The [dev-overlay](332c6ab3b9/src/cmd-dev-overlay)
script shipped in coreos-assembler mostly exists to deal
with the nontrivial logic around SELinux policy. Let's make
the use case of "commit some binaries overlaying a base tree, using
the base's selinux policy" just require a magical
`--selinux-policy-from-base` argument to `ostree commit`.
A new C API was added to implement this in the case of `--tree=ref`;
when the base directory is already checked out, we can just reuse
the existing logic that `--selinux-policy` was using.
Requires: https://github.com/ostreedev/ostree/pull/2039
Add G_IO_ERROR_PARTIAL_INPUT to the list of error codes caused by
transient networking errors which lead us to retry the request. When
attempting to install the spotify flatpak you often get the error
message "Connection terminated unexpectedly" and the download of the deb
file fails. In this case, libsoup is setting G_IO_ERROR_PARTIAL_INPUT
and sometimes a subsequent download attempt is successful, so we should
treat it as transient.
Ideally we would behave as wget does in this case and retry the download
picking up where we left off in the file rather than starting over, but
that would require changes to libsoup I think.
Sadly this patch does not fix the flatpak installation of spotify in the
face of such errors, because flatpak doesn't use libostree to download
extra data, but presumably it's possible we could encounter such an
error pulling from an ostree repo, so the patch is still correct.
These had been added assuming 2019.7 would be the next version, but now
it's 2020 and there's been a release. In the case of
`OstreeCommitSizesEntry`, I'd forgotten to move it forward from 2019.5
to 2019.7 in the time between when I started working on the feature and
it landed.
For repo structure directories like `objects`, `refs`, etc... we should
be more permissive and let the system's `umask` narrow down the
permission bits as wanted.
This came up in a context where we want to be able to have read/write
access on an OSTree repo on NFS from two separate OpenShift apps by
using supplemental groups[1] so we don't require SCCs for running as the
same UID (supplemental groups are part of the default restricted SCC).

For some reason I haven't fully debugged (probably a recent
kernel change), in the case where the immutable bit isn't set,
trying to call `EXT2_IOC_SETFLAGS` without it set returns `EINVAL`.
Let's avoid calling the `ioctl()` if we don't have anything to do.
This fixes a slew of `make check` failures here in my toolbox
environment.
(kernel is `5.5.0-0.rc6.git0.1.fc32.x86_64` with `xfs`)
Using fs-verity is natural for OSTree because it's file-based,
as opposed to block based (like dm-verity). This only covers
files - not symlinks or directories. And we clearly need to
have integrity for the deployment directories at least.
Also, what we likely need is an API that supports signing files
as they're committed.
So making this truly secure would need a lot more work. Nevertheless,
I think it's time to start experimenting with it. Among other things,
it does *finally* add an API that makes files immutable, which will
help against some accidental damage.
This is basic enablement work that is being driven by
Fedora CoreOS; see also https://github.com/coreos/coreos-assembler/pull/876
Currently `ostree_gpg_verify_result_require_valid_signature` always
returns an error that the key used for the signature is missing from the
keyring. However, all that's been determined is that there are no valid
signatures. The error could also be from an expired signature, an
expired key, a revoked key or an invalid signature.
Provide values for these missing errors and return them from
`ostree_gpg_verify_result_require_valid_signature`. The description of
each result is appended to the error message, but since the result can
contain more than one signature but only a single error can be returned,
the status of the last signature is used for the error code. See the
comment for rationale.

This function parses the object listing in the `ostree.sizes` metadata
and returns an array of `OstreeCommitSizesEntry` structures.
Unfortunately, for reasons I don't understand, the linker wants to
resolve `_ostree_read_varuint64` from `ostree-core.c` even though it's
not used by `test-checksum.c` at all.
Append a byte encoding the OSTree object type for each object in the
metadata. This allows the commit metadata to be fetched and then for the
program to see which objects it already has for an accurate calculation
of which objects need to be downloaded.
This slightly breaks the `ostree.sizes` `ay` metadata entries. However,
it's unlikely anyone was asserting the length of the entries since the
array currently ends in 2 variable length integers. As far as I know,
the only users of the sizes metadata are the ostree test suite and
Endless' eos-updater[1]. The former is updated here and the latter
already expects this format.
1. https://github.com/endlessm/eos-updater/
If the object was already in the repo then the sizes metadata entry was
skipped. Move the sizes entry creation after the data has been computed
but before the early return for an existing object.
The object sizes hash table was only being cleared when the repo was
finalized. That means that performing multiple commits while the repo
was open would reuse all the object sizes metadata for each commit.
Clear the hash table when the sizes metadata is setup and when it's
added to a commit. This still does not fix the issue all the way since
it does nothing to prevent the program from constructing multiple
commits simultaneously. To handle that, the object sizes hash table
should be attached to the MutableTree since that has the commit state.
However, the MutableTree is gone when the commit is actually created.
The hash table would have to be transferred to the root file when
writing the MutableTree. That would be an awkward addition to
OstreeRepoFile, though. Add a FIXME to capture that.
We want to support extending the read-only state to cover `/sysroot`
and `/boot`, since conceptually all of the data there should only
be written via libostree. Or at least for `/boot` should *mostly*
just be written by ostree.
This change needs to be opt-in though to avoid breaking anyone.
Add a `sysroot/readonly` key to the repository config which instructs
`ostree-remount.service` to ensure `/sysroot` is read-only. This
requires a bit of a dance because `/sysroot` is actually the same
filesystem as `/`; so we make `/etc` a writable bind mount in this case.
We also need to handle `/var` in the "OSTree default" case of a bind
mount; the systemd generator now looks at the writability state of
`/sysroot` and uses that to determine whether it should have the
`var.mount` unit happen before or after `ostree-remount.service.`
Also add an API to instruct the libostree shared library
that the caller has created a new mount namespace. This way
we can freely remount read-write.
This approach extends upon in a much better way previous work
we did to support remounting `/boot` read-write.
Closes: https://github.com/ostreedev/ostree/issues/1265
This allows copying the state from one OstreeAsyncProgress object to
another, atomically, without invoking the callback. This is needed in
libflatpak, in order to chain OstreeAsyncProgress objects so that you
can still receive progress updates when iterating a different
GMainContext than the one that the OstreeAsyncProgress object was
created under.
See https://github.com/flatpak/flatpak/pull/3211 for the application of
this API.
Define an `OstreeKernelArgsEntry` structure, which holds
both the key and the value. The kargs order array stores
entries for each key/value pair, instead of just the keys.
The hash table is used to locate entries, by storing
entries in a pointer array for each key. The same public
interface is preserved, while maintaining ordering
information of each key/value pair when
appending/replacing/deleting kargs.
Fixes: #1859
To allow for FIPS mode, we need to also install the HMAC file from
`/usr/lib/modules` to `/boot` alongside the kernel image where the
`fips` dracut module will find it. For details, see:
https://github.com/coreos/fedora-coreos-tracker/issues/302
Note I didn't include the file in the boot checksum since it's itself a
checksum of the kernel, so we don't really gain much here other than
potentially causing an unnecessary bootcsum bump.
I was hitting `SIGSEGV` when running `cosa build` and narrowed it down
to #1954. What's happening here is that because we're using the default
context, when we unref it in the out path, it may not actually destroy
the `GSource` if it (the context) is still ref'ed elsewhere. So then,
we'd still get events from it if subsequent operations iterated the
context.
This patch is mostly a revert of #1954, except that we still keep a ref
on the `GSource`. That way it is always safe to destroy it afterwards.
(And I've also added a comment to explain this better.)
We're creating the timer source and then passing ownership to the
context, but because we didn't free the pointer, we would still call
`g_source_destroy` in the exit path. We'd do this right after doing
`unref` on the context too, which would have already destroyed and
unref'ed the source.
Drop that and just restrict the scope of that variable down to make
things more obvious.
Just noticed this after reviewing #1953.
In glib 2.62 this has been changed to emitting a warning. Use G_STRFUNC
instead, which has been available for a long time and is already used in
other places in ostree.
zipl is a bit special in that it parses the BLS config files
directly *but* we need to run the command to update the "boot block".
Hence, we're not generating a separate config file like the other
backends. Instead, extend the bootloader interface with a `post_bls_sync`
method that is run in the same place we swap the `boot/loader` symlink.
We write a "stamp file" in `/boot` that says we need to run this command.
The reason we use stamp file is to prevent the case where the system is
interrupted after BLS file is updated, but before zipl is triggered,
then zipl boot records are not updated.
This opens the door to making things eventually-consistent/reconcilable
by later adding a systemd unit to run `zipl` if we're interrupted via
a systemd unit - I think we should eventually take this approach
everywhere rather than requiring `/boot/loader` to be a symlink.

After the corruption has been fixed with "ostree fsck -a --delete", a
second run of the "ostree fsck" command will print X partial commits
not verified and exit with a zero.
The zero exit code makes it hard to detect if a repair operation needs
to be run. When ever fsck creates a partial commit it should add a
reason for the partial commit to the state file found in
state/<hash>.commitpartial. This will allow a future execution of the
fsck to still return an error indicating that the repository is still
in the damaged state, awaiting repair.
Additional reason codes could be added in the future for why a partial
commit exists.
Text from: https://github.com/ostreedev/ostree/pull/1880
====
cgwalters commented:
To restate, the core issue is that it's valid to have partial commits
for reasons other than fsck pruned bad objects, and libostree doesn't
have a way to distinguish.
Another option perhaps is to write e.g. fsck-partial into the
statefile state/<hash>.commitpartial which would mean "partial, and
expected to exist but was pruned by fsck" and fsck would continue to
error out until the commit was re-pulled. Right now the partial stamp
file is empty, so it'd be fully compatible to write a rationale into
it.

If there are different deployments for the same commit version, the BLS
snippets will have the same title fields (but different version fields):
$ grep title *
ostree-1-testos.conf:title TestOS 42 20190902.0 (ostree)
ostree-2-testos.conf:title TestOS 42 20190902.0 (ostree)
ostree-3-testos.conf:title TestOS 42 20190902.0 (ostree)
But bootloaders could expect the title field to be unique for BLS files.
For example, the zipl bootloader used in the s390x architecture uses the
field to name the boot sections that are created from the BLS snippets.
So two BLS snippets having the same title would lead to zipl failing to
create the IPL boot sections because they would have duplicated names:
$ zipl

Error: Config file '/etc/zipl.conf': Line 0: section name 'TestOS 42 20190902.0 (ostree)' already specified
Avoid this by always including the deployment index along with the commit
version in the title field, so this will be unique even if there are BLS
files for deployments that use the same commit version:
$ grep title *
ostree-1-testos.conf:title TestOS 42 20190902.0 (ostree:2)

Currently the BLS fragments fields write is non-determinisitc. The order
of the fields will depend on how the iterator of the options GHashTable
iterates over the key/value pairs.
But some bootloaders expect the fields to be written in a certain order.
For example the zipl bootloader (used in the s390x architecture) fails to
parse BLS files if the first field is not the 'title' field, since that's
used to name the zipl boot sections that are created from the BLS files.
Write the fields in a deterministic order, following what is used in the
example file of the BootLoaderspec document:

OSTree has some logic to preserve comment lines in the BLS fragments, but
the BLS fragments are always created on new deployments so the comments
are never carried.
Also, OSTree never writes BLS fragments with comments so these will only
be present in BLS files that were modified outside of OSTree. Something
that should be avoided in general.
Finally, there is a bug in the logic that causes BLS files to have lines
with only a newline character.
The ostree_bootconfig_parser_parse_at() function reads the bootconfig file
using glnx_fd_readall_utf8() but this function NUL terminates the returned
string with the file contents.
So when the string is later split using '\n' as delimiter, the last token
is set to '\0' and a wrong GVariant will be added to the lines GPtrArray
in the OstreeBootconfigParser struct.
This will lead to bootconfig files that contains lines with only a newline
character, since the key in the GVariant would be set to NUL and won't be
present in the options GHashTable of the OstreeBootconfigParser struct.
So let's just remove that logic since is never used and makes BLS files to
have wrong empty lines.

that's only available on gnupg 2.2 or newer. Possibly this code can be
dropped later when that's more widely deployed or users/distros have
been advised to backport the necessary changes.

Otherwise, we'll be subject to whatever `umask` is currently. Normally,
processes should respect `umask` when creating files and directories,
but specifically for `ostree admin unlock` (or `rpm-ostree usroverlay`),
this poses a problem since e.g. a `/usr` with mode 0700 will break any
daemon that doesn't run as root and needs to read files under `/usr`,
such as polkitd.
This patch just does a `chmod()` after the `mkdir()`. An alternative
would be to do `umask(0000)` after forking into the child process
that'll call `mount()`, but that'd require also moving the `mkdir()`
calls into there, making for a more intrusive patch.

Currently for a "normal" refspec you can choose to use
ostree_repo_resolve_rev_ext() instead of ostree_repo_resolve_rev() if
you only want to look at local refs (in refs/heads/) not remote ones.
This commit provides the analogous functionality for
ostree_repo_resolve_collection_ref() by adding a flag
OSTREE_REPO_RESOLVE_REV_EXT_LOCAL_ONLY and implementing it. This
will be used by Flatpak.
Closes: #1825

Currently the flag OSTREE_REPO_LIST_REFS_EXT_EXCLUDE_REMOTES for
ostree_repo_list_collection_refs() means that refs in refs/remotes/
should be excluded but refs in refs/mirrors/ should still be checked, in
addition to refs/heads/ which is always checked. However in some
situations you want to exclude both remote and mirrored refs and only
check local "owned" ones. So this
commit adds a new flag OSTREE_REPO_LIST_REFS_EXT_EXCLUDE_MIRRORS which
lets you exclude refs/mirrors/ from the listing.
This way we can avoid breaking API but still allow the listing of local
collection-refs.
The impetus for this change is that I'm changing Flatpak to make more
use of refs/mirrors, and we need a way to specify that a collection-ref
is local when using ostree_repo_resolve_collection_ref() in, for
example, the implementation of the repo command. The subsequent commit
will make the changes needed there.

My last commit "lib/repo-refs: Resolve collection-refs in-memory and in
parent repos" changed ostree_repo_resolve_collection_ref() to check the
in-memory set of refs *after* failing to find the ref on disk but that's
not what we want. We want to use the in-memory set of refs first,
because those are the most up to date commits, and then fall back to the
on-disk repo and finally fall back to checking any parent repo. This
commit makes such a change to the order of operations, which is
consistent with how ostree_repo_resolve_rev() works.
Aside from this change being logical, it also fixes some unit test
failures on an unmerged branch of flatpak:

Currently the P2P code requires you to trust every remote you have
configured to the same extent, because a remote controlled by a
malicious actor can serve updates to refs (such as Flatpak apps)
installed from other remotes.[1] The way this attack would play out is
that the malicious remote would deploy the same collection ID as the
victim remote, and would then be able to serve updates for it.
One possible remedy would be to make it an error to configure remotes
such that two have the same collection ID but differing GPG keys. I
attempted to do that in Flatpak[2] but it proved difficult because it is
valid to configure two remotes with the same collection ID, and they may
then each want to update their keyrings which wouldn't happen
atomically.
Another potential solution I've considered is to add a `trusted-remotes`
option to ostree_repo_find_remotes_async() which would dictate which
keyring to use when pulling each ref. However the
ostree_repo_finder_resolve_async() API would still remain vulnerable,
and changing that would require rewriting a large chunk of libostree's
P2P support.
So this commit represents a third attempt at mitigating this security
hole, namely to have the client specify which remote to use for GPG
verification at pull time. This way the pull will fail if the commits
are signed with anything other than the keys we actually trust to serve
updates.
This is implemented as an option "ref-keyring-map" for
ostree_repo_pull_from_remotes_async() and
ostree_repo_pull_with_options() which dictates the remote to be used for
GPG verification of each collection-ref. I think specifying a keyring
remote for each ref is better than specifying a remote for each
OstreeRepoFinderResult, because there are some edge cases where a result
could serve updates to refs which were installed from more than one
remote.
The PR to make Flatpak use this new option is here[3].

In Silverblue right now, the boot menu title looks like this:
Fedora 29.20190301.0 (Workstation Edition) 29.20190301.0 (ostree)
This is because RPM-OSTree's `mutate-os-release` feature is enabled,
which injects the OSTree version string directly into `VERSION` and
`PRETTY_NAME`. So appending the version string again is a bit redundant.
Let's just do a simple substring check here before adding the version to
the title.

The sysroot.bootloader key configures the bootloader
that OSTree uses when deploying a sysroot. Having this key
allows specifying behavior not to use the default bootloader
backend code, which is preferable when creating a first
deployment from the sysroot (#1774).
As of now, the key can take the values "auto" or "none". If
the key is not given, the value defaults to "auto".
"auto" causes _ostree_sysroot_query_bootloader() to be used
when writing a new deployment, which is the original behavior
that dynamically detects which bootloader to use.
"none" avoids querying the bootloader dynamically. The BLS
config fragments are still written to
sysroot/boot/loader/entries for use by higher-level software.
More values can be supported in future to specify a single
bootloader, different behavior for the bootloader code, or
a list of bootloaders to try.

Currently the behavior of ostree_repo_resolve_rev() is that it tries to
resolve a ref to a commit by checking the refs/ directories, but also by
checking for in-memory ref-checksum pairs which are part of an
in-progress transaction and also by checking the parent repo if one
exists. Currently ostree_repo_resolve_collection_ref() only checks the
refs/ directories, so this commit makes its behavior analagous since it
is the analagous API which supports collection-refs.
The impetus for this was that currently Flatpak uses
ostree_repo_resolve_rev() to load a commit after doing a P2P pull in
flatpak_dir_do_resolve_p2p_refs(), but that assumes the ref came from
the same remote that originally provided it, which might not be the case
if more than one remote has the same collection ID configured. And
changing Flatpak to use ostree_repo_resolve_collection_ref() doesn't
work without this patch.

We want a case where we can disable the min-free-space check. Initially,
it felt like to add a OSTREE_REPO_PULL_FLAGS_DISABLE_FREE_SPACE_CHECK but
the problem is prepare_transaction() does not have a OstreeRepoPullFlags
parameter which we can parse right here. On top of it, prepare_transaction()
enforces min-free-space check and won't let the transaction proceed if
the check failed.
This is pretty bad in conjunction with "inherit-transaction" as what
Flatpak uses. There is no way to disable this check unless we remove
it altogether from prepare_transaction.
This issue came out to light when flatpak wasn't able to write metadata
after fetching from remote:
[uajain@localhost ~]$ flatpak remote-info flathub org.kde.Platform//5.9
error: min-free-space-size 500MB would be exceeded
Metadata objects helps in housekeeping and restricting them means
restricting crucial UX (like search, new updates) functionalities
in clients like gnome-software. The error banners originated from
these issues are also abrupt and not much helpful to the user. This
is the specific instance of the issue this patches tries to address.

This allows specifying gpgpath as list of
paths that can point to a file or a directory. If a directory path
is given, paths to all regular files in the directory are added
to the remote as gpg ascii keys. If the path is not a directory,
the file is directly added (whether regular file, empty - errors
will be reported later when verifying gpg keys e.g. when pulling).
Adding the gpgkeypath property looks like:

Rather than manually starting the `ostree-finalize-staged.service` unit,
we can leverage systemd's path units for this. It fits quite nicely too,
given that we already have a path we drop iif we have a staged
deployment.
To give some time for the preset to make it to systems, we don't yet
drop the explicit call to `systemctl start`. Though we do make it
conditional based on a DEBUG env var so that we can actually test it in
CI for now. Once we're sure this has propagated, we can drop the
`systemctl start` path and the env var together.
