Glad to see someone else looking at the ARM kernel.

Maybe some usb devices. Which ones...I don't know. :)

Note that the audit system on ARM is dysfunctional. No one has ever taken the
time to write the requisite code in arch/arm/kernel/ptrace.c to call
audit_syscall_entry(). Without that code upstream (or as a patch), the audit
system is limited to user space originating events. I don't know if SE Linux
AVC's are affected by the audit system not having its hands on a lot of
information during the syscall.

Netfilter is needed badly on that arch since the default system image has a
mail server listening to the public IP address and running as root. Iptables
is needed to block this access.
