+Subject: [PATCH] elf2efi: Fix header size calculation
+
+The PE header size calculation failed to take the PE magic and coff
+header size into account, which will lead to header truncation if we are
+writing only 5 sections.
+
+Upstream-Status: Backport [https://github.com/systemd/systemd/commit/ee91e06a5841c30bc7306260528ef407e0ebbab3]
