Every device has a CPU. This is not device specific. Allow every domain to read these files/directories. For unknown reasons, these files are accessed by A LOT of processes. Allow ueventd to write to these files. This addresses the following denials seen on mako: <5>[ 4.935602] type=1400 audit(1383167737.512:4): avc: denied { read } for pid=140 comm="ueventd" name="cpu0" dev="sysfs" ino=3163 scontext=u:r:ueventd:s0 tcontext=u:object_r:sysfs_devices_system_cpu:s0 tclass=dir <5>[ 4.935785] type=1400 audit(1383167737.512:5): avc: denied { open } for pid=140 comm="ueventd" name="cpu0" dev="sysfs" ino=3163 scontext=u:r:ueventd:s0 tcontext=u:object_r:sysfs_devices_system_cpu:s0 tclass=dir <5>[ 4.935937] type=1400 audit(1383167737.512:6): avc: denied { search } for pid=140 comm="ueventd" name="cpu0" dev="sysfs" ino=3163 scontext=u:r:ueventd:s0 tcontext=u:object_r:sysfs_devices_system_cpu:s0 tclass=dir <5>[ 4.936120] type=1400 audit(1383167737.512:7): avc: denied { write } for pid=140 comm="ueventd" name="uevent" dev="sysfs" ino=3164 scontext=u:r:ueventd:s0 tcontext=u:object_r:sysfs_devices_system_cpu:s0 tclass=file <5>[ 4.936303] type=1400 audit(1383167737.512:8): avc: denied { open } for pid=140 comm="ueventd" name="uevent" dev="sysfs" ino=3164 scontext=u:r:ueventd:s0 tcontext=u:object_r:sysfs_devices_system_cpu:s0 tclass=file Change-Id: I4766dc571762d8fae06aa8c26828c070b80f5936
