g_memdup() is subject to an integer overflow on 64-bit machines if the
object being copied is larger than UINT_MAX bytes. I suspect none of
these objects can actually be that large in practice, but it's easier
to replace all the calls than it is to assess whether we need to
replace them.
A backport in libglnx is used on systems where GLib is older than 2.68.x.

This was only there to reproduce a bug we hit long ago
with bootloader file ordering. We're extremely unlikely
to reintroduce such a bug, and it's not worth carrying around
this code.
As noted in readdir(3), in the presence of long filenames it is
possible for a directory entry to be larger than `sizeof (struct dirent)`.
Copy the full length instead.

Introduces an intermediate format for overlayfs storage, where
.wh-ostree. prefixed files will be converted into char 0:0
whiteout devices used by overlayfs to mark deletions across layers.
The CI scripts now uses a volume for the scratch directories
previously in /var/tmp otherwise we cannot create whiteout
devices into an overlayfs mounted filesystem.
Related-Issue: #2712
If `/boot` is an automount, then the unit will be stopped as soon as the
automount expires. That's would defeat the purpose of using systemd to
delay finalizing the deployment until shutdown. This is not uncommon as
`systemd-gpt-auto-generator` will create an automount unit for `/boot`
when it's the EFI System Partition and there's no fstab entry.
To ensure that systemd doesn't stop the service early when the `/boot`
automount expires, introduce a new unit that holds `/boot` open until
it's sent `SIGTERM`. This uses a new `--hold` option for
`finalize-staged` that loads but doesn't lock the sysroot. A separate
unit is used since we want the process to remain active throughout the
finalization run in `ExecStop`. That wouldn't work if it was specified
in `ExecStart` in the same unit since it would be killed before the
`ExecStop` action was run.

This is to support pending deployments instead of rasing assertion.
For example:
```
$ sudo rpm-ostree kargs --append=foo=bar
$ sudo ostree admin kargs edit-in-place --append-if-missing=foobar
```
After reboot we get both `foo=bar foobar`.
Fix https://github.com/ostreedev/ostree/issues/2679
In the current "ostree native container" flow, we're inserting
a commit object into the repo but with no refs.
We have hacks in a few places to find the commit digest via e.g.
`find repo/objects -name *.commit` but that's a horrible hack.
Add `ostree rev-parse --single` which will print the single commit,
and error out if there is not exactly one commit.

Don't parse `rpm-ostree status` output, it's not meant for that. Use
`--json` output instead.
While we're here, fix an obsolete reference to Ansible.

https://github.com/coreos/coreos-assembler/pull/2921 broke this
test which is intentionally causing a systemd unit to fail.
As they say, necessity is the mother of invention. They don't
say though that need always causes particularly *beautiful* things
to be invented...
update all existing deployments in place
Example:
$ sudo ostree admin kargs edit-in-place --append-if-missing=rw
See https://github.com/ostreedev/ostree/issues/2617
This will not add duplicate key, if there is `TESTARG=VAL1` in the
kernel arguments, `--append-if-missing=TESTARG=VAL2` will be ignored.
Not all filesystems support extended attributes. This test uses
/var/tmp to try to get an extended-attributes-capable filesystem,
but that might not succeed.

$ cargo fix --edition
note: Switching to Edition 2021 will enable the use of the version 2 feature resolver in Cargo.
This may cause some dependencies to be built with fewer features enabled than previously.
More information about the resolver changes may be found at https://doc.rust-lang.org/nightly/edition-guide/rust-2021/default-cargo-resolver.html
When building the following dependencies, the given features will no longer be used:
libc v0.2.126 removed features: extra_traits
The following differences only apply when building with dev-dependencies:
getrandom v0.2.6 removed features: std
```
which looks OK to me.
I messed this up; the last release should inherit from the previous
release (N-1) and not the previous to that (N-2).
I think (hope) this isn't an ABI break...
Just noticed this when I was going to add a new symbol.
I'm aiming to do some more work on the Rust side around `fsck`
like functionality, and this is a useful primitive. There isn't
a great Rust crate for xattrs, and I think it's better to share this
code.
Fix up the paths for the crates now that the Rust bindings are in
`rust/`.
We can't today include the test suite because it depends on `ostree-rs-ext`
which would make everything circular.
(Building that now requires a separate `cd tests/inst && cargo build`)
Quite a while ago we added staged deployments, which solved
a bunch of issues around the `/etc` merge. However...a persistent
problem since then is that any failures in that process that
happened in the *previous* boot are not very visible.
We ship custom code in `rpm-ostree status` to query the previous
journal. But that has a few problems - one is that on systems
that have been up a while, that failure message may even get
rotated out. And second, some systems may not even have a persistent
journal at all.
A general thing we do in e.g. Fedora CoreOS testing is to check
for systemd unit failures. We do that both in our automated tests,
and we even ship code that displays them on ssh logins. And beyond
that obviously a lot of other projects do the same; it's easy via
`systemctl --failed`.
So to make failures more visible, change our `ostree-finalize-staged.service`
to have an internal wrapper around the process that "catches" any
errors, and copies the error message into a file in `/boot/ostree`.
Then, a new `ostree-boot-complete.service` looks for this file on
startup and re-emits the error message, and fails.
It also deletes the file. The rationale is to avoid *continually*
warning. For example we need to handle the case when an upgrade
process creates a new staged deployment. Now, we could change the
ostree core code to delete the warning file when that happens instead,
but this is trying to be a conservative change.
This should make failures here much more visible as is.
On systems where `coreutils` are built with `--enable-single-binary=symlinks` like Nix,
`/usr/bin/env` is symlinked to `/usr/bin/coreutils` and uses `argv[0]` to determine which program to run.
Since the `test-cli-extensions.sh` created a new symlink named `ostree-env`,
coreutils would be confused about the utility to choose, so running it would fail:
ostree-env: unknown program ‘ostree-env’
Try 'ostree-env --help' for more information.

I was reading this thread

For now let's just go back to having a static list of functions.
We don't have *too* many of those.
If we use head(1) to take only the first two lines, then cut(1) and
earlier pipeline entries are killed by SIGPIPE (if they have not already
terminated), and that's flagged as an error under `set -o pipefail`.
Use an equivalent sed command to take exactly the second line, but
without SIGPIPE.
