We unregister script images during their execution, to prevent a "boot" command from re-executing the containing script. This also has the side effect of preventing executing scripts from showing up within the Linux magic initrd image (or the Multiboot module list). Additional logic in bzimage.c and efi_file.c prevents a currently executing kernel from showing up within the magic initrd image. Similar logic in multiboot.c prevents the Multiboot kernel from showing up as a Multiboot module. This still leaves some corner cases that are not covered correctly. For example: when using a gzip-compressed kernel image, nothing will currently hide the original compressed image from the magic initrd. Fix by moving the logic that temporarily unregisters the current image from script_exec() to image_exec(), so that it applies to all image types, and simplify the magic initrd and Multiboot module list construction logic on the basis that no further filtering of the registered image list is necessary. This change has the side effect of hiding currently executing EFI images from the virtual filesystem exposed by iPXE. For example, when using iPXE to boot wimboot, the wimboot binary itself will no longer be visible within the virtual filesystem. Signed-off-by: Michael Brown <mcb30@ipxe.org> |
