The new varlink methods are basically equivalent to 'ip link set INTERFACE up/down',
but they support polkit authentication. Also, on LinkDown, it gracefully
stops dynamic engines like DHCP client/server before the interface is
bring down. Hence, e.g. an empty RA on stop should be sent.

Actually we are defining databases to determine when a usb device is
inherent part of the system or if it's a external device.
Let's use the removable attribute of the port where it is connected to
say that. That gives us the ability to not rely on a particular vendor
only does external devices or to not having the need to be quirking
input subsystem for that purpose that will become unreliable as more and
more internal devices are connected over usb instead over ps2 or i2c
buses. Eg.
https://gitlab.freedesktop.org/libinput/libinput/-/commit/02b495e79022e64514015e1a3dea32997035dd4f?merge_request_iid=1389
Actually this has been seen as reliable in a small set of device from
normal laptops, to detachable ones. The need to check maxchild is 0 is
for detachable devices, pogo pin usbs are fixed, while we attach the
keyboard|touchpad dock the input devices tend to be directly connected
to that port and if the dock has more usbs tend to be a hub that then
exposes removable as unknow. If we don't set maxchild 0 we will not only
guess that the keyboard and touchpad are internal but also incorrectly
other input devices like mice connected to the dock's usb ports.
I have use a very generic name like INTEGRATION because is not actually
used for any other thing and is used to determine not only over usb bus
but for acpi, pci, platform actually.
Also a remap to actual libinput variables is done for compatibility
purposes. if it's possible to have only the INTEGRATION variable instead
multiple ones will be done in the future but is actually unclear.
This can also be used for example to achieve an actual feature that we
lack in linux, when a device with accelerometers and cameras is rotated
the video output is not, this tag the own device cameras as internal
while external ones as external to be able to only do that for the
internal ones.
Note that this has nothing to do with the removable attribute found in
usb storage devices where it's values can be 0 or 1. There is no
conflict at all because the removable attribute we check is specifically
the one found in usb port ones.
Actually GNOME sets a clamp of 1% and divides in 20 steps the brightness
control. Using 5% clamp makes things like in a device with max value 640
to always be in the first brightness step in GNOME and we can't leave in
the minimum.
GNOME set steps of 640/20 = 32 with the zero step 640 * 1% = 6. When we
restart the device with the lowest bright systemd sees 6 but sets
640 * 5% = 32, so we get the brightness in the first step.
Tests in IPS and OLED panels have been done and 1% still seems a
comprensive minimun usable value so use that to allow all environments
to be able to set lower brightness values that won't be raised by
systemd at boot.
If your user enviroment allow to set excesive lower unusable values you
should blame it or yourself if you directle changes it through sysfs but
not systemd.
UEFI Block I/O Protocol has `Media->IoAlign` field dictating the minimum
alignment for I/O buffer. It's quite surprising this has been lingering
here unnoticed for years, seems like most UEFI implementations have
small or no alignment requirements. U-Boot is not the case here, and
requires at least 512 byte alignment, hence attempt to read GPT
partition table fail and in effect systemd-boot can not find XBOOTLDR
partition.
These patches allow to boot from XBOOTLDR partition on U-Boot - tested
with latest systemd revision and U-Boot master
(`8de6e8f8a076d2c9b6d38d8563db135c167077ec`) on x64 and ARM32, of which
both are failing without the patch.
Also fixes Bitlocker probing logic, which is the only other place where
raw block I/O is used, however this is untested.
While looking at oomd behaviour in production I noticed that I always
get garbage cgroup paths for the Killed event. Looking more closely, I
noticed that while the signature is (string cgroup, string reason), we
currently erroneously pass the `OomdCGroupContext*` pointer itself as
the first argument to sd_bus_emit_signal(), rather than the ctx->path
string it contains.
The in-memory layout on affected machines in my case is:
struct OomdCGroupContext {
unsigned n_ref;
/* padding */
char *path;
/* ... */
}
...which explains the control characters, since they're garbage from
parsing n_ref, the path pointer, and later fields. At runtime, sd-bus
treats ctx as `const char *` and reads struct bytes as string data,
resulting in garbage being sent.
Pass ctx->path correctly so listeners receive the valid cgroup path.
string_has_ansi_sequence() currently does this to look for ESC input:
t = memchr(s, 0x1B, ...)
So each iteration re-searches from the original start pointer. But if we
find an ESC byte that does *not* start a valid ANSI sequence (like "\x1B
", or an ESC at the end of the string), then ansi_sequence_length()
returns 0, and if that ESC is still in the search window, we will just
spin consuming 100% CPU forever.
Fix this by always advancing past rejected ESC bytes.
Using --first-parent --no-merges seems to exclude not just the merge
commits but all the commits from the merge as well. Let's use only
--no-merges to get just the commits without merges.
Building these over and over again is extremely wasteful. Let's just
build them once and not touch them again unless -ff is specified or
their cache is out-of-date, which is exactly what Incremental=relaxed
does.
This means mkosi.extra/ and such changes won't be picked up for these
anymore unless -ff is used, but that slight annoyance is totally
outweighed by the time saved building the images.
A more straightforward way to extend the default initrd rather than
using a subimage. This mainly allows us to take advantage of mkosi
automatically figuring out whether the initrd needs to be built or not,
speeding up builds when building directory images as the initrd can be
skipped in that case.

TEST-02-UNITTESTS.sh[4382]: [ 707.393188] test-cgroup-util[426]: Failed to open pidfd for pid 414: Invalid argument
TEST-02-UNITTESTS.sh[4382]: [ 707.393193] test-cgroup-util[426]: src/test/test-cgroup-util.c:249: Assertion failed: Expected "r = proc_dir_read_pidref(d, &pid)" to succeed, but got error: -22/EINVAL
```
The kernel can return EINVAL on pidfd_open() when the selected PID is
not a thread group leader. Don't fail the test, as we are iterating on
everything, so this can seldomly happen.
For some reason the VS Code parser thinks sd_json_variant is still 48 bytes,
so skip the assert when running in that parser too
Follow-up for 337712e777
The assert at the bottom was updated when the size changed, but
the comment wasn't:
assert_cc(sizeof(sd_json_variant) == 40U);
Follow-up for 337712e777
When sd_varlink_connect_url() gets an unknown URL we now
check if there is a `$LIBEXECDIR/varlink-bridges/$scheme`
binary and execute it (with the url as the first arguments).
This makes varlink more flexible as it provides a way to
dynamically add "bridges" in LIBEXECDIR/varlink-bridges/. This is
conceptually similar to the libvarlink `varlink --bridge` command
and allows to e.g. call varlink over http{,s} via e.g. the new
varlink-http-bridge.
With a running varlink-http-bridge [0] one can do:
```console
$ varlinkctl call http://localhost:8080/ws/sockets/io.systemd.Hostname \
io.systemd.Hostname.Describe {}
{
"Hostname" : "top",
...
```
