On a Debian 10 system, I saw denials for ulogd service:
* It uses a pipe with itself:
type=AVC msg=audit(1567874422.328:13744): avc: denied { write }
for pid=11416 comm="ulogd" path="pipe:[29006]" dev="pipefs"
ino=29006 scontext=system_u:system_r:ulogd_t
tcontext=system_u:system_r:ulogd_t tclass=fifo_file permissive=0
* It enumerates users in /run/systemd/dynamic-uid/ when changing to the
ulog user (which is not dynamic):
type=AVC msg=audit(1567874512.576:13748): avc: denied { read } for
pid=18290 comm="ulogd" name="dynamic-uid" dev="tmpfs" ino=16527
scontext=system_u:system_r:ulogd_t
tcontext=system_u:object_r:init_var_run_t tclass=dir permissive=0
* It connects to the system D-Bus socket in order to call GetDynamicUser:
type=AVC msg=audit(1567875114.147:13761): avc: denied { write }
for pid=28135 comm="ulogd" name="system_bus_socket" dev="tmpfs"
