I really liked a feature that LineageOS used to have but removed, where you could lie to apps about what privileges they have.

Oh, you want access to my contacts? Here you go! Yes, sorry, I don’t actually have any contacts. You can put some in there, but no one else will see them.

Oh, you absolutely need my precise location information? Okay, here is a point I selected on the map. Yes, I never move from that spot. Maybe the GPS signal isn’t good?

Oh, you want to send notifications? Of course! Oh, you thought that implied that they would be displayed somewhere?

Applications should not be told about users’ notification preferences. The app should control what kinds of things it sends notifications for. The notification subsystem should choose which are shown and when.

Can anyone recommend a good, simple markdown blog? Using GitHub for this is one option but I would also like to keep the current domain name (blog.namei.org).

@AdrianVovk and btw, a related problem needs to be solved for confidential computing payloads, where IPE is not the source of trust but is needed to authorize execution of code which is runtime-installed in a confidential domain. i.e. enforce delegated trust.

@AdrianVovk you could do this with IPE if desired, it is intended to be extensible (I would use an SELinux label associated with the sandbox), but it does need static kernel code modification vs BPF JIT.
