Matthew Leeds 164b2aa35b Don't copy summary for collection-ref mirror subset pulls
When we're only pulling a subset of the refs available in the remote, it
doesn't make sense to copy the remote's summary (which may not be valid
for the local repo). This makes the check here match the one done
several lines above when we decide whether to error out if there's no
remote summary available.

This extends the fix in https://github.com/ostreedev/ostree/pull/935 for
the case of collection-refs.

Also, add a unit test for this issue, based on the existing one in
pull-test.sh.

Matthew Leeds cd37293b5a find-remotes: Add a --mirror option
This will be useful in the unit test added by the next commit. It just
passes OSTREE_REPO_PULL_FLAGS_MIRROR to the call to
ostree_repo_pull_from_remotes_async().

Colin Walters 9cb148c9b9 lib: Add error prefixing for sysroot load and repo open
Noticed this while writing tests for a core `ostree_sysroot_load()`
entrypoint.  And decided to do the same for `ostree_repo_open()`,
and while there also noted we had a duplicate error prefixing
for the open (more recently `glnx_opendirat()` automatically
prefixes with the path).

Denis Pynkin e2c601687b ostree-repo: improve error handling
Correctly return "error" from `ostree_repo_sign_commit()`
in case if GPG is not enabled.

Use glnx_* functions in signature related pull code for clear
error handling if GPG isn't enabled.

Colin Walters b3bbbd1542 repo/commit: Add support for --selinux-policy-from-base
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

Matthew Leeds 53d1efbaab lib/fetcher-util: retry download on G_IO_ERROR_PARTIAL_INPUT
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.

When we added the read-only sysroot support it broke using "raw"
`ostree pull` and `ostree refs --create` and all of the core repo
CLIs that just operate on a repo and not a sysroot.

Fixing this is a bit ugly as it "layer crosses" things even more.
Extract a helper function that works in both cases.

Jonathan Lebon 7085a50297 lib/repo: Create repo directories as 0775
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).

Colin Walters 0dd8dec2c9 deploy: Avoid trying to change immutable state unnecessarily
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`)

Colin Walters 58fa579b1b Initial fs-verity support
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

Dan Nicholson fbf5a94e0a ostree/trivial-httpd: Fix --autoexit with --daemonize and --log-file
When --autoexit is used with --daemonize and --log-file, the program
never exits when the root directory is deleted. I believe what happens
is that g_file_new_for_path triggers the glib worker context to be
started to talk to GVfs. Once the program forks, the parent exits and
the thread iterating the worker context is gone. The file monitor then
never receives any events because the inotify helper also runs from the
worker context.

Move the fork earlier just after parsing and validating the command line
arguments. In order to handle setup errors in the child, a pipe is
opened and the parents waits until the child writes a status byte to it.
If the byte is 0, the parent considers the child setup successful and
exits and the child carries on as a daemon. Notably, the child doesn't
reopen stderr to /dev/null until after this so that it can send error
messages there.

Fixes: #1941

Dan Nicholson 0fbfc0b207 lib/gpg: Add more specific OstreeGpgError codes
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.

Append a byte encoding the OSTree object type for each object in the

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.

Dan Nicholson 8ec7d6322f lib/commit: Fix object sizes metadata for multiple commits
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.

Simon McVittie 4a3cae5aba New upstream version 2019.6 2019-12-14 10:47:26 +00:00
Colin Walters 5af403be0c Support mounting /sysroot (and /boot) read-only
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.

potentially causing an unnecessary bootcsum bump.

Jonathan Lebon 74936f98d8 lib/pull: Tweak update_timeout logic again
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.)

Jonathan Lebon d4a186e80e lib/pull: Avoid calling destroy on unref'ed GSource
We're creating the timer source and then passing ownership to the

`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.

Colin Walters c61234a428 bootloader: Add a zipl bootloader backend
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.

Javier Martinez Canillas 985a141002 grub2: Exit gracefully if the configuration has BLS enabled
Since Fedora 30 grub2 has support to populate its menu entries from the
BootLoaderSpec fragments in /boot/loader/entries, so there's no need to
generate menu entries anymore using the /etc/grub.d/15_ostree script.

But since ostree doesn't update the bootloader, it may be that the grub2
installed is an old one that doesn't have BLS support.

For new installs, GRUB_ENABLE_BLSCFG=true is set in /etc/default/grub to
tell the /etc/grub.d/10_linux script if a blscfg command has to be added
to the generated grub2 config file.

So check if BLS is enabled in /etc/default/grub and only add the entries
if that's not the case. Otherwise the menu entries will be duplicated.

The approach has the drawback that if a user sets GRUB_ENABLE_BLSCFG=true
in /etc/default/grub without updating grub2, they will get an empty menu.
Since there won't be any entries created by the 30_ostree script and the
blscfg command won't work on the older grub2.

Unfortunately there is no way to know if the installed grub2 already has
BLS support or not.

Jonathan Lebon 88182635ab boot/finalize-staged: Run after systemd-journal-flush.service
In Fedora 31, `systemd-journal-flush.service` uses a new
`--smart-relinquish-var` switch which fixes the
`umount: /var: target is busy` bug by telling journald to stop logging
to `/var` and back to `/run` again during shutdown.

This interacted with `ostree-finalize-staged.service` in a tricky way:
since we weren't strongly ordered against it, when we happened to
finalize after `/var` is relinquished, we never persisted the output
from that service to disk. This then threw off `rpm-ostree status` when
trying to find the completion message to know that finalization went
well.

Just fix this by adding an explicit `After=` on that unit. That way we
shut down *before* `systemd-journal-flush.service` (the `/var`
relinquish bit happens in its `ExecStop=`).

Jason Wessel b709c3c67b fsck: Implement a partial commit reason bitmask
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.

Dan Nicholson e49060c207 lib/gpg: Use g_spawn_sync to kill gpg-agent
For reasons I don't understand, GSubprocess doesn't play nice with KDE's
plasmashell. I assume this has something to do with the GSubprocess
using the glib worker thread while plasmashell uses the glib main
loop. Instead, just use g_spawn_sync to fork and wait in the current
thread.

Dan Nicholson d14472a7f0 lib/gpg: Don't kill gpg-agent on newer gnupg
GnuPG 2.1.17 contains a bug fix so that `gpg-agent` is killed when the
entire GPG home directory is deleted[1]. If the host's GnuPG is new
enough, then we don't need to bother calling `gpg-connect-agent` to kill
the agent since it will be cleaned up on its own.

Get the GnuPG version from the GPGME OpenPGP engine info and parse it to
see if it matches this criteria.

Dan Nicholson 522d31b2d4 lib/gpg: Only show gpg-connect-agent stderr on failures
When listing GPG keys, the temporary GPG homedir will be constructed by
simply copying the remote's trusted keys to the pubring.gpg file. In
that case, no GPG operations spawning gpg-agent will be run. When
gpg-connect-agent is run to cleanup the homedir, it will helpfully print
on stderr that it's starting gpg-agent like so:

gpg-connect-agent: no running gpg-agent - starting '/usr/bin/gpg-agent'
gpg-connect-agent: waiting for the agent to come up ... (5s)
gpg-connect-agent: connection to agent established

Send gpg-connect-agent's stderr to a pipe and only send it to the
application's stderr if an error was encountered.

Javier Martinez Canillas d42f970ed3 lib/bootconfig-parser: Always include deployment index in BLS title
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
Using config file '/etc/zipl.conf'
Using BLS config file '/boot/loader/entries/ostree-3-testos.conf'
Using BLS config file '/boot/loader/entries/ostree-2-testos.conf'
Using BLS config file '/boot/loader/entries/ostree-1-testos.conf'
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)
ostree-2-testos.conf:title TestOS 42 20190902.0 (ostree:1)
ostree-3-testos.conf:title TestOS 42 20190902.0 (ostree:0)

Javier Martinez Canillas 2ca2b88f51 lib/bootconfig-parser: Write BLS fragment fields in a deterministic order
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:

Javier Martinez Canillas f82f825fed lib/bootconfig-parser: Remove support to preserve comments in BLS files
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.

Colin Walters 93999d337e sysroot: Add a clearer error if /boot/loader isn't found
I've seen people confused by this error in the case where
`/boot` isn't mounted or the BLS fragments were deleted, etc.
If you understand ostree deeply it's clear but, let's do
better here and a direct error message for the case where
we can't find `/boot/loader` which is the majority of these.

The other case could happen if e.g. just the BLS fragment
for the booted deployment was deleted; let's reword that
one a bit too.

Daniel Drake 99d56215e6 lib/deploy: handle FIFREEZE ENOSYS failure
When running under qemu, unimplemented ioctls such as FIFREEZE
return ENOSYS, and this causes the deployment to fail.

Catch this and handle it like EOPNOTSUPP.

Jonathan Lebon 0c48769de3 bin: Better handle --
We would stop passing through `--` and args after it to the underlying
command in `ostree_run`. This made it impossible to use `--` to tell the
parser that following args starting with `-` really are positional.

AFAICT, that logic for `--` here came from a time when we parse options
manually in a big loop, in which case breaking out made sense (see
97558276e4).

There's an extra step here, which is that glib by default leaves the
`--` in the list of args, so we need to take care to remove it from the
list after parsing.
