[$] Securing Git repositories with gittuf

[Security] Posted May 8, 2024 16:11 UTC (Wed) by jzb

The so-called software supply chain starts with source code. But most security measures and toolingdon't kick in until source is turned into an artifact—a sourcetarball, binary build, container image, or other method of delivering arelease to users. The gittuf projectis an attempt to provide a security layer for Git that can handle key management,enforce security policies for repositories, and guard against attacksat the version-control layer. At Open Source Summit North America (OSSNA), Aditya Sirish AYelgundhalli and Billy Lynch presentedan introduction to gittuf with an overview of its goals andstatus.

[$] A proposal to switch Fedora Workstation's desktop

[Distributions] Posted May 7, 2024 21:46 UTC (Tue) by jake

A proposal to switch the default desktop for Fedora Workstation from GNOMEto KDE Plasma largely went over like the proverbial lead balloon—unsurprisingly.But the conversation about the proposal did surface some areas where thedistribution could perhaps be more inclusive with regard to the other desktop choicesavailable. The project believes that itbenefits from being opinionated and not requiring users to makemultiple decisions before they can even install the distribution, but thereis a balance to be found.

Secure Randomness in Go 1.22 (Go Blog)

[Development] Posted May 7, 2024 12:46 UTC (Tue) by corbet

The Go Blog has a detailedarticle on the new, more secure random-number generator implemented forthe 1.22 release.

For example, when Go 1.20 deprecated math/rand's Read, we heardfrom developers who discovered (thanks to tooling pointing out useof deprecated functionality) they had been using it in places wherecrypto/rand's Read was definitely needed, like generating keymaterial. Using Go 1.20, that mistake is a serious security problemthat merits a detailed investigation to understand thedamage. Where were the keys used? How were the keys exposed? Wereother random outputs exposed that might allow an attacker to derivethe keys? And so on. Using Go 1.22, that mistake is just a mistake.

Stenberg: I survived curl up 2024

[Briefs] Posted May 6, 2024 20:14 UTC (Mon) by daroc

Daniel Stenberg hasposted a report about the recent curl up conference about curl development. It was held over two days inStockholm. The report has short summaries of the talks with links to therecordings.

curl up is never a big meeting/conference but we have in the pastsometimes been around twenty-five attendees. This year's amount offifteen was the smallest so far, but in this small set of people wehave a set of long-term well-known curl contributors. It is not abig list of attendees that creates a good curl up.

[$] Inheritable credentials for directory file descriptors

[Kernel] Posted May 2, 2024 15:10 UTC (Thu) by corbet

In Unix-like systems, an open file descriptor carries the right to accessthe opened object in specific ways. As a general rule, that filedescriptor does not enable access to any other objects. Therecently merged BPF token feature runscounter to this practice by creating file descriptors that carry specificBPF-related access rights. A similar but different approach tocapability-carrying file descriptors, in the form of directory filedescriptors that include their own credentials, is currently underconsideration in the kernel community.
