Instead of passing in defaults via WithStorageConfig after
computing them in cmd/podman/libpodruntime, do all defaults in
libpod itself.
This can alleviate ordering issues which caused settings in the
libpod config (most notably, volume path) to be ignored.

When removing volumes with rm --volumes we want to only remove
volumes that were created with the container. Volumes created
separately via 'podman volume create' should not be removed.
Also ensure that --rm implies volumes will be removed.

If this doesn't match, we end up not being able to access named
volumes mounted into containers, which is bad. Use the same
validation that we use for other critical paths to ensure this
one also matches.
Signed-off-by: Matthew Heon <matthew.heon@pm.me>
We want named volumes to be created in a subdirectory of the
c/storage graph root, the same as the libpod root directory is
now. As such, we need to adjust its location when the graph root
changes location.
Also, make a change to how we set the default. There's no need to
explicitly set it every time we initialize via an option - that
might conflict with WithStorageConfig setting it based on graph
root changes. Instead, just initialize it in the default config
like our other settings.

CRIU creates a log file during checkpointing in .../userdata/dump.log.
The problem with this file is, is that CRIU injects a parasite code into
the container processes and this parasite code also writes to the same
log file. At this point a process from the inside of the container is
trying to access the log file on the outside of the container and
SELinux prohibits this. To enable writing to the log file from the
injected parasite code, this commit creates an empty log file and labels
the log file with c.MountLabel(). CRIU uses existing files when writing
it logs so the log file label persists and now, with the correct label,
SELinux no longer blocks access to the log file.

We should just bind mount the original containers /etc/resolv.conf and /etchosts
into the new container. Changes in the resolv.conf and hosts should be seen
by all containers, This matches Docker behaviour.
In order to make this work the labels on these files need to have a shared
SELinux label.

The original intent behind the requirement was to ensure that, if
two SHM lock structs were open at the same time, we should not
make such a runtime available to the user, and should clean it up
instead.
It turns out that we don't even need to open a second SHM lock
struct - if we get an error mapping the first one due to a lock
count mismatch, we can just delete it, and it cleans itself up
when it errors. So there's no reason not to return a valid
runtime.
Signed-off-by: Matthew Heon <matthew.heon@pm.me>
When we're renumbering locks, we're destroying all existing
allocations anyways, so destroying the old lock struct is not a
particularly big deal. Existing long-lived libpod instances will
continue to use the old locks, but that will be solved in a
followon.
Also, solve an issue with returning error values in the C code.
There were a few places where we return ERRNO where it was not
set, so make them return actual error codes).
Signed-off-by: Matthew Heon <matthew.heon@pm.me>
We can't do renumbering after init - we need to open a
potentially invalid locks file (too many/too few locks), and then
potentially delete the old locks and make new ones.
We need to be in init to bypass the checks that would otherwise
make this impossible.
This leaves us with two choices: make RenumberLocks a separate
entrypoint from NewRuntime, duplicating a lot of configuration
load code (we need to know where the locks live, how many there
are, etc) - or modify NewRuntime to allow renumbering during it.
Previous experience says the first is not really a viable option
and produces massive code bloat, so the second it is.

I was looking into why we have locks in volumes, and I'm fairly
convinced they're unnecessary.
We don't have a state whose accesses we need to guard with locks
and syncs. The only real purpose for the lock was to prevent
concurrent removal of the same volume.
Looking at the code, concurrent removal ought to be fine with a
bit of reordering - one or the other might fail, but we will
successfully evict the volume from the state.
Also, remove the 'prune' bool from RemoveVolume. None of our
other API functions accept it, and it only served to toggle off
more verbose error messages.

Before, a container being run or started in a pod always restarted the infra container. This was because we didn't take running dependencies into account. Fix this by filtering for dependencies in the running state.
Signed-off-by: Peter Hunt <pehunt@redhat.com>
Prior, a pod would have to be started immediately when created, leading to confusion about what a pod state should be immediately after creation. The problem was podman run --pod ... would error out if the infra container wasn't started (as it is a dependency). Fix this by allowing for recursive start, where each of the container's dependencies are started prior to the new container. This is only applied to the case where a new container is attached to a pod.
Also rework container_api Start, StartAndAttach, and Init functions, as there was some duplicated code, which made addressing the problem easier to fix.
