From 6d3e426d2f8af68ea471ebfe4b3dc89e5c8ed62f Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Wed, 6 Sep 2023 20:39:12 +0200 Subject: apparmor: Use abstractions/nameservice to deal with symlinked resolv.conf While abstractions/nameservice appeared too broad and overkill for our simple need (read-only resolv.conf access), it properly deals with symlinked resolv.conf files generated by systemd-resolved, NetworkManager or suchlike. If we just grant read-only access to /etc/resolv.conf, we'll fail to read nameserver information in rather common configurations, because AppArmor won't follow the symlink.
