247a80db45 test/system: remove distro-integration bats tag
The distro-integration tag was added for fedora openQA to only run a
subset of tests. However since it was added only a few new tests have
been labelled like that and in general a normal contributor or even
maintianer has no idea when to add this tag.

We also have been seeing several regressions getting into fedora that
these tests would have caught. As such I worked with Adam to enable all
tests for fedora openQA so we actually have proper coverage. This has
been working for a few weeks so I think we can dop these tags so
upstream does not need to bother with them at all.

514e686b4c podman events: show network create/remove event with journald
In the journald driver there is a bug where the network event
attributes are not preserved. This causes the network driver to be
missing and that in turn causes the ToHumanReadable() function to print
an empty line. Fix it by making sure we preserve the network driver in
the event attributes.

When podman restarts config values within the Engine are lost.
Add --hook-dirs arguments as appropriate to the cleanup command
so that hooks are preserved on restarts due to the on-restart setting

f87ab2b7a6 fix network DB desync after failed connect/disconnect
Networks are stored in two ways in the DB, first a static network list
which holds all the network with its option for the container. Second,
the network status which hold the actual network result from netavark
but only when the container is running.

If the container is running they must be in sync and podman inspect has
checks to ensure that as well it errors out of there is a desync between
the two.

As the adding to the db and doing actual networking configuration are
diffeent parts it possible that one worked while the other failed which
triggers the desync. To avoid this make the network connect/disconnect
code more robust against partial failures. When the network calls fail
we update the db again to remove/add the network back.

f8787bb219 test: use ncat over nc
nc can be provided by either ncat (nmap) or netcat (OpenBSD), we only
work with the nmap version so make sure we always use that one and not
the short alias which can be resolved to either one.

It is not clear to me what changed on rawhide but it seemsv netcat is
preferred even though we have nmap-ncat installed.

Note this only changes the host side nc calls, the Alpine based images
only have nc as command so we must continue to use it inside.

64516e1b8f test/system: add podman network reload test to distro gating
The recent fedora kernel 6.11.4 has a problem with ipv6 networks [1].
This is not a podman bug at all but rather a kernel regression. I can
reproduce the issue easily by running this test.

Given many users were hit by this add it to the distro level gating
which runs in the fedora openQA framework and then we should catch a
bad kernel like this hopefully in the future and prevent it from going
into stable.

77081df8cd libpod: bind ports before network setup
We bind ports to ensure there are no conflicts and we leak them into
conmon to keep them open. However we bound the ports after the network
was set up so it was possible for a second network setup to overwrite
the firewall configs of a previous container as it failed only later
when binding the port. As such we must ensure we bind before the network
is set up.

This is not so simple because we still have to take care of
PostConfigureNetNS bool in which case the network set up happens after
we launch conmon. Thus we end up with two different conditions.

Also it is possible that we "leak" the ports that are set on the
container until the garbage collector will close them. This is not
perfect but the alternative is adding special error handling on each
function exit after prepare until we start conmon which is a lot of work
to do correctly.

9945981afb test: remove publish tests from e2e
This test checks a simple publish which is already covered in many other
places, it also used iptables wich is a invalid assumption going forward
as we start to enable nftables as firewall driver.

The only thing these tests added where checking that we cannot resuse
the same port. Given there was more than one kernel regression[1,2]
about correctly failing with EADDRINUSE I also added the
distro-integration tag to make sure we catch this early in fedora
testing.

d27313ad10 systests: conditionalize slirp4netns tests

not be installed on a host (and, in gating tests, is not).
Deal with it.

Use podman itself, not 'which', to tell us if slirp4netns
is available. We don't want to duplicate podman's path-check
logic. Since this check is expensive, cache the result.

c0fb8fe594 CI: try to fix more networking flakes
There's a whole slew of networking-related flakes whose common
element seems to be improper use of curl. Fix those by:

  * add --retry --retry-connrefused; and/or
  * add -S ("show errors". Plain -s silences everything!); and/or
  * test exit status from curl; and/or
  * add wait_for_port after "podman run -d", to avoid races
  * log commands, to make debugging easier

Important note: wait_for_port() was not working with rootless
podman ports. Trivial proof:

  $ podman run -d --name foo -p 8192:80 \
      quay.io/libpod/testimage:20221018 \
      /bin/busybox-extras httpd -f -p 80
  $ grep :2000 /proc/net/tcp
  [no results]

Solution: use ss tool; it seems to handle this just fine.
There may be a better solution.

Oh, also, add -t1 to a podman restart, to shave 18s from test run.

bbd6281ecc libpod: restart+userns cleanup netns correctly
When a userns and netns is used we need to let the runtime create the
netns otherwise the netns is not owned by the right userns and thus
the capabilities would not be correct.

The current restart logic tries to reuse the netns which is fine if no
userns is used but when one is used we setup a new netns (which is
correct) but forgot to cleanup the old netns. This resulted in leaked
network namespaces and because no teardown was ever called leaked ipam
assignments, thus a quickly restarting container will run out of ip
space very fast.

c2575f726d sys tests: run_podman: check for unwanted warnings/errors
With few exceptions, commands that exit 0 should not emit any
messages with level=warning or =error. Let's start enforcing
that in run_podman.

Allow one-off exceptions, typically when we're testing an
actual warning condition (usual case: "podman stop" where it
times out to SIGKILL). Exceptions are specified via:

    run_podman 0+w subcommand...
               ^^^---- or, rarely, 0+e

"0" stands for "expect exit status 0", which is the default
so it's implicit anyway. The +w / +e (or even +we) is the
new part. I have added it to tests where necessary.

And, because life is what it is, add two global exceptions:

  - Debian. Because runc has too many flakes.
  - kube. Ditto. Kube commands emit lots of nasty error
    messages (yes, level=error) that don't seem to affect
    results.

all packages that can affect podman, so we don't go two
months with no bodhi builds then get caught by surprise
when systemd or kernel or crun change in ways that break us.

This PR introduces one bats tag, "distro-integration".
The intention is for OpenQA (or other) tests to install
the podman-tests package and run:

    bats --filter-tags distro-integration /usr/share/podman/test/system

Goal is to keep the test list short and sweet: we do not
need to test command-line option parsing. We *DO* need to
test interactions with systemd, kernel, nethack, and other
critical components.

1e94100940 Tests: remove/update obsolete skips
To silence my find-obsolete-skips script, remove the '#'
from the following issues in skip messages:

  #11784 #15013 #15025 #17433 #17436 #17456

Also update the messages to reflect the fact that the issues
will never be fixed.

Also remove ubuntu skips: we no longer test ubuntu.

Also remove one buildah skip that is no longer applicable:

Fixes: #17520

f1c68b79eb add hostname to network alias
We use the name as alias but using the hostname makes also sense and
this is what docker does. We have to keep the short id as well for
docker compat.

While adding some tests I removed some duplicated tests that were
executed twice for nv for no reason.

Fixes #17370

c33ba70f95 system tests: instrument, to try to catch unlinkat-ebusy
Several tweaks to see if we can track down #17216, the unlinkat-ebusy
flake:

 - teardown(): if a cleanup command fails, display it and its
   output to the debug channel. This should never happen, but
   it can and does (see #18180, dependent containers). We
   need to know about it.

 - selinux tests: use unique pod names. This should help when
   scanning journal logs.

 - many tests: add "-f -t0" to "pod rm"

And, several unrelated changes caught by accident:
 - images-commit-with-comment test: was leaving a stray image
   behind. Clean it up, and make a few more readability tweaks

 - podman-remote-group-add test: add an explicit skip()
   when not remote. (Otherwise, test passes cleanly on
   podman local, which is misleading)

 - lots of container cleanup and/or adding "--rm" to run commands,
   to avoid leaving stray containers

81e5bffc32 fix slirp4netns resolv.conf ip with a userns
When a userns is set we setup the network after the bind mounts, at the
point where resolv.conf is generated we do not yet know the subnet.
Just like the other dns servers for bridge networks we need to add the
ip later in completeNetworkSetup()

d85c8d7e84 system tests: use CONTAINERS_CONF_OVERRIDE
...not CONTAINERS_CONF. At least for most tests.

Nearly every system test currently using CONTAINERS_CONF=tmpfile
should be using CONTAINERS_CONF_OVERRIDE.

Simple reason: runtime (crun/runc), database_backend (bolt/sqlite),
logger, and other important settings from /etc/c.conf are not
usually written into the tmpfile. Those tests, therefore, are
not running podman as configured on the system.

Much more discussion: #15413

This PR is a prerequisite for enabling sqlite system tests. For
the sake of simplicity and sanity, I choose to submit the sqlite
switch as a separate PR once this passes and merges.
