[rsbac] MAC: request MODIFY_SYSTEM_DATA, target NETDEV

[Gergely Lónyai]

Hi,

Yes. I add kernel-rsbac to my desktop, and i sucking the MAC/RC :-(
[secoff at noder ~]$ attr_set_fd MAC DEV MODIFY_SYSTEM_DATA 1 /usr/lib/multiload-applet-2
attr_set_fd: Invalid attribute MODIFY_SYSTEM_DATA
[secoff at noder ~]$ attr_set_fd MAC DEV GET_STATUS_DATA 1 /usr/lib/multiload-applet-2
attr_set_fd: Invalid attribute GET_STATUS_DATA

But find a simphatic program: attr_set_net but not inclde "MAC NETDEV" pair
2. simpatic program: acl_grant but not include MAC
acl_grant USER 1000 MODIFY_SYSTEM_DATA NETDEV :DEFAULT:
