* elf/dl-load.c (_dl_map_object_from_fd): Add additional parameter for original name of the DSO. Add it to the name list of the DSO if it is actually given. (_dl_map_object): Keep track of whether an audit module rewrote the file name. If yes, pass the original name to _dl_map_object_from_fd in a new parameter, otherwise NULL. When debugging is enabled, log the change of the file name. * sysdeps/mach/hur/dl-sysdep.c: Adjust commented-out call to _dl_map_object_from_fd. * elf/Makefile: Build and run tst-audit11 and tst-audit12. * elf/tst-audit11.c: New file * elf/tst-auditmod11.c: New file. * elf/tst-audit11mod1.c: New file. * elf/tst-audit11mod2.c: New file. * elf/tst-audit11mod2.map: New file. * elf/tst-audit12.c: New file * elf/tst-auditmod12.c: New file. * elf/tst-audit12mod1.c: New file. * elf/tst-audit12mod2.c: New file. * elf/tst-audit12mod2.map: New file. * elf/tst-audit12mod3.c: New file.
