722f1352b6 hw/riscv: sifive_u: Add QSPI2 controller and connect an SD card
This adds the QSPI2 controller to the SoC, and connects an SD
card to it. The generation of corresponding device tree source
fragment is also added.

Specify machine property `msel` to 11 to boot the same upstream
U-Boot SPL and payload image for the SiFive HiFive Unleashed board.
Note subsequent payload is stored in the SD card image.

$ qemu-system-riscv64 -nographic -M sifive_u,msel=11 -smp 5 -m 8G \

145b299139 hw/riscv: sifive_u: Add QSPI0 controller and connect a flash
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

10509e1095 hw/block: m25p80: Add ISSI SPI flash support
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.

e586edcb41 virtiofs: drop remapped security.capability xattr as needed
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.

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
af1b80ae it was discovered that this change updates Windows

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

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.

efce01bcb6 configure: fix --enable-fuzzing linker failures
With --enable-fuzzing, QEMU_CFLAGS include -fsanitize=fuzzer-no-link.
This should allow us to build non-fuzzer binaries using objects
instrumented for fuzzing. However, to do that, we also need to link with
-fsanitize=fuzzer-no-link. We were not doing that.

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.

93a1100768 docs: move CODING_STYLE into the developer documentation
There is no particular reason to keep this on it's own in the root of
the tree. Move it into the rest of the fine developer manual and fixup
any links to it. The only tweak I've made is to fix the code-block
annotations to mention the language C.
