The NBD spec was recently clarified to state that a read of length 0
should not be attempted by a compliant client; but that a server must
still handle it correctly in an unspecified manner (that is, either
a successful no-op or an error reply, but not a crash) [1]. However,
it also implies that NBD_REPLY_TYPE_OFFSET_DATA must have a non-zero
payload length, but our existing code was replying with a chunk
that a picky client could reject as invalid because it was missing
a payload (our own client implementation was recently patched to be
that picky, after first fixing it to not send 0-length requests).
We are already doing successful no-ops for 0-length writes and for
non-structured reads; so for consistency, we want structured reply
reads to also be a no-op. The easiest way to do this is to return
a NBD_REPLY_TYPE_NONE chunk; this is best done via a new helper
function (especially since future patches for other structured
replies may benefit from using the same helper).

Ensure that the server is not sending unexpected chunk lengths
for either the NONE or the OFFSET_DATA chunk, nor unexpected
hole length for OFFSET_HOLE. This will flag any server as
broken that responds to a zero-length read with an OFFSET_DATA
(what our server currently does, but that's about to be fixed)
or with OFFSET_HOLE, even though we previously fixed our client
to never be able to send such a request over the wire.

The NBD spec was recently clarified to state that clients should
not send 0-length requests to the server, as the server behavior
is undefined [1]. We know that qemu-nbd's behavior is a successful
no-op (once it has filtered for read-only exports), but other NBD
implementations might return an error. To avoid any questionable
server implementations, it is better to just short-circuit such
requests on the client side (we are relying on the block layer to
already filter out requests such as invalid offset, write to a
read-only volume, and so forth); do the short-circuit as late as
possible to still benefit from protections from assertions that
the block layer is not violating our assumptions.

A closer read of the NBD spec shows that a structured reply chunk
for a hole is not quite identical to the prefix of a data chunk,
because the hole has to also send a 32-bit size field. Although
we do not yet send holes, we should fix the misleading information
in our header and make it easier for a future patch to support
sparse reads. Messed up in commit bae245d1.

The NBD spec says that clients should not try to write/trim to
an export advertised as read-only by the server. But we failed
to check that, and would allow the block layer to use NBD with
BDRV_O_RDWR even when the server is read-only, which meant we
were depending on the server sending a proper EPERM failure for
various commands, and also exposes a leaky abstraction: using
qemu-io in read-write mode would succeed on 'w -z 0 0' because
of local short-circuiting logic, but 'w 0 0' would send a
request over the wire (where it then depends on the server, and
fails at least for qemu-nbd but might pass for other NBD
implementations).
With this patch, a client MUST request read-only mode to access
a server that is doing a read-only export, or else it will get
a message like:
can't open device nbd://localhost:10809/foo: request for write access conflicts with read-only export
It is no longer possible to even attempt writes over the wire
(including the corner case of 0-length writes), because the block
layer enforces the explicit read-only request; this matches the
behavior of qcow2 when backed by a read-only POSIX file.
Fix several iotests to comply with the new behavior (since
qemu-nbd of an internal snapshot, as well as nbd-server-add over QMP,
default to a read-only export, we must tell blockdev-add/qemu-io to
set up a read-only client).

namelen should be here, length is unrelated, and always 0 at this
point. Broken in introduction in commit f37708f6, but mostly
harmless (replying with '' as the name does not violate protocol,
and does not confuse qemu as the nbd client since our implementation
does not ask for the name; but might confuse some other client that
does ask for the name especially if the default export is different
than the export name being queried).
Adding an assert makes it obvious that we are not skipping any bytes
in the client's message, as well as making it obvious that we were
using the wrong variable.

Commit b7a745d added a qemu_bh_cancel call to the completion function
as an optimization to prevent it from unnecessarily rescheduling itself.
This completion function is scheduled from worker_thread, after setting
the state of a ThreadPoolElement to THREAD_DONE.
This was considered to be safe, as the completion function restarts the
loop just after the call to qemu_bh_cancel. But, as this loop lacks a HW
memory barrier, the read of req->state may actually happen _before_ the
call, seeing it still as THREAD_QUEUED, and ending the completion
function without having processed a pending TPE linked at pool->head:
worker thread | I/O thread
------------------------------------------------------------------------
| speculatively read req->state
req->state = THREAD_DONE; |
qemu_bh_schedule(p->completion_bh) |
bh->scheduled = 1; |
| qemu_bh_cancel(p->completion_bh)
| bh->scheduled = 0;
| if (req->state == THREAD_DONE)
| // sees THREAD_QUEUED
The source of the misunderstanding was that qemu_bh_cancel is now being
used by the _consumer_ rather than the producer, and therefore now needs
to have acquire semantics just like e.g. aio_bh_poll.
In some situations, if there are no other independent requests in the
same aio context that could eventually trigger the scheduling of the
completion function, the omitted TPE and all operations pending on it
will get stuck forever.
[Added Sergio's updated wording about the HW memory barrier.

Test-crypto-hash calls qcrypto_hash_bytesv/digest/base64 with
errp=NULL, this will cause a NULL pointer dereference if afalg_driver
doesn't support requested algos:
ret = qcrypto_hash_afalg_driver.hash_bytesv(alg, iov, niov,
result, resultlen,
errp);
if (ret == 0) {
return ret;
}
error_free(*errp); // <--- here
Because the error message is thrown away immediately, we should
just pass NULL to hash_bytesv(). There is also the same problem in
afalg-backend cipher & hmac, let's fix them together.

Currently, to enable a pci device in the guest, the user has to issue
echo 1 > /sys/bus/pci/slots/00000000/power. This is not what people
expect. On an LPAR, the user can put a PCI device in configured or
deconfigured state via IOCDS. The "start in deconfigured state" can be
used for "sharing" a pci function across LPARs. This is not what we are
going to use in KVM, so always start configured.

When a base image locally defined by QEMU, such as in the debian images,
is updated, the dockerfile checksum mechanism in docker.py still skips
updating the derived image, because it only looks at the literal content
of the dockerfile, without considering changes to the base image.
For example we have a recent fix e58c1f9b35e81 that fixed
debian-win64-cross by updating its base image, debian8-mxe, but due to
above "feature" of docker.py the image in question is automatically NOT
rebuilt unless you add NOCACHE=1. It is noticed on Shippable:
https://app.shippable.com/github/qemu/qemu/runs/541/2/console
because after the fix is merged, the error still occurs, and the log
shows the container image is, as explained above, not updated.
This is because at the time docker.py was written, there wasn't any
dependencies between QEMU's docker images.
Now improve this to preprocess any "FROM qemu:*" directives in the
dockerfiles while doing checksum, and inline the base image's dockerfile
content, recursively. This ensures any changes on the depended _QEMU_
images are taken into account.
This means for external images that we expect to retrieve from docker
registries, we still do it as before. It is not perfect, because
registry images can get updated too. Technically we could substitute the
image name with its hex ID as obtained with $(docker images $IMAGE
--format="{{.Id}}"), but --format is not supported by RHEL 7, so leave
it for now.

Actual number of interrupt pins isn't known
in ppce500_init_mpic() so a hardcoded number
was used, which causes a crash with older openpic.
Instead, return the DeviceState* and change ppce500_init()
to call qdev_get_gpio_in() to get only the irq pins
which are needed.

While trying to make KVM PR usable again, commit 5dfaa532ae introduced a
regression: the current compat_pvr value is passed to KVM instead of the
new one. This means that we always pass 0 instead of the max-cpu-compat
PVR during the initial machine reset. And at CAS time, we either pass
the PVR from the command line or even don't call kvmppc_set_compat() at
all, ie, the PCR will not be set as expected.
For example if we start a big endian fedora26 guest in power7 compat
mode on a POWER8 host, we get this in the guest:
$ cat /proc/cpuinfo
processor : 0
cpu : POWER7 (architected), altivec supported
clock : 4024.000000MHz
revision : 2.0 (pvr 004d 0200)
timebase : 512000000
platform : pSeries
model : IBM pSeries (emulated by qemu)
machine : CHRP IBM pSeries (emulated by qemu)
MMU : Hash
but the guest can still execute POWER8 instructions, and the following
program succeeds:
int main()
{
asm("vncipher 0,0,0"); // ISA 2.07 instruction
}
Let's pass the new compat_pvr to kvmppc_set_compat() and the program fails
with SIGILL as expected.

If we iterate over the full port range without successfully binding+listening
on the socket, we'll try the next address, whereupon we overwrite the slisten
file descriptor variable without closing it.
Rather than having two places where we open + close socket FDs on different
iterations of nested for loops, re-arrange the code to always open+close
within the same loop iteration.

The ITS is not fully properly reset at the moment. Caches are
not emptied.
After a reset, in case we attempt to save the state before
the bound devices have registered their MSIs and after the
1st level table has been allocated by the ITS driver
(device BASER is valid), the first level entries are still
invalid. If the device cache is not empty (devices registered
before the reset), vgic_its_save_device_tables fails with -EINVAL.
This causes a QEMU abort().

The commit cddafd8f353d ("hw/intc/arm_gicv3_its: Implement state save
/restore") breaks the backward compatibility with the older kernels
where vITS save/restore support is not available. The vmstate function
vm_change_state_handler() should not be registered if the running kernel
doesn't support ITS save/restore feature. Otherwise VM instance will be
killed whenever vmstate callback function is invoked.
Observed a virtual machine shutdown with QEMU-2.10+linux-4.11 when testing
the reboot command "virsh reboot <domain> --mode acpi" instead of reboot.

For AArch32 LDREXD and STREXD, architecturally the 32-bit word at the
lowest address is always Rt and the one at addr+4 is Rt2, even if the
CPU is big-endian. Our implementation does these with a single
64-bit store, so if we're big-endian then we need to put the two
32-bit halves together in the opposite order to little-endian,
so that they end up in the right places. We were trying to do
this with the gen_aa32_frob64() function, but that is not correct
for the usermode emulator, because there there is a distinction
between "load a 64 bit value" (which does a BE 64-bit access
and doesn't need swapping) and "load two 32 bit values as one
64 bit access" (where we still need to do the swapping, like
system mode BE32).

On a successful address translation instruction, PAR is supposed to
contain cacheability and shareability attributes determined by the
translation. We previously returned 0 for these bits (in line with the
general strategy of ignoring caches and memory attributes), but some
guest OSes may depend on them.
This patch collects the attribute bits in the page-table walk, and
updates PAR with the correct attributes for all LPAE translations.
Short descriptor formats still return 0 for these bits, as in the
prior implementation.
