-Subject: [PATCH] sd-event: change ordering of pending/ratelimited events
-
-Instead of ordering non-pending before pending we should order
-"non-pending OR ratelimited" before "pending AND not-ratelimited".
-This fixes a bug where ratelimited events were ordered at the end of the
-priority queue and could be stuck there for an indeterminate amount of
-time.

-Subject: [PATCH] basic/unit-name: do not use strdupa() on a path
-
-The path may have unbounded length, for example through a fuse mount.
-
-CVE-2021-33910: attacked controlled alloca() leads to crash in systemd and
-ultimately a kernel panic. Systemd parses the content of /proc/self/mountinfo
-and each mountpoint is passed to mount_setup_unit(), which calls
-unit_name_path_escape() underneath. A local attacker who is able to mount a
-filesystem with a very long path can crash systemd and the whole system.
-
-https://bugzilla.redhat.com/show_bug.cgi?id=1970887
-
-The resulting string length is bounded by UNIT_NAME_MAX, which is 256. But we
-can't easily check the length after simplification before doing the
-simplification, which in turns uses a copy of the string we can write to.
-So we can't reject paths that are too long before doing the duplication.
-Hence the most obvious solution is to switch back to strdup(), as before
