Rocky Linux 8.4

Rocky Linux is a community enterprise operating system, created by Gregory Kurtzer, founder of the CentOS project. Rocky Linux 8.4 has been released for x86-64 and aarch64. "Sufficient testing has been performed such that we have confidence in its stability for production systems."

[$] A stable bug fix bites proprietary modules

The kernel-development community has long had a tense relationship with companies that create and ship proprietary loadable kernel modules. In the view of many developers, such modules are a violation of the GPL and should simply be disallowed. That has never happened, though; instead, the community has pursued a policy of legal ambiguity and...

Security updates for Monday

Security updates have been issued by Arch Linux (connman, go, and grub), Debian (nettle, prosody, and tor), Fedora (iaito, mingw-ilmbase, mingw-openexr, mingw-python-urllib3, mosquitto, nettle, polkit, and radare2), Mageia (puddletag, python-babel, python-eventlet, and python-pikepdf), openSUSE (htmldoc), SUSE (go1.15, go1.16, gupnp, and libgcrypt),...

Kernel prepatch 5.13-rc7

The 5.13-rc7 kernel prepatch is out for testing. "So there's not a huge number of patches in here, and most of the patches are pretty small too. A fair number of one-liners and 'few-liners'. Which is just how I like it." For reasons that have not been disclosed on the list, the codename for this release has been changed to "Opossums on Parade".

The 5.12.12, 5.10.45, and 5.4.127 stable kernels have been released. They contain important fixes, as usual, so users should upgrade.

[$] Protecting control dependencies with volatile_if()

Memory ordering issues are, as Linus Torvalds recently observed, "the rocket science of CS". Understanding memory ordering is increasingly necessary to write scalable code, so kernel developers often find themselves having to become rocket scientists. The subtleties associated with control dependencies turn out to be an especially tricky sort...

Security updates for Friday

Security updates have been issued by Arch Linux (aspnet-runtime, aspnet-runtime-3.1, chromium, drupal, intel-ucode, nginx, opera, python-django, radare2, thefuck, and vivaldi), Debian (jetty9), Fedora (dogtag-pki and pki-core), openSUSE (htmldoc and postgresql10), Oracle (dhcp), SUSE (apache2, caribou, jetty-minimal, libxml2, postgresql12, python-PyJWT,...

[$] Landlock (finally) sets sail

Kernel development is not for people who lack persistence; changes can take a number of revisions and a lot of time to make it into a mainline release. Even so, the story of the Landlock security module, developed by Mickaël Salaün, seems like an extreme case; this code was merged for 5.13 after more than five years of development and 34 versions...

Supporting Miguel Ojeda’s Work on Rust in the Linux Kernel (Prossimo blog)

The Prossimo project has announced that it has contracted with Miguel Ojeda to work on Rust in the Linux kernel for the next year. Prossimo is a new name for the memory-safety projects being run by the Internet Security Research Group (ISRG), which is the organization behind the Let's Encrypt certificate authority (CA) project. Google provided...
