Ideally access to this information would be restricted so that any unknown access would be logged, but lxc/d currently aren't ready for this so in order to _not_ force lxc/d to probe whether enforcement is enabled, open up read access to the sysctls for unprivileged user namespace mediation. https://github.com/canonical/lxd/issues/11920#issuecomment-1756110109 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2040194/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
