[Bug 1845337] Re: Disco autopkgtest @ armhf fails root-unittests -> test-execute -> exec-dynamicuser-statedir.service

[Launchpad Bug Tracker]

This bug was fixed in the package systemd - 242-7ubuntu1

---------------
systemd (242-7ubuntu1) eoan; urgency=medium

  * Merge from unstable
  * UBUNTU: drop setting fs.protected_regular and fs.protected_fifos from
    sysctl defaults shipped by systemd (LP: #1845637)
    File: debian/patches/debian/UBUNTU-drop-kernel.-settings-from-sysctl-defaults-shipped.patch
    https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/systemd/commit/?id=6e583847b04c3f83a50f3bd6947dcae6a73d8388
  * test-execute: Filter /dev/.lxc in exec-dynamicuser-statedir.service.
    It appears in nested LXC containers and broke the armhf autopkgtest.

systemd (242-7) unstable; urgency=medium

  * sleep: properly pass verb to sleep script
  * core: factor root_directory application out of apply_working_directory.
    Fixes RootDirectory not working when used in combination with User.
    (Closes: #939408)
  * shared/bus-util: drop trusted annotation from
    bus_open_system_watch_bind_with_description().
    This ensures that access controls on systemd-resolved's D-Bus interface
    are enforced properly.
    (CVE-2019-15718, Closes: #939353)

Bug description:
  Since the recent few weeks systemd autopkgtest @ armhf @ disco fail
  [1].

  The log is very (very) long and partially interwoven due to concurrent execution.
  Somewhere in between we see this subcase is the one failing: root-unittests
  Of this test (which again has many subtests) it is: test-execute
  And of this again it is (always):

  I'll attach bad and good case full and stripped logs.

  
  The diff of those comes down to just:
  1. execute a find in a shell
  2. shell exits
  3. exec-dynamicuser-statedir.service: Main process exited, code=exited, status=0/SUCCESS
  vs
  3. exec-dynamicuser-statedir.service: Main process exited, code=exited, status=1/FAILURE
  4. in the bad case that triggers an assertion
  The find that fails is:

  find / -path /var/tmp -o -path /tmp -o -path /proc -o -path
  /dev/mqueue -o -path /dev/shm -o -path /sys/fs/bpf

  Good and bad case are the same most recent version
  systemd/240-6ubuntu5.7.

  Maybe something is bad in the containers we have for armhf in regard to these paths?
  Was there any change we'd know of?

  If there is nothing known, could we force-badtest it to get it out of
  the way of ongoing migrations?
