This let's systemd-repart respect the `SOURCE_DATE_EPOCH` environment
variable when creating directories in the local tree through `CopyFiles`
or `MakeDirectories`.
To do this, we pass a timestamp `ts` to `mkdir_p_root`, which it will
use to fix up `mtime` and `atime` of the directory it creates as
well as the `mtime` of the directory it creates the other directory *in*,
as the `mtime` of the latter is modified when creating a directory in it.
For the same reason, it also needs to fixup the `mtime` of the upper
directory when copying a file into it through `CopyFiles`.
If `SOURCE_DATE_EPOCH`, times are left as is. (`UTIME_OMIT`)
- drop unnecessary SYNTHETIC_ERRNO() when the logger does not propagate
error code,
- drop unnecessary '%m' in error message when the error code is
specified with SYNTHETIC_ERRNO(),
- add missing full stop at the end of log message,
- use RET_GATHER(),
- add missing ", ignoring.",
- upeercase the first letter, etc., etc...
We so far just print a short log message that is not very useful, let's
add some recognizable error codes, and output better log messages if we
can't get TPM stuff to work.
Fixes: #31925
gcrypt is used only for journal sealing operations in libsystemd, so it
can be made into a dlopen dependency that is used only on demand. This
allows to reduce the footprint of libsystemd in the most common cases.
Keep systemd-pull and systemd-resolved with normal linking, as they are
executables, and usually built with OpenSSL support anyway.
It turns out it's mostly PKCS11 that supports the URI format,
and other engines just take files. For example the tpm2-tss-openssl
engine just takes a sealed private key file path as the key input,
and the engine needs to be specified separately.
Add --private-key-source=file|engine:foo|provider:bar to
manually specify how to use the private key parameter.

let's make userspace verity signature checking optional. This adds a
dissection flag to enable the logic and patches through all our users to
enable it by default, thus effectively not changing anything from the
status quo ante. However, know we have a knob to turn this off in
certain scenarios.
These can be used along with two new settings MountPoint= and
EncryptedVolume= to write fstab and crypttab entries to the given
paths respectively in the root directory that repart is operating on.
This is useful to cover scenarios that aren't covered by the
Discoverable Partitions Spec. For example when one wants to mount
/home as a separate btrfs subvolume. Because multiple btrfs subvolumes
can be mounted from the same partition, we allow specifying MountPoint=
multiple times to add multiple entries for the same partition.
The provider API which is new requires providers, which are not
widely available and don't work very well yet, so also use a
fallback with the legacy engine API.
If we are told to start from scratch we shouldn't look into the old
image to determine sector size. Looking there is confusing at best, but
plain wrong in many other cases.
Properly skip over dropped partitions and make sure they don't affect
the final graphical output (for example by leaving empty "spaces" where
their definition file name would otherwise be).
Resolves: #30742
This function is just a wrapper around the BLKGETSIZE64. Which is a
pretty simple ioctl. The only reason to wrap it, is that the headers we
need to call it are a bit messy (as "linux/fs.h" is incompatible with
certain glibc headers). Hence add the simple helper that wraps it and
allows us to do the header mess needed in one file only.
It's also nicely symmetric to blockdev_get_sector_size().
It doesn't really make sense to go looking for these inside the
given root directory. While we should resolve specifiers and such
based on the given root directory, let's look up the image definitions
on the host system as there's a good chance they're coupled to the
repart version we're using so there's all kinds of chances for problems
if we use the definitions from the image we're building instead of those
from the host.
The mkfs binary might unlink the path we give it and replace it with
a new file so let's make sure that our fd points to any new file rather
than the old deleted file.
Specifically this fixes erofs partition generation.
Otherwise, repart won't calculate the minimal size of the partition
automatically and things will fail once the partitions exceed the
minimal partition size (10M).
The warning is about unused variable "flags":
```
../src/partition/repart.c: In function ‘partition_encrypt’:
../src/partition/repart.c:3690:19: warning: unused variable ‘flags’ [-Wunused-variable]
3690 | TPM2Flags flags = 0;
| ^~~~~
```
Move the flags variable into the scope where it is actually used, which happens
to be inside the HAVE_TPM2 block.
At first I thought when using --copy-from= that it was copying in my
whole disk into a partition instead of just a partition into a
partition.
Let's make the log message clearer and say that we copy starting from an
offset.
Currently, we round minimum sizes up and maximum size down, whereas
it should be the opposite as the current approach means that if the
same size is used for min and max, the min size will end up bigger
than the max size after rounding.
