[$] Debating composefs

2 év 6 hónap óta
When LWN looked at the composefs filesystem in December, we reported that there had been "little response" to the patches. That is no longer the case. Whether composefs (or something like it) should be merged has become the subject of an extended debate; at its core, the discussion is over just how Linux should support certain types of container workloads.

[$] NASA and open-source software

2 év 6 hónap óta
From the moon landing to the James Webb Space Telescope and many other scientific missions, software is critical for the US National Aeronautics and Space Administration (NASA). Sharing information has also been in the DNA of the space agency from the beginning. As a result, NASA also contributes to and releases open-source software and open data. In a keynote at FOSDEM 2023, Science Data Officer Steve Crawford talked about NASA and open-source software, including the challenges NASA has faced in using open source and the agency's recent initiatives to lower barriers.

Axboe: io_uring and networking in 2023

2 év 6 hónap óta
Jens Axboe has posted a detailed guide to improving the performance of networking applications with io_uring.

Network applications have been written with a readiness type of model for decades, most commonly using epoll(2) these days to get notified when a given socket has data available. While these applications can be adapted to io_uring by swapping epoll notifiers with io_uring notifiers, going down that path does not lead to an outcome that fully takes advantage of what io_uring offers. It’ll potentially provide a reduction of system calls compared to epoll, but will not be able to take advantage of some of the other features that io_uring offers. To do that, a change to the IO event loop must be done.

Realtime Ubuntu launched

2 év 6 hónap óta
Canonical has announced the general availability of a realtime variant of its distribution.

Based on the 5.15 version of the Linux kernel, Ubuntu 22.04 LTS integrates the out-of-tree PREEMPT_RT patches for x86 and Arm architectures. The PREEMPT_RT patchset reduces the kernel latencies as required by the most exacting workloads, helping to ensure time-predictable task execution. Meeting stringent determinism requirements and upper-bounding execution time, Ubuntu with PREEMPT_RT makes the kernel more preemptive than mainline Linux.

Kiberbiztonsági keretrendszer jelent meg az ellátási láncokból eredő kockázatokhoz

2 év 6 hónap óta

Az OX Security februárban bejelentette az Open Software Supply Chain Attack Reference (OSC&R), az első és egyetlen nyílt keretrendszer bevezetését, amely a teljes ellátási lánc biztonságát veszélyeztető fenyegetések értékelésére és megértésére szolgál. A kezdeményezéshez többek között csatlakozott a Microsoft, a Google, a GitLab, a Check Point, az OWASP-, és a Fortinet jelenlegi és korábbi kiberbiztonsági vezetője is. […]

[$] An overview of single-purpose Linux distributions

2 év 6 hónap óta
Many people, when they are installing a Linux distribution for a single purpose such as running containers, would prefer an install-and-forget type of deployment. At FOSDEM 2023 in Brussels, several projects of this minimal Linux distribution type were presented. Fedora CoreOS, Ubuntu Core, openSUSE MicroOS, and Bottlerocket OS all tackle this problem in their own way. The talks at FOSDEM gave an interesting overview of how these projects differ in their approaches.

Two stable kernels — and maybe a third

2 év 6 hónap óta
The 6.1.12 and 5.15.94 stable kernel updates have been released, each with the usual set of important fixes. There is also a 5.10.168 release in the works, but it ran into some snags in the review process; it can be expected shortly.

Another set of updates, containing the mitigations for the just-disclosed cross-thread return-address prediction vulnerability (yet another Spectre variant that affects AMD processors), can be expected soon.

Ausztrália is száműzi a kínai biztonsági kamerákat a kormányzati épületekből

2 év 6 hónap óta

Az Ausztrál Védelmi Minisztérium a múlt héten bejelentette, hogy a kormányzati épületekben országszerte le fogják cserélni a kínai Hikvision és Dahua cégek által gyártott biztonsági kamerákat. Az indoklás szerint a gyártók túlságosan szoros kapcsolatban állnak a kínai állammal, ezért elővigyázatosságól eltávolítják az eszközöket.
