Commit Message

Petr Vorel July 24, 2020, 7 a.m. UTC 
Check with cat, because file attributes were fixed in
ffb122de9a60 ("ima: Reflect correct permissions for policy")
in v4.18.

Added into ima_setup.sh as it'll be used next commit in another test.

Fixes: d2768c84e ("IMA: Add a test to verify measurement of keys")
