From bfc832ccf15e467b6271e8b237e467a30efd3d12 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 27 Apr 2005 01:39:11 +0000 Subject: * elf/dl-close.c: Include stddef.h. (_dl_close): If called recursively, just remember GC needs to be rerun and decrease l_direct_opencount. Avoid GC if l_direct_opencount decreased to 1. Rerun GC at the end if any destructor unloaded some additional libraries. * elf/Makefile: Add rules to build and run unload6 test. * elf/unload6.c: New test. * elf/unload6mod1.c: New file. * elf/unload6mod2.c: New file. * elf/unload6mod3.c: New file. * malloc/hooks.c (mem2chunk_check): Add magic_p argument, set *magic_p if magic_p is not NULL. (top_check): Invoke MALLOC_FAILURE_ACTION if MORECORE failed. (malloc_check): Fail if sz == -1. (free_check): Adjust mem2chunk_check caller. (realloc_check): Likewise. Fail if bytes == -1. If bytes == 0 and oldmem != NULL, call free_check and return NULL. If reallocating and returning NULL, invert magic byte again to make oldmem valid region for further checking. (memalign_check): Fail if bytes == -1. * malloc/Makefile: Add rules to build and run tst-mcheck. * malloc/tst-mcheck.c: New test. --- elf/unload6.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 elf/unload6.c (limited to 'elf/unload6.c') diff --git a/elf/unload6.c b/elf/unload6.c new file mode 100644 index 0000000000..1efc7eb841 --- /dev/null +++ b/elf/unload6.c @@ -0,0 +1,30 @@ +#include +#include + +int +main (void) +{ + void *h = dlopen ("unload6mod1.so", RTLD_LAZY); + if (h == NULL) + { + puts ("dlopen unload6mod1.so failed"); + return 1; + } + + int (*fn) (int); + fn = dlsym (h, "foo"); + if (fn == NULL) + { + puts ("dlsym failed"); + return 1; + } + + int val = fn (16); + if (val != 24) + { + printf ("foo returned %d != 24\n", val); + return 1; + } + + return 0; +} -- cgit 1.4.1
