Title:
linux-user elf loader issue
Status in QEMU:
Expired
Bug description:
all versions up to 4.0 (I didn't test others)
file affected linux-user/elfload.c
function load_elf_image
if (phdr[i].p_type == PT_LOAD) {
- abi_ulong a = phdr[i].p_vaddr - phdr[i].p_offset;
+ abi_ulong a = phdr[i].p_vaddr ; // - phdr[i].p_offset;
if (a < loaddr) {
loaddr = a;
To the best of my understanding of the elf format p_offset is not a
virtual offset. In fact, when I load statically compiled applications,
the load fails because the libc before main is trying to access phdr
in the executable image but that memory is not mapped -- this is
caused by the wrong loaddr above.
