Description Adam Williamson 2024-12-05 00:54:25 UTC
Description of problem:
Seen on boot after a Rawhide system update. The update did not include iio-sensor-proxy, but did include a libselinux update from 3.7-6 to 3.7-7.
SELinux is preventing iio-sensor-prox from 'write' accesses on the file current_trigger.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that iio-sensor-prox should be allowed write access on the current_trigger file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'iio-sensor-prox' --raw | audit2allow -M my-iiosensorprox
# semodule -X 300 -i my-iiosensorprox.pp
