hwdb: add database entries for Yamaha mLAN 3rd generation
TC Applied Technologies designed DiceII ASIC to adapt to two protocols.
One of the protocol is mLAN defined by Yamaha Corporation, and another
is own protocol. The DiceII ASIC adapted to mLAN protocol was used some
products by Yamaha and its child company, Steinberg.
The content of configuration ROM for the models has completely different
layout from the one defined by 1394 Trading Association.
This commit adds an udev rule for the models. At present, no driver is
developed, thus this is just for convenience to developers.
hwdb: add database entries for Yamaha mLAN 2nd generation
Yamaha Corporation designed mLAN protocol based on IEEE 1394

hwdb: add database entries for models based on DICE ASICs with TCAT specification
TC Applied Technologies designed the series of ASIC for audio and music
data transmission in several types of communication bus. It's named as
Digital Interface Communication Engine (DICE). Four ASICs are known in
the series for IEEE 1394 bus; Dice II, TCD2210 (Dice Jr.), TCD2220 (Dice
Mini), and TCD3070 (DiceIII).

This commit adds database entries for models without any customization by

number in the order. In the specification, the value of category field is
fixed to 0x04. The root directory includes leaf entries for vendor and

hwdb: allow parser to expect usage of slash sign in value of property
Although in IEEE 1394 unit function list I have a plan to use slash sign

When parsing current entries in database excluded from parser testing, we
can find usage of slash sign in name of property.
This commit adds slash sign in allow list of the parser for my
convenience.
hwdb: add parser grammar for IEEE 1394 unit function list
In added IEEE 1394 unit function list, I use custom key to detect unit
entries in node context. Although the list is not widely used in the most
of systemd users, I would like to add parser grammar for testing, by
borrowing a bit time in builders.
Current udev rules configures group owner of firewire character device
to video group, corresponding to nodes in IEEE 1394 in below cases:
1.the node with any unit for any minor version of IIDC version 1
specification defined by 1394 Trading Association
2.the node with any unit for specification defined by Point Grey Research
3.the node with any unit for AV/C device v1.0 defined by 1394 Trading
Association
4.the node with any unit for vendor-unique protocol defined by 1394
Trading Association
Nevertheless, case 3 and 4 can cover the node with any unit for audio
function as well. In the cases, it's convenient to assign audio group.
Additionally, some nodes are known to have layout different from
the specification defined by 1394 Trading Association. In the case,
it's required to add rules specific to them.
Furthermore, some nodes have no fields for vendor name and model name in
configuration ROM. In the case, it's required to add entries to hardware
database for users convenience.
For the above reasons, this commit adds rules to use information in
hardware database for known units in IEEE 1394. One database entry
corresponds to one unit. Two types of key are used to match the unit;
customized key from node context, kernel modalias of unit context.
The entry has the type of function, at least. Supplementally, it has
vendor and model names.
For your information, below statements with Python pyparsing module are
expected to parse all of the custom key and module alias in the list:
The s390 PCI driver assigns the hotplug slot name from the
function_id attribute of the PCI device using a 8 char hexadecimal
format to match the underlying firmware/hypervisor notation.
Further, there's always a one-to-one mapping between a PCI
function and a hotplug slot, as individual functions can
hot plugged even for multi-function devices.
As the generic matching code will always try to parse the slot
name in /sys/bus/pci/slots as a positive decimal number, either
a wrong value might be produced for ID_NET_NAME_SLOT if
the slot name consists of decimal numbers only, or none at all
if a character in the range from 'a' to 'f' is encountered.
Additionally, the generic code assumes that two interfaces
share a hotplug slot, if they differ only in the function part
of the PCI address. E.g., for an interface with the PCI address
dddd:bb:aa.f, it will match the device to the first slot with
an address dddd:bb:aa. As more than one slot may have this address
for the s390 PCI driver, the wrong slot may be selected.
To resolve this we're adding a new naming schema version with the
flag NAMING_SLOT_FUNCTION_ID, which enables the correct matching
of hotplug slots if the device has an attribute named function_id.
The ID_NET_NAME_SLOT property will only be produced if there's
a file /sys/bus/pci/slots/<slotname> where <slotname> matches
the value of /sys/bus/pci/devices/.../function_id in 8 char
hex notation.

dissect-image: filter out enumerated or triggered devices without "partition" sysattr
This also adds more filters for device enumerator and monitor.

the xattrs instead of assuming it will be NONE.

We would pass an initialized value to a helper function. We would only *use*

UB, so let's not do that. This silences a gcc warning.

The old code was just fine, but gcc doesn't understand that max_brightness is

get_max_brightness() just retrieves and parses the attribute, and the main
function decides what to do with it.

It actually doesn't, but the compiler has a point here: the code is specified
in sd_bus_error_map[], and it has no way of knowning that we want it to be a
positive value.
I think this should be an assert, because if this assumption fails, a

nss-resolve: fix parsing of io.systemd.Resolve.ResolveAddress reply
Since the switch to varlink in 0c73f4f075a2d23f7cabe708b589f19f4bbbec37, the

meant that we'd reject any reply. Once past that, the code would use
unitialized 'c' and 'n' variables, so it's lucky we never got that far ;)
With -Wmaybe-unitialized, gcc would warn.
I think that declaring the huge list of local variables with very short names
at the top of the function was making it harder to understand what is going on
in the function. So let's rename the variables a bit, and initialize them upon
declaration if possible.

accepting 'disable --now' but not 'enable --now' seems overly complex. So I

shared: add new IMAGE_VERSION=/IMAGE_ID= field to /etc/os-release
This specifes two new optional fields for /etc/os-release:
IMAGE_VERSION= and IMAGE_ID= that are supposed to identify the image of
the current booted system by name and version.
This is inspired by the versioning stuff in
https://github.com/systemd/mkosi/pull/683.
In environments where pre-built images are installed and updated as a
whole the existing os-release version/distro identifier are not
sufficient to describe the system's version, as they describe only the
distro an image is built from, but not the image itself, even if that
image is deployed many times on many systems, and even if that image
contains more resources than just the RPMs/DEBs.
In particular, "mkosi" is a tool for building disk images based on
distro RPMs with additional resources dropped in. The combination of all
of these together with their versions should also carry an identifier
and version, and that's what IMAGE_VERSION= and IMAGE_ID= is supposed to
be.
basic/fileio: fix reading of not-too-small virtual files
This code is trying to do two things: when reading a file with working
st.st_size, detect when the file size changes between the fstat() and our
allocation of the buffer based on the returned size, and the subsequent read().
When reading a file without st.st_size, read up to READ_FULL_BYTES_MAX.
But this second scenario was partially broken: we'd start with size = 4095, and
double the size up to three times, i.e. up to 32767. But we want to read up to
READ_FULL_BYTES_MAX.
So let's listentangle the two cases a bit: if a file returns non-zero st._size,
proceed as before. But if we don't know the size, let's immediately allocate
the buffer of maximum size of READ_FULL_BYTES_MAX. I think that allocating 4MB
and 1MB is going to take pretty much the same time as long as the memory is not
written to, so by allocating 1MB, 2MB, and 4MB, we wouldn't really be saving
anything internally, but wasting time on repeated reads, if the file is long
enough.
Also, don't do the seek if we know we're going to return an error immediately
after.
This should fix reading of any files in /proc, which all have size == 0. In
particular, various files read by coredump might be larger than 32767.
What about /sys? The file there return a fake value, usually 4096. So we'll
allocate a small buffer and read that.
