Subject: [PATCH v2] ima: fix wrong signed policy requirement when not appraising
Date: Wed, 15 May 2019 08:18:07 +0200 [thread overview]
Message-ID: <20190515061807.6257-1-pvorel@suse.cz> (raw)
Kernel booted just with ima_policy=tcb (not with
ima_policy=appraise_tcb) shouldn't require signed policy.
Regression found with LTP test ima_policy.sh.
Fixes: c52657d93b05 ("ima: refactor ima_init_policy()")
Suggested-by: Mimi Zohar <zohar@linux.ibm.com>
Signed-off-by: Petr Vorel <pvorel@suse.cz>
---
Changelog v1->v2:
* Use POLICY_CHECK instead of ima_use_appraise_tcb.
Thanks Mimi for obvious hint :).
Kind regards,
Petr
