We use a similar trick to having a `sysroot -> .` symlink on the real root
here to support both /boot on root as well as on a separate filesystem. No
matter how it's mounted `/boot/xyz` will always refer to the file you'd
expect.
This is nicer than my previous attempts at this because there's no
configuration nor auto-detection required.
The "new style" code generally avoids `goto err` because it conflicts
with `__attribute__((cleanup))`. This fixes a compiler warning.

If `glnx_make_lock_file` falls back to `flock`, on NFS this uses POSIX
locks (`F_SETLK`). As such, we need to be able to handle `EACCES` as
well as `EAGAIN` (see `fnctl(2)`).
I think this is what coreos-ostree-importer has been hitting, which runs
on RHEL7 in the Fedora infra and does locking over an NFS share where
multiple apps could concurrently pull things into the repo.
This came in with 5af403be0c but
was never implemented.
I noticed this now because the Rust ostree bindings generate a
wrapper for it which the linker tries to use.
And move everything that was in it directly in `ci/`. There's a bunch
more cleanups here that we need to do (and more changes to upstream from
the rpm-ostree copies of this).
This is the dual of 1f3c8c5b3d
where we output more detail when signapi fails to validate.
Extend the API to return a string for success, which we output
to stdout.
This will help the test suite *and* end users validate that the expected
thing is happening.
In order to make this cleaner, split the "verified commit" set
in the pull code into GPG and signapi verified sets, and have
the signapi verified set contain the verification string.
We're not doing anything with the verification string in the
pull code *yet* but I plan to add something like
`ostree pull --verbose` which would finally print this.
To aid debuggability, when we find a commit that isn't signed
by our expected key, output a specific error message with the
key.
(And then add code to switch to just printing the count beyond 3
because the test suite injects 100 keys and hopefully no one
ever actually does that)
I'm thinking about adding an implementation of ed25519 signatures
with OpenSSL (so we can ship the feature with Fedora CoreOS
without requiring an additional library) and in preparation for
that it's essential that we validate that libsodium-generated
signatures and OpenSSL-generated signatures are compatible.
I don't know if they are yet actually, but the goal of this
new test is to add a pre-generated repository with a signed
commit generated by libsodium.
This will catch if e.g. there's ever a change in libsodium,
or if existing libsodium implementation versions (e.g. the
one in Debian) might differ from what we ship here.
Align with --from-file and use 'FILE' instead of 'PATH' as option
argument string. No functional change, this is only cosmetics.

Add a standard key for this. We actually had a case in OpenShift
builds recently where a `ppc64le` image was pushed over an `x86_64`
one and this started failing at runtime with a not immediately
obvious error.
I'll probably end up changing rpm-ostree at least to use
the RPM architecture for this key and fail if it doesn't match
the booted value.
Possibly that should live in ostree but it would involve adding
architecture schema here, which gets into a big mess. Let's
just standardize the key.
xref e02ef2683d
Add support for a devicetree directory at /usr/lib/modules/$kver/dtb/.
In ARM world a general purpose distribution often suppports multiple
boards with a single operating system. However, OSTree currently only
supports a single device tree, which does not allow to use the same
OSTree on different ARM machines. In this scenario typically the boot
loader selects the effective device tree.
This adds device tree directory support for the new boot artefact
location under /usr/lib/modules. If the file `devicetree` does not
exist, then the folder dtb will be checked. All devicetrees are hashed
into the deployment hash. This makes sure that even a single devicetree
change leads to a new deployment and hence can be rolled back.
The loader configuration has a new key "devicetreepath" which contains
the path where devicetrees are stored. This is also written to the
U-Boot variable "fdtdir". The boot loader is expected to use this path
to load a particular machines device tree from.

One OpenShift user saw this from rpm-ostree:
```
client(id:cli dbus:1.583 unit:machine-config-daemon-host.service uid:0) added; new total=1
Initiated txn UpdateDeployment for client(id:cli dbus:1.583 unit:machine-config-daemon-host.service uid:0): /org/projectatomic/rpmostree1/rhcos
Txn UpdateDeployment on /org/projectatomic/rpmostree1/rhcos failed: File header size 4294967295 exceeds size 0
```
which isn't very helpful. Let's add some error
prefixing here which would at least tell us which
object was corrupted.
