Feature changed by: Dainius Masiliunas (GreatEmerald) Feature #314778, revision 3 Title: Use polkit for YaST privilege management openSUSE Distribution: Unconfirmed Priority Requester: Desirable Requested by: Dainius Masiliunas (greatemerald) Partner organization: openSUSE.org Description: At the moment of writing, YaST relies on having root privileges through a graphical sudo in order to view and carry out most tasks. However, there is no reason why simply displaying those tasks should be restricted like that. YaST should always be started with user privileges, and only ask for additional privileges when they are truly needed - when the selected tasks should be carried out. This can be achieved by using polkit. It also brings a lot of other benefits. Relations: - Discussion of the idea on the mailing list (url: http://lists.opensuse.org/yast-devel/2007-10/msg00024.html) Use Case: Users who do not have access to the root password currently also do not have access to a lot of functionality that does not actually require the password, such as searching for package information. Users that do administrative tasks are also subjecting the system to possible security risks by running YaST with full root privileges. Using polkit would increase security and prevent potential user mistakes. Business case (Partner benefit): openSUSE.org: Using polkit, the graphical interface of YaST would always be run as a normal user. That means that code that should not - have elevated privileges - like GUI - would not run with them.

It seems to me that it would just need a few privilege-awareness changes. Instead of presuming that each module runs as root, you instead queue up the changes that the module wants to do to the system, then pressing the Finish button asks for the password and applies the changes. The workflow stays pretty much the same, because that's already what most YaST modules do as it is. The only thing that is missing is a way to integrate the queue with polkit, and review the actions that each module wishes to take (so that it wouldn't always require a password when one is not needed, and would ask only for the necessary amount of privileges they need). Even without the extensive review, it would already be an improvement over what we have now, since at least the GUI would always run as the user, and not root, for added security and theme consistency with the desktop. -- openSUSE Feature: https://features.opensuse.org/314778
