Sean Cross b35d65c3e1 loader: skip zeroing when we hit a page boundary ... Previously, we would unconditionally zero out the remainder of a page when finished copying. We wrapped to PAGE_SIZE in order to avoid corrupting another process' memory. However, an issue was discovered under the following circumstances: 1. There are fewer than 4096 bytes of `.bss` 2. The `.bss` ends on a page boundary Under these conditions, the loader would load the section before the `.bss` into the page, then clear out the `.bss`, and finally clear the entire page, overwriting the previous section. Skip the remainder-of-page clearout when the `.bss` ends on a page boundary, rather than clearing the entire page. Signed-off-by: Sean Cross <sean@xobs.io>		2022-10-20 11:27:48 +08:00
