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.

sd-bus: Deal with cookie overruns. (bsc#1150595)

rules: Add by-id symlinks for persistent memory. (bsc#1140631)

Drop the old fds used for logging and reopen them in the sub process
 before doing any new logging. (bsc#1154948)

Fix warnings thrown during package installation (bsc#1154043)

Fix for systemctl hanging by restart. (bsc#1139459)

man: mention that alias names are only effective after 'systemctl
 enable'. (bsc#1151377)

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

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

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

udev: fix 'NULL' deref when executing rules. (bsc#1151506)

Introduce function for reading virtual files in 'sysfs' and 'procfs'.
 (bsc#1133495, bsc#1159814)");
