Becoming a maintainer

If someone (covered by a copyright assignment) is doing good work, established developers may approve them for commit access (through mail to for people with existing sourceware accounts, or the online account application process for people without existing accounts).

Maintainers for libc and ports add-on

Write after Consensus and/or approval from machine maintainer (alphabetical order by last name):

Operating system port maintainers

Machine maintainers

Distribution Maintainers

At the distribution level there are developers who are responsible for glibc in their particular distribution. These developers are an excellent point of contact when we have distribution related issues or questions and they should be consulted on issues that have far reaching effects on the distributions.

In alphabetical order by distribution:

Maintainers for the website

Blanket commit with the understanding that consultation and discretion are required. We maintain two websites, the official FSF website and another site at that forwards to the FSF one. See the Website Maintenance.

Maintainers for Bugzilla

Changes to bugzilla should be discussed by the entire community.

Maintainers for linuxthreads add-on

Reviewers by component

This is not a table of designated component-wise maintainers (yet). The intent of this table is to record which project members are either interested in or consider themselves capable of reviewing changes in the respective components. The component list is taken from bugzilla. Over time, an additional column could be added to record component owners.

Accounts on

The glibc source is graciously hosted by Red Hat on You will need an account on before you can become a developer. Use this handy dandy form to make that request:

Source Control ACLs

Developers with blanket commit are responsible for authorizing access (through ) to the glibc group for the glibc and glibc-ports repositories. Once you are in the glibc group you will have write access to the repositories.

Contacting maintainers

The normal way to contact maintainers about bugs is via the Bugzilla Procedures. Important security-related bugs, where public notification may cause harm to users, can be reported privately to the maintainers via the abovementioned email addresses. People are also welcome to report bugs via more-formal approaches, e.g., the U.S. Computer Emergency Readiness Team (US-CERT). There is a formal channel between US-CERT and the GNU C library developers.

Common sense is advised for deciding how important a security-relevant bug is. Triage tools are available.

LinkedIn Group

We have a LinkedIn Group for GLIBC Developers. The group is moderated by Carlos O'Donell.

Ohloh Group

We have an Ohloh Project for tracking glibc. The project is moderated by Carlos O'Donell.
