From 08344dacb14bdda5f6ee1fa36dab36776101115b Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Fri, 16 Feb 2024 09:43:12 +0100 Subject: [PATCH] selinux: Allow pasta to remount procfs Partially equivalent to commit abf5ef6c22d2 ("apparmor: Allow pasta to remount /proc, access entries under its own copy"): we should allow pasta to remount /proc. It still works otherwise, but further UID remapping in nested user namespaces (e.g. pasta in pasta) won't.
