403af209db s390x/pci: restore missing Query PCI Function CLP data
Some CLP response data was accidentally dropped when fixing endianness
issues with the Query PCI Function CLP response.  All of these values are
sent as 0s to the guest for emulated devices, so the impact is only
observed on passthrough devices.

24056cbfd5 hw/s390x: fix build for virtio-9p-ccw
Commit  2c44220d05 ("meson: convert hw/arch*"), which migrated the old
Makefile.objs to meson.build  accidentally excluded virtio-ccw-9p.c and
thus the virtio-9p-ccw device from the build (and potentially also
included the file virtio-ccw-blk.c twice in the source set). And since
CONFIG_VIRTFS can't be used the way it was used here (see commit
2c9dce0196 ("meson: do not use CONFIG_VIRTFS")), the preconditions have
to be written differently.

Let's fix this!

ea1b90b4fc target/s390x/arch_dump: Fix warning for the name field in the PT_NOTE section
There is a compiler warning with GCC 9.3 when compiling with
the -fsanitize=thread compiler flag:

 In function 'strncpy',
    inlined from 's390x_write_elf64_notes' at ../target/s390x/arch_dump.c:219:9:
 /usr/include/x86_64-linux-gnu/bits/string_fortified.h:106:10: error:
  '__builtin_strncpy' specified bound 8 equals destination size
  [-Werror=stringop-truncation]

Since the name should always be NUL-terminated, let's use g_strlcpy() to
silence this warning. And while we're at it, also add an assert() to make
sure that the provided names always fit the size field (which is fine for
the current callers, the function is called once with "CORE" and once with
"LINUX" as a name).

0110253e69 s390x/cpu_model: disallow unpack for --only-migratable
Secure execution (aka protected virtualization) guests cannot be
migrated at the moment. If the unpack facility is provided in the cpu
model, a guest may choose to transition to secure mode, making the
guest unmigratable at that point in time. If the machine was explicitly
started with --only-migratable, we would get a failure only when the
guest actually tries to transition; instead, explicitly disallow the
unpack facility if --only-migratable was specified to avoid late
surprises.

1d8d014e93 vhost: simplify vhost_dev_init() fail_busyloop label
Requiring a conditional for every goto is tedious:

  if (busyloop_timeout) {
      goto fail_busyloop;
  } else {
      goto fail;
  }

Move the conditional to into the fail_busyloop label so that it's safe
to jump to this label unconditionally.

This change makes the migrate_add_blocker() error case more consistent.
It jumped to fail_busyloop unconditionally whereas the memslots limits
error case was conditional.

b52fa0ea45 hw/pci: Have safer pcie_bus_realize() by checking error path
While pci_bus_realize() currently does not use the Error* argument,
it would be an error to leave pcie_bus_realize() setting bus->flags
if pci_bus_realize() had failed.

Fix by using a local Error* and return early (propagating the error)
if pci_bus_realize() failed.

fb59288239 virtio-net: handle zero mac for a vdpa peer
Some mlx vdpa devices with kernels at least up to 5.11 currently present
0 as their MAC address.  This is because they have not been
  pre-configured with a MAC: they have a learning bridge and only learn
the MAC once guest is up.  Kernel patches and tools to allow programming
the MAC from host are being developed. For now - since these
combinations exist in the field - let's detect zero mac and just try to
proceed with the mac from the qemu command line.

This makes the guest use this MAC to send packets in turn teaching
the MAC to the card, and things work.

TODO:
report the actual MAC from QEMU commad line in the info message.
TODO:
detect that a (non-zero) hardware MAC does not match QEMU command line
and fail init.

After fixing the _UID value for the primary PCI root bridge in

https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg08484.html

This change reverts the _UID update from 1 to 0 for q35 and i440fx
VMs before version 5.2 to maintain the original behaviour when
upgrading.

Right now, recoverable sense values are only passed directly to the
guest only for rerror=report.  However, when rerror/werror are 'stop'
we still don't want the host to be involved on every UNIT ATTENTION

6f1a5c37db virtio-scsi: don't process IO on fenced dataplane
If virtio_scsi_dataplane_start fails, there is a small window when it drops the
aio lock (in aio_wait_bh_oneshot) and the dataplane's AIO handler can
still run during that window.

This is done after the dataplane was marked as fenced, thus we use this flag
to avoid it doing any IO.

237377ac72 hvf: Sign the code after installation
Before this change, the code signed during the build was installed
directly.

However, the signature gets invalidated because meson modifies the code
to fix dynamic library install names during the install process.

It also prevents meson to strip the code because the pre-signed file is
not marked as an executable (although it is somehow able to perform the
modification described above).

With this change, the unsigned code will be installed and modified by
meson first, and a script signs it later.
