+Subject: [PATCH] cryptsetup-generator: Don't mistake NULL input as OOM (#7688)
+
+Since systemd v236, several Arch users complained that
+systemd-cryptsetup-generator exits with an OOM error and that it
+prevents the boot from continuing.
+
+Investigating the diff of cryptsetup-generator between v235 and v236 I
+noticed that create_disk allowed for the `password` and `filtered`
+variables to be NULL (they're handled with `strempty()`) but not their
+`*_escaped` versions, and returned OOM errors in those cases.
+
+Fix this by checking that the input string is non-NULL before deciding
+that `specifier_escape` had an OOM error.
+
+I could not test this fix myself, but some users have reported success.
+
+Downstream bug: https://bugs.archlinux.org/task/56733
