| Adjust-DT_MIPS_RLD_MAP_REL-dynamic-section-entry-if-prese.patch | Adjust DT_MIPS_RLD_MAP_REL dynamic section entry if present `patchelf --set-rpath` corrupted executables on mips32el: the dynamic liker crushed with Segmentation fault when loading any executable with RPATH added that way. The problem was around the MIPS-specific mechanism of setting up the debug map pointer. When DT_MIPS_RLD_MAP_REL entry in the dynamic section is not zero, it holds the relative address of __RLD_MAP -- an offset relative to this dynamic section entry. Dynamic linker puts the pointer to the `r_debug` structure there. When patchelf updates the executable RPATH, it moves the .dynamic section both in the binary and in memory, while __RLD_MAP is not moved in memory, since it belongs to special .rld_map section that has type PROGBITS. So, the offset stored in DT_MIPS_RLD_MAP_REL entry is not valid anymore and should be updated. This commit adds the necessary update. Here we also import DT_MIPS_RLD_MAP_REL definition in elf.h form glibc commit a2057c984e4314c3740f04cf54e36c824e4c8f32. DT_MIPS_RLD_MAP_REL |

| Adjust-PT_MIPS_ABIFLAGS-segment-if-present.patch | Adjust PT_MIPS_ABIFLAGS segment if present When loading the executable on MIPS, the dynamic loader looks for MIPS ABI flags using PT_MIPS_ABIFLAGS header. The flags themselves are stored in the .MIPS.abiflags section, so the header must be updated when the section is moved. Here we also import PT_MIPS_ABIFLAGS definition from glibc commit 0bd956720c457ff054325b48f26ac7c91cb060e8. |
