S390: Fix elf/tst-audit25[ab]
|
|
|
|
If glibc is configured with --disable-default-pie and build on
|
|
s390 with -O3, the tests elf/tst-audit25a and elf/tst-audit25b are
|
|
failing as there are additional la_symbind lines for free and malloc.
|
|
It turns out that those belong to the executable. In fact those are
|
|
the PLT-stubs. Furthermore la_symbind is also called for calloc and
|
|
realloc symbols, but those belong to libc.
|
|
|
|
Those functions are not called at all, but dlsym'ed in
|
|
elf/dl-minimal.c:
|
|
__rtld_malloc_init_real (struct link_map *main_map)
|
|
{
|
|
...
|
|
void *new_calloc = lookup_malloc_symbol (main_map, "calloc", &version);
|
|
void *new_free = lookup_malloc_symbol (main_map, "free", &version);
|
|
void *new_malloc = lookup_malloc_symbol (main_map, "malloc", &version);
|
|
void *new_realloc = lookup_malloc_symbol (main_map, "realloc", &version);
|
|
...
|
|
}
|
|
|
|
Therefore, this commit just ignored symbols with LA_SYMB_DLSYM flag.
