RedMemSlotInfo keeps an array of groups, and each group contains an
array of slots. Unfortunately, these checks are off by 1, they check
that the index is greater or equal to the number of elements in the
array, while these arrays are 0 based. The check should only check for
strictly greater than the number of elements.
For the group array, this is not a big issue, as these memslot groups
are created by spice-server users (eg QEMU), and the group ids used to
index that array are also generated by the spice-server user, so it
should not be possible for the guest to set them to arbitrary values.
The slot id is more problematic, as it's calculated from a QXLPHYSICAL
address, and such addresses are usually set by the guest QXL driver, so
the guest can set these to arbitrary values, including malicious values,
which are probably easy to build from the guest PCI configuration.
This patch fixes the arrays bound check, and adds a test case for this.
This fixes CVE-2019-3813.

To set up a listening socket usually you call in sequence:
- socket;
- bind;
- listen.
If you try to bind() to a port when another socket is already
listening on that port, the bind() will fail.
However, it is possible that the bind() may succeed and the listen()
will fail, as demonstrated in the following sequence:
- socket() create socket 1;
- bind() to port N on socket 1;
- socket() create socket 2;
- bind() to port N on socket 2;
- listen() on socket 1;
- listen() on socket 2 <-- failure.
When running tests (especially multiple tests running in parallel), it
may sometimes happen that there are other tests already listening on
the port that we are trying to use. In this case, we want to ignore
this error and simply try to listen on a different port. We already
attempted to handle this scenario, but we were only ignoring bind()
errors and not listen() errors. So in the scenario mentioned above,
the listen() error was causing the entire test to fail instead of
allowing us to try to listen on another port.

In a comparison with current autotools build system, meson/ninja
provides a huge improvement in build speed, while keeping the same
functionalities currently available and being considered more user
friendly.
The new system coexists within the same repository with the current one,
so we can do more extensive testing of its functionality before deciding
if the old system can be removed, or for some reason, has to stay for
good.
- Meson: https://mesonbuild.com
This is the equivalent of autogen/configure step in autotools. It
generates the files that will be used by ninja to actually build the
source code.
The project has received lots of traction recently, with many GNOME
projects willing to move to this new build system. The following wiki
page has more details of the status of the many projects being ported:
https://wiki.gnome.org/Initiatives/GnomeGoals/MesonPorting
Meson has a python-like syntax, easy to read, and the documentation
on the project is very complete, with a dedicated page on how to port
from autotools, explaining how most common use cases can be
implemented using meson.
http://mesonbuild.com/Porting-from-autotools.html
Other important sources of information:
http://mesonbuild.com/howtox.htmlhttp://mesonbuild.com/Syntax.htmlhttp://mesonbuild.com/Reference-manual.html
- Ninja: https://ninja-build.org
Ninja is the equivalent of make in an autotools setup, which actually
builds the source code. It has being used by large and complex
projects such as Google Chrome, Android and LLVM. There is not much to
say about ninja (other than it is much faster than make) because we
won't interact directly with it as much, as meson does the middle man
job here. The reasoning for creating ninja in the first place is
explained on the following post:
http://neugierig.org/software/chromium/notes/2011/02/ninja.html
Also its manual provides more in-depth information about the design
principles:
https://ninja-build.org/manual.html
- Basic workflow:
Meson package is available for most if not all distros, so, taking
Fedora as an example, we only need to run:
# dnf -y install meson ninja-build.
With Meson, building in-tree is not possible at all, so we need to
pass a directory as argument to meson where we want the build to be
done. This has the advantage of creating builds with different options
under the same parent directory, e.g.:
$ meson ./build --prefix=/usr
$ meson ./build-extra -Dextra-checks=true -Dalignment-checks=true
After configuration is done, we call ninja to actually do the build.
$ ninja -C ./build
$ ninja -C ./build install
Ninja defaults to parallel builds, and this can be changed with the -j
flag.
$ ninja -j 10 -C ./build
- Hacking:
* meson.build: Mandatory for the project root and usually found under
each directory you want something to be built.
* meson_options.txt: Options that can interfere with the result of the
build.

The reason for this commit is that Meson expects all submodules to be

Due to the way Qemu handle the device, when an error occurs we must consume
all pending data inside the callback which reads data from the device.
If we don't flush this data, the next time spice-server tries to read from
the device (after the guest closes/reopens it), we'll be getting stale
data. This can happen because we cannot prevent the guest from writing to
the device even after it got in an error state.
This needs to be done within this callback, as QEMU returns 0 if you call
SpiceCharDeviceInterface::read() outside of it. QEMU invokes this callback
through a call to spice_server_char_device_wakeup.
On the test now we must test that we receive an error from the device.
Previously we checked that last part of the data was not read. Now
potentially all data are read, so we need another way to check the device
detected the error.

clang reports may warnings like:
test-display-base.c:252:11: error: cast from 'uint8_t *' (aka 'unsigned char *') to 'uint32_t *' (aka 'unsigned int *') increases required alignment from 1 to 4 [-Werror,-Wcast-align]
dst = (uint32_t *)bitmap;
^~~~~~~~~~~~~~~~~~
Use SPICE_ALIGNED_CAST/SPICE_UNALIGNED_CAST macros in common/mem.h to
mark the cast safe or possibly unsafe.
