Red Hat has contributed extensively to Free and Open Source software. A partial list of software that Red Hat has contributed towards include the following.

Red Hat has a similar page with many more details on its involvement, and a list of projects that Red Hat is heavily involved with.

Fedora Project

Red Hat is the primary sponsor of Fedora Project and provides hosting, engineering and other resources. It has several hundred active developers participating and leading the project in different ways in coordination with the volunteer community members. It is a highly successful model pionoreed by Red Hat within the Fedora Project that has inspired several other distributions like OpenSUSE and free software projects like MySQL and !OpenSolaris.

Red Hat Enterprise Linux

Red Hat Enterprise is a open source product based on Fedora that is commercially supported by Red Hat.

Upstream Focus

Fedora Project has a strong focus on not deviating from upstream as much as possible in all the different software it includes in the repository. The following is a general set of best practice guidelines on why this is a good idea, tips for sending your patches upstream, and the potential exceptions Fedora might make. The primary goal is to share the benefits of a common codebase for end users and developers while simultaneously reducing unnecessary maintenance efforts.

Linux Kernel

Red Hat is the largest contributor and Red Hat developers are the leading contributors.

Xorg

Red Hat is also the largest contributor to Xorg according to this report.
