Title:
  text relocation of grep prevents its use under udevd

Status in grep package in Ubuntu:
  Invalid
Status in grep source package in Bionic:
  Fix Committed

Bug description:
  [Impact]
  grep can't be used under udev, preventing kdump-tools to be used after a memory hotplug.

  [Test case]
  Run grep with systemd-run -t --property MemoryDenyWriteExecute=yes /bin/grep crashkernel /proc/cmdline

  [Regression potential]
  The fix is a simple rebuild, so should have minimal potential for regression.

  
  -------------------------

  # systemd-run -t --property MemoryDenyWriteExecute=yes /bin/grep crashkernel /proc/cmdline
  Running as unit: run-u54.service
  Press ^] three times within 1s to disconnect TTY.
  /bin/grep: error while loading shared libraries: cannot restore segment prot after reloc: Operation not permitted
  #

  Under ppc64el, grep can't be used under udev, because it restricts
  mapping to be Write+Execute, with MemoryDenyWriteExecute=yes. A
  rebuild of grep under bionic fixes the issue.
