These are built from the same sources as the regular binaries, so we
end up with the same sources multiple times in the compilation database
but with different command line arguments, which trips up tooling that
uses the compilation database. Let's not define the standalone targets if
the option is not enabled to avoid this problem.
If --generate-fstab=PATH is used, there is the possibility that the
fstab file already exists, making systemd-repart fail.
This commit will add a new --append-fstab= parameter, that will read
the file and merge it with the new generated content. Using the
comments, the command can separate the automatic-generated section from
the user-provided section, allowing for the next append the replacement
only of the automatic-generated section, keeping the user one.

Let's always make sure the temporary file returned by fopen_tmpfile()
and friends is removed on failure (via _cleanup_). Conversely, make sure
that once the file is renamed into its final place, we no longer try to
remove the temporary file (since it's not going to exist anymore).
This commit cleans up the includes for all the small tools across
the tree.
A few cases of returning EXIT_SUCCESS are replaced with returning
0 to avoid including <stdlib.h>.
Split out of #37344.
Let's move some more implementation logic into functions. We keep
the logic that requires the macro in the macro and move the rest into
functions.
While we're at it, let's also make the parameter declarations of
all the string table macros less clausthrophobic.
Let's automatically generate validatefs xattrs by default, that encode
the intended use of partitions.
This defaults to on, since the structure of repart definition files
tells us enough on use for this to be safe. There's an option however,
to turn this off.
Admittedly, some of our glyphs _are_ special, e.g. "O=" for SPECIAL_GLYPH_TOUCH ;)
But we don't need this in the name. The very long names make some invocations
very wordy, e.g. special_glyph(SPECIAL_GLYPH_SLIGHTLY_UNHAPPY_SMILEY).
Also, I want to add GLYPH_SPACE, which is not special at all.
To resolve conflict with sys/mount.h and linux/mount.h or linux/fs.h.
The conflict between sys/mount.h and linux/mount.h is resolved in
glibc-2.37 (774058d72942249f71d74e7f2b639f77184160a6), but our baseline
is still glibc-2.31. Also, even with the version or newer, still
sys/mount.h conflicts with linux/fs.h, which is included by
linux/btrfs.h.
This introduces our own implementation of sys/mount.h, that can be
simultaneously included with linux/mount.h and linux/fs.h. This also
imports linux/fs.h, linux/mount.h, and several other dependent headers.
The introduced sys/mount.h header itself may not be enough simple, but
by using the header, we can drop most of workarounds in other source files.
Add --join-signature=hash:sig - when a verity signature partition
has been deferred in a previous run, this allows attaching a signature
that was created offline, for example on a build system like OBS where
the private key is not available to the build process.
Can be specified multiple times, the right partition to act upon will
be selected by matching the data+verity partitions UUIDs with the
provided roothash(es)
For many reasons, we might not actually sign a verity signature
partition, even if ope is specified in the partition definition files.
It might already exist, it might be deferred, it might be excluded, ...
Since we cannot check if partition already exists when reading the
configuration, let's delay the check for whether a certificate and
key have been provided until we're actually about to sign a roothash.
We're getting EOVERFLOW when reading file attributes trying to get
mkosi running in a docker container (don't ask). I have a suspicion
this is coming from fuse-overlayfs. Anyway, since the file attributes
stuff is supposed to be purely optional, let's not fail when we can't
read file attributes for whatever reason.
PCR 7 covers the SecureBoot policy, in particular "dbx", i.e. the
denylist of bad actors. That list is pretty much as frequently updated
as firmware these days (as fwupd took over automatic updating). This
means literal PCR 7 policies are problematic: they likely break soon,
and are as brittle as any other literal PCR policies.
hence, pick safer defaults, i.e. exclude PCR 7 from the default mask.
This means the mask is now empty.
Generally, people should really switch to signed PCR policies covering
PCR 11, in combination with systemd-pcrlock for the other PCRs.
This new field allows specification of an fd on which the password
prompt logic will look for POLLHUP events for, and if seen will abort
the query.
The usecase for this is that when we query for a pw on behalf of a
Varlink client we can abort the query automatically if the client dies.
- Let's check if the minimum size we got is larger than the configured
maximum partition size and fail early if it is.
- Let's make sure for writable filesystems that we make the minimal
filesystem at least as large as the minimum partition size, to allow
creating minimal filesystems with a minimum size.
