This update for systemd fixes the following issues: 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.
