[yocto] [meta-selinux] Regarding "systemd" support with refpolicy-minimum v20151208

[Shrikant Bobade]

Hi,

Using refpolicy-minimum v20151208 with systemd as init manager,

I am facing few issues during enforcing mode,
1. systemd service status check, start & stop
2. auditd logfile error, so it is mixing with the boot log.
3. also other avc denials related to tmpfs & other types etc..


setup details:poky and meta-selinux: both at master head & systemd enabled.
with these SELinux booleans enabled: i.systemd_tmpfiles_manage_all
ii.allow_mount_anyfile

captured the avc denial to fix the systemd execution well, attached
SELinux-Modules.txt :- the allow rules generated using audit tools.
I am trying to merge these module into actual refpolicy modules, so we get
the out of box experience for smooth systemd execution.
Observed policy store seems corrupted some time, when start inserting the
prepared policy modules allow rules into actual refpolicy modules..

Does anyone also faced similar issues?

Any pointers or references will be a great help.


Thanks
Shrikant
