+ Add support for namespaces in the dynamic linker.
+ * dlfcn/Makefile (libdl-routines): Add dlmopen.
+ * dlfcn/Versions [libdl, GLIBC_2.3.4]: Add dlmopen.
+ * dlfcn/dlfcn.h: Define Lmid_t, LM_ID_BASE, and LM_ID_NEWLM.
+ Declare dlmopen. Document RTLD_DI_LMID.
+ * dlfcn/dlinfo.c: Handle RTLD_DI_LMID.
+ * dlfcn/dlmopen.c: New file.
+ * dlfcn/dlopen.c: Pass new parameter to _dl_open.
+ * dlfcn/dlopenold.c: Likewise.
+ * elf/dl-addr.c: Adjust for removal of GL(dl_loaded).
+ * elf/dl-caller.c: Likewise.
+ * elf/dl-close.c: Likewise.
+ * elf/dl-conflict.c: Likewise.
+ * elf/dl-debug.c: Likewise.
+ * elf/dl-lookup.c: Likewise.
+ * elf/dl-sym.c: Likewise.
+ * elf/dl-version.c: Likewise.
+ * elf/do-lookup.h: Likewise.
+ * elf/rtld.c: Likewise.
+ * sysdeps/unix/sysv/linux/i386/dl-librecon.h: Likewise.
+ * elf/dl-depsc: Likewise. Add new parameter to _dl_map_object.
+ * elf/dl-fini.c: Call destructors in all namespaces.
+ * elf/dl-iteratephdr.c: Compute total nloaded. Adjust for removal of
+ GL(dl_loaded).
+ * elf/dl-libc.c: Pass new parameter to _dl_open. Adjust for removal
+ of GL(dl_loaded).
+ * elf/dl-load.c (_dl_map_object_from_fd): Don't load ld.so a second
+ time. Reuse the one from the main namespace in all others.
+ Pass new parameter to _dl_new_object.
+ Adjust for removal of GL(dl_loaded).
+ * elf/dl-object.c: Take new parameter. Use it to initialize l_ns.
+ Adjust for removal of GL(dl_loaded).
+ * elf/dl-open.c (_dl_open): Take new parameter.
+ Adjust for removal of GL(dl_loaded).
+ * elf/dl-support.c: Replace global _dl_loaded etc variables with
+ _dl_ns variable.
+ * include/dlfcn.h: Adjust prototype of _dl_open.
+ Define __LM_ID_CALLER.
+ * include/link.h: Add l_real, l_ns, and l_direct_opencount elements.
+ * sysdeps/generic/dl-tls.c: Bump TLS_STATIC_SURPLUS. Since libc is
+ using TLS we need memory appropriate to the number of namespaces.
+ * sysdeps/generic/ldsodefs.h (struct rtld_global): Replace _dl_loaded,
+ _dl_nloaded, _dl_global_scope, _dl_main_searchlist, and
+ _dl_global_scope_alloc with _dl_ns element. Define DL_NNS.
+ Adjust prototypes of _dl_map_object and member in rtld_global_ro.
+ * malloc/malloc.c: Include <dlfcn.h>.
+ * malloc/arena.c (ptmalloc_init): If libc is not in primary namespace,
+ never use brk.
+ * elf/Makefile: Add rules to build and run tst-dlmopen1 and
+ tst-dlmopen2.
+ * elf/tst-dlmopen1.c: New file.
+ * elf/tst-dlmopen1mod.c: New file.
+ * elf/tst-dlmopen2.c: New file.
+
+ * elf/dl-close.c: Improve reference counting by tracking direct loads.
+ * elf/dl-lookup.c (add_dependency): Likewise.
+ * elf/dl-open.c (dl_open_worker): Likewise.
+ * elf/rtld.c (dl_main): Likewise.
+
+2004-09-09 GOTO Masanori <gotom@debian.or.jp>
+
+ [BZ #77]
+ * elf/dl-close.c: Count down l_opencount to check not only for
+ l_reldeps, but also l_initfini.
