[$] Tools for kernel developers

9 hónap 3 hét óta
Konstantin Ryabitsev started a session on development tooling at the 2024 Maintainers Summit by saying that he does not want to be a "wrecking ball". If a given workflow is working for people, he does not want to try to force any sort of change. That said, he has ideas for how he can continue his work on providing better tooling for the development community.

Linux Plumbers Conference: That’s a wrap! Thanks everyone for Linux Plumbers 2024

9 hónap 3 hét óta

Thank you to everyone who attended Linux Plumbers 2024 both in person and virtually!

This year we were able to accommodate huge demand for in-person participation and we were glad to see more than 700 people in the Austria Center.
As in previous years after the pandemic we also had a virtual component with more than 200 participants.

We had a lot of great content in Refereed Track, Kernel Summit, eBPF and Networking Summits and Toolchains Track and a lot of productive discussions in 24 microconferences.

There also were 25 Birds-of-a-Feather sessions, many of them were added during the event to continue a discussion that started in a microconference or in the Hallway Track.

There are recordings of live streams and we hope to have recordings of all the sessions soon.

Finally, I want to thank all those that were involved in making Linux Plumbers the best technical conference there is. This would not have happened without the hard work from the planning committee (Alice Ferrazzi, André Almeida, Christian Brauner, David Woodhouse, James Bottomley, Kate Stewart, Lorenzo Pieralisi, Shuah Khan, Song Liu, Steve Rostedt, Tim Bird), the runners of the Networking and BPF Summit tracks, the Toolchain track, Kernel Summit, and those that put together the very productive microconferences. I would also like to thank all those that presented as well as those who attended both in-person and virtually.

I want to thank our sponsors for their continued support, without them Linux Plumbers Conference would not be possible.

And a very special thanks to the Linux Foundation and their staff who did really great job behind the scenes and on-site to make this conference run smoothly. Their work is greatly appreciated by the LPC planning committee.

Sincerely,

Mike Rapoport
Linux Plumbers 2024 Conference chair

pcp: pmcd network daemon review (SUSE Security Team Blog)

9 hónap 4 hét óta

The SUSE Security Team Blog has a detailed review of the Performance Co-Pilot (PCP) 6.2.1 release:

The rather complex PCP software suite was difficult to judge just from a cursory look, so we decided to take a closer look especially at PCP's networking logic at a later time. This report contains two CVEs and some non-CVE related findings we also gathered during the follow-up review.

CVE-2024-45769, a flaw that could allow an attacker to send crafted data to crash pcmd, and CVE-2024-45770, which could allow a full local root exploit from the pcp user to root, have been addressed in the 6.3.1 release of PCP.

[$] The 6.12 merge window begins

9 hónap 4 hét óta
As of this writing, 6,778 non-merge changesets have been pulled into the mainline kernel for the 6.12 release — over half of the work that had been staged in linux-next prior to the opening of the merge window. There has been a lot of refactoring and cleanup work this time around, but also some significant changes. Read on for a summary of the first half of the 6.12 merge window.

OpenSSH 9.9 released

9 hónap 4 hét óta

The OpenSSH project has released version 9.9. This version includes support for the new post-quantum cryptography standard from NIST. The release also includes the next step in the deprecation of DSA keys — they are now disabled by default at compile time, and are expected to be removed entirely in early 2025. The release also contains the normal mixture of bug fixes and small usability improvements.

[$] Considering kernel pass-through interfaces

9 hónap 4 hét óta
The kernel normally sits firmly between user space and the system's peripheral devices, and provides a standard interface to those devices. At times, though, a more direct interface to a device is desired — but such interfaces can be controversial. At the 2024 Maintainers Summit, the assembled developers considered a specific case — the proposed fwctl subsystem — as well as the role of such drivers in general.

The realtime preemption pull request

9 hónap 4 hét óta
On September 19, Thomas Gleixner delivered the pull request for the realtime preemption enablement patches to Linus Torvalds — in printed form, wrapped in gold, with a ribbon, as Torvalds had requested. It was a significant milestone, marking the completion of a project that required 20 years of effort. Congratulations are due to everybody involved.

Torvalds acted on the pull request the following morning.
