Chris Lindee [Mon, 16 Feb 2026 06:47:15 +0000 (00:47 -0600)] 
profile/systemd-osc-context: Acknowledge uncertainty

Bash does not provide an easy way to discern if an exit status came from
a signal, or was a legitimate non-zero exit (i.e. a failure).  It can be
done, by using job control or by invoking another program; however, such
approaches require modifying the command entered by a user and are, thus,
invasive and risky.

Since an exit status of 129 on a command could either indicate it exited
cleanly with `exit(129)` or was interrupted by `SIGHUP`, the osc context
should report both possibilities, to acknowledge our uncertainty.  Given
we have no idea what happened, besides an unsuccessful exit, the exit is
described as `exit=failure`.

Moreover, discerning between an `interrupt` and a `crash` with a command
likely involves categorizing every signal.  It is fairly obvious `SIGINT`
is an interrupt and also obvious, IMO, that `SIGSEGV` is a crash.  Avoid
the complication (and potential disagreements) by using the encompassing,
generic value — one that remains true if no signal occurred.

Chris Lindee [Mon, 16 Feb 2026 06:08:31 +0000 (00:08 -0600)] 
profile/systemd-osc-context: Bring exit up to spec

The exit status should be compared against 128 — not 127 — as the Bash
manual, under the EXIT STATUS section, states [0]:

    When a command terminates on a fatal signal N, bash uses the value
    of 128+N as the exit status.

    If a command is not found, the child process created to execute it
    returns a status of 127.  If a command is found but is not
    executable, the return status is 126.

Furthermore, UAPI.15 specifies the `signal` value must be the symbolic
signal name, not a numerical value [1].  Luckily, POSIX.1-2008 ensures
the shell must supply `kill -l`, which must be able to convert `$?` to
the signal that could cause such an exit in that shell [2].  It should
be noted that only a select handful of signals have a standard numeric
value; all others are implementation-defined [3].  This is why UAPI.15
requires the symbolic name, as the value may differ across systems.

Notably, not every value above 128 needs to correspond to a signal; on
my Linux system, only exit codes 129–192 indicate a signal.  Again, we
can use `kill -l`, which will exit non-zero when an exit code does not
come from a signal (plus 128) [4].

Signal 0 (which would correspond to exit code 128) is reserved for the
null signal, per POSIX.1-2008 [5], and therefore will never be an exit
signal.

This change brings the implementation into compliance.

is being done at all right now). Moreover, currently the event
priority is hardcoded, while event loop and associated priority
assignment ought to be subject to each daemon.

While fixing the mentioned issues I took the chance to restructure

for the metrics server is still missing - it will be tackled

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.

backlight: reduce clamp to 1%

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

oomd: Return tristate status from oomd_cgroup_kill_mark()

is thus unreachable.

Changing it to `r >= 0` would also be wrong, because then we would log

So let's fix this by making the return value express what actually

oomd: Fix bug where we drop queued kill state on duplicate cgroup

oomd_cgroup_kill_mark() allocates a temporary OomdKillState and inserts
it into kill_states via set_ensure_put(). This is keyed by cgroup path.
When the same cgroup is already queued, set_ensure_put() dutifully
returns 0.

The function then returns with
_cleanup_(oomd_kill_state_removep) still armed, which eventually calls
oomd_kill_state_free().

oomd_kill_state_free() removes from kill_states by cgroup-path key, so
because this path already exists, it will remove the existing queued
kill state instead of just dropping the temporary object.

This is wrong and results in mistakenly drops the queued kill state on
duplicates.

This can happen when a cgroup is marked multiple times before the first
queued kill state is consumed. The result is lost kill-state tracking
and incorrect prekill/kill sequencing.

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.
