The fedora minimal 39 image has been updated on the fedora registry and
removed the `useradd` binary. Since we were pulling by tag and not by
digest, updates to images outside of our control always entail a certain
risk - and now it bit us.
To fix it, try to move as many users of `useradd` to _our_ CITEST_IMAGE
and migrate the code where necessary to this Alpine-based tooling.
However, the Alpine-based `adduser` binary (not useradd!) doesn't work
well when being executed as a non-root user and will just error out.
Hence, move the fedora minimal image back to version 34 which is still
including the `useradd` binary.
Ultimately, all images on public registries should be pulled via digest
to make sure we pin them down. I refrain from doing this now to make
sure we can cherry-pick this PR to older branches and get things back
into a working state ASAP.

There is no reason to define the same code every time in each file, just
use global nodes. This diff should speak for itself.
CleanupSecrets()/Volume() no longer call Cleanup() directly, as the
global AfterEach node will always call Cleanup() this is no longer
necessary. If one AfterEach() node fails it will still run the others.
Also always unset the CONTAINERS_CONF env vars. This prevents people
from forgetting to unset it. And fix the special CONTAINERS_CONF logic
in the system connection tests, we do not want to preserve
CONTAINERS_CONF anyway so just remove this logic.
Ginkgo orders the BeforeEach and AfterEach nodes. They will be executed
from the outer-most defined to inner-most. This means our global
BeforeEach is always first. Only then the inner one (in the Describe()
function in each file). For AfterEach it is inverted, from the inner to
the outer.

Ginkgo v2 fixed this buffering the output and syncing the output so it

...at least as many as possible. "run/exec -it" make no sense
in a CI environment; I believe the vast majority of these are
the result of fingers typing on autopilot, then copy/pasting
cascades from those. This PR gets rid of as many -it/-ti as
possible. Some are still needed for testing purposes.
Y'all have no idea how much I hate #10927 (the "no logs from conmon"
flake). This does not fix the underlying problem, nor does it even
eliminate the flake (The "exec terminal doesn't hang" test needs
to keep the -ti flag, and that's one of the most popular flakers).
But this at least reduces the scope of the problem. It also removes
a ton of nasty orange "input device is not a TTY" warnings from logs.

Similar feature was added for named overlay volumes here: https://github.com/containers/podman/pull/12712
Following PR just mimics similar feature for anonymous volumes.
Often users want their anonymous overlayed volumes to be `non-volatile` in nature
that means that same `upper` dir can be re-used by one or more
containers but overall of nature of volumes still have to be overlay
so work done is still on a overlay not on the actual volume.
Following PR adds support for more advanced options i.e custom `workdir`
and `upperdir` for overlayed volumes. So that users can re-use `workdir`
and `upperdir` across new containers as well.
Usage
```console
podman run -it -v /some/path:/data:O,upperdir=/path/persistant/upper,workdir=/path/persistant/work alpine sh

The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

Many ginkgo tests have been written to use this evil form:

Expect(output to ContainSubstring("foo"))
...which yields:

e2e test failures are rife with messages like:
Expected 1 to equal 0
These make me cry. They're anti-helpful, requiring the reader
to dive into the source code to figure out what those numbers
mean.
Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I
don't know if it spits out a better diagnostic (I have no way
to run e2e tests on my laptop), but I have to fantasize that
it will, and given the state of our flakes I assume that at
least one test will fail and give me the opportunity to see
what the error message looks like.
THIS IS NOT REVIEWABLE CODE. There is no way for a human
to review it. Don't bother. Maybe look at a few random
ones for sanity. If you want to really review, here is
a reproducer of what I did:
cd test/e2e
! positive assertions. The second is the same as the first,
! with the addition of (unnecessary) parentheses because
! some invocations were written that way. The third is BeZero().
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go
! Same as above, but handles three non-numeric exit codes
! in run_exit_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
! negative assertions. Difference is the spelling of 'To(Not)',
! 'ToNot', and 'NotTo'. I assume those are all the same.
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
! negative, old use of BeZero()
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go
Run those on a clean copy of main branch (at the same branch
point as my PR, of course), then diff against a checked-out
copy of my PR. There should be no differences. Then all you
have to review is that my replacements above are sane.
UPDATE: nope, that's not enough, you also need to add gomega/gexec
to the files that don't have it:
perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}'))
UPDATE 2: hand-edit run_volume_test.go
UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places
UPDATE 4: skip a test due to bug #10935 (race condition)

Podman uses the volume option map to check if it has to mount the volume
or not when the container is started. Commit 28138dafcc added to uid
and gid options to this map, however when only uid/gid is set we cannot
mount this volume because there is no filesystem or device specified.
Make sure we do not try to mount the volume when only the uid/gid option
is set since this is a simple chown operation.
Also when a uid/gid is explicity set, do not chown the volume based on
the container user when the volume is used for the first time.

Fixes: #9573
Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
As part of a fix for an earlier bug (#5698) we added the ability
for Podman to chown volumes to correctly match the user running
in the container, even in adverse circumstances (where we don't
know the right UID/GID until very late in the process). However,
we only did this for volumes created automatically by a
`podman run` or `podman create`. Volumes made by
`podman volume create` do not get this chown, so their
permissions may not be correct. I've looked, and I don't think
there's a good reason not to do this chwon for all volumes the
first time the container is started.
I would prefer to do this as part of volume copy-up, but I don't
think that's really possible (copy-up happens earlier in the
process and we don't have a spec). There is a small chance, as
things stand, that a copy-up happens for one container and then
a chown for a second, unrelated container, but the odds of this
are astronomically small (we'd need a very close race between two
starting containers).

Instead of using the container's mountpoint as the base of the
chroot and indexing from there by the volume directory, instead
use the full path of what we want to copy as the base of the
chroot and copy everything in it. This resolves the bug, ends up
being a bit simpler code-wise (no string concatenation, as we
already have the full path calculated for other checks), and
seems more understandable than trying to resolve things on the
destination side of the copy-up.

This one is rather bizarre because it triggers only on some
systems. I've included a CI test, for example, but I'm 99% sure
we use images in CI that have volumes over empty directories, and
the earlier patch to change copy-up implementation passed CI
without complaint.
I can reproduce this on a stock F33 VM, but that's the only place
I have been able to see it.
Regardless, the issue: under certain as-yet-unidentified
environmental conditions, the copier.Get method will return an
ENOENT attempting to stream a directory that is empty. Work
around this by avoiding the copy altogether in this case.

The old copy-up implementation was very unhappy with symlinks,
which could cause containers to fail to start for unclear reasons
when a directory we wanted to copy-up contained one. Rewrite to
use the Buildah Copier, which is more recent and should be both
safer and less likely to blow up over links.
At the same time, fix a deadlock in copy-up for volumes requiring
mounting - the Mountpoint() function tried to take the
already-acquired volume lock.
