Unify pn81H3 and cvrLenovoideapadD330-10IGM
D330-10IGM has been added due the fact that 81H3 and 81MD product name belongs to the same product version. So the fact is that now that we know 81MD has the same transformation matrix that the 81H3 we can just use the product version and get rid the product name.

If ":" was the last char in the string, we would call access() on ".../drivers/", which
would pass. It probably doesn't matter, but let's reject this anyway.
Not only we would duplicate unknown input on the stack, we would do it
over and over. So let's first check that the input has reasonable length,
but also allocate just one fixed size buffer.
The ID_FFADO environment variable comes from external FFADO project.
Now we have comprehensive and self-contained rules instead of it.
Let's remove it.
hwdb: ieee1394-unit-function: add entry for AV/C device with vendor unique command set
In IEC 61883-1:1998, we can see some values for AV/C device with vendor
unique command set in IEC 61883-1:1998. Current udev rule handles it
for video. However it brings an issue that the functions in AV/C device
are not distinguished just by the content of configuration ROM.
In former commit, hardware database was added to describe function type
of unit in the node, then udev rules are added to utilize the database.
However, we have an request to obsolete existent udev rules by putting
enough entries to the database. It should be done carefully.
This commit adds entry into hardware database just for backward
compatibility. The entry can match to some node and unit unexpectedly.
Therefore this commit modifies existent entries to invalidate the effect
from added entry.

hwdb: ieee1394-unit-function: remove entry for Cool Stream iSweet
IIDC specification describes configuration ROM without model field, thus
it's not possible to match any entry with vendor ID and model ID.
Current entry for Cool Stream iSweet can match any node and unit of
IIDC.
This commit removes the entry. I note that this model uses Texus
Instruments MC680-DCC as all-in-one chipset for video function in
IEEE 1394 bus.

hwdb: ieee1394-unit-function: add entries for Digital Everywhere FloppyDTV and FireDTV
Linux kernel has firedtv kernel module as driver for Digital Everywhere

hwdb: fix parser to execute test for ieee1394-unit-function with no argument
When given no arguments, hwdb parser script seeks test target files by
glob pattern. Although I added a new file for IEEE 1394 unit functions,
the file is excluded as test target due to the pattern.
This commit fixes it.

The function returns non-negative UnitNameFlags on success, and negative
errno on error. In the past we kept the return type as int because of those
negative return values. But nowadays _UNIT_NAME_INVALID == -EINVAL. And if
we tried to actually return something that doesn't fit in the return type,
the compiler would throw an error. By changing to the "real" return type,
we allow the debugger to use symbolic representation for the variables.
I think quoting is more useful than not quoting. Without, arguments with
whitespace cannot be split correctly.
Unlike in coredump, "normal" quoting is used in those two cases. This output is
mostly for informational purposes, so the more readable quoting seems apropriate.
Before we wouldn't use any quoting, making it impossible to figure how the
command line was split into arguments. We could use "normal" quotes, but this
has the disadvantage that the commandline *looks* like it could be pasted into
the terminal and executed, but this is not true: various non-printable
characters cannot be expressed in this quoting style. (This is not visible in
this example). Thus, "POSIX quotes" are used, which should allow any command
line to be expressed acurrately and pasted directly into a shell prompt to
reexecute.
I wonder if we should another field in the coredump entry that simply shows the
original cmdline with embedded NULs, in the original /proc/*/cmdline
format. This would allow clients to format the data as they see fit. But I
think we'd want to keep the serialized form anyway, for backwards compatibility.
basic/process-util: add mode where posix shell escape is used for quoting
The new flag is not used, except in tests, so no functional change yet.
This way, the command as shown can be copied-and-pasted into the shell
in more cases. For simple cases, shell quoting with "" is enough. But
$'' is needed when there are control characters in the command.
Significant time was spent in the getpid() measurement code, which is not very
important. So let's optimize this a bit by running the slower version less
times, and only running both tests a lesser amount of times unless slow tests
are enabled.
This gives the better accuracy then before in slow mode, and still reasonable
accuracy in fast mode without a noticable slowdown.
test-process-util: add more debug logging but hide most of it by default
It makes little sense to always print the stuff that is fully deterministic
and verified by asserts. It can be opted-in with $SYSTEMD_LOG_LEVEL when
developing the tests or debugging a failure.
Since the new functionality is controlled by an option, this causes no change
in output yet, except tests.
The login in the old branch of !(flags & PROCESS_CMDLINE_QUOTE) is essentially
unmodified. But there is an important difference in behaviour: instead of
unconditionally reading the whole virtual file, we now read only 'max_columns'
bytes. This makes out code to write process lists quite a bit more efficient
when there are processes with long command lines.
basic/escape: allow truncation mode where "…" is always appended
So far we would append "…" or "..." when the string was wider than the specified
output width. But let's add a mode where the caller knows that the string being
passed is already truncated.
The condition for jumping back in utf8_escape_non_printable_full() was
off-by-one. But we only jumped to that label after doing a check with a
stronger condition, so I think it didn't matter. Now it matters because we'd
output the forced ellipsis one column too early.
basic/escape: escape control characters, but not utf-8, in shell quoting
The comment in the code said that so far this didn't matter, but I want to use
shell quoting in more places where this will make a difference. So control
characters are now escaped. Normal utf-8 characters are passed through, it
is 2021 after all and pretty much everyone is (or should be) using utf-8.
While touching the code, change 'char *r' → 'char *buf', in line with modern
style.
basic/escape: always escape newlines in shell_escape()
shell_escape() is mostly used for mount paths and similar, where we assume
no newlines are present in the string. But if any were ever present, we
should escape them. So let's simplify the code by making this unconditional.
"systemd-testsuite" gets in the way when grepping for "testsuite-*.sh".
Also, the name doesn't matter for anything, so let's just use something
very short to save space.

basic/unit-file: fix detection of instance aliases
We had the following scenario:
under /etc/systemd/system/
- foo@.service
- bar@tty12.service → foo@tty12.service
- multi-user.target.wants/foo@tty12.service
Existing code did not "know" that foo@tty12.service has alias bar@tty12.service:
$ systemctl show -P Names foo@tty12.service
foo@tty12.service
Since multi-user.target is always loaded, we would load foo@tty12.service.
When trying to load bar@tty12.service, it would (correctly) detect that
bar@tty12.service is an alias for foo@tty12.service, and try to merge the
bar@tty12.service unit into the foo@tty12.service. This would fail, because
foo@tty12.service was already loaded, and only about-to-be-loaded units can
be merged.
With the patch we consider bar@tty12.service an alias of foo@tty12.service
immediately, so the issue does not occur:
$ systemctl show -P Names foo@tty12.service
foo@tty12.service bar@tty12.service
Fixes #19409.
This turned in a bigger rewrite. The logic add "the main name and all aliases"
was implemented twice, slightly different in both cases. I split that part out
to a new function. The result about the same length, but hopefully a bit easier
to read.
Logging output is also improved a bit. Some left-over debug logs have been
removed or cleaned up.
This is a fairly big change, but (with the addition in the following commit),
we have pretty good coverage of this logic.
basic/io-util: invert return value from IOVEC_INCREMENT()
We would try to return a value that could be nonzero only if the kernel
reported writing more bytes than we gave to it, hopefully a rare occurence.
Instead, assert that this doesn't happen.
Instead, return true if we got to the end of the iovec array. The caller
can use this information to know that the whole iovec array was written.
This allows one loop to be dropped in write_to_syslog().
Also drop _unlikely_: this function is called with very short arrays, and
it *is* likely that we trigger this condition. Let's just let the compiler
generate normal code without giving it a potentially false hint.
manager: emit a message when we fail to create manager because /run is not set up
$ SYSTEMD_LOG_LEVEL=debug build/systemd --test --user
...
Failed to lookup RuntimeDirectory path: No such device or address <---- this line is new
Failed to allocate manager object: No such device or address
We would fail and only say "Failed to allocate manager object: ENODEV" which is
not entirely self-explanatory. Let's add a better log message.
test: properly catch tests error with no /testok or empty /failed
When editing this function in 7bf20e48bd7d641a39a14a7feb749b7e8, I couldn't
decide whether to initialize ret at the top and only reset it on success, or
whether to assign a value in each branch. In the end I did neither ;( So if the
test finished without creating any of the result files, we would echo a
message, but return "success".
But there was bigger confusion with /failed: some tests create it empty, some
don't. I think we may want to do away pre-creation of /failed completely, and
assume the test failed unless /testok is found. But I'm leaving that for later
rework. For now let's just make sure we report return success only if /testok
or /skipped is found.

core: apply LogLevelMax to messages about units
This commit applies the filtering imposed by LogLevelMax on a unit's
processes to messages logged by PID1 about the unit as well.
The target use case for this feature is a service that runs on a timer
many times an hour, where the system administrator decides that writing
a generic success message to the journal every few minutes or seconds
adds no diagnostic value and isn't worth the clutter or disk I/O.
Debian has now been updated to patch the issue, so SemaphoreCI should
no longer fail. The fix has also been backported to the affected
stable branches.
Basically the same scenario as in a33e2692e162671f0d97856ad2f49a2620a1ec10, where `awk` exits as soon
as it finds a match, thus sending SIGPIPE to `ldd` if it's not fast
enough. That, in combination with `set -o pipefail` causes random &
unexpected fails, like:

Use BIOS characteristics to distinguish EC2 bare-metal from VMs
DMI vendor information fields do not provide enough information for us to
distinguish between Amazon EC2 virtual machines and bare-metal instances.
SMBIOS provides a BIOS Information
table (https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.4.0.pdf
Ch. 7) that provides a field to indicate that the current machine is a virtual
machine. On EC2 virtual machine instances, this field is set, while bare-metal
instances leave this unset, so we inspect the field via the kernel's
/sys/firemware/dmi/entries interface.

virt: detect Amazon EC2 Nitro instance
Amazon EC2 Nitro hypervisor is technically based on KVM[1], which
systemd-detect-virt identify propely from CPUID. However the lack of
CPUID on aarch64 (A1, T4 instance type) prevents a correct
identification, impacting hostnamectl and systemd-random-seed. Instead
it's possible to identify virtualization from DMI vendor ID.
