Title:
  ltp-syscalls: sgid inheritance for non-directories behavior changed

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Cosmic:
  Invalid

Bug description:
  ltp syscalls open10 and and creat08 try to create an sgid executable
  file inside a sgid directory owned by a group whose members do not
  include the process user.

  That used to work up to commit
  0fa3ecd87848c9c93c2c828ef4c3a8ca36ce46c7 ("Fix up non-directory
  creation in SGID directories").

  This was backported to 4.17.9 and so affects the current kernel in
  cosmic proposed, and breaks such ltp tests.
