mkdir_p() uses the specified access mode for all dirs that are missing,
hence if we call it on /run/systemd/nspawn/locking and
/run/systemd/nspawn/ doesn't exist yet, we#d create it 0700 here. But
that was never the intention, and all other code creating that dir sets
the mode to 0755. Fix this here to match the rest.
When using the `--image` or `-E` options, `arg_exclude_prefixes` is extended via
the `exclude_default_prefixes` function, which calls `strv_extend_strv`, adding
values using `strdup` that must be freed on exit.
Also changing `arg_include_prefixes` to use the same model, although there is no
leak here.
Deprecated IPTOS_LOWDELAY is ignored by most of today's
network equipment that only ever care about DSCP.
Use the DSCP found in other NTP implementations and set the appropiate
TCLASS for IPv6.
To get the CPUID with EAX=7, we need explicitly set 0 to ECX.

Leaf 07H output depends on the initial value in ECX.
If ECX contains an invalid sub leaf index, EAX/EBX/ECX/EDX return 0

Fixes#30822.
To me this is the last major basic functionality that couldn't be
configured via credentials: the network.
We do not invent any new format for this, but simply copy relevant creds
1:1 into /run/systemd/network/ to open up the full functionality of
networkd to VM hosts.
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
Otherwise, e.g. when we enumerate a bridge port first, then the bridge
main interface, then the port cannot be managed by the main interface.
Fixes#30682.
Since libfuzzer feeds a single fuzzing process with multiple inputs, we
might carry over arg_transport from a previous invocation, tripping over
the assert in acquire_bus():

Assertion 'transport != BUS_TRANSPORT_REMOTE || runtime_scope == RUNTIME_SCOPE_SYSTEM' failed at src/shared/bus-util.c:284, function bus_connect_transport(). Aborting.

The passed attribute type will be used later.
This also
- rename conf parsers,
- sort gperf entries by the attr type.
No functional change, just refactoring and preparation for later commits.
This also split config_parse_route_boolean() into two:
for GatewayOnline= and boolean route metrics.

On Linux only the "w" access bit is necessary to connect to an AF_UNIX
socket, hence let's only set that and nothing else, to limit exposure.
Just paranoia.
Previously, there was no way to override the log level for test and
test-builtin commands. Let's re-parse environment after setting the log
level to debug. Then, we can control the log level through environment
variable.
Let's operate on fds rather than paths. Make some tweaks to the logic on
top:
1. Mark the resulting dir as read-only after we are done.
2. Use the new inode_type_to_string() calls to determine the inode
names.
3. If an inode already exists, try to adjust the access mode, just in
case.
4. Use FOREACH_ARRAY()
This patch adds a new parameter to parse_ip_port_range, giving callers
the option to allow ranges to have their min be 0 instead of 1.
This is then used by parse_ip_ports_token, intern used by
parse_socket_bind_item to allow port 0 when restricting bind system
calls with SocketBindDeny / SocketBindAllow.
With this, users running server software written using the golang
standard library will be able to effectively sandbox their software,
albeit with a small loss in security protections by allowing the
process to bind on a random port in the
/proc/sys/net/ipv4/ip_local_port_range.
