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/unload6mod3.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 elf/unload6mod3.c (limited to 'elf/unload6mod3.c') diff --git a/elf/unload6mod3.c b/elf/unload6mod3.c new file mode 100644 index 0000000..7b29e1d --- /dev/null +++ b/elf/unload6mod3.c @@ -0,0 +1,23 @@ +#include +#include +#include + +static void *h; + +static void __attribute__((constructor)) +mod3init (void) +{ + h = dlopen ("unload6mod1.so", RTLD_LAZY); + if (h == NULL) + { + puts ("dlopen unload6mod1.so failed"); + fflush (stdout); + _exit (1); + } +} + +static void __attribute__((destructor)) +mod3fini (void) +{ + dlclose (h); +} -- cgit v1.1
