[$] Gccrs after libcore
Despite its increasing popularity, the Rust programming language is still
supported by a single compiler, the LLVM-based rustc. At the 2025 GNU Tools\
Cauldron, Pierre-Emmanuel Patry said that a lot of people are waiting
for a GCC-based Rust compiler before jumping into the language. Patry, who
is working on just that compiler (known as “gccrs”), provided an update on
the status of that project and what is coming next. ⌘ Read more

Next steps for BPF support in the GNU toolchain

[$] Next steps for BPF support in the GNU toolchain
Support for BPF in the kernel has been tied to the LLVM toolchain since the
advent of extended BPF. There has been a growing effort to add BPF support
to the GNU toolchain as well, though. At the 2025 GNU Tools Cauldron, the
developers involved got together with representatives of the kernel
community to talk about the state of that work and what needs to happen
next. ⌘ Read more

[$] Kernel hackers at Cauldron, 2025 edition
The GNU Tools Cauldron is almost entirely focused on user-space tools, but
kernel developers need a solid toolchain too. In what appears to be a
developing tradition ( started in 2024),
some kernel developers attended the 2025 Cauldron for the
second year in a row to discuss their needs with the assembled toolchain
developers. Topics covered in this year’s gathering include Rust, better

format (BTF … ⌘ Read more

Okay, now that I knew what to look for, I found existing bug reports:

• https://lists.gnu.org/archive/html/groff/2023-04/msg00400.html
  
• https://savannah.gnu.org/bugs/?63960
  

Most importantly:

This is resolved in the groff trunk.

🥳

@prologic@twtxt.net No, this is a Linux manpage from the man-pages project: https://git.kernel.org/pub/scm/docs/man-pages/man-pages.git/tree/man/man7/ascii.7

I do have an idea what’s going on. Could be an unfortunate interaction between the table preprocessor tbl and the man macro package. 🤔

@lyse@lyse.isobeef.org wouldn’t the PDF version be better? https://www.gnu.org/software/gawk/manual/gawk.pdf

Hmm, gnu.org is slow as heck. Shorter HTML pages load in about ten seconds. This complete AWK manual all in one large HTML page took a full minute: https://www.gnu.org/software/gawk/manual/gawk.html Is there maybe some anti AI shenanigans going on?

In any case, I find the user guide super interesting. My AWK skills are basically non-existent, so I finally decided to change that. This document is incredibly well written and makes it really fun to keep reading and learning. I’m very impressed. So far, I made it to section 1.6, happy to continue.

@prologic@twtxt.net Yes, this is another instance of restricting “personal” computing. You won’t be able to install arbitrary software anymore (“sideloading”, as they call it).

It’s not unique, it’s not new. Boiling the frog alive.

We’re heading towards this: https://www.gnu.org/philosophy/right-to-read.html

mandoc is nicer to read/write than the man macro package and, most importantly, it’s semantic markup.

HTML output is a bit broken in GNU groff, though (OpenBSD on the left, GNU on the right):

https://movq.de/v/f1898e648f/s.png

🤔

Still, I’m inclined to convert my manpages to mandoc.

Another example:

$ setpriv \
    --landlock-access fs \
    --landlock-rule path-beneath:execute,read-file:/bin/ls-static \
    --landlock-rule path-beneath:read-dir:/tmp \
    /bin/ls-static /tmp/tmp/xorg.atom

The first argument --landlock-access fs says that nothing is allowed.

--landlock-rule path-beneath:execute,read-file:/bin/ls-static says that reading and executing that file is allowed. It’s a statically linked ls program (not GNU ls).

--landlock-rule path-beneath:read-dir:/tmp says that reading the /tmp directory and everything below it is allowed.

The output of the ls-static program is this line:

─rw─r──r────x 3000 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

It was able to read the directory, see the file, do stat() on it and everything, the little x indicates that getting xattrs also worked.

3000 and 200 are user name and group name – they are shown as numeric, because the program does not have access to /etc/passwd and /etc/group.

Adding --landlock-rule path-beneath:read-file:/etc/passwd, for example, allows resolving users and yields this:

─rw─r──r────x cathy 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

glibc 堆內存管理：原理、機制與實戰
在內存管理領域，glibc（GNU C Library）通過 brk 和 mmap 兩大系統調用，構建了一套高效的堆內存管理機制。這種設計大幅減少了系統調用的頻次，顯著提升內存利用率。在 glibc 的管理架構中，堆內存以層級化的方式組織，包含分配區（Arena）、堆（Heap）和內存塊（Chunk）。其中，主 Arena 依賴 brk 系統調用實現內存分配，而子 Arena 則通過 mmap 完 ⌘ Read more

@shreyan@twtxt.net first time I’ve seen someone mention gnu taler. Been following it since it was announced:) never used for anything other then testing though.

Great, last system update broke something, building from current master I get:

What the heck!?
