Debian Votes to Issue No Statement on Stallman's Return to the FSF Board
Posted: 2021-04-18 17:34:00 Source: http://rss.slashdot.org/~r/Slashdot/slashdotLinuxatom/~3/EOO9282wCIQ/debian-votes-to-issue-no-statement-on-stallmans-return-to-the-fsf-board
An anonymous reader writes: Debian Project Secretary Kurt Roeckx has announced the results of a closely-watched vote on what statement would be made about Richard Stallman's readmission to the Free Software Foundation's board. Seven options were considered, with the Debian project's 420 voting developers also asked to rank their preferred outcomes: Option 1: "Call for the FSF board removal, as in rms-open-letter.github.io" Option 2: "Call for Stallman's resignation from all FSF bodies" Option 3: "Discourage collaboration with the FSF while Stallman is in a leading position" Option 4: "Call on the FSF to further its governance processes" Option 5: "Support Stallman's reinstatement, as in rms-support-letter.github.io" Option 6: "Denounce the witch-hunt against RMS and the FSF" Option 7: "Debian will not issue a public statement on this issue" While all seven options achieved a quorum of votes, two failed to achieve a majority — options 5 and 6. ("Support Stallman's reinstatement" and "Denounce the witch-hunt...") The option receiving the most votes was #7 (not issuing a public statement) — but it wasn't that simple. The vote's final outcome was determined by comparing every possible pair of options to determine which option would still be preferred by a majority of voters in each possible comparision. In this case, that winner was still the option which had also received the most votes: Debian will not issue a public statement on this issue. The Debian Project will not issue a public statement on whether Richard Stallman should be removed from leadership positions or not. Any individual (including Debian members) wishing to (co-)sign any of the open letters on this subject is invited to do this in a personal capacity. The results are captured in an elaborate graph. Numbers inside the ovals show the final ratio of yes to no votes (so a number higher than 1.00 indicates a majority, with much higher numbers indicating much larger majorities). Numbers outside the ovals (along the lines) indicate the number of voters who'd preferred the winning choice over the losing choice (toward which the arrow is pointing). The winning option is highlighted in blue.

Openwall Releases 'Linux Kernel Runtime Guard' 0.9.0
Posted: 2021-04-18 14:34:00 Source: http://rss.slashdot.org/~r/Slashdot/slashdotLinuxatom/~3/ICCP3R3X8Lc/openwall-releases-linux-kernel-runtime-guard-090
Long-time Slashdot reader xiando shares news from LinuxReviews: Linux Kernel Runtime Guard (LKRG) is a security module for the Linux kernel developed by Openwall. The latest release adds compatibility with Linux kernels up to soon to be released 5.12, support for building LKRG into kernel images, support for old 32-bit x86 machines and more... The Linux Kernel Runtime Guard is an out-of-tree kernel module you can install as a kernel module, or, with the 0.9.0 release, build into your Linux kernel. It does run-time integrity checks to detect security vulnerability exploits against the Linux kernel. An Openwall developer also notes in the announcement that "During LKRG development and testing I've found 7 Linux kernel bugs, 4 of them have CVE numbers."

Slackware Approaches 28th Birthday With New Beta Release
Posted: 2021-04-18 01:34:00 Source: http://rss.slashdot.org/~r/Slashdot/slashdotLinuxatom/~3/eMXRsqyzkCE/slackware-approaches-28th-birthday-with-new-beta-release
Slashdot reader LeeLynx shares news from The Register about a Slackware 15 beta release (following the debut of February's alpha), "nearly five years after the distribution last saw a major update." (And nearly 28 years after its initial release back in 1993...) Created by Patrick Volkerding (who still lays claim to the title Benevolent Dictator For Life), the current release version arrived in the form of 2016's 14.2... The Linux kernel has been updated to 5.10.30 (at time of writing) with 5.11.14 available for testing. Desktop fans may be pleased to see, among the many updates, KDE Plasma hitting 5.21.4 as well as updates for old faithfuls, such as Mozilla Firefox and Thunderbird. The beta itself dropped on 12 April (with the 5.10.29 kernel) and Volkerding noted: "I'm going to go ahead and call this a beta even though there's still no fix for the illegal instruction issue with 32-bit mariadb. But there should be soon." Tinkering has continued since, judging by the change log, although the beta tag brings hope there will be a release before long.

Linus Torvalds Says Rust Closer for Linux Kernel Development, Calls C++ 'A Crap Language'
Posted: 2021-04-17 17:34:00 Source: http://rss.slashdot.org/~r/Slashdot/slashdotLinuxatom/~3/-2qN164bmqM/linus-torvalds-says-rust-closer-for-linux-kernel-development-calls-c-a-crap-language
Google's Android team supports Rust for developing the Android operating system. Now they're also helping evaluate Rust for Linux kernel development. Their hopes, among other things, are that "New code written in Rust has a reduced risk of memory safety bugs, data races and logic bugs overall," that "abstractions that are easier to reason about," and "More people get involved overall in developing the kernel, thanks to the usage of a modern language." Linus Torvalds responded in a new interview with IT Wire (shared by Slashdot reader juul_advocate): The first patches for Rust support in the Linux kernel have been posted and the man behind the kernel says the fact that these are being discussed is much more important than a long post by Google about the language. Linus Torvalds told iTWire in response to queries that Rust support was "not there yet", adding that things were "getting to the point where maybe it might be mergeable for 5.14 or something like that..." Torvalds said that it was still early days for Rust support, "but at least it's in a 'this kind of works, there's an example, we can build on it'." Asked about a suggestion by a commenter on the Linux Weekly News website, who said, during a discussion on the Google post, "The solution here is simple: just use C++ instead of Rust", Torvalds could not restrain himself from chortling. "LOL," was his response. "C++ solves _none_ of the C issues, and only makes things worse. It really is a crap language. "For people who don't like C, go to a language that actually offers you something worthwhile. Like languages with memory safety and [which] can avoid some of the dangers of C, or languages that have internal GC [garbage collection] support and make memory management easier. C++ solves all the wrong problems, and anybody who says 'rewrite the kernel in C++' is too ignorant to even know that." He said that when one spoke of the dangers of C, one was also speaking about part of what made C so powerful, "and allows you to implement all those low-level things efficiently". Torvalds added that, while garbage collection is "a very good thing in most other situations," it's "generally not necessarily something you can do in a low-level system programming."
