Mon Jun 10 06:14:03 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* sysdeps/mach/hurd/dl-sysdep.c (__open): Define this instead of open.
(__close, __mmap): Likewise define with __ names now.
Mon Jun 10 05:13:18 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* elf/dl-support.c: New file.

(_dl_map_object_from_fd): Initialize it if zero.
* elf/link.h (_dl_pagesize): Remove const.
Sun Jun 9 04:04:26 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* elf/Makefile (routines): Add dl-symbol.
* elf/dl-lookup.c (_dl_symbol_value): Moved to ...
* elf/dl-symbol.c: New file.
* elf/elf.h (Elf32_Xword, Elf32_Sxword): New types.
(Elf32_Section, Elf64_Section): New types, 16 bits.
(Elf32_Sym, Elf64_Sym): Use it.
* elf/dl-deps.c (_dl_open): Moved to ...
* elf/dl-open.c: New file.
* Makefile (routines): Add dl-open.
* elf/Makefile (dl-routines): New variable.
(routines): Add $(dl-routines).
(elide-routines.so): New variable, set to $(dl-routines).
(libdl-inhibit-o): Variable removed; build all flavors of -ldl.
(rtld-routines): All but rtld, dl-sysdep, and dl-minimal moved to
$(dl-routines).
* elf/dl-lookup.c (_dl_lookup_symbol): Remove magic symbol grokage.
* elf/dladdr.c: Use ELFW(ST_BIND) in place of ELF32_ST_BIND.
* elf/dl-load.c (open_path): Use __ names for open and close. Avoid
using strdup.
(_dl_map_object): Likewise.
(_dl_map_object_from_fd): Use __ names for mmap, munmap, and mprotect.
* elf/dl-minimal.c (malloc): Likewise.
* elf/dl-reloc.c (_dl_relocate_object): Likewise.

char is always a byte, no need for a typedef. Section indices are
16-bit quantities in elf64, which already have a typedef Elf64_Half.
Remove partial -lelf implementation. There is now a
separately-distributed `libelf' package that implements it.

* elf/Makefile (libdl.so): Remove commands from this target. The
implicit rule commands are correct, this explicit rule just serves to
add some dependencies.
* elf/dl-lookup.c (_dl_lookup_symbol): Use ELFW(ST_TYPE) in place of
ELF32_ST_TYPE. Likewise ST_BIND.
* elf/do-rel.h (elf_dynamic_do_rel): Likewise R_SYM.

naming.
(ELFW): New macro, likewise for ELFXX_* macro naming.
(_ElfW, _ElfW_1): New macros, subroutines of ElfW and ELF.

elf/dl-runtime.c, elf/dladdr.c, elf/dlclose.c, elf/dlsym.c,
elf/linux-compat.c, elf/rtld.c: Change all uses of `Elf32_XXX' to
`ElfW(XXX)' for wordsize-independence.
Sat Jun 8 20:50:42 1996 Richard Henderson <rth@tamu.edu>
* elf/elf.h: Move Elf64_* types in parity with Elf32 counterparts.
(Elf64_auxv_t): New type.

char is always a byte, no need for a typedef. Section indices are
16-bit quantities in elf64, which already have a typedef Elf64_Half.

implicit rule commands are correct, this explicit rule just serves to
add some dependencies.
* elf/dl-lookup.c (_dl_lookup_symbol): Use ELFW(ST_TYPE) in place of
ELF32_ST_TYPE. Likewise ST_BIND.
* elf/do-rel.h (elf_dynamic_do_rel): Likewise R_SYM.

naming.
(ELFW): New macro, likewise for ELFXX_* macro naming.

The global scope is the searchlist in the main link map. We
|
|
|
|
extend this list if necessary. There is one problem though:
|
|
|
|
since this structure was allocated very early (before the libc
|
|
|
|
is loaded) the memory it uses is allocated by the malloc()-stub
|
|
|
|
in the ld.so. When we come here these functions are not used
|
|
|
|
anymore. Instead the malloc() implementation of the libc is
|
|
|
|
used. But this means the block from the main map cannot be used
|
|
|
|
in an realloc() call. Therefore we allocate a completely new
|
|
|
|
array the first time we have to add something to the locale scope. */

[BZ #77]
Update.
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.

* 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.

* sysdeps/mach/hurd/dl-sysdep.c (__open): Define this instead of open.
(__close, __mmap): Likewise define with __ names now.
Mon Jun 10 05:13:18 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* elf/dl-support.c: New file.
* elf/Makefile (CFLAGS-dl-support.c): New variable.
(routines, elide-routines.so): Add dl-support.
* elf/dl-minimal.c (_dl_pagesize): Remove common defn.
* elf/dl-load.c (_dl_pagesize): Define it here.
(_dl_map_object_from_fd): Initialize it if zero.
* elf/link.h (_dl_pagesize): Remove const.
Sun Jun 9 04:04:26 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* elf/Makefile (routines): Add dl-symbol.
* elf/dl-lookup.c (_dl_symbol_value): Moved to ...
* elf/dl-symbol.c: New file.
* elf/elf.h (Elf32_Xword, Elf32_Sxword): New types.
(Elf32_Section, Elf64_Section): New types, 16 bits.
(Elf32_Sym, Elf64_Sym): Use it.
* elf/dl-deps.c (_dl_open): Moved to ...
* elf/dl-open.c: New file.
* Makefile (routines): Add dl-open.
* elf/Makefile (dl-routines): New variable.
(routines): Add $(dl-routines).
(elide-routines.so): New variable, set to $(dl-routines).
(libdl-inhibit-o): Variable removed; build all flavors of -ldl.
(rtld-routines): All but rtld, dl-sysdep, and dl-minimal moved to
$(dl-routines).
* elf/dl-lookup.c (_dl_lookup_symbol): Remove magic symbol grokage.
* elf/dladdr.c: Use ELFW(ST_BIND) in place of ELF32_ST_BIND.
* elf/dl-load.c (open_path): Use __ names for open and close. Avoid
using strdup.
(_dl_map_object): Likewise.
(_dl_map_object_from_fd): Use __ names for mmap, munmap, and mprotect.
* elf/dl-minimal.c (malloc): Likewise.
* elf/dl-reloc.c (_dl_relocate_object): Likewise.
* elf/dl-minimal.c (_dl_pagesize): New variable.
(malloc): Use that instead of a static variable.
* elf/dl-reloc.c (_dl_relocate_object): Use _dl_pagesize instead of
calling getpagesize.
* elf/dl-load.c (_dl_map_object_from_fd): Likewise.
* elf/link.h: Declare _dl_pagesize.

extract 4-byte magic number, not ElfW(Word). Match EI_CLASS against
native wordsize, either 32 or 64.
* elf/elf.h (Elf64_Byte, Elf64_Section): Typedefs removed. In C a
char is always a byte, no need for a typedef. Section indices are
16-bit quantities in elf64, which already have a typedef Elf64_Half.
Remove partial -lelf implementation. There is now a
separately-distributed `libelf' package that implements it.
* elf/dl-lookup.c: Don't #include <libelf.h> any more.
(_dl_elf_hash): New function, moved from
libelf.h:elf_hash.

* elf/Makefile (headers): Remove libelf.h.
(extra-libs): Remove libelf.
(libelf-routines): Variable removed.
* elf/Makefile (libdl.so): Remove commands from this target. The
implicit rule commands are correct, this explicit rule just serves to
add some dependencies.
* elf/dl-lookup.c (_dl_lookup_symbol): Use ELFW(ST_TYPE) in place of
ELF32_ST_TYPE. Likewise ST_BIND.
* elf/do-rel.h (elf_dynamic_do_rel): Likewise R_SYM.
* elf/link.h (ElfW): New macro for wordsize-independent ElfXX_* type
naming.
(ELFW): New macro, likewise for ELFXX_* macro naming.
(_ElfW, _ElfW_1): New macros, subroutines of ElfW and ELF.
Sat Jun 8 20:52:38 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>

elf/dl-runtime.c, elf/dladdr.c, elf/dlclose.c, elf/dlsym.c,
elf/linux-compat.c, elf/rtld.c: Change all uses of `Elf32_XXX' to
`ElfW(XXX)' for wordsize-independence.
Sat Jun 8 20:50:42 1996 Richard Henderson <rth@tamu.edu>
* elf/elf.h: Move Elf64_* types in parity with Elf32 counterparts.
(Elf64_auxv_t): New type.
