Linux Kernel (kernel.org)

kernel.org is the distribution site for the Linux kernel and other open source software, operated by the Linux Kernel Organization, a California Public Benefit Corporation established in 2002 and recognized by the IRS as a 501(c)3 private operating foundation. The organization distributes the Linux kernel and other open source software to the public without charge. The Linux Foundation manages the organization and provides technical, financial and staffing support for the kernel.org infrastructure.

The site publishes kernel releases across mainline, stable, longterm and linux-next tracks, with tarballs, patches, incremental patches, diffs, changelogs and PGP signatures available for download. Releases are accessible over HTTP, Git and rsync. Additional resources include Git trees, documentation, kernel mailing lists, Patchwork, wikis, Bugzilla and mirrors. The Linux kernel is described as a clone of the Unix operating system, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net, aiming toward POSIX and Single UNIX Specification compliance. The site is intended for developers, maintainers and users who need kernel source, release information and related project resources.
