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()") Signed-off-by: Petr Vorel <pvorel@suse.cz> --- Hi, assuming behavior prior c52657d93b05 was correct.
