Package: lshw Version: 02.18-0.1 Severity: normal Dear Maintainer,
lshw crashes with SEGV in privileged containers in Ubuntu, unless you disable the 'usb' test as follow : $ lshw -disable usb Note that the problem isn't reproducible in Debian because the container image doesn't contains the 2 files from where lshw try to get informations : /proc/bus/usb/devices /sys/kernel/debug/usb/devices thus stop at the following lshw verification : if (!exists(SYSKERNELDEBUGUSBDEVICES) && !exists(PROCBUSUSBDEVICES)) return false but in Ubuntu, lshw segfault in a privileged container because the actual lshw code only look if both doesn't exist or one of them is inaccessible (EACCESS).. then lshw segfault. For more informations about the Ubuntu bug : https://bugs.launchpad.net/bugs/1699161 Despite the fact that debian doesn't exhibit the situation, I think it would be great to consider this lshw PR since Ubuntu or other distributions relies on Debian for packages (merge, sync, ...) : https://ezix.org/src/pkg/lshw/pulls/9 The change is trivial, and only introduce a better mechanism to validate possible scenarios : if both files doesn't exist if 1/2 file exists if files can't be opene (EACCESS) ....
