data = elf_getdata(scn, data) returns garbage for shdr.sh_type == SHT_NOBITS
by Anthony G. Basile 12 Jul '11

Hi everyone, A few days ago I was was writing some code to go over the data of various sections. I know that sections marked SHT_NOBITS don't have data, but I was expecting data = elf_getdata(scn, data) to return NULL. Instead it return some value which, of course, proptly led to a seg fault when I tried to dereference it. Of course, I can fix this by avoiding elf_getdata() if(shdr.sh_type == SHT_NOBITS) but it would probably be a good idea if elf_getdata returned NULL. I haven't had time to jump into the source to see where this might be added, ie sorry no patch. -- Anthony G. Basile, Ph. D.
