45b14be9b6 python: enable testing for 3.13
Python 3.13 is in beta and Fedora 41 is preparing to make it the default
system interpreter; enable testing for it.

(In the event problems develop prior to release, it should only impact
the check-python-tox job, which is not run by default and is allowed to
fail.)

06f3330bb0 tests/lcitool: Bump to latest libvirt-ci and update Fedora and Alpine version
Update to the latest version of lcitool. It dropped support for Fedora 38
and Alpine 3.18, so we have to update these to newer versions here, too.

Python 3.12 dropped the "imp" module which we still need for running
Avocado. Fortunately Fedora 40 still ships with a work-around package
that we can use until somebody updates our Avocado to a newer version.

641b1efe01 tests: Update our CI to use CentOS Stream 9 instead of 8
RHEL 9 (and thus also the derivatives) have been available since two
years now, so according to QEMU's support policy, we can drop the active
support for the previous major version 8 now.

Another reason for doing this is that Centos Stream 8 will go EOL soon:

https://blog.centos.org/2023/04/end-dates-are-coming-for-centos-stream-8-and-centos-linux-7/

  "After May 31, 2024, CentOS Stream 8 will be archived
   and no further updates will be provided."

Thus upgrade our CentOS Stream container to major version 9 now.

2355d18c79 tests/docker/dockerfiles: Run lcitool-refresh after the lcitool update
This update adds the removing of the EXTERNALLY-MANAGED marker files
that has been added to the lcitool recently.

Quoting Daniel:
"For those who don't know, python now commonly blocks the ability to
run 'pip install' outside of a venv. This generally makes sense for
a precious installation environment. Our containers are disposable
though, so a venv has no benefit. Removing the 'EXTERNALLY-MANAGED'
allows the historical arbitrary use of 'pip' outside a venv.
lcitool just does this unconditionally given the containers are
not precious."

cb039ef3d9 net: add initial support for AF_XDP network backend
AF_XDP is a network socket family that allows communication directly
with the network device driver in the kernel, bypassing most or all
of the kernel networking stack.  In the essence, the technology is
pretty similar to netmap.  But, unlike netmap, AF_XDP is Linux-native
and works with any network interfaces without driver modifications.
Unlike vhost-based backends (kernel, user, vdpa), AF_XDP doesn't
require access to character devices or unix sockets.  Only access to
the network interface itself is necessary.

This patch implements a network backend that communicates with the
kernel by creating an AF_XDP socket.  A chunk of userspace memory
is shared between QEMU and the host kernel.  4 ring buffers (Tx, Rx,
Fill and Completion) are placed in that memory along with a pool of
memory buffers for the packet data.  Data transmission is done by
allocating one of the buffers, copying packet data into it and
placing the pointer into Tx ring.  After transmission, device will
return the buffer via Completion ring.  On Rx, device will take
a buffer form a pre-populated Fill ring, write the packet data into
it and place the buffer into Rx ring.

AF_XDP network backend takes on the communication with the host
kernel and the network interface and forwards packets to/from the
peer device in QEMU.

Usage example:

  -device virtio-net-pci,netdev=guest1,mac=00:16:35:AF:AA:5C
  -netdev af-xdp,ifname=ens6f1np1,id=guest1,mode=native,queues=1

XDP program bridges the socket with a network interface.  It can be
attached to the interface in 2 different modes:

1. skb - this mode should work for any interface and doesn't require
         driver support.  With a caveat of lower performance.

2. native - this does require support from the driver and allows to
            bypass skb allocation in the kernel and potentially use
            zero-copy while getting packets in/out userspace.

By default, QEMU will try to use native mode and fall back to skb.
Mode can be forced via 'mode' option.  To force 'copy' even in native
mode, use 'force-copy=on' option.  This might be useful if there is
some issue with the driver.

Option 'queues=N' allows to specify how many device queues should
be open.  Note that all the queues that are not open are still
functional and can receive traffic, but it will not be delivered to
QEMU.  So, the number of device queues should generally match the
QEMU configuration, unless the device is shared with something
else and the traffic re-direction to appropriate queues is correctly
configured on a device level (e.g. with ethtool -N).
'start-queue=M' option can be used to specify from which queue id
QEMU should start configuring 'N' queues.  It might also be necessary
to use this option with certain NICs, e.g. MLX5 NICs.  See the docs
for examples.

In a general case QEMU will need CAP_NET_ADMIN and CAP_SYS_ADMIN
or CAP_BPF capabilities in order to load default XSK/XDP programs to
the network interface and configure BPF maps.  It is possible, however,
to run with no capabilities.  For that to work, an external process
with enough capabilities will need to pre-load default XSK program,
create AF_XDP sockets and pass their file descriptors to QEMU process
on startup via 'sock-fds' option.  Network backend will need to be
configured with 'inhibit=on' to avoid loading of the program.
QEMU will need 32 MB of locked memory (RLIMIT_MEMLOCK) per queue
or CAP_IPC_LOCK.

There are few performance challenges with the current network backends.

First is that they do not support IO threads.  This means that data
path is handled by the main thread in QEMU and may slow down other
work or may be slowed down by some other work.  This also means that
taking advantage of multi-queue is generally not possible today.

Another thing is that data path is going through the device emulation
code, which is not really optimized for performance.  The fastest
"frontend" device is virtio-net.  But it's not optimized for heavy
traffic either, because it expects such use-cases to be handled via
some implementation of vhost (user, kernel, vdpa).  In practice, we
have virtio notifications and rcu lock/unlock on a per-packet basis
and not very efficient accesses to the guest memory.  Communication
channels between backend and frontend devices do not allow passing
more than one packet at a time as well.

Some of these challenges can be avoided in the future by adding better
batching into device emulation or by implementing vhost-af-xdp variant.

There are also a few kernel limitations.  AF_XDP sockets do not
support any kinds of checksum or segmentation offloading.  Buffers
are limited to a page size (4K), i.e. MTU is limited.  Multi-buffer
support implementation for AF_XDP is in progress, but not ready yet.
Also, transmission in all non-zero-copy modes is synchronous, i.e.
done in a syscall.  That doesn't allow high packet rates on virtual
interfaces.

However, keeping in mind all of these challenges, current implementation
of the AF_XDP backend shows a decent performance while running on top
of a physical NIC with zero-copy support.

Test setup:

2 VMs running on 2 physical hosts connected via ConnectX6-Dx card.
Network backend is configured to open the NIC directly in native mode.
The driver supports zero-copy.  NIC is configured to use 1 queue.

Inside a VM - iperf3 for basic TCP performance testing and dpdk-testpmd
for PPS testing.

iperf3 result:
 TCP stream      : 19.1 Gbps

dpdk-testpmd (single queue, single CPU core, 64 B packets) results:
 Tx only         : 3.4 Mpps
 Rx only         : 2.0 Mpps
 L2 FWD Loopback : 1.5 Mpps

In skb mode the same setup shows much lower performance, similar to
the setup where pair of physical NICs is replaced with veth pair:

iperf3 result:
  TCP stream      : 9 Gbps

dpdk-testpmd (single queue, single CPU core, 64 B packets) results:
  Tx only         : 1.2 Mpps
  Rx only         : 1.0 Mpps
  L2 FWD Loopback : 0.7 Mpps

Results in skb mode or over the veth are close to results of a tap
backend with vhost=on and disabled segmentation offloading bridged
with a NIC.

2f7350cd43 gitlab: enable ccache for many build jobs
The `ccache` tool can be very effective at reducing compilation times
when re-running pipelines with only minor changes each time. For example
a fresh 'build-system-fedora' job will typically take 20 minutes on the
gitlab.com shared runners. With ccache this is reduced to as little as
6 minutes.

Normally meson would auto-detect existance of ccache in $PATH and use
it automatically, but the way we wrap meson from configure breaks this,
as we're passing in an config file with explicitly set compiler paths.
Thus we need to add $CCACHE_WRAPPERSPATH to the front of $PATH. For
unknown reasons if doing this in msys though, gcc becomes unable to
invoke 'cc1' when run from meson. For msys we thus set CC='ccache gcc'
before invoking 'configure' instead.

A second problem with msys is that cache misses are incredibly
expensive, so enabling ccache massively slows down the build when
the cache isn't well populated. This is suspected to be a result of
the cost of spawning processes under the msys architecture. To deal
with this we set CCACHE_DEPEND=1 which enables ccache's 'depend_only'
strategy. This avoids extra spawning of the pre-processor during
cache misses, with the downside that is it less likely ccache will
find a cache hit after semantically benign compiler flag changes.
This is the lesser of two evils, as otherwise we can't use ccache
at all under msys and remain inside the job time limit.

If people are finding ccache to hurt their pipelines, it can be
disabled by setting the 'CCACHE_DISABLE=1' env variable against
their gitlab fork CI settings.

a22a4b29ad tests/docker: add python3-venv dependency
Several debian-based tests need the python3-venv dependency as a
consequence of Debian debundling the "ensurepip" module normally
included with Python.

As mkvenv.py stands as of this commit, Debian requires EITHER:

(A) setuptools and pip, or
(B) ensurepip

mkvenv is a few seconds faster if you have setuptools and pip, so
developers should prefer the first requirement. For the purposes of CI,
the time-save is a wash; it's only a matter of who is responsible for
installing pip and when; the timing is about the same.

Arbitrarily, I chose adding ensurepip to the test configuration because
it is normally part of the Python stdlib, and always having it allows us
a more consistent cross-platform environment.

da9000784c tests/lcitool: Add mtools and xorriso and remove genisoimage as dependencies
Bios bits avocado tests need mformat (provided by the mtools package) and
xorriso tools in order to run within gitlab CI containers. Add those
dependencies within the Dockerfiles so that containers can be built with
those tools present and bios bits avocado tests can be run there.

xorriso package conflicts with genisoimage package on some distributions.
Therefore, it is not possible to have both the packages at the same time
in the container image uniformly for all distribution flavors. Further,
on some distributions like RHEL, both xorriso and genisoimage
packages provide /usr/bin/genisoimage and on some other distributions like
Fedora, only genisoimage package provides the same utility.
Therefore, this change removes the dependency on geninsoimage for building
container images altogether keeping only xorriso package. At the same time,
cdrom-test.c is updated to use and check for existence of only xorrisofs.
