2b9b83d9ce tests: Fix rsync of base rpmdb with sqlite
Apparently small rpmdb changes can cause the size to stay the
same due to preallocation, and rsync defaults to skipping files
based on (name, size, mtime).  It's really ostree's mtime canonicalization
that's unfortunate here.

Anyways, we obviously don't care about performance here so use
`-I` to disable that rsync check.

(Also remove the `mkdir -p` since it's not necessary since a long time)

e3978c924f Add testutils generate-synthetic-upgrade
We want to test upgrades that actually change files as a general
rule; in some cases we want to test "large" upgrades to validate
performance.

This code generates a "synthetic" upgrade that adds an ELF note
to a percentage of ELF files (randomly selected).  By doing
it this way we are only actually testing one version of the code.

Migrated from https://github.com/coreos/coreos-assembler/pull/1635/

412d025e06 tests: Make more resistant to releasever changes
Now that cosa and FCOS have moved to f32, a bunch of tests are breaking.

host to f32, and update the systemd example output.

c6e5e80d94 vmcheck: Work around read-only /sysroot
We need to adapt some of our tests here which assume that `/sysroot` is
writable. However, in FCOS this is no longer the case now that we enable
`sysroot.readonly`.

We only remount rw for the couple of operations that need it so that we
still retain coverage for the ro path everywhere else.

c7a9c3b1dd Rework vmcheck to use kola spawn, move off of PAPR
There's a lot going on here, but essentially:

1. We change the `vmcheck` model so that it always operates on an
   immutable base image. It takes that image and dynamically launches a
   separate VM for each test using `kola spawn`. This means we can drop
   a lot of hacks around re-using the same VMs.
2. Following from 1., `vmoverlay` now takes as input a base image,
   overlays the built rpm-ostree bits, then creates a new base image. Of
   course, we don't have to do this in CI, because we build FCOS with
   the freshly built RPMs (so it uses `SKIP_VMOVERLAY=1`). `vmoverlay`
   then will be more for the developer case where one doesn't want to
   iterate via `cosa build` to test rpm-ostree changes. I say "will"
   because the functionality doesn't exist yet; I'd like to enhance
   `cosa dev-overlay` to do this. (Note `vmsync` should still works just
   as before too.)
3. `vmcheck` can be run without building the tree first, as
   `tests/vmcheck.sh`. The `make vmcheck` target still exists though for
   finger compatibility and better meshing with `vmoverlay` in the
   developer case.

What's really nice about using kola spawn is that it takes care of a lot
of things for us, such as the qemu command, journal and console
gathering, and SSH.

Similarly to the compose testsuites, we're using parallel here to run
multiple vmcheck tests at once. (On developer laptops, we cap
parallelism at `$(nproc) - 1`).

571bd3a558 tests: Add hidden testutils subcommand
This is a hack to allow using `inject-pkglist` without having to build
the tree first.

Higher-level, I think we can split this back out again if we have a
`-tests` subpackage where we ship the vmcheck testsuite.

This bumps the requirement on the controlling host to Python 3 only.
It also bumps the requirement on the target host to Python 3 as well

c89f81c138 libvm: Use shared memory for SSH control socket instead of /var/tmp
In Fedora 29, and Fedora 30 Silverblue, I have come across the
following error when executing `make vmsync` from my build container
(also on Fedora 29 and Fedora 30 images respectively):

```
...
Failed to connect to new control master
...
Control socket connect(/var/tmp/ssh-vmcheck-1556768111752693879.sock): Connection refused
Failed to connect to new control master
...
```

Previously this worked with Fedora 28 as the host.

After changing the socket to be in /dev/shm, the SSH connection to
the `vmcheck` VM is successful and the sources sync over.

The cause of this seems to be a problem with overlayfs and unix
sockets: https://github.com/moby/moby/issues/12080

Since overlayfs is the default graph driver in Fedora now, work
around this by switching the socket to be in /dev/shm.

is "How serious and relevant are these advisories to me? How soon should
I reboot?". For the packages that I'm most familiar with, e.g. `kernel`
and `git-core`, I usually look up the advisory and check why it was
marked as a security update, mentioned CVEs, and how those affect me.

The updateinfo metadata includes a wealth of information that could be
useful here. In Fedora, CVEs treated by the security response team
result in RHBZs, which end up attached to the advisories and thus make
it into that metadata.

This patch tries to reduce friction in answering some of those questions
above by checking for those CVEs and printing a short description in the
output of `status -a`. Example:

f098d22e03 tests/vmcheck: Create correct base commits from layered
Our trick of using layered commits as base commit updates doesn't jive
well with the new opportunistic reuse of the base rpmdb. The issue is
that a layered commit includes the rpmdb of *its* base commit at the
`/usr/lib/sysimage` location. So to convert it into a proper base commit
means that the layered rpmdb should move there.

bfd39aecf3 status: Rework auto-update status display
First, split it into its own section; it's important enough to merit it.
Second, explicitly reference the systemd timer/service units.  For
example, a question I often have is "when is the next run" and of course
you can get that rpm `systemctl status rpm-ostreed-automatic.timer` but
you have to know that, and the reminder helps.

(I briefly looked at implementing the `Trigger` line from `systemctl status`
 but it's not entirely trivial...tempting to just fork off a `systemctl status | grep `)

`rpm-ostree upgrade` when auto-updates are enabled.

8387f1c7c3 Add "ex-stage" update policy, support for ostree staged deployments
Following up to https://github.com/projectatomic/rpm-ostree/pull/1352
AKA 506910d930

staging, let's add an `ex-stage` automatic update policy.

I chose to create a new `test-autoupdate-stage.sh` and rename
the previous one to `test-autoupdate-check.sh` in going with
the previous theme of smaller test files; it's
way faster to iterate on new tests when it's a new file. And adding
staging at the top would have been weird.

51fb641305 Initial support for automatic updates
This patch introduces a new `AutomaticUpdatePolicy` configuration. This
was a long time coming for rpm-ostree, given that its update model makes
it extremely apt for such a feature.

The config supports a `check` mode, which should be very useful to
Atomic Workstation users, as well as a `reboot` mode, which could be
used in its present form in simple single node Atomic Host situations.

There is still a lot of work to be done, including integrating
advisories, and supporting a `deploy` mode. This feature hopefully will
be leveraged as well by higher-level projects like GNOME Software and
Cockpit.

37273705dd app/db-diff: make use of new db API
This is the first step towards unifying how we introspect packages from
a specific commit. We currently do this in three ways: libdnf, librpm,
and now `rpmostree.rpmdb.pkglist`. I'd like to get to a point where we
only have `rpmostree.rpmdb.pkglist` and libdnf, the latter only when
more complex queries are required.

This patch teaches the `db diff` command to make use of the new db diff
API so that it can work even on metadata-only commits. This is relevant
for use cases mentioned in #558.

I didn't get rid of the `rpmhdrs_diff` functions right now because of
the `--changelogs` option: libdnf currently does not expose this, so we
fall back to the previous API in that case. OTOH, I wonder how much it's
actually used in the wild; maybe we could just nix it?

7056e6b726 daemon: Unify pkgcache with system repo
We originally needed the pkgcache to be a separate repo due to ostree's

in each pkg branch for different SELinux policies. In practice, there's
not much use in maintaining old copies and it's just easier to always
relabel on the fly. So then, the need for a separate repo completely
melts away.

This helps simplify the mental model a bit and allows us to avoid subtle
issues like #1047. Note however that the core is still capable of
handling split repos for the `--ex-unified-core` compose use case. Once
that and the jigdo work are a bit more settled, we can have a clearer
picture of how to simplify the core further.

The tricky bit is migrating the cache. When deploying, we check if a
pkgcache repo exists and migrate its refs if so. We then leave behind a
symlink to the system repo to remain compatible with older rpm-ostrees.

dc08ebda0e tests/libvm: use rsync and add yumrepo mode
I've been lazy about actually using using rsync instead of scp when
copying new RPMs over to the VM. We do this here. Also make
`vm_send_test_repo` take a mode argument that allows callers to
completely skip the sending of the repo file itself. This will be needed
for the `makecache` test, in which we *don't* want the repo to be local.
It looks cleaner anyway for the gpgcheck use case as well.

3f367dbce2 scripts+bwrap: Make script execution cancellable
Prep for implementing `rpm-ostree cancel`, but this works with the way we handle
`Ctrl-C` interactively on a client as well. Being able to cancel a script
execution is quite nice; some of them are expensive, and having one loop forever
has been known to happen.

a9c38d33b8 vmcheck: add SELinux labeling tests
There's a lot of paths in the core related to SELinux policy changes and
relabeling packages. We currently have no test coverage for them. We add
support in the test libraries here to build such packages.

We also add a test that checks both that we correctly relabel RPMs when
the policy changes and that we handle layered packages that install
SELinux packages properly.

cb7e84c4a6 libpriv/scripts: redirect scriptlet output to journal
Rather than just letting the scriptlets inherit the daemon's
stdout/stderr, redirect their outputs so that we can set a customized
identifier to make it easier to distinguish from the daemon output.

Also print out the `journalctl` command needed so that users can
investigate the output themselves.

2f6f8a910d libvm: set up ControlPath socket in /var/tmp
It turns out there's a much smaller limit than PATH_MAX for Unix
sockets. On Linux, it's 108 characters. It took me some time to figure
out why `vmcheck` would sometimes fail depending on where the src
directory is and how ${topsrcdir} is defined. Let's just make things
safer by just using /var/tmp.
