From 5f21997b9d6a49ddbed85b044e2be7b182c095a2 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 18 Oct 2004 23:17:46 +0000 Subject: Update. 2004-10-18 Jakub Jelinek * elf/dl-libc.c (__libc_dlsym_private, __libc_register_dl_open_hook): New functions. (__libc_dlopen_mode): Call __libc_register_dl_open_hook and __libc_register_dlfcn_hook. * dlfcn/Makefile (routines, elide-routines.os): Set. Add rules to build and test tststatic2. * dlfcn/tststatic2.c: New test. * dlfcn/modstatic2.c: New test module. * dlfcn/dladdr.c: Call _dlfcn_hook from libdl.so if not NULL. Define __ prefixed routine in libc.a and in libdl.a just call it. * dlfcn/dladdr1.c: Likewise. * dlfcn/dlclose.c: Likewise. * dlfcn/dlerror.c: Likewise. * dlfcn/dlinfo.c: Likewise. * dlfcn/dlmopen.c: Likewise. * dlfcn/dlopen.c: Likewise. * dlfcn/dlopenold.c: Likewise. * dlfcn/dlsym.c: Likewise. * dlfcn/dlvsym.c: Likewise. * dlfcn/sdladdr.c: New file. * dlfcn/sdladdr1.c: New file. * dlfcn/sdlclose.c: New file. * dlfcn/sdlerror.c: New file. * dlfcn/sdlinfo.c: New file. * dlfcn/sdlopen.c: New file. * dlfcn/sdlsym.c: New file. * dlfcn/sdlvsym.c: New file. * dlfcn/Versions (libdl): Export _dlfcn_hook@GLIBC_PRIVATE. * include/dlfcn.h (DL_CALLER_DECL, DL_CALLER RETURN_ADDRESS): Define. (struct dlfcn_hook): New type. (_dlfcn_hook): New extern decl. (__dlopen, __dlclose, __dlsym, __dlerror, __dladdr, __dladdr1, __dlinfo, __dlmopen, __libc_dlsym_private, __libc_register_dl_open_hook, __libc_register_dlfcn_hook): New prototypes. (__dlvsym): Use DL_CALLER_DECL. * include/libc-symbols.h: Define libdl_hidden_proto and friends. * malloc/arena.c (_dl_open_hook): Extern decl. (ptmalloc_init): Don't call _dl_addr when dlopened from statically linked programs but don't use brk for them either. --- include/libc-symbols.h | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'include/libc-symbols.h') diff --git a/include/libc-symbols.h b/include/libc-symbols.h index e7880b6c46..7dd0d2901b 100644 --- a/include/libc-symbols.h +++ b/include/libc-symbols.h @@ -762,6 +762,24 @@ for linking") # define libresolv_hidden_data_ver(local, name) #endif +#if defined NOT_IN_libc && defined IS_IN_libdl +# define libdl_hidden_proto(name, attrs...) hidden_proto (name, ##attrs) +# define libdl_hidden_def(name) hidden_def (name) +# define libdl_hidden_weak(name) hidden_weak (name) +# define libdl_hidden_ver(local, name) hidden_ver (local, name) +# define libdl_hidden_data_def(name) hidden_data_def (name) +# define libdl_hidden_data_weak(name) hidden_data_weak (name) +# define libdl_hidden_data_ver(local, name) hidden_data_ver (local, name) +#else +# define libdl_hidden_proto(name, attrs...) +# define libdl_hidden_def(name) +# define libdl_hidden_weak(name) +# define libdl_hidden_ver(local, name) +# define libdl_hidden_data_def(name) +# define libdl_hidden_data_weak(name) +# define libdl_hidden_data_ver(local, name) +#endif + #ifdef HAVE_BUILTIN_REDIRECTION # define libc_hidden_builtin_proto(name, attrs...) libc_hidden_proto (name, ##attrs) # define libc_hidden_builtin_def(name) libc_hidden_def (name) -- cgit v1.2.3
