 When all three domains are different, how does the changed
 policy reflect the original "d has privilege over t" requirement?
 I understand you want to relax the current condition, but this
 shouldn't come at the price of granting access when access
 should be denied. Nor the inverse - the current domain not
 having privilege over both does also not mean d doesn't have
 the necessary privilege over t.

 I continue to think that you can't validly retrofit the new
 intended functionality onto the existing hypercall, even if
 nothing except the permission check needs to be different.

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

[Xen-devel] [PATCH 2/6] x86: configure vmcs for Intel processor trace virtualization

2017-10-22 Thread Luwei Kang 
This patch configure VMCS to make Intel PT output address can be
treat as guest physical address and translated by EPT when
intel_pt option is true.
There have some constraint condition on VMCS configuration,
otherwise will cause VM entry failed.

1. If the “Guest PT uses Guest Physical Addresses” execution
   control is 1, the “Clear IA32_RTIT_CTL on exit” exit
   control and the “Load IA32_RTIT_CTL on entry” entry
   control must also be 1.

2. If the “Guest PT uses Guest Physical Addresses” execution
   control is 1, the "enable EPT" execution control must
   also be 1.

[Xen-devel] [PATCH 0/6] Intel Processor Trace virtulization enabling

2017-10-22 Thread Luwei Kang 
Hi All,

Here is a patch-series which adding Processor Trace enabling in XEN guest. You 
can get It's software developer manuals from:
https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf
In Chapter 5 INTEL PROCESSOR TRACE: VMX IMPROVEMENTS.

Introduction:
Intel Processor Trace (Intel PT) is an extension of Intel Architecture that 
captures information about software execution using dedicated hardware 
facilities that cause only minimal performance perturbation to the software 
being traced. Details on the Intel PT infrastructure and trace capabilities can 
be found in the Intel 64 and IA-32 Architectures Software Developer’s Manual, 
Volume 3C.

The suite of architecture changes serve to simplify the process of virtualizing 
Intel PT for use by a guest software. There are two primary elements to this 
new architecture support for VMX support improvements made for Intel PT.
1. Addition of a new guest IA32_RTIT_CTL value field to the VMCS.
  — This serves to speed and simplify the process of disabling trace on VM 
exit, and restoring it on VM entry.
2. Enabling use of EPT to redirect PT output.
  — This enables the VMM to elect to virtualize the PT output buffer using EPT. 
In this mode, the CPU will treat PT output addresses as Guest Physical 
Addresses (GPAs) and translate them using EPT. This means that Intel PT output 
reads (of the ToPA table) and writes (of trace output) can cause EPT 
violations, and other output events.


Luwei Kang (6):
  x86: add a flag to enable Intel processor trace
  x86: configure vmcs for Intel processor trace virtualization
  x86: add intel proecessor trace support for cpuid
  x86: add intel processor trace context
  x86: implement intel processor trace context switch
  x86: Pass through intel processor trace MSRs
