All the applications + * that re-layout the internal of ELF will layout all sections in ascending + * order of their file offsets. After the re-layout, the data2 section will + * still be the LAST section in the section header vector, but its file offset + * is now being pushed far away down, and causes part of it not to be mapped + * in (ie. not covered by the load segment entry in PHDR vector), therefore + * causes the new binary to fail. + * + * The solution is to modify the unexec algorithm to insert the new data2 + * section header right before the new bss section header, so their file + * offsets will be in the ascending order. Since some of the section's (all + * sections AFTER the bss section) indexes are now changed, we also need to + * modify some fields to make them point to the right sections. This is done + * by macro PATCH_INDEX. All the fields that need to be patched are: + * + * 1.
