Attached is the patch file, and an "output" from the LEAK_HUNTING=1 on the
real target system that actually doesn't have an MMU where the first leak
(ptr_to_globals) is fixed (but with potential problems for sigexit(), but
not the other one.
The first leak is straightforward, at the start of hush_main() it does
INIT_G() which does an xmalloc(), but there was never a corresponding free.
With an MMU, that's fine because everything disappears, but with NOMMU,
it's a problem. So I added the free(ptr_to_globals) to solve that. It is
inside the # if ENABLE_FEATURE_CLEANUP, and because it is always necessary
when there is no MMU, busybox should probably automatically set
ENABLE_FEATURE_CLEANUP if BB_MMU is 0.
Thanks for catching that sigexit() uses the globals. So it seems the thing
to do is to do instead is:

}
The other leak is difficult to explain "exactly". It mostly doesn't happen
on a system with a real MMU, but it happens reliably on my actual target
which has only 1 processor and no MMU. If you run the new hunt_leaktool.sh
on the attached "output.on_target.txt" it will show the leak. If you look
carefully at the output file, the free() is happening, but it is always 0,
so it doesn't free anything. The pointer to the lost memory is being
overwritten by some other task which somehow has the same space allocated
for its stack. I was able to prove that by using a JTAG remote gdb and
putting a hardware watchpoint on the location where the lost memory pointer
was stored. Unfortunately, the remote gdb has no way to understand the
source being debugged. I can say that it was something else inside busybox
that overwrote it, but because I use FDPIC (where busybox is a blessing vs
a curse for FLAT executables with no mmu), there is always only one copy of
busybox in memory, so It's pretty hard to figure out how that stack is
getting wiped out; it could be a bug in the linux kernel, the C libraries,
or the fdpic compiler but I would think it would cause a whole lot more
problems than that one leak if it was any of those, It does raise concern
for the subsequent lines of code
close(channel[1])
return chanel[2];
because those variables are also close by in the stack frame. However, both
before and after my patch I haven't seen any unexpected behavior of any
shell scripts (except the memory leaking in the before case) on my target
processor, nor any crashes or other bad behavior on that system.
