| 4 | Subject: [PATCH] nativesdk-libcap: Raise the size of arrays containing dl |
| 5 | paths |
| 6 | |
| 7 | This patch puts the dynamic loader path in the binaries, SYSTEM_DIRS strings |
| 8 | and lengths as well as ld.so.cache path in the dynamic loader to specific |
| 9 | sections in memory. The sections that contain paths have been allocated a 4096 |
| 10 | byte section, which is the maximum path length in linux. This will allow the |
| 11 | relocating script to parse the ELF binary, detect the section and easily replace |
| 12 | the strings in a certain path. |
| 13 | |
| 14 | Upstream-Status: Inappropriate [SDK specific] |
