LineageOS 17.1 released

5 év 3 hónap óta
LineageOS 17.1 is out. This release of the Android-based distribution once known as CyanogenMod includes a rebase onto the Android 10 release of the Android Open Source Project, improved theme support, support for on-screen fingerprint sensors, the ability to use biometric sensors to control access to apps, and more. "On the whole, we feel that the 17.1 branch has reached feature and stability parity with 16.0 and is ready for initial release. With 17.1 being the most recent and most actively developed branch, on April 1st, 2020 it will begin receiving nightly builds and 16.0 will be moved to weekly builds."

[$] Reworking StringIO concatenation in Python

5 év 3 hónap óta
Python string objects are immutable, so changing the value of a string requires that a new string object be created with the new value. That is fairly well-understood within the community, but there are some "anti-patterns" that arise; it is pretty common for new users to build up a longer string by repeatedly concatenating to the end of the "same" string. The performance penalty for doing that could be avoided by switching to a type that is geared toward incremental updates, but Python 3 has already optimized the penalty away for regular strings. A recent thread on the python-ideas mailing list explored this topic some.

[$] Three candidates vying to be DPL

5 év 3 hónap óta
The annual Debian project leader (DPL) election is well underway at this point; voting begins in early April and the outcome will be known after the polls close on April 18. Outgoing DPL Sam Hartman posted a lengthy "non-platform" in the run-up to the election, which detailed the highs and lows of his term, perhaps providing something of a roadmap, complete with pitfalls, for potential candidates—Hartman is not running again this time. When the nomination period completed, three people put their hats into the ring: Jonathan Carter, Sruthi Chandran, and Brian Gupta. Their platforms have been posted and there have been several threads on the debian-vote mailing list with questions for the candidates; it seems like a good time to look in on the race.

OpenWRT code-execution bug puts millions of devices at risk (Ars Technica)

5 év 3 hónap óta
Ars Technica reports on the recently disclosed OpenWrt package verification vulnerability. The headline may be a bit overwrought, though. "These code-execution exploits are limited in their scope because adversaries must either be in a position to conduct a man-in-the-middle attack or tamper with the DNS server that a device uses to find the update on the Internet. That means routers on a network that has no malicious users and using a legitimate DNS server are safe from attack." It also assumes that people actually update their routers, which seems unlikely in most cases in the real world.

FSF: HACKERS and HOSPITALS

5 év 3 hónap óta
The Free Software Foundation is focusing on the shortage of medical equipment and using 3D printers to make more. "That's why we're looking into what we can make with our in-office Respects Your Freedom (RYF)-certified 3D printers, and we're talking to the brand new Mass General Brigham Center for COVID Innovation so they can direct our efforts. We're also gathering resources for our "HACKERS and HOSPITALS" plan at the LibrePlanet wiki page, and if you have expertise, 3D printers, or supplies to contribute, please contact Michael via sysadmin@fsf.org. If you do not have the means to produce medical gear and you still want to help, research can be done from anywhere with only a computer and an Internet connection. Add any projects that are freely licensed working towards helping with COVID-19 to the wiki!"

MOSS launches COVID-19 Solutions Fund

5 év 3 hónap óta
The Mozilla Open Source Support Program (MOSS) has launched a COVID-19 Solutions Fund, which will provide awards of up to $50,000 each to open source technology projects which are responding to the COVID-19 pandemic in some way. "As part of the COVID-19 Solutions Fund, we will accept applications that are hardware (e.g., an open source ventilator), software (e.g., a platform that connects hospitals with people who have 3D printers who can print parts for that open source ventilator), as well as software that solves for secondary effects of COVID-19 (e.g., a browser plugin that combats COVID related misinformation)."

Unangst: Rethinking OpenBSD security

5 év 3 hónap óta
OpenBSD developer Ted Unangst looks for lessons in a set of recent vulnerabilities in that system. "Even OpenBSD is subject to compromise for the sake of practicality, which is how some legacy designs stick around. So the lesson perhaps is to really stick with the principles that work, and not just when convenient. But not always an easy choice to make."

[$] Some 5.6 kernel development statistics

5 év 3 hónap óta
When the 5.6 kernel was released on March 29, 12,665 non-merge changesets had been accepted from 1,712 developers, making this a fairly typical development cycle in a number of ways. As per longstanding LWN tradition, what follows is a look at where those changesets came from and who supported the work that created them. This may have been an ordinary cycle, but there are still a couple of differences worth noting.

Fedora's Git forge decision

5 év 3 hónap óta
Back in February, LWN reported on the process of gathering requirements for a Git forge system. That process then went relatively quiet until March 28, when the posting of a "CPE Weekly" news summary included, under "other updates", a note that the decision has been made. It appears that the project will be pushed toward a not-fully-free version of the GitLab offering. It is fair to say that this decision — or how it was presented — was not met with universal acclaim in the Fedora community; see this response from Neal Gompa for more.

Debian @ COVID-19 Biohackathon (April 5-11, 2020)

5 év 3 hónap óta
The Debian community has announced a one-week, online "biohackathon" as a focused effort to improve the available free biomedical tools. "Most tasks do not require any knowledge of biology or medicine, and all types of contributions are welcome: bug triage, testing, documentation, CI, translations, packaging, and code contributions."

The 5.6 kernel has been released

5 év 3 hónap óta
Linus has released the 5.6 kernel.

Some of the headline features in this release include Arm EOPD support, time namespaces, the BPF dispatcher and batched BPF map operations (both described in this article), the openat2() system call, the WireGuard virtual private network implementation, the flow queue PIE packet scheduler, nearly complete year-2038 support, many new io_uring features, the pidfd_getfd() system call, the ZoneFS filesystem, the ability to implement TCP congestion-control algorithms in BPF, the dma-buf heaps subsystem, and the removal of the /dev/random blocking pool.

See the LWN merge-window summaries (part 1 and part 2) and the (under construction) KernelNewbies 5.6 page for more details.

[$] Per-system-call kernel-stack offset randomization

5 év 3 hónap óta
In recent years, the kernel has (finally) upped its game when it comes to hardening. It is rather harder to compromise a running kernel than it used to be. But "rather harder" is relative: attackers still manage to find ways to exploit kernel bugs. One piece of information that can be helpful to attackers is the location of the kernel stack; this patch set from Kees Cook and Elena Reshetova may soon make that information harder to come by and nearly useless in any case.
