Ed Santiago d5f044ee7a System tests: reenable some skipped aarch64 tests
Background: in order to add aarch64 tests, we had to add
emergency skips to a lot of failing tests. No attempt was
ever made to understand why they were failing.

Fast forward to today, I filed #15888 just to see if tests
are still failing. Looks like a number of them are fixed.
(Yes, magically). Remove those skips.

See: #15074, #15277

Fix stutters
Podman adds an Error: to every error message.  So starting an error
message with "error" ends up being reported to the user as

Error: error ...

This patch removes the stutter.

Also ioutil.ReadFile errors report the Path, so wrapping the err message
with the path causes a stutter.

Ed Santiago 0a160fed77 Bump VMs, to Ubuntu 2204 with cgroups v1
...and enable the at-test-time confirmation, the one that
double-checks that if CI requests runc we actually use runc.
This exposed a nasty surprise in our setup: there are steps to
define $OCI_RUNTIME, but that's actually a total fakeout!
OCI_RUNTIME is used only in e2e tests, it has no effect
whatsoever on actual podman itself as invoked via command
line such as in system tests. Solution: use containers.conf

Given how fragile all this runtime stuff is, I've also added
new tests (e2e and system) that will check $CI_DESIRED_RUNTIME.

Image source: https://github.com/containers/automation_images/pull/146

Since we haven't actually been testing with runc, we need
to fix a few tests:

  - handle an error-message change (make it work in both crun and runc)
  - skip one system test, "survive service stop", that doesn't
    work with runc and I don't think we care.

...and skip a bunch, filing issues for each:

  - #15013 pod create --share-parent
  - #15014 timeout in dd
  - #15015 checkpoint tests time out under $CONTAINER
  - #15017 networking timeout with registry
  - #15018 restore --pod gripes about missing --pod
  - #15025 run --uidmap broken
  - #15027 pod inspect cgrouppath broken
  - ...and a bunch more ("podman pause") that probably don't
    even merit filing an issue.

Also, use /dev/urandom in one test (was: /dev/random) because
the test is timing out and /dev/urandom does not block. (But
the test is still timing out anyway, even with this change)

Also, as part of the VM switch we are now using go 1.18 (up
from 1.17) and this broke the gitlab tests. Thanks to @Luap99
for a quick fix.

Also, slight tweak to #15021: include the timeout value, and
reword message so command string is at end.

Also, fixed a misspelling in a test name.

Ed Santiago 0a202a9f03 system test image: bump to 20220615
Changes:
 - use --timestamp option to produce 'created' stamps
   that can be reliably tested in the image-history test

 - podman now supports manifest & multiarch run, so we
   no longer need buildah

 - bump up base alpine & busybox images

This turned out to be WAY more complicated than it should've been,
because:

 - alpine 3.14 fixed 'date -Iseconds' to include a colon in
   the TZ offset ("-07:00", was "-0700"). This is now consistent
   with GNU date's --iso-8601 format, yay, so we can eliminate
   a minor workaround.

 - with --timestamp, all ADDed files are set to that timestamp,
   including the custom-reference-timestamp file that many tests
   rely on. So we need to split the build into two steps. But:

 - ...with a two-step build I need to use --squash-all, not --squash, but:

 - ... (deep sigh) --squash-all doesn't work with --timestamp (#14536)
   so we need to alter existing tests to deal with new image layers.

 - And, long and sordid story relating to --rootfs. TL;DR that option
   only worked by a miracle relating to something special in one
   specific test image; it doesn't work with any other images. Fix
   seems to be complicated, so we're bypassing with a FIXME (#14505).

And, unrelated:

 - remove obsolete skip and workaround in run-basic test (dating
   back to varlink days)
 - add a pause-image cleanup to avoid icky red warnings in logs

Ed Santiago 97ee411465 system tests: add assert(), and start using it
Problem: the system test 'is()' checker was poorly thought out.
For example, there is no way to check for inequality or for
absence of a substring.

Solution, step 1: introduce new assert(), copied almost verbatim
from buildah, where it has been successful in addressing the
gaps in is().

The logical next step is to search the tests for 'die' and
for 'run', looking for negative assertions which we can
replace with assert(). There were a lot, and in the process
I found a number of ugly bugs in the tests themselves. I've
taken the liberty of fixing these.

Important note: at this time we have both assert() and is().
Replacing all instances of is() would be impossible to review.

David Gibson 0b5136c7ce Make error message matching in 030-run.bats less fragile
Amongst other things 030-run.bats checks for sensible error messages when
attempting a "podman run" with a non-existent or inaccessible path.  It
checks for these messages, which come from the low-level runtime, in a lot
of detail, including separate versions for runc and crun.  This is fragile
in several ways:
  * It's likely to fail if using a runtime other than crun or runc
  * It relies on detecting whether the runtime is crun vs. runc using the
    path, which could fail if the binary has been named something unusual
  * It will break if crun or runc ever alter their error message (even if
    it's just changing case)

This replaces the checked versions with a much more accepting regex which
will work for both the runc and crun messages, while still looking for the
essential pieces.  This isn't guaranteed to work with other runtimes, but
it's much more likely to.

support advanced network configuration via cli
Rework the --network parse logic to support multiple networks with
specific network configuration settings.
--network can now be set multiple times. For bridge network mode the
following options have been added:
  - **alias=name**: Add network-scoped alias for the container.
  - **ip=IPv4**: Specify a static ipv4 address for this container.
  - **ip=IPv6**: Specify a static ipv6 address for this container.
  - **mac=MAC**: Specify a static mac address address for this container.
  - **interface_name**: Specify a name for the created network interface inside the container.

So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99
for the default bridge network as well as for network names.
This is better than using --ip because we can set the ip per network
without any confusion which network the ip address should be assigned
to.
The --ip, --mac-address and --network-alias options are still supported
but --ip or --mac-address can only be set when only one network is set.
This limitation already existed previously.

The ability to specify a custom network interface name is new

Ed Santiago bf94ebf423 System tests: tighten 'is' operator
Fix day-one sloppiness: when I first wrote this framework
it compared strings using 'expr', not '=', to be more
forgiving of extra cruft in output. This was a bad decision.
It means that warnings or additional text are ignored:

    is "all is ok, NOT!"  "all is ok"  <-- this would pass

Solution: tighten up the 'is' check. Use '=' (direct
compare) first. If it fails, look for wild cards ('*')
or character classes ('[') in the expect string. If
so, and only then, use 'expr'. And, thanks to a clever
suggestion from Luap99, include '(using expr)' in the
error message when we do so; this could make it easier
for a developer to understand a string mismatch.

This change exposes a lot of instances in which we weren't
doing proper comparisons. Fix those. Thankfully, there
weren't as many as I'd feared.

Also, and completely unrelated, add '-T' flag to bats
helper, for showing timing results. (I will open this
as a separate PR if requested. I too find it offensive

Valentin Rothberg 0f7d54b026 migrate Podman to containers/common/libimage
Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.

Note that I tried to leave bread crumbs for changed tests.

Miscellaneous changes:

 * Some errors yield different messages which required to alter some
   tests.

 * I fixed some pre-existing issues in the code.  Others were marked as
   `//TODO`s to prevent the PR from exploding.

 * The `NamesHistory` of an image is returned as is from the storage.
   Previously, we did some filtering which I think is undesirable.
   Instead we should return the data as stored in the storage.

 * Touched handlers use the ABI interfaces where possible.

 * Local image resolution: previously Podman would match "foo" on
   "myfoo".  This behaviour has been changed and Podman will now
   only match on repository boundaries such that "foo" would match
   "my/foo" but not "myfoo".  I consider the old behaviour to be a
   bug, at the very least an exotic corner case.

 * Futhermore, "foo:none" does *not* resolve to a local image "foo"
   without tag anymore.  It's a hill I am (almost) willing to die on.

 * `image prune` prints the IDs of pruned images.  Previously, in some
   cases, the names were printed instead.  The API clearly states ID,
   so we should stick to it.

 * Compat endpoint image removal with _force_ deletes the entire not
   only the specified tag.

We also build a new :00000001 image, replacing :00000000,
because (sigh) some tests try to run 'true' in the container.
Include instructions on building said image.

Valentin Rothberg 2ec0e3b650 do not set empty $HOME
Make sure to not set an empty $HOME for containers and let it default to
"/".

Valentin Rothberg 821ef6486a fix logic when not creating a workdir
When resolving the workdir of a container, we may need to create unless
the user set it explicitly on the command line.  Otherwise, we just do a
presence check.  Unfortunately, there was a missing return that lead us
to fall through into attempting to create and chown the workdir.  That
caused a regression when running on a read-only root fs.

Ed Santiago 1c50e09b06 System test for #9096 (truncated stdout)
This actually tests conmon, not podman; but that's the whole
point of system tests in the first place: if a problem exists,
we want to fail loudly, no matter whose fault it is.

(I can't get this to fail on my f33 laptop; OP on #9096 claims
it only fails on Ubuntu. We'll see what happens in CI).

Valentin Rothberg 0f668aa085 workdir presence checks
A container's workdir can be specified via the CLI via `--workdir` and
via an image config with the CLI having precedence.

Since images have a tendency to specify workdirs without necessarily
shipping the paths with the root FS, make sure that Podman creates the
workdir.  When specified via the CLI, do not create the path, but check
for its existence and return a human-friendly error.

NOTE: `crun` is performing a similar check that would yield exit code
127.  With this change, however, Podman performs the check and yields
exit code 126.  Since this is specific to `crun`, I do not consider it
to be a breaking change of Podman.
