Subject: [PATCH] memfd: fix configure test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Recent glibc added memfd_create in sys/mman.h. This conflicts with
the definition in util/memfd.c:
/builddir/build/BUILD/qemu-2.11.0-rc1/util/memfd.c:40:12: error: static declaration of memfd_create follows non-static declaration
Fix the configure test, and remove the sys/memfd.h inclusion since the
file actually does not exist---it is a typo in the memfd_create(2) man
page.

Subject: [PATCH] target/i386: add memory encryption feature cpuid support
AMD EPYC processors support memory encryption feature. The feature
is reported through CPUID 8000_001F[EAX].
Fn8000_001F [EAX]:
Bit 0 Secure Memory Encryption (SME) supported
Bit 1 Secure Encrypted Virtualization (SEV) supported
Bit 2 Page flush MSR supported
Bit 3 Ecrypted State (SEV-ES) support
when memory encryption feature is reported, CPUID 8000_001F[EBX] should
provide additional information regarding the feature (such as which page
table bit is used to mark pages as encrypted etc). The information in EBX
and ECX may vary from one family to another hence we use the host cpuid
to populate the EBX information.
The details for memory encryption CPUID is available in AMD APM
(https://support.amd.com/TechDocs/24594.pdf) Section E.4.17

+Create a Secure Encrypted Virtualization (SEV) guest object, which can be used

+
+The @option{sev-device} provides the device file to use for communicating with
+the SEV firmware running inside AMD Secure Processor. The default device is
+'/dev/sev'. If hardware supports memory encryption then /dev/sev devices are
+created by CCP driver.
+
+The @option{cbitpos} provide the C-bit location in guest page table entry to use.
+
+The @option{policy} provides the guest policy to be enforced by the SEV firmware
+and restrict what configuration and operational commands can be performed on this
+guest by the hypervisor. The policy should be provided by the guest owner and is
+bound to the guest and cannot be changed throughout the lifetime of the guest.
+The default is 0.
+
+If guest @option{policy} allows sharing the key with another SEV guest then
+@option{handle} can be use to provide handle of the guest from which to share
+the key.
+
+The @option{dh-cert-file} and @option{session-file} provides the guest owner's

+Create a Secure Encrypted Virtualization (SEV) guest object, which can be used

+created by CCP driver.
+
+The @option{cbitpos} provide the C-bit location in guest page table entry to use.
+
+The @option{policy} provides the guest policy to be enforced by the SEV firmware
+and restrict what configuration and operational commands can be performed on this
+guest by the hypervisor. The policy should be provided by the guest owner and is
+bound to the guest and cannot be changed throughout the lifetime of the guest.
+The default is 0.
+
+If guest @option{policy} allows sharing the key with another SEV guest then

The KVM_SEV_LAUNCH_START command creates a new VM encryption key (VEK).
The encryption key created with the command will be used for encrypting
the bootstrap images (such as guest bios).

the guest policy allows the debugging.

Also bypass the test for query-sev-launch-measure qmp command test,
since it causes the qemu-testsuite package to fail to build.

Subject: [PATCH] migration: warn about inconsistent spec_ctrl state
As an attempt to help the user do the right thing, warn if we
detect spec_ctrl data in the migration stream, but where the
cpu defined doesn't have the feature. This would indicate the
migration is from the quick and dirty qemu produced in January
2018 to handle Spectre v2. That qemu version exposed the IBRS
cpu feature to all vcpu types, which helped in the short term
but wasn't a well designed approach.
Warn the user that the now migrated guest needs to be restarted
as soon as possible, using the spec_ctrl cpu feature flag or a
*-IBRS vcpu model specified as appropriate.

Subject: [PATCH] i386: Compensate for KVM SPEC_CTRL feature availability bug
As we move away from the quick and dirty qemu solution for
Spectre v2, it was found that KVM wasn't reporting the SPEC_CTRL
feature when it in fact was present due to microcode update.
This patch compensates for that bug by checking for the feature
in QEMU code (like the quick and dirty solution did), instead of
simply relying on KVM for that information.

- Update to v2.11.1, a stable, (mostly) bug-fix-only release
In addition to bug fixes, of necessity fixes are needed to
address the Spectre v2 vulnerability by passing along to the
guest new hardware features introduced by host microcode updates.
A January 2018 release of qemu initially addressed this issue
by exposing the feature for all x86 vcpu types, which was the
quick and dirty approach, but not the proper solution. We remove
that initial patch and now rely on the upstream solution. This
update instead defines spec_ctrl and ibpb cpu feature flags as
well as new cpu models which are clones of existing models with
either -IBRS or -IBPB added to the end of the model name. These
new vcpu models explicitly include the new feature(s), whereas
the feature flags can be added to the cpu parameter as with other
features. In short, for continued Spectre v2 protection, ensure
that either the appropriate cpu feature flag is added to the QEMU
command-line, or one of the new cpu models is used. Although
migration from older versions is supported, the new cpu features
won't be properly exposed to the guest until it is restarted with
the cpu features explicitly added. A reboot is insufficient.
A warning patch is added which attempts to detect a migration
from a qemu version which had the quick and dirty fix (it only
detects certain cases, but hopefully is helpful.)
s390x guest vulnerability to Spectre v2 is also addressed in this
update by including support for bpb and ppa/stfle.81 features.
(CVE-2017-5715 bsc#1068032)
For additional information on Spectre v2 as it relates to QEMU,
see: https://www.qemu.org/2018/02/14/qemu-2-11-1-and-spectre-update/
- Unfortunately, it was found that our current KVM isn't correctly
indicating support for the spec-ctrl feature, so I've added a patch
to still detect that support within QEMU. This is of course a
temporary kludge until KVM gets fixed. (bsc#1082276)
- The SEV support patches are updated to the v9 series.
- Fix incompatibility with recent glibc (boo#1081154)
- Add Supplements tags for the guest agent package in an attempt to
auto-install for QEMU and Xen SUSE Linux guests (fate#323570)

detects certain cases, but hopefully is helpful.)
s390x guest vulnerability to Spectre v2 is also addressed in this
update by including support for bpb and ppa/stfle.81 features.
(CVE-2017-5715 bsc#1068032)
For additional information on Spectre v2 as it relates to QEMU,
see: https://www.qemu.org/2018/02/14/qemu-2-11-1-and-spectre-update/
- Unfortunately, it was found that our current KVM isn't correctly
indicating support for the spec-ctrl feature, so I've added a patch
to still detect that support within QEMU. This is of course a
temporary kludge until KVM gets fixed. (bsc#1082276)
- The SEV support patches are updated to the v9 series.
- Fix incompatibility with recent glibc (boo#1081154)
- Add Supplements tags for the guest agent package in an attempt to
auto-install for QEMU and Xen SUSE Linux guests (fate#323570)
