                  Unlimited Arm Atomics Operations

UPDATES IN VERSION 2
====================

CVEs assigned.

ISSUE DESCRIPTION
=================

Software targeting pre-Armv8.1-A hardware, Xen included, commonly
implements atomics using Load/Store exclusive instructions in a loop
that will terminate once the store succeeded.

As per the Armv8-A Architecture Reference Manual (ARM DDI0487D.a),
paragraph 2.9.5 "Load-Exclusive and Store-Exclusive instruction usage
restrictions", page B2-143:

"""
It is permissible for the LoadExcl / StoreExcl loop not to make
forward progress if a different thread is repeatedly doing any of the
following in a tight loop:
- - Performing stores to a PA covered by the Exclusives monitor.
- - Prefetching with intent to write to a PA covered by the Exclusives
  monitor.
- - Executing data cache clean, data cache invalidate, or data cache clean
  and invalidate instructions to a
  PA covered by the Exclusives monitor.
- - Executing instruction cache invalidate all instructions.
- - Executing instruction cache invalidate by VA instructions to a PA
  covered by the Exclusives monitor.
"""

The underlying LoadExcl or StoreExcl operation might never succeed,
resulting in an unlimited loop in the hypervisor.

A similar, but independent, issue occurs when compare-and-exchange
operations are misused:

 do
 {
   old = *addr;
 }
 while (cmpxchg(addr, old, new) != new);

This pattern is not safe, because the operation may continuously fail if
another thread in a guest is continuously modifying the value. An
instance of this pattern was found in Xen.


IMPACT
======

An attacker in a domU could perform a denial of service attack on Xen by
accessing a memory region shared with the hypervisor, while Xen is
performing an atomic operation on the same region. As a result Xen could
end up looping boundlessly. See the issue description for more details
on the memory accesses that affect LoadExcl and StoreExcl operations.


VULNERABLE SYSTEMS
==================

Systems running all versions of Xen are affected.

x86 processors are not affected.
Arm processors are vulnerable, both Armv7 and Armv8.


NOTE REGARDING LACK OF EMBARGO
==============================

Other Open Source projects released fixes to the public before we could
arrange for an organized disclosure.


MITIGATION
==========

There are no mitigations.


CREDITS
=======

This issue was discovered by Andrew Cooper of Citrix and Julien Grall of
Arm.


RESOLUTION
==========

Applying the appropriate attached patches resolve this issue.

Please note that these patches enable SILO mode by default, which denies
communications between unprivileged guests. Page sharing between domUs,
thus inter-domains communications and driver domains, are not allowed by
SILO mode. It is necessary to have a complete fix to this vulnerability.

SILO mode is required because the fix relies on Xen being able to
pinpoint the domain owner of the shared page. Without SILO mode, a guest
could share a page with Xen and with a second guest (e.g via grant
table): the second guest could use the foreign page to attack the
hypervisor.

Users are encouraged to write their own Flask policies to enable more
complex configurations. For example, Flask could be used to allow page
sharing between trusted virtual machines (trusted by the administrator).
