Three defects that were latent until GCC 14+ made implicit declarations
and pointer-type mismatches errors. None was a missing implementation --
in every case the code existed and only the declaration was wrong.
libinput
Carried its own bundled libudev.h that shadowed the real one from the
libudev recipe, which it already declares as a dependency. The bundled
copy lacked udev_device_get_sysattr_value(), so udev/libinput-device-
group.c got an implicit declaration and then an int-to-pointer
assignment. The real header is a strict superset -- nothing is declared
in the bundled copy that the real one lacks -- so the bundled file is
dead code that shadows a real implementation, which
LOCAL-FORK-SUPREMACY-POLICY.md Rule 4 requires removing.
linux-kpi
ieee80211_register_rx_handler() is fully implemented in
src/rust_impl/mac80211.rs as #[no_mangle] extern "C", and
ieee80211_rx_drain()'s own doc comment refers to it, but it was never
declared in c_headers/net/mac80211.h. Declared it.
redbear-iwlwifi
- rb_iwlwifi_bridge_register_rx() is used ~1800 lines before its
definition with no forward declaration. Added one at file scope.
- bridge_rx_callback was declared here as taking void *hw, while its
Rust definition in src/bridge/callback.rs takes *mut Ieee80211Hw and
linux-kpi's RxCallback type expects struct ieee80211_hw *. The C
declaration was simply wrong; corrected to match the implementation.
All three cook clean.
libinput
libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.
libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.
User documentation
Documentation explaining features available in libinput is available here.
This includes the FAQ and the instructions on reporting bugs.
