From 36447456e1cca853188505f2a964dbbeacfc7a7a Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Wed, 17 Jan 2018 20:27:11 +0200 Subject: ima/policy: fix parsing of fsuuid The switch to uuid_t invereted the logic of verfication that &entry->fsuuid is zero during parsing of "fsuuid=" rule. Instead of making sure the &entry->fsuuid field is not attempted to be overwritten, we bail out for perfectly correct rule.
