From 752a2a50d4574791b2861653d4352c6b6e4b97ff Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 19 Aug 2000 07:17:09 +0000 Subject: Update. 2000-08-19 Ulrich Drepper * elf/Versions [ld] (GLIBC_2.2): Export _dl_check_map_versions. * elf/dl-deps.c (_dl_map_object_deps): If object was dependency of a dynamically loaded object remove old l_initfini list. * elf/dl-libc.c (free_mem): Used as __libc_subfreeres callback to remove some dynamically allocated memory blocks in the dynamic loading data structures. * elf/dl-load.c (add_name_to_object): Initialize dont_free to 0. * elf/dl-open.c (dl_open_workder): Don't call _dl_check_all_versions. Instead call _dl_check_map_versions only for the dependencies. * elf/rtld.c: Avoid unneccessary initializations. Mark l_libname information of initial objects as not free-able. * sysdeps/generic/ldsodefs.h (struct libname_list): Add dont_free element. * elf/filter.c: Call mtrace. * elf/restest1.c: Likewise. Close the objects. * elf/loadtest.c: Call mtrace. Check result of dlclose. Print more debug information. * elf/constload1.c: Add comment explaining not freed memory. --- elf/constload1.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'elf/constload1.c') diff --git a/elf/constload1.c b/elf/constload1.c index 4640b77..e0ddae9 100644 --- a/elf/constload1.c +++ b/elf/constload1.c @@ -18,6 +18,10 @@ main (void) error (EXIT_FAILURE, errno, "cannot load module \"constload2.so\""); foo = dlsym (h, "foo"); ret = foo (); + /* Note that the following dlclose() call cannot unload the objects. + Due to the introduced relocation dependency constload2.so depends + on constload3.so and the dependencies of constload2.so on constload3.so + is not visible to ld.so since it's done using dlopen(). */ if (dlclose (h) != 0) { puts ("failed to close"); -- cgit v1.1
