Daniel P. Berrangé b9361bdc1f qemu-options: tweak to show that CPU count is optional

options are given, since it can be computed.

Hyman 927fae0eb9 tests/migration: fix unix socket migration
The test aborts and error message as the following be throwed:
"No such file or directory: '/var/tmp/qemu-migrate-{pid}.migrate",
when the unix socket migration test nearly done. The reason is
qemu removes the unix socket file after migration before
guestperf.py script do it. So pre-check if the socket file exists
when removing it to prevent the guestperf program from aborting.

See also commit f9cc00346d ("tests/migration: fix unix socket batch
migration").

Daniel P. Berrangé 2ce949a4c1 seccomp: don't block getters for resource control syscalls
Recent GLibC calls sched_getaffinity in code paths related to malloc and
when QEMU blocks access, it sends it off into a bad codepath resulting
in stack exhaustion[1]. The GLibC bug is being fixed[2], but none the
less, GLibC has valid reasons to want to use sched_getaffinity.

It is not unreasonable for code to want to run many resource syscalls
for information gathering, so it is a bit too harsh for QEMU to block
them.

Daniel P. Berrangé 260a13d472 crypto: flip priority of backends to prefer gcrypt
Originally we preferred to use nettle over gcrypt because
gnutls already links to nettle and thus it minimizes the
dependencies. In retrospect this was the wrong criteria to
optimize for.

Currently shipping versions of gcrypt have cipher impls that
are massively faster than those in nettle and this is way
more important.  The nettle library is also not capable of
enforcing FIPS compliance, since it considers that out of
scope. It merely aims to provide general purpose impls of
algorithms, and usage policy is left upto the layer above,
such as GNUTLS.

Daniel P. Berrangé 83bee4b51f crypto: replace 'des-rfb' cipher with 'des'
Currently the crypto layer exposes support for a 'des-rfb'
algorithm which is just normal single-DES, with the bits
in each key byte reversed. This special key munging is
required by the RFB protocol password authentication
mechanism.

Since the crypto layer is generic shared code, it makes
more sense to do the key byte munging in the VNC server
code, and expose normal single-DES support.

Replacing cipher 'des-rfb' by 'des' looks like an incompatible
interface change, but it doesn't matter.  While the QMP schema
allows any QCryptoCipherAlgorithm for the 'cipher-alg' field
in QCryptoBlockCreateOptionsLUKS, the code restricts what can
be used at runtime. Thus the only effect is a change in error
message.

Original behaviour:

 $ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G
 Formatting 'demo.luks', fmt=luks size=1073741824 key-secret=sec0 cipher-alg=des-rfb
 qemu-img: demo.luks: Algorithm 'des-rfb' not supported

New behaviour:

 $ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G
 Formatting 'demo.luks', fmt=luks size=1073741824 key-secret=sec0 cipher-alg=des-fish
 qemu-img: demo.luks: Invalid parameter 'des-rfb'

The built-in AES+XTS implementation is used for the LUKS encryption
When building system emulators it is reasonable to expect that an
external crypto library is being used instead. The performance of the
builtin XTS implementation is terrible as it has no CPU acceleration
support. It is thus not worth keeping a home grown XTS implementation
for the built-in cipher backend.

Daniel P. Berrangé f8157e100c crypto: add crypto tests for single block DES-ECB and DES-CBC
The GNUTLS crypto provider doesn't support DES-ECB, only DES-CBC.
We can use the latter to simulate the former, if we encrypt only
1 block (8 bytes) of data at a time, using an all-zeros IV. This
is a very inefficient way to use the QCryptoCipher APIs, but
since the VNC authentication challenge is only 16 bytes, this
is acceptable. No other part of QEMU should be using DES. This
test case demonstrates the equivalence of ECB and CBC for the
single-block case.

Cleber Rosa 414e9ae345 Acceptance tests: do not try to reuse packages from the system
The premise behind the original behavior is that it would save people
from downloading Avocado (and other dependencies) if already installed
on the system.  To be honest, I think it's extremely rare that the
same versions described as dependencies will be available on most
systems.  But, the biggest motivations here are that:

 1) Hacking on QEMU in the same system used to develop Avocado leads
    to confusion with regards to the exact bits that are being used;

 2) Not reusing Python packages from system wide installations gives
    extra assurance that the same behavior will be seen from tests run
    on different machines;

With regards to downloads, pip already caches the downloaded wheels
and tarballs under ~/.cache/pip, so there should not be more than
one download even if the venv is destroyed and recreated.

Wainer dos Santos Moschetta 6f651a6d84 python: Configure tox to skip missing interpreters
Currently tox tests against the installed interpreters, however if any
supported interpreter is absent then it will return fail. It seems not
reasonable to expect developers to have all supported interpreters
installed on their systems. Luckily tox can be configured to skip
missing interpreters.

This changed the tox setup so that missing interpreters are skipped by
default. On the CI, however, we still want to enforce it tests
against all supported. This way on CI the
--skip-missing-interpreters=false option is passed to tox.

Wainer dos Santos Moschetta 20bbf846b9 tests/acceptance: Automatic set -cpu to the test vm
This introduces a new feature to the functional tests: automatic setting of
the '-cpu VALUE' option to the created vm if the test is tagged with
'cpu:VALUE'. The 'cpu' property is made available to the test object as well.

For example, for a simple test as:

    def test(self):
        """
        🥑 tags=cpu:host
        """
        self.assertEqual(self.cpu, "host")
        self.vm.launch()

The resulting QEMU evocation will be like:

    qemu-system-x86_64 -display none -vga none \
        -chardev socket,id=mon,path=/var/tmp/avo_qemu_sock_pdgzbgd_/qemu-1135557-monitor.sock \

Cleber Rosa d5adf9d52b Acceptance Tests: support choosing specific distro and version
The tests based on the LinuxTest class give the test writer a ready to
use guest operating system, currently pinned to Fedora 31.

With this change, it's now possible to choose different distros and
versions, similar to how other tags and parameter can be set for the
target arch, accelerator, etc.

One of the reasons for this work, is that some development features
depend on updates on the guest side.  For instance the tests on
virtiofs_submounts.py, require newer kernels, and may benefit from
running, say on Fedora 34, without the need for a custom kernel.

Please notice that the pre-caching of the Fedora 31 images done during
the early stages of `make check-acceptance` (before the tests are
actually executed) are not expanded here to cover every new image
added.  But, the tests will download other needed images (and cache
them) during the first execution.
