Keep only ELF_RTYPE_CLASS_{PLT|COPY} bits for prelink
prelink runs ld.so with the environment variable LD_TRACE_PRELINKING set to dump the relocation type class from _dl_debug_bindings. prelink has the following relocation type classes: #define RTYPE_CLASS_VALID 8 #define RTYPE_CLASS_PLT (8|1) #define RTYPE_CLASS_COPY (8|2) #define RTYPE_CLASS_TLS (8|4) where ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA has a conflict with RTYPE_CLASS_TLS. Since prelink only uses ELF_RTYPE_CLASS_PLT and ELF_RTYPE_CLASS_COPY bits, we should clear the other bits when the DL_DEBUG_PRELINK bit is set. [BZ #19178] * elf/dl-lookup.c (RTYPE_CLASS_VALID): New. (RTYPE_CLASS_PLT): Likewise. (RTYPE_CLASS_COPY): Likewise. (RTYPE_CLASS_TLS): Likewise. (_dl_debug_bindings): Use RTYPE_CLASS_TLS and RTYPE_CLASS_VALID to set relocation type class for DL_DEBUG_PRELINK. Keep only ELF_RTYPE_CLASS_PLT and ELF_RTYPE_CLASS_COPY bits for DL_DEBUG_PRELINK.
