Upstream-Status: Inappropriate [SDK specific]
|
|
|
|
This patch puts the dynamic loader path in the binaries, SYSTEM_DIRS strings
|
|
and lengths as well as ld.so.cache path in the dynamic loader to specific
|
|
sections in memory. The sections that contain paths have been allocated a 4096
|
|
byte section, which is the maximum path length in linux. This will allow the
|
|
relocating script to parse the ELF binary, detect the section and easily replace
|
|
the strings in a certain path.
