apt: allow preventing shutdown by calling a systemd-logind D-Bus method Since apt 1.8.1 (more precisely since commit https://salsa.debian.org/apt-team/apt/commit/60cc44d160af02c49614653c97bfa3e4e5c9601d), apt calls D-Bus method "Inhibit" of interface "org.freedesktop.login1.Manager" in order to prevent a shutdown from happening while installing software. The call from apt to systemd-logind was already allowed through unconfined_dbus_send(apt_t), but not the reply, which triggered the following audit log: type=USER_AVC msg=audit(1567780304.196:651): pid=287 uid=105 auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t msg='avc: denied { send_msg } for msgtype=method_return dest=:1.137 spid=290 tpid=29557 scontext=system_u:system_r:systemd_logind_t tcontext=sysadm_u:sysadm_r:apt_t tclass=dbus permissive=0 exe="/usr/bin/dbus-daemon" sauid=105 hostname=? addr=? terminal=?'
