Comment 7 for bug 1699161

Update:

I've been asked to look at this problem

It does segfault on Xenial, but it is also reproducible using Zesty privileged container.

In fact, it is a behavior not yet reported nor fix upstream. I can confirm it by having tested the reproducer against the latest and greatest compiled by hand lshw binary using Xenial privileged container.

It tries to open '/sys/kernel/debug/usb/devices' that exist but doesn't have permission to be fopen and then try '/proc/bus/usb/devices' which doesn't exist. I agree with Rafael that there must be a better mechanism to be protected against this situation.

--
root@priv:/tmp/lshw# ls -altr /proc/bus/usb/devices
ls: cannot access '/proc/bus/usb/devices': No such file or directory

root@priv:/tmp/lshw# ls -altr /sys/kernel/debug/usb/devices
-r--r--r-- 1 root root 0 Oct 11 11:19 /sys/kernel/debug/usb/devices

root@priv:/tmp/lshw# cat /sys/kernel/debug/usb/devices
cat: /sys/kernel/debug/usb/devices: Permission denied
---

So this look like it'll need to be fix upstream first.
I'll start to look at it.

I tried to create a new ticket with ezIX without success, their tracker is giving me errors.
I have emailed Lyonel Vincent, so he can hopefully file the bug on our behalf.
