Security issues fixed:

CVE-2021-33910: Fixed a denial of service (stack exhaustion) in systemd
 (PID 1) (bsc#1188063)

Other fixes:

mount-util: shorten the loop a bit (#7545)

mount-util: do not use the official MAX_HANDLE_SZ (#7523)

mount-util: tape over name_to_handle_at() flakiness (#7517) (bsc#1184761)

mount-util: fix bad indenting

mount-util: EOVERFLOW might have other causes than buffer size issues

mount-util: fix error propagation in fd_fdinfo_mnt_id()

mount-util: drop exponential buffer growing in name_to_handle_at_loop()

udev: port udev_has_devtmpfs() to use path_get_mnt_id()

mount-util: add new path_get_mnt_id() call that queries the mnt ID of a
 path

mount-util: add name_to_handle_at_loop() wrapper around
 name_to_handle_at()

mount-util: accept that name_to_handle_at() might fail with EPERM (#5499)

basic: fallback to the fstat if we don't have access to the
 /proc/self/fdinfo

sysusers: use the usual comment style

test/TEST-21-SYSUSERS: add tests for new functionality

sysusers: allow admin/runtime overrides to command-line config

basic/strv: add function to insert items at position

sysusers: allow the shell to be specified

sysusers: move various user credential validity checks to src/basic/

man: reformat table in sysusers.d(5)

sysusers: take configuration as positional arguments

sysusers: emit a bit more info at debug level when locking fails

sysusers: allow force reusing existing user/group IDs (#8037)

sysusers: ensure GID in uid:gid syntax exists

sysusers: make ADD_GROUP always create a group

test: add TEST-21-SYSUSERS test

sysuser: use OrderedHashmap

sysusers: allow uid:gid in sysusers.conf files

sysusers: fix memleak (#4430)

These commits implement the option '--replace' for systemd-sysusers so
 %sysusers_create_package can be introduced in SLE and packages can rely
 on this rpm macro without wondering whether the macro is available on
 the different target the package is submitted to.

Expect 644 permissions for /usr/lib/udev/compat-symlink-generation
 (bsc#1185807)

systemctl: add --value option

execute: make sure to call into PAM after initializing resource limits
 (bsc#1184967)

rlimit-util: introduce setrlimit_closest_all()

system-conf: drop reference to ShutdownWatchdogUsec=

core: rename ShutdownWatchdogSec to RebootWatchdogSec (bsc#1185331)

Return -EAGAIN instead of -EALREADY from unit_reload (bsc#1185046)

rules: don't ignore Xen virtual interfaces anymore (bsc#1178561)

write_net_rules: set execute bits (bsc#1178561)

udev: rework network device renaming

Revert 'Revert 'udev: network device renaming - immediately give up if
 the target name isn't available''");
