From 20fe49b93a8807b7e91732d5a1b21a2d99472793 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 18 Mar 2005 11:11:42 +0000 Subject: * include/link.h (struct link_map): Remove l_opencount. Add l_removed. Change type of l_idx to int. * elf/dl-close.c: Basically rewrite. Do not use l_opencount to determine whether a DSO has to be unloaded. Instead compute this in this function. * elf/dl-deps.c: No need to manipulate l_opencount anymore. * elf/dl-lookup.c: Likewise. * elf/rtld.c: Likewise * elf/dl-open.c: Likewise. Use l_init_called to determine whether object was just loaded. * elf/dl-fini.c: Bump l_direct_opencount instead of l_opencount. * elf/dl-load.c (_dl_map_object_from_fd): Do not recognize DSO which is about to be unloaded as a match. (_dl_map_object): Likewise. * elf/do-lookup.h (do_lookup_x): Do not look into DSO which is about to be unloaded. * elf/circleload1.c: Don't use l_opencount anymore. * elf/neededtest.c: Likewise. * elf/neededtest2.c: Likewise. * elf/neededtest3.c: Likewise. * elf/neededtest4.c: Likewise. * elf/unload.c: Likewise. * elf/unload2.c: Likewise. * elf/loadtest.c: Likewise. * elf/rtld.c: Preloading errors are now never fatal. 2005-03-08 Jakub Jelinek * elf/Makefile: Add rules to build and run unload5 test. * elf/unload5.c: New file. 2005-03-08 Jakub Jelinek * elf/Makefile: Add rules to build and run unload4 test. * elf/unload4.c: New file. * elf/unload4mod1.c: New file. * elf/unload4mod2.c: New file. * elf/unload4mod3.c: New file. * elf/unload4mod4.c: New file. --- elf/dl-load.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'elf/dl-load.c') diff --git a/elf/dl-load.c b/elf/dl-load.c index 97e1e0089c..d9c2da2ac7 100644 --- a/elf/dl-load.c +++ b/elf/dl-load.c @@ -849,7 +849,7 @@ _dl_map_object_from_fd (const char *name, int fd, struct filebuf *fbp, /* Look again to see if the real name matched another already loaded. */ for (l = GL(dl_ns)[nsid]._ns_loaded; l; l = l->l_next) - if (l->l_ino == st.st_ino && l->l_dev == st.st_dev) + if (l->l_removed == 0 && l->l_ino == st.st_ino && l->l_dev == st.st_dev) { /* The object is already loaded.
