Title:
  [Ubuntu] lsqeth core dumps when called from sosreport

Status in Ubuntu on IBM z Systems:
  Incomplete
Status in s390-tools package in Ubuntu:
  Incomplete

Bug description:
  ---Problem Description---
  In the zCX (Open Containers for z/OS), we run in an environment where we have no eth devices defined and therefore no /sys/bus/ccwgroup exists.  We are experiencing intermittent problems with a segmentation fault in the lsqeth program.

  In particular when called from sosreport it consistently fails  but if
  invoking directly from the command line, it most likely does not cause
  an error.

  We found out that the logic of lsqeth from s390-tools always expect
  the directory '/sys/bus/ccwgroup/drivers/qeth/'  to be existed.  And
  it doesn't handle the scenario if the directory doesn't exist and
  causes the core dump in our case.

  IBM willl provide an upstream patch for s390tools once available.

  This package upgrade need to released by Bionic as soon as possible.

  ---uname output---
  4.15.0-42-generic
   
  Machine Type = system Z 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
   1. run in an environment with no eth devices defined and therefore no /sys/bus/ccwgroup exists. 
  2. timeout 10 lsqeth
