No SELinux security context (/etc/crontab)



I have enabled SELinux in my yocto project(warrior branch) but cron is not functioning because of some SELinux context isuue. I am using minimum SELinux policy. Here is the error from `/var/log/messages`


    Oct  9 04:50:01 panther2 crond[261]: ((null)) No SELinux security context (/etc/crontab)       

    Oct  9 04:50:01 panther2 crond[261]: (root) FAILED (loading cron table)                      


Here are some contexts for relevant files,


    root@panther2:~# ps -efZ | grep cron

    system_u:system_r:kernel_t:s0   root       464     1  0 04:54 ?    00:00:00 /usr/sbin/crond -n


    root@panther2:~# ls -lZ /etc/crontab

    -rw-------. 1 root root system_u:object_r:unconfined_t:s0 653 Oct  9  2019 /etc/crontab


    root@panther2:~# ls -lZ /usr/sbin/crond

    -rwxr-xr-x. 1 root root system_u:object_r:unlabeled_t:s0 68160 Oct  9  2019 /usr/sbin/crond


Any help? Thanks !!
