Historically grub2 built image paths using two File Path nodes - one for directory and one for file name relative to directory. These nodes had path names that were not NULL terminated. Recently we had bug report that secure boot using grub2 failed. It was tracked down to exactly the fact that paths were not NULL terminated. See http://git.savannah.gnu.org/cgit/grub.git/commit/?id=ce95549cc54b5d6f494608a7c390dba3aab4fba7 Unfortunately this caused another regression which looks like firmware truncating passed image path on first NULL https://bugzilla.opensuse.org/show_bug.cgi?id=1026344 Could someone clarify what is expected by EFI spec? Should each Path Name (even intermediate) be NULL terminated, or spec intends to say that only full path must be NULL terminated?
