I'm processing multiboot_tag_mmap and the multiboot_mmap_entry.zero
isn't zero. As best as I can tell grub isn't initializing it. Here is
the code from grub-core/loader/i386/multiboot_mbi.c:
/* Helper for grub_fill_multiboot_mmap. */
static int
grub_fill_multiboot_mmap_iter (grub_uint64_t addr, grub_uint64_t size,
grub_memory_type_t type, void *data)
{
struct multiboot_mmap_entry **mmap_entry = data;
(*mmap_entry)->addr = addr;
(*mmap_entry)->len = size;
(*mmap_entry)->type = type;
(*mmap_entry)->size = sizeof (struct multiboot_mmap_entry) - sizeof
((*mmap_entry)->size);
(*mmap_entry)++;
return 0;
}
And similar code in grub-core/loader/multiboot_mbi2.c:
/* Helper for grub_fill_multiboot_mmap. */
static int
grub_fill_multiboot_mmap_iter (grub_uint64_t addr, grub_uint64_t size,
grub_memory_type_t type, void *data)
{
struct multiboot_mmap_entry **mmap_entry = data;
(*mmap_entry)->addr = addr;
(*mmap_entry)->len = size;
(*mmap_entry)->type = type;
(*mmap_entry)++;
return 0;
}
And I'd expect to see:
(*mmap_entry)->zero = 0;
Is there a reason its not being zeroed?
