There are several main categories into which kernel releases may fall: Prepatch Prepatch or "RC" kernels are mainline kernel pre-releases that are mostly aimed at other kernel developers and Linux enthusiasts. They must be compiled from source and usually contain new features that must be tested before they can be …

Most of them include a full archive of messages going back several decades. listing of currently hosted archives If you would like to suggest another kernel development mailing list to be included in this list …
We'd like to announce several small changes to the way Linux tarballs are produced. Mainline release tarball signatures Starting with the 4.18 final release, all mainline tarball PGP signatures will be made by Greg Kroah-Hartman instead of Linus Torvalds. The main goal behind this change is to simplify the …
If you are in charge of CI infrastructure that needs to perform frequent full clones of kernel trees from git.kernel.org, we strongly recommend that you use the git bundles we provide instead of performing a full clone directly from git repositories. It is better for you, because downloading …
The Linux Foundation IT team has been working to improve the code integrity of git repositories hosted at kernel.org by promoting the use of PGP-signed git tags and commits. Doing so allows anyone to easily verify that git repositories have not been altered or tampered with no matter from …
All kernel releases are cryptographically signed using OpenPGP-compliant signatures. Everyone is strongly encouraged to verify the integrity of downloaded kernel releases by verifying the corresponding signatures. Basic concepts Every kernel release comes with a cryptographic signature from the person making the release. This cryptographic signature allows anyone to verify whether …
As you may be aware, starting with 4.12-rc1 Linus will no longer provide signed tarballs and patches for pre-release ("-rc") kernels. Reasons for this are multiple, but largely this is because people who are most interested in pre-release tags -- kernel developers -- do not rely on patches and tarballs to …
The XZ tarballs for the following kernel releases did not initially pass signature verification due to benign changes to the tarball structure done by the pixz compression tool: 4.11.1 4.10.16 4.9.28 4.4.68 These changes would have resulted in GPG returning "Bad Signature …
We are extremely happy to announce that Packet has graciously donated the new hardware systems providing read-only public access to the kernel.org git repositories and the public website (git.kernel.org and www.kernel.org, respectively). We have avoided using cloud providers in the past due to security implications …
Those of you who have been around for a while may remember a time when you used to be able to mount kernel.org directly as a partition on your system using NFS (or even SMB/CIFS). The Wayback Machine shows that this was still advertised some time in January …
If your browser alerted you that the site certificates have changed, that would be because we replaced our StartCOM, Ltd certificates with those offered by our DNS registrar, Gandi . We are very thankful to Gandi for this opportunity. A common question is why we aren't using the certificates offered by …
If you find yourself on an unreliable Internet connection and need to perform a fresh clone of Linux.git, you may find it tricky to do so if your connection resets before you are able to complete the clone. There is currently no way to resume a git clone using …
We are happy to announce that Fastly has offered their worldwide CDN network to provide fast download services for Linux kernel releases, which should improve download speeds for those of you located outside North America. We have modified the front page to offer CDN-powered download links, but all the existing …
Linus named the upcoming 4.0 release of the kernel "Hurr Durr I'ma Sheep" (see his git commit ), so we are celebrating this April Fool's day with a minor prank. If you've been redirected to imasheep.hurrdurr.org , do not panic. It's all part of the joke. We've also restored …
We've had to temporarily limit FTP access to mirrors.kernel.org due to high IO load. We have recently upgraded our hardware in order to increase capacity -- 16TB was no longer nearly sufficient enough to host all the distro mirrors and archives. We chose larger but slower disks and offset …
Since we rely on the OpenSSL library for serving most of our websites, we, together with most of the rest of the open-source world, were vulnerable to the HeartBleed vulnerability. We have switched to the patched version of OpenSSL within hours of it becoming available, plus have performed the following …
Good-bye bzip2 We started listing xz-compressed versions of kernel archives in all our announcements back in March 2013, and the time has come to complete the switch. Effective immediately, we will no longer be providing bzip2-compressed versions for new releases of the Linux kernel and other software. Any previously released …
Montreal frontend We have added another official frontend for serving the kernel content, courtesy of Vexxhost, Inc . There is now a total of three frontends, one in Palo Alto, California, one in Portland, Oregon, and one in Montreal, Quebec. This should allow for better geographic dispersion of official mirrors, as …
If you would like to mirror all or a subset of kernel.org git repositories, please use a tool we wrote for this purpose, called grokmirror. Grokmirror is git-aware and will create a complete mirror of kernel.org repositories and keep them automatically updated with no further involvement on your …
Special thanks to Benoît Monin for donating a MIT-licensed CSS theme to the kernel.org project to replace the one we hastily put together. Though the Pelican authors have since obtained a free-license commitment from the copyright owners of the CSS files shipping with Pelican, we wanted to have something …
We've implemented two oft-requested features today: The download links now default to .tar.xz versions of archives There is now a JSON file with the release information located in https://www.kernel.org/releases.json . If you've been screen-scraping the front page, please use this instead. If you have any …
Due to a failure in one of the rsync scripts during the maintenance window, the mirrors of /pub hierarchy on www.kernel.org got erased. We are resyncing them now from the master storage, but in the meantime you will probably get an occasional "Forbidden". The entirety of the archive …
You are probably wondering what happened to the site's look. Unfortunately, we've been alerted that the default theme shipped by Pelican (which we largely adapted) has an unclear license. Until this is cleared up, we've put together a quick-and-dirty cleanroom CSS reimplementation that preserves the functional aspects of the site …
