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.

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.

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.

This patch checks that ioc is not null before
using it in tcp socket tcp_chr_add_watch function.
The failure occurs in replay mode of the execution,
when monitor and serial port are tcp servers,
and there are no clients connected to them:
-monitor tcp:127.0.0.1:8081,server,nowait
-serial tcp:127.0.0.1:8082,server,nowait

The command complete callback has a SCSIRequest as the first argument,
and the status field of that structure is identical to the 'status'
argument. So drop the argument from the callback.

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
(especially considered that the QMP event will not have enough information
to act on the report).

Instead of fishing it from *r->status, just pass the SCSI status
as a positive value of the second parameter and an errno as a
negative value.

The new function is an extension of the switch statement in scsi-disk.c
which also includes the errno cases only found in sg_io_sense_from_errno.
This allows us to consolidate the errno handling.

When requested to ignore errors, just do nothing and let the
request complete normally. This means that the request will
be accounted correctly.
This is what commit 40dce4ee61 ("scsi-disk: fix rerror/werror=ignore",
2018-10-19) was supposed to do:

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.

'enospc' is the default for -drive, but qemu allows user to set
drive option werror. If werror of scsi-generic is set to 'report'
by user, qemu will not allow vm to start.
This patch allow user to set werror as 'report' for scsi-generic.

The current code sets an infinite timeout on SG_IO requests,
causing the guest to stall if the host experiences a frame
loss.
This patch adds an 'io_timeout' parameter for SCSIDevice to
make the SG_IO timeout configurable, and also shortens the
default timeout to 30 seconds to avoid infinite stalls.
