Avoid insecure usage of tmpnam in tests. ...
Various glibc testcases use tmpnam in ways subject to race conditions
(generate a temporary file name, then later open that file without
O_EXCL).
This patch fixes those tests to use mkstemp - generally a minimal
local fix to use mkstemp instead of tmpnam, rather than a larger fix
to use other testsuite infrastructure for temporary files. The
unchanged use of tmpnam in posix/wordexp-test.c would fail safe in the
event of a race (it's generating a name for use with mkdir rather than
for a file to be opened for writing).
Tested for x86_64.
* grp/tst_fgetgrent.c: Include <unistd.h>.
(main): Use mkstemp instead of tmpnam.
* io/test-utime.c (main): Likewise.
* posix/annexc.c (macrofile): Change to modifiable array.
(get_null_defines): Use mkstemp instead of tmpnam. Do not remove
macrofile here.
* posix/bug-getopt1.c: Include <stdlib.h>.
(do_test): Use mkstemp instead of tmpnam.
* posix/bug-getopt2.c: Include <stdlib.h>.
(do_test): Use mkstemp instead of tmpnam.
* posix/bug-getopt3.c: Include <stdlib.h>.
(do_test): Use mkstemp instead of tmpnam.
* posix/bug-getopt4.c: Include <stdlib.h>.
(do_test): Use mkstemp instead of tmpnam.
* posix/bug-getopt5.c: Include <stdlib.h>.
(do_test): Use mkstemp instead of tmpnam.
* stdio-common/bug7.c: Include <stdlib.h> and <unistd.h>.
(main): Use mkstemp instead of tmpnam.
* stdio-common/tst-fdopen.c: Include <stdlib.h>.
(main): Use mkstemp instead of tmpnam.
* stdio-common/tst-ungetc.c: Include <stdlib.h>.
(main): use mkstemp instead of tmpnam.
* stdlib/isomac.c (macrofile): Change to modifiable array.
(get_null_defines): Use mkstemp instead of tmpnam. Do not remove
macrofile here.
