I think I'm hitting issues due to this while using the Rust bindings:
https://github.com/coreos/rpm-ostree/pull/3406#issuecomment-1033084956
The bindings for those APIs use `from_glib_full` which says:

The commit metadata `version` key is well established but getting it for
a remote commit is cumbersome since the commit object needs to be
fetched and loaded. Including it in the summary additional metadata
allows a much more convenient view of what each of the remote refs
represents.
This aligns all the assertion in the module. In particular, it gets
rid of all `g_return_val_if_fail` instances which may fail without
properly setting GError to the caller.
When we clean up from an error, for example copy_file_range() failing
while we generate a static delta (perhaps caused by
https://gitlab.gnome.org/GNOME/libglnx/-/issues/3 or by a
genuine write error), we might free a variant builder that has a
non-null parent. Previously, this caused infinite recursion and a stack
overflow, repeatedly freeing the same object, but Luca Bruno suggested
that the intention here appears to have been to free the parent object.
Partially resolves https://github.com/ostreedev/ostree/issues/2525
(the other bug reported in that issue needs to be resolved by updating
libglnx to a version where libglnx#3 has been fixed).

This tightens up the logic for opening a file while inspecting its
xattrs. The only codepath fetching xattrs from a FD is the one
handling 'bare' mode.
It also rearranges the else-assert flow, mostly for future-proofing.
Support for that file was added previously, but the testing lived in
rpm-ostree only. Let's add it here too.
In the process add a hidden `--lock-finalization` to `ostree admin
deploy` to make testing easier (though it could also be useful to update
managers driving OSTree via the CLI).
Otherwise, any future staged deployment will also automatically be
locked even if not requested. Likely we should fold the locking into the
primary `staged-deployment` serialized GVariant instead.
This reworks `ostree ls` top-level logic so that cancellation
tokens and error details are plumbed through all codepaths.
It also gets rid of all previous goto jumps.
We do implicitly have this data because we log timings via structured
metadata in a later journal entry, but it's quite common to lose
the structured metadata because a lot of tooling just grabs the default
syslog-compatible text from `journalctl`.
Let's be louder when we hit this case as a general rule too; I think
most people shipping ostree systems want to see if it's happening.

Basically there's a systemd bug where it's losing the `_netdev`
aspect of Ceph filesystem mounts. This means the network is taken
down before Ceph is unmounted. In turn, our invocation of `sync()`
blocks on Ceph, which won't succeed.
And this in turn manifests as a failure to transition to the new
deployment.
I initially did this patch to just rip out the global `sync()`. I
am pretty sure we don't need it anymore. We've been doing individual
`syncfs()` on `/sysroot` and `/boot` for a while now, and those
are the only filesystems we should be touching. But *proving* that
is a whole other thing of course.
To be conservative, let's instead just add a timeout of 5s on
our invocation of `sync()`. It doesn't return any information on
success/error anyways.
To allow testing without the `sync()` invocation, we also support
a new `OSTREE_SYSROOT_OPT_SKIP_SYNC=1` environment variable. For
staged deployments, this needs to be injected via e.g. systemd unit
overrides into `ostree-finalize-staged.service`.
Implementing this is a bit hairy - we need to spawn a thread. I
debated blocking in arecursive mainloop, but I think `g_cond_wait_until()`
is also fine here.
In fixing https://github.com/coreos/rpm-ostree/pull/3323
I felt that it was a bit ugly we're installing `/usr/bin/ostree-container`.
It's kind of an implementation detail. We want users to use
`ostree container`.
Let's support values outside of $PATH too.
For example, this also ensures that TAB completion for `ost` expands
to `ostree ` with a space.
This removes a 'g_setenv()' call, which could potentially be unsafe
in a multi-thread context.
The current libselinux codebase does not seem to check for
`LIBSELINUX_DISABLE_PCRE_PRECOMPILED`, so I think this has no effects
nowadays.
Additionally, I could not find any reference to it in libselinux
git history, so I'm not sure if it ever played any role at all.
My current understanding is that this is coming from version
incompatibilities between an older libselinux in the build environment
and a newer policy (with precompiled regexs) in the target.
But from the ML discussion I found, I think it eventually got
solved in a different way, possibly by avoiding the policy binary
caches.

This swaps the order of a couple of input sanity checks, in order
to fix a minor memory leak due to an early-return on the error
path.
Memory for the result is now allocated only after input has been
sanity-checked.
It fixes a static analysis warning highlighted by Coverity.
This adds build-time configuration logic to automatically detect

Fixes `Argument with 'nonnull' attribute passed null` by making
the code not exist at all anymore.
In upstream libsoup this code is gone too; it uses `GUri` from glib
which we probably could now too, but one thing at a time.
This adds some logic to detect and dispatch unknown subcommands to
extensions available in `$PATH`. Additional commands can be
implemented by adding relevant `ostree-$verb` binaries to the system.
As an example, if a `/usr/bin/ostree-extcommand` extension is provided,
the execution of `ostree extcommand --help` will be dispatched to that
as `ostree-extcommand extcommand --help`.
This is trying to address:
https://pagure.io/fedora-iot/issue/48
Basically we changed rpm-ostree to start doing a shared lock during
commit by default, but this broke because pungi is starting a process
doing a commit for each architecture, and then trying to regenerate
the summary after each one.
This patch is deleting a big comment with a rationale for why
summary regeneration should be exclusive. Point by point:
> This makes sure the commits and deltas don't get
> deleted while generating the summary.
But prune operations require an exclusive lock, which means that
data still can't be deleted when the summary grabs a shared lock.
> It also means we can be sure refs
> won't be created/updated/deleted during the operation, without having to
> add exclusive locks to those operations which would prevent concurrent
> commits from working.
First: The status quo *has* prevented concurrent commits from working!
There is no real locking solution to this problem. What we really
need to do here is regenerate the summary after each commit *or*
when the caller decides to do it and e.g. include deltas at the same
time.
It's OK if multiple threads race to regenerate the summary;
last-one-wins behavior here is totally fine.
We should only try to remount `/sysroot` if we're actually handling the
sysroot repo and the repo isn't writable. We already have public APIs to
check each of those, so let's use them.
Closes: #2485
This moves read-only sysroot checks upfront, so that they are not
intermixed with mount operations.
It has no immediate side-effects, but allow these check to be
independent from the rest of the mounting logic (and future changes
to it).
This adds a `MS_SILENT` flag to all `mount(2)` calls, reducing the
amount of kernel logs produced on each boot.
Those messages do not contain actionable details, and in the "mount
plus read-only remount" case they can easily become highly redundant.
In general, we're probably going to need to change most of our
`g_return_if_fail` to `g_assert`. The analyzer flags that
the function can return `NULL`, but the caller isn't prepared for
this.
In practice, let's abort.

This defines `OstreeRepoAutoTransaction` as a boxed type, in order
to support auto-generating bindings for it.
That first requires adding internal reference-counting to it, to
allow freely copying/freeing references to a single transaction guard.
This rewords errors and log messages in the functions which take care
of preparing sysroot in initramfs.
Depending on the boot flow, it is possible to reach this logic
with a sysroot mounted (unexpectedly) as read-only.
In that case, let's clearly point out the problematic mountpoint.
This enhances the auto-transaction logic, augmenting the scope of a
transaction guard.
It allows committing or aborting a transaction through its guard.
It also supports tracking the completion status of a transaction
guard, avoiding double commits/aborts, while retaining the auto-cleanup
logic.
https://bugzilla.redhat.com/show_bug.cgi?id=1945274 is an issue where a privileged
kubernetes daemonset is writing a socket into `/etc`. This makes ostree upgrades barf.
Now, they should clearly move it to `/run`. However, one option is for us to
just ignore it instead of erroring out. Some brief investigation shows that
e.g. `git add somesocket` is a silent no-op, which is an argument in favor of ignoring it.

This is nicer than having the caller parse the commit
object, or indirect via the `OstreeRepoFile*` object of the root.
Will be used in ostree-rs-ext around tar parsing.
This is part of `OstreeCommitModifier`, but I'm not using
that in some of the ostree-ext Rust code.
It just makes more sense as a direct policy API, where it should
have been in the first place. There's already support for
setting a policy object on a commit modifier, so that's all the
old API needs to do now.
There's a general Unix philosophy that "silence is golden".
However, when one is explicitly invoking an error check it's nice
to see explicit success.
We already print various statistics, so ending with a happy
note has no extra cost.
The logic for `--selinux-policy` ended up in the `--tree=dir`
path, but there's no reason for that. Fix the imported
labeling with `--tree=tar`. Prep for use with containers.
We had this bug because the previous logic was trying to avoid
duplicating the code for generic `--selinux-policy` and
the case of `--selinux-policy-from-base --tree=dir`.
It's a bit more code, but it's cleaner if we dis-entangle them.
This will be helpful for the "ostree native container" work in
https://github.com/ostreedev/ostree-rs-ext/
Basically in order to reuse GPG/signapi verification, we need
to support adding a remote, even though it can't be used via
`ostree pull`. (At least, not until we merge ostree-rs-ext into ostree, but
even then I think the principle stands)
for deltafiles the legacy_transaction_resuming flag is not used,
which will mark the commit as done, even if files are missing.
using already existing commitstate_is_partial function as fix
We're waaay overdue for this, it's been the default
in rpm-ostree for years, and solves several important bugs
around not capturing `/etc` while things are running.
Also, `ostree admin upgrade --stage` (should) become idempotent.
Closes: https://github.com/ostreedev/ostree/issues/2389
We have a bunch of APIs to do GPG verification of a commit,
but that doesn't generalize to signapi. Further, they
require the caller to check the signature status explicitly
which seems like a trap.
This much higher level API works with both GPG and signapi.
The intention is to use this in things that are doing "external
pulls" like the ostree-ext tar import support. There we will
get the commitmeta from the tarball and we want to verify it
at the same time we import the commit.

Since the test suite now covers this the test was failing on
a Fedora SELinux enabled host where we see `security.selinux`
even if not in the commit.
I was seeing an `EPERM` here which was confusing.
It turned out the real error was `EEXIST`.
Since we're referring to the original error, but we do a
lot of computation in the middle, we need to save errno.
This fixes some aspects of OstreeRepoAutoTransaction and re-aligns
it with the logic in flatpak. Specifically:
* link to the underlying repo through refcounting
* bridge internal errors to warning messages
* verify the input pointer type
This is a preparation step before exposing this logic as a public API.
As pointed out in the original review, `gpg-list-keys` fits better
alongside the existing `gpg-import`.
