From fb7b71b86f5591cc4bf83fcf4081634f4c2980aa Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Mon, 14 Nov 2022 23:56:52 +0100 Subject: contrib/apparmor: Merge pasta and passt profiles, update rules AppArmor resolves executable links before profile attachment rules are evaluated, so, as long as pasta is installed as a link to passt, there's no way to differentiate the two cases. Merge the two profiles and leave a TODO note behind, explaining two possible ways forward. Update the rules so that passt and pasta are actually usable, once the profile is installed. Most required changes are related to isolation and sandboxing features.
