3 | This patch puts the dynamic loader path in the binaries, SYSTEM_DIRS strings | ||
4 | and lengths as well as ld.so.cache path in the dynamic loader to specific | ||
5 | sections in memory. The sections that contain paths have been allocated a 4096 | ||
6 | byte section, which is the maximum path length in linux. This will allow the | ||
7 | relocating script to parse the ELF binary, detect the section and easily replace | ||
8 | the strings in a certain path. | ||
