vfio: Fix null pointer dereference bug in vfio_bars_finalize()
vfio_realize() has the following flow:
1. vfio_bars_prepare() -- sets VFIOBAR->size.
2. msix_early_setup().
3. vfio_bars_register() -- allocates VFIOBAR->mr.
After vfio_bars_prepare() is called msix_early_setup() can fail. If it
does fail, vfio_bars_register() is never called and VFIOBAR->mr is not
allocated.
In this case, vfio_bars_finalize() is called as part of the error flow
to free the bars' resources. However, vfio_bars_finalize() calls
object_unparent() for VFIOBAR->mr after checking only VFIOBAR->size, and
thus we get a null pointer dereference.
Fix it by checking VFIOBAR->mr in vfio_bars_finalize().

vfio/migration: Free resources when vfio_migration_realize fails
When vfio_realize() succeeds, hot unplug will call vfio_exitfn()
to free resources allocated in vfio_realize(); when vfio_realize()
fails, vfio_exitfn() is never called and we need to free resources
in vfio_realize().
In the case that vfio_migration_realize() fails,
e.g: with -only-migratable & enable-migration=off, we see below:
(qemu) device_add vfio-pci,host=81:11.1,id=vfio1,bus=root1,enable-migration=off
0000:81:11.1: Migration disabled
Error: disallowing migration blocker (--only-migratable) for: 0000:81:11.1: Migration is disabled for VFIO device
If we hotplug again we should see same log as above, but we see:
(qemu) device_add vfio-pci,host=81:11.1,id=vfio1,bus=root1,enable-migration=off
Error: vfio 0000:81:11.1: device is already attached
That's because some references to VFIO device isn't released.
For resources allocated in vfio_migration_realize(), free them by
jumping to out_deinit path with calling a new function
vfio_migration_deinit(). For resources allocated in vfio_realize(),
free them by jumping to de-register path in vfio_realize().

vfio/migration: Change vIOMMU blocker from global to per device
Contrary to multiple device blocker which needs to consider already-attached
devices to unblock/block dynamically, the vIOMMU migration blocker is a device
specific config. Meaning it only needs to know whether the device is bypassing
or not the vIOMMU (via machine property, or per pxb-pcie::bypass_iommu), and
does not need the state of currently present devices. For this reason, the
vIOMMU global migration blocker can be consolidated into the per-device
migration blocker, allowing us to remove some unnecessary code.
This change also makes vfio_mig_active() more accurate as it doesn't check for
global blocker.

linux-user: Fix accept4(SOCK_NONBLOCK) syscall
The Linux accept4() syscall allows two flags only: SOCK_NONBLOCK and
SOCK_CLOEXEC, and returns -EINVAL if any other bits have been set.
Change the qemu implementation accordingly, which means we can not use
the fcntl_flags_tbl[] translation table which allows too many other
values.
Beside the correction in behaviour, this actually fixes the accept4()
emulation for hppa, mips and alpha targets for which SOCK_NONBLOCK is
different than TARGET_SOCK_NONBLOCK (aka O_NONBLOCK).
The fix can be verified with the testcase of the debian lwt package,
which hangs forever in a read() syscall without this patch.

linux-user: Fix fcntl() and fcntl64() to return O_LARGEFILE for 32-bit targets
When running a 32-bit guest on a 64-bit host, fcntl[64](F_GETFL) should
return with the TARGET_O_LARGEFILE flag set, because all 64-bit hosts
support large files unconditionally.
But on 64-bit hosts, O_LARGEFILE has the value 0, so the flag
translation can't be done with the fcntl_flags_tbl[]. Instead add the
TARGET_O_LARGEFILE flag afterwards.
Note that for 64-bit guests the compiler will optimize away this code,
since TARGET_O_LARGEFILE is zero.

qemu_cleanup: begin drained section after vm_shutdown()
in order to avoid requests being stuck in a BlockBackend's request
queue during cleanup. Having such requests can lead to a deadlock [0]
with a virtio-scsi-pci device using iothread that's busy with IO when
initiating a shutdown with QMP 'quit'.
There is a race where such a queued request can continue sometime
(maybe after bdrv_child_free()?) during bdrv_root_unref_child() [1].
The completion will hold the AioContext lock and wait for the BQL
during SCSI completion, but the main thread will hold the BQL and
wait for the AioContext as part of bdrv_root_unref_child(), leading to
the deadlock [0].

Bump the mypy and wrapt versions to fix this, while remaining

ppc/pnv: Add QME region for P10
The Quad Management Engine (QME) manages power related settings for its
quad. The xscom region is separate from the quad xscoms, therefore a new
region is added. The xscoms in a QME select a given core by selecting
the forth nibble.
Implement dummy reads for the stop state history (SSH) and special
wakeup (SPWU) registers. This quietens some sxcom errors when skiboot
boots on p10.
Power9 does not have a QME.

igb: Remove obsolete workaround for Windows
I confirmed it works with Windows even without this workaround. It is
likely to be a mistake so remove it.

e1000e: Add ICR clearing by corresponding IMS bit
The datasheet does not say what happens when interrupt was asserted
(ICR.INT_ASSERT=1) and auto mask is *not* active.
However, section of 13.3.27 the PCIe* GbE Controllers Open Source
Software Developer’s Manual, which were written for older devices,
namely 631xESB/632xESB,
82563EB/
82564EB,
82571EB/82572EI &
82573E/82573V/82573L, does say:
> If IMS = 0b, then the ICR register is always clear-on-read. If IMS is
> not 0b, but some ICR bit is set where the corresponding IMS bit is not
> set, then a read does not clear the ICR register. For example, if
> IMS =
10101010b and ICR =
01010101b, then a read to the ICR register
> does not clear it. If IMS =
10101010b and ICR =
0101011b, then a read
> to the ICR register clears it entirely (ICR.INT_ASSERTED = 1b).
Linux does no longer activate auto mask since commit
0a8047ac68e50e4ccbadcfc6b6b070805b976885 and the real hardware clears
ICR even in such a case so we also should do so.

Move the file descriptor type checking before doing anything with it.
If it's not usable, don't close it as it could be in use by another

virtio-net: correctly report maximum tx_queue_size value
Maximum value for tx_queue_size depends on the backend type.
1024 for vDPA/vhost-user, 256 for all the others.
The value is returned by virtio_net_max_tx_queue_size() to set the
parameter:
n->net_conf.tx_queue_size = MIN(virtio_net_max_tx_queue_size(n),
n->net_conf.tx_queue_size);
But the parameter checking uses VIRTQUEUE_MAX_SIZE (1024).
So the parameter is silently ignored and ethtool reports a different
value than the one provided by the user.
... -netdev tap,... -device virtio-net,tx_queue_size=1024
# ethtool -g enp0s2
Ring parameters for enp0s2:
Pre-set maximums:
RX: 256
RX Mini: n/a
RX Jumbo: n/a
TX: 256
Current hardware settings:
RX: 256
RX Mini: n/a
RX Jumbo: n/a
TX: 256
... -netdev vhost-user,... -device virtio-net,tx_queue_size=2048
Invalid tx_queue_size (= 2048), must be a power of 2 between 256 and 1024
With this patch the correct maximum value is checked and displayed.
For vDPA/vhost-user:
Invalid tx_queue_size (= 2048), must be a power of 2 between 256 and 1024
For all the others:
Invalid tx_queue_size (= 512), must be a power of 2 between 256 and 256
