With the new rootless cni supporting network connect/disconnect is easy.
Combine common setps into extra functions to prevent code duplication.

Instead of creating an extra container create a network and mount
namespace inside the podman user namespace. This ns is used to
for rootless cni operations.
This helps to align the rootless and rootful network code path.
If we run as rootless we just have to set up a extra net ns and
initialize slirp4netns in it. The ocicni lib will be called in
that net ns.
This design allows allows easier maintenance, no extra container
with pause processes, support for rootless cni with --uidmap
and possibly more.
The biggest problem is backwards compatibility. I don't think
live migration can be possible. If the user reboots or restart
all cni containers everything should work as expected again.
The user is left with the rootless-cni-infa container and image
but this can safely be removed.
To make the existing cni configs work we need execute the cni plugins
in a extra mount namespace. This ensures that we can safely mount over
/run and /var which have to be writeable for the cni plugins without
removing access to these files by the main podman process. One caveat
is that we need to keep the netns files at `XDG_RUNTIME_DIR/netns`
accessible.
`XDG_RUNTIME_DIR/rootless-cni/{run,var}` will be mounted to `/{run,var}`.
To ensure that we keep the netns directory we bind mount this relative
to the new root location, e.g. XDG_RUNTIME_DIR/rootless-cni/run/user/1000/netns
before we mount the run directory. The run directory is mounted recursive,
this makes the netns directory at the same path accessible as before.
This also allows iptables-legacy to work because /run/xtables.lock is
now writeable.

Versions of the ps command have additional spaces between fields, this
manifests as the container asking to run "top" and API reporting "top "
as a process.
Endpoint and tests updated to check that "top" is reported.
There is no libpod specialized endpoint to update.

Issue #9573 (podman build --pull-never is a NOP) is fixed.
Remove the 'skip' in the buildah-bud pull-never test.
Signed-off-by: Ed Santiago <santiago@redhat.com>
The 'is' check was intended to be called with three arguments,
the last one being a nice helpful test name. There's a fallback
for two-argument calls, but it was a horrible FIXME.
New fallback: the most recently run podman command. We keep
track of it in each run_podman() invocation.
This is not ideal, because it's theoretically possible to
invoke 'is' on something other than the output of run_podman,
but this at least fixes the by-far-most-common case.

Add support for secretRef and secretKeyRef to allow env vars to be set
from a secret. As K8S secrets are dictionaries the secret value must
be a JSON dictionary compatible with the data field of a K8S secret
object. The keys must consist of alphanumeric characters, '-', '_'
or '.', and the values must be base64 encoded strings.
Signed-off-by: Alban Bedel <albeu@free.fr>
In K8S the pod creation fails if an env var reference a non existing
config map key. It can be marked as optional, but per default it is
mandatory. Podman on the other hand always treat such references as
optional.
Rework envVarsFrom() and envVarValue() to additionaly return an error
and add support for the optional attribute in configMapRef and
configMapKeyRef.

When kube play fails to create a volume, it should say which volume had
the problem so the user doesn't have to guess. For the following pod
spec:
apiVersion: v1
kind: Pod

containers:
- name: myfrontend

volumeMounts:
- mountPath: "/var/www/html"

podman will now report:

Currently pull policy is set incorrectly when users set --pull-never.
Also pull-policy is not being translated correctly when using

Fixes: #9573
Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
Since podman-remote resize requests can come in at random times, this
generates a real potential for race conditions. We should only be
attempting to resize TTY on running containers, but the containers can
go from running to stopped at any time, and returning an error to the
caller is just causing noice.
This change will basically ignore requests to resize terminals if the
container is not running and return the caller to success. All other
callers will still return failure.

If you are attempting to run a container in interactive mode, and want
a --tty, then there must be a terminal in use.
Docker exits right away when a user specifies to use a --interactive and
--TTY but the stdin is not a tty.
Currently podman will pull the image and then fail much later.
Podman will continue to run but will print an warning message.

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).

Erik Sjolund reported an issue where a badly formated file
could be passed into the `--tz` option and then the date in the container
would be badly messed up:
```
erik@laptop:~$ echo Hello > file.txt
erik@laptop:~$ podman run --tz=../../../home/erik/file.txt --rm -ti
docker.io/library/alpine cat /etc/localtime
Hello
erik@laptop:~$ podman --version
podman version 3.0.0-rc1
erik@laptop:~$
```
This fix checks to make sure the TZ passed in is a valid
value and then proceeds with the rest of the processing.
This was first reported as a potential security issue, but it
was thought not to be. However, I thought closing the hole
sooner rather than later would be good.

Set of scripts to run buildah's bud.bats test using
podman build in podman CI.
podman build is not 100% compatible with buildah bud.
In particular:
* podman defaults to --layers=true; buildah to false
* podman defaults to --force-rm=true; buildah to false
* podman error exit status is 125; buildah is 2
* differences in error messages, command-line arguments
Some of the above can be dealt with programmatically,
by tweaking the buildah helpers.bash (BATS helpers).
Some need to be tweaked by patching bud.bats itself.
This PR includes a patch that will, I fear, need to
be periodically maintained over time.
There will likely be failures when vendoring in a
new buildah, possibly because new tests were added
for new features that don't exist in podman, possibly
(I hope unlikely) if existing tests are changed in
ways that make the patch file fail to apply. I've
tried to write good instructions and to write the run
script in such a way that it will offer helpful hints
on failure. My instructions and code will be imperfect;
I hope they will be good enough to merit continued use
of this test (possibly with improvements to the instructions
as we learn more about real-world failures).
