hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35
Q35 has three different types of PCI devices hot-plug: PCIe Native,
SHPC Native and ACPI hot-plug. This patch changes the default choice
for cold-plugged bridges from PCIe Native to ACPI Hot-plug with
ability to use SHPC and PCIe Native for hot-plugged bridges.
This is a list of the PCIe Native hot-plug issues that led to this
change:
* no racy behavior during boot (see 110c477c2ed)
* no delay during deleting - after the actual power off software
must wait at least 1 second before indicating about it. This case
is quite important for users, it even has its own bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1594168
* no timer-based behavior - in addition to the previous example,
the attention button has a 5-second waiting period, during which
the operation can be canceled with a second press. While this
looks fine for manual button control, automation will result in
the need to queue or drop events, and the software receiving
events in all sort of unspecified combinations of attention/power
indicator states, which is racy and uppredictable.
* fixes:
* https://bugzilla.redhat.com/show_bug.cgi?id=1752465
* https://bugzilla.redhat.com/show_bug.cgi?id=1690256
To return to PCIe Native hot-plug:
-global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off
Known issue: older linux guests need the following flag
to allow hotplugged pci express devices to use io:
-device pcie-root-port,io-reserve=4096.
io is unusual for pci express so this seems minor.
We'll fix this by a follow up patch.

hw/pci/pcie: Do not set HPC flag if acpihp is used
Instead of changing the hot-plug type in _OSC register, do not
set the 'Hot-Plug Capable' flag. This way guest will choose ACPI
hot-plug if it is preferred and leave the option to use SHPC with
pcie-pci-bridge.
The ability to control hot-plug for each downstream port is retained,
while 'hotplug=off' on the port means all hot-plug types are disabled.

tests/docker: remove FEATURES env var from templates
In preparation for switching to auto-generated dockerfiles, remove the
FEATURES env variable. The equivalent functionality can be achieved in
most cases by just looking for existance of a binary.
The cases which don't correspond to binaries are simply dropped because
configure/meson will probe for any requested feature anyway.
It is good practice to use an explicit registry for referencing the base
image. This is because some distros will inject their own registries
into the search path. For example registry.fedoraproject.org comes ahead
of docker.io. Using an explicit registry avoids wasting time querying
multiple registries for images that they won't have.
tests/docker: use project specific container registries
Since Docker Hub has started to enforce pull rate limits on clients, it
is preferrable to use project specific container registries where they
are available. Fedora and OpenSUSE projects provide registries.
The images in these registries are also refreshed on a more regular
basis than the ones in docker hub, so the package update should
generally be faster.
While CentOS also has a registry it is considerably outdated compared
to docker.io, and also only provides x86 images, while docker.io images
are multi-arch.
Using BUILDKIT breaks with certain container registries such as CentOS,
with docker build reporting an error such as
failed to solve with frontend dockerfile.v0:
failed to build LLB: failed to load cache key:
unexpected status code

This adds support for running 4 jobs via Cirrus CI runners:
* FreeBSD 12
* FreeBSD 13
* macOS 11 with default XCode
* macOS 11 with latest XCode
The gitlab job uses a container published by the libvirt-ci
project (https://gitlab.com/libvirt/libvirt-ci) that contains
the 'cirrus-run' command. This accepts a short yaml file that
describes a single Cirrus CI job, runs it using the Cirrus CI
REST API, and reports any output to the console.
In this way Cirrus CI is effectively working as an indirect
custom runner for GitLab CI pipelines. The key benefit is that
Cirrus CI job results affect the GitLab CI pipeline result and
so the user only has look at one CI dashboard.

some limits are even modified by downstream distribtions. Thus it
is better to remove the specific limits entirely.

less, GLibC has valid reasons to want to use sched_getaffinity.

for information gathering, so it is a bit too harsh for QEMU to block
them.

io: use GDateTime for formatting timestamp for websock headers

often results in simpler code too.
Add an implementation of the QEMU cipher APIs to the gnutls
crypto backend. XTS support is only available for gnutls
version >= 3.6.8. Since ECB mode is not exposed by gnutls
APIs, we can't use the private XTS code for compatibility.
crypto: introduce build system for gnutls crypto backend
This introduces the build logic needed to decide whether we can
use gnutls as a crypto driver backend. The actual implementations
will be introduced in following patches. We only wish to use
gnutls if it has version 3.6.14 or newer, because that is what
finally brings HW accelerated AES-XTS mode for x86_64.
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.
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.
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.
The built-in DES implementation is used for the VNC server password
authentication scheme. When building system emulators it is reasonable
to expect that an external crypto library is being used. It is thus
not worth keeping a home grown DES implementation in tree.
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.

tests/acceptance/linux_ssh_mips_malta.py: drop identical setUp
These tests' setUp do not do anything beyong what their base class do.
And while they do decorate the setUp() we can decorate the classes
instead, so no functionality is lost here.
This is possible because since Avocado 76.0 we can decorate setUp()
directly.

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.
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.

tests/acceptance: Handle cpu tag on x86_cpu_model_versions tests
Some test cases on x86_cpu_model_versions.py are corner cases because they
need to pass extra options to the -cpu argument. Once the avocado_qemu
framework will set -cpu automatically, the value should be reset. This changed
those tests so to call set_vm_arg() to overwrite the -cpu value.
tests/acceptance: Add set_vm_arg() to the Test class
The set_vm_arg method is added to avocado_qemu.Test class on this
change. Use that method to set (or replace) an argument to the list of
arguments given to the QEMU binary.
