Description Jason Tibbitts 2016-02-24 22:23:26 UTC
When running amrecover (part of the amanda package) as root to restore some files, I find that the amanda cannot manipulate the tape changer to load the necessary tapes.  I switched to permissive and retried; here are the logged AVCs:

type=AVC msg=audit(1456352333.877:1085): avc:  denied  { read write } for  pid=11898 comm="mtx" name="sg8" dev="devtmpfs" ino=12562 scontext=system_u:system_r:amanda_t:s0 tcontext=system_u:object_r:scsi_generic_device_t:s0 tclass=chr_file permissive=1

In enforcing mode, I just see the first AVC.
