The problem is that vfio work introduced dynamic memory region

The reset handler for DRCs attempts several state transitions which are
subject to various checks and restrictions. But at reset time we know
there is no guest, so we can ignore most of the usual sequencing rules and
just set the DRC back to a known state. In fact, it's safer to do so.
The existing code also has several redundant checks for
drc->awaiting_release inside a block which has already tested that. This
patch removes those and sets the DRC to a fixed initial state based only
on whether a device is currently plugged or not.
With DRCs correctly reset to a state based on device presence, we don't
need to force state transitions as cold plugged devices are processed.
This allows us to remove all the callers of the set_*_state() methods from

The 'signalled' field in the DRC appears to be entirely a torturous
workaround for the fact that PCI devices were started in UNISOLATED state
for unclear reasons.
1) 'signalled' is already meaningless for logical (so far, all non PCI)
DRCs. It's always set to true (at least at any point it might be tested),
and can't be assigned any real meaning due to the way signalling works for
logical DRCs.
2) For PCI DRCs, the only time signalled would be false is when non-zero
functions of a multifunction device are hotplugged, followed by function
zero (the other way around is explicitly not permitted). In that case the
secondary function DRCs are attached, but the notification isn't sent to
the guest until function 0 is plugged.
3) signalled being false is used to allow a DRC detach to switch mode
back to ISOLATED state, which allows a secondary function to be hotplugged
then unplugged with function 0 never inserted. Without this a secondary
function starting in UNISOLATED state couldn't be detached again without
function 0 being inserted, all the functions configured by the guest, then
sent back to ISOLATED state.
4) But now that PCI DRCs start in ISOLATED state, there's nothing to be
done. If the guest doesn't get the notification, it won't switch the
device to UNISOLATED state, so nothing prevents it from being unplugged.
If the guest does move it to UNISOLATED state without the signal (due to
a manual drmgr call, for instance) then it really isn't safe to unplug it.
So, this patch removes the signalled variable and all code related to it.

Commit 5bc8d26de2 ("spapr: allocate the ICPState object from under

This is an improvement since we no longer allocate ICPState objects
that will never be used. But it has the side-effect of breaking
migration of older machine types from older QEMU versions.
This patch allows spapr to register dummy "icp/server" entries to vmstate.
These entries use a dedicated VMStateDescription that can swallow and
discard state of an incoming migration stream, and that don't send anything
on outgoing migration.
As for real ICPState objects, the instance_id is the cpu_index of the
corresponding vCPU, which happens to be equal to the generated instance_id
of older machine types.
The machine can unregister/register these entries when CPUs are dynamically
plugged/unplugged.
This is only available for pseries-2.9 and older machines, thanks to a
compat property.

The ICPState objects are currently registered to vmstate as qdev objects.
Their instance ids are hence computed automatically in the migration code,
and thus depends on the order the CPU cores were plugged.
If the destination had its CPU cores plugged in a different order than the
source, then ICPState objects will have different instance_ids and load
the wrong state.
Since CPU objects have a reliable cpu_index which is already used as
instance_id in vmstate, let's use it for ICPState as well.
Please note that this doesn't break migration. Older machine types used to
allocate and realize all ICPState objects at machine init time, for the whole
lifetime of the machine. The qdev instance ids are thus 0,1,2... nr_servers
and happen to map to the vCPU indexes.

Migrating between different CPU versions is a bit complicated for ppc.
A long time ago, we ensured identical CPU versions at either end by
checking the PVR had the same value. However, this breaks under KVM
HV, because we always have to use the host's PVR - it's not
virtualized. That would mean we couldn't migrate between hosts with
different PVRs, even if the CPUs are close enough to compatible in
practice (sometimes identical cores with different surrounding logic
have different PVRs, so this happens in practice quite often).
So, we removed the PVR check, but instead checked that several flags
indicating supported instructions matched. This turns out to be a bad
idea, because those instruction masks are not architected information, but
essentially a TCG implementation detail. So changes to qemu internal CPU
modelling can break migration - this happened between qemu-2.6 and
qemu-2.7. That was addressed by 146c11f1 "target-ppc: Allow eventual
removal of old migration mistakes".
Now, verification of CPU compatibility across a migration basically doesn't
happen. We simply ignore the PVR of the incoming migration, and hope the
cpu on the destination is close enough to work.
Now that we've cleaned up handling of processor compatibility modes
for pseries machine type, we can do better. For new machine types
(pseries-2.10+) We allow migration if:
* The source and destination PVRs are for the same type of CPU, as
determined by CPU class's pvr_match function
OR * When the source was in a compatibility mode, and the destination CPU
supports the same compatibility mode
For older machine types we retain the existing behaviour - current CAS
code will usually set a compat mode which would break backwards
migration if we made them use the new behaviour. [Fixed from an
earlier version by Greg Kurz].

Currently, the CPU compatibility mode is set when the cpu is initialized,
then again when the guest negotiates features. This means if a guest
negotiates a compatibility mode, then reboots, that compatibility mode
will be retained across the reset.
Usually that will get overridden when features are negotiated on the next
boot, but it's still not really correct. This patch moves the initial set
up of the compatibility mode from cpu init to reset time. The mode *is*
retained if the reboot was caused by the feature negotiation (it might
be important in that case, though it's unlikely).

Server class POWER CPUs have a "compat" property, which is used to set the
backwards compatibility mode for the processor. However, this only makes
sense for machine types which don't give the guest access to hypervisor
privilege - otherwise the compatibility level is under the guest's control.
To reflect this, this removes the CPU 'compat' property and instead
creates a 'max-cpu-compat' property on the pseries machine. Strictly
speaking this breaks compatibility, but AFAIK the 'compat' option was
never (directly) used with -device or device_add.
The option was used with -cpu. So, to maintain compatibility, this
patch adds a hack to the cpu option parsing to strip out any compat
options supplied with -cpu and set them on the machine property
instead of the now deprecated cpu property.

It is hard to analyze trace logs with multiple virtio-blk devices
because none of the trace events include the VirtIODevice *vdev.
This patch adds vdev so it's clear which device a request is associated
with.
I considered using VirtIOBlock *s instead but VirtIODevice *vdev is more
general and may be correlated with generic virtio trace events like
virtio_set_status.

Contrary to what is written in the comment, a buggy guest can misconfigure
the transport buffers and pdu_marshal() may return an error. If this ever
happens, it is up to the transport layer to handle the situation (9P is
transport agnostic).
This fixes Coverity issue CID1348518.

Implement xen_9pfs_disconnect by unbinding the event channels. On
xen_9pfs_free, call disconnect if any event channels haven't been
disconnected.
If the frontend misconfigured the buffers set the backend to "Closing"
and disconnect it. Misconfigurations include requesting a read of more
bytes than available on the ring buffer, or claiming to be writing more
data than available on the ring buffer.

The 9P protocol is transport agnostic: if the guest misconfigured the
buffers, the best we can do is to set the broken flag on the device.
Signed-off-by: Greg Kurz <groug@kaod.org>
The 9p spec at http://man.cat-v.org/plan_9/5/intro reads:
"Each 9P message begins with a four-byte size field specify-
ing the length in bytes of the complete message including
the four bytes of the size field itself. The next byte is
the message type, one of the constants in the enumeration in
the include file <fcall.h>. The next two bytes are an iden-
tifying tag, described below."
ie, each message starts with a 7-byte long header.
The core 9P code already assumes this pretty much everywhere. This patch
does the following:
- makes the assumption explicit in the common 9p.h header, since it isn't
related to the transport
- open codes the header size in handle_9p_output() and hardens the sanity
check on the space needed for the reply message

In mapped security modes, files are created with very restrictive
permissions (600 for files and 700 for directories). This makes
file sharing between virtual machines and users on the host rather
complicated. Imagine eg. a group of users that need to access data
produced by processes on a virtual machine. Giving those users access
to the data will be difficult since the group access mode is always 0.
This patch makes the default mode for both files and directories
configurable. Existing setups that don't know about the new parameters
keep using the current secure behavior.

In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug,
but it's actually the best we can do. Especially in these cases a verbose
error message is required.
Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:
# lsusb -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
Device: ID 1199:9071 Sierra Wireless, Inc.
idVendor 0x1199 Sierra Wireless, Inc.
idProduct 0x9071
bNumInterfaces 5
bInterfaceNumber 0
bInterfaceNumber 2
bInterfaceNumber 3
bInterfaceNumber 8
bInterfaceNumber 10
In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.
This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.

The getter and setter of TYPE_APIC_COMMON property "id" are
apic_common_get_id() and apic_common_set_id().
apic_common_get_id() reads either APICCommonState member uint32_t
initial_apic_id or uint8_t id into an int64_t local variable. It then
passes this variable to visit_type_int().
apic_common_set_id() uses visit_type_int() to read the value into a
local variable, which it then assigns both to initial_apic_id and id.
While the state backing the property is two unsigned members, 8 and 32
bits wide, the actual visitor is 64 bits signed.
Change getter and setter to use visit_type_uint32(). Then everything's
uint32_t, except for @id.

There are a few empty lines added to improve code reading/style.

[Commit message tweaked]
Signed-off-by: Markus Armbruster <armbru@redhat.com>
Use the actual unsigned integer type name.
The type name change impacts the following externally visible area:
* vl.c's machine_help_func() puts it in help for -machine NAME,help.
* QMP command qom-list exposes it in ObjectPropertyInfo member @type.
* QMP command device-list-properties exposes it in DevicePropertyInfo
member @type.
