Matthew Leeds 972a1921f5 man: Add man page for create-usb

Matthew Leeds cf78888401 create-usb: Update summary in destination repo
Currently the create-usb command only generates a summary file in the
destination repo if one doesn't already exist, which means if one does
exist it becomes out of date after the new refs are pulled. This commit
makes ostree regenerate the summary regardless of whether it exists, so
that consumers such as ostree_repo_find_remotes_async() (and at a higher
level, GNOME Software) get an accurate picture of the refs available on
the mount. This commit also updates one of the unit tests to check that
the summary is accurate after a second pull into the same repo.

Since any user of the create-usb command is using collection IDs they
are new enough to be using the unsigned summary support. While it would
technically be possible to use summary signatures on a repo and use the
create-usb command on it (a scenario broken by this commit), the
create-usb command is designed for P2P distribution of refs, which
requires use of unsigned summary support. So this is a legitimate
narrowing of the tool.

Sam Spilsbury 002e5eeac6 avahi: Don't complain with g_warning if the daemon wasn't running
This is a normal case when running unit tests in client code
on continuous integration infrastructure. When those tests are
running they will set G_DEBUG=fatal-warnings which will cause
the program to abort if a warning is emitted. Instead, emit
a debug message if the problem was that we couldn't connect to
the daemon.

Colin Walters 16d3359bf8 lib/sysroot: Move staged into deployment list, rework handling
Followup to: https://github.com/ostreedev/ostree/pull/1503
After starting some more work on on this in rpm-ostree, it is
actually simpler if the staged deployment just shows up in the list.

It's effectively opt-in today; down the line we may make it the default,
but I worry about breaking things that e.g. assume they can mutate
the deployment before rebooting and have `/etc` already merged.

There's not that many things in libostree that iterate over the deployment
list.  The biggest change here is around the
`ostree_sysroot_write_deployments_with_options` API.  I initially
tried hard to support a use case like "push a rollback" while retaining
the staged deployment, but everything gets very messy because that
function truly is operating on the bootloader list.

For now what I settled on is to just discard the staged deployment;
down the line we can enhance things.

Where we then have some new gymnastics is around implementing
the finalization; we need to go to some effort to pull the staged
deployment out of the list and mark it as unstaged, and then pass
it down to `write_deployments()`.

This is a big change to the ostree model for hosts,

the other problem of racing with programs that modify `/etc`
such as LVM backups:

Matthew Leeds cb3360fca6 lib/repo: Add timestamps to OstreeRepoFinderResult
Currently OstreeRepoFinderResult, a data structure used by pull code
that supports P2P operations, has a hash table mapping refs to checksums
but doesn't include timestamp information. This means that clients have
no way of knowing just from the OstreeRepoFinderResult information if a
commit being offered by a peer remote is an update or downgrade until
they start pulling it. The client could check the summary or the commit
metadata for the timestamps, but this requires adding the temporary
remotes to the repo config, and ostree is already checking timestamps
before returning the results, so I think it makes more sense for them to
be returned rather than leaving it to the client. This limitation is
especially important for offline computers, because for online computers
the latest commit available from any remote is the latest commit,
period.

This commit adds a "ref_to_timestamp" hash table to
OstreeRepoFinderResult that is symmetric to "ref_to_checksum" in that it
shares the same keys. This is an API break, but it's part of the
experimental API, and none of the current users of that (flatpak,
eos-updater, and gnome-software) are affected. See the documentation for
more details on "ref_to_timestamp". One thing to note is the data
structure currently gets initialized in find_remotes_cb(), so only users
of ostree_repo_find_remotes_async() will get them, not users of, say,
ostree_repo_finder_resolve_all_async(). This is because the individual
OstreeRepoFinder implementations don't currently access the timestamps
(but I think this could be changed in the future if there's a need).

This commit will allow P2P support to be added to
flatpak_installation_list_installed_refs_for_update, which will allow
GNOME Software to update apps from USB drives while offline (it's
already possible online).

Alexander Larsson c4c2b5ebd1 pull: Don't save summary to cache before validating signatures
In case of some kind of race or other weirdness we might be getting
non-matching versions of summary.sig and summary, where summary.sig
is the latest version. Currently we're saving them to the cache
directly after downloading them successfully, but they will then fail
to gpg validate. Then on the next run we'll keep using the cached files
even if they are incorrect, until summary.sig changes upstream.

This changes the order so that we verify the signatures before saving
to the cache, thus ensuring that we don't end up in a stuck state.

Matthew Leeds b190982ee6 lib/repo-pull: Improve error message when no summary is found
In ostree_repo_remote_fetch_summary_with_options(), if no summary is
found on the server and summary verification is enabled, the error
message implies that it's the summary signature that's missing, which is
misleading. This commit adds a more specific error message for the case
of a missing summary, which has the side effect of explicitly checking
for the case that signatures != NULL && summary == NULL after
repo_remote_fetch_summary(), even though that should never happen.

One effect of this is that if you run "flatpak remote-add" with an
incorrect URL you get a more helpful error message, and similarly for
other flatpak operations and other users of ostree.

typically used when you want a shared, immutable base.

EACCES, making it impossible to install via the system helper.

Matthew Leeds 9721be34e1 libotutil/checksum-utils: Fix memory management
Ostree uses the OtChecksum data structure as a wrapper around GChecksum
(depending on what libraries are available at compile time). According
to the docs for g_checksum_get_digest(), a GChecksum value can no longer
be updated after that function is called. Ostree enforces this by
setting "initialized" to FALSE after getting the digest, but this leads
to ot_checksum_clear() avoiding freeing any memory, leading to leaks. So
this commit adds a "closed" value that gets set when getting a digest
and checked when updating the value, so the initialized value can be
used only for memory management.

Colin Walters 5b3f79d4bb sysroot: Rework how we find booted deployment
I was looking at this code in prep for "staging" deployments,
and there are several cleanups to be made here.  The first
thing I noticed is that we look for the `ostree=` kernel argument,
but the presence of that should be exactly equivalent to having
`/run/ostree-booted` exist.  We just added a member variable for
that, so let's make use of it.

Related to this, we were erroring out if we had the karg but
didn't find a deployment.  But this can happen if e.g. one is
using `ostree admin --sysroot` from an ostree-booted system!  It's
actually a bit surprising no one has reported this so far; I guess
in the end people are either using non-ostree systems or running
from containers.

Let's add a member variable `root_is_sysroot` that we can use
to determine if we're looking at `/`.  Then, our more precise
"should find a booted deployment" state is when both `ostree_booted`
and `root_is_sysroot` are TRUE.

Next, rather than walking all of the deployments after parsing,
we can inline the `fstatat()` while parsing.  The mild ugly
thing about this is assigning to the sysroot member variable while
parsing, but I will likely clean that up later, just wanted to avoid
rewriting everything in one go.

Giuseppe Scrivano 127d8bb846 commit: add logic for .payload-link
When a new object is added to the repository, create a
$PAYLOAD-SHA256.payload-link symlink file as well.  The target of the
symlink is the checksum of the object that was added the repository.

Whenever we add a new object file, in addition to lookup if the file is
already present with the same checksum we also check if an object with
the same payload is in the repository.

If a file with the same payload is already present in the repository, we
copy it with `glnx_regfile_copy_bytes` that internally attempts to
create a reflink (ioctl (..., FICLONE, ..)) to the target file if the
file system supports it.  This enables to have objects that share the
payload but have a different inode and xattrs.

By default the payload-link-threshold value is G_MAXUINT64 that disables
the feature.

directory, not the ostree repo used by flatpak, which is at
"var/lib/flatpak/repo". So this commit changes the path so the repo can

Matthew Leeds 5848de93a4 lib/pull: Properly remove temporary remotes
For P2P pulls ostree adds temporary remotes and removes them in
find_remotes_cb(). However, if an OstreeRepoFinderResult gets freed
during the course of that function, the OstreeRemote in the result is
freed but a pointer to it remains in the remotes_to_remove array. This
means that when _ostree_repo_remove_remote() gets called on it at the
end of the function it will fail. In my case the resulting error was
"OSTree-CRITICAL **: _ostree_repo_remove_remote: assertion 'remote->name

* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted

William Manley 720e2ec9bc Add support for devicetree files alongside the kernel and initramfs
Much like the (optional) initramfs at
`/usr/lib/ostree-boot/initramfs-<SHA256>` or
`/usr/lib/modules/$kver/initramfs` you can now optionally include a
flattened devicetree (.dtb) file alongside the kernel at
`/usr/lib/ostree-boot/devicetree-<SHA256>` or
`/usr/lib/modules/$kver/devicetree`.

This is useful for embedded ARM systems which need the devicetree file
loaded by the bootloader for the kernel to discover and initialise
hardware.  See https://en.wikipedia.org/wiki/Device_tree for more
information.

This patch was mostly produced by copy-pasting code for initramfs handling
and renaming `s/initramfs/devicetree/g`.  It's not beautiful, but it is
fairly straightforward.

It may be useful to extend device-tree support in a number ways in the
future.  Device trees dependant on many details of the hardware they
support.  This makes them unlike kernels, which may support many different
hardware variants as long as the instruction-set matches.  This means that
a ostree tree created with a device-tree in this manner will only boot on
a single model of hardware.  This is sufficient for my purposes, but may
not be for others'.

I've tested this on my NVidia Tegra TK1 device which has u-boot running
in syslinux-compatible mode.

This is necessary for booting my NVidia Tegra TK1 device.  It uses u-boot
with syslinux compatibility.  In the syslinux files that come with the
device this is called `FDT`, but u-boot treats `FDT and `DEVICETREE` as
synonyms.

Colin Walters 8e6e64a5ad lib: Validate metadata structure more consistently during pull
Previously we were doing e.g. `ot_util_filename_validate()` specifically inline
in dirtree objects, but only *after* writing them into the staging directory (by
default). In (non-default) cases such as not using a transaction, such an object
could be written directly into the repo.

A notable gap here is that `pull-local --untrusted` was *not* doing
this verification, just checksums.  We harden that (and also the
static delta writing path, really *everything* that calls
`ostree_repo_write_metadata()` to also do "structure" validation
which includes path traversal checks.  Basically, let's try hard
to avoid having badly structured objects even in the repo.

One thing that sucks in this patch is that we need to allocate a "bounce buffer"
for metadata in the static delta path, because GVariant imposes alignment
requirements, which I screwed up and didn't fulfill when designing deltas. It
actually didn't matter before because we weren't parsing them, but now we are.
In theory we could check alignment but ...eh, not worth it, at least not until
we change the delta compiler to emit aligned metadata which actually may be
quite tricky.  (Big picture I doubt this really matters much right now
but I'm not going to pull out a profiler yet for this)

The pull test was extended to check we didn't even write a dirtree
with path traversal into the staging directory.

There's a bit of code motion in extracting
`_ostree_validate_structureof_metadata()` from `fsck_metadata_object()`.

Then `_ostree_verify_metadata_object()` builds on that to do checksum
verification too.

Previously when initramfs-* was not found in a deployment's

With this patch, the behaviour changes to be - if initramfs-*

Gatis Paeglis 62cb078973 ostree-prepare-root: enabler for simpler kernel arg
With the current approach, when ostree-prepare-root is used
on the kernel command line as init=, it always assumes that
the next value in the argument list is a path to the sysroot.
The code for falling back to a default path (if none is provided),
would only work if init= is the last arg in the argument list.
We can not rely on that and have to explicitly provide the
path to the sysroot. Which defeats the purpose of a default
path selection code.

To keep command line neater assume that sysroot is on / when
using ostree-prepare-root as init. This probably is what most
people want anyways. Also _ostree_kernel_args* API assumes
that args are space separated list. Which is problematic for:
"init=${ostree}/usr/lib/ostree/ostree-prepare-root /" as it
gets split in two.

Jonathan Lebon 939791b4fa bin/commit: add --keep-metadata option
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.
