This adds support for discovering and making use of properly tagged dm-verity
data integrity partitions. This extends both systemd-nspawn and systemd-dissect
with a new --root-hash= switch that takes the root hash to use for the root
partition, and is otherwise fully automatic.
Verity partitions are discovered automatically by GPT table type UUIDs, as
listed in
https://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec/
(which I updated prior to this change, to include new UUIDs for this purpose.
mkosi with https://github.com/systemd/mkosi/pull/39 applied may generate images
that carry the necessary integrity data. With that PR and this commit, the
following simply lines suffice to boot up an integrity-protected container image:
```
# mkdir test
# cd test
# mkosi --verity
# systemd-nspawn -i ./image.raw -bn
```
Note that mkosi writes the image file to "image.raw" next to a a file
"image.roothash" that contains the root hash. systemd-nspawn will look for that
file and use it if it exists, in case --root-hash= is not specified explicitly.
This adds support to the image dissector to deal with encrypted images (only
LUKS). Given that we now have a neatly isolated image dissector codebase, let's
add a new feature to it: support for automatically dealing with encrypted
images. This is then exposed in systemd-dissect and nspawn.
It's pretty basic: only support for passphrase-based encryption.
In order to ensure that "systemd-dissect --mount" results in mount points whose
backing LUKS DM devices are cleaned up automatically we use the DM_DEV_REMOVE
ioctl() directly on the device (in DM_DEFERRED_REMOVE mode). libgcryptsetup at
the moment doesn't provide a proper API for this. Thankfully, the ioctl() API
is pretty easy to use.
This adds a small tool that may be used to look into OS images, and mount them
to any place. This is mostly a friendlier version of test-dissect-image.c. I am
not sure this should really become a proper command of systemd, hence for now
do not install it into bindir, but simply libexecdir.
This tool is already pretty useful since you can mount image files with it,
honouring the various partitions correctly. I figure this is going to become
more interesting if the dissctor learns luks and verity support.
This adds a bus call GetImageOSRelease() to the Manager interface that
retrieves the /etc/os-release file of a machine image. It matches the existing
GetMachineOSRelease() call, however operates on a disk image rather than a
running container.
The backend for this call on .raw images is implemented via the generalized
image dissector, which makes this scheme relatively easy to implement.
This adds mkdtemp_malloc() that is a combination of mkdtemp() plus strdup(). It
initializes its return paremeter only if the temporary directory could be
created successfully, so that the parameter is exactly non-NULL when the
directory exists.
rmdir_and_free() and rmdir_and_freep() are also added, and the latter may be
used inside of _cleanup_ for such a directory string variable, to automatically
rmdir() the directory if it is non-NULL when the scope exits.
rmdir_and_free() is similar to the existing rm_rf_and_free() however, is only
removes a single directory and does not operate recursively.
Let's make use of the new internal API. This mostly doesn't change anything for
the caller, however, "systemd-nspawn --image=/dev/sda7" works now as the new
code can handle disk images with no partition tables, and make any detected
images directly the root.
This adds two new APIs to systemd:
- loop-util.h is a simple internal API for allocating, setting up and releasing
loopback block devices.
- dissect-image.h is an internal API for taking apart disk images and figuring
out what the purpose of each partition is.
Both APIs are basically refactored versions of similar code in nspawn. This
rework should permit us to reuse this in other places than just nspawn in the
future. Specifically: to implement RootImage= in the service image, similar to
RootDirectory=, but operating on a disk image; to unify the gpt-auto-discovery
generator code with the discovery logic in nspawn; to add new API to machined
for determining the OS version of a disk image (i.e. not just running
containers). This PR does not make any such changes however, it just provides
the new reworked API.
The reworked code is also slightly more powerful than the nspawn original one.
When pointing it to an image or block device with a naked file system (i.e. no
partition table) it will simply make it the root device.
Let's accept "µs" as alternative time unit for microseconds. We already accept
"us" and "usec" for them, lets extend on this and accept the proper scientific
unit specification too.
We will never output this as time unit, but it's fine to accept it, after all
we are pretty permissive with time units already.
When we are in link_enter_configured we assume that the
link->state should be LINK_STATE_SETTING_ROUTES but in some
situation it's LINK_STATlE_SETTING_ADDRESSES.
Just ignore the wrong state.
Also since the return value not used any where
make link_enter_configured return type void.
Fixes: #4746
Make sure to populate the cache in cache_space_refresh() at least once
otherwise it's possible that the system boots fast enough (and the journal
flush service is finished) before the invalidate cache timeout (30 us) has
expired.

Evidently this code path was never hit, because we'd crash with NameError.
The exception message also seems bogus. So just replace the whole thing
with the standard exception for invalid input.
It is possible to specify only one quote in udev rules, which is not
detected as an invalid quoting (" instead of "" for empty string).
Technically this doesn't lead to a bug, because the string ends in two
terminating nul characters at this position, but a user should still be
reminded that his configuration is invalid.
The code was trying to detect an empty key, but property lines always
start with a space, so the condition was wrong.
Now:
[/tmp/tmp.YWeKax4fMI/etc/udev/hwdb.d/10-bad.hwdb:14] Empty key in " =NO_NAME", ignoring
[/tmp/tmp.YWeKax4fMI/etc/udev/hwdb.d/10-bad.hwdb:15] Empty value in " NO_VALUE=", ignoring
Since syntax error are non-fatal, downgrade them to warnings.
Use log_syntax to have uniform formatting including the line number.
State machine states like DATA and MATCH are internal, user-facing
messages should use the names from hwdb(7): match, property, record.
Also change "key/value" to "key-value", since there's no alternative
here, both parts must be present.

squash! hwdb: improve syntax error messages
Because -e was set, we'd exit immediately when systemd-hwdb failed and the
captured error output was never printed. We want to test two things:
that 0 is returned, and that nothing is printed to stderr (to catch
syntax errors in the hwdb).
v2: stop capturing stderr to a variable
v3: capture stderr to a variable and test both error types separately
