Over the years, there has been steady progress in adding security features to
compilers and other tools to assist with hardening the Linux kernel (and, of course, other
programs). In something of a tradition in the toolchains
track at the Linux
Plumbers Conference, Kees Cook and Qing Zhao have led a session on that progress and
further plans; this year, they were joined by Justin Stitt (YouTube video).

Longtime Debian and Tor developer, Jérémy Bobbio—perhaps better known as
“Lunar”—died
on November 8. Lunar was one of the founders of the reproducible
builds movement and more recently had been working with Software Heritage. More
information and tributes in French can be found at this site. They will be missed.

The kernel graphics driver for the Apple M1 and M2 GPUs is, rather
famously, written in Rust, but it has achieved conformance with
various graphics standards, which is also noteworthy. At the X.Org Developers Conference
(XDC) 2024, Alyssa Rosenzweig gave an update on the status of the
driver, along with some news about the kinds of games it can support (YouTube video, slides).
There has been lots of progress since her talk at XDC last year (YouTube video),
with, of course, still more to come.

Rong Xu and
Han Shen described the kernel-optimization techniques that Google uses in the toolchains
track at the 2024 Linux
Plumbers Conference.
They talked about automatic
feedback-directed optimization (AutoFDO), which can be used with the Propeller
optimizer to produce kernels with better performance using profile
information gathered from real workloads. There is a fair amount of
overlap between these tools and the BOLT
post-link optimizer, which was the subject of a talk that directly preceded this session.

A pair of talks in the toolchains
track at the 2024 Linux
Plumbers Conference covered different tools that can be used to
optimize the kernel. First up was Maksim Panchenko to describe the binary
optimization and layout tool (BOLT) that Meta uses on its production
kernels. It optimizes the kernel binary by rearranging it to improve its
code locality for
better performance. A subsequent article will cover the second talk, which
looked at automatic
feedback-directed optimization (AutoFDO) and other related techniques
that are used to optimize Google’s kernels.

While Debian’s “sauce” is not actually all that secret, it is not particularly
well-known either, Samuel Henrique said at the start of his DebConf24 talk. There is a lot
of software-engineering effort that has been put in place by the
distribution in order to create and maintain its releases, but “loads of
” of it. That may be due to the fact that all of
people are not aware
that is
not really documented anywhere in a central location that he can just point
someone to. Recognizing that is what led him to give the talk;
hopefully it will be a “first step toward
” helping solve the problem.

Greg Kroah-Hartman has announced the release of the 6.11.3, 6.10.14, 6.6.55, and 6.6.56 stable kernels. The 6.6.56 release
fixes a problem with building perf in 6.6.55; “If you do not use the
“. Meanwhile,
perf tool in the 6.6.y tree, there is no need to upgrade.
6.10.14 is the last of the 6.10.y series, so users should now be moving to
6.11.y. Other than 6.6.56, they contain the usual long list of important
fixes throughout the kernel tree.
