It might be possible to avoid using SELinux template (%USERID),
and instead using regex to match user ids. This would allow
discarding the explicit restorecon call while during package builds[1].

Original suggestion from cathy.hu@suse.com:

> running restorecon would be unnecessary if the passt upstream selinux
> module would not use ${USERID} in pasta.fc (gets converted to [0-9]+ anyway)

Podman may also use directories under /tmp if XDG_RUNTIME_DIR is not
defined. Make sure the policy defined the right context for them as
well.

[sbrivio: minor style fixes]

Currently, pasta runs in the container_runtime_exec_t context when
running in a container. This is not ideal since it means that pasta runs
with more privileges than strictly necessary. This commit updates the
SELinux policy to have pasta transition to the pasta_t context when
started from the container_runtime_t context, adds the appropriate
labels to $XDG_RUNTIME_DIR/netns and
$XDG_RUNTIME_DIR/containers/networks/rootless-netns, and grants the
necessary permissions to the pasta_t context.

There's no reason to use wildcards, and we don't want any
similarly-named binary (not that I'm aware of any) to risk being
associated to passt_exec_t and pasta_exec_t by accident.

In practical terms, passt doesn't benefit from the additional
protection offered by the AGPL over the GPL, because it's not
suitable to be executed over a computer network.

Further, restricting the distribution under the version 3 of the GPL
wouldn't provide any practical advantage either, as long as the passt
codebase is concerned, and might cause unnecessary compatibility
dilemmas.
