Subject: ima/policy: fix parsing of fsuuid
From: Mike Rapoport <rppt@xxxxxxxxxxxxxxxxxx>
commit 36447456e1cca853188505f2a964dbbeacfc7a7a upstream.
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.
Fixes: 787d8c530af7 ("ima/policy: switch to use uuid_t")
