[Xen-devel] [PATCH] xen/xsm/flask: Fix permission tables

[Stephen Smalley <sds@xxxxxxxxxxxxx>]

At some point, it seems that someone manually added Flask permission
definitions to one header file without updating the corresponding policy
configuration or the other related table.  The end result is that we can
get uninterpretable AVC messages like this:
# xl dmesg | grep avc
(XEN) avc:  denied  { 0x4000000 } for domid=0
scontext=system_u:system_r:dom0_t tcontext=system_u:system_r:domU_t
tclass=domain

Fix this by updating the flask config and regenerating the headers from
it.  In the future, this can be further improved by integrating the
automatic generation of the headers into the build process as is
presently done in SELinux.
