Detailed Description
We need to change the spec files of all applications that include a setuid application to remove the setuid flag and change to file capabilities.
Benefit to Fedora
This will benefit Fedora by making it more secure.
Scope
Open up a tracker bug, then open a bugzilla on every package that includes setuid applications. We would like to have the Fedora packaging committee codify this in rules and perhaps rpmlint to have smarts about identifying setuid apps and recommending file capabilities.
How To Test
Do a complete install of all Fedora packages and then search for any applications that have the setuid flag. If they do then the Feature is not complete. For any application that was setuid and now uses file capabilities, we need to test that the applications still works as it used to. Test rpmlint on an spec file containing a setuid app, and make sure it prints a proper warning.
User Experience
No change in User Experience should be expected.
Dependencies
We have a dependency that every package that contains a setuid app, is changed by the package owner. Although if we get some/most packages we feel that we have improved the security of the system.
Contingency Plan
None Necessary
Documentation
We should change documentation on packaging guidelines to talk about using file capabilities.
