loginctl ignoring user given sessions IDs at command-line

Ubuntu 16.10 seems unaffected.

 $ loginctl show-session 926 c2 927 | egrep Id=\|Leader
Id=926
Leader=24113
Id=c2
Leader=4175
Id=927
Leader=24212

 $ loginctl show-session c2 927 926 | egrep Id=\|Leader
Id=c2
Leader=4175
Id=927
Leader=24212
Id=926
Leader=24113

The patch has been accepted upstream:

https://github.com/systemd/systemd/commit/b0d08b056e73007695f2f001213da73d19802e23

This is not yet fixed in artful yet.

Just did a release to artful; I will do this one in the next update after this one.

This bug was fixed in the package systemd - 233-8ubuntu1

  Merge from experimental. Existing Ubuntu cherry-picks:
  * TEST-12: cherry-pick upstream fix for compat with new netcat-openbsd.
  * networkd: cherry-pick support for setting bridge port's priority.
    This is a useful feature/bugfix to improve feature parity of networkd with
    ifupdown. This matches netplan's expectations to be able to set bridge port's
    priorities via networked. This featue is to be used by netplan/MAAS/OpenStack.
  * Cherrypick upstream commit to enable system use kernel maximum limit for RLIMIT_NOFILE isntead of hard-coded (low) limit of 65536.
  * debian/tests/root-unittests: disable execute and seccomp tests on arm
    test-seccomp and test-execute fail on arm64 kernels. Marking both tests as
    expected failures. An upstream bug report is filed to resolve these.
  * Cherrypick upstream patch for vio predictable interface names.
  * Cherrypick upstream patch for platform predictable interface names.

  Ubuntu cherry-picks, now also applied in Debian:
  * resolved: fix null pointer dereference crash

  Remaining Ubuntu delta:
  * ubuntu: udev.postinst preserve virtio interfaces names on upgrades, on s390x.
    New udev generates stable interface names on s390x kvm instances, however, upon
    upgrades existing ethX names should be preserved to prevent breaking networking
    and software configurations.
    This patch only affects Ubuntu systems.
  * Skip starting systemd-remount-fs.service in containers
    even when /etc/fstab is present.
    This allows entering fully running state even when /etc/fstab
    lists / to be mounted from a device which is not present in the
    container.

  New Ubuntu cherry-picks:
  * loginctl: Chrerry-pick upstream fix to not ignore multiple session ids.
    (LP: #1682154)

This bug was fixed in the package systemd - 232-21ubuntu7

---------------
systemd (232-21ubuntu7) zesty; urgency=medium

  * networkd: accept `:' in ifnames in systemd/networkd. (LP: #1714933)
  * networkd: add support for ActiveSlave and PrimarySlave netdev options.
    (LP: #1709135)
  * Cherrypick upstream fix for a race between .mount and .automount units,
    which currently may result in automounts hanging. (LP: #1709649)
  * systemd.postinst: Fix-up version number check in the previous sru.
    The version check in the postinst was too tight, thus the SRU fix failed
    validation. (LP: #1710410)

systemd (232-21ubuntu6) zesty; urgency=medium

  * link: Fix offload features initialization.
    This fixes a regression introduced in v232 which caused TCP
    segmentation offloads being disabled by default, resulting in
    significant performance issues under certain conditions. (Closes: #864073)
    (LP: #1703393)
  * loginctl: Fix loginctl ignoring user given session IDs at command-line
    (LP: #1682154)
  * Disable fallback DNS servers.
    This causes resolved to call-home to google, attempt to access network when
    none is available, and spams logs. (LP: #1449001)
  * initramfs-tools: trigger udevadm add actions with subsystems first.
    This updates the initramfs-tools init-top udev script to trigger udevadm
    actions with type specified. This mimicks the
    systemd-udev-trigger.service. Without type specified only devices are
    triggered, but triggering subsystems may also be required and should happen
    before triggering the devices. This is the case for example on s390x with zdev
    generated udev rules. (LP: #1713536)
  * Enable systemd-resolved by default. (LP: #1710410)
  * core: fix systemd failing to serialize tasks correctly on daemon-reload.
    (LP: #1702823)
