These allow +giving various kinds of specific privileges to individual users, without giving +them full root permissions. + +Although the Hurd design should faciliate implementing such features in a quite +natural fashion, there is no support for POSIX capabilities yet. As a +consequence, libcap is not available on the Hurd, and thus various packages +using it can not be easily built in Debian GNU/Hurd. + +The first goal of this project is implementing a dummy libcap, which doesn't +actually do anything useful yet, but returns appropriate status messages, so +program using the library can be built and run on Debian GNU/Hurd. + +Having this, actual support for at least some of the capabilities should be +implemented, as time permits. This will require some digging into Hurd +internals. + +Some knowledge of POSIX capabilities will need to be obtained, and for the +latter part also some knowledge about the Hurd architecture. This project is +probably doable without previous experience with either, though. + +Possible mentors: + +Exercise: Make libcap compile on Debian GNU/Hurd. It doesn't need to actually +do anything yet -- just make it build at all for now. -- cgit v1.2.3
