While we do protect against path traversal during pull, let's also validate
during checkout; it's a cheap operation and provides good last-mile protection.

I was reading about a recent security issue with both EMC and VMWare:
https://arstechnica.com/information-technology/2018/01/emc-vmware-security-bugs-throw-gasoline-on-cloud-security-fire/
It's a classic path traversal problem, and that made me think more about our
handling of this in libostree. Fortunately of course, not being new to
this rodeo, long ago I *did* consider path traversal. Inside the pull
code, we call `ot_util_filename_validate()`. Also, `fsck` does this too.
I have further followups here, but let's add some test cases for this. I crafted
a repository with a `../` in a dirtree object by patching libostree to inject
it, and that's included as a tarball.
This patch covers the two cases where we do already have checks; pulling
via HTTP, and in `fsck`.

All the current uses of the find-remotes command in the tests use it to
find configured remotes or mounted (USB) remotes, so using
--finders=config and --finders=mount in the tests respectively shouldn't
affect the correctness of the tests. It does however allow the tests to
be run in an environment that doesn't have an Avahi daemon.

Previously when initramfs-* was not found in a deployment's
boot directory, it was assumed that rootfs is prepared for
ostree booting by a kernel patch.
With this patch, the behaviour changes to be - if initramfs-*
is not found, assume that system is using a static
ostree-prepare-root as init process. Booting without initramfs
is a common use case on embedded systems. This approach is
also more convenient, than having to patch the kernel.

Clients of libostree such as rpm-ostree make extensive use of the
`ostree commit -b foo --tree=ref=foo` pattern in their tests, e.g. to
simulate an update.
What I'm trying to solve here is that it's often the case that we want
to keep metadata from the previous commit without having to be too
verbose (i.e. reading from the parent, then passing it as an argument).
The new `--keep-metadata` switch makes this really easy. I intend to use
this in the rpm-ostree testsuite to make sure we always carry over the
`source-title` metadata as well as during set up for tests that require
`rpmostree.rpmdb.pkglist` metadata.
I initially implemented this in a small wrapper script that uses the API
directly, though we make use of so many other `ostree commit` functions
that it'd require re-implementing a lot of it.

This tripped up the `docbook-dtds` `%post` in my experiments
with doing rpm-ostree for buildroots.
I cloned and built [xfstests](https://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git)
but haven't yet investigated actually running it.
In the meantime let's do the obvious fix here; we need to distinguish
between "copyup enabled" and "actually did a copyup" in the open path
at least, since if we didn't do a copyup we don't need to re-open.

We had this basically forced on in the CLI; down the line I'd really like to

Today the rpm-ostree test suite uses `refs --create` to save
commits. I think this is a legitimate use case, and other
people may be doing something similar.
On the other hand, I think we should probably be changing the rpm-ostree test

we hit a real-world case where something needed to change.

A while ago I did `truncate -s 0 /path/to/repo/00/123.commit`, and expected a
checksum error, but I actually got a validation error due to us loading the
commit into a variant and trying to parse out the parent checksum, etc.
I first started by changing the `load_and_fsck_one_object()` function to
checksum before loading, but the problem is that we do a traverse of all objects
first. Fixing this is going to require an `OSTREE_REPO_COMMIT_TRAVER_FLAG_FSCK`
or something.
In the meantime at least though, let's add a public API to fsck a single object
which *does* checksum cleanly before parsing the object, and change the `fsck`
command to use it.
We then change the fsck binary to do this while iterating over the refs
and finding the commit object. This way we'll at least get a checksum
first for commit objects, even if not dirtree/dirmeta.

I was seeing the `Writing OSTree commit...` phase of rpm-ostree
being very slow lately. This turns out to be more fallout from
https://github.com/ostreedev/ostree/pull/1170
AKA commit: 8fe4536
Loading the xattrs is slow on my system (F27AW, XFS+LVM, NVMe). I haven't fully
traced through why, but AIUI at least on XFS the xattrs are often stored outside
of the inode so it's a little bit like doing an `open()+read()`. Plus there's
the LSM overhead, etc.
The thing is that for rpm-ostree's package layering use case, we
basically always want to treat the on-disk state as canonical. (There's
a subtle case here if one does overrides for something that contains
policy but we'll fix that).
Anyways, so we're in a state now where we do the slow but correct thing by
default, which seems sane. But let's allow the app to opt-in to telling us
"really trust devino". The difference between a `stat()` + hash table lookup
versus the full xattr load on my test case of `rpm-ostree install
./tree-1.7.0-10.fc27.x86_64.rpm` is absolutely dramatic; consistently on the
order of 10s without this support, and <1s with (800ms).
Closes: #1357

When using dynamic remotes (LAN and USB), we cannot use their name with
the common remote related ops (ostree_repo_remote_...) because ostree
doesn't keep this type of remotes in its internal hash table.
Unfortunately this means that we cannot access the URL of those remotes
either (in order to e.g. set the right URL for those remotes in
Flatpak).
Since the URL is actually stored in a key file that belongs to the
OstreeRemote, then we can simply allow users access to it through a
getter.
So this patch adds a method that allows to return the URL directly from
the OstreeRemote without having to go through the OstreeRepo.
The test-repo-finder-config is also updated by this patch to check if
the URL is correct.

A tricky thing here that caused this to go past a lot of our tests
is that the code was mostly OK if there was an available delta from
an older commit. But this case broke if we e.g. had a new OS
deployment and did a `--require-static-deltas` pull, i.e. the initial
state.
I cleaned up our "find static delta state" function to return an enumeration,
and extended it with an "already have the commit" state. A problem
I then hit is that we've historically fetched detached metadata for
non-delta pulls, even if the commit hasn't changed. I decided not to
do that for `--require-static-deltas` pulls for now; otherwise the
code gets notably more complex.

This is more subtle fallout from:

AKA commit: 8fe45362578a43260876134d6547ebd0bb2485c3
Before, if we found a devino cache hit, we'd use it unconditionally.
Recall that `bare-user` repositories are very special in that they're the only
mode where the on disk state ("physical state") is not the "real" state. The
latter is stored in the `user.ostreemeta` xattr. (`bare-user` repos are also
highly special in that symlinks are regular files physically, but that's not
immediately relevant here).
Since we now have `bare-user-only` for the "pure unprivileged container" case,
`bare-user` should just be used for "OS builds" which have nonzero uids (and
possibly SELinux labels etc.)
In an experimental tool I'm writing "skopeo2ostree" which imports OCI images
into refs, then squashes them together into a single final commit, we lost the
the `81` group ID for `/usr/libexec/dbus-1/dbus-daemon-launch-helper`.
This happened because the commit code was loading the "physical" disk state,
where the uid/gid are zero because that's the uid I happened to be using. We
didn't just directly do the link speedup because I was using `--selinux-policy`
which caused the xattrs to change, which caused us to re-commit objects from the
physical state.
The unit test I added actually doesn't quite trigger this, but I left
it because "why not". Really testing this requires the installed test
which uses SELinux policy from `/`.
The behavior without this fix looks like:
```
-00755 0 0 12 { [(b'user.ostreemeta', [byte 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x51, 0x00, 0x00, 0x81, 0xed]), (b'security.selinux', b'system_u:object_r:lib_t:s0')] } /usr/lib/dbus-daemon-helper
```
which was obviously totally broken - we shouldn't be picking up the
`user.ostreemeta` xattr and actually committing it of course.

This is a freeform string useful to track/display when a commit is "derived"
from some other format. For example, in the rpm-ostree test we make a
`vmcheck` ref that conceptually overlays the default ref like
`fedora-atomic:fedora/26/x86_64/atomic-host`.
My current patch sets the source title to e.g.
"Dev overlay on fedora-atomic:fedora/26/x86_64/atomic-host".
Another case I'm working on now is importing OCI images to use
as host images. For that case, the source title is
With this patch we could then set the original OCI image name + tag
as the source name, like:
"oci:cgwalters/demo-custom-fedora-atomic-host:26".

I'm playing around with some ostree ⇔ OCI/Docker bits, and ran
into this while importing an OCI image that built from the Fedora
base image where `/home` is a regular directory, and I added a layer
that did the ostree bits of moving it to `/var` and leaving a symlink.
OCI/Docker supports this. Now since "process whiteouts" is really the
"enable OCI/Docker" mode, let's only replace dirs if that's enabled.
This leaves the `UNION_FILES` targeted for its original use case
which is unioning components/packages. (Although that use case itself
is now a bit superceded by `UNION_IDENTICAL`, but eh).

Change the regexp for validating refs to require at least one letter or digit
before allowing the other special chars in the set `[.-_]`. Names that start
with `.` are traditionally Unix hidden files; let's ignore them under the
assumption they're metadata for some other tool, and we don't want to
potentially conflict with the special `.` and `..` Unix directory entries.
Further, names starting with `-` are problematic for Unix cmdline option
processing; there's no good reason to support that. Finally, disallow `_` just
on general principle - it's simpler to say that ref identifiers must start with
a letter or digit.
We also ignore any existing files (that might be previously created refs) that
start with `.` in the `refs/` directory - there's a Red Hat tool for content
management that injects `.rsync` files, which is why this patch was first
written.
V1: Update to ban all refs starting with a non-letter/digit, and
also add another call to `ostree_validate_rev` in the pull

For checkouts that are on the same device, for regular files we can simply
"adopt" existing files. This is useful in the "build from subtrees" pattern that
happens with e.g. `rpm-ostree install` as well as flatpak and gnome-continuous.
New files are things like an updated `ldconfig` cache, etc. And particularly for
`rpm-ostree` we always regenerate the rpmdb, which for e.g. this workstation is
`61MB`.
We probably should have done this from the start, and instead had a `--copy`
flag to commit, but obviously we have to be backwards compatible.
There's more to do here - the biggest gap is probably for `bare-user` repos,
which are often used with things like `rpm-ostree compose tree` for host
systems. But we can do that later.

There's a subtle issue going on with the way we use `UNION_IDENTICAL`
now in rpm-ostree. Basically, the crux of the issue is that we checkout
the whole tree from the system repo, but then overlay packages by
checking out from the pkgcache repo. This is an easy way to break the
assumption that we will be merging hardlinks from the same repo.
This ends up causing issues like:
https://github.com/projectatomic/rpm-ostree/issues/1047
There, `vim-minimal` is already part of the host and has an object for
`/usr/share/man/man1/ex.1.gz`. `vim-common` has that same file, but
because it's unpacked in the pkgcache repo first, the hardlinks are not
the same.
There are a few ways we *could* work around this in rpm-ostree itself,
e.g. by re-establishing hardlinks when we do the content pull into the
system repo, but it still felt somewhat hacky. Let's just do this the
proper way and fall back to checksumming the target file if needed,
which is what librpm does as well in this case. Note that we only
checksum if they're not hard links, but they're the same size.
