Xiao Feng Ren 274250c301 s390x/css: add s390-squash-mcss machine option
We want to support real (i.e. not virtual) channel devices
even for guests that do not support MCSS-E (where guests may
see devices from any channel subsystem image at once). As all
virtio-ccw devices are in css 0xfe (and show up in the default
css 0 for guests not activating MCSS-E), we need an option to
squash both the virtio subchannels and e.g. passed-through
subchannels from their real css (0-3, or 0 for hosts not
activating MCSS-E) into the default css. This will be
exploited in a later patch.

Stefan Hajnoczi adb354dd1e pci, virtio, vhost: fixes
A bunch of fixes that missed the release.
 Most notably we are reverting shpc back to enabled by default state
 as guests uses that as an indicator that hotplug is supported
 (even though it's unused). Unfortunately we can't fix this
 on the stable branch since that would break migration.

Greg Kurz 66453cff9e virtio: allow broken device to notify guest
According to section 2.1.2 of the virtio-1 specification:

"The device SHOULD set DEVICE_NEEDS_RESET when it enters an error state that
a reset is needed. If DRIVER_OK is set, after it sets DEVICE_NEEDS_RESET,
the device MUST send a device configuration change notification to the
driver."

Commit "f5ed36635d8f virtio: stop virtqueue processing if device is broken"
introduced a virtio_error() call that just does that:

- internally mark the device as broken
- set the DEVICE_NEEDS_RESET bit in the status
- send a configuration change notification

Unfortunately, virtio_notify_vector(), called by virtio_notify_config(),
returns right away when the device is marked as broken and the notification
isn't sent in this case.

The spec doesn't say whether a broken device can send notifications
in other situations or not. But since the driver isn't supposed to do
anything but to reset the device, it makes sense to keep the check in
virtio_notify_config().

Marking the device as broken AFTER the configuration change notification was
sent is enough to fix the issue.

Marcel Apfelbaum 2fa356629e Revert "hw/pci: disable pci-bridge's shpc by default"
This reverts commit dc0ae76770.

Disabling the shpc controller has an undesired side effect.
The PCI bridge remains with no attached devices at boot time,
and the guest operating systems do not allocate any resources
for it, leaving the bridge unusable. Note that the behaviour
is dictated by the pci bridge specification.

Revert the commit and leave the shpc controller even if is not
actually used by any architecture. Slot 0 remains unusable at boot time.

Keep shpc off for QEMU 2.9 machines.

TYPE_S390_PCI_HOST_BRIDGE is a subclass of TYPE_PCI_HOST_BRIDGE,
which is a subclass of TYPE_SYS_BUS_DEVICE. TYPE_SYS_BUS_DEVICE
already sets user_creatable=false, so we don't require an
explicit user_creatable=false assignment in
s390_pcihost_class_init().

sysbus-fdc and SUNW,fdtwo devices need IRQs to be wired and mmio
to be mapped, and can't be used with -device. Unset
user_creatable on their device classes.

Eduardo Habkost e4f4fb1eca sysbus: Set user_creatable=false by default on TYPE_SYS_BUS_DEVICE
commit 33cd52b5d7 unset
cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all
sysbus devices appear on "-device help" and lack the "no-user"
flag in "info qdm".

To fix this, we can set user_creatable=false by default on
TYPE_SYS_BUS_DEVICE, but this requires setting
user_creatable=true explicitly on the sysbus devices that
actually work with -device.

Fortunately today we have just a few has_dynamic_sysbus=1
machines: virt, pc-q35-*, ppce500, and spapr.

virt, ppce500, and spapr have extra checks to ensure just a few
device types can be instantiated:

* virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE.
* ppce500 supports only TYPE_ETSEC_COMMON.
* spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE.

This patch sets user_creatable=true explicitly on those 4 device
classes.

Now, the more complex cases:

pc-q35-*: q35 has no sysbus device whitelist yet (which is a
separate bug). We are in the process of fixing it and building a
sysbus whitelist on q35, but in the meantime we can fix the
"-device help" and "info qdm" bugs mentioned above. Also, despite
not being strictly necessary for fixing the q35 bug, reducing the
list of user_creatable=true devices will help us be more
confident when building the q35 whitelist.

xen: We also have a hack at xen_set_dynamic_sysbus(), that sets
has_dynamic_sysbus=true at runtime when using the Xen
accelerator. This hack is only used to allow xen-backend devices
to be dynamically plugged/unplugged.

This means today we can use -device with the following 22 device
types, that are the ones compiled into the qemu-system-x86_64 and
qemu-system-i386 binaries:

* allwinner-ahci
* amd-iommu
* cfi.pflash01
* esp
* fw_cfg_io
* fw_cfg_mem
* generic-sdhci
* hpet
* intel-iommu
* ioapic
* isabus-bridge
* kvmclock
* kvm-ioapic
* kvmvapic
* SUNW,fdtwo
* sysbus-ahci
* sysbus-fdc
* sysbus-ohci
* unimplemented-device
* virtio-mmio
* xen-backend
* xen-sysdev

This patch adds user_creatable=true explicitly to those devices,
temporarily, just to keep 100% compatibility with existing
behavior of q35. Subsequent patches will remove
user_creatable=true from the devices that are really not meant to
user-creatable on any machine, and remove the FIXME comment from
the ones that are really supposed to be user-creatable. This is
being done in separate patches because we still don't have an
obvious list of devices that will be whitelisted by q35, and I
would like to get each device reviewed individually.

Eduardo Habkost e90f2a8c3e qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.

When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.

Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

Except for code comments, changes were generated using the
following Coccinelle patch:

Stefano Stabellini 1ff7c5986a xen/mapcache: store dma information in revmapcache entries for debugging
The Xen mapcache is able to create long term mappings, they are called
"locked" mappings. The third parameter of the xen_map_cache call
specifies if a mapping is a "locked" mapping.

>From the QEMU point of view there are two kinds of long term mappings:

[a] device memory mappings, such as option roms and video memory
[b] dma mappings, created by dma_memory_map & friends

After certain operations, ballooning a VM in particular, Xen asks QEMU
kindly to destroy all mappings. However, certainly [a] mappings are
present and cannot be removed. That's not a problem as they are not
affected by balloonning. The *real* problem is that if there are any
mappings of type [b], any outstanding dma operations could fail. This is
a known shortcoming. In other words, when Xen asks QEMU to destroy all
mappings, it is an error if any [b] mappings exist.

However today we have no way of distinguishing [a] from [b]. Because of
that, we cannot even print a decent warning.

This patch introduces a new "dma" bool field to MapCacheRev entires, to
remember if a given mapping is for dma or is a long term device memory
mapping. When xen_invalidate_map_cache is called, we print a warning if
any [b] mappings exist. We ignore [a] mappings.

Mappings created by qemu_map_ram_ptr are assumed to be [a], while
mappings created by address_space_map->qemu_ram_ptr_length are assumed
to be [b].

The goal of the patch is to make debugging and system understanding
easier.

Greg Kurz 7a95434e0c 9pfs: local: forbid client access to metadata (CVE-2017-7493)
When using the mapped-file security mode, we shouldn't let the client mess
with the metadata. The current code already tries to hide the metadata dir
from the client by skipping it in local_readdir(). But the client can still
access or modify it through several other operations. This can be used to
escalate privileges in the guest.

Affected backend operations are:
- local_mknod()
- local_mkdir()
- local_open2()
- local_symlink()
- local_link()
- local_unlinkat()
- local_renameat()
- local_rename()
- local_name_to_path()

Other operations are safe because they are only passed a fid path, which
is computed internally in local_name_to_path().

This patch converts all the functions listed above to fail and return
EINVAL when being passed the name of the metadata dir. This may look
like a poor choice for errno, but there's no such thing as an illegal
path name on Linux and I could not think of anything better.

This fixes CVE-2017-7493.

Stefan Hajnoczi 2f77ec7390 ppc patch queue for 2017-05-11
This pull request supersedes the one from yesterday (20170510), fixing
 an important style bug in one patch, and adding an extra couple of
 simple patches.
 
 Highlights of this set:
   * Some fixes for POWER9
   * TCG support for POWER9 radix MMU
   * VGA rom for Mac machine types
   * Fixes for the XICS interrupt controller
   * MTTCG support for ppc targets
 
 As suggested by Paolo, I've tried to add the Docker tests to my
 standard pre-pull-request tests.  I haven't wholly suceeded; this has
 been tested with some of the Docker images, but others I haven't
 managed due to problems that as best I can tell are not due to
 problems in this patch series.  I'll continue working on this for
 future pull requests.  Specifically, 'travis', 'fedora', and 'centos6'
 seem to work.  'min-glib' jammed while gtesting moxie, which seems
 very unlikely to be caused by this series.  'ubuntu', 'debian' and
 'debian-bootstrap' hit build errors almost immediately that look like
 problems with the container configuration, and 'debian-*-cross' hit
 build errors later on which also look like missing dependencies from
 the container.

Thomas Huth aa612b364e hw/usb/dev-serial: Do not try to set vendorid or productid properties
When starting QEMU with the legacy USB serial device like this:

 qemu-system-x86_64 -usbdevice serial:vendorid=0x1234:stdio

it currently aborts since the vendorid property does not exist
anymore (it has been removed by commit f29783f72e):

 Unexpected error in object_property_find() at qemu/qom/object.c:1008:

(and simplify the code also a little bit this way).

Ladi Prosek 99f9aeba5d xhci: relax link check

Ladi Prosek 66849dcfbe usb-hub: clear PORT_STAT_SUSPEND on wakeup
The spec says:

  Suspend: (PORT_SUSPEND) This field indicates whether or not the device
  on this port is suspended. Setting this field causes the device to
  suspend by not propagating bus traffic downstream. This field may be
  reset by a request or by resume signaling from the device attached to
  the port.

I can't find any specific statement like "the PORT_SUSPEND field is reset
automatically on remote wakeup", but without this patch, the only way to
reset it is via the ClearPortFeature request so the ".. or by resume
signaling from the device" clause is clearly not implemented on the remote
wakeup path.

The default xhci Windows driver does not issue the ClearPortFeature request
and suspended devices attached to a hub don't properly get out of the
suspended state. Interestingly, the default uhci Windows driver *does*
issue the ClearPortFeature request and does not exhibit this problem.
