xserver_use(xdm, staff, staff_nsplugin_t)
All interaction between application and X Server
template - xserver_common_user_template(staff, staff_r, staff_t)
This generates all of the user types/rules for a user X Sessionps
started by the user, Calls out to xserver_common_template
interface - xserver_common_app(staff, staff_nsplugin_t)
This defines all the common rules for a confined application like
nsplugin running in the user domain
Then we can begin to write communications between staff and unconfined_t
or other user domains.
After some discussion, it's been decided that the desktop effort here
should continue devoting time to X policy development. My earlier
statements notwithstanding.
Thanks, I think you are doing the right thing.
What's your current policy patch for the above?
The problem I have is the compiler is too stupid to understand the
differences between a gen_requires block defining the required types and
the actual type definition.
So I end up in a catch 22 where the compiler tells me I need to require
$1_rootwindow_t, but if I gen_require type $1_rootwindow_t, it tells me
I have a duplicate definition.
I encountered a bug where the "get_type_attr_decl.sed" script that
reorders declarations wasn't matching properly, because it depends on
a _comment_ at the end of the block to work (I forgot to use
gen_require).
This sounds like a different bug but it might be related.
So if you have a derived type in a gen_requires block the compiler can
not handle it.
