When running `updatectl update` since f0b2ea63, Install() was called
with the version resolved by Acquire() rather than the originally
requested (empty) version, causing the stricter update-to-version polkit
action to be used instead of the update polkit action.
`updatectl enable --now` systematically fails because the update phase find
resources that are not pending. So instead we should ignore them.
Fixes#41254
Ensure bogus inputs are cleanly rejected. These are privileged
interfaces so in practice it's not a problem.

Add an optional field that can be used to store a user's birth date.
userdb already stores personal metadata (`emailAddress`, `realName`,
`location`) so `birthDate` is a natural fit.
Move the YYYY-MM-DD date parsing and validation logic from
sysupdate-resource.c into a shared parse_calendar_date() function
in time-util, so it can be reused by other subsystems.
We often have a pattern where the same verb function is used for
multiple actions. This leads to an antipattern where we figure out what
action needs to be taken from argv[0] multiple times: often once in
parse_argv() to figure out what options are allowed, then once again
implicitly in dispatch_verb(), and then again in the action verb itself.
Let's allow passing a parameter into the verb to simplify this.
This matches a pattern we have in conf-parser.h, where we have both
void *userdata (more global) and void *data (per-config item). Here,
I opted for uintptr_t userdata. It seems that most of the time we'll
want to just pass an enum value. This works OK with no casts. I also
tried a void* and union. In both cases, much more boilerplate is needed:
either a cast or a macro to help avoid compiler warnings. uintptr_t
seems generic enough to cover foreseeable usecases with no fuss.
This is a noop refactoring. See next commit for an example.
These functions take so many return paramaters, and in many of our cases
we don't actually needt them. Hence introduce _full() flavours of the
funcs, and hide the params by default.
Now that it’s been replaced by `Acquire()` and `Install()`, there’s no
need to expose it as a separate method. Wrappers around `sysupdated` can
still expose an ‘update’ convenience verb by calling those two methods.

Rather than calling `Update()`. This should allow us to eventually drop
`Update()`.
This should just be an internal change, and should not result in any
user-visible changes to the behaviour of `updatectl update`.

These mirror the `sysupdate acquire` and `sysupdate update --offline`
verbs, which are themselves a split of `sysupdate update` into
downloading and installing stages.
The existing `sysupdated` `Update()` method is kept for now, for
convenience. It might be dropped in future.

We don't want to vacuum anything if we're just going to fail just
afterwards because a GPT partition label exceeds the maximum size
so let's compute the temporary paths for all transfers before we do
any vacuuming or acquiring.
These expose the two parts of ‘update’, so that update sets can be
acquired (downloaded) and installed (applied) in separate actions at
different times. For example, this could allow a load of update sets to
be acquired when online, and later applied when offline.

An ‘acquire’ (download) part, and an ‘install’ (apply) part.
Following commits will expose these as separate verbs and D-Bus methods,
but this commit is the one which rearranges the internals.
If doing an ‘install’, a mirror version of the ‘acquire’ has to happen
first to make sure the transfer’s internal state is correct.
‘Acquire’ can require an internet connection, but ‘install’ will always
work with `--offline` specified.

This commit adds the flags and some basic formatting/printing of them.
Following commits will integrate them into the update/acquire/install
logic.
`UPDATE_PARTIAL` is set if any of the instances in the `UpdateSet` are
partial, i.e. have been partially downloaded.
`UPDATE_PENDING` is set if any of the instances in the `UpdateSet` are
pending, i.e. have been acquired (downloaded) but not yet installed.

Modify the vacuum implementation to preferentially vacuum partial or
pending transfers first (unless protected) as they are meant to be
fairly transitory, and ones which are hanging around have probably been
forgotten about and/or are out of date.

Instead of using a random temporary path for file transfers, use a
predictable one which indicates whether the transfer is partially
complete or pending installation. Similarly for partitions.
This is another step towards being able to split the ‘update’ step into
‘acquire’ and ‘install’.

If we allow target instances to be partial or pending, we can build on
top of this to allow updates to be split into two phases: ‘acquire’ (which
takes an available source instance and copies it (temporarily partial) to
a pending target instance; and ‘install’ (which takes a pending target
instance and installs it as an installed target instance).
This commit introduces a file/directory and partition prefix naming
scheme to identify partial and pending instances.

get_block_device_harder_fd() currently only traverses one level of
device mapper stacking when looking for the underlying block device.
This causes issues with nested DM setups like dm-crypt on top of
dm-integrity, where we don't traverse enough to get the actual physical
device.
Fix this by iterating through all DM layers until we reach a device with
no underlying device. And while we're at it also make cgroups use the
same logic.
Fixes: #40419
Let's make sure we can safely load configuration files based on a root
fd, including XAT_FDROOT.
(While we are at it, always pass path to root fs before fd to root fs,
following our recently updated CODING_STYLE)
Originating device lookups currently use separate entry points and
callers must decide between the single-step helper and manual looping.
Add a recursive flag to block_device_get_originating() and
block_get_originating(), and update callers to pass an explicit value.
In order to make "freeze" attacks against the update logic harder let's
add the ability to encode a "Best Before" date into SHA256SUMS directory
listings: if the current time is already beyond that time, we'll ignore
the SHA256SUMS as "stale" and fail the upgrade. Or in other words: the
freeze attack will now result in a client-side error eventually, instead
of success state.
The best before data is encoded in an optional pseudo-file listed in SHA256SUMS:
any file named BEST-BEFORE-YYYY-MM-DD.

After the mentioned commit, event_add_child_pidref() duplicates
the pidfd internally, hence the original pidfd would be leaked
with TAKE_PIDREF.
Let's introduce these for the following two reasons:
- Using them makes sure the parameter names match between declaration
and definition (if both use the corresponding macros).
- They make sure developers can't forget the _const_ and _pure_
attributes for the declarations.
This commit also includes some include sorting fixes
Now that sd-event doesn't insist on blocking
SIGCHLD anymore when watching for process exit,
let's stop blocking SIGCHLD tree-wide where not
required anymore.
In all cases, everything that we list in 'extract', we also list in
'sources'. We can simplify things by automatically appending the first
list to the second.
In the listings, move 'extract' key right below 'sources', since now
they are both "sources", just with slightly different meanings.
- Make sure forward headers have the iwyu pragma to always keep them
- Make sure we always include the daemon specific forward header
instead of shared-forward.h
- Remove shared-forward.h include where the daemon specific forward
header is already included
Let's not leak details from src/shared and src/libsystemd into
src/basic, even though you can't actually do anything useful with
just forward declarations from src/shared.
The sd-forward.h header is put in src/libsystemd/sd-common as we
don't have a directory for shared internal headers for libsystemd
yet.
Let's also rename forward.h to basic-forward.h to keep things
self-explanatory.
