Hello Daniel, or anyone else affected,

Accepted systemd into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/237-3ubuntu10.45 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)

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

  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.
