The network list compat API requires us to include all containers with
their ip addresses for the selected networks. Because we have no network
-> container mapping in the db we have to go through all containers
every time. However the old code did it in the most ineffective way
possible, it quered the containers from the db for each individual
network. The of course is extremely expensive. Now the other expensive
call is calling Inspect() on the container each time. Inspect does for
more than we need.
To fix this we fist query containers only once for the API call, then
replace the inspect call with directly accessing the network status.
This will speed things up a lot!
The reported scenario includes 100 containers and 25 networks,
previously it took 1.5s for the API call not it takes 24ms, that is a
more than a 62x improvement. (tested with curl)

When we walk the /dev tree we need to lookup all device paths. Now in
order to get the major and minor version we have to actually stat each
device. This can again fail of course. There is at least a race between
the readdir at stat call so it must ignore ENOENT errors to avoid
the race condition as this is not a user problem. Second, we should
also not return other errors and just log them instead, returning an
error means stopping the walk and returning early which means inspect
fails with an error which would be bad.
Also there seems to be cases were ENOENT will be returned all the time,
e.g. when a device is forcefully removed. In the reported bug this is
triggered with iSCSI devices.
Because the caller does already lookup the device from the created map
it reports a warning there if the device is missing on the host so it
is not a problem to ignore a error during lookup here.
[NO NEW TESTS NEEDED] Requires special device setup to trigger
consistentlyand we cannot do that in CI.

Since wsl --version triggers help, which triggers an error code,
use that instead of text detection.

gvisor-tap-vsock is now a standalone package for Fedora 38 and higher so
we can simplify the rpm spec a lot by removing all subpackage
references.
If we need to bump podman on Fedora 37, that can be handled manually on
Fedora itself. The Packit config can be left unchanged. Any packit PRs created on
Fedora dist-git for Fedora 37 can simply be closed without merging.
Fedora 37 will go EOL soon so not much of a point to changing packit
config to exclude Fedora 37.

commit cf364703fc changed the way
/sys/fs/cgroup is mounted when there is not a netns and it now honors
the ro flag. The mount was created using a bind mount that is a
problem when using a cgroup namespace, fix that by mounting a fresh
cgroup file system.

The test started to fail in gating and on workstations. It turned out
that pushing the test image to the registry recompresses it which in
turn may change the digest. The digest now started to change; computing
it depends on the toolchain so the test passed before by pure luck it
seems.

this pr has the basic plumbing that allows the e2e machine tests to run
with the hyperv provider.
it requires a special fcos image right now because gvforwarder was not
in the upstream fcos images for hyperv.
changed the way "provider" is set; moved GetProvider functions to
pkg/machine/provider. provider is now set at the machine level.

Every few months we get a new CI failure that requires
scanning through logs that give no indication of what
is happening or where. Tracking down the error can
cost many hours.
Solution: pepper cirrus scripts with showrun(), which echoes
the command _and_ displays the source filename + lineno.
