, we are expanding the ability to discuss those changes by bringing the ability to insert visual review tools directly into the Review App itself. With a small code snippet, users can enable designers, product managers, and other stakeholders to quickly provide feedback on a merge request without leaving the app." Other features include the ability to easily access a project's Dependency List, restrict access by IP address, and much more.

Introducing people.kernel.org

화, 2019/06/25 - 11:10오후
Konstantin Ryabitsev has announced a new public blogging platform for kernel developers. "Ever since the demise of Google+, many developers have expressed a desire to have a service that would provide a way to create and manage content in a format that would be more rich and easier to access than email messages sent to LKML. Today, we would like to introduce people.kernel.org, which is an ActivityPub-enabled federated platform powered by WriteFreely and hosted by very nice and accommodating folks at write.as." (LWN looked at WriteFreely back in March).

Changes at the Apache Software Foundation

화, 2019/06/25 - 11:00오후
Here's a statement from the Apache Software Foundation regarding changes in its leadership: "It is with a mix of sadness and appreciation that the ASF Board accepted the resignations of Board Member Jim Jagielski, Chairman Phil Steitz, and Executive Vice President Ross Gardler last month." There is no indication of why all these people decided to leave at the same time.

[$] Lockdown as a security module

화, 2019/06/25 - 5:41오전
Technologies like UEFI secure boot are intended to guarantee that a locked-down system is running the software intended by its owner (for a definition of "owner" as "whoever holds the signing key recognized by the firmware"). That guarantee is hard to uphold, though, if a program run on the system in question is able to modify the running kernel somehow. Thus, proponents of secure-boot technologies have been trying for years to provide the ability to lock down many types of kernel functionality on secure systems. The latest attempt posted by Matthew Garrett, at an eyebrow-raising version 34, tries to address previous concerns by putting lockdown under the control of a Linux security module (LSM).

Canonical backtracks on i386 packages

화, 2019/06/25 - 4:14오전
Canonical has let it be known that minds have been changed about removing all 32-bit x86 support from the Ubuntu distribution. "Thanks to the huge amount of feedback this weekend from gamers, Ubuntu Studio, and the WINE community, we will change our plan and build selected 32-bit i386 packages for Ubuntu 19.10 and 20.04 LTS. We will put in place a community process to determine which 32-bit packages are needed to support legacy software, and can add to that list post-release if we miss something that is needed."

Two years of postmarketOS

화, 2019/06/25 - 1:39오전
PostmarketOS is an Alpine Linux based operating system for mobile devices. The postmarketOS blog takes a look at the project after two years of development. "Wouldn't it be great if you could take any obsolete smartphone from the past ten years and replace its outdated and insecure software with a maintained, modular free software stack? How about then using it as a Raspberry Pi-like device for your next tinkering project? With some constraints, postmarketOS makes this possible today for 139 booting devices. Every single package in the whole OS can be updated, with the only exceptions being the vendor's Linux kernel and firmware blobs (if you plan on using them). In a few cases, it is even possible to switch out the discontinued vendor kernel forks with the upstream kernel releases straight from Linus Torvalds."

Kernel prepatch 5.2-rc6

일, 2019/06/23 - 10:10오후
The 5.2-rc6 kernel prepatch has been released. Linus worries that the volume of changes has increased — but not too much. "With all that out of the way, I'm still reasonably optimistic that we're on track for a calm final part of the release, and I don't think there is anything particularly bad on the horizon." He also notes that, due to travel, he'll be releasing 5.2-rc7 later than usual.

[$] FreeBSD turns 26

토, 2019/06/22 - 7:18오전
The FreeBSD operating system is continuing to make progress, 26 years after it got its name. Among the areas where work is being done is on improved support for RISC-V, FUSE filesystem updates, C runtime changes, and security improvements. FreeBSD Day is celebrated on June 19, in recognition of the date in 1993 when the name FreeBSD was coined for a fork of the 386BSD project. The first official release of FreeBSD did not occur until November 1, 1993, however.

Ahead of FreeBSD Day, the project released its quarterly report for the first quarter of 2019, outlining some of its ongoing efforts. In addition to the quarterly report, the executive director of the FreeBSD Foundation provided LWN with some insights into the state of the project and the foundation that supports it.

[$] Statistics from the 5.2 kernel — and before

금, 2019/06/21 - 11:52오후
As of this writing, just over 13,600 non-merge changesets have been pulled into the mainline repository for the 5.2 development cycle. The time has come, once again, for a look at where that work came from and who supported it. There are some unique aspects to 5.2 that have thrown off some of the usual numbers.

Huang: Open Source Could Be a Casualty of the Trade War

금, 2019/06/21 - 11:07오후
Bunnie Huang writes about the escalating trade wars and how they could be harmful to the open-source community. "Because the administrative action so far against Huawei relies only upon export license restrictions, the Linux Foundation has been able to find shelter under a license exemption for open source software. However, should Huawei be designated as a 'foreign adversary' under EO13873, it greatly expands the scope of the ban because it prohibits transactions with entities under the direction or influence of foreign adversaries. The executive order also broadly includes any information technology including hardware and software with no exemption for open source."

[$] C, Fortran, and single-character strings

금, 2019/06/21 - 12:16오전
The calling interfaces between programming languages are, by their nature, ripe for misunderstandings; different languages can have subtly different ideas of how data should be passed around. Such misunderstandings often have the effect of making things break right away; these are quickly fixed. Others can persist for years or even decades before jumping out of the shadows and making things fail. A problem of the latter variety recently turned up in how some C programs are passing strings to Fortran subroutines, with unpleasant effects on widely used packages like LAPACK.

Kubernetes 1.15 released

목, 2019/06/20 - 11:53오후
The Kubernetes container orchestrator team has announced the release of Kubernetes 1.15; the main themes of this release are "extensibility and continuous improvement". One of the focus areas was on usability and lifecycle stability for clusters: "Work on making Kubernetes installation, upgrade and configuration even more robust has been a major focus for this cycle for SIG Cluster Lifecycle (see our last Community Update). Bug fixes across bare metal tooling and production-ready user stories, such as the high availability use cases have been given priority for 1.15. kubeadm, the cluster lifecycle building block, continues to receive features and stability work required for bootstrapping production clusters efficiently. kubeadm has promoted high availability (HA) capability to beta, allowing users to use the familiar kubeadm init and kubeadm join commands to configure and deploy an HA control plane. An entire new test suite has been created specifically for ensuring these features will stay stable over time." More information can be found in the release notes.
