Some distros are now defaulting to LUKS version 2 which QEMU cannot
process. For our I/O test that validates interoperability between the
kernel/cryptsetup and QEMU, we need to explicitly ask for version 1
of the LUKS format.

Since byte strings are no longer the default in Python 3, we have to
explicitly use them where we need to, which is mostly when working with
structures. It also means that we need to open a file in binary mode
when we want to use structures.
On the other hand, we have to accomodate for the fact that some
functions (still) work with byte strings but we want to use unicode
strings (in Python 3 at least, and it does not matter in Python 2).
This includes base64 encoding, but it is most notable when working with
the subprocess module: Either we set universal_newlines to True so that
the default streams are opened in text mode (hence this parameter is
aliased as "text" as of 3.7), or, if that is not possible, we have to
decode the output to a normal string.

The test case uses block devices with driver=file, which causes the test

On some distros, whenever you close a block device file
descriptor there is a udev rule that resets the file
permissions. This can race with the test script when
we run qemu-io multiple times against the same block
device. Occasionally the second qemu-io invocation
will find udev has reset the permissions causing failure.

By default the PBKDF algorithm used with LUKS is tuned
based on the number of iterations to produce 1 second
of running time. This makes running the I/O test with
the LUKS format orders of magnitude slower than with
qcow2/raw formats.
When creating LUKS images, set the iteration time to
a 10ms to reduce the time overhead for LUKS, since
security does not matter in I/O tests.
Previously a full 'check -luks' would take
$ time ./check -luks
Passed all 22 tests
real 23m9.988s
user 21m46.223s
sys 0m22.841s
Now it takes
$ time ./check -luks
Passed all 22 tests
real 4m39.235s
user 3m29.590s
sys 0m24.234s
Still slow compared to qcow2/raw, but much improved
none the less.

When opening an existing LUKS volume, if the iv generator is
essiv, then the iv hash algorithm is mandatory to provide. We
must report an error if it is omitted in the cipher mode spec,
not silently default to hash 0 (md5). If the iv generator is
not essiv, then we explicitly ignore any iv hash algorithm,
rather than report an error, for compatibility with dm-crypt.
When creating a new LUKS volume, if the iv generator is essiv
and no iv hsah algorithm is provided, we should default to
using the sha256 hash.

It is important that the QEMU luks implementation retains 100%
compatibility with the reference implementation provided by
the combination of the linux kernel dm-crypt module and cryptsetup
userspace tools.
There is a matrix of tests to be performed with different sets
of encryption settings. For each matrix entry, two tests will
be performed. One will create a LUKS image with the cryptsetup
tool and then do I/O with both cryptsetup & qemu-io. The other
will create the image with qemu-img and then again do I/O with
both cryptsetup and qemu-io.
The new I/O test 149 performs interoperability testing between
QEMU and the reference implementation. Such testing inherantly
requires elevated privileges, so to this this the user must have
configured passwordless sudo access. The test will automatically
skip if sudo is not available.
The test has to be run explicitly thus:
cd tests/qemu-iotests
./check -luks 149
