  - CVE-2020-1712 (bsc#bsc#1162108) Fix a heap use-after-free vulnerability,
  when asynchronous Polkit queries were performed while handling Dbus
  messages. A local unprivileged attacker could have abused this flaw to
  crash systemd services or potentially execute code and elevate their
  privileges, by sending specially crafted Dbus messages.

  - Use suse.pool.ntp.org server pool on SLE distros (jsc#SLE-7683)

  - libblkid: open device in nonblock mode. (bsc#1084671)

  - udev/cdrom_id: Do not open CD-rom in exclusive mode. (bsc#1154256)

  - bus_open leak sd_event_source when udevadm trigger (bsc#1161436
  CVE-2019-20386)

  - fileio: introduce read_full_virtual_file() for reading virtual files in
  sysfs, procfs (bsc#1133495 bsc#1159814)

  - fileio: initialize errno to zero before we do fread()

  - fileio: try to read one byte too much in read_full_stream()

  - logind: consider 'greeter' sessions suitable as 'display' sessions of a
  user (bsc#1158485)

  - logind: never elect a session that is stopping as display

  - journal: include kmsg lines from the systemd process which exec()d us
  (#8078)

  - udevd: don't use monitor after manager_exit()

  - udevd: capitalize log messages in on_sigchld()

  - udevd: merge conditions to decrease indentation

  - Revert 'udevd: fix crash when workers time out after exit is signal
  caught'

  - core: fragments of masked units ought not be considered for
  NeedDaemonReload (#7060) (bsc#1156482)

  - udevd: fix crash when workers time out after exit is signal caught

  - udevd: wait for workers to finish when exiting (bsc#1106383)

  - Improve bash completion support (bsc#1155207)

  * shell-completion: systemctl: do not list template units in {re, }start

  * shell-completion: systemctl: pass current word to all list_unit*

  * bash-completion: systemctl: pass current partial unit to list-unit*
  (bsc#1155207)

  * bash-completion: systemctl: use systemctl --no-pager

  * bash-completion: also suggest template unit files

  * bash-completion: systemctl: add missing options and verbs

  * bash-completion: use the first argument instead of the global variable
  (#6457)

  - networkd: VXLan Make group and remote variable separate (bsc#1156213)

  - networkd: vxlan require Remote= to be a non multicast address (#8117)
  (bsc#1156213)

  - fs-util: let's avoid unnecessary strerror()

  - fs-util: introduce inotify_add_watch_and_warn() helper

  - ask-password: improve log message when inotify limit is reached
  (bsc#1155574)

  - shared/install: failing with -ELOOP can be due to the use of an alias in
