David Gibson 1087504bb3 libfdt: Add necessary header padding in fdt_create() ... At present fdt_create() will succeed if there is exactly enough space to put in the fdt header. However, it sets the off_mem_rsvmap field, a few bytes past that in order to align the memory reservation block. Having block pointers pointing past the end of the fdt is pretty ugly, even if it is just a transient state. Worse, if fdt_resize() is called at exactly the wrong time, it can end up accessing data past the blob's allocated space because of this. So, correct fdt_create() to ensure that there is sufficient space for the alignment padding as well as the plain header. For paranoia, also add a check in fdt_resize() to make sure we don't copy data from outside the blob's bounds. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>		6 years ago
