Joseph Myers 5c112f1b62 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.		2018-07-18 21:04:12 +00:00
