The first was actually discovered during playing
around with a Windows 7 vServer. During resolution
change in Windows 7 it happens sometimes that Wind
currently a malicious client could define a payload
size of 2^32 - 1 bytes and send up to that size of
data to the vnc server. The server would allocated
that amount of memory which could easily create an
out of memory condition.
This patch limits the payload size to 1MB max.

this patch makes the VNC server work correctly if the
server surface and the guest surface have different sizes.
Basically the server surface is adjusted to not exceed VNC_MAX_WIDTH
x VNC_MAX_HEIGHT and additionally the width is rounded up to multiple of
VNC_DIRTY_PIXELS_PER_BIT.

Hi,
The commit 580b6b2aa2(dataplane: use the QEMU block layer for I/O)
introduces ~40% throughput regression on virtio-blk dataplane, and
one of causes is that submitting I/O at batch is removed.
This patchset trys to introduce this mechanism on block, at least,
linux-aio can benefit from that.
This patch introduces IO queue related APIs so that following
patches can support queuing I/O requests and submitting them
at batch for improving I/O performance.

This patch series introduces the image fuzzer, a tool for stability and
reliability testing.
Its approach is to run large amount of tests in background. During every test a
program (e.g. qemu-img) is called to read or modify an invalid test image.
A test image has valid inner structure defined by i

Layout submodule of qcow2 package creates a random valid image, randomly
selects some amount of its fields, fuzzes them and write the fuzzed image to
the file.
Now only header and header extensions are generated, remaining file is filled

The purpose of the test runner is to prepare test environment (e.g. create a
work directory, a test image, etc), execute the program under test with
parameters, indicate a test failure if the program was killed during test
execution and collect core dumps, logs and other test artifacts.

Fuzz submodule of qcow2 image generator contains fuzzing functions for image
fields.
Each fuzzing function contains list of constraints and call of a helper
function that randomly selects a fuzzed value satisfied to one of constraints.
For now constraints are only known as invalid or potentially da
