Heise interviews Miguel Ojeda about the Rust-for-Linux project.

The first drivers (and the abstractions supporting them) that will start to be upstreamed are likely to be the Asahi Linux's GPU driver, Android's Binder and the NVMe driver. These are all non-trivial and will set the example for future Rust kernel abstractions and drivers.

The 6.3-rc1 kernel prepatch is out, and the merge window is closed for this development cycle.

And of course, smooth or not, now that the merge window is closed, we need to make sure it all *works*. We had a couple of exciting merges already, and I think the fallout from that got sorted out, but I'm sure there's more to come. Let's hope the calming-down period of 6.3 works as well as the merge window did... Knock wood.

It's that time of the year again. With this commit, Theo de Raadt (deraadt@) changed the version string for the development branch of OpenBSD to 7.3-beta.

The commit reads,

On March 7, 2003, a struggling company called The SCO Group filed a lawsuit against IBM, claiming that the success of Linux was the result of a theft of SCO's technology. Two decades later, it is easy to look back on that incident as a somewhat humorous side-story in the development of Linux. At the time, though, it shook our community to its foundations. It is hard to overestimate how much the community we find ourselves in now was shaped by a ridiculous lawsuit 20 years ago.

Thorsten Kukuk demonstrates that we are not done with year-2038 problems yet.

The general statement so far has always been that on 64bit systems with a 64bit time_t you are safe with respect to the Y2038 problem. But glibc uses for compatibility with 32bit userland applications 32bit time_t in some places even on 64bit systems.

One of those places is the utmp file. The post includes a proposal for solving the problem by getting rid of utmp entirely.

Greg Kroah-Hartman has announced the release of the 6.2.2, 6.1.15, 5.15.97, 5.10.171, 5.4.234, and 4.19.275 stable kernels. All contain a relatively small number of important fixes.

Update: 5.15.98 and 5.10.172 have subsequently been released with an io_uring fix.

Security updates have been issued by Debian (linux-5.10 and node-css-what), SUSE (gnutls, google-guest-agent, google-osconfig-agent, nodejs10, nodejs14, nodejs16, opera, pkgconf, python-cryptography, python-cryptography-vectors, rubygem-activesupport-4_2, thunderbird, and tpm2-0-tss), and Ubuntu (git, kernel, linux, linux-aws, linux-aws-5.15, linux-azure, linux-azure-5.15, linux-azure-fde, linux-gcp, linux-gcp-5.15, linux-gke, linux-gke-5.15, linux-hwe-5.15, linux-lowlatency, linux-lowlatency-hwe-5.15, linux-oracle, linux-oracle-5.15, linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.19, linux-ibm, linux-lowlatency, linux-oracle, linux-azure-fde, linux-oem-5.14, linux-oem-5.17, linux-oem-6.0, linux-oem-6.1, php7.0, python-pip, ruby-rack, spip, and sudo).

Az amerikai kiberbiztonsági és infrastruktúra-biztonsági ügynökség (CISA) hozzáadta a CVE-2022-36537 azonosító alatt jegyzett sebezhetőséget a "Known Exploited Vulnerabilities Catalog" listájához, miután a kiberbűnözők aktívan elkezdték kihasználni a hibát távoli kódfuttatásra (RCE).

The post A ZK Java Framework kritikus hibájára figyelmeztet a CISA first appeared on Nemzeti Kibervédelmi Intézet.

While the 6.3 kernel has gained more support for the Rust language, it still remains true that there is little that can be done in Rust beyond the creation of a "hello world" module. That functionality was already available in C, of course, with a level of safety similar to what Rust can provide. Interest is growing, though, in merging actually useful modules written in Rust; that will require some more capable infrastructure than is currently present. A recent discussion on the handling of time values in Rust demonstrates the challenges — and opportunities — inherent in this effort.

Security updates have been issued by CentOS (git), Debian (spip), Fedora (epiphany), Mageia (binwalk, chromium-browser-stable, crmsh, emacs, libraw, libtiff, nodejs, pkgconf, tar, and vim), Oracle (kernel and systemd), SUSE (emacs, kernel, nrpe, and rubygem-activerecord-4_2), and Ubuntu (c-ares, git, postgresql-12, postgresql-14, and sox).

The LWN.net Weekly Edition for March 2, 2023 is available.

The Python-packaging discussions continued in January and February; they show no sign of abating in March either. This time around, we look (again) at tools for packaging, including a brand new Rust-based entrant. There is also a proposal to have interested parties create Python Enhancement Proposals (PEPs) for packaging solutions that would be judged by a panel of PEP delegates in order to try to choose something that the whole community can rally around—without precluding the existence of other options. As always, it is all a difficult balancing act.

Konstantin Ryabitsev has a request for anybody who is using mutt for kernel work:

At some point in the recent past, mutt changed the way it generates Message-ID header values. Instead of the perfectly good old way of doing it, the developers switched to using base64-encoded random bytes. The base64 dictionary contains the / character, which causes unnecessary difficulties when linking to these messages on lore.kernel.org, since the / character needs to be escaped as %2F for everything to work properly.

The post includes a simple workaround for the problem.

The waiting is done; version 4.0 of the Godot game engine has been released.

4 years of development. 12,000 merged pull requests. 7,000 fixed issues. 1,500 individual contributors across engine and docs.

The Godot 4.0 release is by all metrics our biggest release so far. No stone has been left unturned, all parts of the engine have been modernized, refactored, overhauled, rewritten, redesigned.

See the release notes for more information.

Security updates have been issued by Debian (multipath-tools and syslog-ng), Fedora (gnutls and guile-gnutls), Oracle (git, httpd, lua, openssl, php, python-setuptools, python3.9, sudo, tar, and vim), Red Hat (kpatch-patch), Scientific Linux (git), SUSE (compat-openssl098, glibc, openssl, postgresql13, python-Django, webkit2gtk3, and xterm), and Ubuntu (awstats, expat, firefox, gnutls28, lighttpd, php7.2, php7.4, php8.1, python-pip, and tar).

At USENIX SREcon22 APAC I gave the opening keynote on the future of computer performance, rounding up the latest developments and making predictions of where I see things heading. This talk originated from my updates to [Systems Performance 2nd Edition], and this was the first time I've given this talk in person! The video is now on [YouTube]:

The slides are [online] and as a [PDF]: first prev next last / permalink/zoom In Q&A I was asked about CXL (compute express link) which was fortunate as I had planned to cover it and then forgot, so the question let me talk about it (although Q&A is missing from the video). CXL in a way allows a custom memory controller to be added to a system, to increase memory capacity, bandwidth, and overall performance. My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. So it's interesting, but I don't think they have the killer use case for it yet. ## Realizing and exceeding a lifelong dream I began my tech career as a junior Unix sysadmin in Newcastle, NSW, Australia, in 1999, with no connection to the exciting world of tech in Silicon Valley, New York, or even nearby Sydney. As I was determined to become great at my new occupation regardless of my location, I read every sysadmin book, article, and magazine I could find on the shelf. This included SysAdmin magazine, which contained articles from various experts including Amy Rich, and a couple of advertisements: One was to submit your own articles to the magazine for publication (by writing to the editor, Rikki Endsley) and another was to attend USENIX conferences in the US and learn directly from the experts! I made both of these my goals, even though I'd never been published before and I'd never been to the US. Or even on a plane. I didn't end up getting published in SysAdmin directly, but my performance work did make it as a feature article (thanks Matty). As for attending USENIX conferences: I finally started attending and speaking at them in 2010 when a community manager encouraged me to (thanks Deirdre Straughan), and since then I've met many friends and connections, including Amy who is now USENIX President, and Rikki with whom I co-chaired the USENIX LISA18 conference. USENIX has been a great help to my career and my employers, and I hope it is just as helpful for you. It's an important vendor-neutral space to share the latest in technology. And now, helping bring USENIX conferences to Australia by giving the first keynote: I could not have scripted or expected it. It was a great privilege. ## SREcon 2023 CFP Tech moves fast, however, and I have little time to reflect on 2022 when there's 2023 to plan! I'm now program co-chair for SREcon 2023 APAC, and our 2023 conference is June 14-16 in Singapore. The call for participation ends on March 2nd 23:59 SGT! That's about 24 hours from now! ## References I've reproduced the references from my SREcon22 keynote below, so you can click on links: - [Gregg 08] Brendan Gregg, “ZFS L2ARC,” http://www.brendangregg.com/blog/2008-07-22/zfs-l2arc.html, Jul 2008 - [Gregg 10] Brendan Gregg, “Visualizations for Performance Analysis (and More),” https://www.usenix.org/conference/lisa10/visualizations-performance-analysis-and-more, 2010 - [Greenberg 11] Marc Greenberg, “DDR4: Double the speed, double the latency?
