  RE: https://mastodon.social/@FEX_Emu/117289845632972172 ""We’re going to cover an ongoing problem with x86 emulation that affects every application that we emulate. This comes down to a single over-arching term that has wide-reaching ramifications; Emulating the x86 Total Store Ordering memory model (x86-TSO). The problems with emulating this memory model on the weak ordering memory model that ARM defines is multi-faceted and covers multiple issues. We’re going to go over all the pro...

  In case #Linux 7.2, v7.1.9+, or v6.18.45+ broke Bluetooth for you, then it's likely the following known problem in case you have a Realtek RTL8761B/BU BT chip: * https://lore.kernel.org/all/20260822141115.58815-1-kserwus@gmail.com/ * https://lore.kernel.org/all/20260823102959.100368-1-kserwus@gmail.com/ * https://lore.kernel.org/all/20260824053227.317496-1-junjie.cao@intel.com/ * https://bugzilla.redhat.com/show_bug.cgi?id=2521504 #LinuxKernel #kernel

  Linus once more states that AI is just a tool: https://lore.kernel.org/all/CAHk-%3Dwi4zC%2BZe8e%2Bp3tMv8TtG_80KzsZ1syL9anBtmEh5Z40vg@mail.gmail.com/ "" #Linux [the #kernel] is not one of those anti-AI projects, and if somebody has issues with that, they can do the open-source thing and fork it. Or just walk away. AI is a tool, just like other tools we use. And it's clearly a useful one. It may not have been that "clearly" even just a year ago, but it's no longer...

  "[…] The "#CopyFail" vulnerability presented a unique challenge for us. Despite our practice of deploying #Linux patch updates every two weeks, we remained vulnerable because a month-old mainline fix had yet to be backported to our primary #kernel line. Despite that, we were still able to roll out patched kernels within hours of the backport's release. In the interim, #bpf-lsm provided a surgical, no-reboot mitigation that secured our fleet.

  [Edit] You might want to ignore this post! Seems the tags were an accident and were already removed in Linus' repo (but they might have ended up in your local mirror if you are unlucky; using the "--prune-tags" option of git fetch might be what you want then, but be careful, it might remove tags you care about). [/edit] Wondering why there are suddenly git tags for every downstream merge Linus performs for #Linux 7.2 (which will lead to a lot of tag noise I guess)....

  Quick reminder in light of the recent #LinuxKernel vulnerabilities: In case you want to protect yourself against vulnerabilities in #Linux #Kernel modules you don't need, disable module loading completely by running: echo 1 | sudo tee /proc/sys/kernel/modules_disabled Of course you want to load all modules you need before running that command, as otherwise you will have to reboot to load them. 😄 More details on this: * https://dfir.ch/posts/today_i_learned_lkm_kernel.modules_disabl...

  RE: https://hachyderm.io/@kernellogger/116419722474231366 A fix for the #kernel stuttering/periodic lockups problem mentioned below[1] now has hit #Linux mainline: https://git.kernel.org/torvalds/c/4096fd0e8eaea13ebe5206700b33f49635ae18e5 Now it needs a backport to 7.0, as it does not apply cleanly there.

  Quick reminder wrt removing features or drivers from the #Linux #kernel, like currently considered in the networking subsystem and a few other areas[1]: The "no regressions" rule still applies – so nothing people still use should be removed (or the removal should be reverted in case it turns out people still use it). This is why the network drivers 3c59x and xirc2ps, MVME147 that were on the chopping board will remain[2]. But there are a few caveats, some of them: * &q...

  From David Malcolm, who among others mentioned: * GCC error messages have a hierarchical structure to them. In GCC 15, I added an experimental option that shows this structure as a collection of nested bullet points. In GCC 16, this behavior is now the default. * GCC 16 includes several improvements to the generated SARIF output. * In GCC 15, I added -fdiagnostics-add-output= to allow for multiple kinds of diagnostic output simultaneously. Plain text output has limitations, so GCC 16 inclu...

  Reminder[1]: Now is the best[2] time to test the #kernel to prevent #LinuxKernel regressions from hitting #ArchLinux, #Fedora Linux, or #openSUSE #Tumbleweed. That's because the first pre-release (aka "-rc1") of #Linux 7.1 is out – which leaves plenty of time to find, report, debug, and fix any problems that those distros otherwise will encounter when they switch to 7.1.y in about eight to ten weeks. And testing is not even hard, as easy-to-install packages with pre-bu...
