There are 3 ways BusyBox can handle buffer allocations:
- Use malloc. This costs code size for the call to xmalloc.
- Put them on stack. For some very small machines with limited stack
space, this can be deadly. For most folks, this works just fine.
- Put them in BSS. This works beautifully for computers with a real
MMU (and OS support), but wastes runtime RAM for uCLinux. This
behavior was the only one available for BusyBox versions 0.48 and
earlier.
