This adds the QSPI0 controller to the SoC, and connects an ISSI
25WP256 flash to it. The generation of corresponding device tree
source fragment is also added.
Since the direct memory-mapped mode is not supported by the SiFive
SPI model, the <reg> property does not populate the second group
which represents the memory mapped address of the SPI flash.
With this commit, upstream U-Boot for the SiFive HiFive Unleashed
board can boot on QEMU 'sifive_u' out of the box. This allows users
to develop and test the recommended RISC-V boot flow with a real
world use case: ZSBL (in QEMU) loads U-Boot SPL from SPI flash to
L2LIM, then U-Boot SPL loads the payload from SPI flash that is
combined with OpenSBI fw_dynamic firmware and U-Boot proper.
Specify machine property `msel` to 6 to allow booting from the SPI
flash. U-Boot spl is directly loaded via `-bios`, and subsequent
payload is stored in the SPI flash image. Example command line:
$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -smp 5 -m 8G \
-bios u-boot-spl.bin -drive file=spi-nor.img,if=mtd

This adds the ISSI SPI flash support. The number of dummy cycles in
fast read, fast read dual output and fast read quad output commands
is currently using the default 8. Likewise, the same default value
is used for fast read dual/quad I/O command. Per the datasheet [1],
the number of dummy cycles is configurable, but this is not modeled
at present.
For flash whose size is larger than 16 MiB, the sequence of 3-byte
address along with EXTADD bit in the bank address register (BAR) is
not supported. We assume that guest software always uses op codes
with 4-byte address sequence. Fortunately, this is the case for both
U-Boot and Linux spi-nor drivers.
QPI (Quad Peripheral Interface) that supports 2-cycle instruction
has different default values for dummy cycles of fast read family
commands, and is unsupported at the time being.

virtiofs: drop remapped security.capability xattr as needed
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
On Linux, the 'security.capability' xattr holds a set of
capabilities that can change when an executable is run, giving
a limited form of privilege escalation to those programs that
the writer of the file deemed worthy.
Any write causes the 'security.capability' xattr to be dropped,
stopping anyone from gaining privilege by modifying a blessed
file.
Fuse relies on the daemon to do this dropping, and in turn the
daemon relies on the host kernel to drop the xattr for it. However,
with the addition of -o xattrmap, the xattr that the guest
stores its capabilities in is now not the same as the one that
the host kernel automatically clears.
Where the mapping changes 'security.capability', explicitly clear
the remapped name to preserve the same behaviour.
This bug is assigned CVE-2021-20263.

A pwrite() call returns the number of bytes written (or -1 on error),
and vfio-ccw compares this number with the size of the region to
determine if an error had occurred or not.
If they are not equal, this is a failure and the errno is used to
determine exactly how things failed. An errno of zero is possible
(though unlikely) in this situation and would be translated to a
successful operation.
If they ARE equal, the ret_code field is read from the region to
determine how to proceed. While the kernel sets the ret_code field
as necessary, the region and thus this field is not "written back"
to the user. So the value can only be what it was initialized to,
which is zero.
So, let's convert an unexpected length with errno of zero to a
return code of -EFAULT, and explicitly set an expected length to
a return code of zero. This will be a little safer and clearer.

The virtio standard specifies that any non-transitional device must
reject commands prior to revision setting (which we do). Devices
that are transitional need to assume revision 0 (legacy) if the
driver sends a non-revision-setting command first in order to
support legacy drivers. We neglected to do the latter.
Fortunately, nearly everything worked as intended anyway; the only
problem was not properly rejecting revision setting after some other
command had been issued. Easy to fix by setting revision to 0 if
we see a non-revision command on a legacy-capable revision-less
device.

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

ui/console used to accept NULL as graphic console surface, but its
semantics was inconsistent among displays:
- cocoa and gtk-egl perform NULL dereference.
- egl-headless, spice and spice-egl do nothing.
- gtk releases underlying resources.
- sdl2-2d and sdl2-gl destroys the window.
- vnc shows a message, "Display output is not active."
Fortunately, only virtio-gpu and virtio-gpu-3d assign NULL so
we can study them to figure out the desired behavior. They assign
NULL *except* for the primary display when the device is realized,
reset, or its scanout is disabled. This effectively destroys
windows for the (uninitialized) secondary displays.
To implement the consistent behavior of display device
realization/reset, this change embeds it to the operation
switching the surface. When NULL was given as a new surface when
switching, ui/console will instead passes a placeholder down
to each display listeners.
sdl destroys the window for a secondary console if its surface is a
placeholder. The other displays simply shows the placeholder.

This has the following visible changes:
- GBM is required only for OpenGL dma-buf.
- X11 is explicitly required by gtk-egl.
- EGL is now mandatory for the OpenGL displays.
The last one needs some detailed description. Before this change,
EGL was tested only for OpenGL dma-buf with the check of
EGL_MESA_image_dma_buf_export. However, all of the OpenGL
displays depend on EGL and EGL_MESA_image_dma_buf_export is always
defined by epoxy's EGL interface.
Therefore, it makes more sense to always check the presence of EGL
and say the OpenGL displays are available along with OpenGL dma-buf
if it is present.

A display can receive an image which its stride is greater than its

equals to the one of the whole image.

qemu_chr_be_write is called with len=1 for each character (SDL sends
more than once keystroke).
Modify gd_vc_in to call qemu_chr_be_write multiple times if necessary.

The detections of [NSView -enterFullScreen:] and
[NSView -exitFullScreen:] were wrong. A detection is coded as:
[NSView respondsToSelector:@selector(exitFullScreenModeWithOptions:)]
but it should be:
[NSView instancesRespondToSelector:@selector(exitFullScreenModeWithOptions:)]
Because of those APIs were not detected, ui/cocoa always falled
back to a borderless window whose frame matches the screen to
implement fullscreen behavior.
The code using [NSView -enterFullScreen:] and
[NSView -exitFullScreen:] will be used if you fix the detections,
but its behavior is undesirable; the full screen view stretches
the video, changing the aspect ratio, even if zooming is disabled.

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.

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.

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
af1b80ae it was discovered that this change updates Windows
configuration in an incompatible way causing network configuration
failure unless DHCP is used. More details provided on the list:
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.

Fixes: af1b80ae56 ("i386/acpi: fix inconsistent QEMU/OVMF device paths")
Options such as "-gdb" or "-serial" accept a part-QemuOpts part-parsed-by-hand
character device description. Do not use short form boolean options in the
QemuOpts part.

The functionality of -writeconfig is limited and the code
does not even try to detect cases where it prints incorrect
syntax (for example if values have a quote in them, since
qemu_config_parse does not support any kind of escaping)
so remove it.

Bus lock debug exception is a feature that can notify the kernel by
generate an #DB trap after the instruction acquires a bus lock when
CPL>0. This allows the kernel to enforce user application throttling or
mitigations.
This feature is enumerated via CPUID.(EAX=7,ECX=0).ECX[bit 24].
