BTW, aside from the wrong type on the file, the denial is clearly a MLS
denial - look at the levels on the two contexts. You have a process
whose current/low level is s0 (aka SystemLow) trying to getattr (read
flow) a file at s15:c0.c1023 (aka SystemHigh). No surprises there.
The high level of the process is only used as a ceiling for newrole -l
or if the process' domain has certain MLS privileges allowing it to act
up to its ceiling.
