For right now (the immediate present) a work-around is to use the 'memmove' subroutine as the resolution of any reference to the symbol 'memcpy'. The quick-and-dirty way to do this, is to overwrite with "memmove\0" the unused {DT_NULL}.d_un field [which is 8 bytes on x86_64] of the PT_DYNAMIC section, then change the {'memcpy'}.st_name field of the DT_SYMTAB to designate the overwritten substring. The PT_DYNAMIC segment appears after the DT_STRTAB, so the {'memcpy'}.st_name value [now {'memmove'}.st_name] will be some much larger index than previously. Another way might be to re-order the DT_NEEDED entries in the PT_DYNAMIC segment so that "ld-linux.so.2" comes first, lop off the first DT_NEEDED by increasing the address and decreasing the size by 2*sizeof(void *), overwriting the "ld-linux.so.2" in the DT_STRTAB with "memmove", then setting {'memcpy'}.st_name. ld-linux.so.2 will be there anyway. -- -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
