Our aarch64 CI system uses 172.31.0.0/20. Because I was (and am)
lazy, my random_rfc1918_subnet() helper was only checking /24.
This causes flakes.
Solution is to actually do it right: binary arithmetic, prefix
matching. This is effectively impossible in bash, so, use a
hairy perl helper and add copious tests.

Problem: frequent CI flakes of the form:
Error: cannot listen on the TCP port: listen tcp4 :5355: bind: address already in use
Always 5355.
Cause: systemd-resolve listens on 5355, but not on 127.0.0.1. So
when GetPort() tries its is-it-in-use check by binding localhost,
it succeeds; but then podman binds * and fails.
Solution: GetPort(): test by binding 0.0.0.0.
Also, improve the failure message.

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.

Add Quadlet key and disconnect relationship withr read-only
Update and add tests
Update man with new key
Remove the reference to VolatileTmpfs in the man page to reduce its
usage, since the same functionality can be achieved using the Tmpfs key
while keeping its support to maintain backward compatibility

Docker deals with the --all flag on the client side while Podman does it
on the server side. Hence, make sure to not set the dangling filter
with two different values in the backend.

This change is the first step of integrating appendable string arrays
into containers.conf and starts with enabling the `Env`, `Mounts`, and
`Volumes` fields in the `[Containers]` table.
Both, Buildah and Podman, read (and sometimes write) the fields of the
`Config` struct at various places, so I decided to migrate the fields
step-by-step. The ones in this change are most critical ones for
customers. Once all string slices/arrays are migrated, the docs of
containers.conf will be updated. The current changes are entirely
transparent to users.

We only care about the version so just import the define package for it,
the main buildah package causes big transitive imports which fail to
build with the remote tag (i.e. libimage)

Tag now does a prepend internally instead of append with the names. Thus
the order changed which needs some test changes.

commit 7ade972102 introduced the change
that caused an issue in crun since it forces the root user session
instead of the system one when DBUS_SESSION_BUS_ADDRESS is set.
I am addressing it in crun, but for the time being, let's also not
pass the variable down to conmon since the assumption is that when
running as root the containers must be created on the system bus.

set the pod's hostname to the name of the machine/node as is
done in k8s. Also set the utsns to host.

Followup to #20394. For years (since BATS 1.5) we've been
seeing and ignoring nasty red warnings at the end of every
system test run. Thanks for fixing it, @giuseppe! But it
broke down in the '?' case when $expected_rc is empty:
test/system/helpers.bash: line 345: [: -eq: unary operator expected
Simple fix.

cp tests flake constantly under VFS (discovered in #20161),
and the way these tests were written makes it very, very hard
to understand failures.
This is a (sorry) hard-to-review cleanup:
- use distinctive container names, not just "cpcontainer"
- add distinctive test names (e.g. RUNNING vs CREATED)
- remove unnecessary code
- remove --pause=false (option is deprecated and, IIUC, a NOP)
- clean up some confusing slashes in paths
- "dot notation" tests:
- add a comment linking to issue, because that's a weird one
that makes no sense whatsoever
- fix tests, because they were actually not testing
This cleanup has been tested repeatedly in 20161, I'm just bringing
it into main because 20161's future is uncertain.
