If a device exposes more than 16 mouse buttons, we run into the BTN_JOYSTICK
range, also labelling it as joystick. And since 774ff9b this results in only
ID_INPUT_JOYSTICK but no ID_INPUT_MOUSE.
Fixes#8460
This is similar to TAKE_PTR() but operates on file descriptors, and thus
assigns -1 to the fd parameter after returning it.
Removes 60 lines from our codebase. Pretty good too I think.
This macro will read a pointer of any type, return it, and set the
pointer to NULL. This is useful as an explicit concept of passing
ownership of a memory area between pointers.
This takes inspiration from Rust:
https://doc.rust-lang.org/std/option/enum.Option.html#method.take
and was suggested by Alan Jenkins (@sourcejedi).
It drops ~160 lines of code from our codebase, which makes me like it.
Also, I think it clarifies passing of ownership, and thus helps
readability a bit (at least for the initiated who know the new macro)
safe_atou16_full() is like safe_atou16() but also takes a base
parameter. safe_atou16() is then implemented as inline function on top
of it, passing 0 as base. Similar safe_atoux16() is reworked as inline
function too, with 16 as base.
If we can't send a message this is no reason to completely abort the
event handler.

The type is "ssize_t", not "int", let's be accurate about that, as these
types are different on some archs.
Given that we don't actually care about the return value reall, drop
the whole assignment, just check if negative.
Let's use first_word() instead of startswith(), it's more explanatory
and a bit more correct. Also, let's use the return value instead of
adding +9 when looking for the second part of the directive.
.include lines are already deprecated somewhat, and for example
explicitly not mentioned in the documentation for this reason. Let's get
one step further and generatea warning when we encounter them (but still
process them).
Why are they deprecated? Because they are semantically awful — they
complicate stat() based mtime checks for configuration files and they
allow arbitrary loops we currently have zero protection against and
really shouldn't have to have.
Let's make sure we always initialize the return value if we return
non-negative.
Just a matter of coding style: we should always initialize our return
values when we return >= 0, and leave them unclobbered if we return < 0.
The warning is not emitted for absolute paths like /dev/sda or /home, which are
converted to .device and .mount unit names without any fuss.
Most of the time it's unlikely that users use invalid unit names on purpose,
so let's warn them. Warnings are silenced when --quiet is used.
$ build/systemctl show -p Id hello@foo-bar/baz
Invalid unit name "hello@foo-bar/baz" was escaped as "hello@foo-bar-baz" (maybe you should use systemd-escape?)
Id=hello@foo-bar-baz.service
$ build/systemd-run --user --slice foo-bar/baz --unit foo-bar/foo true
Invalid unit name "foo-bar/foo" was escaped as "foo-bar-foo" (maybe you should use systemd-escape?)
Invalid unit name "foo-bar/baz" was escaped as "foo-bar-baz" (maybe you should use systemd-escape?)
Running as unit: foo-bar-foo.service
Fixes#8302.
Let's better check this inside of the call than before it, so that we
never issue this while reloading, even should these calls be called due
to other reasons than just the unit notify.
This makes sure the reload state is unset a bit earlier in
manager_reload() so that we can safely call this function from there and
they do the right thing.
Follow-up for e63ebf71ed.
Since 2016, Hyperv devices moved to using standard way to expose UUID to sysfs. Fix the parsing function to work with the newer format.
Change log:
v2: changed code to work with both old and new path format
v3: changed guid_str_len type to size_t, fixed length in char guid[] in handle_scsi_hyperv()
