* Versions.def (ld.so): Add GLIBC_2.1.1. * elf/Makefile (routines): Add dl-origin. (tests): Add origtest. Add dependencies for the program. * elf/Versions (ld.so) [GLIBC_2.1.1]: Add _dl_origin_path, _dl_platformlen, _dl_dst_count and _dl_dst_substitute. * elf/dl-deps.c (expand_dst): New macro. Expand DSTs in filename. (_dl_map_object_deps): Use expand_dst to expand DSTs in DT_NEEDED, DT_AUXILIARY, and DT_FILTER filenames. * elf/dl-load.c (expand_dynamic_string_token): Explode into two functions and three macros. (_dl_dst_count, _dl_dst_substitute): New functions. * elf/dl-dst.h: New file. * elf/dl-open.c (_dl_open): Take extra parameter with address of caller. Pass address in args structure. (dl_open_worker): Recognize and expand DSTs in filename. * elf/ldsodefs.h (_dl_open): Adapt prototype. * elf/dlopen.c (dlopen_doit): Pass caller address to _dl_open. (__dlopen_check): Pass caller address to dlopen_doit in args. * elf/dlopendoit.c: Likewise. * iconv/gconv_dl.c: Adapt call of _dl_open. * nss/nsswitch.c: Likewise. * elf/origtest.c: New file. * sysdeps/generic/dl-origin.h: Moved to... * sysdeps/generic/dl-origin.c: ...here. * sysdeps/unix/sysv/linux/dl-origin.h: Moved to... * sysdeps/unix/sysv/linux/dl-origin.c: ...here.
