EFI_LOADER_VARIABLE() already applies to the stringify to construct the
path of EFI variable in efivars, so it is wrong to enclose the name of
EFI variable with the quotes. Otherwise, the following errors are
reported.

This is useful to make the dissection logic at boot a bit safer, as we
can reference device nodes by diskseq.
This locks down dissection a bit, since it makes it harder to swap out
the backing device between the time we dissected and validated it, until
we actually mounted it.
This is not complete though, as /bin/mount would have to verify the
diskseq after opening the diskseq symlink again.

This allows FIDO2 users to wipe out password slots and still be able to
enroll new key slots via systemd-cryptenroll. Note that when the user
wants to both unlock with a FIDO2 token and enroll a new FIDO2 token,
they cannot be set to automatic discovery. This is to safeguard against
confusion, because there will be multiple tokens connected to the system
when doing so -- and we require users to explicitly confirm which one to
use for unlocking and which one to use for enrollment.
Addresses #20230 for the FIDO2 case.
`acquire_fido2_key_auto()` will not be used in PLAIN mode, and
parameters such as the salt will be acquired from the LUKS header.
Parameters intended for PLAIN mode are useless in
`acquire_fido2_key_auto()`.
llvm-objcopy works on stubs built for foreign architectures whereas
objcopy doesn't so let's prefer using llvm-objcopy instead of objcopy.
llvm-objcopy automatically sets the virtual address and doesn't provide
an option to set it manually so we only add --change-section-vma when
using objcopy
The default section flags differ between llvm-objcopy and objcopy
so we add a default for the section flags so we make sure all sections
are read-only data unless specified otherwise.
When we dissect images automatically, let's be a bit more conservative
with the file system types we are willing to mount: only mount common
file systems automatically.
Explicit mounts requested by admins should always be OK, but when we do
automatic mounts, let's not permit barely maintained, possibly legacy
file systems.
The list for now covers the four common writable and two common
read-only file systems. Sooner or later we might want to add more to the
list.
Also, it might make sense to eventually make this configurable via the
image dissection policy logic.
Previously, when neither '--any' nor '--interface' options specified,
at least one of the interfaces must be in configured state.
This patch makes wait-online exit with success even if all interfaces
are in unmanaged state.
This may break backward compatibility in a rare situation. But in most
cases, this typically not change anything, as at least one interface
is managed by networkd.service when it is enabled.
This is mostly for making wait-online gracefully handle the case that
networkd.service and wait-online.service are enabled by mistake. In such
situation, all interfaces are typically not managed.
Fixes#25813.
This changes the definition from enpty_to_null() so that we are still
typesafe (i.e. only accept strings) but do not drop (or add) any const
to the returned string that wasn't also on the input.

CVE-2022-4415: systemd: coredump not respecting fs.suid_dumpable kernel setting
Affects systemd >= 247 with libacl support enabled.
This is a merge of https://github.com/systemd/systemd-security/pull/12/.
I'm doing the merge locally because github doesn't support merging directly
from systemd/systemd-security to systemd/systemd.
It's much nicer for the user if we fail early instead of doing partial
processing if we cannot read some input. We can't do those checks immediately
from argparse.Parser.parse_args(), because we want to fully process the
commandline first. In particular, even with invalid args, if --help is
specified somewhere, we want to handle that. Thus, we need to delay the checks
after argparse.Parser.parse_args() returns.
Ukify didn't have type annotations on functions, but it probably should.
Jörg's suggested correction included them and we might just as well start here.
Previously 'systemctl edit' would only operate on
'override.conf', but users may need more than that.
Thus the new option '--drop-in' is added to allow
users to specify the drop-in file name.
Closes#25767
The autodetection code is supposed to throw ValueError when it
cannot figure out the version so that we fall back to the next method.
With the patch:
Kernel version not specified, starting autodetection 😖.
Real-Mode Kernel Header magic not found
+ readelf --notes vmlinuz/arm64/vmlinuz-6.0.9-300.fc37.aarch64

Process renaming happens very seldomly so we are able to afford proper
permission check, i.e. actually check for CAP_SYS_RESOURCE capability
instead of euid.
