These three functions are currently only used by sbsign, which requires
OpenSSL. Moreover, pe_hash() and uki_hash() anyway do not work if
OpenSSL is disabled. Let's only declare them when OpenSSL support is
enabled.
The functions crypt_set_metadata_size() and friends are supported since
libcryptsetup-2.0.
This also merges checks for functions used for supporting libcryptsetup
plugins with others.
Moreover, check existence of one more function (crypt_logf) that is used in
libcryptsetup plugins.
Before aa47d8ade1, we took an exclusive lock
for the whole block device, but with the commit, a shared lock is taken.
That causes, during we requesting the kernel to reread partition table,
udev workers can process the block device or its partitions.
Let's make udev workers not process block devices during rereading
partition table again.
Follow-up for aa47d8ade1.
All other cases, settings on different interfaces are completely
independent. But IPMasquerade=yes on an interface enables the global
IPv6Forwarding= setting, and hence affects other interfaces.
Let's log about that.
Prompted by https://github.com/systemd/systemd/issues/39304#issuecomment-3430382233.
As 'systemctl stop' is called with --no-block, previously systemd-resolved
might not be stopped when 'resolvectl' is called, and the DBus connection
might be closed during the call:
```
TEST-07-PID1.sh[5643]: + systemctl stop --no-block systemd-resolved.service
TEST-07-PID1.sh[5643]: + resolvectl
TEST-07-PID1.sh[5732]: Failed to get global data: Remote peer disconnected
```

So even if a <term> section contains newlines, we get a reasonable
anchor link to it.

The reverts are not strictly necessary here (as already pointed out in
https://github.com/systemd/systemd/pull/39154#issuecomment-3360118164)
but they were helpful in checking if the fix works as expected. I can
drop them if needed.
Otherwise, we may not get stacktrace of the crashed process when it is
in running a mount namespace, especially when it is in a portable
service or service that uses RootImage=/RootDirectory=.
- Renames Context to CoredumpContext.
- Renames enum meta_argv_t to MetadataField, and use the correct type at
several pleaces, especially in loop.
- Parses argv (when invoked as kernel helper or with '--backtrace') or
iov (when invoked through socket) and store values in the context.
Previously we use the passed string as is, but let's make them in a
type safe way.
- Stores received or built iovw in the context. Also store input fd and
mountfs fd in the context.
- Introduces coredump_context_is_pid1() and _is_journald() helper
functions.
- Adds COREDUMP_PIDFDID= field when the kernel passed pidfd of the
crashed process.
No effective funtional change. Just refactoring.
When running as backtrace mode, it is not necessary to use kmsg, not
necessary to disable coredump from the command, and unexpectedly
passed file descriptors can be silently ignored.
- introduce CoredumpConfig object that stores all configuration
parameters parsed from coredump.conf,
- use gperf to generate conf parser table,
- parse coredump.conf only when necessary: when systemd-coredump is
invoked as kernel helper or by socket actiavation.
Previously, we limit the length of process name by 8.
This relax the restriction then at least process comm or
program_invocation_name contains the untrucated process name.
Closes#38367.
As the modified service requires about ~10 seconds for stopping, the
service never hit the start limit even if we tried to restart the
service more than 5 times.
This also checks that the service is actually triggered by dbus method
call.

capability_get() is a wrapper of capget() syscall and converts its
result to CapabilityQuintet.
This also introduce have_inheritable_cap(), which is similar to
have_effective_cap(). It is currently unused, but will be used later.
