Necessary for crypto_random_bytes(), which is used in the branch that
HAVE_CRYPT_GENSALT_RA is false. Unfortunately, our CIs tested only the
other branch.
Not sure why the test failed, but maybe the test environment is too
slow? Even this does not fix the failure, by enabling debugging logs,
this hopefully provides more useful information for debugging.
For issue #37685.
This introduce bus_error_is_connection(), and use it where applicable.
Then, this makes connection errors in acquiring invocation ID by
systemd-run handled gracefully, like we already do other places.
Fixes#37675.
Device ID uses device directory name as is, hence may contain '!', but
sd_device_new_from_subsystem_sysname() expects that the input is sysname.
So, we need to replace '!' with '/'.

Fixes#37711.
While the `port_vlan_id` field was already present in the
`sd_lldp_neighbor`, it wasn't currently parsed from the LLDP packet.
Added support for that as well as a small parsing test.
Closes#28354.
Both ENOEXEC and ESRCH is a kind of error that indicate successful
lookup. ENOEXEC means the server found an entry but it does not
pass filter. ESRCH means the server could not find an entry.
Hence, ENOEXEC should have more information, and should be propagated to
the caller.

For gcc, flex-array-member-not-at-end was enabled by the commit,
but the option for clang with the same effect was still disabled.
Let's reenable it.
Prompted by #37497.
Note, the preceding fields have size that is a multiple of 8 bytes,
so the end of `.size` is aligned, thus
`offsetof(ObjectHeader, payload) == sizeof(ObjectHeader)`.
The struct ObjectHeader is embedded in real object structs.
Hence, the existence of the flex array in ObjectHeader violates the
requirement that flex array must be at the end of struct.
When bootctl is called by an unprivileged user, then previously we got
```
Failed to read "/boot/EFI/systemd": Permission denied
Failed to open '/boot//loader/loader.conf': Permission denied
```
Now, with this patch, we get
```
Failed to read "/boot/EFI/systemd": Permission denied
Failed to open '/boot/loader/loader.conf': Permission denied
```
With c960ca2be1, logind triggers uevents
for devices with uaccess tag, and waits for the events being processed
by udevd.
However, logind received not all triggered events, and might lose some
events. That causes session and user state file not updated, and many
desktop environment application handled the session and user were inactive.
This introduces one more device monitor instance which monitor events
for devices with 'uaccess' tag. Hence, all triggered events will be
recieved by logind, and session and user state file will be updated.
Follow-up for c960ca2be1.
Fixes#37579.
When starting unit A, a dependent unit B may be loaded if it is not
loaded yet, and the dependencies in unit A may be updated.
As Hashmap does not allow a new entry to be added in a loop, we need to
restart loop in such case.
Fixes a bug introduced by cda667722c.
Fixes#36031.
When unit_load() failed for some reasons, previously we overrided the
load state with UNIT_NOT_FOUND, but we did not update the
Unit.fragment_not_found_timestamp_hash. So, the unit may be loaded
multiple times when the unit is in a dependency list of another unit,
as manager_unit_cache_should_retry_load() will be true again even on
next call.
Let's not override the unit state set by unit_load().
Note, after unit_load(), the unit state should not be UNIT_STUB.
Let's also add the assertion about that.
This change is important when combined with the next commit, as with the
next commit we will restart the FOREACH_UNIT_DEPENDENCY() loop if an unit
is reloaded, hence overriding load state with UNIT_NOT_FOUND may cause
infinit loop.
The function manager_unit_cache_should_retry_load() reutrns true only
when the unit state is UNIT_NOT_FOUND. Hence, it is not necessary to
call bus_unit_validate_load_state() before checking
manager_unit_cache_should_retry_load().
We have already exposed device ID in the output of device ID in J
fields. Also sd_device_get_device_id() and sd_device_new_from_device_id()
are already public. Hence, making udevadm accept device IDs may be
useful.
With this change, as we save several data in /run/udev with device ID,
we can call udevadm something like the following:
```
udevadm info $(ls /run/udev/tags/uaccess)
```
Then, we can show all devices that has uaccess tag.
This renames e.g. struct bus_body_part -> BusMessageBodyPart to
follow our usual coding style. Also, several struct and enum
declarations are moved to relevant headers.
Also, this introduces bus-forward.h.
Even if -fno-finite-math-only is specified, -ffinite-math-only,
-ffast-math, or -Ofast may be also specified after that. In that case,
-fno-finite-math-only has no effect, and test-json will fail.
Replaces #37603.
This fixes the following warning:
```
/tmp/systemd/test/test-network/systemd-networkd-tests.py:5107: SyntaxWarning: invalid escape sequence '\.'
self.assertRegex(output, 'inet 10\.234\.77\.111/32.*dummy98')
```

If master ifindex is non-zero, then the carrier state and operational
state of the interface may be the enslaved state.
As the operational state is saved in link state file, and read by
wait-online, we need to update the state file when the master ifindex is
changed.
When an interface leaved from the master interface, then reading
IFLA_MASTER attribute causes ENODATA. When the interface was previously
enslaved to another interface, we need to remove reference to the
interface from the previous master interface.
This is especially important when
```
ip link set dev eth0 nomaster
```
is called.
Fixes a bug introduced by 0d411b7f8f (v249).
Fixes#37629.
Re-introduce the check dropped by
ec3c5cfac7,
ad446c8ceb.
For some reasons, if we are running on LXC, even if bpf_program_supported()
returned true, but bpf_program_load_kernel() failed:
```
Attaching device control BPF program to cgroup /system.slice/test-bpf-devices-875b406d56ac7bc3.scope/186c411f6e991777 failed: Operation not permitted

```
Add support for the hardware family, SKU (Stock-Keeping Unit) and
version. The values are read from the file /etc/machine-info or DMI as
fallback.
The entries are useful to provide an unified interface to collect detail
hardware information. The /etc/machine-info entries enable embedded
devices without UEFI support to provide the information via a common
interface.
Fixes: #31134
This also makes initrd-cleanup.service explicitly start
initrd-switch-root.service with replace-irreversibly mode, to avoid
systemd-udevd.service being triggered by kernel events and the start
job of initrd-switch-root.service being cancelled.
