Some of the argument parsing in qemu-img uses strtoul() to parse
integer arguments. This is tricky to get correct and in fact the
code does not get it right, because it assigns the result of
strtoul() to an 'int' variable and then tries to check for > INT_MAX.
Coverity correctly complains that the comparison is always false.
Rewrite to use qemu_strtoul(), which has a saner convention for
reporting conversion failures.
(Fixes CID 1356421, CID 1356422, CID 1356423.)

Passing a request size larger than BDRV_REQUEST_MAX_BYTES to any of the
I/O commands results in an error. While 'read' and 'write' handle the
error correctly, 'aio_read' and 'aio_write' hit an assertion:
blk_aio_read_entry: Assertion `rwco->qiov->size == acb->bytes' failed.
The reason is that the QEMU I/O code cannot handle request sizes
larger than BDRV_REQUEST_MAX_BYTES, so this patch makes qemu-io check
that all values are within range.

The metadata overlap checks introduced in a40f1c2add help detect
corruption in the qcow2 image by verifying that data writes don't
overlap with existing metadata sections.
The 'refcount-block' check in particular iterates over the refcount
table in order to get the addresses of all refcount blocks and check
that none of them overlap with the region where we want to write.
The problem with the refcount table is that since it always occupies
complete clusters its size is usually very big. With the default
values of cluster_size=64KB and refcount_bits=16 this table holds 8192
entries, each one of them enough to map 2GB worth of host clusters.
So unless we're using images with several TB of allocated data this
table is going to be mostly empty, and iterating over it is a waste of
CPU. If the storage backend is fast enough this can have an effect on
I/O performance.
This patch keeps the index of the last used (i.e. non-zero) entry in
the refcount table and updates it every time the table changes. The
refcount-block overlap check then uses that index instead of reading
the whole table.
In my tests with a 4GB qcow2 file stored in RAM this doubles the
amount of write IOPS.

The result of openfile was not checked, leading to failure deep in the
actual command with confusing error message, and exiting with exit code 0.
Here is a simple example - trying to read with the wrong format:
$ touch file
$ qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
can't open device file: Image is not in qcow2 format
no file open, try 'help open'
0
With this patch, we fail earlier with exit code 1:
$ ./qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
can't open device file: Image is not in qcow2 format
1
Failing earlier, we don't log this error now:
no file open, try 'help open'
But some tests expected it; the line was removed from the test output.

commit 94d6a7a accidentally left the naming of runtime opts and QAPI
scheme inconsistent. As one consequence passing of parameters in the
URI is broken. Sync the naming of the runtime opts to the QAPI
scheme.
Please note that this is technically backwards incompatible with the 2.8
release, but the 2.8 release is the only version that had the wrong naming.
Furthermore release 2.8 suffered from a NULL pointer dereference during
URI parsing.

Current implementation invalidates firstly parent bds and then its
children. This leads to the following bug:
after incoming migration, in bdrv_invalidate_cache_all:
1. invalidate parent bds - reopen it with BDRV_O_INACTIVE cleared
2. child is not yet invalidated
3. parent check that its BDRV_O_INACTIVE is cleared
4. parent writes to child
5. assert in bdrv_co_pwritev, as BDRV_O_INACTIVE is set for child
This patch fixes it by just changing invalidate sequence: invalidate
children first.

In order to reduce the execution time, this patch optimize
the qmp_query_blockstats():
Remove the next_query_bds function.
Remove the bdrv_query_stats function.
Remove some judgement sentence.
The original qmp_query_blockstats calls next_query_bds to get
the next objects in each loops. In the next_query_bds, it checks
the query_nodes and blk. It also call bdrv_query_stats to get
the stats, In the bdrv_query_stats, it checks blk and bs each
times. This waste more times, which may stall the main loop a
bit. And if the disk is too many and donot use the dataplane
feature, this may affect the performance in main loop thread.
This patch removes that two functions, and makes the structure
clearly.

In bdrv_find_backing_image(), if we are searching an image for a backing
file that contains a protocol, we currently only compare unmodified
paths.
However, some management software will change the backing filename to be
a relative filename in a path. QEMU is able to handle this fine,
because internally it will use path_combine to put together the full
protocol URI.
However, this can lead to an inability to match an image during a QAPI
command that needs to use bdrv_find_backing_image() to find the image,
when it is searched by the full URI.
When searching for a protocol filename, if the straight comparison
fails, this patch will also compare against the full backing filename to
see if that is a match.

The problem was triggered by qemu-iotests case 055. It failed when it
was comparing the compressed vmdk image with original test.img.
The cause is that buf_len in vmdk_write_extent wasn't converted to
little-endian before it was stored to disk. But later vmdk_read_extent
read it and converted it from little-endian to cpu endian.
If the cpu is big-endian like s390, the problem will happen and
the data length read by vmdk_read_extent will become invalid!
The fix is to add the conversion in vmdk_write_extent, meanwhile,
repair the endianness problem of lba field which shall also be converted
to little-endian before storing to disk.

The 'check' program records timings for each test that
is run. These timings are only valid, however, for a
particular format/protocol combination. So if frequently
running 'check' with a variety of different formats or
protocols, the times printed can be very misleading.
Instead of having a single 'check.time' file, maintain
multiple 'check.time-$IMGPROTO-$IMGFMT' files.

is not part of the top image's backing chain, the user receives a rather
plain "Base not found" error message. This is not really helpful because
it does not explain what "not found" means, potentially leaving the user
wondering why qemu cannot find a file despite it clearly existing in the

Previous IGD, up through Broadwell, only seem to write GTT values into
the first 1MB of space allocated for the BDSM, but clearly the GTT
can be multiple MB in size. Our test in vfio_igd_quirk_data_write()
correctly filters out indexes beyond 1MB, but given the 1MB mask we're
using, we re-apply writes only to the first 1MB of the guest allocated
BDSM.
We can't assume either the host or guest BDSM is naturally aligned, so
we can't simply apply a different mask. Instead, save the host BDSM
and do the arithmetic to subtract the host value to get the BDSM
offset and add it to the guest allocated BDSM.

The AHCI emulation code supports 64-bit addressing and should advertise this
fact in the Host Capabilities register. Both Linux and Windows drivers test
this bit to decide if the upper 32 bits of various registers may be written
to, and at least some versions of Windows have a bug where DMA is attempted
with an address above 4GB but, in the absence of HOST_CAP_64, the upper 32
bits are left unititialized which leads to a memory corruption.

The blit_region_is_unsafe checks don't work correctly for the
patterncopy source. It's a fixed-sized region, which doesn't
depend on cirrus_blt_{width,height}. So go do the check in
cirrus_bitblt_common_patterncopy instead, then tell blit_is_unsafe that
it doesn't need to verify the source. Also handle the case where we
blit from cirrus_bitbuf correctly.
This patch replaces 5858dd1801883309bdd208d72ddb81c4e9fee30c.
Security impact: I think for the most part error on the safe side this
time, refusing blits which should have been allowed.
Only exception is placing the blit source at the end of the video ram,
so cirrus_blt_srcaddr + 256 goes beyond the end of video memory. But
even in that case I'm not fully sure this actually allows read access to
host memory. To trick the commit 5858dd18 security checks one has to
pick very small cirrus_blt_{width,height} values, which in turn implies
only a fraction of the blit source will actually be used.

When the guest sends VIRTIO_GPU_CMD_RESOURCE_UNREF without detaching the
backing storage beforehand (VIRTIO_GPU_CMD_RESOURCE_DETACH_BACKING)
we'll leak memory.
This patch fixes it for 3d mode, simliar to the 2d mode fix in commit
"b8e2392 virtio-gpu: call cleanup mapping function in resource destroy".

In virtio_gpu_set_scanout function, when creating the 'rect'
its refcount is set to 2, by pixman_image_create_bits and
qemu_create_displaysurface_pixman function. This can lead
a memory leak issues. This patch avoid this issue.

Peter Maydell recently ran into time-out problems with the
prom-env test on a rather slow ARM board. To tackle this issue,
we can speed up the test by running QEMU with "-nodefaults" for
the pseries machine, so that SLOF has less devices to scan during
boot, and by using the "nvramrc" environment variable instead of
"boot-command", since this variable is evaluated earlier in the
boot process.
And to be really sure that we do not face such time out problems
again, let's also increase the time out value from 100s to 120s
instead.

The Trusty based builds run a little slower than the main container
based ones. This is also true for the latest version of Clang. The
builds are getting very close (and occasionally run over) the 50 minute
timeout. Rather than partitioning by target I just split them into
linux-user and system builds.

This change allows the listen address and websocket address
options for -vnc to be repeated. This causes the VNC server
to listen on multiple addresses. e.g.
$ $QEMU -vnc vnc=localhost:1,vnc=unix:/tmp/vnc,\
websocket=127.0.0.1:8080,websocket=[::]:8081
results in listening on
127.0.0.1:5901, 127.0.0.1:8080, ::1:5901, :::8081 & /tmp/vnc

To iterate over all QemuOpts currently requires using a callback
function which is inconvenient for control flow. Add support for
using iterator functions more directly
QemuOptsIter iter;
QemuOpt *opt;
qemu_opts_iter_init(&iter, opts, "repeated-key");
while ((opt = qemu_opts_iter_next(&iter)) != NULL) {
....do something...
}

Remove the limitation that the VNC server can only listen on
a single resolved IP address. This uses the new DNS resolver
API to resolve a SocketAddress struct into an array of
SocketAddress structs containing raw IP addresses. The VNC
server will then attempt to listen on all resolved IP addresses.
The server must successfully listen on at least one of the
resolved IP addresses, otherwise an error will be reported.

The code which takes a SocketAddress and connects/listens on the
network is going to get more complicated to deal with multiple
listeners. Pull it out into a separate method to avoid making the
vnc_display_open method even more complex.

The code which interprets the CLI args to populate the SocketAddress
objects for plain & websockets VNC is quite complex already and will
need further enhancements shortly. Refactor it into separate methods
to avoid vnc_display_open getting even larger. As a side effect of
the refactoring, it is now possible to specify a listen address for
the websocket server explicitly. e.g,
-vnc localhost:5900,websockets=0.0.0.0:8080
will listen on localhost for the plain VNC server, but expose the
websockets VNC server on the public interface. This refactoring
also removes the restriction that prevents enabling websockets
when the plain VNC server is listening on a UNIX socket.
