d9b6964039 Fix tulip breakage
The tulip network driver in a qemu-system-hppa emulation is broken in
the sense that bigger network packages aren't received any longer and
thus even running e.g. "apt update" inside the VM fails.

The breakage was introduced by commit 8ffb7265af ("check frame size and
r/w data length") which added checks to prevent accesses outside of the
rx/tx buffers.

But the new checks were implemented wrong. The variable rx_frame_len
counts backwards, from rx_frame_size down to zero, and the variable len
is never bigger than rx_frame_len, so accesses just can't happen and the
checks are unnecessary.
On the contrary the checks now prevented bigger packages to be moved
into the rx buffers.

This patch reverts the wrong checks and were sucessfully tested with a
qemu-system-hppa emulation.

Fixes: 8ffb7265af ("check frame size and r/w data length")

e22f0603fb virtio-net: reference implementation of hash report
Suggest VIRTIO_NET_F_HASH_REPORT if specified in device
parameters.
If the VIRTIO_NET_F_HASH_REPORT is set,
the device extends configuration space. If the feature
is negotiated, the packet layout is extended to
accomodate the hash information. In this case deliver
packet's hash value and report type in virtio header
extension.
Use for configuration the same procedure as already
used for RSS. We add two fields in rss_data that
controls what the device does with the calculated hash
if rss_data.enabled is set. If field 'populate' is set
the hash is set in the packet, if field 'redirect' is
set the hash is used to decide the queue to place the
packet to.

9fc7fc4d39 qom: Less verbose object_initialize_child()
All users of object_initialize_child() pass the obvious child size
argument.  Almost all pass &error_abort and no properties.  Tiresome.

Rename object_initialize_child() to
object_initialize_child_with_props() to free the name.  New
convenience wrapper object_initialize_child() automates the size
argument, and passes &error_abort and no properties.

Rename object_initialize_childv() to
object_initialize_child_with_propsv() for consistency.

8e5c952b37 hw: Remove unnecessary DEVICE() cast
The DEVICE() macro is defined as:

  #define DEVICE(obj) OBJECT_CHECK(DeviceState, (obj), TYPE_DEVICE)

which expands to:

  ((DeviceState *)object_dynamic_cast_assert((Object *)(obj), (name),
                                             __FILE__, __LINE__,

This assertion can only fail when @obj points to something other
than its stated type, i.e. when we're in undefined behavior country.

Remove the unnecessary DEVICE() casts when we already know the
pointer is of DeviceState type.

Patch created mechanically using spatch with this script:

b69c3c21a5 qdev: Unrealize must not fail
Devices may have component devices and buses.

Device realization may fail.  Realization is recursive: a device's
realize() method realizes its components, and device_set_realized()
realizes its buses (which should in turn realize the devices on that
bus, except bus_set_realized() doesn't implement that, yet).

When realization of a component or bus fails, we need to roll back:
unrealize everything we realized so far.  If any of these unrealizes
failed, the device would be left in an inconsistent state.  Must not
happen.

device_set_realized() lets it happen: it ignores errors in the roll
back code starting at label child_realize_fail.

Since realization is recursive, unrealization must be recursive, too.
But how could a partly failed unrealize be rolled back?  We'd have to
re-realize, which can fail.  This design is fundamentally broken.

device_set_realized() does not roll back at all.  Instead, it keeps
unrealizing, ignoring further errors.

It can screw up even for a device with no buses: if the lone
dc->unrealize() fails, it still unregisters vmstate, and calls
listeners' unrealize() callback.

bus_set_realized() does not roll back either.  Instead, it stops
unrealizing.

Fortunately, no unrealize method can fail, as we'll see below.

To fix the design error, drop parameter @errp from all the unrealize
methods.

Any unrealize method that uses @errp now needs an update.  This leads
us to unrealize() methods that can fail.  Merely passing it to another
unrealize method cannot cause failure, though.  Here are the ones that
do other things with @errp:

* virtio_serial_device_unrealize()

  Fails when qbus_set_hotplug_handler() fails, but still does all the
  other work.  On failure, the device would stay realized with its
  resources completely gone.  Oops.  Can't happen, because
  qbus_set_hotplug_handler() can't actually fail here.  Pass
  &error_abort to qbus_set_hotplug_handler() instead.

* hw/ppc/spapr_drc.c's unrealize()

  Fails when object_property_del() fails, but all the other work is
  already done.  On failure, the device would stay realized with its
  vmstate registration gone.  Oops.  Can't happen, because
  object_property_del() can't actually fail here.  Pass &error_abort
  to object_property_del() instead.

* spapr_phb_unrealize()

  Fails and bails out when remove_drcs() fails, but other work is
  already done.  On failure, the device would stay realized with some
  of its resources gone.  Oops.  remove_drcs() fails only when
  chassis_from_bus()'s object_property_get_uint() fails, and it can't
  here.  Pass &error_abort to remove_drcs() instead.

Therefore, no unrealize method can fail before this patch.

device_set_realized()'s recursive unrealization via bus uses
object_property_set_bool().  Can't drop @errp there, so pass
&error_abort.

We similarly unrealize with object_property_set_bool() elsewhere,
always ignoring errors.  Pass &error_abort instead.

Several unrealize methods no longer handle errors from other unrealize
methods: virtio_9p_device_unrealize(),
virtio_input_device_unrealize(), scsi_qdev_unrealize(), ...
Much of the deleted error handling looks wrong anyway.

One unrealize methods no longer ignore such errors:
usb_ehci_pci_exit().

Several realize methods no longer ignore errors when rolling back:
v9fs_device_realize_common(), pci_qdev_unrealize(),
spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(),
virtio_device_realize().

d2623129a7 qom: Drop parameter @errp of object_property_add() & friends
The only way object_property_add() can fail is when a property with
the same name already exists.  Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.

Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent.  Parentage is
also under program control, so this is a programming error, too.

We have a bit over 500 callers.  Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.

The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.

Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.  ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.

When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.

Drop parameter @errp and assert the preconditions instead.

There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification".  Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

a13f20422d e1000: Don't run e1000_instance_init() twice
QOM object initialization runs .instance_init() for the type and all
its supertypes; see object_init_with_type().

Both TYPE_E1000_BASE and its concrete subtypes set .instance_init() to
e1000_instance_init().  For the concrete subtypes, it duly gets run
twice.  The second run fails, but the error gets ignored (a later
commit will change that).

Remove it from the subtypes.

ddfb0baaf2 qom: Clean up inconsistent use of gchar * vs. char *
Uses of gchar * in qom/object.h:

* ObjectProperty member @name

  Functions that take a property name argument all use char *.  Change
  the member to match.

* ObjectProperty member @type

  Functions that take a property type argument or return it all use
  char *.  Change the member to match.

* ObjectProperty member @description

  Functions that take a property description argument all use char *.
  Change the member to match.

* object_resolve_path_component() parameter @part

  Path components are property names.  Most callers pass char *
  arguments.  Change the parameter to match.  Adjust the few callers
  that pass gchar * to pass char *.

* Return value of object_get_canonical_path_component(),
  object_get_canonical_path()

  Most callers convert their return values right back to char *.
  Change the return value to match.  Adjust the few callers where that
  would add a conversion to gchar * to use char * instead.

b88fb1247b hw/net/allwinner-sun8i-emac.c: Fix REG_ADDR_HIGH/LOW reads
Coverity points out (CID 1421926) that the read code for
REG_ADDR_HIGH reads off the end of the buffer, because it does a
32-bit read from byte 4 of a 6-byte buffer.

The code also has an endianness issue for both REG_ADDR_HIGH and
REG_ADDR_LOW, because it will do the wrong thing on a big-endian
host.

Rewrite the read code to use ldl_le_p() and lduw_le_p() to fix this;
the write code is not incorrect, but for consistency we make it use
stl_le_p() and stw_le_p().

a43790f2f6 hw/net/i82596.c: Avoid reading off end of buffer in i82596_receive()
The i82596_receive() function attempts to pass the guest a buffer
which is effectively the concatenation of the data it is passed and a
4 byte CRC value.  However, rather than implementing this as "write
the data; then write the CRC" it instead bumps the length value of
the data by 4, and writes 4 extra bytes from beyond the end of the
buffer, which it then overwrites with the CRC.  It also assumed that
we could always fit all four bytes of the CRC into the final receive
buffer, which might not be true if the CRC needs to be split over two
receive buffers.

Calculate separately how many bytes we need to transfer into the
guest's receive buffer from the source buffer, and how many we need
to transfer from the CRC work.

We add a count 'bufsz' of the number of bytes left in the source
buffer, which we use purely to assert() that we don't overrun.

Spotted by Coverity (CID 1419396) for the specific case when we end
up using a local array as the source buffer.

The command is 32-bit, but we are loading the 16 upper bits with
the 'get_uint16(s->scb + 2)' call.

Once shifted by 16, the command bits match the status bits:

- Command
  Bit 31 ACK-CX   Acknowledges that the CU completed an Action Command.
  Bit 30 ACK-FR   Acknowledges that the RU received a frame.
  Bit 29 ACK-CNA  Acknowledges that the Command Unit became not active.
  Bit 28 ACK-RNR  Acknowledges that the Receive Unit became not ready.

- Status
  Bit 15 CX       The CU finished executing a command with its I(interrupt) bit set.
  Bit 14 FR       The RU finished receiving a frame.
  Bit 13 CNA      The Command Unit left the Active state.
  Bit 12 RNR      The Receive Unit left the Ready state.

Add the SCB_COMMAND_ACK_MASK definition to simplify the code.

c2279bd0a1 dp8393x: Don't stop reception upon RBE interrupt assertion
Section 3.4.7 of the datasheet explains that,

    The RBE bit in the Interrupt Status register is set when the
    SONIC finishes using the second to last receive buffer and reads
    the last RRA descriptor. Actually, the SONIC is not truly out of
    resources, but gives the system an early warning of an impending
    out of resources condition.

RBE does not mean actual receive buffer exhaustion, and reception should
not be stopped. This is important because Linux will not check and clear
the RBE interrupt until it receives another packet. But that won't
happen if can_receive returns false. This bug causes the SONIC to become

083e21bbdd dp8393x: Don't reset Silicon Revision register
The jazzsonic driver in Linux uses the Silicon Revision register value
to probe the chip. The driver fails unless the SR register contains 4.
Unfortunately, reading this register in QEMU usually returns 0 because
the s->regs[] array gets wiped after a software reset.

d9fae13196 dp8393x: Clear descriptor in_use field to release packet
When the SONIC receives a packet into the last available descriptor, it
retains ownership of that descriptor for as long as necessary.

Section 3.4.7 of the datasheet says,

    When the system appends more descriptors, the SONIC releases ownership
    of the descriptor after writing 0000h to the RXpkt.in_use field.

The packet can now be processed by the host, so raise a PKTRX interrupt,
just like the normal case.

350e7d9a77 dp8393x: Pad frames to word or long word boundary
The existing code has a bug where the Remaining Buffer Word Count (RBWC)
is calculated with a truncating division, which gives the wrong result
for odd-sized packets.

Section 1.4.1 of the datasheet says,

    Once the end of the packet has been reached, the serializer will
    fill out the last word (16-bit mode) or long word (32-bit mode)
    if the last byte did not end on a word or long word boundary
    respectively. The fill byte will be 0FFh.

Section 3.4.1 of the datasheet says,

    The alignment of the RRA is confined to either word or long word
    boundaries, depending upon the data width mode. In 16-bit mode,
    the RRA must be aligned to a word boundary (A0 is always zero)
    and in 32-bit mode, the RRA is aligned to a long word boundary
    (A0 and A1 are always zero).

This constraint has been implemented for 16-bit mode; implement it

The DP83932 and DP83934 have 32 data lines. The datasheet says,

    Data Bus: These bidirectional lines are used to transfer data on the
    system bus. When the SONIC is a bus master, 16-bit data is transferred
    on D15-D0 and 32-bit data is transferred on D31-D0. When the SONIC is
    accessed as a slave, register data is driven onto lines D15-D0.
    D31-D16 are held TRI-STATE if SONIC is in 16-bit mode. If SONIC is in
    32-bit mode, they are driven, but invalid.

Always use 32-bit accesses both as bus master and bus slave.

Force the MSW to zero in bus master mode.

This gets the Linux 'jazzsonic' driver working, and avoids the need for
prior hacks to make the NetBSD 'sn' driver work.

19f7034773 Avoid address_space_rw() with a constant is_write argument
The address_space_rw() function allows either reads or writes
depending on the is_write argument passed to it; this is useful
when the direction of the access is determined programmatically
(as for instance when handling the KVM_EXIT_MMIO exit reason).
Under the hood it just calls either address_space_write() or
address_space_read_full().

We also use it a lot with a constant is_write argument, though,
which has two issues:
 * when reading "address_space_rw(..., 1)" this is less
   immediately clear to the reader as being a write than
   "address_space_write(...)"
 * calling address_space_rw() bypasses the optimization
   in address_space_read() that fast-paths reads of a
   fixed length

1bbd1511b6 Clean-ups: qom-ify serial and remove QDEV_PROP_PTR
Hi,
 
 QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
 me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
 the pointer points to an Object.
 
 There are a few places where such substitution isn't possible. For
 those places, it seems reasonable to use a specific setter method
 instead, and keep the user_creatable = false. In other places,
 proper usage of qdev or other facilies is the solution.
 
 The serial code wasn't converted to qdev, which makes it a bit more
 archaic to deal with. Let's convert it first, so we can more easily
 embed it from other devices, and re-export some properties and drop
 QDEV_PROP_PTR usage.

Clean-ups: qom-ify serial and remove QDEV_PROP_PTR

Hi,

QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
the pointer points to an Object.

There are a few places where such substitution isn't possible. For
those places, it seems reasonable to use a specific setter method
instead, and keep the user_creatable = false. In other places,
proper usage of qdev or other facilies is the solution.

The serial code wasn't converted to qdev, which makes it a bit more
archaic to deal with. Let's convert it first, so we can more easily
embed it from other devices, and re-export some properties and drop
QDEV_PROP_PTR usage.

5a0948d36c net/virtio: Fix failover error handling crash bugs
Functions that take an Error ** parameter to pass an error to the
caller expect the parameter to point to null.
failover_replug_primary() violates this precondition in several
places:

* After qemu_opts_from_qdict() failed, *errp is no longer null.
  Passing it to error_setg() is wrong, and will trip the assertion in
  error_setv().  Messed up in commit 150ab54aa6 "net/virtio: fix
  re-plugging of primary device".  Simply drop the error_setg().

* Passing @errp to qemu_opt_set_bool(), hotplug_handler_pre_plug(),
  and hotplug_handler_plug() is wrong.  If one of the first two fails,
  *errp is no longer null.  Risks tripping the same assertion.
  Moreover, continuing after such errors is unsafe.  Messed up in
  commit 9711cd0dfc "net/virtio: add failover support".  Fix by
  handling each error properly.

failover_replug_primary() crashes when passed a null @errp.  Also
messed up in commit 9711cd0dfc.  This bug can't bite as no caller
actually passes null.  Fix it anyway.

If n->primary_dev is null on entering failover_replug_primary(), @pdev

n->primary_dev later is useless.  It can't actually be null, because

.dev_unplug_pending is set up by virtio-net code indepent of failover
support was set for the device or not. This gives a wrong result when
we check for existing primary devices in migration code.

Fix this by actually calling dev_unplug_pending() instead of just
checking if the function pointer was set. When the feature was not
negotiated dev_unplug_pending() will always return false. This prevents
us from going into the wait-unplug state when there's no primary device
present.

6623d21445 net/cadence_gem: Set PHY autonegotiation restart status
The Linux kernel PHY driver sets AN_RESTART in the BMCR of the
PHY when autonegotiation is started.
Recently the kernel started to read back the PHY's AN_RESTART
bit and now checks whether the autonegotiation is complete and
the bit was cleared [1]. Otherwise the link status is down.

The emulated PHY needs to clear AN_RESTART immediately to inform
the kernel driver about the completion of autonegotiation phase.

9711cd0dfc net/virtio: add failover support
This patch adds support to handle failover device pairs of a virtio-net
device and a (vfio-)pci device, where the virtio-net acts as the standby
device and the (vfio-)pci device as the primary.

The general idea is that we have a pair of devices, a (vfio-)pci and a
emulated (virtio-net) device. Before migration the vfio device is
unplugged and data flows to the emulated device, on the target side
another (vfio-)pci device is plugged in to take over the data-path. In the
guest the net_failover module will pair net devices with the same MAC
address.

To achieve this we need:

1. Provide a callback function for the should_be_hidden DeviceListener.
   It is called when the primary device is plugged in. Evaluate the QOpt
   passed in to check if it is the matching primary device. It returns
   if the device should be hidden or not.
   When it should be hidden it stores the device options in the VirtioNet
   struct and the device is added once the VIRTIO_NET_F_STANDBY feature is
   negotiated during virtio feature negotiation.

   If the virtio-net devices are not realized at the time the (vfio-)pci
   devices are realized, we need to connect the devices later. This way
   we make sure primary and standby devices can be specified in any
   order.

2. Register a callback for migration status notifier. When called it
   will unplug its primary device before the migration happens.

3. Register a callback for the migration code that checks if a device
   needs to be unplugged from the guest.

7788c3f2e2 virtio-net: prevent offloads reset on migration
Currently offloads disabled by guest via the VIRTIO_NET_CTRL_GUEST_OFFLOADS_SET
command are not preserved on VM migration.
Instead all offloads reported by guest features (via VIRTIO_PCI_GUEST_FEATURES)
get enabled.
What happens is: first the VirtIONet::curr_guest_offloads gets restored and offloads
are getting set correctly:

 #0  qemu_set_offload (nc=0x555556a11400, csum=1, tso4=0, tso6=0, ecn=0, ufo=0) at net/net.c:474

However later on the features are getting restored, and offloads get reset to
everything supported by features:

Fix this by preserving the state in saved_guest_offloads field and
pushing out offload initialization to the new post load hook.

34ea023d4b net: add tulip (dec21143) driver
This adds the basic functionality to emulate a Tulip NIC.

Implemented are:

- RX and TX functionality
- Perfect Frame Filtering
- Big/Little Endian descriptor support
- 93C46 EEPROM support
- LXT970 PHY

Not implemented, mostly because i had no OS using these functions:

- Imperfect frame filtering
- General Purpose Timer
- Transmit automatic polling
- Boot ROM support
- SIA interface
- Big/Little Endian data buffer conversion

Successfully tested with the following Operating Systems:

- MSDOS with Microsoft Network Client 3.0 and DEC ODI drivers
- HPPA Linux
- Windows XP
- HP-UX

b01422622b ptimer: Rename ptimer_init() to ptimer_init_with_bh()
Currently the ptimer design uses a QEMU bottom-half as its
mechanism for calling back into the device model using the
ptimer when the timer has expired. Unfortunately this design
is fatally flawed, because it means that there is a lag
between the ptimer updating its own state and the device
callback function updating device state, and guest accesses
to device registers between the two can return inconsistent
device state.

We want to replace the bottom-half design with one where
the guest device's callback is called either immediately
(when the ptimer triggers by timeout) or when the device
model code closes a transaction-begin/end section (when the
ptimer triggers because the device model changed the
ptimer's count value or other state). As the first step,
rename ptimer_init() to ptimer_init_with_bh(), to free up
the ptimer_init() name for the new API. We can then convert
all the ptimer users away from ptimer_init_with_bh() before

7678b74a94 spapr: Replace spapr_vio_qirq() helper with spapr_vio_irq_pulse() helper
Every caller of spapr_vio_qirq() immediately calls qemu_irq_pulse() with
the result, so we might as well just fold that into the helper.

65da914295 hw/net/xilinx_axi: Use object_initialize_child for correct ref. counting
As explained in commit aff39be0ed:

  Both functions, object_initialize() and object_property_add_child()
  increase the reference counter of the new object, so one of the
  references has to be dropped afterwards to get the reference
  counting right. Otherwise the child object will not be properly
  cleaned up when the parent gets destroyed.
  Thus let's use now object_initialize_child() instead to get the
  reference counting here right.

88e1b59ee3 Set ENET_BD_BDU in I.MX FEC controller
This commit properly sets the ENET_BD_BDU flag once the emulated FEC controller
has finished processing the last descriptor. This is done for both transmit
and receive descriptors.

This allows the QNX 7.0.0 BSP for the Sabrelite board (which can be
found at http://blackberry.qnx.com/en/developers/bsp) to properly
control the FEC. Without this patch, the BSP ethernet driver will never
re-use FEC descriptors, as the unset ENET_BD_BDU flag will cause
it to believe that the descriptors are still in use by the NIC.

Note that Linux does not appear to use this field at all, and is
unaffected by this patch.

Without this patch, QNX will think that the NIC is still processing its
transaction descriptors, and won't send any more data over the network.

For reference:

On page 1192 of the I.MX 6DQ reference manual revision (Rev. 5, 06/2018),
which can be found at https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-6-processors/i.mx-6quad-processors-high-performance-3d-graphics-hd-video-arm-cortex-a9-core:i.MX6Q?&tab=Documentation_Tab&linkline=Application-Note

the 'BDU' field is described as follows for the 'Enhanced transmit
buffer descriptor':

'Last buffer descriptor update done. Indicates that the last BD data has been updated by
uDMA. This field is written by the user (=0) and uDMA (=1).'

The same description is used for the receive buffer descriptor.

54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

In my "build everything" tree, changing hw/qdev-properties.h triggers

objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h.  Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

Its instance struct is IOMMUMemoryRegion, and its first member is a
MemoryRegion.  Correct.  Its class struct is IOMMUMemoryRegionClass,
and its first member is a DeviceClass.  Wrong.  Messed up when commit
1221a47467 introduced the QOM type.  It even included hw/qdev-core.h
just for that.

TYPE_MEMORY_REGION doesn't bother to define a class struct.  This is
fine, it simply defaults to its super-type TYPE_OBJECT's class struct
ObjectClass.  Changing IOMMUMemoryRegionClass's first member's type to
ObjectClass would be a minimal fix, if a bit brittle: if
TYPE_MEMORY_REGION ever acquired own class struct, we'd have to update
IOMMUMemoryRegionClass to use it.

Fix it the clean and robust way instead: give TYPE_MEMORY_REGION its
own class struct MemoryRegionClass now, and use it for
IOMMUMemoryRegionClass's first member.

Revert the include of hw/qdev-core.h, and fix the few files that have
come to rely on it.

78dd48df39 hw/net: fix vmxnet3 live migration
At some point vmxnet3 live migration stopped working and git-bisect
didn't help finding a working version.
The issue is the PCI configuration space is not being migrated
successfully and MSIX remains masked at destination.

Remove the migration differentiation between PCI and PCIe since
the logic resides now inside VMSTATE_PCI_DEVICE.
Remove also the VMXNET3_COMPAT_FLAG_DISABLE_PCIE based differentiation
since at 'realize' time is decided if the device is PCI or PCIe,
then the above macro is enough.

Use the opportunity to move to the standard VMSTATE_MSIX
instead of the deprecated SaveVMHandlers.

f46efa9b08 e1000: don't raise interrupt in pre_save()
We should not raise any interrupt after VM has been stopped but this
is what e1000 currently did when mit timer is active in
pre_save(). Fixing this by scheduling a timer in post_load() which can
make sure the interrupt was raised when VM is running.

09340f497e sunhme: ensure that RX descriptor ring overflow is indicated to client driver
On very busy networks connected via a tap interface, it is possible to overflow
the RX descriptor ring in the time between the client driver enabling the RX
MAC and finishing writing the final configuration to the NIC registers.

Ensure that we detect this condition and update the status register accordingly
to indicate an overflow has occurred (and the incoming packet dropped) in order
to prevent the client driver becoming confused.

944458b659 net/announce: Add optional ID
Previously there was a single instance of the timer used by
monitor triggered announces, that's OK, but when combined with the
previous change that lets you have announces for subsets of interfaces
it's a bit restrictive if you want to do different things to different
interfaces.

Add an 'id' field to the announce, and maintain a list of the
timers based on id.

This allows you to for example:
    a) Start an announce going on interface eth0 for a long time
    b) Start an announce going on interface eth1 for a long time
    c) Kill the announce on eth0 while leaving eth1 going.

a3434a2d56 xen: Import other xen/io/*.h
A Xen public header have been imported into QEMU (by
f65eadb639 "xen: import ring.h from xen"), but there are other header
that depends on ring.h which come from the system when building QEMU.

This patch resolves the issue of having headers from the system
importing a different copie of ring.h.

This patch is prompt by the build issue described in the previous
patch: 'Revert xen/io/ring.h of "Clean up a few header guard symbols"'

ring.h and the new imported headers are moved to
"include/hw/xen/interface" as those describe interfaces with a guest.

The imported headers are cleaned up a bit while importing them: some
part of the file that QEMU doesn't use are removed (description
of how to make hypercall in grant_table.h have been removed).

Other cleanup:
- xen-mapcache.c and xen-legacy-backend.c don't need grant_table.h.
- xenfb.c doesn't need event_channel.h.

427ceb0fec e1000: Never increment the RX undersize count register
In situations where e1000 receives an undersized Ethernet frame,
QEMU increments the emulated "Receive Undersize Count (RUC)"
register when padding the frame.

This is incorrect because this an expected scenario (e.g. with
VLAN tag stripping) and not an error. As such, QEMU should not
increment the emulated RUC.

e1000: set_ics 0, ICR 82, IMR 9d <- unmask interrupt and because 0x82&0x9d

To workaround this problem, simply delay flush queue. Also stop receiving
when timer is going to run.

dec9776049 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of cleanup-trace-events.pl.  Same funnies as in the
previous commit, of course.  Manually shorten its change to
linux-user/trace-events to */signal.c.

ce2918cbc3 spapr: Use CamelCase properly
The qemu coding standard is to use CamelCase for type and structure names,
and the pseries code follows that... sort of.  There are quite a lot of
places where we bend the rules in order to preserve the capitalization of
internal acronyms like "PHB", "TCE", "DIMM" and most commonly "sPAPR".

That was a bad idea - it frequently leads to names ending up with hard to
read clusters of capital letters, and means they don't catch the eye as
type identifiers, which is kind of the point of the CamelCase convention in
the first place.

In short, keeping type identifiers look like CamelCase is more important
than preserving standard capitalization of internal "words".  So, this
patch renames a heap of spapr internal type names to a more standard
CamelCase.

In addition to case changes, we also make some other identifier renames:
  VIOsPAPR* -> SpaprVio*
    The reverse word ordering was only ever used to mitigate the capital
    cluster, so revert to the natural ordering.
  VIOsPAPRVTYDevice -> SpaprVioVty
  VIOsPAPRVLANDevice -> SpaprVioVlan
    Brevity, since the "Device" didn't add useful information
  sPAPRDRConnector -> SpaprDrc
  sPAPRDRConnectorClass -> SpaprDrcClass
    Brevity, and makes it clearer this is the same thing as a "DRC"
    mentioned in many other places in the code

This is 100% a mechanical search-and-replace patch.  It will, however,
conflict with essentially any and all outstanding patches touching the
spapr code.

7c28b925b7 build: convert pci.mak to Kconfig
Instead of including the same list of devices for each target,
set CONFIG_PCI to true, and make the devices default to present
whenever PCI is available.  However, s390x does not want all the
PCI devices, so there is a separate symbol to enable them.

Done mostly with the following script:

  while read i; do
     i=${i%=y}; i=${i#CONFIG_}
     sed -i -e'/^config '$i'$/!b' -en \
            -e'a\' -e'    default y if PCI_DEVICES\' -e'    depends on PCI' \
          `grep -lw $i hw/*/Kconfig`
  done < default-configs/pci.mak

followed by replacing a few "depends on" clauses with "select"
whenever the symbol is not really related to PCI.

82f5181777 kconfig: introduce kconfig files

  for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do
    set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' `
    shift
    if test $# = 1; then
      cat >> $(dirname $1)/Kconfig << EOF
config ${i#CONFIG_}
    bool

EOF
      git add $(dirname $1)/Kconfig
    else
      echo $i $*
    fi
  done
  sed -i '$d' hw/*/Kconfig
  for i in hw/*; do
    if test -d $i && ! test -f $i/Kconfig; then
      touch $i/Kconfig
      git add $i/Kconfig
    fi
  done

Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
These symbols have to be added manually to the Kconfig files.

Kconfig.host and hw/Kconfig were created manually.

56f41de737 vhost-net-user: add stubs for when no virtio-net device is present
hw/net/vhost_net.c needs functions that are declared in net/vhost-user.c: the
vhost-user code is always compiled into QEMU, only the constructor
net_init_vhost_user is unreachable.  Also, net/vhost-user.c needs functions
declared in hw/virtio/vhost-stub.c even if no virtio device exists.

Break this dependency.  First, add a minimal version of net/vhost-user.c,
with no functionality and no dependency on vhost code.  Second, #ifdef out
the calls back to net/vhost-user.c from hw/net/vhost_net.c.

While at it, this patch fixes the CONFIG_VHOST_NET_USE*D* typo.

7b28c61524 vhost-net: move stubs to a separate file
There is no reason for CONFIG_VHOST_NET to be specific to a single target;
it is a host feature that can be add to all targets, as long as they support
the virtio-net device.  Currently CONFIG_VHOST_NET depends on CONFIG_KVM,
but ioeventfd support is present in the core memory API and works with
other accelerators as well.

As a first step, move the vhost-net stubs to a separate file.  Later, they
will become conditional on CONFIG_VIRTIO_NET, which is not available in .c
files.

f16c845ade ftgmac100: implement the new MDIO interface on Aspeed SoC
The PHY behind the MAC of an Aspeed SoC can be controlled using two
different MDC/MDIO interfaces. The same registers PHYCR (MAC60) and
PHYDATA (MAC64) are involved but they have a different layout.

BIT31 of the Feature Register (MAC40) controls which MDC/MDIO
interface is active.

2974e916df virtio-net: support RSC v4/v6 tcp traffic for Windows HCK
This commit adds implementation of RX packets
coalescing, compatible with requirements of Windows
Hardware compatibility kit.

The device enables feature VIRTIO_NET_F_RSC_EXT in
host features if it supports extended RSC functionality
as defined in the specification.
This feature requires at least one of VIRTIO_NET_F_GUEST_TSO4,
VIRTIO_NET_F_GUEST_TSO6. Windows guest driver acks
this feature only if VIRTIO_NET_F_CTRL_GUEST_OFFLOADS
is also present.

If the guest driver acks VIRTIO_NET_F_RSC_EXT feature,
the device coalesces TCPv4 and TCPv6 packets (if
respective VIRTIO_NET_F_GUEST_TSO feature is on,
populates extended RSC information in virtio header
and sets VIRTIO_NET_HDR_F_RSC_INFO bit in header flags.
The device does not recalculate checksums in the coalesced
packet, so they are not valid.

In this case:
All the data packets in a tcp connection are cached
to a single buffer in every receive interval, and will
be sent out via a timer, the 'virtio_net_rsc_timeout'
controls the interval, this value may impact the
performance and response time of tcp connection,
50000(50us) is an experience value to gain a performance
improvement, since the whql test sends packets every 100us,
so '300000(300us)' passes the test case, it is the default
value as well, tune it via the command line parameter
'rsc_interval' within 'virtio-net-pci' device, for example,
to launch a guest with interval set as '500000':

'virtio-net-pci,netdev=hostnet1,bus=pci.0,id=net1,mac=00,
guest_rsc_ext=on,rsc_interval=500000'

The timer will only be triggered if the packets pool is not empty,
and it'll drain off all the cached packets.

'NetRscChain' is used to save the segments of IPv4/6 in a
VirtIONet device.

A new segment becomes a 'Candidate' as well as it passed sanity check,
the main handler of TCP includes TCP window update, duplicated
ACK check and the real data coalescing.

An 'Candidate' segment means:
1. Segment is within current window and the sequence is the expected one.
2. 'ACK' of the segment is in the valid window.

Sanity check includes:
1. Incorrect version in IP header
2. An IP options or IP fragment
3. Not a TCP packet
4. Sanity size check to prevent buffer overflow attack.
5. An ECN packet

Even though, there might more cases should be considered such as
ip identification other flags, while it breaks the test because
windows set it to the same even it's not a fragment.

Normally it includes 2 typical ways to handle a TCP control flag,
'bypass' and 'finalize', 'bypass' means should be sent out directly,
while 'finalize' means the packets should also be bypassed, but this
should be done after search for the same connection packets in the
pool and drain all of them out, this is to avoid out of order fragment.

All the 'SYN' packets will be bypassed since this always begin a new'
connection, other flags such 'URG/FIN/RST/CWR/ECE' will trigger a
finalization, because this normally happens upon a connection is going
to be closed, an 'URG' packet also finalize current coalescing unit.

Statistics can be used to monitor the basic coalescing status, the
'out of order' and 'out of window' means how many retransmitting packets,
thus describe the performance intuitively.

Difference between ip v4 and v6 processing:
 Fragment length in ipv4 header includes itself, while it's not
 included for ipv6, thus means ipv6 can carry a real 65535 payload.

Note that main goal of implementing this feature in software
is to create reference setup for certification tests. In such
setups guest migration is not required, so the coalesced packets
not yet delivered to the guest will be lost in case of migration.

2d0ed5e642 xen: re-name XenDevice to XenLegacyDevice...
...and xen_backend.h to xen-legacy-backend.h

Rather than attempting to convert the existing backend infrastructure to
be QOM compliant (which would be hard to do in an incremental fashion),
subsequent patches will introduce a completely new framework for Xen PV
backends. Hence it is necessary to re-name parts of existing code to avoid
name clashes. The re-named 'legacy' infrastructure will be removed once all
backends have been ported to the new framework.

This patch is purely cosmetic. No functional change.

pvrdma setup requires vmxnet3 device on PCI function 0 and PVRDMA device
on PCI function 1.
pvrdma device needs to access vmxnet3 device object for several reasons:
1. Make sure PCI function 0 is vmxnet3.
2. To monitor vmxnet3 device state.
3. To configure node_guid accoring to vmxnet3 device's MAC address.

To be able to access vmxnet3 device the definition of VMXNET3State is
