How about changing the policy to (c over d) && ((d over t) || (c over t))?
Given that (c over d) is a must, which is always checked somewhere higher
in the call stack as Daniel pointed out, permitting (d over t) or (c
over t) actually infers
permitting the other.
- if you permit (d over t) but not (c over t):
Given (c over t),
(c) can first map the src page from (t) into its own memory space and then map
this page from its own memory space to (d)'s memory space.
- if you permit (c over t) but not (d over t):
Given (d over t),
(c) can first map (d)'s pages into its own memory space and modify (d)'s code
to issues a hypercall that maps (t)'s memory pages into (d)'s memory space.
I'm not very familiar with Xen's security model. So I might be totally
wrong here.
If so, please correct me.
And if you still think adding a new subop is necessary, do you have
any suggestions
on this?
Cheers,
Zhongze Liu

blackskygg: I think you want to pass the current domain in
parameter, i.e having 3 domains argument.
because your solution only works when XSM is not enabled (this is
the dummy callback)
when XSM is enabled, the policy would be specificed by the administrator
he needs to be able to know which domain was doing the configuration.

I should have made @space uint16_t, too. I'll fix this. Or do you have
any good reasons to
make both of them unsigned int?

add a wrapper to do that.

Hi Ian,
Thanks for pointing out the problems. I've consulted several
maintainers about this
and have drafted a new patch for it (in a new [patch v2] thread).
Please have a look
at it. Thanks.
Cheers,

Hi Xen developers,
Several -Wimplicit-fallthrough were found under
tools/firmware/etherboot/ipxe with GCCv7.1.1.
I'm not sure whether this is the right place to report this since it's
not part of the xen source tree,
But I think I'd better let you know.

Hi Wei Liu,
Thanks for your review and approval.
Then I'll revise my proposal according to these conclusions.
