Strace when trying to load the driver

When trying to use upsdrv with an Eaton UPS connected via USB using the usbhid-ups driver on a kernel using GRKERNSEC_SYSFS_RESTRICT the driver can't find the device.

strace shows that the system tries to access /sys/bus/usb/devices to find the devices but is not allowed.

A solution to this would be getting a whitelisted group which is allowed access to the sysfs filesystem or more finegrained controls.

I think I never had the chance to tell spender about this, sorry. I'm CCing he now.

ping @upstream.  Anything to do here?
Comment 3 Francisco Blas Izquierdo Riera (RETIRED) gentoo-dev 2018-07-08 14:28:55 UTC 
I'm closing as the system no longer uses hardened sources so testing will be impossible.
