Title:
  getgrouplist is not thread safe with libnss_systemd

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Bionic:
  Fix Committed
Status in systemd source package in Focal:
  Fix Committed

Bug description:
  [impact]

  programs calling getgrouplist() may crash as it is not thread-safe

  [test case]

  see upstream bug description for sample c program to reproduce:
  https://github.com/systemd/systemd/issues/17007#issue-698123284

  [regression potential]

  any regression would likely occur when creating a hashmap in systemd,
  or when any multi-threaded programs concurrently create (and use) the
  hashmap

  [scope]

  this is needed for f and b

  this is fixed upstream by commit
  ae0b700a856c0ae460d271bb50dccfaae84dbcab, already included in g/h (per
  comment 1).

  [original description]

  This upstream issue (https://github.com/systemd/systemd/issues/17007)
  is affecting the latest version of systemd in Ubuntu Focal. It has
  been fixed upstream with
  https://github.com/systemd/systemd/pull/17033. Can we have this
  patched for Focal please as it causes Mesos to randomly segfault on
  start.
