a xfrm policy. It also defines MLS policy for association { sendto,
recvfrom, polmatch }.
NOTE: When an inbound packet is not using an IPSec SA, a check is performed
between the socket label and the unlabeled sid (SYSTEM_HIGH MLS label). For
MLS purposes however, the target of the check should be the MLS label taken
from the node sid (or secmark in the new secmark world). This would present
a severe performance overhead (to make a new sid based on the unlabeled sid
with the MLS taken from the node sid or secmark and then using this sid as
the target). Pending reconciliation of the netlabel, ipsec and iptables contexts,
I have chosen to currently make an exception for unlabeled_t SAs if TE policy
allowed it. A similar problem exists for the outbound case and it has been similarly
handled in the policy below (by making an exception for unlabeled_t).
I am submitting the below limited patch pending a comprehensive patch from
Joy Latten at IBM (latten@austin.ibm.com).
I am not sure if I needed to manually do a "make tolib" in the flask subdir
and submit the results as well. Please let me know if I needed to.

The jffs2 filesystem is a filesystem for memory technology
devices (MTD), and xattr supporting on jffs2 is neccesary
to use SELinux with a small diskless PDA and so on.
This facility is queued for kernel 2.6.18 now, so I hope
to merge this small patch into the refpolicy repository.
